Why Use DevOps?

Principal Consultant and DevOps specialist, Alan Fryer offers 5 reasons why organisations ought to be considering DevOps

Businesses are under more pressure to deliver IT systems faster in response to a number of factors which can be driven by legislation, reducing time to market to gain a competitive edge or improve process to reduce costs.  DevOps implemented correctly while adopting automation tools such as Chef, Puppet, Ansible and Salt can help a business to satisfy these goals.  DevOps promotes a culture of collaboration between the development and operational disciplines enabling each to understand one another’s concerns and provides the following benefits:
 

#1 Shorter Development Times

Automated provisioning allows developers to stand up a development environment themselves with all the right resources, cpu, memory, storage, network quickly.  This allows developers to be more creative and innovative, giving them more time to try multiple options, run different scenarios, and test code more thoroughly leading to improved quality.
 

#2 Increased Release Velocity

The shorter development times leads to an increase in the frequencies of software released into production allowing the organisations to react to change quickly maintaining a completive advantage.  DevOps enables organisations to move faster in the right direction, drives productivity across development and operations delivering better services, faster, at less cost.
 

#3 Improved Quality of Releases

The use of a common automation tool enables DevOps to create consistent environments across the development, test and production environments.  This improves the quality of the systems being released and reduces the time spent debugging problems caused by inconsistent configuration between these environments.  The entire team shares the responsibility and collaboration ensures that development and operations are involved in all the stages of the delivery cycle.  This ensures that development takes into account operational requirements with operations gaining a better understanding of the systems being delivered.  Problems are identified early on in the release cycle, and with improved defect detection, significantly reduces the number of pre and post deployment issues.  The whole team is accountable for building, deploying and running an application that works as expected and share and the same goals for quality, performance, user experience, stability and security.


#4 Production Issue Resolution Speed

Even if the likelihood of a failure is minimised, when failures occur, the time to fix is significantly reduced in a DevOps environment when compared to a traditional IT environment.  This can be attributed to the fact that the developers and operations are involved in all the stages of the release from design through to release, so understand each other’s concerns.  As there no boundaries, the team members with the right skills and knowledge of the system are at hand to work together to resolve issues quickly.
 

#5 Innovation

If DevOps is adopted correctly it can help an organisation to innovate and grow.  Product and service offerings can be introduced, tested, and rolled out much more quickly to the market place helping to gain a competitive advantage.  The principles of DevOps allow IT teams to produce and deliver value quickly, test out hypotheses with real users, and roll out services and products that bring in revenue to help grow the business and increase profit.
