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:
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.
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.
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.
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.
