AWS Certified Solutions Architect - Professional

Some organizations maintain both on-premises infrastructure and cloud workloads. Hybrid architectures require secure and reliable connectivity between environments.

AWS provides networking and connectivity options that can support hybrid applications. Architects must consider network design, routing, security, bandwidth, latency, DNS, and data transfer requirements.

A hybrid architecture should clearly define which workloads remain on-premises and which are deployed in AWS, while ensuring that required systems can communicate securely.

Advanced Networking

Networking becomes more complex as AWS environments grow. Professional solutions architects need to understand VPC architecture, routing, private connectivity, load balancing, DNS, network security, and multi-VPC environments.

Large organizations may require centralized connectivity between multiple VPCs and accounts. They may also need connections between AWS and corporate data centers.

Network architecture should provide appropriate isolation, performance, scalability, and security while remaining manageable for operations teams.

Data and Database Architecture

Selecting the correct data storage and database technology is an important architectural responsibility.

AWS provides relational databases, NoSQL databases, object storage, file storage, caching, and specialized data services.

Architects need to consider data structure, query patterns, performance, availability, consistency, scalability, backup, disaster recovery, and cost.

Complex applications may use multiple database technologies rather than relying on a single database.
