Why Software Developers Should Learn Docker?

With the big lot of technologies that developers can use, the software development experts need to identify the ones that they want to use and learn how they work. A custom software developer in India who is knowledgeable and experienced in using Docker can make your web development project a breeze. In order to understand the DevOps ecosystem and software development, developers can consider learning Docker. There are many reasons that would compel a developer to learn this DevOps tool and they include:

Optimize Hardware Usage

Containerization, just like virtual machines changes how developers optimize hardware usage. Virtual machines present some limitations when it comes to usage of hardware. For example, if you are hosting two applications that use the same language but are in different versions, you can get a solution by seeking a hack to execute it from a single virtual machine, however, you won’t be able to create a new virtual machine to allow you host the second application. Virtual machines do have limits; however, use of Docker allows you to make easy deployment of multiple applications while at the same time using different versions of similar language with no need to create a new virtual machine.

Collaboration and Distribution

If you intend to share containers and images, Dockers allow such social features so that it makes it possible for any individual to make contributions to a public or even private image. Communities and individuals can share and collaborate images. Users, can as well make votes for the images. A software developers team needs to take advantage of the benefits offered by Docker in developing software and website or apps.

High Availability and Multi Tenancy

When you use the right tools within the software development ecosystem, you can be able to run numerous instances of same application within the same server using Docker than when going the mainstream way. For example, using a proxy or a service scheduling and discovery tool, you are able to create a second server or even more servers. You can also create load balance of the traffic between various cluster nodes in which your containers resident.

Build Once, Run Anywhere

Docker is utilized in production systems; however, it is a tool that dedicated software developer teams can use in running same applications in the laptop or server of the developer. Docker can move from the dev environment to quality testing to production without exhibit changes. If you want to be closer to production, you can consider Docker. It solves the problem that many people experience, “It doesn’t work on my machine!” A majority of problems witnessed in software developments as well as operations are as a result of the differences occurring between production and development environments. Docker strives to eliminate this problem by ensuring that it can run everywhere.

Docker containers account for actual running of applications and they include user-files, operating system, and metadata. There are three things that containers come out with namely: Copy on Write, Namespaces, and Control Group. With Docker, you will find that all the configurations and dependencies are almost the same regardless of where you are running the application – be it on local machine, staging, or cloud server. The dependencies and configurations are same almost anywhere agile development pipeline is built that ships software from the dev environment through continuous integration to staging and production within the cloud server.

Easy Deployment of Applications

If you have tried deploying a software application having a big number of dependencies, it is likely that you experienced a very painful process. When on a system based on Linux, there are lots of apt-get installs involved for different software projects to enable run the code. However, with Docker, you have the dependencies built within the image itself. What this means is that whenever you need to carry out deployment of your application that is built into a Docker image, then all that is required is to have only the Docker and the image installed on the systems. This helps speed up the process of deployment on a novel machine. It also makes things simple. Using tools like Docker compose that is linked to a Docker registry makes it easy for you to deploy a system using only a few commands.

Accelerate Developers

The first thing in information technology is the development environment. Whatever you want from your dev environment - whether databases, different tools, networks, or instances, you can be able to create them using Docker with just simple commands.

Isolation and Dependency Misery

Using Docker allows developers to simplify the systems packages management while at the same time eliminating the problem of dependency through the isolation feature. Dockerizing an application could also mean isolating it into independent environments. When you have two applications dockerized, it means that you don’t need install nothing on the host machine, all you need is installing Docker and you will have every version running within an isolated environment.

Use with Multiple External Tools

It is possible to use Docker with several external tools such as orchestration tools, filesystem types, file storage technologies, monitoring tools, and logging software product or configuration management tools. This way, the developers don’t have to be stranded by not having the ability to use the DevOps tool with external tools in a software development environment.

These are some of the reasons developers would want to use Docker. It is still a viable solution for software development and enhances efficiency, minimizes dependencies, allows compatibility with external tools, and promotes easy deployment of software products or applications. You can hire software developer in India knowledgably in Docker to help with all your website development needs.
