AWS Well-Architected Framework Pillars

Pillar 1 : Operational Excellence

The ability to support development and run workloads effectively, gain insight into operations and to continuously improve supporting procedures and processes to deliver business value.

Pillar 2 : Security

The security pillar centres on the ability to protect systems, data and provides assets to take advantage of cloud technologies to improve security. The AWS Well-Architected pillar provides an overview of design principles, best practices and questions you need to ask when considering the security of your AWS infrastructure.

  • How do you manage people and machine identities?
  • How do you manage permissions?
  • How do you detect and investigate security events?
  • How do you protect network resources?
  • How do you protect compute resources?
  • How to you define and classify data?
  • How do you protect data at rest?
  • How do you protect your data in transit?
  • How do you anticipate, respond to, and recover from incidents?

Pillar 3 : Reliability

The reliability pillar focuses on the ability of a workload to perform its intended function correctly and consistently when it’s expected to. This includes the ability to operate and test the workload through its total lifecycle.

  • How do you plan your network topology?
  • How do you design your workload service architecture?
  • How do you design interactions in a distributed system to prevent failures?
  • How do you mitigate or withstand failures?
  • How do you monitor workload resources?
  • How do you design workloads to adapt to changes in demand?
  • How do you implement change?
  • How do you back up data?
  • How do you isolate faults to protect your workloads?
  • How do you design to withstand component failures?
  • How do you test reliability?
  • What is your disaster recovery plan?

Pillar 4 : Performance Efficiency

Examines the ability to use cloud computing resources to meet system requirements efficiently and to maintain that efficiency as demand changes and new technologies emerge.

  • How do you select your compute solution?
  • How to choose a database on AWS?
  • How do you select your database solution?
  • How do you configure your networking solution?
  • How do you evolve your workload to leverage new releases?
  • How do you monitor resource performance?
  • How do you use tradeoffs to improve performance?

Pillar 5 : Cost Optimization

The ability to select and run components of business systems at the lowest price point.

  • How do you govern usage?
  • How do you monitor usage and cost?
  • How do you decommission resources?
  • How do you evaluate cost when you select services?
  • How do you meet cost targets when selecting resource type, size or number?
  • How do you use pricing modules to reduce cost?
  • How do you plan for data transfer charges?
  • How do you manage demand, and supply resources?
  • How do you evaluate new services?
