Platform as a Service

Platform-as-a-Service (PaaS) is a model for delivering complete development platforms as a service over the internet. With the PaaS, Microsoft Azure platform can help you with the development, testing, deployment and on-going maintenance of applications without the cost of buying the underlying infrastructure and software environments.

Key technologies

  • Windows Azure provides a scalable environment with computation, storage, hosting, and management capabilities. It links to on-premises applications with secure connectivity, messaging, and identity management.
  • SQL Azure is a secure relational database service, based on SQL Server technologies and hosted by Microsoft in the cloud, which means you no longer have to install, setup, patch or manage any software.
  • Windows Azure AppFabric is a cloud middleware platform for developing, deploying and managing applications on the Windows Azure Platform. It also makes it simpler to connect on-premises applications with cloud-based services.

Useful resources

  • At PDC 2010, there were several Windows Azure announcements about product features that let your organisation benefit from cloud computing, at the same time letting you retain control over your IT environment.
  • Virtual Machine (VM) role in Windows Azure runs an image which is stored on a virtual hard disk (VHD) of a Windows Server 2008 R2 virtual machine. This VHD is created using an on-premise Windows Server machine then uploaded to Windows Azure.
  • Windows Azure Connect enables a simple and easy-to-manage device to set-up an IP-based network connectivity between on-premise and Windows Azure resources. This is the first Virtual Network feature that we'll be making available as a CTP later this year.
