Q

Design for Failure

A

In cloud architecture, applications are designed to handle failures gracefully rather than trying to prevent every possible failure. This involves using redundancy, automated backups, and distributed components to ensure system availability and resilience in the face of failures.

20
Q

Decouple Components versus Monolithic Architecture:

A

Cloud architecture encourages breaking down applications into smaller, loosely coupled components. This allows for independent development, deployment, and scalability of each component, leading to increased flexibility and easier maintenance.

21
Q

Implement Elasticity

A

Elasticity refers to the ability to automatically scale resources up or down based on demand. Cloud architecture should be designed to take advantage of this elasticity, ensuring that applications can handle varying workloads efficiently and cost-effectively.

22
Q
