Digital transformation refers to changing the way companies create value for customers by using modern technology and communication means. Nowadays, digital technology is being integrated into products, services, and processes to transform customers' business results and the delivery of commercial and public services. At present, almost all industries and companies are doing digital transformation, so how can we achieve digital transformation?
Generally speaking, digital transformation can be mainly divided into three aspects.
1. Process changes
Traditional waterfall development can no longer meet the demand of the market, and the iteration speed of applications has not kept up with the company’s requirements. In addition, the project delivery cycle is long. Once a step of the process is wrong, it will have a great impact on the whole project. Therefore, many application development teams have begun to switch from the waterfall development model to the agile development model. One of the important cores is rapid trial and error, which ensures development teams can improve their work in time.
2. Changes in organizational structure
The traditional IT architecture is like this: When a project is being built, a group of people is brought in a team to prepare for it. After the development is completed, the project is thrown to the Ops team. That means that the rest task is left to Ops teams when the project is completed. Whenever there is a problem with the application, there will be situations where responsibilities are evasive.
The agile transformation is mainly about the change of the development team, from a large team with a large number of people to a lean team, delivering applications in small steps and rapid iterations. At the same time, in order to meet their rapid iteration speed, the infrastructure team and some fast-delivered computing resources are also needed to meet this speed.
The transformation of DevOps has already undergone a fundamental transformation. The main thing is to change from Project to Product, and the main core of this change is to give the Product a life cycle. It means that this team can develop the products at the fastest speed, and iteratively updates on this basis. As long as the product exists, it will continue to update and iterate. At the same time, the infrastructure team will also set up a dedicated cloud platform team to build an IaaS or PaaS platform, standardize the underlying infrastructure, and integrate it into the CI/CD production line.
3. Changes in basic system architecture
The infrastructure began to be coded and standardized. Use code warehouse to iterate, keep the consistency of code warehouse and current network environment, and realize the source of the truth!
DevOps refers to a set of practices that emphasizes the collaboration and communication between software developers, operations, and maintenance personnel while automating software delivery and infrastructure iteration processes. It aims to establish a culture and environment in which software can be built, tested, and released quickly, frequently, and more reliably.
Continuous integration is a software development practice, that is, team development members often integrate their work. Generally speaking, each team member spends at least one day in integrating their work, which means that multiple integrations may occur every day. Each integration is verified through automated builds (including compilation, release, and automated testing), which ensures that integration errors can be found as early as possible.
Continuous delivery is a kind of software engineering method, which makes the output process of software products complete in a short period, so as to ensure that the software can be stably and continuously released at any time. Its goal is to make software build, test, and release faster and more frequently. In this way, network engineers can reduce the cost and time of software development and reduce the risk of the project.
Continuous deployment means that all changes are automatically deployed to the production environment, but for business reasons, you can choose not to deploy. If continuous deployment is to be implemented, continuous delivery must be implemented first. Many people will equate digital transformation, DevOps, agile, CI / CD, but in fact, they are all essentially different.
As developers increasingly bypass internal IT teams to meet business demands for speed, cloud, automated deployment, and DevOps practices are reshaping IT. Network operation and maintenance personnel are learning how to apply their expertise in new ways to build an independent infrastructure self-service platform for the development team. F5 proposed the concept of super Netops, the main purpose of which is to hope that network operation and maintenance personnel can provide services through an automated toolchain, shorten the service time from a few days to a few minutes. Through the learning of these skills, network operation and maintenance personnel can master automation skills in all aspects of operation and maintenance applications, and then they can operate and maintain other infrastructure equipment with ease.
