Devops is not just a portmanteau.
Comprehending devops extricates a cohesive and collaborative work environment between development, validation and deployment operations – maneuvering which offers predictable outcome by way of enhanced reliability, stability, and resilience leading to customer satisfaction. Devops is the medium which merges development, quality assurance and operations at the perfect focal point to generate maximum customer satifaction and maximum business value.

Devops is a set of practices that reduce time to market without compromising quality. By making frequent deliveries to customer and incorporating changes and improvements from the feedback we can help build a product which is highly reliable and stable. From our experience in developing and delivering enterprise software we know and understand the areas which contribute to delays in various stages of software development life cycle.
How do you transition to devops from existing development, test and deployment processes and infrastructure? Which are the right tools that may augment this transition? Devops is a culture change and you cannot do that in a day or hire a separate team to do devops and get overnight results. Devops adoption must not be abrupt but gradual.
We help customers identify and eliminate constraints which are limiting their organization in achieving its goals rapidly. Our objective is to focus on:
1. Identify bottlenecks in application life cycle by charting out a value stream mapping.
2. Automate infrastructure provisioning and configuration to reduce lead times.
3. Implement a deployment pipeline to achieve rapid delivery.
4. Help teams incorporate devops practices.
Value stream mapping helps identify value and non – value adding times to application life cycle and devops will enable rapid and reliable delivery of application reducing the time to market. Devops practices will encourage collaboration and communication between teams to eliminate time waste, will develop strong feedback loop between various stakeholders and automating many of the repeated tasks will ensure faster time to market. Continuous integration, continuous delivery and continuous deployment will make sure that it doesn’t take weeks for feedback to arrive back to developers.
DevOps practices permeates all of application life-cycle to reduce the time to market. The most important principles of devops are to reduce isolated development environment, eliminate tasks which are not adding value to the business and the way this is achieved is by close collaboration and communication between all of the stakeholders, complete automation of build, deploy and infrastructure provisioning process.
We begin by studying the current flow of software from development to production charting out a value stream map. The time taken by software through different processes till it reaches production is a very important measurement. We chart value stream map for development, operations and quality assurance showing the time spent by each on the software before it is passed on. Figure below shows time taken for a single change to reach the build on a development and operations value stream map. This is very effective as we can see and inquire about delays which are impeding faster delivery.
Next we use the collected data to analyse and discover bottlenecks and find out ways to speed up the process.
Continuous Integration: Problems are encountered while integrating code if many developers work on single or even different features without properly coordinating and collaborating with each other. In such scenarios we don’t have any metric to gauge the stability and reliability of the application without developers integrating and merging their code frequently. Continuous integration is required to get rid of development isolation. Continuous integration advocates that all developers integrate their code continuously to the mainline and ensures that code that works on developer’s machine also runs in other environments. As soon as developer commits his code the Continuous Integration tool will fetch the latest code from source repository, run all unit tests on whole of the source code belonging to other developers as well, once it passes, build tool will compile the code and create build to be provided to next stage in deployment pipeline. In case of failure, build is marked as failed and it is easy to pinpoint the code that caused failure by checking the unit tests which failed.
Continuous Delivery: Continuous delivery is the capability to automatically deploy application to any environment. Once build succeeds, application needs to go through a series of testing stages, each of these testing stages has production like environment. Deploying the application in any of these testing environment requires automatic provisioning and configuration of environment, installation of application and running automated tests.
Continuous Deployment: Continuous deployment is the decision to automatically deploy application to production to get customer feedback. This is very important and one should have the capability to do this at any time when asked for.
Infrastructure automation and monitoring tools play an important part in devops and we make sure to equip ourselves with a wide variety of tools. It is very important to understand that Devops is not a specification or a product or a job title but following a devops practice upholds your commitment to the customer, product, your work so much that you communicate, collaborate, automate and measure everything so that your company is able to deliver rapidly and efficiently. Developers and system administrators need to cross over to and incorporate each other’s skills and knowledge areas to deliver the value faster to the customer.
