Cloud Confusion
Companies are embracing the Cloud more and more each day. The reasons are compelling, yet differ with kinds of services that are available in the Cloud. To make things even more confusing, you can even have a private Cloud. Today I just wanted to talk about some of the Acronyms surrounding the Cloud to shed some light on what is going on.
IaaS – Infrastructure as a Service
IaaS is the outsourcing of hardware to a Cloud vendor such as Amazon EC2. Amazon provides you with machines and network connectivity. You are fully responsible for the Operating System and the software running on it. You perform updates, etc. Primarily, they keep the lights on.
PaaS – Platform as a Service
PaaS is outsourcing the operation of your software in machines where the Operating System is supported by the Service Provider. Azure is an example of PaaS. They allow you to increase/decrease your capacity without requiring your operations professional to manage anything other than your software.
SaaS – Software as a Service
Software as a Service provides software for you over the internet. Most of us are familiar with Google’s office like offerings. Your company does not maintain any licenses for Word Processing, etc. Instead, you rent access to the software. In this case you don’t have to maintain licenses, install software, or maintain bug/security patches.
A private Cloud is often designed using the PaaS model of software distribution, while you maintain the responsibility of maintaining the hardware.
Obviously there is a lot more to the Cloud than can be described in a few paragraphs. Feel free to send your comments regarding the Cloud and how you have used it? Drop an Email to btaylor@sswug.org.
