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.

Simple Notification Service (SNS)

Simple Notification Service (SNS) is a real-time messaging service designed to allow applications to send alerts and messages to multiple receivers at the same time. Amazon has kindly provided a tab for us to manage our SNS subscriptions in the AWS Console, so we will be using this to manage our SNS service. Also, we will be using an external service called, an excellent website used for visualising Web Hooks used by services such as SNS.

An overview of how SNS works

SNS works by providing a Topic, which can be Subscribed to by multiple subscribers using various technologies, such as e-mail and HTTP. By providing a single topic, one message, when posted, may be reliably delivered to multiple subscribers. An example of this is an alert, which may be posted by an application such as our Waaah sample application.


Later on in this chapter, I will show how we can modify Waaah to make use of both SQS and SNS to enhance its existing functionality...
