Developers write unit tests to individually check the functioning of each smallest testable software part early in the development stage. 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. Previously, the security of a solution was taken care of only upon development completion. With DevOps, security is integrated into the very principles of a software piece from its inception, which ushered the notion of DevSecOps.
Their work is a must-read for anyone who’s trying to figure out which DevOps structure is best for their company. The right DevOps team will serve as the backbone of the entire effort and will model what success looks like to the rest of the organization. There is no “one size fits all” however – each team will be different depending on needs and resources.
Development and operations collaboration
Properly embracing DevOps entails a cultural change where teams have new structures, new management principles, and adopt certain technology tools. Despite a large amount of info on DevOps, there’s still a lack of details on concrete steps to take to start DevOps implementation and make it successful to speed up software development and operations. DevOps is an approach to working that emphasizes the quick, incremental, and continuous delivery of products.
Get ideas from the experts’ advice below, and formulate a plan to introduce everyone to DevOps, get them excited about it and ensure ongoing communication. Smart hiring tactics establish the right DevOps team structure, as well as an understanding of everyone’s roles. Place a high value on learning and collaboration, beyond simply designating teams, and this shrewd composition of skills can start a revolution in how IT works. When software is put into containers, the containerized application needs to be managed properly. Such infrastructure automation tools as Kubernetes, Ansible, Chef, or Puppet are integrated with CI/CD tools like Jenkins, Bamboo, or GoCD for more efficient configuration management and software deployment. System administrators spend days or even weeks to prepare a new development, testing and production infrastructure for a new project.
DevOps Team Structure and Best Practice
Continuous Integration and Continuous Deployment (CI/CD) sits at the heart of DevOps. This pipeline comprises integrated processes required to automate build, test, and deployment. In the Build phase, a compilation of the application takes place using a version control system.
Most importantly, commitment and buy-in from every member are also important. In a traditional waterfall software development environment, different teams are assigned different tasks. Developers are focused on introducing features according to project requirements using existing software, while the operations teams are concerned about the stability of the infrastructure.

It is their responsibility to design and run tests that assess whether each new release meets those requirements as it flows through the CI/CD pipeline. Whether it’s with two pizzas in a conference room or the adoption of real-time collaboration tools and easily updated documentation, organizations must make an effort to bring DevOps teams together. The particular activities and tasks will vary, depending on the existing corporate culture, proximity to like-minded IT folks and leadership.
Security, network, and data center management teams usually sit together on this task to prepare a cloud migration framework with well-written documentation. At this stage, a cross-functional DevOps team is formed with members from IT, operations, security, finance, and management that share the common responsibilities of DevOps to implement the cloud migration framework. It is vital for every member of the organization to have access to the data they need to do their job as effectively and quickly as possible. Team members need to be alerted of failures in the deployment pipeline — whether systemic or due to failed tests — and receive timely updates on the health and performance of applications running in production.
The increased amount of test automation
This is one of the top DevOps Trends teams should follow; read the full blog to learn more. When you migrate from AWS to Azure or GCP, you might have to realign the software. Multi-cloud platforms are more complex and require high expertise, skill sets, and a proper strategy to make a smooth transition. Here’s a great blog about Microservices vs Monolith that can help you understand the differences between them. Because of the continuous nature of DevOps, practitioners use the infinity loop to show how the phases of the DevOps lifecycle relate to each other.
While one on-call engineer responds to incidents, DevOps teams assign multiple people for escalations so that the on-call engineer can escalate it to the right person or team. Once the issue is cloud operations team structure resolved, teams analyze the system again to get prepared for future incidents. An enabling team composed of specialists in a given technical (or product) domain help bridge this capability gap.
key organizational models for DevOps teams
As development gets faster in DevOps, QA needs to match this pace to run automated tests. QA being dependent on CI, continuous monitoring becomes an integral part of every stage of the product life cycle. The current monitoring tools are not just confined to production environments but they also proactively monitor the entire app stack. When monitoring is integrated into the DevOps lifecycle, tracking DevOps KPIs becomes easy, and app deployments become efficient. It also facilitates seamless collaboration between development and operations teams.
- They have to work on sharing their knowledge and their lessons learned.
- To convince business users of high software quality, it’s important to establish strong communication with them.
- Is your team quick to change direction based on feedback (customer or internal) from the latest changes?
- Over the long term, cracks start to appear, spreading from the blind spots into areas the team initially did well.
- As the core responsibility of the team would be on the person who owns the DevOps team, a senior person from the organization would be an ideal person to lead the team, referred to as a DevOps Evangelist.
You may decide your organization just doesn’t have the internal expertise or resources to create your own DevOps initiative, so you should hire an outside firm or consultancy to get started. This DevOps-as-a-service (DaaS) model is especially helpful for small companies with limited in-house IT skills. In this model, a single team has shared goals with no separate functions.

While Ian Buchanan has broad and deep experience with both Java and .NET, he is best known as a champion of lean and agile practices in large enterprises. Mature teams release multiple times per week, and in some cases, multiple times per day. In pursuit of this goal, mature teams should use continuous integration and continuous delivery (CI/CD) to ship features frequently. Here at Atlassian, platform teams build services used by all of our products (like identity management) and are expected to provide documentation, support, and consultation for stream-aligned teams.
System hardening is another security process that strengthens the system configuration and reduces potential vulnerabilities. By removing unnecessary programs, accessible accounts, you can reduce threats. Customizing security rules above or beyond regular configurations is required.
Using Spinnaker with Kubernetes for Continuous Delivery
After assembling the necessary resources for the DevOps team structure, organizations must avoid jumping into implementing DevOps practices. This means that the business requirements of the organization and the overall company vision must correspond with the objectives of the DevOps team. Technology advances from multicloud to microservices and containers also play a role when it comes to defining the right DevOps team structure. In our 2020 Global DevSecOps Survey, 83% of respondents said their teams are releasing code more quickly but they also told us their roles were changing, dramatically in some cases.
