VMware Cloud Foundry: A Cloud Primer

1         Introduction

It’s cloudy, today. But I’m not speaking about the weather in northern hemisphere autumn. Cloud Computing, two words that cannot be explained with just a sentence, is now a reality, born to change our (digital) lives.

Cloud Computing may mean different things to different people. For some, it would be having their personal documents, photos and music synchronized “in the cloud” and accessible through their PC or mobile device. For others, it would be being able to run their favorite games and to do their favorite stuff anywhere, anytime. It may be a cost-effective, agile hosting solution, an elastic production environment for databases and application servers, and many, many other things. Google Docs, Picasa, iCloud, Facebook, Twitter, Foursquare, Amazon EC2…

In this article, though, we will be discussing about Cloud Computing as a platform where developers can deploy their highly scalable, highly available solutions. We call this Platform-as-a-Service, or PaaS for short. PaaS also means a lot of things but for us is forgetting about dealing with the OS, the application server, the disc or the memory in the server. You just have your “application space”, where you can upload your solutions, execute them, monitor how they behave and control the amount of resources available to them.

You don’t know where your application physically is, the type of host server, operating system configuration or even how the application server is configured at all. You may certainly know about some or all of this, but it is really not needed to achieve your targets: develop your idea and make it available to your clients (no matter how much or where they are) in a hassle.

VMware Cloud Foundry is one of such platforms.
