What Is DevOps and Why Does It Matter?

What is DevOps
The frustrations that come with having distinct development and operations teams have been encountered by most enterprises. Both teams have their own techniques and procedures, and during design and change control requests, these teams can dispute. For large enterprises, DevOps offers various advantages, including automation, faster code testing and deployments, and the ability to combine operations and developers to expedite the entire change control and promotion process. If you’ve considered forming a DevOps team, here are several reasons why the first investment is worthwhile.

What exactly is DevOps?

In a conventional IT context, operations was responsible for all infrastructure setup, including new hardware installation, configuration management, and user rights assignment. All code-based initiatives were handled by developers, including database development, software design, and code changes and deployments. The two teams only communicate when developers require modifications to infrastructure configurations in order for software to execute or when new infrastructure is required for development.

With DevOps, the two teams are united and work together on code delivery and integration, usually using the Agile technique. DevOps differs from traditional IT in that most of the code testing and deployment is automated. While some human contact and testing is still required, firms with several developers and code changes can test and deploy more quickly using automated tools rather than waiting for monthly updates. With the proper DevOps team and automation tools, organizations can decrease testing and deployment timelines to just a few hours.

DevOps is more than just a set of procedures. DevOps is a shift in an organization’s mentality and culture. Rather of having separate operations and development teams, DevOps pulls the two together to form a single team dedicated to more effective and speedy code distribution.

Benefits of Creating a DevOps Team

Most organizations want to know the benefits of changing current procedures before diving into what constitutes an effective DevOps team. Building DevOps and altering IT culture needs extensive preparation and the creation of new procedures to replace existing ones.

DevOps provides firms with various advantages over traditional IT segregated divisions for a variety of reasons. The following are some of the advantages and benefits that DevOps brings to businesses:

  • Collaboration should be improved. In the past, operations and development collaborated to release software, although this typically necessitated coordination and agreement on how it would be handled, as well as selecting a time when both departments had time to deploy. This slowed down the process, costing firms money and causing frustration among employees. Collaboration on all projects is more streamlined and easier for everyone when both teams work together.
  • Scalability. As the company grows, infrastructure and software should be based around scalable solutions. New resources must be allocated, and software features must be added to handle extra clients. When both departments work together, these two scalability requirements can be effectively controlled.
  • Flexibility. The importance of microservices and containership in development has been recognized by many businesses. Operations often deploy and configure cloud resources. Many of these stages may be automated with DevOps, giving developers and operations staff more flexibility in how deployments are carried out.
  • Reliability. DevOps teams may construct a more stable platform by working together. For example, operations no longer provides infrastructure without first determining how developers would use it. If the resources allocated are insufficient for the software, another round of change control and provisioning is required. This causes delays and inconveniences for all parties involved, but DevOps provisioning as a team will ensure that sufficient resources are available for software performance.
  • Speed. Not only are infrastructure resources designed to support software performance, but DevOps also enables faster testing and deployment.Rapid development necessitates automation, and DevOps’ primary purpose is to automate as much of the development lifecycle as feasible.

Resources and Procedures for DevOps

As previously said, DevOps is a cultural shift, and many of the technologies used to manage development differ from traditional operations and software programming solutions. Whether a DevOps team is built from existing personnel or new hires are hired, the automation process will be integrated into existing processes.Automation will relieve both teams of a significant amount of overhead and free up resources to be employed for other purposes. Developers have more time to code, while operations workers have more time to deal with other network issues, thanks to automation.

  • Expect the following solutions to be introduced to the development pipeline when forming a DevOps team:
    1. Tools for continuous integration and delivery (CI/CD). These tools represent a significant improvement in the time it takes to test and deliver new code. It’s also one of the changes that affects how developers test and deploy code, therefore it’s a shift in developer culture. Before being introduced to a testing team or production, these tools make codebase updates after developers check code and indicate any mistakes identified. This provides developers with faster feedback on any upgrades and modifications, reducing the likelihood of errors later in the development cycle.
    2. Automated cloud provisioning. When developers needed infrastructure changes in the past, they would submit a request to IT and wait for clearance before provisioning. Developers no longer have to wait for resources, and IT no longer has to provision them manually, thanks to a collaborative DevOps team. Most cloud providers include capabilities that automatically scale up or down based on resource utilization, and provisioned resources can be included in automation scripts.
    3. Microservices. The way code is written is evolving, and microservices break down a monolithic codebase into discrete movable elements that work separately but in tandem. Containers run components of a monolithic code base so that they may be controlled individually rather than having to update the entire application when code changes, which could cause the entire environment to fail if mistakes are introduced. Container provisioning may be automated using orchestration tools like Kubernetes when code changes inside each application component.
    4. Management of configurations. Changes to setups, like cloud provisioning automation, can be automated rather than requiring human interaction. For example, if a new environment variable is required for software deployment, automation techniques can be used to update it.
    5. Monitoring and logging are both required. Cybersecurity and exploit detection, error logging and remediation, compliance rules, and resource utilization analysis reporting are all reasons for monitoring. If a business doesn’t have intensive monitoring on an application now, it will be required once automation is included in deployment and testing. Monitoring informs developers about potential issues with the program, allowing them to address them more promptly, especially if the mistakes are critical to the application’s functionality.

DevOps Misconceptions and What It Can Do

As anyone may anticipate, DevOps isn’t a panacea that will address all of the world’s issues. The people that make up a DevOps team, the procedures in place to organize and manage solutions, and the automation technologies used to test and deploy are all factors in the team’s success. DevOps does not assume full responsibility for development, but it does eliminate many of the human errors that manual deployments and testing present.

  • One of these roles is DevOps. A DevOps team is a group of people from various positions who work together to improve the overall stability, dependability, and performance of the software development lifecycle. Although the DevOps team functions as a unit, each member has their own position and duties.
  • DevOps is reserved for major corporations. In fact, the automation and decrease of human costs is ideal for smaller businesses who lack the means to hire dedicated code deployment and testing personnel. Automation software is not expensive, and some of it is open-source. DevOps can help any firm of any size save time and money when it comes to development, testing, and deployment.
  • DevOps is a one-way street. When working with DevOps teams, best practices should be followed, but processes and the manner the team executes deployment can be adjusted based on business needs and employee preferences.
  • DevOps is nothing more than a set of automation tools. DevOps is, in fact, a philosophy and IT culture that promotes transparency and efficiency throughout the software development and lifecycle. Although automation is an important part of the process, it is not the sole one. DevOps strives to alleviate many of the conventional software development challenges that have caused delays in updates and friction between developers and operations.

Where DevOps Is Most Beneficial

The daily grind of design, code, test, deployment to staging, quality assurance (QA) testing, and promotion to production is familiar to most developers. DevOps automation technologies help with testing and deployment to staging and production environments.

The most important ways DevOps aids software development in any firm are:

  • Detection: The automation’s monitoring and logging tools detect any anomalies or errors and notify the responsible parties. The codebase is generated automatically and put to the test using benchmarks. By discovering faults earlier in the development cycle, developers are aware of their errors and may correct them before deploying problematic code that could create production issues.
  • When mistakes cause the program to crash or interfere with the user experience, developers must act swiftly to fix the problem, or the business could lose thousands of dollars in revenue. Despite the fact that DevOps aids testing, developers must still respond to serious concerns. DevOps reduces incident response times by monitoring and discovering problems early in the process.
  • Correction: No developer wants to release faulty software, but mistakes do happen. Developers can more rapidly resolve any issue in staging and production by leveraging automation during the testing process.
  • DevOps automation solutions provide analysis of all elements in the testing and deployment processes, allowing the team to optimize the entire lifecycle.
