Monitor and manage quotas
Managing service quotas is crucial for system stability as your business grows on the cloud. Each Alibaba Cloud service has default limits on resource usage, such as the number of ECS instances, SLB connections, and RDS instances. Failure to monitor and manage these quotas can lead to service interruptions, auto scaling failures, and performance degradation.

Bad practices
Failing to configure monitoring for quota usage.
Failing to set alerts for hard limits, such as API call frequency.
Configuring alerts without a response plan.
Monitoring only some service quotas while ignoring others.
Ignoring quota consistency across multi-region deployments.
Assume the quota request can be completed quickly.
Implementation guide
Obtain current resource usage, such as the number of instances and connections.
Obtain service quota information:
Use Alibaba Cloud Quota Center.
You can view Alibaba Cloud service documentation.
Use the command-line interface (CLI) or an API to query quota limits.
Set up quota monitoring and alerting.
In Quota Center, create monitoring alerts for specific quotas based on metrics such as usage rate, remaining availability, or total usage.
Periodically check the quota history to understand resource growth trends.
If a quota is insufficient, submit a ticket to request an increase.
