AWS Certified Solutions Architect Exam Guide – Chapter-1

April 25, 2021 comments off

Understand the global infrastructure.
AWS provides a highly available technology infrastructure platform with multiple locations worldwide. These locations are composed of regions and Availability Zones. Each region is located in a separate geographic area and has multiple, isolated locations known as Availability Zones.

Understand regions.
An AWS region is a physical geographic location that consists of cluster of data centers. AWS regions enable the placement of resources and data in multiple locations around the globe. Each region is completely independent and is designed to be completely isolated from the other regions. This achieves the greatest possible fault tolerance and stability. Resources aren’t replicated across regions unless organizations choose to do so.

Understand Availability Zones.
An Availability Zone is one or more data centers within a region that are designed to be isolated from failures in other Availability Zones. Availability zones provide inexpensive, low latency network connectivity to other zones in the same regions. By placing resources in separate Availability Zones, organizations can protect their website or application from a service disruption impacting a single location.

Understand the hybrid deployment model.
A hybrid deployment model is an architectural pattern providing connectivity for infrastructure and applications between cloud based resources and existing resources that are not located in the cloud.
