Well Architected Framework WAF

• WAF: https://aws.amazon.com/blogs/aws/

Design to enable everyone build secure and reliable application

• Stop guessing capacity
• Test System at production scale
• Automate as much as you can
• Evaluate architecture based on changing requirement
• Plan for game day or peak traffic

Well Architected Tool

AWS Service Track performance and evolve architecture over time

• Need to answer some questions to generate a report
• Tool to help guide as solution Architect

Design Principal

• Scalable : Horizontal & Vertical
• Disposable: easy to configure
• Automation: Serverless architecture
• Loose Coupling: Fault tolerant
• Think in Service not Server

5 Pillars of WAF

1. Operational Excellence

Run & Monitor business process & continuously improve supporting process & procedure

• Infrastructure as code: aws cloud formation with help of config
• Deploy Often: Incremental small changes
• Refine process & automate as much as possible
• Anticipate failure & learn from it
• Annotate Document: Clean and proper document

2. Security

Ability to Protect System, Information & Assets through risk assessment & mitigation.

• Strong Access & Identity Management
• Enable Traceability
• Apply security as all level
• Automate security best practice
• Protect Data in Rest & Transit
• Keep people away from Data
• Prepare for security events & recovery

3. Reliability

Ability of a system to recover from disruption, dynamically acquire resources to meet demand & mitigate misconfiguration

• AWS Trusted Advisor & AWS Service Quotas
• Test recovery procedure
• Automatic recovery from failure
• Scale automatically to handle load
• Stop guessing capacity
• Mange change with automation

4. Performance Efficiency

Ability to Use resource efficiently & maintain that efficiency as demand grows

• Democratize advanced services
• Go global in minute
• Serverless Architecture
• Experiment more often
• Be top of the game

5. Cost Optimization.

Ability to monitor, track & Control where money is spend

• Pay for what you need
• Measure overall efficiency
• Analyze expanses
• Use Manged service to reduce cost of ownership
