IT infrastructure is generally defined in two ways: either by those who use it to define it as a group of computer hardware, software, networking devices and other related elements, or by those who use it to define it as the collection of information technology elements that are a critical part of an IT service. Most people will agree on the first definition. In most cases, it is simply the collection of computers, networking devices, storage devices, and other IT equipment. It can also include the processes used to maintain the equipment and people running the systems.
When defining it infrastructure, one tends to look at it from a broad perspective, looking at all the different pieces involved and what they do. However, it is also necessary to define it infrastructure within a smaller context, which may be more relevant for the business and its needs. Broaden your perspective and define it infrastructure from a narrower perspective: What types of things does this group of equipment or software do? What are their functions and how do they interact with each other? What types of users do they serve?
Within this broader perspective you will find that you have a collection of components, including servers, workstations, client computers and other hardware. Each of these items represents a discrete system and infrastructure. If we take this wider view, we find that there are four main trends in IT infrastructure evolution. These include application software, database development, web based services and virtualization. Virtualization refers to the use of software applications that run both in the data center and on the host operating system, relieving users of needing to know anything about networking or servers.
Application software, also called application software, is the most common way to define it infrastructure. There are a number of groups under this category, including systems integrators, developers, system designers, and systems integrators. In today’s ever-changing marketplace, the role of these specialists involves ensuring that different platforms can be used to deliver specific information system applications. The developers create these applications, while the systems integrators provide support for them. These groups are key to the smooth running of any robust information system.
Another trend in IT infrastructure has been developing new and more efficient servers. The number of parallel machines that can be used to run computing devices has increased dramatically. The IT world now has an entire hierarchy of servers – network, storage, power, and processing – that must be efficient and robust enough to meet the needs of all kinds of organizations. In order to improve server efficiency, firms must define and deploy new and more efficient servers.
Storage is another important aspect of information system architecture. This aspect involves the physical storage and access of electronic data. It may involve the use of a network of local storage devices, or it might be a combination of on-site and remote storage. The role of this component is growing in importance, as firms realize that they need to have more flexibility when it comes to the availability of data. This also helps them to manage their information better.
Another aspect that must be taken into consideration when you want to define it infrastructure from both a technology and a services perspective is virtualization. There are many ways to implement virtualization. Each specific type has its advantages and disadvantages. A firm must take some time to evaluate the strengths and weaknesses of each virtualization method.
A final consideration is the use of cloud computing. Cloud computing refers to the use of external networks to store, process, and deliver data. The advantage of using external sources to store and deliver this data is that the users do not need to have any kind of on-site IT infrastructure. A firm can therefore save significant expense that would otherwise be required for on-site IT infrastructure. The use of cloud computing requires a firm to define virtualization and to define how the service provider will manage the use of the cloud. A good cloud computing provider will be flexible and will meet all your needs.
