Some people use the cloud. Others build one. This talk will be about building your own enteprise cloud. When running a cloud 3 things are important: scaling, easy (cost effective) maintenance, and stability. These 3 points are very closely related through one subject: automation. Thanks to the easy automation tools like pxe boot (for booting a new setup) and puppet (for configuring a new system) setting up a new server was never this easy. But how can we use these tools to create a scalable infrastructure that is cost effective, stable and easy to maintain? In this talk you will learn about how to design a scalable secure architecture and how to make the right tools work for you without going into to much detail.

Blades
•
•
•
•
•
They are as fast as normal hardware
They don’t take much space
Buy 2 blade centers (in 2 dc’s)
Very fast network i/o
Perfect as virtualization platform

storage
• Or buy big storage boxes
• Very fast
• easy
• Expensive
• Big
• Don’t scale to well
• Or buy normal servers with a lot of storage
• And storage software
• Fast
• More difficult
• Cheaper
• Sizes exactly to your needs.
• Scales very good

You thought you were ready
• Decide on standards!
• You still need a cloud management system
• A configuration management system
• make sure everything is the same on each system
• But keep in flexible

Also
• Setup tool replication everywhere
• The tool designers know better
• Setup HA system for every part in the stack
• Also the configuration / management parts
• Integrate ldap everywhere
• Keep your authentication plain and simple
