How docker helps developers to develop application fast and makes developers life easy

[vc_row][vc_column][vc_column_text]Docker has changed the life of developers owing it ease of use features. Docker uses a virtual machine that makes it workable so enable to handle more workloads. Now deployment, testing, staging, and production have become easy process owing coming up of Dockers. First we shall let we know what basically is Docker and then we would know how it is changing the life of developers as well as the field of developing.

About Docker

It is an open source platform for running, developing and shipping the applications. Its main task is to provide the applications in a faster way. With the help of docker, you may separate the applications from the infrastructure and may treat the infrastructure like a managed application. It assists you to test faster, ship code faster, shorten the cycle and deploy faster between the running code and writing code.

Docker does all kind of things with the help of a lightweight container virtualization platform along tools as well as workflows that assist you to deploy and manage the applications. It offers a way to run any kind of applications which is isolated in a container. The security and isolation permit to run several containers simultaneously on the host.[/vc_column_text][mk_custom_list]

  • May get the application in docker containers.
  • Shipping and distributing the containers to teams for testing and development.
  • Implement the application to production management.

How is it effective?

Faster Delivery

One best thing is that they assist you along the development cycle. It allows the developers to create on local containers that contain the services and applications which can be further integrated into a deployment workflow as well as a continuous integration.

Scaling and deploying more easily

Owing container based, it allow for very portable workloads. The docker container can be run on the cloud, physical or virtual machines as well as on local host. Owing lightweight and portability, it makes the dynamically managing workloads easy. With the help of docker, you may easily tear down or scale up the serve ices as well as applications. Scaling is done in real time environment.

Useful high-density environment

Docker is fast and lightweight. It offers a cost-effective and viable alternative to hyper based virtual machines. They are basically useful in the high-density environment.

Major Components of Docker

Docker

It is an open source container which utilizes virtualization platform.
Docker Hub – It uses the software as a service platform for managing and sharing the docker containers.

Why Dicker?

Unlike window based applications, the web-based software run on the server. For a site, the classic management embraces building 3-4 distinct layers such as staging, production, development, and testing. Along with the set of rules, the strategy incorporates, at least, one server per layer. The build may be deployed to next level server when the software was ready for next promotion.

But now virtual machines have now changed everything and it allows you to create several servers for use. Owing this each module is tested separately which is merged further into mainline for final testing without investing too much for new hardware. For having virtual machines has also solved the issue of debugging as now they can be easily done.

The main issue with the virtual machine is speed and size. Each virtual machine acts as an operating system which means that we allocate some space and so we can install the build on that OS. Now docker has now solved the issue as on one operating we may run to or more virtual machines which provides the capability to run much application even if you have low space on your computer.

A docker runs in the kernel instead of running in the application space. Moreover, it makes itself as a part of the operating system. Docker limits to the modern kernel of Linux both container or host machine but it also simplifies the switching process of OS.

Docker has now solved many issues such as making copies, debugging, testing, deployment and many more. Owing its fast speed it has now changed the method of doing work of developers.

Docker in Production

Docker on a couple cloud servers as well as on your local machine is one thing but making it production ready is a totally distinct thing. In early days when it came to production, the dockers were like Wild West. The container orchestration is the most common thrown around phrase which is the practice of taking dockerized services and apps which are scheduled onto clusters of resources. The organization does not know where the containers are running and it is like that they are serving or running the right request whether it is of internal services, web traffic or queues of messaging.

Nowadays the big player in the orchestra is Docker swarm, AWS EC2 container service etc. This orchestra may manage the containers in a well way but along this, it also comes with container healing, red or blue whistles, load balancing, inter-container networking and service discovery. There are other challenges such as configuring or logging when you account for docker production.[/vc_column_text][/vc_column][/vc_row]
