In the ever-evolving technology world, the time for a traditional on-premises data centre is reducing at a rapid pace with the evolution of the latest cloud technologies and platform in a bid to cut costs and improve agility.
Infrastructure as a service (Iaas) is a service model in which third-party provider hosts and maintains core infrastructure that includes hardware, software, storage, servers, data center space, networking and networking services (e.g. firewalls) on behalf of the customer. This means that the customers are only charged for the infrastructure they use along with the facility of hosting the applications in a highly secure and scalable environment.
The leading cloud providers in the market are Amazon Web Services(AWS), Microsoft Azure and Google Cloud Platform. According to Gartner, Inc. prediction the worldwide public cloud services market is projected to grow 17.5 percent in 2019 to total $214.3 billion, up from $182.4 billion in 2018. Iaas is the fastest growing market segment within cloud system that is forecast to grow 27.5% in 2019 to reach worth $38.9 billion.
The Cloud Platform infrastructure service is clearly dominated by AWS since day one, as AWS was the first one to step into the market with cloud technology in 2006. According to Q1 2019, Synergy Research Group’s figures AWS emerged as the clear market global leader in public Iaas and PaaS revenues with 38 percent market share while followed by Microsoft at 18 percent and Google at 9 percent market share respectively.
Although AWS is dominant in the market, Microsoft is quickly catching up in bridging the gap under the leadership of CEO Satya Nadella, building a huge global cloud of its own and ease of Hybrid facility.
Features and Services
In cloud technology one-size-fits-all solution is not applicable, as to choose the right cloud platform depends entirely on the individual customer needs, type of business, cost and workloads.
However, all the three biggest cloud providers offer largely similar basic capabilities around storage, compute power, database, analytics and networking with flexibility, scalability and reliability.
AWS offers largest range of services, around 140 as of Q2 2019, across storage, compute, database, analytics, networking, mobile, management tools, developer tools, IoT, security and enterprise applications. There are 4700+ products to choose from various vendors in AWS marketplace.
