Amazon Elastic Container Service (Amazon ECS) has increased the “Tasks in PROVISIONING state per cluster“ service quota to deliver a faster Cluster Auto Scaling experience. Customers who need to launch a large number of tasks (>300) in their Amazon ECS clusters will now see their cluster infrastructure scale faster.

Amazon ECS is a fully managed container orchestration service that makes it easier for you to deploy, manage, and scale containerized applications. ECS Capacity Providers is the infrastructure management capability designed to perform Cluster Auto Scaling by automatically scaling Amazon Elastic Compute Cloud (EC2) Auto Scaling groups on your behalf, so that you can focus on just running your tasks. ECS performs the scale-out operation iteratively for tasks being provisioned that require additional EC2 instances for placement. ECS can now increase capacity for 500 provisioning tasks in a single step, up from the previous 300, which translates to fewer scaling iterations, faster cluster autoscaling performance, and speedier task launches (e.g., 1000 tasks can now be placed ~20% faster).

The quota increase is now automatically enabled for you in Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD. To learn more, refer to the service quota and Cluster Auto Scaling user guide.
