Amazon Web Services: Migrating your .NET Enterprise Application

Overview of this book

Amazon Web Services is an Infrastructure as a Service (IaaS) platform in the Cloud, which businesses can take advantage of as their needs demand. The Amazon Cloud provides the enterprise with the flexibility to choose whichever solution is required to solve specific problems, ultimately reducing costs by only paying for what you use. While enterprises understand moving their applications among infrastructure they own and manage, the differences in Amazon's infrastructure bring up specific business, legal, technical, and regulatory issues to get to grips with. This step-by-step guide to moving your Enterprise .NET application to Amazon covers not only the concept, technical design, and strategy, but also enlightens readers about the business strategy and in-depth implementation details involved in moving an application to Amazon. You'll discover how to map your requirements against the Amazon Cloud, as well as secure and enhance your application with AWS. This book helps readers achieve their goal of migrating a .NET Enterprise Application to the AWS cloud. It guides you through the process one step at a time with a sample enterprise application migration. After comparing the existing application with the newly migrated version, it then moves on to explain how to make the hosted application better. It covers how to leverage some of the scalability and redundancy built into the Cloud, and along the way you'll learn about all of the major AWS products like EC2, S3, and EBS.

Patch Management, Quality Assurance (QA), and backups


Now that we have covered off load testing, it's time to look at Patch Management, Quality Assurance (QA), and backups, all of which are related.

One of the major issues with the management of production applications is the management of day-to-day issues, such as releases of new versions, creation of test environments and testing, and application of patches. These are usually limited by the availability of hardware and the availability of up-to-date environments for testing. However, with AWS we have a tremendous advantage; we no longer need to wait for hardware to be provisioned or environments to be created!

Using our backups from our database server in conjunction with the ability to bundle live production instances, we have all the tools we need to create exact duplicates of the production environment at any time.

Let's look at how we would use this in a production environment.

The problem to be solved

For our example, let's pretend for...
