Azure is a Microsoft-run cloud computing service powered by a global network of data centers. It provides a comprehensive suite of tools developers can use to build, deploy, and manage web applications.
Microsoft encourages developers to use Azure by offering support for multiple programming languages, tools, and frameworks. People around the globe can access the service to run their own Linux, Windows, and iOS applications.
The service offers useful solutions to businesses of any size. For instance, Azure can handle issues such as scaling, data security, legal compliance, and network security. Read on to learn more about the various use cases of Azure and how it works.
What Can You Do With Azure?
Azure opens the door for developers to run reliable and scalable web services. As a global service, you will be able to reach users around the globe while maintaining low-latency connections.
Here are just some of the popular use cases:
- Web Applications: Build, host, and scale web apps using Azure’s platform-as-a-service (PaaS) offering, Azure App Service. This cloud service provides features like automatic scaling, continuous deployment, and integration with many third-party development tools and services. Additionally, Azure offers form optimization tools to help developers streamline their web applications and improve user experience.
- Mobile Apps: Build, deploy, and manage mobile apps, including back-end services such as authentication, push notifications, and data storage.
- Containers: Use Azure’s machine virtualization services to deploy and manage Docker containers, making it easier to manage the lifecycle of your applications.
- Databases: Host and manage a wide range of databases, including relational databases, NoSQL databases, and big data solutions like Azure Cosmos DB. This allows you to run programs that gather data from multiple sources, such as an Inventory Planner app.
- Web Analytics: Analyze large databases with services like Azure Stream Analytics, Azure HDInsight, and Azure Machine Learning.
- Artificial Intelligence: Access support for AI applications using tools like Azure Cognitive Services and Azure Machine Learning.
As you can see, Azure is a comprehensive cloud computing solution, operating as Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).
How Azure Works: Datacenters, Regions, and Availability Zones
Azure Datacenters
Azure runs on physical infrastructure-the lowest common denominator we are concerned with here is the Azure data center.
According to Microsoft, there are over 200 of these data centers, each with power, cooling, and networking capabilities. To provide a reliable and universal service, these data centers are globally dispersed and are generally constructed in locations with a low risk of natural disasters.
Regions
Every Azure datacenter is assigned to a region, such as ‘Central US’ or ‘EU West’. There are a 60 Azure regions worldwide, each corresponding to a geographic area.
Azure regions contain at least one, but typically more, Azure data centers. Where there are multiple data centers in the same region, they are connected with high throughput Internet connections (with a latency of <2 milliseconds).
An Azure region is the location that you deploy your app to, so picking the correct one is an important task. However, Azure also operates ‘Availability Zones’ to help maintain low-latency connections within regions.
Availability Zones
Once you’ve selected your region, you might assume that your services are hosted on any data center in that grouping. In fact, with Microsoft Azure, you can choose which data centers to use as a priority. This works on an ‘Availability Zone’ model in which each data center is assigned a unique number within their region.
The benefits of the ‘Availability Zone’ structure are that it makes services more fault tolerant, accessible, and scalable than traditional data centers. This is largely thanks to the ultra-fast facilitation of data that Azure data centers have in their regional groupings. This is useful for two main purposes:
- Zonal services: You can select which availability zones will host your applications in various geographical zones. You can also choose backup data centers to take over the operation if the connection fails (e.g., due to malfunction or natural disaster).
- Zone-redundant services: You can select multiple availability zones for data storage, mitigating the risk of data loss.
How to Pick the Correct Azure Region
There are several considerations when picking the Azure region that will host your applications.
Firstly, there are some restrictions as Azure services are not yet available in every region. As such, double-check that your chosen region supports the services you need to build and manage your app.
The next consideration is latency. Using a tool like Azure Speed Test 2.0, you can easily see which Azure regions are ‘closest’ to you in terms of latency. In other words, with the best connection to your home or business network. If you are running personal or local services on Azure, you should pick the service with the lowest latency.
Finally, if you are running a worldwide service, you will need to consider the regions closest to your clients. This is especially important for larger businesses with customers worldwide that host multiple regional domains. This model can be tricky to configure correctly. For example, services that run on your Saudi domains should probably be hosted on the ‘Qatar’ or ‘UAE’ Azure regions to ensure rapid connection and reliability.
Conclusion
Microsoft Azure is a valuable tool in a developer’s arsenal. When configured correctly, you can build, deploy, and manage apps globally while guaranteeing low latency and accessibility for your users.
To use it most effectively, you should carefully consider which Azure region to deploy your apps onto, employ the best security practices, and make use of Availability Zone features to ensure reliable connectivity.
