Domain 3: Continuous Improvement for Existing Solutions

AWS Solutions Architect Professional (SAP-C02) · this domain is approximately 25.0% of the exam · 0 practice questions.

Continuous Improvement for Existing Solutions is the SAP-C02 domain that focuses on evolving already-deployed workloads to be more reliable, performant, cost-efficient, or secure without introducing unnecessary disruption. It draws heavily on the AWS Well-Architected Framework and its six pillars, requiring candidates to identify architectural weaknesses and propose targeted remediations. Common scenarios involve migrating monolithic applications toward microservices, right-sizing compute resources based on CloudWatch metrics, and improving resilience by introducing auto-scaling or multi-AZ deployments to previously single-point-of-failure architectures. Candidates should understand that improvement is iterative and evidence-based, not a one-time redesign.
