The adoption of cloud computing affects all aspects of an enterprise, from a CFO's financial planning to an IT admin's daily workload. A survey released by TechTarget sought to examine the use of cloud computing in enterprise IT. And whether it was for financial reasons, high availability or easing the burden of IT maintenance, the survey found that cloud computing adoption is on the rise. Looking at adoption trends, costs and use cases can give a full picture of the cloud computing landscape currently in enterprise IT.
This updated guide gives insight into the pulse of the cloud computing market in 2014.

Cloud computing adoption trends and costs
Enterprises choose to adopt public cloud services or build a private cloud for various reasons that align with their company goals. The TechTarget survey results gave a glimpse into these motivations, uncovering underlying cloud adoption trends and cost analyses.
Cloud computing use cases
Learning from the mistakes and successes of others is one of the best ways to move forward with any new technology. These use cases reveal potential bumps -- and surprising benefits -- in the cloud computing adoption process.
Cloud computing glossary
Do you speak cloud? Let's start at the beginning. Cloud computing is a general term for anything that involves delivering hosted services over the Internet. Did you know that the name cloud was inspired by the symbol that's used to represent the Internet in flowcharts and diagrams?
A cloud service has three distinct characteristics that differentiate it from traditional hosting. It is sold on demand, it is highly scalable and the service is fully managed by the provider.
Cloud services are broadly divided into three categories: Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). A cloud can be private or public. A public cloud sells services to anyone on the Internet. A private cloud sits behind a firewall and "sells" services over the Internet to corporate customers who are also inside the firewall.
