The Value and Essential Practices of DevOps
DevOps is an evolving philosophy and methodology that encourages faster, better application development and faster release of new or revised software features or products to customers. The practice of DevOps also ensures the application development teams and their IT operations team counterparts to have smoother communication, integration and visibility.
This relationship between “Dev” and “Ops” is important to every phase of the DevOps lifecycle, from early software planning to code, build, test, and release phases and on to deployment, operations, and ongoing monitoring. This relationship drives a continuous customer feedback loop of further improvement, development, testing, and deployment. One of the results of these efforts can be the more rapid, continual release of necessary feature changes or additions.
Along with its efforts to break down barriers for communication and collaboration between the development and IT operations teams, a core value of DevOps is customer satisfaction and the faster delivery of value. DevOps is also designed to push business innovation and the drive for continuous process improvement.
Adopting a DevOps Strategy in Digital Era
Responding in real-time to opportunities is the essence of why DevOps continues to gain adoption across organisations today, there is a need to become more DevOps-driven to keep up with the fast pace of application and platform improvements needed to stay competitive and relevant in digital era. Adopting DevOps best practices and plans can help businesses in time and cost saving, build a corporate culture around innovation and increase productivity.
Quite a few of IT operations are monotonous and repetitive tasks. Most of them can be automated using scripts, but if the situation differs, the script fails and the situations in production vary quite a lot. Implementing DevOps principles help ensuring infrastructure stability and greatly reducing the amount of time and effort spent on monotonous tasks. By breaking down DevOps strategies, it's possible to create a metrics-driven roadmap to value that quantifies its financial contributions over time.
Experimentation is one of the technique for improvement and innovation. However, when system reconfiguration is a long and effort-consuming task, the cost of error is too high and this is a typical problem for many legacy infrastructures because they are full of silo areas that nobody dares to venture. Due to the fact that the legacy infrastructures are high risk, most organisations avoid changing it as it might cost money and effort. This is where DevOps comes into play in solving this situation as DevOps culture values creativity and experimentation and try to find ways to improve the current IT system.
DevOps engineers can run virtualised infrastructures, where servers are treated with care and high attentiveness. They can be provisioned, run and shut down in a matter of seconds, with almost zero costs, as compared to lengthy manual configuration. There is a very little cost of error and in the DevOps culture, failure is not based on someone’s ideas or decision but it is simply an indicator that the IT system can be further improved. They continuously identifying and collecting information about issues that may involve in their IT system to ensure there is room for improvement.
When DevOps allow their engineers to be creative and innovative, they are motivated to develop better application, instead of taking the easy way that might cause technical debt. DevOps engineers are always keen to learn something new and test the latest versions of tools they use, in order to find new ways to improve the product and their workflows. The teams are able to gather and share lots of experience right away, so they grow professionally very quickly. They will not be stuck with the same processes and tools for years and eventually lose their motivation.
Role of Enterprise Architecture in DevOps Adoption
Due to the rise of Agile culture, the approach to organisational efficiency shifted from slow and steady to fast and flexible. In order to maximise the DevOps deliverable outputs, unusable processes should be replaced and this has enabled for DevOps and EA to work together. EA ensures that DevOps are integrated in mutually beneficial manners to establish processes that are built using relevant technology and data sources. EA is able to reconceptualise any sluggish designs or smoothing out any rough patches in the communication channels across various stakeholders involved and ensure the smooth sharing of system to be effective so that the DevOps team can perform with the high standards of efficiency based on the EA best practices. EA and DevOps need to work together to support the organisation itself.
EA provides understanding of business needs, existing technology and the technology investment that are involved while DevOps helps in providing solution guidance of the EA recommendations to the stakeholders. Together, these critical roles can develop, support and establish IT strategies that can help the organisation to succeed.
