DevOps maturity model is all about implementing the DevOps culture and the use of required automation tools in order to Improve the collaboration among various teams from planning through product delivery and automation of the delivery process. The following are the goals of DevOps culture that could be achieved with the use of various DevOps tools list.
- Improve deployment frequency: The use of DevOps tools helps to create a CICD pipeline where the building of the application code, running of the automated test cases, and the deployment takes place in the sequence without any human intervention. Each of the steps in the workflow provides the transparency through the logs and progress bar.
- Achieve faster time to market: Use of the automation tools and integration of these tools with other testing and deployment tools together orchestrate and speed up the product development that ultimately reduces the time to deliver the software to the market.
- The lower failure rate of new releases: The modern automation tools have equipped to provide the complete insight of the application health, and visual logs representation depicting the code deployment or build failure or success. It reduces the rate of product failure of the new releases as tools are very good in tracking the flaws in the release over releases.
- Shorten the lead time between fixes: The use of automation tools and the integration of these tools to form a product delivery pipeline reduces the lead time between the product fixes.
- Improve mean time to recovery: DevOps culture and automation tools together help to improve mean time to recovery from failures.
There is an endless list of tools that can get used together to orchestrate the continuous integration, continuous deployment, and continuous delivery but, anyone needs to make to wise choice depending on the tools suitability, tools knowledge, and the scope of the organization projects utility. All tools are not compatible with each other. Therefore, the selection of the compatible tools is very important before any organization can think to implement the DevOps solution.
Key DevOps tools list and practices are as follows.
1) Source Code Repository:
A source code repository is a centralized repository where developers continuously check-in and check out code. The source code repository should be capable to manage the various code versions that are checked in so that developers do not overwrite each other’s work. It should maintain the author’s details, date, and time details for each version of the code. It should be capable to compare the code versions and outline the changes made in the code. It forms a major component of continuous integration as this is where the code is present that can be checked out for build and integration. The following are the popular source code repository tools.
- Git
- Subversion
- Cloudforce
- Bitbucket
- TFS
2) Build Server:
It is an automation tool where the code gets compiled after being checked out of the source code repository into the executable code base. The following are the popular build tools.
- Jenkins
- SonarQube
- Artifactory
3) Configuration Management:
It defines the server or an environment configuration. The following are the popular configuration management tools.
- Puppet
- Chef
4) Virtual Infrastructure:
AWS (Amazon Web Services), and Microsoft Azure are the best examples of virtual infrastructures. They are provided by the cloud vendors which sell infrastructure or platform as a service (PaaS). They have APIs that allow to programmatically create new machines with the help of the configuration management tools such as Chef and Puppet. They are also available in the form of private clouds such as VMware, and vCloud. Such virtual infrastructures enable us to execute a cloud on top of the hardware in the data center. Virtual infrastructures can be easily combined with automation tools which can empower the organizations practicing DevOps with the capability to configure a server without any manual interventions. We can easily test our brand-new code automatically by sending it to our combined cloud infrastructure followed by building the environment and run all of the tests without any human intervention.
5) Test Automation:
DevOps testing is completely focused on the automated testing within the build pipeline to ensure that the deployable build has passed the necessary tests, and it is ready to be deployed. Test automation makes us very confident about the recent build to get deployed on production without any human intervention. The following are popular tools.
- Selenium
- Water
6) Pipeline Orchestration:
It can be visualized as a manufacturing assembly line where the code checked-in by the developer gets build by the build tool and tested with the help of the automation tool. Further, the tested code gets deployed into production via deployment tool and made available to the limited set of users initially followed by the full set of developers based on the feedback from the initial set of users.
7) Unified Enterprise Software Development and Delivery:
VersionOne® Continuum™ is an enterprise continuous delivery solution that can automate, orchestrate, and visualize the flow of change throughout the software delivery cycle. We have already discussed DevOps Continuum in detail in the previous chapter.
