David Pallmann, General Manager at Neudesic has published one of the best explanations of Cloud Computing in Windows Azure Design Patterns. The title is a double misnomer – it isn’t just about Azure, and it is far more than Design Patterns.
Pallmann’s Periodic Table of Cloud Patterns is one of the best tools for visually capturing the various components and facets of Cloud Computing. He uses these elements very effectively to touch on Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS) before delving into Windows Azure’s PaaS offerings.
Although the slides cover Windows Azure, Pallmann’s points are easily abstracted to Cloud Computing in general. And he provides a very solid foundation for digging into areas such as:
- Claims-based Security
- Service Bus (resilient queue)
- Storage – Blobs, Tables, Queues
- Database – SQL Azure
- Compute Instance Types
Overall an excellent presentation for Cloud Computing and well worth reviewing!
