Summary
In this chapter, we explored critical pillars of the AWS Well-Architected Framework such as operational excellence, reliability, security, efficiency, and cost optimization, specifically through the lens of architecting resilient cloud solutions. While each of these pillars plays a crucial role in enhancing resilience, they are interconnected and must be addressed in tandem, as we learned in this chapter. Well-Architected provides continuously updated tactical guidance on using AWS services purposefully to eliminate undifferentiated tasks unrelated to core business goals. We discussed leveraging reference architectures, infrastructure automation, robust monitoring, secure design principles, and cost-effective operations to build reliable and resilient architectures.
The key takeaways included using AWS managed services to reduce heavy lifting, automating deployments and procedures, conducting reviews to incrementally improve, scaling to demand, understanding system health...
