  • Evolve: Continuously evaluate and improve the operational efficiency of AWS resources

Performance Efficiency

• Focuses on using computing resources efficiently to meet system requirements
• Key concepts:
  • Compute Resources: Select the right resources to meet system requirements
  • Storage: Choose the right storage options for the workload
  • Database: Select the right database instance type and configuration
  • Space: Optimize the use of storage and database resources

Reliability

• Focuses on designing and operating reliable workloads to ensure business continuity
• Key concepts:
  • Foundations: Ensure a reliable foundation for workloads through selecting the right AWS regions and availability zones
  • Workload Architecture: Design workloads to be resilient and fault-tolerant
  • Recovery: Implement disaster recovery strategies to minimize downtime

Cost Optimization

• Focuses on optimizing costs to achieve business objectives
• Key concepts:
  • Cost-Aware Architecture: Design architectures that minimize costs
  • Resource Utilization: Optimize resource utilization to reduce waste
  • Expenditure Awareness: Establish cost-aware culture and provide cost transparency
  • Optimizing Over Time: Continuously evaluate and optimize costs over time

Security

• Focuses on protecting sensitive data and workloads in the cloud
• Key concepts:
  • Identity and Access Management (IAM): Manage access and permissions for users and resources
  • Detective Controls: Implement monitoring and logging to detect security incidents
  • Infrastructure Security: Protect AWS resources with security groups and network ACLs
  • Data Protection: Protect data at rest and in transit

Overview of AWS Well-Architected Framework

• A set of best practices for designing and operating reliable, secure, and high-performing workloads in the cloud

Operational Excellence

• Focuses on running and managing AWS resources to deliver business value
• Key concepts: operations, evolve, and learn
• Best practices:
• Implement a culture of experimentation and learning
• Automate repetitive tasks and processes
• Monitor and analyze performance metrics to make data-driven decisions

Reliability

• Focuses on designing and implementing systems that can recover from failures and scaling to meet demand
• Key concepts: fault tolerance, scaling, and recovery
• Best practices:
• Use distributed architectures to reduce single points of failure
• Implement auto-scaling and load balancing to handle changing demand
• Use data replication and backup strategies to ensure system recovery

Security

• Focuses on protecting sensitive data and systems from unauthorized access and malicious activity
• Key concepts: identity and access management, detection, and protection
• Best practices:
• Use IAM roles and permissions to manage access to resources and data
• Implement encryption at rest and in transit to protect data
• Monitor and analyze security logs and metrics to identify and respond to security threats

Cost Optimization

• Focuses on optimizing costs by selecting the most appropriate resources and pricing models
• Key concepts: right sizing, Reserved Instances, and cost allocation
• Best practices:
• Use cost estimation and tracking tools to manage costs
• Implement cost allocation and tagging to track costs by department or project
• Consider Reserved Instances and spot instances for cost savings

Performance Efficiency

• Focuses on selecting the most appropriate resources and optimizing system performance
• Key concepts: compute resources, storage, and database
• Best practices:
• Use right-sized resources and instance types to optimize system performance
• Optimize database performance and architecture for workloads
• Implement caching and content delivery networks to improve system performance
