The document discusses challenges facing today's enterprises such as cutting costs, driving value with tight budgets, maintaining security while increasing access, and finding the right transformative capabilities. It then discusses challenges in building applications related to scaling, availability, and costs. The remainder summarizes Microsoft's Windows Azure cloud computing platform, how it addresses these challenges, example use cases, and pricing models.

5. Capacity? Servers? Bandwidth? Storage?

6. How do you scale up or down over time?

7. How can you handle peak loads?

8. How do you provide high availability?

9. What are the upfront capital costs?

20. Defining Windows Azure ArchitectureThe Fabric Controller communicates with every server within the Fabric. It manages the Windows Azure operating system, monitors every application, decides where new applications should run – optimizing hardware utilization.

21. Service Management is performed by the Fabric Controller, which controls all the resources within the data center. The Fabric Controller deploys your service and monitors the overall health of the fabric.Security and Control State-of-the-art physical security processes combined with strictly controlled OS access model. Data is replicated in multiple fault domains in location selected by the customer. Virtualized Computation provides massive application scalability. Customers can build a combination of web and worker roles. Those roles can be replicated as needed to scale the applications and computational processing power.Storage Services allow customers to scale to store large amounts of data – in any format – for any length of time, only paying for what they use or store.State-of-the-art data centers located around the world. Host your applications and data securely, accessible from everywhere you allow.Windows Azure Automates the Management of Your IT Resources

22.

23. Developing Applications for Windows AzureFamiliar Developer ExperienceDesigned for InteroperabilityProven Microsoft TechnologiesDevelopment: Visual Studio integration, offline cloud simulation

24. Maintenance: Local debugging, APIs for logging

25. Management: APIs for deployment management

26. SOAP and REST protocols

27. XML file formats

28. Commitment to support Java, PHP, Python and other popular programming languages
