Región de Azure
Las regiones de Azure son ubicaciones geográficas donde Microsoft Azure opera centros de datos.
Ofrecen a las organizaciones la flexibilidad de implementar sus recursos en regiones específicas para
optimizar el rendimiento, el cumplimiento normativo y la disponibilidad.
Una región es un conjunto de centros de datos implementados dentro de un perímetro de latencia definido
y conectados a través de una red regional dedicada de baja latencia.
Con más regiones globales que cualquier otro proveedor de nube, Azure ofrece a los clientes la flexibilidad
de implementar aplicaciones donde las necesiten. Azure está disponible en 52 regiones de todo el mundo,
y se han anunciado planes para 6 regiones adicionales.

Microsoft Azure cuenta actualmente con más de 60 regiones operativas y 19 más en desarrollo, lo que
significa que la empresa dispondrá de un total de 78 regiones a corto plazo. Dentro de cada región de
Azure hay de una a tres ubicaciones físicas únicas, denominadas zonas de disponibilidad, que ofrecen un
alto tiempo de actividad para proteger los datos y las aplicaciones de fallos en el centro de datos.
Actualmente, Microsoft Azure tiene 113 zonas de disponibilidad operativas y 51 adicionales en desarrollo,
lo que significa que la empresa tendrá un total de 164 zonas de disponibilidad existentes en el corto plazo.
Cada zona de disponibilidad de Microsoft Azure se crea a partir de uno o más centros de datos equipados
con sistemas de alimentación, refrigeración y redes independientes. La separación física de las zonas de
disponibilidad dentro de un vecindario protege las aplicaciones y los datos de interrupciones en las
instalaciones.

What is Region Pairing?
The reason I start here is that Azure contains a feature that’s unique among the large three cloud providers.
It’s the concept of “region pairing.” Region pairing is that the relationship between two Azure regions within
an identical geographical area to supply geographically redundant solutions. Azure’s paired regions are
prewired with high bandwidth connectivity between them.
Azure operates in several geographies worldwide, and within given geography or geopolitical boundary,
each region is deployed together with another paired region. Some exceptions exist, like Brazil, which is
paired with South Central US, but these are edge cases. So, for instance, in the US, Microsoft pairs Virginia
(called East US 2) with Iowa (called Central US).
So, if you’re in East US 2 and a disaster recovery (DR) failover has to occur, you’re still within inexpensive
proximity to your secondary region and warranted of a high level of service from a latency perspective.
Contrast this with the first Virginia region, East US, which pairs with West US (California), and you’re faced
with a far higher latency should your environment have to failover.
Region Pairs
Each Azure region pairs with another region within the same geography, together making a regional
pair.
Azure serializes platform updates so only one region is updated at a time.
Azure Regions in a Pair have direct connections that bring additional benefits to use them together.
Each Azure Region in a pair is always located greater than 300 miles apart when possible.
Examples of region pairs are West US paired with East US, South-East Asia paired with East Asia.

Geographies
Geography is a discrete market, typically containing two or more regions, that preserves data residency and
compliance boundaries.
It allows customers with specific data-residency and compliance needs to keep their data and applications
close. However, they are fault-tolerant to withstand complete region failure through their connection to our
dedicated high-capacity networking infrastructure.

Azure Availability Zone
Azure Availability Zones is a high-availability offering that protects your applications and data from
datacenter failures.
These are unique physical locations within an Azure region. Each zone is made up of one or more
data centers equipped with independent power, cooling, and networking.
The physical separation of Availability Zones within a region protects applications and data from
datacenter failures.
Zone-redundant services replicate your applications and data across Azure Zones to protect from
single-points-of-failure.
Not every region has support for Availability Zone Azure. The examples of Availability
Zones are Central US, East US 2, West US 2, West Europe, France Central, North Europe &
Southeast Asia
With Availability Zones, Azure offers industry best 99.99% VM uptime SLA(Service Level

It provides redundancy for your virtual machines.
An Availability set spreads your virtual machines across multiple fault domains and update
domains.
If you want to leverage Microsoft’s 99.95% SLA from Microsoft you must place your VMs inside
availability set except your VMs are having premium storage.
An Update Domain and Fault Domain is assigned to each VM in Availability Set by Azure platform.

Availability Set vs Availability Zone
Availability Sets takes the virtual machine and configures multiple copies of it. Each copy is isolated within a
separate physical server, compute rack, storage units and network switches within one datacentre within an
Azure Region.
When you create your virtual machine you’ll be able to specify the provision Set, you can’t change it or
move it in or out of an Availability Set after creation. If you wanted to create changes you’d start again and
recreate the virtual machine. And Availability Sets only apply to virtual machines, they can’t be used for the
other kind of resources within Azure.
Using an Availability Set takes your acceptable downtime to around 22 minutes a month. Which could be a
vast improvement over the one virtual machine deployment.

The next level of availability for your virtual machines within Azure is Availability Zones. With Availability
Zones utilised your acceptable downtime a month moves to but 5 minutes as you’ve got a 99.99% SLA.
With Availability Zones, you’re setting out to use zone-aware services. Your workload is opened up across
the various zones that compose an Azure region. An Azure region is formed from multiple datacentres and
every zone is formed from one or more datacentres. Each datacentre is provided with independent power,
cooling and networking.
When should I use an Available Zone vs Set?
When building your workload in Azure it’s important you concentrate on carefully how you’re to
create availability in your virtual machine infrastructure. There are some factors you ought to consider when
choosing whether to use availability sets or zones.
Cost
When creating an availability zone there’s a further bandwidth cost for data moving into and out of a zone.
it’s however quite minimal, at around 1 pence per GB, but it quickly builds up with workloads that have a
high data churn.
Storage
Where availability zones support managed disks, availability sets don’t directly. This doesn’t mean that
managed disks that are attached to VMs in availability sets don’t seem to be as available, they’re still

Availability
As availability sets and availability zones are two different services, they both include different SLA (service
level agreements). The SLA is defined as a percentage, as specifies the guaranteed uptime of your
compute or service. This doesn’t include your application or overall workload, but the underlying azure
service running it. Where availability sets guarantee a 99.95% uptime, availability zones guarantee a
99.99% uptime. Although this doesn’t appear to if much, this (on paper) is the difference between around 5
hours of cumulative downtime over one year compared to under 1 hour of cumulative downtime.
Microsoft Azure’s regions vs. Amazon
Availability Zones
For most customers, the differences between these approaches won’t matter an excessive amount of, says
Jared Wray, former CTO of CenturyLink’s cloud and now an entrepreneur. He says the foremost common
deployment method for enterprise apps migrating to the cloud is to host them in one region and back it up
to a different (an active-passive setup). In AWS’s case, is done to bushed one region across two AZs. In
Microsoft or Google’s case, another region would be used. Cloud providers offer ok latency across their
regions for many workloads, Wray says.
Where AZ’s shine, he notes, is that if you wish a low-latency backup or an active-active backup. AZs within
the identical region have fast dedicated connections, which are ideal for these apps.
AZs include some downsides though, Wray adds. If an AZ has an outage, many purchasers have designed
their workloads failover to a different AZ in this same region. If all of the purchasers within the downed AZ
transfer workloads to the healthy AZ, that would theoretically create a crowded AZ, which could impact
performance.
To help alleviate this issue, cloud vendors are continually adding new regions. Just this month Amazon
launched a replacement region in Ohio to assist offload capacity from its Virginia region and satisfy
increased demand for its services. Microsoft brought on two new government regions this month too.

Azure Fault Domains
Azure Fault domains define the group of virtual machines that share a common power source and
network switch.
Each and every fault domain contains some racks and each rack contains a virtual machine.
Each of these Azure Fault domains shares a power supply and a network switch.
All the resources in the fault domain become unavailable when there is a failure in the fault domain.
You should place your VMs in such a way that each fault domain gets one web server, one database
server, and like that.

Azure Update domain and Fault Domain
Azure update domain and fault domain are two logical groupings of Azure resources that are designed to
help you distribute your workloads across different physical hardware and software components. This can
help to reduce the risk of downtime due to hardware or software failures or updates.
Virtual machines get updated domains automatically once they are put inside the availability set.
All virtual machines within that update domain will reboot together.
They are used for patching of the virtual machines.
Only one updated domain can be updated at a time.
Check Out: What is Azure Virtual Machine Scale Set (https://k21academy.com/microsoft-azure/az104/virtual-machine-scale-set-in-microsoft-azure/)?
How many Fault Domains and How many Update Domains we can
have?
In the Azure Service Management (ASM) portal, we have two Fault domains and 5 update domains.
In the Azure Resource Manager(ARM) portal, we have three Fault domains and 5 update domains
but we can upgrade our update domains from 5 to 20.
VMs are assigned sequentially in the update domains and fault domains.

Key Points To Remember
You need to create virtual machines in the same resource group as the availability set.
Only one virtual machine can only be in one availability set.
Virtual machines can be assigned availability set only during their creation of it.

SLA(Service Level Agreement) for VM:
For all Virtual Machines that have two or more instances deployed in the same Availability Set, Azure
guarantees you will have Virtual Machine Connectivity to at least one instance at least 99.95% of the
time.
For any Single Instance Virtual Machine using premium storage for all disks, Azure guarantees you
will have Virtual Machine Connectivity of at least 99.9%.

Frequently Asked Questions(FAQs)
Q1. What is difference between update domain and fault domain in Azure?
The difference between update domain and fault domain are:
Update domains are used to isolate resources for maintenance and updates, while fault domains
are used to isolate resources from hardware and software failures
All of the resources in an update domain must be capable of being updated or rebooted
simultaneously by Azure. However, fault domains must not be so big that all of the resources
inside it become unavailable in the event of a failure; rather, they must be big enough to isolate
resources from failures.

Respuesta 1. Sí.
Respuesta 2. Sí, esto solo aplica si tiene varios servidores.
Una máquina virtual de una sola instancia en un conjunto de disponibilidad debe usar un SSD
Premium o un disco Ultra para todos los discos del sistema operativo y de datos para cumplir
con el Acuerdo de Nivel de Servicio (SLA) de conectividad de máquina virtual de al menos el
99,9 %.
Una máquina virtual de instancia única con un SSD estándar tendrá un SLA de al menos el 99,5
%, mientras que una máquina virtual de instancia única con un HDD estándar tendrá un SLA de
al menos el 95 %. (

Respuesta 4: Es un rack pero de manera lógica.
Respuesta 5: NO, no es un conjunto de cosas similares, es una disposición lógica de máquinas
virtuales para lograr alta disponibilidad.
Espero que ayude.
