Lifestyle experts will tell you that moving to a new home is one of the most stressful events people undertake during their lifetime yet, given a choice between that or moving applications to a new platform, many of us would unhesitatingly start packing the china. Thankfully, however, moving your applications to Azure is a breeze.
For many years, Neumeric technologies has been building highly scalable applications in datacenters around the world—applications that have global reach and high availability, and offer great functionality to users. Azure allows you to take advantage of the same infrastructure to deploy your own applications, with the corresponding capabilities to reduce your maintenance requirements, maximize performance and minimize costs. Of course, people have been outsourcing their applications to third-party hosting companies for many years. This might be renting rack space or a server in a remote datacenter to install and run their applications, or it might just mean renting space on a Web server and database from a hosting company. In either case, however, the range of features available is usually limited. Typically, there’s no authentication mechanism, message queuing, traffic management, data synchronization or other peripheral services that are a standard part of Azure.
It might seem like these capabilities make moving applications to Azure complex, but if you take the time to consider your requirements and explore the available features, moving to Azure can be a quick and relatively easy process. To help you understand the options and make the correct decisions, the patterns & practices group at Microsoft has recently published an updated version of the Azure migration guide: “Moving Applications to the Cloud on Azure”. The guide covers a wide range of scenarios for migrating applications to Azure. In the remainder of this article I’ll explore these scenarios, look at the decisions you’ll need to make, and see how the guide provides practical and useful advice to help you make the appropriate choices. While the guide follows a somewhat-contrived multi-step migration process—which most people are unlikely to follow in its entirety—this approach demonstrates most of the options and shows the capabilities of Azure that might be useful in your own applications. taken from the guide, shows a conceptual map of the migration paths you might follow when moving an application from an on-premises data center to Azure.
