Google App Engine comes with predefined quotas. These default quotas can be changed via the hamburger menu, under IAM & Admin | Quotas. From this menu, we can review the current quotas and request an increase to these limits. You should be aware of the limits for each service as this can have an impact on your scalability.
For App Engine, we should be aware of the following quotas:
- Free quotas: For each application, you are allowed a certain amount of resources for free. This quota can be exceeded only for paid applications.
- Spending limits: This quota is used to control the limits you spend. It can be set by the project owner or billing administrator.
- Safety limits: This quota is set by Google to protect App Engine.
