Amazon Web Services: Migrating your .NET Enterprise Application

By: Rob Linton

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.

Mapping of AWS offerings to our sample application

We have finally looked at the majority of what AWS offers, and now we can begin the process of mapping each of the functions of our sample application to the functions provided by AWS.

Let's start by breaking our sample application into infrastructure areas, which we can map to AWS infrastructure services. The following are the infrastructure services required by our sample application.

  • Load balancing

  • Hardware (Servers)

  • Hard disk storage

  • Firewall security

  • Performance monitoring

  • Database servers

Let's look at each of these in turn.

Load balancing

The load balancing provided by AWS ELB matches directly against the load balancing required by our sample application. However, when matching against our sample application, HTTP session cookies will need to be turned on in our ELB instance to ensure that Session Stickiness is in place. This ensures that sessions in progress transverse the same web server and retain their state.

Hardware (Servers)

The current...
