What is DevOps?
DevOps is a combination of software development and IT operations, is a cultural and professional movement that stresses communication, collaboration, and integration between developers and the operational team. The ultimate goal of DevOps is to deliver information systems faster; at both organization and team levels. While the techniques involved are still evolving, few people inside an organization can define its exact practices or goals due in part to its fluid nature.
In a nutshell, DevOps is a culture, movement, or practice that emphasizes communication, collaboration, and integration between software developers and information technology (IT) professionals. It was started by a group of engineers who noticed a problem in their environment.
DevOps has become a popular approach to software development. In this article, we’ll cover what is DevOps and what are the approaches to achieve it.
Advantages of DevOps
- Speed. DevOps practice lets you move quickly on the need to innovate, better adapt to markets, and become more efficient at driving business results.
- Fast Delivery. When you increase the speed of release, you can quickly improve your product and create a competitive advantage.
- Reliability. DevOps practice applications such as continuous integration and continuous delivery can ensure the quality of application updates and infrastructure changes so you can reliably deliver faster speeds while maintaining the maximum experience for end-users.
- Improved collaboration. Under the DevOps model, developers and teams operation teams collaborate closely, share responsibilities and integrate their workflow. This reduces inefficiency and saves time.
- Security. You can adopt the DevOps model without sacrificing security using automated, integrated security testing tools.
How to find the right DevOps tools
DevOps Practice relies on efficient tools to help teams quickly and reliably identify and innovate for their customers. These tools should automate manual tasks, help teams manage complex environments on a scale, and keep engineers in control of the high-velocity speeds that is called DevOpsits workflow consists of phases;
- Planning the product’s development.
- Building the code.
- Testing and deploying.
- Delivering product updates.
- Monitoring and logging software performance.
- Gathering feedback from customers.
Planning: Planning the schedule and task tracking tools are needed to sure that the DevOps team knows what tasks are at hand, what is currently being done, and whether there are any risks of falling behind schedule or not. Tools such as Confluence and Jira help DevOps teams achieve a seamless and effective project management cycle and ensure timely product delivery.
Build and delivery: Developers need to quickly deploy a development and testing environment and can’t wait too long to repair when something goes wrong. Docker containerization ensures consistency in multiple developments and release cycles and provides an environment for repetitive development, construction, testing, and production. Other popular tools at this stage include cabernets, terraform, chef, counter, and puppet.
Testing: Look for tools like Jenkins, Circle CI, and GitLab CI, which help reduce testing time and effort without compromising code quality or user experience.
Monitoring and logging: This phase includes performance analysis and logging, alerting on various issues, gathering user feedback, etc. Tools for performing these tasks include; Grafana, Flexible (ELK) Stack. Splank. Sumo Logic., Prometheus.
DevOps security and DevSecOps.
DevOps Security, commonly referred to as DevSecOps, refers to the discipline and practice of protecting the entire DevOps environment through strategies, policies, processes, and technology.
Traditional security operates from the position that once a system is developed, its security flaws can be detected and corrected before release. With the change in the DevOps model, the traditional security mechanism occurs much later in the development cycle and is much slower to design and release software built through iteration. As such, they can become a major obstacle to the rapid delivery of applications and services.
With DevSecOps, security becomes the focus of everyone’s attention in a DevOps team.DevSecOps aims to implement security decisions quickly and on a large scale without sacrificing security. DevSecOps includes ongoing, flexible sharing between release engineers and security teams. The concepts of “Speed of Supply” and “Building Safe Code” have been integrated into a systematic process. Security testing is repeated in iterations without slowing down the cycle.
How do you deal with DevOps challenges?
Adopting DevOps could be the biggest change you will ever make to your IT organization. However, DevOps is not a single strategy, nor is it a list of tools or techniques. The mission of DevOps is to unify software developers with the organizations that operate the computers on which their code runs.
The reality is that organizations embarking on a DevOps transition look very different. This makes it natural for people to want to understand their peers’ approaches so they can make more informed decisions about how to adopt DevOps at their organizations.
Some of the challenges they run into are that sometimes an app or microservices architecture for example uses technologies that might be a little bit new or different than what people are more used to using in an IT environment. Other times it’s because they’re using broad open-source tools where there aren’t established strategies for use in production environments. Or that legacy of applications and the desire to modernize them also adds additional challenges to existing operations teams.
DevOps methodologies/How does it work?
DevOps is like a descendent of agile software development, which is born from the necessity to stay up with increased software development velocity and throughput agile methods.
Advances in agile development have highlighted the need for a more comprehensive approach to the life cycle of software delivery, resulting in DevOps.
“Agile development” is an umbrella term for many repetitive software development methods, many of which have reached DevOps.
- Scrum- Is a frame that can address the complex adaptive problem while delivering a high-value product
- Kanban- is a way to manage product creation without putting pressure on the development team by emphasizing preparation. Like Scrum, Kanban is a process designed for support teams to work together more efficiently.
- Extreme programming (XP): A software development approach aimed at improving the quality of software and changing the needs of users. XP supports continuous releases in short growth cycles, aimed at improving productivity and introducing checkpoints where new customer needs can be met. Other elements of extreme programming include programming in pairs or extensive code review, unit testing of all code, not programming features until they are needed, flat management structure, simplicity, and clarity of code, customer over time. Expecting a change in needs passes and therefore the problem is better understood, and there’s frequent communication with the customer.
