## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims priority benefit of, and is a continuation of, U.S. nonprovisional application Ser. No. 13/831,386 filed Mar. 14, 2013, entitled “Compute-Centric Object Stores and Methods of Use,” which is incorporated by reference in its entirety herein.


FIELD OF THE PRESENT TECHNOLOGY
The present technology relates generally to compute-centric object stores and methods of using the same. The compute-centric object stores of the present technology provide multi-tenancy by assigning guest virtual operating system containers to a plurality of users (e.g., tenants). The virtual operating system containers are assigned and managed by a global or “host” operating system kernel that operates on a physical machine.
BACKGROUND
Various methods and systems for providing multitenant computing systems, such as cloud computing, have been attempted. In general, a cloud-based computing environment is a resource that typically combines the computational power of a large model of processors and/or that combines the storage capacity of a large model of computer memories or storage devices. For example, systems that provide a cloud resource may be utilized exclusively by their owners; or such systems may be accessible to outside users who deploy applications within the computing infrastructure to obtain the benefit of large computational or storage resources.
The cloud may be formed, for example, by a network of servers with each server (or at least a plurality thereof) providing processor and/or storage resources. These servers may manage workloads provided by multiple users (e.g., cloud resource consumers or other users). Typically, each user places workload demands upon the cloud that vary in real-time, sometimes dramatically. The nature and extent of these variations typically depend on the type of business associated with the user.
Oftentimes, these cloud computing systems leverage virtual machines for their users. A virtual machine (“VM”) is an emulation of a real-world computing system. Often, the virtual machine provides a user with one or more different operating systems than the operating system of the local machine (“host”) that is running the virtual machine. The VM provides a complete system platform that provides the one or more operating systems. The VM is typically managed by a hypervisor that mediates computing resources of the host machine for use by the VM via hardware emulation. The use of hardware emulation is often deleterious to VM performance and efficient utilization of physical resources and, in turn, reduces the number of VMs that may run on a given host machine. Additionally, as the number of VMs on a host machine increases and they begin to operate concurrently, the hypervisor must coordinate the varying workloads of the VMs to prevent instability

DESCRIPTION OF EXEMPLARY EMBODIMENTS
While this technology is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail several specific embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the technology and is not intended to limit the technology to the embodiments illustrated.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present technology. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
It will be understood that like or analogous elements and/or components, referred to herein, may be identified throughout the drawings with like reference characters. It will be further understood that several of the figures are merely schematic representations of the present technology. As such, some of the components may have been distorted from their actual scale for pictorial clarity.
FIG. 1 is a block diagram of an exemplary architecture 100 in which embodiments of the present technology may be practiced. The architecture 100 comprises a plurality of client devices 105A-N that communicatively couple with a compute-centric object store system, hereinafter “system 110.” It will be understood that the architecture 100 may include a plurality of systems, such as system 110. For the sake of brevity and clarity, a detailed description of an exemplary system 110 will be provided below, although the features of the system 110 apply equally to all of the plurality of systems. The plurality of client devices 105A-N may communicatively couple with the system 110 via any one or combination of a number of private and/or public networks, such as the Internet. According to some embodiments, the client devices 105A-N may submit requests or jobs to a network service 110B, which is a constituent part of the system 110. In some instances, the network service 110E evaluates request received from users to determine one or more physical nodes that comprise objects that correspond to the request.
In general, the system 110 comprises an object store 110A that provides “compute” as a first class citizen of an object store 110A. More specifically, compute operations (e.g., instructing the system to compute on objects in the object store) of the present technology resemble a top-level API function, similar to processes like storing or fetching objects in the object store 110A.
It will be understood that the terms “object store” comprise a network service for storing unstructured, arbitrary-sized chunks of data (objects). It will be further understood that the object store may not support modifications to existing objects, but supports full object replacement operations, although systems that support both object modification and full object replacement operations may also utilize the features of the present technology to perform compute operations directly on (e.g., in-situ) objects within the object store.
In some embodiments, the system 110 may be configured to receive a request to perform a compute operation on at least a portion of an object store, from a first user. Again, the user may be associated with one of the client devices. The request identifies parameters of the compute operation as well as objects against which the compute operation is executed.
In some instances, the system 110 may assign virtual operating system containers to a user, based upon a request. The system 110 may map objects to the containers that are associated with the user. Typically, these objects are identified by the user in the request. A virtual operating system container performs the compute operation on an object according to the identified parameters of the request. The system 110 may then clear the virtual operating system containers and return the virtual operating system containers to a pool of virtual operating system containers. Additional aspects of the system 110 will be described in greater detail below.
It will be understood that a compute-centric object store may be created to operate without the user of virtual operating system (global kernel) or virtual operating system containers. While such an object store would provide advantages such as in-situ computation of data (where objects are processed directly on the object store), the object store may not isolate tenants in the similarly to systems that utilize a virtual operating system and/or virtual operating system containers.
In these instances, the compute-centric object store may be configured to receiving a request to perform a compute operation on at least a portion of an object store from a first user via a network service, the request identifying parameters of the compute operation. The object store may also execute an operating system process for the objects identified in the request. The operating system process may perform the compute operation on the object according to the identified parameters of the request. Additionally, once the compute operation has been executed, the operating system process may be terminated by the virtual operating system.
The terms in-situ computation will be understood to include the execution of compute operations against objects in an object store, where the objects not moved or copied from or within the object store.
In some embodiments, the system 110 is comprised of a hardware layer 115 that provides a logical interface with at least one or more processors and a memory which stores logic that is executed by the one or more processors. Generally, the hardware layer 115 controls one or more of the hardware components of a computing system, such as the computing system 600 of FIG. 6, which will be described in greater detail below. By way of non-limiting example, the hardware layer 115 may manage the hardware components of a server blade or another similar device. The hardware layer 115 provides access to the physical hardware that services a global operating system kernel 120 that cooperates with the hardware layer 115. The global operating system kernel 120 may also be referred to as a host operating system kernel.
Generally, the global operating system kernel 120 is configured to administer and manage a pool of guest virtual operating system containers, such as containers 125A-N. The containers 125A-N may operate on a distributed object store in a multitenant manner, where multiple containers can operate on the same object store simultaneously. It will be understood that each user is assigned container from the pool, on an as-needed basis. When a container is applied to an object store the container is referred to as a tenant.
According to some embodiments, the system kernel 120 may be utilized to setup the pool of guest virtual operating system containers. The system kernel 120 may also be configured to provide a command line interpreter interface that allows users to request jobs, execute other operating system implemented applications, and interact with a virtual operating system in a manner that is substantially indistinguishable relative to an operating system executing on a bare metal device.
Generally, a job may be input by a user via a command line interpreter, such as a Unix shell terminal. More specifically, the user may express a computation using the same language as the language used by a Unix shell terminal. The actual request is submitted to the network service 110B. Indeed, a request may be submitted as an HTTP request to the network service 110B. The body of the request describes the computation to perform in terms of what commands are input into the command line interpreter, which is running within a container. Contrastingly systems that utilize multiple VMs that each comprises an operating system kernel, which are managed by a hypervisor, often require users to construct complex programs or scripts to perform compute operations. Compute operations for traditional VM systems require complex programming due to a complex framework that is used by the hypervisor to coordinate hardware emulation for each of the VMs.
Using the command line interpreter interface, the user may specify one or more desired compute operations that are to be executed against objects (such as object 130) within an object store 110A (see FIG. 3). It is noteworthy that the object store 110A may include, for example, a local or distributed object store that maintains contiguous blobs, blocks, or chunks of data. It will be understood that the objects stored in the object store 110A are complete objects, such as files or other similar data structures. Moreover, the compute operations executed against the object store 110A may be performed in such a way that partial stores of data are avoided.
In order to perform compute operations on objects for multiple users, the system kernel 120 may collocate containers 125A-N onto the object store 110A, and execute the containers 125A-N simultaneously. In FIG. 3, a plurality of containers, such as container 125A has been placed onto each of a plurality of objects within the object store 110A. Thus, a virtual operating system container is assigned to each of the plurality of objects specified in the user request. Most frequently, the assignment of a single container to a single object occurs when the system executes a “map” phase operation. The details of map and reduce phases provide by the system 110 will be described in greater detail below.
Broadly speaking, a virtual operating system container may be a lightweight virtualization solution offering a complete and secure user environment that operates on a single global kernel (system kernel 120), providing performance characteristics that are similar to operating systems that operate on bare metal devices. That is, a virtual machine operates on emulated hardware and is subject to control by a hypervisor, which produces computing inefficiencies. A virtual operating system container may operate without the computing inefficiencies of a typical virtual machine.
In some instances, the system kernel 120 may utilize a KVM (Kernel Virtual Machine) that improves the efficiency of the a virtual operating system, such as the global operating system kernel, by leveraging CPU virtualization extensions to eliminate a substantial majority of the binary translation (i.e., hardware emulation) that are frequently required by VMs.
Turning to FIG. 2, an exemplary virtual operating system container 125A (FIG. 1) is shown as comprising a quick emulation layer (QEMU) 135, a virtual guest operating system 140, and a compute application 145 that is managed by the virtual guest operating system 140. The QEMU 135 provides hardware emulation and is also VMM (virtual machine monitor). It is noteworthy that in some embodiments the QEMU 135 is not a strict hypervisor layer, but rather each QEMU 135 may be independent in some exemplary embodiments. That is, there may be one QEMU 135 one per container instead of a single QEMU 135 supporting several VMs. Advantageously, the operations of both a VM and a VMM may be combined into the QEMU 135.
According to some embodiments, the compute application 145 that is executed may include a primitive O/S compute operation. Exemplary compute operations may include operating system primitive operations, such as query, word count, send, receive, and so forth. Additionally, the operations may comprise more sophisticated operations, such as operations that include audio or video transcoding. Additionally, in some instances, users may store programs or applications in the object store itself. Users may then execute the programs as a part of a compute operation.
In some instances the compute operations may include one or more phases such as a map phase, followed by a reduce phase. Generally, a map phase may include an operation that is executed against each of a plurality of objects individually, by a plurality of containers. In some instances, a unique container is assigned to each object that is to be processed.
In contrast, a reduce phase may be executed by a single container against a plurality of objects in a batch manner. Using an example such as word count, it will be assumed that the objects of the object store 135 may comprise text files. The application 145 may execute a map phase to count the words in each of the text files. The output of the application 145 may be stored in a plurality of output objects that are stored in the object store 135. A compute application 145 of another container may execute a reduce phase that sums the output objects of the map phase and generates a word count for all objects within the object store 135.
It will be understood that the system kernel 120 may schedule and coordinate various compute operations (and phases) performed by the compute applications 145 of all containers. In sum, the system kernel 120 may act similarly to a hypervisor that manages the compute operations of the various active containers. Based upon the request input by the user, the system kernel 120 may instruct the containers to perform a series of map functions, as well as a reduce functions. The map and reduce functions may be coordinated to produce the desired output specified in the request.
Turning to FIG. 3, after receiving a request from a user, the system kernel 120 may select a first set of containers, which includes container 125A from the pool of containers. This container 125A is assigned to a user. In response to receiving a request from a second user, the system kernel 120 may also select a second set of containers from the pool of containers.
Based upon the request received from the first tenant, the system kernel 120 may map the first set of containers to a plurality of objects, such as object 130, stored in the object store 110A. Likewise, the system kernel 120 may map a second set of containers to a plurality of different objects stored in the object store 110A for the second user. The objects and containers for the first user may be referred to as a compute zone of the first user, while the objects mapped to the container 125N may be referred to as a compute zone of the second user. The maintenance of compute zones allows the system kernel 120 to provide multitenant access to the object store 110A, even when the first and second users are potentially adversarial. For example, the first and second users may be commercial competitors. For security, the system kernel 120 maintains compute zones in order to balkanize object storage and prevent access to objects of other users. Additionally, the balkanization of object storage also ensures fair distribution of resources between users.
It will be understood that the system kernel 120 may maintain as many containers and compute zones as allowed by the processor(s) of the hardware layer 115. Additionally, the system kernel 120 assigns a container to a user on an as-needed basis, meaning that containers may not be assigned permanently to a user, which would result in a monopolization of resources when the user is not performing compute operations.
FIG. 4 illustrates the placement of the container 125A onto the data store 110A. It is understood that the container 125A encircles a plurality of objects in the data store 110A. This mapping of multiple object to a single container would be commonly seen in a reduce phase, where the container is performing a concatenating or summation process on the outputs of individual containers, such as the containers shown in FIG. 3.
Additionally, because the container is placed onto the object store, the system kernel 120 need not transfer objects from the object store 110A into the container for processing in some exemplary embodiments. Advantageously, the container operates directly on the objects of the object store 110A.
According to some embodiments, the containers 125A-N managed by the system kernel 120 are empty when the containers 125A-N are in the pool. After objects are mapped to the container, compute operations may be executed by the container on the objects, and a desired output is generated, the system kernel 120 may clear the container and return the container to the pool.
In some instances, the system kernel 120 may not generate containers until a request is received from a user. That is, the system kernel 120 may “spin up” or launch containers when a request is received from the user. This allows for minimum impact to the bare metal resources, such as the CPU, as the system kernel 120 need not even maintain a pool of virtual operating system containers, which are awaiting user requests. That is, maintaining a pool of containers requires CPU and memory resources. When the compute operations have been completed, the system kernel 120 may terminate the containers, rather than clearing the containers and returning the containers to a pool.
FIG. 5A is a flowchart of an exemplary method 500 for providing a compute-centric object store. The method may comprise a step 510 of generating a pool of empty virtual operating system containers. These virtual operating system containers may be constructed as described above and are made available to a plurality of users.
The method comprises a step 510 receiving a request to perform a compute operation on at least a portion of an object store from a user. As mentioned above, the request identifies parameters of the compute operation and objects against which the compute operation is executed.
The method may also comprise a step 515 of assigning virtual operating system containers to the user. In some instances, the assigning of a virtual operating system may include a step of making a read-only instantiation of the object available to applications running inside the virtual operating system container. Using the parameters defined in the request, the system may inform compute applications of the containers in order to establish a schedule of operations that are to be performed on the objects specified in the request. The method also includes a step 520 of mapping the objects in the request to the containers.
Next, the method may include a step of performing the compute operation on the objects according to the identified parameters of the request, as well as a step 525 of storing the output of the compute operation in the object store. Additionally, the method may include a step 530 of clearing the virtual operating system containers, as well as a step 535 of returning the containers back to the pool.
It is noteworthy that the method may be repeated for multiple users, allowing for a plurality of containers to be collocated on the objects store and performing compute operations on the data store, even in an overlapping manner (e.g., multi-tenancy).
FIG. 5B is a flowchart of an exemplary method 540 for executing compute operations within a compute-centric object store. The method may include a step 545 of receiving a request to perform a compute operation on at least a portion of an object store from a first user via a network service. The request identifying parameters of a desired compute operation that is to be executed against an object(s) in the object store.
The method may also include a step 550 of executing an operating system process for the objects identified in the request via a virtual operating system, as well as a step 555 where the operating system process is performing the compute operation on the object according to the identified parameters of the request. Also, the method includes a step 560 of terminating the operating system process via the virtual operating system.
