It's all about time, more precisely — person hours. Once it turned out that someone equally well-versed in software development and IT could work faster and better. Because the programmer does not need to "put in his brains" to the system administrator and vice versa, first, such one-person bands appeared, and then the methods and tools took shape called DevOps.
DevOps: Development + Operations
DevOps is a software development approach emphasizing collaboration, communication, and integration between software developers and IT operations professionals.
DevOps Experience
They have very intelligent people on their team — people that I would gladly hire and pay for myself.
It is a combination of "development" and "operations," aiming to break down traditional silos and align the goals and responsibilities of these two groups. DevOps is defined by a set of principles and practices that promote a culture of shared responsibility, continuous improvement, and rapid delivery of high-quality software.
Teamwork
All sports teams now have a person with a laptop who drives the players' actions on the pitch into the statistical program when the game starts. These are the stats; they want their team to win.
Then the program will process the work results and transfer them in graphs and figures to the head coach. Imagine a situation in which the coach does not know how to use statistical data: he is elderly and does not know computer skills, does not trust programs, and writes everything on paper. But he also wants the team to win.
In which case is the team more likely to succeed? If the coach starts to understand computers and the stats, they know how to give him data, like on paper.
It's strange, but until a specific time, programmers and system administrators worked in complete isolation. But both wanted the product to work well; for the team to win. The philosophy of mutual understanding is the main essence of adopting DevOps.
DevOps vs. IT
DevOps differs from traditional IT methodologies in several key ways:
DevOps seeks to bridge the gap between development and operations, enabling organizations to deliver software more rapidly, reliably, and with higher quality.

What Is Important for DevOps
The core principles of DevOps are based on continuous improvement:
1. Culture of collaboration — development, operations, quality assurance, application of security, and other DevOps teams work together throughout the entire software delivery in the DevOps lifecycle.
2. Team development can reduce errors, increase efficiency, and achieve faster delivery times by automating repetitive tasks like building, testing, and deployment.
3. Continuous integration and continuous delivery (CI/CD) — the approach helps catch bugs early, reduces the risk of integration issues, and allows for rapid feedback.
4. Infrastructure as code (IaC) treats infrastructure provisioning, configuration, and service management as code, enabling teams to automate the setup and project management.
5. Monitoring and logging — collecting and analyzing data for the detection and resolving issues; it's also helpful to make high-performing and data-driven decisions.
6. Continuous learning — teams regularly reflect on their processes, gather feedback, and seek opportunities for improvement. They embrace failure as a learning experience.
7. Security is a shared responsibility, with considerations integrated into the development, continuous testing, and deployment processes.
These items are not rigid rules but guidelines that help organizations build a DevOps culture and adopt practices that align with their goals.
DevOps provides a reliable infrastructure.
Why the DevOps Approach Has Become Important
The DevOps approach has become necessary because it aligns with modern software development and operations demands. It enables companies to deliver products more quickly, efficiently, and reliably while promoting collaboration, automation, and continuous improvement. By embracing DevOps, firms can stay competitive, meet customer enablement, and drive innovation in an increasingly fast-paced and dynamic technology landscape.
What Can a Business Get from DevOps?
Implementing DevOps provides the benefits for businesses:
• DevOps projects make shorter time to market
• Increased efficiency and productivity
• Scalability and flexibility
• Cost savings
• Continuous innovation
• Improved risk management
The benefits contribute to business growth, customer satisfaction, and a competitive edge in today's fast-paced and technology-driven market.
High Level of Collaboration
Working in the DevOps style is similar to a neural network functioning, where the decision-making nodes are interconnected, and the result of the work of one affects the other.
DevOps aligns development and operations teams toward shared business goals and objectives. By including representatives from different areas, teams gain diverse perspectives and insights. Meetings, stand-ups, and collaboration tools facilitate the exchange of info, status updates, and feedback. Operation engineers provide input during design and extension, contributing technical expertise in scalability, deployment, and infrastructure requirements.
DevOps Increases Motivation
Even if we take an abstract company that has nothing to do with software, then the cross-knowledge of department employees already increases work productivity. And if the software is needed, teams understand it at a high level and constantly exchange data; this approach improves the product and the team's atmosphere.
Unplanned work is an essential factor in the DevOps culture that affects the morale of teams. It refers to all optimization processes and global changes in the project that were not part of the original plan. A developer's time spent fixing a bug falls into the category of unplanned work. You can increase team motivation by creating a system to respond to this category of tasks proactively. It will help engineers and developers get into the DevOps philosophy because, finally, they will work better and faster.
The Most Popular DevOps Tools
DevOps is not a straight highway that leads from point A to B. It is a road with many intersections where you can turn in the right direction. The main thing is to know the trip's purpose and the developed route. Much also depends on the car's power, such as travel time.

All around is automation
Almost all of these tools, to one degree or another, are related to the automation of the development, test automation, and continuous deployment process. Automation eliminates bottlenecks and large amounts of manual labor. In addition, along with the automation of processes comes their standardization, which further reduces the likelihood of errors. During automation, DevOps specialists collect tools used at different application lifecycle stages into a single system. At the same time, transparency of processes is ensured, a high speed of release of new versions, and deployment of projects is simplified.
First, you need to come up with a strategy
We have listed the most popular DevOps practices: continuous integration and delivery, IaC, communication, collaboration, etc. Another thing worth mentioning is microservices. In DevOps, they refer to an architectural style and approach to software development where applications are built as a collection of small, loosely coupled, and independently deployable services. Each microservice focuses on a specific business capability and can be developed, deployed, and scaled independently.
There remains the core base practice — the choice of strategy. Working conditions are changing; new tools and services are emerging. Therefore, it is necessary to focus on the core concepts that allow companies to grow their business through DevOps best practices. Only after you prioritize the missing elements of the plan can you choose the right tools.
One team may not be enough to implement a high-quality product. You can rely on DevOps tools and managed services when it makes sense. It is necessary to save staff time, understand the user experience and needs and put efforts at the right point to create custom tools and rely on third-party tools and services in the rest of the plan. Some companies offer DevOps as a service. DATAFOREST is one of them, with some success stories.
