What You Need To Know About DevOps?

What is DevOps?

The culture of DevOps is one of the latest trends in software development. It involves developers partnering with operations staff to ensure that the software operates with minimum problems.
Today, several companies find themselves in an awkward situation with the increase in cloud-based web applications which allow for quick responses to the requests or issues coming from the user community.

The goal of every software development firm is to ensure adequate responsiveness to their user base, but it can subject a lot of pressure on the functional teams within an organization. This pressure often causes more defects and disruption to the team.

Therefore, DevOps tries to solve this common problem by creating an essential partnership between Development and Operations (in fact, this was the motivation behind the name).

In this structure, the development teams are obliged to support operational requirements such diagnostics, deployment of scripts, and load and performance testing from the start of the cycles. On the other hand, the operations team offers knowledgeable feedback and support before, during and after deployment.

Many software development teams are currently adopting DevOps in their organizations. They need to establish this culture given the strain organizations undergo to generate high-quality codes quickly with limited time available for quality assurance.
This is a new environment, and all developers will have to adjust if they want to succeed. With compressed timelines, the walls separating development, quality assurance, and the production are key barriers to agility.

DevOps tries to break through those major walls. Now, team-playing skills are as essential as technical expertise. Therefore, it’s the primary focus on the end-user experience and the way it affects the business.
Instead of going for a new set of tools or business, DevOps provides a new culture and process. It’s the development, quality assurance and operations working together to expedite problem resolution and development as well.

Why Developers Need DevOps?

DevOps is ideal for all software developers. There are three main reasons a developer would prefer to work in a DevOps-oriented organization:

1. A Better Quality Of Life

Developers who’re always operating in Ops-mode receive few calls at midnight to settle production problems. That is because they can identify problems before they become catastrophic due to a proactive monitoring orientation rather than the reactive alerts.

2. Pride of Ownership

In a traditional software process, once a developer has created the software, it is “thrown over the wall” for quality assurance and later thrown over another wall for production. Therefore, what the end-user finally sees might be quite different from the original composition of the developer.
But under development and operations model, what you develop goes live since you continue to have access and excellent visibility to the code even after it goes to quality assurance and production. That means developers own the delivery process of the code from its creation to execution.

3. More Relevant Work

Developers, like many humans, get more satisfaction from work which has high relevance in the real world. Since developers in a standard organization are isolated, they usually work on simulated issues in made-up user situations and they only discover that their approximations were wrong once something breaks.
In a DevOps model, situations are real. For instance, environments are load tested, -before they are put into production -to determine if they work properly. Also, the test scripts are themselves, tested for practicality by being used in the production setting, not test labs only. Sharing these significant test results with the developers provides them a perfect opportunity to know how their code performs under real-life situations.

What Does “DevOps-Ready” Means?

Three questions can assist in clarifying where you fit on the curve:

1. As a developer, do you have access to troubleshooting information in real time?
2. Does your production phase use tests and some other tools from the development team to confirm that the production phase is functioning?
3. As a developer, do you consider the networking team as your partner?

If the answers are “no,” you aren’t there yet. Here are some essential things which can be done to improve the current situation. Let us start with your tools. Even though DevOps is more about process and culture than an organization, tools can assist in enforcing the best practices. Particularly the sharing of troubleshooting information across the silos.

That needs adding more instrumentation in your software to discover how your software is performing in quality assurance and production, not only in development. This is the code which reports function timeouts, checks system parameters, traps errors, and returns other values during execution of the program, which it then writes to log files.
In a siloed setting, developers often will not see these log files once the code is released into production. In a DevOps world, developers have enough visibility to the files no matter where the software is run -in development, quality assurance, or in production.

Not only do the defects get fixed quickly, but similar defects are less likely to reemerge in the future releases and thus, making the development, itself, quicker and more responsive to the overall business. That delivers agile quality to agile development.

Breaking Old Habits

Involves such as the natural tendency to concentrate on software bug counts as a quality measure. Fixing one bug won’t offer much leverage for developing bug-free software quickly. A better measure is the process bug counts. So, where’s the process broken which led to the bug in the first place?

For instance, is the code which developers are creating on their local machines a bit different from the code which gets deployed to quality assurance or production? Or is the code performing differently in one setting since there’s something present there that isn’t available in the other environments?

Unless the versions of the code are synched tightly across the environments, or the environments themselves are synched tightly, it’s difficult to determine whether a problem is an environment problem, a data problem, a logic problem, or something else. In fact, this is another circumstance where tools can impose consistency as in automated deploy to push a similar code to many environments all at once. Finger Pointers or Partners? Perhaps the most essential adjustment developers will have to make in their daily interaction with other team members. Do developers handle software problems proactively (such as by monitoring all operations logs every day) or do they wait for issues to come to them through support? When there’s an issue, how is it resolved? Are team members finger pointers or partners?

Leadership matters a lot -whether management is inculcating the DevOps vision, leading by example, offering the necessary support and training, and rewarding the developers for team contributions, not only technical prowess.

DevOps needs an orchestra leader. If that job is not filled yet where you work, maybe you need to apply. For you to sell an environment, you must understand what is significant to management: Is it about the developers being more accountable for their code? Is it moving higher quality? Is it moving faster? You can achieve all these things by way of a development environment.
