Resource Quota
A limit set by AWS on the amount of resources a user can provision or use within their account.
Description
In the AWS (Amazon Web Services) ecosystem, a resource quota is a limit that AWS places on the usage of various resources to ensure fair distribution and management of its infrastructure. Each AWS account has predefined quotas for various services, which can include limits on the number of EC2 instances, IAM roles, S3 buckets, and more. These quotas are designed to protect the overall health of the AWS cloud environment and prevent any single user from monopolizing resources. Users can view their current quotas through the AWS Management Console and can request increases if necessary. For instance, a user running a startup might initially be limited to 20 EC2 instances but could request an increase to 50 as their application scales. Understanding and managing resource quotas is crucial for optimizing cloud resource usage and avoiding service interruptions or unexpected costs.
Examples
- An AWS account has a default limit of 5 Elastic Load Balancers (ELBs) per region.
- A user may be granted a quota increase from 100 to 200 Amazon RDS database instances to support a growing application.
Additional Information
- Resource quotas can vary by AWS service and region, so it's important for users to check their specific limits.
- AWS provides tools to monitor resource usage against quotas, allowing users to manage their resources effectively.
