AWS Fargate increases default resource count service quotas
AWS Fargate, the serverless compute engine for containers that works with both Amazon Elastic Container Service (ECS) and Amazon Elastic Kubernetes Service (EKS), increases the default service quotas (also commonly known as limits) for On-Demand and Spot resource counts. You can now launch up to 500 concurrent ECS tasks and EKS pods running on Fargate On-Demand and 500 concurrent ECS tasks running on Fargate Spot, up from 100 and 250 respectively. These are default quotas for an account in a given AWS Region, but you can always raise these values by requesting a service quota increase.
