Zorluk: OrtaAWS Global Infrastructure

A healthcare provider is deploying a telemedicine application on AWS. The application must be designed for high availability and fault tolerance, ensuring that if a physical data center experiences a power outage, the application continues to run without downtime. The system must also support synchronous database replication within the same geographical territory.

Which AWS Global Infrastructure component should the company use to distribute their application instances to meet these requirements?

  1. Availability ZonesCevap
  2. B
    AWS Regions
  3. C
    AWS Edge Locations
  4. D
    AWS Outposts

Cevap

Availability Zones
Availability Zones are the correct choice because they are physically isolated locations within an AWS Region, designed to protect applications from local power or cooling outages while remaining close enough to support synchronous data replication and high availability.

Adım Adım Çözüm

1
Identify the core requirement for high availability and physical redundancy within a single geographical territory.
The requirement demands physical isolation to survive localized power outages while supporting synchronous replication (low latency).
This helps narrow down infrastructure options that are close enough for low latency but physically isolated.
2
Compare AWS Regions, Availability Zones, Edge Locations, and AWS Outposts.
Availability Zones are distinct groups of physical data centers within a Region, connected by low-latency links. AWS Regions represent separate geographic territories. Edge Locations cache content but do not run applications. AWS Outposts are on-premises.
Choosing the correct component ensures the system meets the high availability and synchronous replication requirements.
