Description: App Engine quotas are limits set by cloud service providers that regulate the amount of resources an application can consume on cloud platforms. These quotas are essential to ensure fair resource usage among all users and to prevent abuses that could affect the stability and performance of the service. Quotas can cover various aspects, such as the number of application instances, CPU usage, memory, network requests, and storage operations. By establishing these limits, cloud providers allow developers to plan and optimize their applications, ensuring they do not exceed available resources and maintaining consistent performance. Additionally, quotas help administrators monitor resource usage and make informed decisions about scalability and cost management. If an application reaches its quota limits, the service may be temporarily interrupted, highlighting the importance of proper resource management. Quotas are an integral part of cloud application architecture, as they allow developers to focus on building applications without worrying about the underlying infrastructure while ensuring that the execution environment is safe and efficient.
