What is DevOps for beginners?
Many IT professionals often ask themselves and what's it all about.
Some even think that it's just another marketing buzzword, but it's not! It's a real movement, which has received a lot of attention in recent years, and can provide a lot of opportunities to save money and time on projects, while increasing productivity and quality of software. And it's not just about the word DevOps - there are several concepts that are very helpful to understand what this approach is all about. So, let's take a look at them.
What is DevOps? Let's start with the main concept of DevOps - the Dev and Ops teams working together. The DevOps team is responsible for developing and maintaining the product, while the Ops team is in charge of all the other infrastructure-related tasks, such as server management, system administration, backup, etc.
When the teams work together, they have a common goal: to deliver the product as soon as possible, with high quality and less effort. The Dev part of DevOps means that the team is composed of developers - this includes developers who write code, as well as testers. The DevOps approach is very different from traditional waterfall development, because it focuses on building systems that allow developers to work quickly.
The DevOps approach focuses on building systems that allow developers to work quickly. The Ops part of DevOps means that the team is composed of system administrators, which include developers who are responsible for designing the system architecture, as well as developers who are responsible for building it. The Ops team should be a part of every project, because it's responsible for managing all the technical aspects of the system.
Both teams - the Dev and Ops teams - work together, but they have to coordinate their work so that the product will be delivered on time. The DevOps approach is very beneficial for the business, because it makes it easier to release new features, as well as to fix existing ones.
What is Continuous Delivery? Continuous delivery means that the new version of the product will be released to production as soon as it's ready, without taking into account any bugs that might be found during testing.
Is DevOps a programmer?
A couple years ago, I saw a talk by an engineer at my university about a new practice called DevOps.
Devops is a concept that's used to describe the way you can use the software development lifecycle to work more effectively. In one of the talks the speaker gave, the talk claimed that a person who knows how to use tools like Git and Jenkins can pretty much be called a DevOps person. But the definition in the article made this look like DevOps is a person. I have not heard this definition anywhere else before so I wonder if there is some sort of a history behind it or why someone would say that.
I tried looking at Wikipedia but they don't have a very coherent page for what is DevOps. They seem to only cover the use of containers and their relationship to other tools. They have pages about some aspects of software development, but I don't see anywhere that the DevOps practice is linked to being a programmer.
Does someone have any ideas on why people are now starting to refer to a person being called a DevOps person? 1 Answer.
My impression is that if you are using these sorts of tools - namely git and Jenkins and docker and Kubernetes, all of which I believe were coined by the open source world - you are using the practices of DevOps. It's not really intended as a technical term per se. (Though the 'Dev' is technical.)
The term itself has taken on a wider meaning over the past 10 years or so. In the start up community it was used to describe anyone using version control, CI, etc. (in addition to the engineers themselves, but also QA people, security people, .). Then it started appearing in marketing copy and in articles about dev operations. It's still not a technical term though.
In most places it seems to mean something closer to "we're doing DevOps!" or "I'm DevOps" rather than "I am a DevOps person". So no, I don't think the term has any basis as an engineering concept. There is the implication, I think, that we are all programming these days and that DevOps is an evolutionary way of running production.
What is DevOps vs agile?
The DevOps movement has had a great deal of attention in recent years.
So what exactly is it?
Let's start with the most common example of DevOps: Automated builds, deploys, and tests that can be deployed quickly. These are certainly some of the key benefits of DevOps, and if you're using one of the popular DevOps tools such as Jenkins or Bitbucket pipelines, you've already implemented a good portion of DevOps. In fact, the only real difference between DevOps and traditional agile is that the former emphasizes automation and continuous integration while the latter does not.
The concept of DevOps was first introduced by Netflix, but it has since been adopted by many other companies to increase efficiency and speed up deployment. Today we'll look at a few of the key benefits that DevOps provides.
Better Performance. The main benefit of DevOps is that it increases the efficiency of the team by making continuous improvement possible. For example, if you run all of your builds and tests against your latest code changes as soon as they're finished, then your team is able to deliver more frequently to a wider audience.
This also reduces the time it takes for development teams to deploy and ship features, which results in faster delivery cycles. DevOps also allows teams to release new features more often because of the increased quality and reduced effort it takes to deploy.
Better Security. Another important benefit of DevOps is that it helps teams to secure their code. If you have continuous integration or automated testing that tests the code for any vulnerabilities, then you can be sure that your code has fewer security holes than traditional approaches. If the test detects a vulnerability, it can be fixed before it reaches production.
It's worth noting that this is true regardless of whether the developer is using DevOps or not. Security is a major concern for all software developers, whether you're using traditional development practices or adopting DevOps. However, DevOps makes this process much easier.
Faster Time to Market. As we mentioned above, DevOps allows your teams to deliver more frequently. This leads to faster time to market, which can help you overcome the challenges that a new market brings.
If your product hasn't been in the market for very long, there may not be enough feedback from customers to fix any issues.
Is DevOps a good career?
- Ask Me Anything!
This interview is made available for a two-week period. You can have it for free, however if you would like to support this website by buying any of the products that we review, they are available below.
Ask me anything about DevOps! What's the coolest project that you have worked on so far? The coolest project that I have worked on so far was the one where our software team had to create a product where they were building an API which has to be secured from the outside world and also has to be able to interact with our internal databases, the backend system. The project involved lots of collaboration between different teams, involving our developers, QA, database developers and system designers. So, working with different stakeholders was really challenging and interesting at the same time.
What do you feel the biggest challenge facing DevOps is right now? I feel the biggest challenge right now is that our DevOps professionals need to get better at working together to overcome the challenges that they are going through when they are trying to learn a new technology. You need a bit of everything when you are doing DevOps. You need to be very organized in the way you organize your workspace, the tools that you use, and the practices that you adhere to. So, a big part of what makes DevOps great, is having the right set of tools and the right practices and methods. And, the biggest thing that I have noticed as a professional is that not everyone does this correctly. A lot of the time, what you will see is that there is no methodology in place, no tools that are being used properly, no practices being adopted by most people. So, a lot of times people who say they are working in DevOps are just really winging it. And, I think as DevOps professionals, we are in a position to be really good at helping each other out, because we know what it feels like, and we know how to do it right. So, just giving people advice is really tough. People should be asking for advice.
You mentioned something in your interview about a person coming to you and saying "Hey, DevOps is great". So, just giving advice is really tough. So, what should someone do to get started?
That's a tough one.
