Why is DevOps important?

DevOps promotes frequent code versions and makes it easy to detect defects in code. Thus, teams can avoid app failures or defects. Even if a failure occurs, the recovery time is fast because both development and operational teams share ideas. Better teamwork and coordination lead to greater competencies.

What is DevOps centralized?

DevOps consists of various tools like Jenkins or Splunk. There should be a central ized unit for the creation of these tools and operating techniques. The same centralized unit is responsible for implementing agile in the development team. Not only that, the team in charge of that unit must share the most advantageous tools for the company. This team also maintains the tools and creates different guidance programs for implementing DevOps.

Why is waterfall model not fast?

Traditional development methodologies like the waterfall model lack speed. This is because there’s no connection between the teams. When one team finishes its work, the other team is just starting. Companies can create products at a faster pace with DevOps in action. Also, the speed of making enhancements in products is high. When you combine efforts by the development and operation teams, the development cycles are shorter. Thus, this results in faster innovation and brings teams ahead of their competitors.

Why is automation important in DevOps?

Automation is a key instrument to foster software building and testing that helps increase the release speed while avoiding human errors. The adoption of DevOps tools is not enough to implement the DevOps approach. New practices must be adopted as well.

What is DevOps approach?

The implementation of the DevOps approach presupposes that developers, QA engineers and system administrators now work in the alignment with each other. The ongoing communication between the DevOps practitioners allows preparing and delivering new software pieces to production faster and with a decreased number of bugs missed.

How does automation affect DevOps?

Within the DevOps approach, the rate of test automation increases while the number of post-release errors declines. To convince business users of high software quality, it’s important to establish strong communication with them. Business users can be involved in defining the tests to be automated (including acceptance tests as well) to ensure sufficient testing coverage for the software functions that are the most critical for them. Since business users know that software functionality is tested thoroughly, their confidence in the application quality rises. Thus, they lose the need to carry out their own manual acceptance tests afterwards, which reduces the overall lead time.

Why do developers write unit tests?

As unit testing implies verifying software units independently , integration errors or software performance issues may go unnoticed. To check the interconnection between application components, as well as the overall application functioning, software test engineers carry out manual and automated testing via UI. However, the rate of test automation is not high enough to cover even critical functionality.

Why is continuous testing not implemented?

Due to the resulting testing gaps, software users often detect severe post-release bugs. Further, test engineers may not be able to reproduce the identified defects in the testing environment.

How long does it take to fix a software bug?

As the collaboration between the teams involved in the software development process is not efficient enough, it generally takes 2-4 weeks to detect and fix bugs or implement and release minor changes in the software. Such a long waiting period is especially harmful when software under development is supposed to support or transform critical business operations, for instance, if it is a supply chain management application or a CRM software.

What is software development?

2. Practice Agile methodology

Agile has been in practice for decades, and there are hardly any non-Agile enterprises today. It is also a prerequisite for introducing DevOps.

4. Implement test automation

Test automation is an essential DevOps best practice as it enables continuous testing in the DevOps lifecycle. Continuous testing refers to testing early in the pipeline, testing often, and testing across different environments and devices. It aims at ‘failing fast’ to catch bugs early as they are easier and cheaper to fix earlier in the pipeline.

5. Switch to microservices architecture

Microservices architecture divides large, complex applications into simple, independent projects. The individual components, scoped to a single purpose, operate independently of each other and the application as a whole. They are deployed as independent services and communicate using application programming interfaces (APIs).

6. Practice container orchestration

Container platforms such as Docker are prevalent these days, mainly to implement microservices. They allow isolation, packaging, and easy deployment of microservices. They are also highly scalable and can be created on-demand. But what happens when you have to manage hundreds of containers and their numbers dynamically increase with the demand?

7. Use Infrastructure as Code

Infrastructure as Code (IaC) is used during various phases of DevOps to automate provisioning and management of infrastructure needed for a software release. This model generates the same environment every time it is applied and thus, helps in consistently creating repeatable infrastructure.

8. Have a security-first approach: DevSecOps

Security can never be overemphasized in scenarios where security breaches and vulnerabilities can lead to massive financial losses and damaged corporate reputation.

What is DevOps in business?

One of these newer approaches, aimed at further enabling business agility, is DevOps. This term resulted from the gap that arose from software development being built and packaged up by one group of people, and then being operated and maintained by a completely different group of people. The packages of software would metaphorically be thrown over the wall from the army of developers to the army of operational staff.

Why are information radiators useful?
