Sitecore has recently released a version that supports deploying Sitecore Experience Platform (XP) to Azure web-apps – a Platform as a Service (PaaS) offering. Sitecore can also be installed on virtual machines residing in Azure’s Infrastructure as a Service (IaaS) offerings.

Choosing the right strategy will depend on an organization’s maturity model and the motivation to dive into full-on cloud computing. Below is a quick overview of the two flavors of Sitecore installation on Microsoft Azure. It should help you decide a path for your deployment strategy.
