Why Learn DevOps
DevOps is a set of practices or processes that combines software development and information technology operations. It is becoming popular because it enables businesses to achieve mainly two objectives; decrease systems development life cycle time and provide continuous product delivery with high quality. Increasing the pace of software delivery is not possible with traditional software development methodology as the methods are cumbersome and are conservative to adopt different sets of tools because of the siloed mentality of cross-functional teams. Moreover, DevOps requires teams to be highly collaborative and responsive. It requires teams to adopt toolchains that fit into the key aspects of development and delivery processes i.e. Coding, building, testing, packaging, releasing, configuring, monitoring.1,2 Moreover, DevOps is about the unification of Development and Operations through collaborative processes and heavy use of automation to deploy software faster.
Among the many reasons for learning or adopting DevOps as a culture3, these listed below highlight some of the biggest beneficial reasons to consider.
There are hard numbers now that suggest that companies that excel at DevOps are 11% more likely to see a double-digit annual growth rate.4 Improving user experience by pushing more releases into production enables organizations to sustain competitive advantage and maintain closeness to the consumer’s needs of their product. With this increased velocity there is a need for collaboration and minimum friction between teams that are responsible for software delivery.
Enhanced Team Utilization and Collaboration
Combining software development and IT operations makes development and operations teams adopt a set of tools that build on existing or new practices and principles. Some of the tools that are fit for these practices are Gradle, Git, Jenkins Bamboo, Ansible, Kubernetes, Docker, Puppet and Ansible. Development IDE’s can be integrated with these tools and also the deployment process can be kept as code along with the application’s source code. A general trend is to make custom scripts for deployment and move towards the project as code to achieve consistency and repeatability.5 This helps in making the teams more productive and it also keeps them happy as collaboration brings value by creating frequent and problem-free deployments.
Reduction of Problems in Production
As mentioned above, automation of DevOps is also possible by using an appropriate combination of automation tools suiting existing processes and eminent cultures to reduce human interference and errors in delivery pipelines. It results in the reduction of problems in production and fosters a culture of transparency with shared responsibility among teams and members of the organization.
It is very important to factor in people and their motivation while building software. DevOps takes care of it by encouraging the use of data provided by tools and users in real-time in order to maintain the quality. DevOps is heavily dependent on automation to make delivery over a period of a few hours. Automation in DevOps fosters speed, greater accuracy, consistency, and reliability.6 DevOps also involves an analysis of user behavior which results in the design of testing scenarios, allowing teams to meet user’s expectations in less time.7
Attractive Career Option
Having DevOps skills in being considered as a smart career option because of a higher mean salary (i.e. more than 100, 000 USD / year) of software/IT engineers. Moreover, many types of research show that approximately 46% of the IT companies will hire software engineers with DevOps skills8 in the coming years. Some of the key DevOps roles are The DevOps evangelist, The release manager, The automation architect, The software developer/tester, The experience assurance professional, The security engineer, The utility technology player.
DevOps Summary Business Value
The business value of DevOps is manyfold. Implementing DevOps practices and workflows help businesses to increase profits because it saves both time and money. It results in increased software development lifecycle predictability. Moreover, collaboration and communication among team members builds a culture around innovation shared responsibility to motivate teams. Teams have more control over the runtime and are able to deliver software with speed & higher quality using automation and to enhance security via automated testing. All of these benefits demonstrate why DevOps has been adopted so widely at organizations all over the world. It continues to evolve to become an even more valuable operational paradigm as security becomes part of the technology landscape, leading to the rise of DevSecOps.
The DevOps Evolution Into DevSecOps
As DevOps has moved to the forefront of team development paradigms, DevSecOps has emerged in recent years as a step to integrate security into the software development life cycle early on, contrary to the practice of building security at the end. DevSecOps is DevOps with a new vision that balances the need for speed and agility of enterprise IT capabilities with the enterprise’s need to protect critical assets, applications, and services.9
