Top 15 Best Continuous Delivery Tools in 2021 (A Complete List)

List and Comparison of the top Continuous Delivery Tools:

What is Continuous Delivery?

Continuous delivery is an approach of producing software in such a manner that the software can be readily/continuously released whenever required.

The entire activity is performed in a sequence of small repetitive cycles. This technique gives the provision to get any type of change incorporated (related to software enhancement, defect fixes, configuration change etc.) quickly in an efficient and sustainable way. 

We have compared the best Continuous Integration tools in our last tutorial. 

Top Continuous Delivery Tools

It enables the code to be in a deployable state, always & on demand. It diminishes the risk involved in delivering the changes as it uses the method of deployment in small repetitive incremental cycles and thus reducing the time & expense involved.

Logical concept of continuous delivery is quite similar to the Agile concept of delivery. It is closely related to Continuous Integration & DevOps as well. In other words, continuous delivery can be said as an extended version of agile and continuous integration methodologies.

Continuous Delivery is often confused with continuous deployment. Hence, it is extremely important to understand the difference between the two.

Difference between Continuous Deployment & Continuous Delivery

Continuous deployment means that all the changes go through a pipeline and are deployed in production automatically.

Whereas, continuous delivery gives the feasibility to a user to hold deployment if required, in a case of any specific business need. There is no automatic deployment in this case and team controls deployment.

The deployment pipeline is a set of validations, that code should flow through before it is released to production. Starting from a build, compiling, committing and testing using different testing techniques (manual/automated) prior to code release.

The toolset that might be opted by a team for continuous delivery depends on numerous factors. These factors include cost as a primary factor. Apart from these, client restrictions is another important factor to be considered.

Thus, one must first analyze particular need based on their requirement & ecosystem and pick the suitable type of tool accordingly.

Starting with small and eventually building up over a period of time is a better approach for sustainable continuous delivery.

This enables an organization to deliver incremental deliverables with quality and efficiency and yields a good return on the investment made on the tools used for continuous delivery.
