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.

In the previous sections, we briefly looked at how we can use Amazon CloudWatch to monitor and trigger alarms for use in autoscaling. In this section, we will look at how CloudWatch is accessed from the AWS console, and how our actions from the previous sections appear in the AWS console.

CloudWatch in the AWS console

CloudWatch is also now available in the AWS console in its detailed form.

  1. To access CloudWatch, click on the CloudWatch tab in the AWS console:

    The first thing you may notice is that there are already two alarms specified, those we specified for our autoscaling web group (WebLowCLUAlarm and WebHighCPUAlarm). One thing I didn't cover in the previous section was that once an autoscaling group has been created along with the relevant policies, these can be managed from within the AWS console.

  2. To demonstrate this, let's create a new alarm that sends an SNS alert when the AppAutoScaleGroup falls below 10 percent for more than 120 seconds...
