Title: Replication of content to one or more servers

Description:
FIELD OF THE INVENTION 
     The present invention generally relates to replica of data, and more particularly, to methods and systems for automatic replica of content to certain servers in a networking environment based on, amongst other metrics, location of third parties accessing information in a social networking environment. 
     BACKGROUND 
     Computer networking systems are fairly ubiquitous in today&#39;s society. These networking systems require vast amounts of storage space to hold content created and posted by the users. This content can range from simple text documents, to pictures and a host of other media types. 
     A subset of computing networking systems can include social networks which appear to be ever growing and the distribution of its usage being international. Social network providers are increasing their capacity and distributing their content servers or caching servers throughout the world to meet user&#39;s expectation of performance. The mechanism of distributing or replicating content is based on the location of the user who is publishing or posting the content. Also, typically, the content is published on all of the servers throughout the social network, e.g., networking environment, generally without regard to storage space. 
     SUMMARY 
     In a first aspect of the invention, a method comprises obtaining content from a user within a networked environment. The method further comprises analyzing information of one or more third parties that have access to the networked environment and who have an association with the user. The method further comprises replicating the content to one or more servers within the networked environment based on the analyzed information of the one or more third parties. 
     In another aspect of the invention, a system is implemented in hardware and comprises a replication engine implemented in at least one server within a networking environment using a processing system. The at least one server receives content from a first user, and the replication engine analyzes information associated with third party users within the networking environment and provides instructions to replicate the content to one or more servers closest to the third party users based on the analyzed information. 
     In another aspect of the invention, a computer program product comprises a computer readable storage device having readable program code embodied in the storage device and when executed on a computing system is operable to: obtain content from a user; determine locations of third party users wanting to retrieve the content; determine a nearest server to each of the third party users wanting to retrieve the content; and replicate the content for storage on the nearest server of each of the third party users wanting to retrieve the content. 
     In another aspect of the invention, a computer system for replication of content in a networked environment comprises a CPU, a computer readable memory and a computer readable storage media. The computer system further comprises: program instructions to connect a user to a local server; program instructions to upload content to either the local server or a central server within a networked environment; program instructions to query a replication engine that the content is uploaded to either the local server or the central server within a networked environment; program instructions to provide a replication analysis by determining certain metrics of at least a plurality of third party users having access to the networked environment and that are associated with the user; and program instructions to replicate the content to at least one server that is nearest to the third party users based on the replication analysis. Each of the program instructions are stored on the computer readable storage media for execution by the CPU via the computer readable memory. 
     In another aspect of the invention, a method of deploying a system for replicating content in a networking environment comprises providing a computer infrastructure, being operable to: obtain content from a user within a networked environment; analyze information of a plurality of third parties that have access to the networked environment and who have an association with the user; and replicate the content to a nearest server to each of the plurality of third parties within the networked environment based on the analyzed information.

     DETAILED DESCRIPTION 
     The present invention generally relates to replica of data, and more particularly, to methods and systems for automatic replica of content to certain servers in a cloud environment based on, amongst other metrics, location of third parties accessing information in a social networking environment. In more specific aspects of the present invention, the systems and methods provide a mechanism for replicating the content in servers located nearest third parties (e.g., followers or friends of the user) who are accessing information of a user. The replication of content can be based on such metrics as: specific types of content which are likely to be accessed by the third parties, specific servers at locations nearest the third parties, as well as a host of other features as described herein. 
     As a further example, the methods and systems of the present invention obtain location information of followers and friends, e.g., third parties associated with a particular user, as well as usage patterns of the third parties, e.g., types of information and data retrieved by the third parties, patterns of traffic, etc. The methods and systems of the present invention can then use this information to replicate content (i.e., certain content from an originating user) to servers closest to the third parties accessing such content, amongst other metrics and criteria. In this way, it is no longer necessary to replicate data at each datacenter in the cloud environment or social network. 
     Advantageously, the present invention increases performance of the cloud environment by, for example, decreasing retrieval times of third party access to content, as well as reducing the replication of content throughout the cloud environment. For example, by implementing the systems and methods of the present invention, there is no need to replicate the content to every datacenter, e.g., server, thereby more efficiently and effectively using storage space in the cloud environment. 
     It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementations of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed. 
     Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models. 
     Characteristics are as follows: 
     On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service&#39;s provider. 
     Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs). 
     Resource pooling: the provider&#39;s computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter). 
     Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time. 
     Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service. 
     Service Models are as follows: 
     Software as a Service (SaaS): the capability provided to the consumer is to use the provider&#39;s applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based email). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings. 
     Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations. 
     Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls). 
     Deployment Models are as follows: 
     Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises. 
     Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises. 
     Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services. 
     Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds). 
     A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure including a network of interconnected nodes. 
     Referring now to  FIG. 1 , a schematic of an example of a cloud computing node is shown. Cloud computing node  10  is only one example of a suitable cloud computing node and is not intended to suggest any limitation as to the scope of use or functionality of embodiments of the invention described herein. Regardless, cloud computing node  10  is capable of being implemented and/or performing any of the functionality set forth hereinabove. 
     In cloud computing node  10  there is a computer system/server  12 , which is operational with numerous other general purpose or special purpose computing system environments or configurations. Examples of well-known computing systems, environments, and/or configurations that may be suitable for use with computer system/server  12  include, but are not limited to, personal computer systems, server computer systems, thin clients, thick clients, handheld or laptop devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputer systems, mainframe computer systems, and distributed cloud computing environments that include any of the above systems or devices, and the like. 
     Computer system/server  12  may be described in the general context of computer system executable instructions, such as program modules, being executed by a computer system. Generally, program modules may include routines, programs, objects, components, logic, data structures, and so on that perform particular tasks or implement particular abstract data types. Computer system/server  12  may be practiced in distributed cloud computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed cloud computing environment, program modules may be located in both local and remote computer system storage media including memory storage devices. 
     As shown in  FIG. 1 , computer system/server  12  in cloud computing node  10  is shown in the form of a general-purpose computing device. The components of computer system/server  12  may include, but are not limited to, one or more processors or processing units  16 , a system memory  28 , and a bus  18  that couples various system components including system memory  28  to processor  16  (e.g., CPU). In embodiments, computer system/server  12  includes or communicates with a replication engine  80  as described in greater detail herein. 
     Bus  18  represents one or more of any of several types of bus structures, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. By way of example, and not limitation, such architectures include Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnect (PCI) bus. 
     Computer system/server  12  typically includes a variety of computer system readable media. Such media may be any available media that is accessible by computer system/server  12 , and it includes both volatile and non-volatile media, removable and non-removable media. 
     System memory  28  can include computer system readable media in the form of volatile memory, such as random access memory (RAM)  30  and/or cache memory  32 . Computer system/server  12  may further include other removable/non-removable, volatile/non-volatile computer system storage media. By way of example only, storage system  34  can be provided for reading from and writing to a non-removable, non-volatile magnetic media (not shown and typically called a “hard drive”). Although not shown, a magnetic disk drive for reading from and writing to a removable, non-volatile magnetic disk (e.g., a “floppy disk”), and an optical disk drive for reading from or writing to a removable, non-volatile optical disk such as a CD-ROM, DVD-ROM or other optical media can be provided. In such instances, each can be connected to bus  18  by one or more data media interfaces. As will be further depicted and described below, memory  28  may include at least one program product having a set (e.g., at least one) of program modules that are configured to carry out the functions of embodiments of the invention. 
     Program/utility  40 , having a set (at least one) of program modules  42 , may be stored in memory  28  by way of example, and not limitation, as well as an operating system, one or more application programs, other program modules, and program data. Each of the operating system, one or more application programs, other program modules, and program data or some combination thereof, may include an implementation of a networking environment. Program modules  42  generally carry out the functions and/or methodologies of embodiments of the invention as described herein. For example, some or all of the functions of replication engine  80  may be implemented as one or more program modules  42 . 
     Additionally, replication engine  80  may be implemented as separate dedicated processors or a single or several processors to provide the functionality described herein. The replication engine  80  can be implemented in a processing system for analyzing information associated with third party users, and providing instructions to replicate content of a first user on one or more servers closest to the third party users. More specifically, in embodiments, replication engine  80  performs one or more of the processes described herein in any contemplated combination, including but not limited to determining:
         preferences (profiles) of the user originating the content;   location of third parties in a cloud environment who are previously requested content from the originating user;   usage patterns (e.g., historical patterns) of the third parties or portions thereof;   preferences (profiles) of the third parties requesting content from the user;   types of content that are retrieved by the third parties (i.e., types of files such as video files, pictures, etc.);   the location of servers that are nearest to the third parties; and/or   what information should be replicated to certain servers based on such considerations as load balancing, data type, data size, etc.       

     Based on the above criteria, the processes of the present invention can replicate certain information for storage at certain, predetermined servers. For example, the replicating of the content takes into consideration the closest servers to the third parties wanting to view the posted content, and replicates the content to only such servers. Similarly, based on preferences of the third parties, the content can be replicated to a location of any of the one or more servers nearest to third parties that have a preference indicative of wanting to view the content. Similarly, based on historical usage patterns, the content can be replicated to a location of any of the one or more servers nearest to third parties that have historical usage patterns showing a pattern indicative of wanting to view similar content to the content posted by the user. This same or similar analysis and replication is provided for any of the examples provided herein. 
     Computer system/server  12  may also communicate with one or more external devices  14  such as a keyboard, a pointing device, a display  24 , etc.; one or more devices that enable a user to interact with computer system/server  12 ; and/or any devices (e.g., network card, modem, etc.) that enable computer system/server  12  to communicate with one or more other computing devices. Such communication can occur via Input/Output (I/O) interfaces  22 . Still yet, computer system/server  12  can communicate with one or more networks such as a local area network (LAN), a general wide area network (WAN), and/or a public network (e.g., the Internet) via network adapter  20 . As depicted, network adapter  20  communicates with the other components of computer system/server  12  via bus  18 . It should be understood that although not shown, other hardware and/or software components could be used in conjunction with computer system/server  12 . Examples, include, but are not limited to: microcode, device drivers, redundant processing units, external disk drive arrays, RAID systems, tape drives, and data archival storage systems, etc. 
     Referring now to  FIG. 2 , illustrative cloud computing environment  50  is depicted. As shown, cloud computing environment  50  includes one or more cloud computing nodes  10  with which local computing devices used by cloud consumers, such as, for example, personal digital assistant (PDA) or cellular telephone  54 A, desktop computer  54 B, laptop computer  54 C, and/or automobile computer system  54 N may communicate. Nodes  10  may communicate with one another. They may be grouped (not shown) physically or virtually, in one or more networks, such as Private, Community, Public, or Hybrid clouds as described hereinabove, or a combination thereof. This allows cloud computing environment  50  to offer infrastructure, platforms and/or software as services for which a cloud consumer does not need to maintain resources on a local computing device. It is understood that the types of computing devices  54 A-N shown in  FIG. 2  are intended to be illustrative only and that computing nodes  10  and cloud computing environment  50  can communicate with any type of computerized device over any type of network and/or network addressable connection (e.g., using a web browser). 
     Referring now to  FIG. 3 , a set of functional abstraction layers provided by cloud computing environment  50  ( FIG. 2 ) is shown. It should be understood in advance that the components, layers, and functions shown in  FIG. 3  are intended to be illustrative only and embodiments of the invention are not limited thereto.

     Block Diagrams and Exemplary Operation 
       FIG. 4  depicts a block diagram of a replication engine in a networking environment in accordance with aspects of the invention. More specifically,  FIG. 4  shows a networking environment  75 , which can be any social networking environment or cloud environment, accessible by users  100 ,  100   a ,  100   b , . . .  100   n . In embodiments, user  100  is the originator (poster) or publisher of content, and users  100   a ,  100   b , . . .  100   n  can be friends and/or followers of the user  100 , wishing to obtain or view the content posted by user  100 . The content originating from user  100  can be stored on either a central server  200  or a local server  300 , depending on the rules and configuration of the networking environment  75 . As should be understood by those of skill in the art, the content can be any type of content including, but not limited to, video files, pictures, text, media, or other content, etc. 
     As shown in this exemplary illustration, both central server  200  and local server  300  are in communication with servers  200   a ,  200   b , . . .  200   n . In this way, content can be passed between and stored on any combination of servers. In this exemplary configuration, central server  200  includes replication engine  80 ; although, the present invention contemplates any combination of servers also including the replication engine  80 . 
     By using replication engine  80  in accordance with aspects of the present invention, information stored on any of the servers can be shared or replicated on any combination of the servers taking into consideration the different criteria set forth herein. For example, content stored on local server  300  can be replicated and stored on any of the servers  200   a ,  200   b , . . .  200   n , in accordance with aspects of the present invention. More specifically, in this exemplary illustration, content originating from user  100  can be uploaded to either of central server  200  or local server  300 , depending on the particular rules of environment  75 . In any scenario, upon receipt of the content (from user  100 ), replication engine  80  will make a determination (analysis) as to which servers  200   a ,  200   b , . . .  200   n  will receive replicated content, originating from user  100 . This determination can be made based on many different combinations of factors including, for example:
         which users  100   a ,  100   b , . . .  100   n  are friends and/or followers of user  100 ;   the physical location of the friends and/or followers and a nearest server  200   a ,  200   b , . . .  200   n  to the physical location of the friends and/or followers;   the type of content which is being published by the originating user, e.g., media, etc.;   the type of content which has previously been reviewed and/or requested by the friends and/or followers (or other preferences of the friends and/or followers);   historical usage patterns of the friends and/or followers;   whether certain thresholds have been met, e.g., a predetermined number or percentage of friends and/or followers are located at a certain location, near a certain server, access certain types of information, etc.; and/or   other types of quantitative information such as, for example, quality of servers, load balancing issues, quality of content for each server, etc.       

     In the scenario that replication engine  80  is resident on central server  200 , local server  300  will query central server  200 , i.e., replication engine  80 , in order to prompt replication engine  80  to provide the above analysis. Upon such analysis/determination, replication engine  80  will direct either central server  200  or local server  300  to replicate the appropriate content and provide such content to the appropriate server  200   a ,  200   b , . . .  200   n . The content can be saved on any of the servers, depending on the specific analyzed criteria and subsequent rules. In this way, the content does not have be replicated and stored on each and every server, thus more efficiently utilizing current resources. 
       FIGS. 5 a  and 5 b    show a visualization of interactions between servers and clusters of friends and/or followers, in accordance with aspects of the preset invention. In particular,  FIGS. 5 a  and 5 b    show a visualization of several clusters of users (e.g., friends and/or followers)  400   a ,  400   b , . . .  400   n , interacting with one another and with respective servers  200   a ,  200   b , . . .  200   n  within a networking environment.  FIGS. 5 a  and 5 b    also show a central server  200  and a local server  300 . In this example, content from user  100  can be stored on local server  300 . The local server  300  can query the central server  200  to determine replication and storage of content, e.g., on servers  200   a ,  200   b , . . .  200   n.    
     By way of illustrative non-limiting example, the replication engine can determine that there is a heavy concentration of users  400   n , near server  200   n . The replication engine can then direct that the replicated content be stored on server  200   n . In another illustrative non-limiting example, the replication engine can determine that the concentration of users  400   b  and  400   n  are over a threshold number or percentage, e.g.,  50  users, and then direct the replicated content to be stored on servers  200   b  and  200   n , which have been determined to be the closest servers to users  400   b  and  400   n . In yet another illustrative non-limiting example, the replication engine can determine that the users  400   a  and  400   b  have a history of viewing, e.g., media data, from the user  100 , and request replication of only media data of the user  100  to be stored on servers  200   a  and  200   b . Of course, other examples are also contemplated by the present invention, including, use of historical usage patterns and any combination of the above examples, etc. 
     Flow Diagrams 
       FIGS. 6 and 7  show exemplary flows for performing aspects of the present invention. The steps of  FIGS. 6 and 7  may be implemented in any of the environments of  FIGS. 1-5 , for example. The flowcharts and block diagrams in the Figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present invention. In this regard, each block in the flowcharts or block diagrams may represent a module, segment, or portion of code, which includes one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams and/or flowchart illustration, and combinations of blocks in the block diagrams and/or flowchart illustration, can be implemented by special purpose hardware-based systems that perform the specified functions or acts, or combinations of special purpose hardware and computer instructions. 
     Furthermore, the invention can take the form of a computer program product accessible from a computer-usable or computer-readable medium providing program code for use by or in connection with a computer or any instruction execution system. The software and/or computer program product can be implemented in any one or more of the environments of  FIGS. 1-5 . 
       FIG. 6  depicts an exemplary flow for a process in accordance with aspects of the present invention. At step  600 , a user will connect to a networking environment, e.g., local server on the networking environment. At step  605 , the content will be uploaded to the local server or a central server, depending on the configuration of the networking environment. For example, the central server can be a local server, which serves as a storage repository of information for the user. In any scenario, at step  610 , the replication engine is queried to analyze which servers should receive replicated content for storage, to be later retrieved by a friend and/or follower of the user. At step  615 , the replication engine can make an analysis based one or a combination of several criteria, including but not limited to:
         preferences (profiles) of the user originating the content;   preferences (profiles) of the third parties requesting content from the user. These preferences (profiles) may be the type of data they like to view, the size of the data they prefer to download, etc., any of which can be associated with the user or other third parties, or friends of friends, etc.;   location of third parties in a cloud environment who are associated with an originator of content, e.g., friends and/or followers on a social network, and the location of servers nearest to such third parties;   usage patterns of the third parties or portions thereof;   types of content that are retrieved by the third parties (i.e., types of files such as video files, pictures, etc.);
           whether certain thresholds have been met, e.g., a certain amount or percentage of third parties are at a certain location; and/or   what content should be replicated to certain servers based on, for example, load balancing considerations, data type, data size, etc.   
               

     At step  620 , based on the above criteria, the processes of the present invention can replicate certain information for storage at certain, predetermined servers. For example, the replicating of the content comprises replicating the content on one or more servers closest to a location of any of the one or more third parties that have a preference indicative of wanting to view the content. Similarly, the replication of the content comprises replicating the content on one or more servers closest to a location of any of the one or more third parties that have historical usage patterns showing a pattern indicative of wanting to view similar content to the content. This same or similar analysis and replication is provided for any of the examples provided herein, based on the third party information. 
     At step  625 , the information obtained during the analysis can be saved in a central storage, to be used at a later time for further analysis, e.g., replication and storage of content. For example, the preferences (profiles) of the originating user or the friends and/or followers can be saved in a central storage so that this same information does not need to be gathered again at a later time. The processes of the present invention can also use this saved information to perform historic usage pattern analysis, more readily determine locations of the originating user or the friends and/or followers and respective servers, etc. 
       FIG. 7  depicts an exemplary flow for a process in accordance with aspects of the present invention. At step  700 , a network provider (e.g., system or process) obtains information on the users and followers and/or friends associated with the users. At step  705 , a user publishes content on their social network. This published content can include, amongst other information, status update, file information, media type, etc. At step  710 , the system receives the published content by the user and may review this information for the type of information, the size of the information, etc. 
     At step  715 , the system analyzes the followers and/or friends of the user. This may include, for example, their location, preferences and/or profiles, usage patterns and types of content typically viewed from the user, etc. At step  720 , the system determines the portion of followers and/or friends of that user by location. For example, the social network provider system determines how many users are located near each local server and whether certain thresholds are met. Optionally, at step  725 , historical access patterns may also be gathered, e.g., while most of a user&#39;s followers are in location #1, more users in location #2 play movies posted by the user. By way of another example, depending on the context of the message certain users tend to be more likely to read the content, e.g., content about vacations, movies, and other events. 
     At step  730 , the system determines whether the portion of followers and/or friends for each location, as determined from step  720 , meets criteria of replicating content. For example, the criteria may be a threshold of a percentage of followers being at a certain location or a number of followers above a certain threshold, e.g., 100 are at a certain location. If the threshold is not met, then at step  735 , the process ends. However, if the threshold is met, at step  740 , the system replicates the content to those servers (datacenters) in the qualified location or location closest to that qualified location. At step  745 , the followers and friends of the user can then access the content (or the system publishes the aggregated content of each user&#39;s followers/friends) at their local or nearest server. Since the content is being served by a closer datacenter, the content is likely to be displayed faster or at a higher quality. Accordingly, the processes and systems of the present invention help not only performance issues, but also reduce the replication of content.
