Although Software-as-a-Service has long been the most popular component of cloud computing, Infrastructure-as-a-Service is now one of the most highly demanded models. Companies have worked to modernize their IT capabilities and frameworks, and enterprise IaaS cloud services appear to be the most affordable and feasible option for many firms.

IDC forecast illustrates IaaS spread
Biztech2 India recently reported that the latest forecasts from IDC revealed several trends in the enterprise cloud adoption arena, with more companies choosing to deploy robust models rather than one model at a time. For example, firms have traditionally started cloud adoption procedures with SaaS, using the tools for basic functions such as email and file sharing.

Now, as more companies work to customize their IT frameworks and integrate the various services and solutions, SaaS, IaaS and Platform-as-a-Service are converging. According to the news provider, IDC analysts predict that companies will increasingly demand properly configured IaaS and PaaS combinations that yield enhanced interoperability.

Specifically in emerging markets such as parts of Asia, the source cited IDC's forecast that IaaS will experience monumental growth globally through the next three years, with competition heating up among the various firms vying for higher revenues.

Biztech2 India noted that IaaS will likely experience such massive growth at least partly because of increased demand for customized applications and resilient IT infrastructure. Private IaaS can help to substantially improve a company's flexibility, as the on-demand services reduce the need for expensive equipment purchases.

Frost and Sullivan more optimistic
Frost and Sullivan recently released its latest forecast for IaaS adoption in Australia, and asserted that the market for such solutions will expand to $380 million in annual revenues by 2017. Much like virtually every other region of the world, demand for these types of services is already starting to spike, and experts believe the industry has what it takes to sustain this growth in the long term.

According to the researchers at the firm, reduced capital expenditures, increased scalability of resources and demand for mobile-accessible systems will drive revenue enhancements in Australia. These same benefits can be easily applied to the reasons for enterprise IaaS demand growth in other regions as well, as companies work to tighten their grasps on IT budgets amid market turbulence.

The firm noted that, should this forecast manifest into reality, it would represent a compound annual growth rate of roughly 43 percent through 2017.
