Content Domain 3: Resilient Cloud Solutions

Task Statement 3.1: Implement highly available solutions to meet resilience and business requirements.

Knowledge of:

  • Multi-AZ and multi-Region deployments (for example, compute layer, data layer)

  • SLAs

  • Replication and failover methods for stateful services

  • Techniques to achieve high availability (for example, Multi-AZ, multi-Region)

Skills in:

  • Translating business requirements into technical resiliency needs

  • Identifying and remediating single points of failure in existing workloads

  • Enabling cross-Region solutions where available (for example, Amazon DynamoDB, Amazon RDS, Amazon Route 53, Amazon S3, Amazon CloudFront)

  • Configuring load balancing to support cross-AZ services

  • Configuring applications and related services to support multiple Availability Zones and AWS Regions while minimizing downtime

Task Statement 3.2: Implement solutions that are scalable to meet business requirements.

Knowledge of:

  • Appropriate metrics for scaling services

  • Loosely coupled and distributed architectures

  • Serverless architectures

  • Container platforms

Skills in:

  • Identifying and remediating scaling issues

  • Identifying and implementing appropriate auto scaling, load balancing, and caching solutions

  • Deploying container-based applications (for example, Amazon Elastic Container Service [Amazon ECS], Amazon Elastic Kubernetes Service [Amazon EKS])

  • Deploying workloads in multiple Regions for global scalability

  • Configuring serverless applications (for example, Amazon API Gateway, AWS Lambda, AWS Fargate)

Task Statement 3.3: Implement automated recovery processes to meet RTO and RPO requirements.

Knowledge of:

  • Disaster recovery concepts (for example, RTO, RPO)

  • AWS Backup and recovery strategies (for example, pilot light, warm standby)

  • Recovery procedures

Skills in:

  • Testing failover of Multi-AZ and multi-Region workloads (for example, Amazon RDS, Amazon Aurora, Route 53, CloudFront)

  • Identifying and implementing appropriate cross-Region AWS Backup and recovery strategies (for example, AWS Backup, Amazon S3, AWS Systems Manager)

  • Configuring a load balancer to recover from backend failure
