Design Resilient Architectures:

High Availability and Disaster Recovery:

• Designing systems that are highly available and can withstand failures using AWS services.
• Implementing multi-AZ (Availability Zone) and multi-region architectures.

Elasticity and Scalability:

• Designing scalable solutions that automatically adjust capacity based on demand.
• Using Auto Scaling, Elastic Load Balancing (ELB), and AWS Lambda for elasticity.

Fault Tolerance:

• Implementing fault-tolerant solutions using services such as Amazon S3, Amazon RDS, and Amazon Route 53.

Design Secure Applications and Architectures:

Security and Compliance:

• Implementing AWS Identity and Access Management (IAM) for access control.
• Designing solutions that comply with security best practices, such as encryption and secure networking.

Data Protection:

• Implementing encryption for data at rest and in transit using AWS services like AWS KMS (Key Management Service) and Amazon S3.
• Managing and securing data using AWS Backup and AWS Cloud Trail.

Design Cost-Optimized Architectures:

Cost Management:

• Designing cost-effective solutions by selecting the right AWS services and configurations.
• Implementing cost monitoring and optimization using AWS Cost Explorer and AWS Budgets.

Resource Utilization:

• Choosing appropriate instance types and storage options to minimize costs.
• Using Reserved Instances and Savings Plans to optimize pricing.

Define Operationally Excellent Architectures:

Monitoring and Logging:

• Implementing monitoring and logging solutions using AWS CloudWatch and AWS Cloud Trail.
• Designing systems for operational efficiency and troubleshooting.

Automation:

• Automating deployment and management tasks using AWS CloudFormation, AWS OpsWorks, and AWS Systems Manager.
