    Day-1 DevOps Introduction

    What is Devops
    DevOps is a set of practices that combines software development (Dev) and IT operations
    (Ops). It aims to shorten the systems development life cycle and provide continuous delivery
    with high software quality.

    Devops is not a process it's a prectice to achive and provide faster delivery.

    DevOps describes a culture and set of processes that bring development and operations teams
    together to complete software development. It allows organizations to create and improve
    products at a faster pace than they can with traditional software development approaches. And,
    it’s gaining popularity at a rapid rate.

    Dev vs DevOps
    Why we use Devops

     Quicker Deployment Cycles.


     Increse in product quality.
     Faster Innovation Cycles
     Cost reduction.
    Basic requirement as a DevOps

     Programming Concept : Need knowledge for torbleshooting of issue .


     Networking : Network protocols and DNS for connectivity and all software
    related part of network.
     Server Administration : all server related knowlege of all type of server windows
    and linux like user creation, users and groups, Os installations, Create Partition,
    Expert in server managment.
     Web Server : knowledge of all application servers.

    What does a devOps engineer do


    DevOps is a series of practices and processes that are intended to speed up and
    automate aspects of the processes of developing, testing and releasing software,
    allowing for the continuous delivery of software and software updates. Whereas
    previously software would be developed by developers and then passed onto testers to
    test and go back and forth between them, devOps practices aim to simplify this by
    integrating these previously separate teams. DevOps engineers are responsible for
    facilitating this.

    The role of a devOps engineer combines aspects of a technical role and an IT operations
    role. While engineers are likely to be involved with coding, and a knowledge of coding
    languages and principles is required to find problems and build solutions, this is not the
    primary role of a devOps engineer. More senior engineers are likely to be more involved
    in the project management and planning side of development.
    Roles and responsibilities for devOps engineers
    Typical responsibilities for devOps engineers include:

    • building and setting up new development tools and infrastructure

    • understanding the needs of stakeholders and conveying this to developers

    • working on ways to automate and improve development and release processes

    • testing and examining code written by others and analysing results.

    • ensuring that systems are safe and secure against cybersecurity threats

    • identifying technical problems and developing software updates and ‘fixes’

    • working with software developers and software engineers to ensure that


    development follows established processes and works as intended.

    • planning out projects and being involved in project management decisions.

    Common DevOps Roles and


    Responsibilities
    Now that we’ve looked at many of the common principles of DevOps, we can start to see how
    they manifest themselves in DevOps roles and responsibilities. Let’s go through a number of
    common DevOps duties and break down how these processes benefit engineering and IT
    teams.
    Application and Infrastructure Planning, Testing and
    Development
    The entire DevOps team is in charge of application and infrastructure planning, testing and
    development. Sharing the responsibility for the development and release pipeline leads to more
    reliable services.

    Maintaining CI/CD Pipelines


    Being part of a DevOps team means we have a responsibility for building a CI/CD pipeline and
    optimizing processes.

    Automation Implementation
    automation is a core principle of DevOps. It’s the responsibility of devops to automate routine
    manual task or automate the process.

    On-Call, Incident Response and Incident


    Management
    As a devops prospective our responsibility to provide 24*7 service during any production issue
    or major releases. and immediate response to any production issue.

    Monitoring
    DevOps teams are responsible for the implementation of actionable monitoring solutions. The
    organization needs to collect data and know how they can take action with it. The DevOps team
    is responsible for provide data like server utilization, major logs and server monitoring.
    Monitoring is just one small step into building highly observable systems – but it’s an important
    start for building reliable systems.

    Provide RCA
    DevOps teams are responsible for provide production issue RCA and provide reason for issue
    occur on production server.
    DevOps lifecycle: -

    Plan
    Monitor Code

    Operate Build

    Deploy Test
    Integrate

    The cycle is divided into 5 stages: -


    DevOps Lifecycle
    1. Continuous Development: - This stage involves committing
    code to version control tools such as Git, BitBucket etc for maintaining the different
    versions of the code, the tools like Ant, Maven, Gradle for building/packaging the code into
    an executable file that can be forwarded to the QA’s for testing.
    2. Continuous Integrating: - The stage is critical point in the whole DevOps
    lifecycle. It deals with integrating the different stages of the DevOps lifecycle, and is
    therefore plays an important role in automating the whole DevOps process.
    3. Continuous Deployment: - In this stage, the code is build, after
    build is successful, then the output files in form of war in java or .dlls in .Net are then
    deployed on the respective servers on the the application is hosted or on which you want to
    host new application.
    4. Continuous Testing: - The stage deals with automated testing of the application
    pushed by the developer. If there is an error, the message is sent back to the integration
    tool, this tool in turn notifies the developer of the error. If the test was a success, the
    message is sent to integration tool which pushes the build on the server.
    5. Continuous Monitoring: - The stage continuously monitors the deployed
    application for bugs or crashes. It can be setup to collect user feedback. The collected data
    is then sent to the developers to improve the application.
