When I look back on the history of AWS and think about the launches that truly signify the fundamentally dynamic, on-demand nature of the cloud, two stand out in my memory: the launch of Amazon EC2 in 2006 and the concurrent launch of CloudWatch Metrics, Auto Scaling, and Elastic Load Balancing in 2009. The first […]

Earlier this year I told you about EC2 Fleet, an AWS building block that makes it easy for you to create fleets that are built from a combination of EC2 On-Demand, Reserved, and Spot Instances that span multiple EC2 instance types. In that post I showed you how to create a fleet and walked through […]

I recently told you about DynamoDB Auto Scaling and showed you how it uses multiple CloudWatch Alarms to automate capacity management for DynamoDB tables. Behind the scenes, this feature makes use of a more general Application Auto Scaling model that we plan to put to use across several different AWS services over time. The new […]

You can use to scale a collection of EC2 instances up and down based on a set of conditions that you define. Scaling out helps you to maintain the desired level of performance as demand for processing power increases; scaling in reduces costs during quiet periods. Today we are giving you additional control over the […]

helps you to build systems that respond to changes in the demand for compute power by launching additional instances or terminating existing ones. As I was thinking about this post, I thought it would be fun to deconstruct Auto Scaling to ensure that I (and you) have a full understanding of how it works and […]

I enjoy reading the blog posts that I wrote in the early days of AWS. Way back in 2009, I wrote a post to launch , , and . Here’s what I said at the time: “As soon as you launch some EC2 instances, you want visibility into resource utilization and overall performance. You want […]

I am pleased to be able to announce a set of updates and additions to . We are making a number of new services available including , , and VM Import. We are also enhancing the with support for and the Service Limits Report. As you may know, is an isolated AWS Region designed to […]

Earlier this month an AWS user named Andy emailed the following question to me: We’re interested in using the number of items in our sqs queue as criteria for autoscaling our ec2 workers. The 5 minute delay is really way too long for this application, it would have to keep track of the queue in […]

Auto Scaling is a key AWS service. You can use it to build resilient, highly scalable applications that react to changes in load by launching or terminating Amazon EC2 instances as needed, all driven by system or user-defined metrics collected and tracked by Amazon CloudWatch. Today we are enhancing Auto Scaling with the addition of […]

AWS Trusted Advisor provides you with advice and guidance to help you to use AWS safely, securely, and economically. Today we are making the Trusted Advisor even more useful, with support for additional service limit checks and for CloudTrail in additional Regions. Service Limit Checks Many AWS services are configured with per-account “soft” limits on […]
