What is the difference between cross-region and cross Availability Zone operations?

Question

Gowtham Hari Dhandapani · Accepted Answer

Cross-region operations refer to distributing application infrastructure across multiple geographically distinct AWS regions, enhancing availability, performance, and resilience. Cross Availability Zone operations, on the other hand, focus on deploying applications within a single region across multiple, physically isolated Availability Zones, each with its own power, cooling, and networking.

Regions are geographical or across continents. Zones are regional. Zones have number of availability zones created by Amazon. Operation or storage in different availability zones through EFS. Cross region access through EFS replica for both linux and windows. Single region cross availability zones is cheaper and low latency. Cross region is costliest.

ArunBalaji Ramadoss · Answer

Cross Region: Deploying applications and data across different geographical regions, such as multiple countries or continents. Each region has its own independent infrastructure and services, ensuring that a failure in one region won't impact the others. Cross availability zones: Within a region, there are typically multiple Availability Zones, which are physically separate data centers with independent power, cooling, and networking. Cross-AZ operations involve distributing resources across these different zones within the same region.
