A Brief on Why to use Docker Online Training



Dockers have gained a lot of popularity nowadays in the Information technology field as it is being adopted at a fast rate in the production environment. Dockers emerged after containerization was introduced in the application production picture. Before containerization Virtualization was prevalent to isolate and organize applications, but it was a bulky method. 

Docker is a platform that helps a developer to pack an application along with its dependencies in one container to make sure the application works in any environment. 

 

REASONS TO USE DOCKER CONTAINERIZATION

Using Docker Containerization has many benefits over other methods, such as the ones mentioned below.

  1. Since containers have no guest Operation Systems of their own, they can share required libraries and resources whenever needed using the host’s operating system.
  2. Containers are light in weight as compared to virtual machines and thus make booting a container very quick.
  3. It makes processing applications faster by running the container application-specific binaries and libraries on the host kernel.

 

WHAT IS DOCKER?

Docker is an open-source online project platform that makes containers and container-based applications easier. Earlier it only ran on Linux, but nowadays it has been updated to run on macOS as well as Windows. Dockers gave the idea that a process can be run in isolation from the rest of the operating environment without being affected by other parallel processes. Docker has made containers more portable and flexible than it was earlier.

 

ADVANTAGES OF DOCKER

Docker container that runs on docker engines has several advantages over others such as:

  1. Docker has an industry standard and thus can be ported anywhere without facing any issues.
  2. Docker containers are lightweight and do not require a specific operating system for each application. They provide higher server efficiencies and also reduce the costs used for servers and licensing. 
  3. Since Dockers provide the strongest default isolation in the application industry, applications are much safer in containers.

 
DOCKER VS KUBERNETES

Dockers vs Kubernetes can be confused with one another at times, but one of the basic differences is that Kubernetes run across a cluster whereas dockers run on a single node. Kubernetes can coordinate clusters of nodes together in production in an efficient manner and this is more extensive than Docker. Both when worked together can provide amazing benefits when developing applications.

 

PREREQUISITES FOR DOCKER ONLINE TRAINING

Even though almost anyone interested in developing applications, can earn docker there are some basic prerequisites for learning docker

  1. For a developer who is already developing applications and knows how to build and run an application, it is very easy to learn docker. This includes the basic experience of creating applications using any of the following technologies.

a.     .NET Core

b.     Java

c.     Node.JS

d.     PHP

e.     Python

  1. For others, all one needs is the basic knowledge of computer science:
  2. Basic knowledge of Bash and its working, that is how to handle various files and folders.
  3. Basic knowledge of networking on required Operating Systems such as Linux/Ubuntu or Windows.
  4. Apt-get basics about installing packages
  5. The basic working of the operating system

 

FUTURE SCOPES FOR DOCKER

Two-thirds of all IT companies in the containerized industry are already using it, with the docker adoption rate being more than 40 percent. The average number of running containers these companies have in production quintuple this number within 10 months of usage. The frameworks used in docker container production are PHP, Java, Node, and Ruby making it easier to adopt, and many large companies such as Paypal, SPotify, and ING are using docker. 

Docker can facilitate savings by reducing the requirement of infrastructure resources and this has a high return on investment. It also provides a rapid and continuous development on multi-cloud platforms
