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.

Elastic Block Store (EBS)


The Elastic Block Store (EBS) functionality is accessed from the Amazon EC2 tab, and then via the Volumes link in the Navigation pane.

Elastic Block Store (EBS) is the disk storage system for AWS and operates similarly to an external Storage Area Network (SAN) in a typical data center. EBS is a system that enables EC2 instances to access disks, which are configured, created, and managed externally to each EC2 instance.

EBS disks can be created independently of an EC2 instance and can be moved between EC2 instances at will.

In fact, if EC2 is the engine of AWS, you could consider EBS to be the fuel tank, holding all the resources for applications running on EC2.

EBS disks are a powerful feature of AWS and hold persistent data. This means that any data stored on an EBS volume will persist after an EC2 instance has been stopped or terminated.

EBS disk is also faster than the instance disk associated with an EC2 running instance if the instance uses the S3 instance store...
