Allow for evolutionary architectures:

As you use operations procedures, look for opportunities to improve them. As you evolve your workload, evolve your procedures appropriately. Set up regular game days to review and validate that all procedures are effective and that teams are familiar with them.

Drive architectures using data:

Successful evolution of operations is founded in: frequent small improvements; providing safe environments and time to experiment, develop, and test improvements; and environments in which learning from failures is encouraged.

Test systems at production scale:

Share lessons learned across teams to share the benefits of those lessons. Analyze trends within lessons learned and perform cross-team retrospective analysis of operations metrics to identify opportunities and methods for improvement. Implement changes intended to bring about improvement and evaluate the results to determine success.

AWS Shield is a managed Distributed Denial of Service (DDoS) protection service that safeguards web applications running on AWS.

Tradeoffs can increase the complexity of your architecture and require load testing to ensure that a measurable benefit is obtained.
