What Exact DevOps is?

-
                     Hello People, Present days DevOps has become one of most wanted thing for job seekers and as well as Organizations, but when you search for what is DevOps on internet, different websites are giving different definitions which causing confusion. In this post, I am giving some basic overview of what DevOps is exactly.



Pre-Requisites:

  1. Linux
  2. Scripting
  3. Virtualization 
  4. Networking
  5. Coding ( coding is not mandatory if you know, it's added advantage)

Certification Procedure:

  Present Days Certification is becoming more important for everyone, and so many people asking is there any certification for DevOps. First, we need to remember one thing there is no organization behind DevOps it's completely community-based. And there is no authorized certification for DevOps.
If someone says we will provide certification for DevOps they will provide course completion certification only. But there are so many tools for DevOps in the market, you can pick some trending tools and you can go for certification for that tools like Docker, Ansible, Puppet, etc.,

What exactly DevOps is?

From all definitions those are available on the internet we can say devops is an s/w approach or we can say it's a culture. DevOps is not a tool or product it's an s/w approach, by using this we are implementing a common environment for all teams in an organization. which will help organizations to deliver their things with high frequency and helps to deliver quality o/p.

Why DevOps? 

Why we need to implement this DevOps Environment for our projects?
There are Four major Goals to implement devops.
  • Communication
  • Collaboration
  • Integration
  • Automation
Communication & Collaboration :
                 Let's say ram and Sam are working in an organization for the same project, ram is from the development team and sam is from build & release team. One day ram completed his development and he forwarded his code to build team. sam started his build procedure, and he is facing some errors with that code and he sent an email to ram to check his code. but ram is saying his code is fine, and they started blaming each other which is not good for the organization, why because this situation is between two teams not between two persons, it will eat time and it may spoil healthy environment in the organization.
                 By using DevOps functionalities we can make a history of each and every action which is happening in the development phase.
For Example
  • Who is doing changes
  • what changes happening to the source code
  • when she/he doing changes
  • where exactly they changed 
So using this history we can provide better communication between teams, and we can avoid frictions between teams, that will help the organization to work faster manner.
Integration and Automation :
                 if you observe 1990's or early of the 2000s if we want to use any application or software, we need to go to the market and by CD's and DVD's those are called as COTS applications.
But present days every organization placing their applications on the internet, and from we are downloading and we are using. in this modern era, every organization is trying to deliver their thing with high frequency that's why some organizations are dealing with daily deployments and some organizations are dealing with hourly deployments. if we want to work with this speed we need to involve automation for our projects, DevOps will help you to integrate each and every phase in SDLC procedure, and we can trigger automation, which will help you to work faster.

Who can Learn DevOps?

Anyone can learn DevOps all you need is knowledge about IT firm.

Docker Basic Terminologies

Image
Before going deeply into Docker first we need to know about some basic terminologies which we use in dockers frequently. Docker Overview : Docker is a container management tool, by using docker we can wrap/compress huge environments into small docker images, not only environment we can wrap source-codes, applications, environments into docker images. Docker is a lite weight tool which is worked based on os-level virtualization which is known as containerization. Docker Terminologies: Docker CLI: This is the utility we use when we run any docker commands e.g. docker run (docker container run), ' docker images' , ' docker ps' etc. It allows us to run these commands which a human can easily understand. Docker Engine/ Demon: This is the part which does rest of the magic and knows how to talk to the kernel, makes the system calls to create, operate and manage containers, which we as users of Docker don’t have to worry about. Docker machine: Docker Machin...
