Dear Amazon Web Services Customer, We are excited to announce the public beta of several new features for the Amazon Elastic Compute Cloud (Amazon EC2): Amazon CloudWatch, a web service for monitoring AWS cloud resources, Auto Scaling for automatically growing and shrinking Amazon EC2 capacity based on demand, and Elastic Load Balancing for distributing incoming traffic across Amazon EC2 compute instances. Together, these capabilities provide you with visibility into the health and usage of your AWS compute resources, enhance application performance, and lower costs. Monitoring Amazon CloudWatch is a web service that provides monitoring for AWS cloud resources, starting with Amazon EC2. It provides customers with visibility into resource utilization, operational performance, and overall demand patterns -- including metrics such as CPU utilization, disk reads and writes, and network traffic. To use Amazon CloudWatch, simply select the Amazon EC2 instances that you'd like to monitor; within minutes, Amazon CloudWatch will begin aggregating and storing monitoring data that can be accessed using web service APIs or Command Line Tools. Auto Scaling Auto Scaling allows you to automatically scale your Amazon EC2 capacity up or down according to conditions you define. With Auto Scaling, you can ensure that the number of Amazon EC2 instances you're using scales up seamlessly during demand spikes to maintain performance, and scales down automatically during demand lulls to minimize costs. Auto Scaling is particularly well suited for applications that experience hourly, daily, or weekly variability in usage. Auto Scaling is enabled by Amazon CloudWatch and available at no additional charge beyond Amazon CloudWatch fees. Elastic Load Balancing Elastic Load Balancing automatically distributes incoming application traffic across multiple Amazon EC2 instances. It enables you to achieve even greater fault tolerance in your applications, seamlessly providing the amount of load balancing capacity needed in response to incoming application traffic. Elastic Load Balancing detects unhealthy instances within a pool and automatically reroutes traffic to healthy instances until the unhealthy instances have been restored. Customers can enable Elastic Load Balancing within a single Availability Zone or across multiple zones for even more consistent application performance. Like all Amazon Web Services and features, Amazon CloudWatch and Elastic Load Balancing are available on a pay-as-you-go basis with no up-front fee, minimum spend or long term commitment. Auto Scaling is free to Amazon CloudWatch customers. Each instance launched by Auto Scaling is automatically enabled for monitoring and the Amazon CloudWatch monitoring charge will be applied. For more information on these new features and details on how to start using them, please see the resources listed below:
These have been among the most requested Amazon EC2 features by our customers. We hope they prove useful to you, and we look forward to your feedback.
Sincerely,
The Amazon Web Services Team
