AWS Certified Solutions Architect - Professional

An architecture should avoid unnecessary single points of failure. Resources can be distributed across multiple Availability Zones or Regions when business requirements justify the additional complexity and cost.

Disaster Recovery and Business Continuity

Disaster recovery is an important component of professional cloud architecture. Organizations need strategies for protecting applications and data against infrastructure failures, regional disruptions, accidental deletion, and other incidents.

AWS provides several approaches to disaster recovery, including backups, replication, standby environments, and multi-Region architectures.

Architects need to understand Recovery Time Objective (RTO) and Recovery Point Objective (RPO) and select recovery strategies according to business requirements.

The appropriate disaster recovery architecture depends on factors such as application criticality, acceptable downtime, data loss tolerance, budget, and operational complexity.

Cloud Migration

Many organizations are migrating traditional data center workloads to AWS. Solutions architects play a key role in evaluating existing applications and selecting appropriate migration strategies.

Possible approaches include rehosting, replatforming, refactoring, repurchasing, retaining, or retiring workloads.

The correct strategy depends on application architecture, modernization goals, budget, technical dependencies, performance requirements, and business priorities.

Professional-level AWS knowledge helps architects plan migration roadmaps and design target cloud architectures that support long-term business objectives.
