A Hybrid Cloud combines on-premises infrastructure (private cloud) with public cloud services such as AWS, Azure, or Google Cloud.
The two environments are connected so that data and applications can work across both environments.
An Availability Zone is one or more physically separate data centers within an AWS Region, designed to be isolated from failures in other AZs.
AZs within the same Region are connected through AWS's private, low-latency, high-bandwidth network.
This allows applications to communicate between AZs while maintaining high availability and fault tolerance.
An AWS Local Zone is an extension of an AWS Region that places AWS infrastructure closer to end users in a specific geographic area.
It solves the problem of high latency when users are far away from the main AWS Region.
Example:
Suppose your application is hosted in the Mumbai Region, but users are located in another distant city. A Local Zone closer to those users can run supported workloads nearby, reducing network latency.
