System Integration

System integration is the bringing together of the component subsystems into one system and ensuring that the subsystems function together as a system. In information technology, systems integration is the process of linking together different computing systems and software applications physically or functionally. The system integrator brings together discrete systems utilizing a variety of techniques such as computer networking, enterprise application integration, business process management or manual programming.

A system is an aggregation of subsystems cooperating so that the system is able to deliver the over-arching functionality. System integration involves integrating existing (often disparate) subsystems. The subsystems will have interfaces. Integration involves joining the subsystems together by "gluing" their interfaces together. If the interfaces "glue" directly interlock, the "glue" between them can provide the required mappings. System integration is about determining the required "glue".

System integration is also about value-adding to the system, capabilities that are possible because of interactions between subsystems.

In today's connected world, the role of system integration engineers is becoming more and more important: more and more systems are designed to connect together, both within the system under construction and to systems that are already deployed.

Thin Client

In place of a PC, Thin Client devices are simple computers designed to run applications from a central server. A Thin Client is a desktop appliance with no hard drive, floppy drive, CD-ROM or other moving components. It is typically a Windows-based terminal, although it can be a Personal Computer (PC) running the Thin Client emulator or even a handheld device, such as a Personal Digital Assistant (PDA). All the application processing takes place on one or more centralized servers. Users can access these applications, locally or remotely via virtually any connection using a standard desktop device, a wireless device, Web browser or Thin Client device. Because the server handles application processing and memory demands, almost any computer can function as a Thin Client. However, there are devices that are specifically designed and optimized for Thin Client protocol and offer the greatest advantages.

Thin Client computing is now an accepted strategy for business computing. It is the next generation and the most technologically advanced computing created to solve the problems experienced with the computing desktops of the corporate environment. The Thin Client concept has brought about a higher level of centralized control to the desktop. A major force behind the success of Thin Client computing is the lower Total Cost of Ownership (TCO) as compared to other models. It is a proven fact that Thin Client computing offers significant savings.

• There are many advantages to Thin Client computing including lower cost, ease-of-use, reliability and security, in addition to some of the following advantages as listed below:
• A standard Thin Client network builds on existing infrastructure; networks, servers, computing devices and software.
• There is reduced time spent in troubleshooting problems and less time trying to fix and maintain computers.
• Thin Clients are a fraction of the cost of PCs.
• Thin Clients are more energy efficient than PCs with some models using 85% less energy than their PC rivals in the real world environment. Less energy translates into cost savings.
• Thin Clients use the network to access data and applications from servers rather than storing information or processing power at the desktop. PCs require substantial memory and computing power.
• An optimized Thin Client, with fewer moving parts and less software complexity, will function without failure significantly longer than a typical PC and require less maintenance. According to studies, Thin Clients run without failure up to 5 times longer than PCs and have 9 times the hardware reliability of the PC. Thin Clients do not have to be replaced every 18-36 months unlike PCs which have a short product life.
• Users do not need to administer Thin Clients and they can be setup in minutes by anyone.
• Thin Clients start in seconds rather than minutes like PCs and are quiet, easy-to-deploy and simple to use.
• Information can be backed up on the server instead of on all the individual PCs. This increases the probability of data getting backed up.
• The size is small, which improves desk space as much of the hardware components of a standard PC are not necessary.
• It is not necessary to keep a large inventory of drives and PCs waiting for a failure to occur. If a Thin Client desktop breaks, a complete replacement can be provided to bring the user back up immediately.
• Obsolescence is greatly reduced. The latest CPU available on the market is not necessary for Thin Client computing, while PCs, to run the latest software often require the latest technology.
• With Thin Clients, it is not necessary to go onsite to adjust the user's desktop as all the administration is brought into the network domain. Updates are made from a central location.
• Even with a diversity of application programs, the desktop is easily supported. A Thin Client can be configured in 5 minutes while a PC or workstation can be configured in 30 minutes, which is 6 times longer.
• Thin Clients are virtually virus proof as they do not have vulnerable openings like floppy drives or CD ROMs where viruses can be introduced. Users cannot load or use unauthorized software on Thin Clients.
• Thin Clients have a lower risk of equipment theft when compared to a PC. By itself, the PC has no great value as the processing power, memory and data are secure on the server.
• Software upgrades, operating system and application software are done once on the server which reduces the downtime for users.
• Network resources are preserved. Demands for increased bandwidth are significantly lowered.
• Thin Client technology delivers central management of IT resources, plus faster and more frequent deployment of new applications and software.
• It permits remote, hands-off configuring, monitoring and administration of desktop devices.
• Utilizing Thin Client technology allows IT personnel to devote more time to more challenging strategic work.
• Thin Clients help people get their work done more efficiently which is beneficial for the individual and the organization.
• With Thin Clients, remote offices can normally be set up in hours and do not need expensive network equipment, configuration and support that are required in a distributed PC environment.
• Thin Client devices are designed to cost less than PCs to run and maintain.

According to Gartner, Thin Clients can save an IT department 80% in support-staff costs.

It is clear that cost is a key consideration for any organization considering a change in computing environments. Most organizations should see large returns in the first year of Thin Client deployment. Support and desktop related costs drop off quickly. Other major savings will result from reduced application downtime and diminished need for user support and training.

In this time of tighter spending and more focused technology investments, Thin Client technology keeps costs low and manageability high. The end result is organizations using Thin Clients are able to manage their bottom lines more effectively.

Less expensive, more efficient, more productive and safer IT architecture are some of the benefits of Thin Clients. Thin Clients and Terminal Services combine the best features of PCs and mainframes; the user-friendly interface and software of PCs plus the reliability and security of mainframes. Thin Client computing is poised to become a major enterprise and business architecture in the coming years as it is a very enticing solution.

Virtualization

After years of vendor hype about virtualization, customers are realizing real-life business and IT benefits from implementing this technology. By moving away from the traditional 'silo' approach of linking applications to a specific IT infrastructure towards an approach that creates shared pools of virtualized server, storage and network resources, and customers can dynamically assign the pooled resources wherever and whenever needed. Although many vendors have focused their selling and marketing efforts on the virtualization benefits for enterprise-class customers, more and more SMB customers are reaping virtualization rewards as well.

Virtualization's benefits of increased utilization, improved service reliability and the positive impact on both internal and external business processes apply to SMB as well as to enterprise-class operations. The products of companies offering virtualization deployment services, particularly in server virtualization, logically 'break' each physical server into several independent virtual servers, allowing customers to run multiple operating systems and applications on a single machine simultaneously. Each virtual server is independent of the others, so failure in one will not affect others. Furthermore, the workload from the failed virtual server can be reassigned to another virtual machine. In a 2007 IDC survey of 19 North American-based IT organizations, 80% of the companies reported adding virtual machines to their systems management portfolios.

Some of the benefits of virtualization are:

Lower number of physical servers - one can reduce hardware maintenance costs because of a lower number of physical servers.

By implementing a server consolidation strategy, one can increase the space utilization efficiency in their data center.

By having each application within its own "virtual server", one can prevent one application from impacting another application when upgrades or changes are made.

One can develop a standard virtual server build that can be easily duplicated which

will speed up server deployment.

• One can deploy multiple operating system technologies on a single hardware platform (i.e. Windows Server 2003, Linux, Windows 2000, etc).

When running in a virtual machine, an operating system can't tell whether it is running on a virtual machine or a physical server, nor can applications or other computers on a network. Nevertheless, a virtual machine is composed entirely of software and contains no hardware components whatsoever.

Compatibility

• Virtual machines are compatible with Sun x64 servers powered by AMD Opteron and Intel Xeon processors.

Isolation

• Virtual machines are isolated from each other as if physically separated.

Encapsulation

• Virtual machines encapsulate a complete computing environment.

Hardware independence

• Virtual machines run independently of underlying hardware.

When IT organizations virtualize the hardware, they empower themselves to make more flexible, dynamic choices in their application deployment and their allocation of resources - business benefits that affect the bottom line- including higher server utilization, improved service levels, ability to better meet changing business requirements, increased business continuity and disaster recovery

Zero downtime maintenance

Through the use of virtualization technology, the days of bringing applications down because of scheduled server maintenance are over. Instead, IT organizations use virtualization to migrate running applications from a server they wish to take down to a backup server. With all applications moved off a server without disruption, it can be maintained or even replaced without any impact on service delivery.

Freedom from vendor-imposed upgrade cycles

Some solutions virtualize the hardware itself, including the processor, memory, disk and I/O resources. Because the hardware that the operating system sees is virtual and not physical, the OS and the software installed on it can be moved from server to server without concern for the underlying platform - freeing IT organizations from vendor-imposed hardware and software upgrade cycles.

Virtual hardware to support legacy operating systems

IT organizations can migrate entire environments from physical servers whose service plans have expired to virtual machines running on state-of-the-art Sun x64 servers. This helps address performance and space, power and cooling concerns by supporting multiple such environments per server.

Dynamic resource sharing

Because some solutions virtualize disk drives as flat files, these files can be moved from server to server to optimize utilization levels and to manage service levels. Resource allocation can be used to manage complimentary applications on the same server. For example, it could be configured to favor a busy On-Line Transaction Processing (OLTP) database during the day, while favoring long-running data warehousing operations at night. For even more dynamic resource management, virtualization technology can dynamically migrate running environments between servers, giving IT organizations the ability to respond to workload fluctuations in real time.

Security and Fault Isolation

Virtualizing at the hardware level encapsulates each guest operating system in its own virtual machine, containing faults to a single environment. This helps increase reliability by limiting the propagation of faults and allowing them to be handled by software, rather than hardware mechanisms. Likewise, because each virtual machine isolates its guest operating system and applications, any security flaw affecting one environment does not affect another.

Business Continuity and backups

With operating systems and applications encapsulated into disk files, they can be backed up as a complete unit and they can be migrated to a secondary datacenter, ready to activate in the event of a failure at the primary location.
