These packages are also known as container images which acts as an unit for distributing of software applications. On the other hand Software containerization is an Operating System virtualization method that is used to deploy and run containers without using a virtual machine (VM). </p> <h2> All about Docker ? </h2> <p>Docker is a containerization platform used to develop, ship, and run containers.One can run Docker on using a desktop or laptop to test and develop software applications using Linux, Windows, and mac Operating Systems. Many clouds, including Azure,AWS,GCP, support Docker.The Docker platform consists of several components that we use to build, run, and manage our containerized applications</p> <h2> Docker Engine </h2> <p>The Docker Engine having several components configured as client-server implementation where the client and server run simultaneously on the same host. The client communicates with the server using a REST API, which enables the client to also communicate with a remote server instance.</p> <h2> The Docker Client </h2> <p>The Docker client is none other than a command-line application that provides us with a command line interface (CLI) to interact with a Docker server. The docker command uses the Docker REST API to send instructions to either a local or remote server and functions as the primary interface we use to manage the containers that are created</p> <h2> The Docker Server </h2> <p>The Docker server is a daemon named dockerd. The dockerd daemon responds to requests from the client via the Docker REST API and can interact with other daemons. The Docker server is also responsible for tracking the lifecycle of our containers providing us all the necessary info for our applications</p> <h2> Docker objects </h2> <p>There are several objects that we create and configure to support the container deployments which includes networks, storage volumes, plugins, and other service objects. We won't cover all of these objects here, but it's good to keep in mind that these objects are items that we can create and deploy as needed.</p> <h2> Docker Hub </h2> <p>Docker Hub is a Software as a Service (SaaS) Docker container registry. Docker registries are repositories that we use to store and distribute the container images we create. Docker Hub is the default public registry Docker uses for image management.</p> <h2> Conclusion </h2> <p>This was all about Docker &amp; its Services.

Also, this article is beginner-friendly so anyone having a basic idea of cloud computing and its service models can go for it. </p> <h2> Azure Virtual machines </h2> <p>Virtual machines are nothing but software that gives us access to a remote physical computer, which means you get a processor, memory, and storage in virtual mode. Just like physical computers you can install OS and run software in the cloud using a virtual machine. </p> <h3> When to use Virtual Machines(V M) </h3> <p>One can use VMs during testing and development, running <br> application on the cloud, extending the data center over the cloud ,etc. </p> <h2> Azure Virtual Destops (AVD) </h2> <p>This is an application virtualization service designed for enabling users to use a cloud-hosted version of Windows from any location. Like accessing a Windows machine and accessing remote Windows apps from anywhere just using the Internet. This runs over Windows, Mac, Linux ,android and also Ios. This service is used for enhancing security and providing better user experiences </p> <h2> Azure APP Service </h2> <p>This service is designed to quickly build, scale &amp; deploy, web, mobile apps, and APIs in the easiest way. APP service is having the features like hosting web Apps and API, <br> storing mobile app data in cloud databases, Authentication and push notifications, and enabling custom back end logic using<br> Nodejs or C#.</p> <h2> Azure Container Instances (ACI) or Azure Kubernetes Service (AKS) </h2> <p>These services are designed to deploy and manage containers. Containers are lightweight visualization environments this service is just like running multiple VMs in a single Host machine, Which reduces cost and increases scalability. <br> On the other hand, Kubernetes is an open-source container orchestration software system designed to automate deployment, management, and scalability, and the same services are provided by AKS </p> <h2> Azure Functions </h2> <p>This type of service is designed for code deployment and execution without any need for server infrastructure, web server, or any configurations . Azure Functions can be implemented in Languages like C#, Node Js, python Etc. Also, this reduces cost and is mostly used in IoT and event driven apps </p> <h2> Azure Logic Apps </h2> <p>This service is similar to Azure functions enabling developers to trigger logic based on an event But the difference is that Logic apps are used to automate workflows to automate business scenarios </p> <h2> Conclusion </h2> <p>This was all about Azure Compute Services.
