What is Resource quotas and why does it matter in DevOps?

Resource quotas are a critical feature in Kubernetes that allow administrators to limit the amount of resources that a particular namespace can use. These quotas help ensure fair distribution of resources such as CPU, memory, and storage among different teams or applications within a cluster. In a DevOps environment, understanding and implementing resource quotas is essential for maintaining performance stability and avoiding resource contention across various deployments.

When teams deploy applications in a shared infrastructure, resource quotas help monitor and manage usage effectively. They prevent scenarios where one team consumes excessive resources, potentially impacting the performance of applications belonging to other teams. Resource quotas also facilitate strategic resource planning and can enforce organizational policies regarding resource utilization.
