This article will explain in detail how to understand the software supply chain of DevOps. The content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

In a broad sense, DevOps is a method based on lean and agile principles, which is used by business owners and development, operation and quality assurance departments to continuously deliver software, supporting enterprises to seize market opportunities faster and shorten the time it takes to integrate customer feedback.

Its overall life cycle is shown below:

And I think this life cycle can be called-- software supply chain.

The essence of DevOps

The essence of DevOps is extended collaboration among all stakeholders, not only between development and operations, but also between lines of business, suppliers involved in software delivery, and consumers themselves. In this extended sense, DevOps includes business governance practices on security and compliance, as well as all aspects of the delivery process, such as multi-source procurement. DevOps is an important enterprise function for continuous software delivery, enabling organizations to seize market opportunities and shorten customer feedback time.

DevOps methodology

The DevOps approach applies agile and lean thinking principles to all stakeholders in the organization, including customers and supplier partners. By extending Lean principles throughout the software supply chain, DevOps will accelerate customer feedback cycles, uniformly measure and collaborate across the enterprise, and increase productivity with less overhead, repetition, and rework. It provides a competitive advantage to the business through three dynamic functions:

Accelerate the continuous innovation of ideas by implementing collaborative development and testing throughout the value chain

Achieve continuous delivery of these innovations by automating the software delivery process and eliminating waste while helping to resolve regulatory issues

Provide feedback loops for continuous learning from customers by monitoring and optimizing software-driven innovation

Challenges facing DevOps

The value of DevOps can be described as an innovation and delivery cycle with a continuous feedback loop to understand and respond to customer needs. In order to realize the value of software-based innovation and delivery, some of the main challenges that enterprises must address in this key enterprise function are:

Until the enterprise actually delivers the software in a real production environment, what users may think is valuable is still unknown.

It will take at least 4 to 6 weeks to implement the change and deliver it to the customer

The larger the enterprise, the less collaboration between different groups (LOB, developers, operations, vendors, etc.), each using their own processes, tools, and infrastructure

Manual processes (not well documented) increase delays for all steps included in the process

Lack of metrics / metrics prevents the business from getting continuous feedback

Contradictory goals: the development team is driven by rapid change, while the operations team's

The driving force is to keep the environment stable.

Lean thinking and Agile methods adopted by DevOps

Eliminate any activities that are not necessary to understand customer needs, which emphasizes the use of a feedback loop to achieve fast, continuous iteration and customer insight.

Eliminate waiting times and delays caused by manual processes, as well as dependence on individuals.

Enable knowledge workers, business analysts, developers, testers, and other domain experts to focus on creative activities (not procedural activities), help maintain innovation, and avoid expensive and dangerous organizational and technological "relocations".

Turn to meaningful delivery analysis, optimize risk management, reduce uncertainty in a measurable way, and inspire proven learning.

What is needed for DevOps solution

Use a set of common practices based on lean thinking to maximize value through collaborative development and continuous testing (for continuous innovation) and eliminate any activities that do not directly benefit customers.

Automate manual and management activities (achieve continuous delivery), such as change and coordination, traceability, measurement, progress reporting, etc.

Establish a closed-loop feedback mechanism in a customer-oriented environment (to achieve continuous learning)

Use meaningful measurement and progress monitoring (for continuous optimization) to increase visibility across the organization, including the software value delivery supply chain.

How to understand the software supply chain of DevOps is shared here. I hope the above content can be helpful to everyone and learn more knowledge. If you think the article is good, you can share it for more people to see.
