What is Infrastructure as a Service?

IT and ITES companies very well understand the benefits of taking their business operations on cloud. It has offered businesses increased agility and more predictable budgeting. In fact increasingly ‘cloud first’ is becoming the mantra for many organizations when it comes to new software solutions.

But when it comes to IaaS (Infrastructure as a Service), there are enterprises that are less clear on the specific use cases. IaaS can help your organization deliver IT capabilities and achieve desired business outcomes.

However, as the cloud computing matures, more IT decision makers are realizing the potential advantages of IaaS solutions such as Microsoft Azure to launch their projects on the cloud. It is strategically important for organizations to more resources to the cloud.

IaaS offers benefits such as flexibility, scalability, and reliability. These three terms are such that can be heard in any discussion around cloud computing, but little from the context of Infrastructure as Service offerings. IaaS can be thought of as ‘rented hardware’ that organizations can access instantly with relatively little upfront cost. IaaS provides storage, computing and networking functions for either existing or new projects.

Benefits of IaaS

Allows IT and ITES companies to focus on their core activities – IaaS provides ready to use infrastructure as a service. That means organizations don’t have to worry about building their own infrastructure. The time and resource saved can be directed towards strengthening their core business activities. Moreover maintaining IT infrastructure may not be the core competence for many organizations.

Unmatched flexibility – IaaS provides every infrastructure component as a separate service, for example server as a service, hardware as a service, storage as a service, computing as a service and so on and so forth. This makes the entire process hassle free and adds lot of flexibility in terms of paying for only the infrastructure component needed and only for as long as they were used.

 Pay per use and pay as you go subscription model – IaaS follows utility service model or subscription based model. Ready to use IaaS offerings cuts down implementation time and makes customization a breeze. This aspect of IaaS is particularly beneficial for firms to take their products and services to market quickly and easily.

Scale up or down – IaaS makes it easy to scale up or down the infrastructure service based on the application use. IaaS is best for most kind of applications, but particularly beneficial for applications that experience significant spikes and troughs on the usage of infrastructures. IaaS services can be quickly scaled up in case of an upturn in demand and scaled down when there is low demand.

Investment cap – IaaS is more beneficial for companies with limited capital to invest in hardware or infrastructure. Many small and medium scale companies cannot afford the upfront cost of their IT infrastructure. With no upfront investment and maintenance commitment, IaaS makes a great choice.

IaaS is great and important decision that any IT or ITES Company would take. But it’s a decision that should be taken with after proper self and vendor evaluation.
