Building a resilient architecture
Design for failure and nothing will fail. Having a resilient architecture means that your application should be available for customers while also recovering from failure. Making your architecture resilient includes applying best practices to recover your application from increased loads due to more user requests, malicious attacks, and architectural component failure. Resiliency needs to be used in all architectural layers, including infrastructure, application, database, security, and networking. A resilient architecture should recover within the desired amount of time.
To make your architecture resilient, you need to define the time of recovery and consider the following points:
- Identify and implement redundant architectural components wherever required.
- Identify and implement backup and disaster recovery plans within a defined Recovery Time Objective (RTO) and Recovery Point Objective (RPO)
- Understand when to fix versus...
