When working with cloud service providers, you may notice that at some point there are service / quota limitations.
Some limits are per account / subscription; some of them are per region and some limits are per pricing tier (free tier vs billable).
Here are some of the most common reasons for service / quota limitations:
- Performance issues on the cloud provider’s side – loading a lot of virtual machines on the same data center requires a lot of resources from the cloud provider
- Avoiding spikes in usage – protect from a situation where one customer consumes a lot of resources that might affect other customers and might eventually cause denial of service
For more information about default cloud service limits, see:
- AWS Service Limits:
https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html - Azure subscription and service limits, quotas, and constraints:

Default limitations can be changed by contacting the cloud service provider's support and requesting a change to the default limitation.
