Cloud Computing

Cloud computing is the delivery of computing services such as servers, storage, databases, networking, software, analytics, and more by way of the Internet (“the cloud”). Companies offering cloud computing services are called cloud providers and typically charge for cloud computing services based on usage, similar to how you’re billed for water or electricity at home.

Cloud Computing Services

There are three major groups of Cloud Services: IaaS, PaaS, and SaaS.  Most cloud computing services fall into three broad groups.

IaaS Infrastructure-as-a-Service is the renting of IT infrastructure —servers and virtual machines (VMs), storage, networks, operating systems—from a cloud provider on a pay-as-you-go basis.

PaaS – Platform-as-a-Service  refers to cloud computing services that supply an on-demand environment for developing, testing, delivering, and managing software applications. Developers can quickly create web or mobile apps, without worrying about setting up or managing the underlying infrastructure of servers, storage, network, and databases needed for development.

SaaSSoftware-as-a-Service delivers software applications over the Internet, on demand and typically on a subscription basis. The Cloud providers host and manage the software application and underlying infrastructure, and handle any maintenance, like software upgrades and security patching.

Cloud Computing 6% IT Budget

Gartner estimated that about $205 billion, or 6% of the world’s IT budget of $3.4 trillion, would be spent on cloud computing in 2016 and expected to grow to $240 billion 2017. Cloud computing not only is a large portion of the IT market, it is also the foundation for the big data battle.

The latest battleground is  the mining of the data stored in the cloud  and use the insights to offer new services or improve existing ones.
