Everything You Need to Know About DevOps
Is it a technology solution? Is it a culture? A Process? What is DevOps??
With the buzz going around the IT industry, it is easy to assume that it is a technology solution. Being a big wave after agile, people may think it’s another methodology or a process.
DevOps is a combination of better communications, shared responsibility and closer collaboration between development and operations departments as well as other teams in the organization like security, to achieve the least time to market and high quality software delivery. It comprises practices like continuous integration and continuous delivery, automated testing, proactive monitoring, automated configuration management and agile development.
The Sprouting of DevOps:
Unlike its predecessors Waterfall and Agile methodologies, DevOps is not a standardized approach across the entire industry. It takes many forms and differs from one organization to another; project to project.
In Waterfall, team members were siloed quite rigidly. It consumed a massive amount of time to hammer out the numerous challenges from bugs to source code modifications. And then Agile methodology came into picture in the year 2000, breaking the software development into large batches and deploying as a whole package. This enabled the project members to deploy iterative updates, which were relatively easier to modify and reduced the time to market.
If agile is working out, why the need for DevOps? It stemmed from the need to apply agile software development to IT operations and the security ops. DevOps brings many principles from Agile. However DevOps approach always prioritizes automation and keeps its eye on meshing together development and operations as one unit. To stay relevant and resilient, where demands are rising in the modern-day; it is necessary to adapt to an intersection of processes i.e., DevOps.
How do DevOps actually help Companies?
- Improved Build Quality
Due to collaboration of development, operations, testing and security; DevOps provide scope for knowledge and information sharing. It brings together development centric attributes such as features, performance and reusability; and operations centrics attributes such as deployability and maintenance to uplift the overall code quality. Through CI/CD(Continuous Integration/ Continuous Deployment), it achieves not only the initial code quality but also improved testing(load, integration etc).
- Faster recovery
Fastest feedback loop is the Mantra for a thriving team. To resolve issues faster, the teams need full transparency and seamless communication. DevOps approach provides these pillars to minimize the downtime, so that the customer satisfaction doesn’t tank. Open communication helps the teams to swarm on bugs, issues, fix incidents, and unblock the release pipeline faster.
- Better economies of scale
Another principle that DevOps brings to the table is Automation, through which companies can automate monotonous tasks without getting worried about bugs. Development can become more robust and stable through frequent rollovers. With automated functions, companies can cut down large manual costs resulting in monetary savings.
Wavering stability because of new features is always a stone in the bottleneck. Automating infrastructure management allows scalability of the product to meet the load demands without manual intervention. Automated continuous deployments makes them predictable and consistent. Integrating both ops and dev teams will ensure stability throughout the deployments.
- Accelerated application delivery
The combination of shared code base, continuous Integration, test driven techniques and continuous Deployment allows integrating and deploying the code without a delay which improves the frequency and quality of software delivery. It also cuts down the development time from months or weeks to days or even hours, accelerating the SDLC and reducing the delivery timeline. Integrating and addressing security at every stage of SDLC instead of retrofitting at the end will reduce time spent on remediating security issues by half.
Though there are pros that can be outweighed by cons, there are some challenges in adapting to DevOps in organizations.
- As DevOps is not a standardized approach, it can be difficult for organizations to develop unique workflows and toolkits around DevOps. It can be time-consuming and expensive.
- Many entities turn to MSPs to set up DevOps for them, because of the complexity.
- DevOps adoption can become expensive with IT costs such as new hardware and software, and recruitment of skilled DevOps specialists. Though it will be profitable in the long run, early overheads are to be tolerated.
To ease the operational impediments of DevOps, there are some magnificent tools in the market; Ex: Jenkins, Docker, Puppet, Slack etc.,.
DevOps is that change in mindset of looking at the development process holistically and breaking down the silos established among teams. After all, every business’s motto is to deliver high quality products and services to the client and speed is what makes you stand out from the competition.
