Why Azure work
Azure is a huge collection of servers and networking hardware, which runs a complex set of
distributed applications. These applications orchestrate the configuration and operation of
virtualized hardware and software on those servers. The orchestration of these servers is what
makes Azure so powerful.
Why do people trust their workloads to Microsoft Azure?
It’s been said that the on-premise data center has no future. Like mainframes and dial-up modems
before them, self-hosted data centers are becoming obsolete, being replaced by increasingly
available and affordable cloud solutions. Several important players have emerged in the cloud
service sphere, including Amazon Web Services (AWS), perennial computing giant IBM, and Apple’s
ubiquitous iCloud, which holds the picture memories and song preferences of hundreds of millions
of smartphone users, among other data. With so many options, why are companies like 3M, BMW, and
GE moving workloads to Microsoft Azure? Just some of the reasons:
Flexibility
With Microsoft Azure you can spin up new services and geometrically scale your data storage
capabilities on the fly. Compare this to a static data center, which would require new hardware
and OS purchasing, provisioning, and deployment before additional power could be brought to bear
against your IT challenges. This modern flexibility makes Azure a tempting solution for
organizations of any size.
Cost
Azure solutions don’t just make it faster and easier to add and scale infrastructure, they make
it cheaper. Physical services and infrastructure devices like routers, load balancers and more
quickly add up to thousands or even hundreds of thousands of dollars. Then there’s the IT
expertise required to run this equipment, which amounts to major payroll overhead. By leveraging
Microsoft’s massive infrastructure and expertise, Azure can trim our annual IT budget by
head-turning percentages.
Applications
With a la carte service offerings like Visual Studio Team Services, Visual Studio Application
Insights, and Azure’s scalable, on-demand storage for both frequently accessed and ‘cold’ data,
Microsoft makes developing and testing mission-critical integrations a snap. Move an application
from test to production mode on the fly across a globally distributed network. Microsoft also
offers substantial licensing discounts for migrating their existing integrations to Azure, which
represents even more opportunity for savings.
Disaster recovery
Sometimes the unthinkable becomes the very immediate reality. Another advantage of Microsoft
Azure lay in its high-speed and geographically decentralized infrastructure, which creates
limitless options for disaster recovery plans. Ensure that your critical application and data
can run from redundant sites during recovery periods that last minutes or hours instead of days.
Lost time is lost business, and with Azure you can guarantee continuous service delivery even
when disaster strikes.
How Azure works
It is essential to understand the internal workings of Azure so that we can design our
applications on Azure effectively with high availability, data residency, resilience, etc.
How Angular Works?
Microsoft Azure is completely based on the concept of virtualization. So, similar to other
virtualized data center, it also contains racks. Each rack has a separate power unit and network
switch, and also each rack is integrated with software called Fabric-Controller. This
Fabric-controller is a distributed application, which is responsible for managing and monitoring
servers within the rack. In case of any server failure, the Fabric-controller recognizes it and
recovers it. And Each of these Fabric-Controller is, in turn, connected to a piece of software
called Orchestrator. This Orchestrator includes web-services, Rest API to create, update, and
delete resources.
When a request is made by the user either using PowerShell or Azure portal. First, it will go to
the Orchestrator, where it will fundamentally do three things:
1. Authenticate the User
2. It will Authorize the user, i.e., it will check whether the user is allowed to do the
requested task.
3. It will look into the database for the availability of space based on the resources and pass
the request to an appropriate Azure Fabric controller to execute the request.
Combinations of racks form a cluster. We have multiple clusters within a data center, and we can
have multiple Data Centers within an Availability zone, multiple Availability zones within a
Region, and multiple Regions within Geography.
o Geographies: It is a discrete market, typically contains two or more regions that preserves
data residency and compliance boundaries.
o Azure regions: A region is a collection of data centers deployed within a defined perimeter
and interconnected through a dedicated regional low-latency network.
Azure covers more global regions than any other cloud provider, which offers the scalability
needed to bring applications and users closer around the world. It is globally available in 50
regions around the world. Due to its availability over many regions, it helps in preserving data
residency and offers comprehensive compliance and flexible options to the customers.
