DevOps - Overview
2
Introduction
  • DevOps is a term emerged from the combination of
    Development and Operations. The role of a DevOps
    engineer is to automate all the operational work
    in the way that a developer would do. The idea is
    to encourage frequent releases to increase
    quality and get early feedback.
  • Hence, according to me, the main two objectives
    of DevOps are increasing the speed and quality
    the deliveries.

3
Characteristics of DevOps
  • Ability to write code beyond simple scripts.
  • Focus on stability and uptime.
  • Extra focus on moving between states -
  • In dev land, I have situations when the end
    result of a particular feature was analysed on
    its ow merit, without taking into consideration
    how a system can be moved from its desired future
    state. DevOps pays extra attention to this
    problematic area.

4
How DevOps works?
  • DevOps integrating targets item conveyance,
    consistent testing, quality testing, feature
    advancement, and upkeep discharges so as to
    enhance dependability and security and give
    quicker improvement and arrangement cycles.

5
What are the DevOps tools?
  • Nagios (and Icinga)
  • Monit
  • ELK Elasticsearch, Logstash, Kibana by means
    of Logz.io.
  • io
  • Jenkins
  • Docker
  • Ansible
  • Collectl
  • Git (GitHub)

6
Advantages
  • There are several clear advantages to be had from
    DevOps. Collaboration can help alleviate
    deep-rooted problems such as the industry
    acceptance that projects will tend to run late,
    won't work properly or will cost more than
    anticipated. Prior to DevOps as a solution, this
    would mean that many projects would go back to
    square one. With DevOps, a solution is suggested
    early on which means those problems are handled
    and worked through, saving time and money.
  • Also, if any issues arise, they can be dealt with
    by team members who can take ownership and solve
    the problem.

7
Why DevOps is so important?
  • Shorter Advancement Cycles, Quicker Development
  • Decreased Organization flaws, Rollbacks, and Time
    to Recuperate
  • Enhanced Correspondence and Coordinated effort
  • Expanded Efficiencies
  • Decreased Expenses and IT Headcount

8
Disadvantages
  • Once you're invested in the idea of DevOps
    there's a temptation to take it a step further
    and abandon the idea of specialists altogether
    and encourage your developers to develop skills
    in multitasking as QAs, system administrators and
    release managers etc.
  • DevOps is also naturally suited to a development
    team that is already agile, i.e. fast iteration
    cycles, flexible scope model and dedicated long
    term resource allocation etc. If your team
    currently works in something such as a fixed
    scope model, then introducing DevOps will need
    wider business support to change the way the team
    works, otherwise it will feel like progress has
    slowed and functional targets are no longer being
    met.

DevOps Technical Challenges
  • Environment provisioning
  • Manual testing
  • No DevOps center of excellence
  • Test data
  • Manual deployments
  • Planning in a DevOps environment
  • DevOps and suppliers
  • DevOps and governance
  • No integrated tools architecture
  • Manual releases

10
Conclusion
  • Very few companies reach the hyper-growth stage
    at which point this post is directly applicable.
    For many companies, a pure DevOps model built on
    modern cloud native primitives may be entirely
    sufficient given the number of engineers
    involved, the system reliability required, and
    the product iteration rate the business requires.
