Azure Paired Regions

Each Azure region is paired with another region within the same geography, together making a regional pair. The exception is Brazil South, which is paired with a region outside its geography.

Understand Azure Global Infrastructure

Geographies (Geos)

A geography is a discrete market, typically containing two or more regions, that preserves data residency and compliance boundaries. Geographies allow customers with specific data-residency and compliance needs to keep their data and applications close. Geographies are fault-tolerant to withstand complete region failure through their connection to Microsoft dedicated high-capacity networking infrastructure. Geos examples: US, Europe, Asia Pacific, Japan, Brazil, Australia, China. Learn more  >


A region is a set of datacenters deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network. With more global regions than any other cloud provider, Azure gives customers the flexibility to deploy applications where they need to. Azure is generally available in 40 regions around the world, with plans announced for 10 additional regions

Availability Zones

Availability Zones are physically separate locations within an Azure region. Each Availability Zone is made up of one or more datacenters equipped with independent power, cooling, and networking. Availability Zones allow customers to run mission-critical applications with high availability and low-latency replication.

Microsoft Azure gets a new Logo, new Tagline

Microsoft has changed logo for the Microsoft Azure cloud.

A new tagline: Azure. Cloud for all

Old Azure, New Azure.

Azure has a web interface called the Management Portal that allows administrators to access and administer Azure features. Currently there are 2 versions of Management Portal:

ASM – Azure Service Management (aka Old Azure) =>
ARM – Azure Resource Manager (aka New Azure) =>

Azure Services

Microsoft Azure is Microsoft’s platform for the public cloud. Azure groups services into categories in the Management Portal.

Here’s a big-picture view of the available services and features in Azure.

Most commonly-used categories:

  • Compute
  • Networking
  • Storage
  • Mobile
  • Databases
  • Web
  • Internet of Things
  • Big Data
  • Artificial Intelligence
  • DevOps


Cloud Computing Basics – IaaS, PaaS, SaaS

Infrastructure as a Service (IaaS) – servers, storage, network and operating systems – as an on-demand service. Rather than purchasing servers, software, datacenter space or network equipment, clients instead buy those resources as a fully outsourced service on demand.

Platform as A Service (PaaS ) can be defined as a computing platform that allows the creation of web applications or software quickly and easily and without the complexity of buying and maintaining the software and infrastructure underneath it.

Software as a Service (SaaS) is software that is deployed over the internet. In a SaaS you are provided access to application services installed at a server. You don’t have to worry about installation, maintenance or coding of that software. An obvious example of SaaS is Microsoft’s Office 365, where the applications run remote from the user’s computer.

Azure Manifesto

Microsoft: “We believe that the success made possible by the cloud must be accessible to every business and every organization—small and large, old and new.”
