  2. There is an SLA
    • Windows Azure delivers a 99.95% monthly SLA
  3. Azure offers Platform as a Service Capabilities
    • This enables you to build and run highly available applications without focusing on the infrastructure.
    • It provides automatic OS and service patching, built in network load balancing and resiliency to hardware failure.
    • It supports a deployment model that enables you to upgrade your application without downtime.
  4. Azure is http-based and based on open standards
    • Features and services are exposed using open REST protocols.
  5. Choose the language that works best
    • The Windows Azure client libraries are available for multiple programming languages, and are released under an open source license and hosted on GitHub.
  6. Scale automatically and with a minimum of effort
    • It is a fully automated self-service platform that allows you to provision resources within minutes.
    • Elastically grow or shrink your resource usage based on your needs.
    • You only pay for the resources your application uses.
  7. Global footprint
    • Windows Azure is available in multiple datacenters around the world, enabling you to deploy your applications close to your customers.
    • Windows Azure’s distributed caching and CDN services allow you to reduce latency and deliver great application performance anywhere in the world.
  8. Support for many, many data stores
    • You can store data using relational SQL databases, NoSQL table stores, and unstructured blob stores, and optionally use Hadoop and business intelligence services to data-mine it.
  9. Bridge On-Premises Applications and Cloud Applications
    • You can take advantage of Windows Azure’s robust messaging capabilities to enable scalable distributed applications, as well as deliver hybrid solutions that run across a cloud and on-premises enterprise environment.
