The two most liked tools for creating and delivering cloud-based apps are Docker and Azure. We will look at running Docker on Azure in this article to get the best cloud computing performance.
We'll go through concerns, including setting up a Docker environment on Azure, improving performance, and fixing typical problems.
This article will provide you with helpful tips on how to utilize Docker and Azure together to produce high-performing cloud-based apps, whether you're a developer, administrator, or architect.
What Is Docker in Microsoft Azure?
Docker in Microsoft Azure refers to the Docker platform’s integration with the Azure cloud computing service. It is a platform for developers that allows them to package, distribute, and operate applications in containers.
Containers are small, portable, and self-contained, making them perfect for cloud-based systems. Developers may utilize Docker to construct and manage containerized apps, then deploy and execute them on Azure by merging these two technologies.
What Are the Main Uses of Docker in Azure?
Below are the main uses of Docker in Azure:
Application Development and Deployment
Docker enables developers to construct and test apps in a standardized environment before deploying them as containers to Azure. This simplifies the development, testing, and deployment of cloud applications.
Microservices-based applications may be deployed on Azure using Docker. This enables developers to deconstruct big apps into smaller, more manageable components that can be created and deployed independently.
Scaling and Load Balancing
Docker on Azure enables simple application scaling by spinning up extra containers as needed.
Load balancing features are also provided by Azure, which may be utilized to divide incoming traffic over numerous containers.
Continuous Integration and Delivery (CI/CD)
Docker may be connected with Azure DevOps, allowing for continuous application integration and delivery. This contributes to a shorter time to market for new features and upgrades.
By utilizing Azure's auto-scaling capability and pay-as-you-go approach, expenses may be reduced because resources will be utilized based on demand.
How to Create and Deploy a Docker Container in Azure?
The general process to develop and deploy a Docker container in Azure is outlined below:
Create a fresh instance of the Azure Container Registry (ACR): Here, you may manage and save your Docker images in a secure registry. Through the Azure Portal, Azure CLI, or Azure PowerShell, a new ACR instance can be created.
Create a Docker image of your application: You can create an image of your application using a Docker file. This can be done in a build environment or on your personal computer for local development.
Push the Docker image to the ACR: Once the image has been built, use the docker push command to send it to your ACR instance.
Create a fresh Azure Container Instance (ACI): You can launch a fresh ACI using the Azure CLI or Azure Portal. You can select setup settings, including the amount of memory, CPU cores, and exposed ports.
Start the container: You may launch the ACI using the Azure CLI, Azure Portal, or Azure REST API after it has been created.
Manage the container: You may use Azure Container Instances to manage your container, such as scaling or terminating it, and Azure Monitor to monitor the performance and resource utilization.
Azure Containers vs. Docker: What's the Difference?
Both Azure Containers and Docker are containerization technologies, although they have certain major differences:
Which One Is Best To Choose for Application Development?
Whether to use Docker or Azure Containers for application development is determined by the project's individual requirements and limits. Both technologies have advantages and disadvantages.

What Are the Pros and Cons of Using Docker in Azure?
If you plan to use Docker in Azure, below are some pros and cons that you should be aware of:
Containerized apps may be created and deployed using the robust technologies of Docker and Azure.
While Azure offers a variety of services and tools for running and managing containers in the cloud, Docker offers a consistent, portable environment for developing and operating applications.
Docker can be connected with Azure DevOps for continuous integration and delivery (CI/CD) of apps, although it is not a component of Azure DevOps.
No, Docker is not owned by Microsoft.
Only if you like awesome pages that are rapidly customizable to your needs.
Virtual machines (VMs) and Docker both have their own advantages and use cases.
While Docker delivers lightweight, portable, and self-sufficient containers, VMs offer full-featured operating systems.
Docker is better suited for apps that use microservices since it uses resources more effectively.
Create an Azure Container Registry (ACR) instance to store and manage the Docker image before launching an Azure Container Instance (ACI) to execute the container on Azure.
The az container command allows you to build, manage, and keep an eye on Azure Container Instances while running Docker in Azure CLI.
The industry continues to utilize Docker extensively, and it has a sizable and vibrant community. While competing container orchestration systems like Kubernetes compete with it, it is not going out of style.
However, for creating and deploying containerized apps, Docker continues to be a popular option.
