Well-Architected Framework Pillars
Operational Excellence
It's a series of best practices to help with your architecture's organisation, Preparation, Operation, and Evolution of your architecture. Operational Excellence is composed of 5 design principles:
- ‣ Perform operations as code;
- ‣ Make frequent, small, reversible changes;
- ‣ Refine operations procedures frequently;
- ‣ Anticipate Failure;
- ‣ Learn from all operational failures;
Performance Efficiency
It's all about using your resources (IT and compute) in the best effective way. This pillar is composed of 5 design principles:
- ‣ Democratise advanced technologies;
- ‣ Go global in minutes;
- ‣ Use Serverless architectures;
- ‣ Experiment more often;
- ‣ Consider mechanical sympathy;
Security
This pillar's all about securing your architecture and your applications, including data. This pillar is composed of 7 design principles:
- ‣ Implement a strong identity foundation;
- ‣ Enable traceability;
- ‣ Apply security at all layers;
- ‣ Automate security best practices;
- ‣ Protect data in transit and at rest;
- ‣ Keep people away from data;
- ‣ Prepare for security events;
Cost Optimisation
It's all about running your applications at the best cost, delivering all business value. This pillar is composed of 5 design principles:
- ‣ Implement Cloud Financial Management;
- ‣ Adopt a consumption model;
- ‣ Measure overall efficiency;
- ‣ Stop spending money on undifferentiated heavy lifting;
- ‣ Analyse and attribute expenditure;
Reliability
This pillar focuses on maintaining your workloads running consistently, and helps to operate and test the workloads. Reliability has 5 design principles:
- ‣ Automatically recover from failure;
- ‣ Test recovery procedures;
- ‣ Scale horizontally to increase aggregate workload availability;
- ‣ Stop guessing capacity;
- ‣ Manage change in automation;
Sustainability
The sustainability pillar focuses on environmental impacts, especially energy consumption and efficiency. This pillar has 6 design principles:
- ‣ Understand your impact;
- ‣ Establish sustainability goals;
- ‣ Maximise utilisation;
- ‣ Anticipate and adopt new, more efficient hardware and software offerings;
- ‣ Use managed services;
- ‣ Reduce the downstream impact of your cloud workloads;
