Rise of a New Star: ‘Devops’
It’s the 21st century and companies have already started using DevOps principles in their culture and hiring DevOps Engineers on their teams. However, do we really know what DevOps is and how it came to be?
Companies often confuse this role as something between a Site/System Reliability Engineer and a bridge between the Development and Operations teams. Neither is a true representation of DevOps. The coined term functions differently as illustrated below.
The Start of DevOps
The term was coined almost a decade ago in a continuation project from the Agile family. DevOps was born from the collaboration of developers and operations leaders who gathered to express their problems, queries and ideas about their project-work in companies and how to achieve it. The power of DevOps is in the culture that supports it, shifting the mentality away from silos.
Transforming your organization to include DevOps culture isn’t as simple as buying some new enterprise software system. DevOps isn’t a singular product – it evolved from the need for adaptation and continuous improvement. This means that the DevOps transition process is never truly finished. The system itself should be in a constant state of evolution and improvement. DevOps teams are comprised of cross-disciplined team members that are all working towards the singular goal of working better together.
To speed up the software development life cycle and its delivery methodology, we have all implemented a form of Agile, which has likely extended into other departments as well. DevOps evolved from the existing SDLC strategies in response to the business models. Traditional waterfall models were replaced with an Agile development model. This was more suitable for a frequently changing environment, achieving faster business results to meet development goals. With a shorter sprint and using a base of release cycles, all teams can work on business and customer feedback quickly as well as fix any bugs for the next sprint cycle.
While agile approaches brought agility and faster delivery, they lacked some processes and practices. There was less synchronization, so it was lagging the release cycle deadlines, which eventually gave rise to a new Start called DevOps. With DevOps we have Continuous Development, Continuous Testing, Continuous Integration, Continuous Delivery, Continuous Deployment and Continuous Monitoring throughout the phases and pipelines. This provides better customer satisfaction meeting both the business model and the organization’s needs. Overall, this created higher speed, more reliability, better communications and collaboration between teams.
Agile and DevOps are both iterative methodologies that focus on moving quickly. With Agile, you are trying to test your assumptions as soon as possible so that one can fail early and fail fast. With DevOps, you are creating a culture of continuous improvement, automating everything and trying to bring value to the customer as soon as possible.
DevOps can be thought of as an evolutionary outgrowth of Agile. It’s exposing new audiences (IT Operations) to the Agile way of thinking and doing things.
This new Paradigm of Agile + DevOps comprises of six key elements:
- Lean thinking
- Product-oriented teams
- Microservices architecture
- Automated governance
- Value stream management
Ultimately, Agile with DevOps is a critical way of thinking that requires a cultural and technical shift in the organization it serves. People within the organization need to understand what their roles are for delivering value to the customer. A software engineer will create a product that’s going to be used by customers. By the same token, operational folks that are hosting, managing, and enabling the production of software, need to realize that they are also serving the customer. In order to keep pace with market demands and pull ahead of competitors, the whole organization must get on the same page about delivering value to the customer.
This DevOps Transformation will bring faster service delivery, visibility across all platforms and data which is eventually a cost-effective service. This process is tailored based on the needs of the projects and organization.
