Docker Course And Certification

What is Docker?

Docker is an open platform that offers platform-as-a-service (PaaS) product which uses OS-level virtualization to deliver software in different packages known as the containers. 

The Containers are kept away from one another and bundle their own software, configuration files and libraries; they have the abilty to communicate with each other through well-defined channels.  

A man called Solomon Hykes helped found Docker, which makes containers easy to use. And when the release of Docker 1.0 in June 2014 was processed, the buzz became a load roar. And since then and over the years, it has only got louder.

Companies are now getting acquainted and are adopting Docker at a remarkable rate. Countless and numerous businesses that have already moved their server applications from virtual machines (VM) to containers and more are still moving.

Today, Docker, and its open source founder named Moby, is bigger than you can imagine. With Docker records  3.5 million applications have been placed in different containers using the Docker technology and over 37 billion applicatons that have been containerized and also have been downloaded.

The Real world data have backed up their conclusion that Docker is widely adopted all over the world. This DataDog, a cloud-monitoring system, found that by the month of March 2016, "And 13.6 percent of Datadog's customers had adopted Docker since then.

One year later the number gotten in 2016 has grown to 18.8 percent. That's almost an amazing 40 percent market share growth just in about 12 months." RightScale also did observed in its RightScale 2018 State of the Cloud report; that Docker's adoption by the industry has gain more increase to 49 percent just from 35 percent in 2017.

Features Of Docker

1. Easy and Faster Configuration

2. Increase productivity

3. Application Isolation

4. Swarm

5. Routing Mesh

6. Services

7. Security Management

1.  Easy and Faster Configuration: This is a very key feature of docker it helps us in configuring the system very easily and faster. Also We can deploy our code in no less time and effortlessly. 

2. Increase In Productivity: It helps in easing technical configuration and rapid deployment of applications. No doubt it is the reason why it has increase productivity. Docker not only have the capability to help in executing the application in isolated environment but also it has also reduced the resources.

3. Application Isolation: It is also enabled to provide containers that are used to run applications in an isolation environment. 

4. Swarm: It is a clustering and it is also a scheduling tool for Docker containers. Swarm makes good use of the Docker API as its front end, which helps users to use various tools in control it.

5. Routing Mesh: It helps to route the incoming requests for published ports on the available nodes to an active container. 

6. Services: It is a list of tasks that allows us to specify the state of the container that is inside a cluster. 

7. Security: This allows us to be able to save secrets into the swarm itself and then we can choose to give services or clients access to certain secrets.

Benefits Of Docker

Some of the benefits include: 

1. Docker Containers gives agility

2. Consistent and Isolated Environment. 

3. Cost-effectiveness with Fast Deployment. 

4. Mobility – Ability to Run Anywhere. 

5. Repeatability and Automation. 

6. Test, Roll Back and Deploy. 

7. Flexibility. 

Why Study Docker: 

Reasons to learn docker: 

1. Docker is time saving, easy to learn and effortless to integrate.

2. Dockerized apps don’t require their own operating system.

3. Each Dockerized app gets its own set of dependencies. 

4. Most of the heavy lifting is already done.

5. Controlling Docker containers can be fully automated.

6. Job opportunities and career advancement.

7. Increase your earning potential
