Abstract:
A computer-based analysis of an enterprise computer system is utilized to remove bottlenecks that cause the enterprise computer system to operate in a non-optimal or risky manner. Contents of e-mails are examined to identify bottlenecks in the enterprise computer system. Upon identifying the bottlenecks, the enterprise computer system is simulated, and simulations of replacement components, which the computer-based analysis has deemed appropriate for curing the bottlenecks, are installed in the simulated system. If the computer simulation with the replacement components cures the bottlenecks and causes no new problems for the enterprise computer system, then corresponding actual replacement components are installed in the enterprise computer system.

Description:
The present application is a continuation of U.S. patent application Ser. No. 12/169,749, filed on Jul. 9, 2008, and entitled, “Modifying an Information Technology Architecture Framework,” which is herein incorporated by reference in its entirety. 
    
    
     BACKGROUND 
     The present disclosure relates in general to the field of computers, and more particularly to Information Technology (IT) architecture framework. Still more particularly, the present disclosure relates to improving an architecture framework using a “bottom up” architecture improvement methodology. 
     An enterprise Information Technology (IT) architecture (“architecture”) is defined as a combination of hardware and software that is used to perform text, data, website, multimedia and other computer related processing for an enterprise. An enterprise IT architecture framework (“framework”) is defined as a model (i.e., a “blueprint”) of the enterprise IT architecture. Thus, the framework describes a high level view of the architecture, and the architecture describes components of an IT system in finer detail. 
     The interplay between an architecture and a framework (a.k.a., “architecture framework”) leads to problems when attempting to improve an existing IT system. That is, systems engineers typically choose between evaluating and improving either the architecture or the framework, but do not contemplate an interaction between the two. 
     SUMMARY 
     A computer-based analysis of an enterprise computer system is utilized to remove bottlenecks that cause the enterprise computer system to operate in a non-optimal or risky manner. Contents of e-mails are examined to identify bottlenecks in the enterprise computer system. Upon identifying the bottlenecks, the enterprise computer system is simulated, and simulations of replacement components, which the computer-based analysis has deemed appropriate for curing the bottlenecks, are installed in the simulated system. If the computer simulation with the replacement components cures the bottlenecks and causes no new problems for the enterprise computer system, then corresponding actual replacement components are installed in the enterprise computer system. 
     The above as well as additional objectives, features, and advantages of the present invention will become apparent in the following detailed written description.

     DETAILED DESCRIPTION 
     As will be appreciated by one skilled in the art, the present invention may be embodied as a method, system, or computer program product. Accordingly, the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, the present invention may take the form of a computer program product on a computer-usable storage medium having computer-usable program code embodied in the medium. 
     Any suitable computer usable or computer readable medium may be utilized. The computer-usable or computer-readable medium may be for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, device, or propagation medium. More specific examples (a non-exhaustive list) of the computer-readable medium would include the following: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a transmission media such as those supporting the Internet or an intranet, or a magnetic storage device. Note that the computer-usable or computer-readable medium could even be paper or another suitable medium upon which the program is printed, as the program can be electronically captured, via, for instance, optical scanning of the paper or other medium, then compiled, interpreted, or otherwise processed in a suitable manner, if necessary, and then stored in a computer memory. In the context of this document, a computer-usable or computer-readable medium may be any medium that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The computer-usable medium may include a propagated data signal with the computer-usable program code embodied therewith, either in baseband or as part of a carrier wave. The computer usable program code may be transmitted using any appropriate medium, including but not limited to the Internet, wireline, optical fiber cable, RF, etc. 
     Computer program code for carrying out operations of the present invention may be written in an object oriented programming language such as Java® (Java® is a trademark or registered trademark of Sun Microsystems, Inc. in the United States and other countries), Smalltalk, C++ or the like. However, the computer program code for carrying out operations of the present invention may also be written in conventional procedural programming languages, such as the “C” programming language or similar programming languages. The program code may execute entirely on the user&#39;s computer, partly on the user&#39;s computer, as a stand-alone software package, partly on the user&#39;s computer and partly on a remote computer or entirely on the remote computer or server. In the latter scenario, the remote computer may be connected to the user&#39;s computer through a local area network (LAN) or a wide area network (WAN), or the connection may be made to an external computer (for example, through the Internet using an Internet Service Provider). 
     The present invention is described below with reference to flowchart illustrations and/or block diagrams of methods, apparatuses (systems) and computer program products according to embodiments of the invention. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. 
     These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function/act specified in the flowchart and/or block diagram block or blocks. 
     The computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions/acts specified in the flowchart and/or block diagram block or blocks. 
     With reference now to  FIG. 1 , there is depicted a block diagram of an exemplary computer  100 , with which the present invention may be utilized. Computer  100  includes a processor unit  104  that is coupled to a system bus  106 . A video adapter  108 , which drives/supports a display  110 , is also coupled to system bus  106 . System bus  106  is coupled via a bus bridge  112  to an Input/Output (I/O) bus  114 . An I/O interface  116  is coupled to I/O bus  114 . I/O interface  116  affords communication with various I/O devices, including a keyboard  118 , a mouse  120 , a Compact Disk-Read Only Memory (CD-ROM) drive  122 , and a flash memory drive  126 . The format of the ports connected to I/O interface  116  may be any known to those skilled in the art of computer architecture, including but not limited to Universal Serial Bus (USB) ports. 
     Computer  100  is able to communicate with a server  150  via a network  128  using a network interface  130 , which is coupled to system bus  106 . Network  128  may be an external network such as the Internet, or an internal network such as an Ethernet or a Virtual Private Network (VPN). 
     A hard drive interface  132  is also coupled to system bus  106 . Hard drive interface  132  interfaces with a hard drive  134 . In one embodiment, hard drive  134  populates a system memory  136 , which is also coupled to system bus  106 . System memory  136  is defined as a lowest level of volatile memory in computer  100 . This volatile memory may include additional higher levels of volatile memory (not shown), including, but not limited to, cache memory, registers, and buffers. Code that populates system memory  136  includes an operating system (OS)  138  and application programs  144 . 
     OS  138  includes a shell  140 , for providing transparent user access to resources such as application programs  144 . Generally, shell  140  (as it is called in UNIX®—UNIX is a registered trademark of The Open Group in the United States and other countries) is a program that provides an interpreter and an interface between the user and the operating system. Shell  140  provides a system prompt, interprets commands entered by keyboard  118 , mouse  120 , or other user input media, and sends the interpreted command(s) to the appropriate lower levels of the operating system (e.g., kernel  142 ) for processing. As depicted, OS  138  also includes kernel  142 , which includes lower levels of functionality for OS  138 . Kernel  142  provides essential services required by other parts of OS  138  and application programs  144 . The services provided by kernel  142  include memory management, process and task management, disk management, and I/O device management. Note that UNIX® is merely an exemplary OS that can be utilized by the presently described computer  100 , which may utilize any other appropriate OS, including, but not limited to, Windows® (Windows® is a registered trademark of Microsoft, Inc. in the United States and other countries), Linux® (Linux® is a registered trademark of Linus Torvalds in the United States and other countries), etc. 
     Application programs  144  include a browser  146 . Browser  146  includes program modules and instructions enabling a World Wide Web (WWW) client (i.e., computer  100 ) to send and receive network messages to the Internet. Computer  100  may utilize HyperText Transfer Protocol (HTTP) messaging to enable communication with server  150 . Application programs  144  in system memory  136  also include an Enterprise Computer System Optimizer (ECSO)  148 . ECSO  148  is software that performs the functions described in the figures below. In one embodiment, computer  100  is able to download ECSO  148  from service provider server  150 , including in an “on demand” basis. In another embodiment, service provider server  150  performs all of the functions associated with the present invention (including execution of ECSO  148 ), thus freeing computer  100  from using its own resources. 
     Note that ECSO  148  is able to monitor activities, as described below, or an Enterprise Computer System (ECS)  152 , which is coupled to computer  100  either directly via the network interface  130 , or indirectly via the network  128 . ECS  152  is preferably an enterprise system that is made up of multiple computers, servers, storage devices, printers, etc. that utilize some or all of the architecture shown for computer  100 . Thus, computer  100  functions as a monitoring computer that oversees the ECS  152  in a manner described below, and then creates an optimized architecture framework for ECS  152  using replacement components in the architecture of ECS  152 . 
     The hardware elements depicted in computer  100  are not intended to be exhaustive, but rather represent and/or highlight certain components that may be utilized to practice the present invention. For instance, computer  100  may include printers, alternate memory storage devices such as magnetic cassettes, Digital Versatile Disks (DVDs), Bernoulli cartridges, and the like. These and other variations are intended to be within the spirit and scope of the present invention. 
     With reference now to  FIG. 2 , a high-level flow chart of exemplary steps taken to optimize an enterprise computer system in order to create an improved architecture framework is presented. As depicted in initial block  202 , the process may begin by assigning team members to enterprise architecture Focus Areas (FAs). These FAs focus on business pain points, which have been previously identified, by a computer such as computer  100 , for an enterprise computer system such as ECS  152  shown in  FIG. 1 . Pain points are defined as conditions that lead to a reduced efficiency of total operations of the ECS  152 . Examples of such pain points in ECS  152  that are identified computer  100  include, but are not limited to, the following: 
     Computer repair work orders—ECSO  148 , shown in  FIG. 1 , may identify a history of repair work orders for elements within ECS  152 . This history may be stored in a database within computer  100 , and may be identified by flags in the database. 
     Load balancing—ECSO  148  may also identify excessive or improper load balancing between components within ECS  152 . For example, if a first server has to help a second server beyond some pre-defined limit set by ECSO  148 , then this indicates that there is some type of operational deficiency in the second server, which is not able to handle its own assigned workload. 
     Bottlenecks—ECSO  148  may also identify work and/or data transmission bottlenecks between components of ECS  152 . For example, ECSO  148  may monitor one or more processors found in ECS  152  that have a recorded history of stalls that have occurred due to waiting for processing results from a particular processor that is repeatedly slow to handle requested jobs, such as a co-processing job. Similarly, a particular piece of software may be identified in ECS  152  that has a history of causing other software components (applications, routines, etc.) to stall. For example, web pages running in ECS  152  may have to wait repeatedly for a media file that is slow to upload into the web pages. 
     E-mail failures—ECSO  148  may also identify e-mail failures that repeatedly occur within ECS  152 . ECSO  148  can identify the root cause of such failures (e.g., mistyping of e-mail addresses by users, exceeding daily e-mail usage limits set by a service, exceeding attachment limits for attachments to an e-mail, hardware failures in an e-mail server, etc.) by the use of flags, error messages, etc. that are interpreted by ECSO  148 . 
     Unauthorized computer usage—ECSO  148  can monitor for and detect improper computer usage, such as downloading games, video clips, etc. that cause the system to slow down, using resources of ECS  152  for personal use, including Voice Over IP (VoIP) phone calls, etc. 
     Besides the pain points that are identified by computer  100 , human team members in the FAs can also identify pain points, which are then input into computer  100 , which utilizes software logic to create optimization solutions. Examples of pain points identified by team members include, but are not limited to, the following: 
     Building layout faults—These problems include those identified by a risk analysis performed by the team members. Such a risk analysis may identify an improper design and/or layout of a building in which employees of the enterprise utilize computer equipment. This improper design/layout may lead to supply deliveries of physical products (i.e., paper, drinks, etc.) being dropped against sensitive computer equipment; botanical plants being positioned over sensitive computer equipment, such that watering the plant may result in water overflow that damages the equipment; sensitive equipment being stored in a basement that is prone to flooding; etc. 
     Language, environmental and cultural issues—Besides issues such as language barriers (e.g., supplying an English QWERTY keyboard to a user who writes in a Cyrillic-based language), other cultural, language and environmental issues may also arise, particularly in third world countries. For example, power outages in third world countries are often common. If unaddressed (e.g., by a long-term uninterruptable power supply (UPS) such as a diesel-powered generator), these power outages may cause repeated problems. Similarly, a third-world environment may be particularly sandy, dusty, humid, etc., which will impact on computer components if not protected against. Furthermore, citizens of any country may adhere to religious/cultural practices that may raise a conflict with how a computer system is to be used/maintained, such as prohibitions against working at certain times or on certain days, etc. 
     Note that the team, which is referenced in block  202 , is made up of multiple team members, which have been qualified by ECSO  148  according to each person&#39;s experience, training and performance grades. Note again, however, that while team members performs some of the overseeing duties required by the present invention, most of the processes must be performed by a computer, due to a requirement to automatically process and analyze pain point signals (e.g., flags), process extremely complex and numerous signals from a large number of components in the ECS  152  being evaluated, etc. 
     With reference to block  204  of  FIG. 2 , the computer  100  (and, alternatively, members of the team) then researches and documents the pain points of the system (including, but not limited to, those pain points described above). For example, the computer  100  can crawl databases, e-mails, alarm points, etc. to quickly identify all components that are underperforming or nonperforming. This process leads to a pinpoint identification of which component within the ECS  152  is causing or experiencing (or may cause or experience in the future) the pain point(s) identified in the process depicted in block  204 . 
     As depicted in block  206 , once the candidate components that are causing/experiencing or may in the future cause/experience the pain points are identified, a simulation of the ECS  152  is launched using simulated replacement components for the candidate components that have been identified as pain producers/experiencers. This simulation is a software simulation of all components, both hardware and software, found in the ECS  152 . 
     As depicted in block  208 , the computer and/or team then review the software simulation to determine if the pain points have been removed. This review includes using new components, preferably in a hands-on manner by team members if technically feasible, in order to confirm that the new components do not violate any concern or cause any of the pain points described above. 
     After the team and computer  100  fine tune the selection process for the new components (block  210 ), actual hardware/software that was modeled by the simulated replacement components are then installed into the physical ECS  152 . At that point (block  212 ), the computer  100  finalizes the replacement components by relabeling them and their subcomponents (which may not be new). Computer  100  then monitors the ECS  152  to determine if any new pain points (which were not previously recognized and/or defined) have occurred, or if any old pain points still remain in the originally troublesome component or any other component (which was previously not experiencing pain). 
     Thereafter, computer  100  creates an improved framework for ECS  152  that uses the new components. That is, by populating an original architecture framework with the new components, a new architecture framework is defined according to the functionality of, features of and new interrelationships created by the new components. 
     As described herein, the present invention defines a novel approach to defining an improved framework using a “bottom up” approach, in which the new components in the architecture set the definition for the new architecture framework. This allows a monitoring computer to automatically upgrade the architecture framework of a system that is under review, thus allowing a system engineer to focus on root causes of pain points and to be involved in the selection of needed upgrade components.
