Which Deployment Area within a Region for Fault-Tolerant and Highly Available Applications in India?
Question
You are asked to deploy applications so that they are fault-tolerant and highly available.
Since the customers are based only in India, you plan to use only one region. Which deployment area within a region would you use to deploy the applications?

A. B. C. D.Correct Answer: A.
Option A is correct.
Zones are a deployment area within a region, and Zones can be utilized for deploying applications in a way that they are fault-tolerant and highly available.
Option B is incorrect.
If an application is deployed in a particular data center, and the data center is impacted by, say power failure or some calamity, the application would also go down.
Hence, opting for a data center would not be the right choice.
Option C is incorrect.
Sub-Region is an invalid option.
Option D is incorrect.
Datazone is an invalid option.
https://cloud.google.com/docs/geography-and-regions#regions_and_zonesIf you are planning to deploy applications so that they are fault-tolerant and highly available in a single region, the recommended deployment area would be Zones.
A Zone is a distinct location within a region that is designed to be isolated from failures in other zones. Each zone has its own power supply, networking, and cooling systems, which makes it possible to isolate failures to a particular zone without affecting the availability of applications in other zones.
By deploying your applications in different zones within a single region, you can ensure that your applications remain available even if there is a failure in one zone. This is because requests can be automatically redirected to healthy instances in other zones.
Datacenters and Datazones are not valid deployment areas within a region. A Datacenter is a physical location that houses computer systems and other equipment, and a Datazone is a term that is not commonly used in the context of cloud computing.
A Sub-Region, on the other hand, is a collection of regions that are geographically close to each other and connected by a high-speed network. While deploying applications across sub-regions can provide additional fault tolerance and availability, it also introduces additional complexity and cost. Therefore, in this case, deploying applications across different zones within a single region is the recommended approach.
