In response to the massive data generation by enterprises due to IoT and the growing trend of data enterprises transferring their enormous data to offsite premises, IaaS implementation is set to grow by leaps and bounds. In fact, according to Gartner, IaaS is poised to be the highest growing cloud model with projected growth of more than 38 percent in 2016.

         

Current scenario of IaaS implementation

Backed by government sponsored Digital India program and adoption of SMAC concept by growing number of enterprises, Indian IT industry is going through a significant phase of growth.

It is an established fact that the man hours and in house technical expertise required for maintaining and monitoring in house IT infrastructure can be channelized to accomplish more productive workloads by offloading the IT related tasks to cloud service providers.

Since operating and maintaining resource intensive in-house data center facilities is becoming increasingly challenging, enterprises are exploring ways to reduce capital expenditure by adopting outsourcing of IT infrastructure in general and cloud based services such as IaaS, PaaS, and SaaS in particular.

IT managers are analyzing different workloads to determine which of these needs to be continued to be operated on site and which should be moved to cloud.

Practical advantages of IaaS

Infrastructure as a Service (IaaS) is capable of providing future perfect solutions to organizations that can not only manage increasing volumes of workloads but are also able to respond easily to needs for development of innovative and competitive solutions.

As far as testing and development initiatives are concerned, IaaS helps organizations mitigate infrastructure costs by providing practically unlimited scalability and flexibility to expedite time for marketing the final products. This is backed by a cloud environment that guarantees SLA backed 99.999 percent uptime in addition to excellent security and remarkable compliance.

We can consider following distinct factors that encourage CIOs to adopt IaaS.

Cost efficiency- The most striking advantages for budget conscious organizations is the low cost of physical infrastructure that also includes reduced need for maintenance and repairs of equipment and need for staff to manage the same. Cloud based resources empower organizations to avail capacities as and when required, thus reducing need to purchase additional infrastructure to cater to growing demands.

Cost efficiency of cloud is more evident in the mode of payment for availing cloud solutions. The utility based model of payment facilitates companies to pay only for resources that are being consumed. Organizations are not required to continue with the services if these are not being used.

Flexibility- Every enterprise needs to adopt solutions that are flexible and scalable. This improves agility of business processes. Cloud based IaaS model is appreciated for its flexibility as well as on demand scalability. Enterprises are in a much better position to respond quickly to fluctuating demands.

Stable and secure- IaaS is a boon for organizations that operate from diverse geographical locations. It is observed that management of business continuity and Disaster Recovery is extremely challenging through legacy methods, if there are disparate locations spanning large geographical area.

Enterprises can design an integrated DR plan that not only enhances ease of managing business continuity at diverse locations but can also prove to be highly economical.

             

Reasons for growth in IaaS adoption

The reason why IaaS is emerging as the most sought after cloud model is the advantages of cost efficiency. According reliable sources 29 percent enterprises have already embraced one or more cloud systems while a whopping 31 per cent enterprises plan to implement cloud within a period of 12 months. This implies that almost 60 per cent organizations would have adopted cloud solutions to reduce IT workloads and gain better agility and efficiency.

There is a rapid shift to use of mobile computing by professionals and organizations for performing routine tasks including data exchange, meetings, email sharing, and, more. This is further boosted by availability of wide spectrum of smart phones, tablets, and other convenient devices. Further it is predicted that at the end of year 2020, number of devices connected by IoT will swell to reach 20 billion.

There is a need of better solutions to handle massive amount of data that is the result of mobile computing as well as Internet of Things. Naturally, businesses and large organizations are exploring smart cloud for solutions such as IaaS to manage Big Data.

Emergence of startups is also adding to growth in demand for IaaS. This is for the simple reason that these nascent enterprises are not investing funds for building physical IT infrastructures or purchasing cost intensive equipment. The budding entrepreneurs would rather prefer to rely on technologies such as IaaS that are future ready and economically more viable than traditional solutions.

Following are the projected use cases of cloud backed solutions in near future according to WindowsITPro.com:

   - Handling testing, development, and pre-production workloads

   - Disaster recovery

   - New production workloads

Cloud is the most viable option for managing development of new software applications because the cloud infrastructure is easy to procure on demand and can be de-commissioned as soon as the task is finished.

Conclusion

Enormous growth in data generation and need for more agile and cost effective solutions by enterprises are some of the factors behind exponential growth in demand for IaaS solutions.
