Resilient Architecture II
Explore how to design resilient AWS multi-tier web applications by implementing Amazon RDS configurations, private subnet deployments with NAT gateways, and dynamic Auto Scaling policies. Understand how to meet strict recovery objectives, ensure security while enabling internet access for EC2 instances, and use CloudWatch for performance monitoring to optimize application architecture.
We'll cover the following...
