[TITLE LE]

Windows Azure overview and Fundamentals Goksin Bakir Microsoft

• A set of connected servers
• On which developers can:

– Install and run services – Store and retrieve data

What Is The Cloud?

• It is an operating system for the cloud
• It is designed for utility computing
• It has four primary features:

– Service management – Compute – Storage – Developer experience

What Is Windows Azure?

• Select your hardware, wire it all together
• Find some device drivers
• Write a file system
• Write a job scheduler
• Write an application installer
• …
• This would be a complete waste of time!

Imagine Building A Desktop Application In This Way:

But This Is What Every Cloud Developer Has To Do Today!

Business logic

Datacenter Respond to hardware failures Add storage capacity Handle increase in traffic Diagnose service failures Apply OS patches Perform live upgrade for new feature Expand to new locale

Service “glue” and operations

…

• The same as a desktop OS, but on connected

servers:

– Abstract underlying environment – Shared file system (across servers) – Resource allocation – Programming environments

• And more: Utility computing

– 24/7 operation – Pay for what you use – Simpler, transparent administration
