Top 2 Core Principles of DevOps: Automation and Quantification

DevOps (Development and Operations) is a collective term for a set of processes, methods, and systems that are used to promote communication, collaboration, and integration between development (application/software engineering), technical operations, and quality assurance (QA) departments. It emerged because the software industry increasingly recognized that in order to deliver software products and services on time, development and operations must work closely together. The author of this article briefly outlines the advantages of the DevOps concept and two principles: automation and quantification.

Introduction to DevOps
There is currently no unified standard definition for DevOps, which depends on the needs of each software or project. In short, DevOps refers to providing customers with efficient and technologically advanced services according to the specified requirements. At each stage or step of the system development life cycle (SDLC), you can choose any specified tool to provide customers with the best possible s solution.

DevOps is a perfect concept for developing and deploying efficient and high-quality software products. Today, in order to be able to deliver high-quality products to customers, basically every software product company uses DevOps more or less at a certain stage of the system development life cycle, including the concept of agile development, SCRUM (agile development), continuous integration And continuous delivery, etc., they can easily optimize software performance through DevOps. For any software development team, if software functions can be delivered in the shortest downtime, it will undoubtedly bring great happiness and satisfaction. Like other technical courses, DevOps can also learn AWS DevOps through offline or online training, and obtain a qualification certificate after passing a professional certification exam.

What can DevOps offer software companies?
For any organization, including software companies, customers are always the most valuable assets. Therefore, continuous customer satisfaction or customer care system (CCS) is critical for every company. If customers can quickly accept all the functional requirements they put forward, then they will have high satisfaction, and then become long-term satisfied customers of the organization or software company. The DevOps concept provides efficient and high-quality software development and deployment models, so it can also effectively support customer care systems (CCS).

DevOps can make the development quality higher, the development cycle shorter, the system more robust, the system security higher, and at the same time provide a more promising solution to the problem, so that customers can have high quality requirements within a specified time Project development. Since DevOps is a concept rather than a technology, there is no need to follow specific guidelines or specifications, and the development team can give full play to their flexibility and creativity during use. Many organizations adopt DevOps mainly to deliver high-quality products, which also spawns a large number of job opportunities. Learning advanced DevOps concepts provides better employment prospects for those who want to achieve success in the software industry, while No need to write code yet.

If you want to learn DevOps, you can join a research institution, which will provide you with practical guidance and on-site project training at the place you specify. After attending offline or online training, someone will guide you through the whole process to achieve your career goals. If it's an online mode, people who are highly motivated can save travel time, and then use this time to consolidate the concepts they have learned or prepare for the online DevOps qualification exam. According to the experience of senior DevOps community members, learning and using DevOps needs to follow the following principles:

1. Automation
In the past, manual operations were inefficient and inconsistent. Now, through DevOPs CI (Continuous Integration) and DevOPs CD (Continuous Delivery), automated operations can be achieved. All servers are automatically operated, so they can perform functional operations at the same time. Through software automation, software upgrades and security scanning processes are automated, and the quality assurance system can also be automated, but some manual interaction is still required.

2. Quantification
Many metrics are used in the DevOps pipeline, and different process metrics are also different, so users must know which process should use which metrics, and these metrics can also be used to measure and evaluate DevOps performance, for example, you must know software deployment How many bugs appeared in the process, and what impact will these bugs bring to users. There are many metrics that are used when monitoring the performance of business operations. For example, developers can measure the impact of their code on server performance and quantify this impact, so they are more clear about what improvements need to be made to achieve better performance.

The following are some key indicators common to all software when using DevOps:

System runtime
Production cycle
Mean repair time
Average discovery time
Deployment frequency
To sum up, DevOps can maximize software performance, enhance and optimize software functions compared to the software versions customers have used so far. Therefore, if someone wants to work in the software industry and wants to be perfect, he may wish to learn this unique and effective DevOps concept through professional training.
