Among the three basic cloud hosting service models, Infrastructure as a Service has contributed significantly to overall growth of cloud adoption in 2016. In fact IaaS has registered the highest rate of growth and is poised to continue the growth spell in the year 2017 also.
IaaS as offers support to SaaS
Infrastructure as a Service provides access to virtualized hardware resources to support development of IT platforms for clients. Gartner’s prediction regarding the growth of IaaS market has come true since the IaaS market has reached $22 billion in 2016 as projected in the very beginning of 2016. It is worth noting that the growth of IaaS market is a whopping 38 percent over 2015, although it accounts only for one tenth of the total cloud market.
Software as a Service has been around for a long time even when it was not referred to as SaaS. Organizations have been availing wide range of software solutions via internet. Since these are accessible through web browser and need no special installation on local device, these are hugely popular among organizations.
In spite of the fact that SaaS has been around for quite some time, its growth has become visible only after introduction of Infrastructure as a Service. Both service models are inter-dependent for their individual growth. Growth of Software as a Service will continue with proliferation of Infrastructure as a Service.
Major providers including Microsoft are rapidly moving their solutions to cloud associated model such as Dynamics 365. Office 365, and Windows as a Service to name a few. Overall cloud growth is propelled not only by growth of IaaS but is also being boosted by three important cloud players including Microsoft, Google, and IBM. There has been an impressive growth in cloud based revenues of these organizations in terms of sequential growth and not just yearly growth.
Sequential growth refers to consistent growth in revenue earnings. It should be also noted that these companies are expanding their infrastructural capacities and are also simultaneously supporting growth of cloud applications.
This underlines significance of IaaS, which will act as a robust groundwork for growing Software as a Service.
This helps us understand various phases of cloud growth. The first phase was influenced by movement of software solutions to cloud. The second phase is going to be governed by applications based on Artificial Intelligence, cloud gaming, Internet of Things and virtual reality among other high end technologies. It is from this perspective that IaaS growth is essential to overall cloud growth.
The growth of cloud adoption is set to speed up in 2017 since more and more vendors are offering private, public, and hosted services in the domain of cloud computing. Since all aspects of infrastructure in IaaS including servers, networking, and storage, are managed and provided by service enabler. Customers can focus their attention on business rather than maintenance of hardware and software.
Infrastructure as a Service provides virtualized infrastructure for hardware as well as software and helps enterprises acquire abilities to move on to adopt Platform as a Service. Enterprises can create compute images for on demand provisioning of storage, computing resource, and network. This has led to a remarkable rise in demand for IaaS with a compound annual growth rate of 42 percent.
Important features of IaaS
Let us appreciate certain vital attributes of IaaS that have been responsible for growth of cloud adoption in general.
Resource distribution- IaaS adopts a service approach for distribution of storage space, CPU, and hard disk. Users can also avail hardware as well as software, which can be provisioned instantly.
Effective collaboration- It is possible for diverse teams of to work on a single component of hardware without restrictions of place and time because all resources are accessible via internet. IaaS facilitates al employees to operate from remote locations, accessing work resources even while on the go. IaaS is designed to be seamlessly compatible with demands of modern work culture that allows to work from anywhere. Hence IaaS makes organizations geographically immune.
Dynamic scalability- This can be considered as the most practical advantage of IaaS especially for enterprises that need to handle frequent traffic spikes, changing requirements, and business opportunities. Providers of IaaS solutions are well equipped with high end servers, state of the art networking equipment, and large storage capacity to easily cater to the needs of clients with remarkable agility.
Assured reliability- By spreading out resources across number of servers and locations, IaaS providers ensure that there is no single point of failure. IaaS guarantees seamless availability even if any component or server fails to operate.
Utility based payment model- Since customers of IaaS are only required to pay for resources that are consumed, one can plan optimum use of resources. This provides outstanding cost effectiveness as well.
IaaS is the most sought after service model of cloud computing. IaaS enables deployment of resources, including processing power, networking, servers, and storage to name a few.
