Enhancing auto scaling resilience by tracking worker utilization metrics
A resilient auto scaling policy requires metrics that correlate with application utilization, which may not be tied to system resources. Traditionally, auto scaling policies track system resource such as CPU utilization. These metrics are easily available, but they only work when resource consumption correlates with worker capacity. Factors such as high variance in request processing time, mixed instance types, or natural changes in application behavior over time can break this assumption.
Building resilient multi-Region Serverless applications on AWS
This post presents architectural best practices for building resilient serverless applications, demonstrated through a multi-Region serverless authorizer implementation.
Using zonal shift with Amazon EC2 Auto Scaling
This post is written by Michael Haken, Senior Principal Solutions Architect, AWS Today, we’re announcing support for zonal shift in Amazon EC2 Auto Scaling. Zonal shift allows you to rapidly recover from application impairments in a single Availability Zone (AZ) impacting your Auto Scaling Group (ASG) resources. In this post, we describe how performing an […]
