Cloud Global Infrastructure
Cloud providers like AWS, Google Cloud Platform (GCP), and Microsoft Azure have extensive global infrastructures to ensure their services are available, reliable, and fast.
Cloud providers organize their global infrastructure into hierarchical components to ensure scalability, high availability, and low latency.
Regions
A regions is a Geographical areas where cloud providers operate their data centers. Each region typically contains multiple isolated data centers (zones).
Regions are independent of one another, ensuring fault tolerance and data residency compliance. they Allow users to deploy resources close to their users or business operations. Provide redundancy and disaster recovery by enabling cross-region replication.
Zones
A zone is an isolated physical locations within a region, often referred to as Availability Zones (AZs) or simply zones.
Zones are connected by low-latency, high-speed networks. Each zone operates with independent power, cooling, and networking to minimize the risk of single-point failures. Typically, regions have at least 2–3 zones, depending on the provider.
Zones Enhance fault tolerance by enabling the deployment of applications across multiple zones in the same region. Provide high availability for mission-critical workloads.
Edge Locations
An edge location is a data centers or servers located closer to end users, outside primary regions and zones used primarily for content delivery, caching, and low-latency applications.
Serve as points of presence (PoP) for services like content delivery networks (CDNs) to Reduce latency by bringing content and services closer to end users and optimize global application performance for distributed workloads.
here a simple picture that demonstrate the Cloud Global Infrastructure.
By understanding these components, you can design resilient, scalable, and high-performing applications tailored to your needs.
