What is a continuous delivery?

Continuous delivery (CD) is described as the capacity to offer product updates to clients as quickly and frequently as feasible.

Continuous delivery is also known as “continuous integration.” Whether these updates consist of minor bug patches, enhanced functionality, or a completely redesigned interface, Continuous delivery describes the overarching process and protocols that you must follow to get code into production as quickly as feasible.

The History of Continuous Delivery

For a long time after the area of software development was established, many teams depended on a waterfall methodology to manage their software development life cycle (SDLC).

This began to change in the 1990s due to agile software development approaches, which enabled teams to ship small and frequent updates rather than constructing a complete product from the ground up.

Given their flexibility in making changes on an incremental basis, new frameworks based on agile principles quickly became the de facto standard for many organizations. Frameworks such as continuous delivery, DevOps, and continuous deployment were incorporated, and these approaches have since gained popularity, reaching a new level of prominence.

Even though all of these concepts fall under the tent of agile frameworks, some significant distinctions and implications distinguish them from one another. The purpose of this article is to provide an

The Pros And Cons of Continuous Delivery

Product teams reap numerous benefits from the use of continuous delivery practices.

One of the most noticeable advantages is the frequency with which feedback loops occur.

Customers will have a new opportunity to provide feedback for every new update sent to them by you. This translates into more frequent windows for essential insights every time you deploy a new update to your customers. Continuous delivery helps to reduce risk in this way.

There is always a degree of uncertainty in the software development process when working on new initiatives.

Because product development is a time-consuming and expensive process, concepts must be validated as early in the process as possible. Continuous delivery can make this a possibility because of the increasing number of feedback loops.

Increasingly, businesses are adopting a culture of continuous delivery as part of their overall mindset. It is no longer a competitive advantage but rather a need to remain above the fray in today’s world.

The purpose of Continuous Delivery

A primary goal of continuous delivery is to provide a painless deployment procedure that is low-risk by nature and can be completed in a largely automated fashion.

Many software teams do this by using a technique known as “zero-downtime deployment,” which allows consumers to be completely oblivious that upgrades have been performed. The benefit of doing so is that firms can iterate and develop their products in a non-intrusive manner, resulting in increased user retention.

Continuous Delivery vs. Continuous deployment

First, you need to Understand that continuous delivery is not the same process as continuous deployment, which is key to success.  Although these two terms are sometimes used interchangeably, they serve fundamentally different functions in the software development lifecycle (SDLC).

The following is an explanation of how these two processes are related to one another:

The term “continuous deployment” refers to the automatic implementation of modifications regularly. This usually is accomplished through a series of daily updates.

Constantly deploying software updates is defined as having the ability to do so regularly, which is required to perform continuous deployment. It is more of a state of mind and a way of life than a specific discipline. This delivery method has its specified framework, though it may differ depending on the company and the product being delivered.

The following are necessary procedures often included in continuous delivery: planning changes, developing these updates, testing, code merging, retesting, pushing live, and validation.

Many software teams are working hard to keep the majority of this process automated and easily reproducible to speed up the process as much as possible.

Tips for a better Continuous Delivery

Get your product to market as soon as possible

Teams may automate a large portion of the deployment process, including regression and environmental testing, by utilizing continuous delivery.

Teams can send goods to market considerably more quickly if they are given the ability to omit these phases from their everyday tasks (and iteratively).

You should produce higher-quality products

It is possible to detect and correct issues more rapidly with continuous delivery, allowing teams to grasp essential usability needs better. Thus encouraging a more user-centric mindset, which leads to an overall improvement in the quality of the final product, is further enhanced.

Boost the morale of your squad

Continuous delivery encourages a culture of sending updates more frequently and in smaller batches than traditional delivery methods. This helps your team prevent burnout while also continuously providing a higher sense of progress for everyone on the team.

Because of the promoted mindset, software engineers are more engaged with end-users, which motivates them to produce high-quality deliverables that consumers will like using.

The components of Continuous Delivery

As mentioned before in the history section of this article, Jez Humble, an award-winning author, established five fundamental criteria for implementing a successful continuous delivery approach.  In his book (Continuous Delivery: Reliable Software Releases Through Build, Test, and Deployment Automation), he proposes that software developers adopt the following five guidelines:

• It is necessary to incorporate quality into production procedures.
• You should keep batch sizes for development and release to a minimum.
• People should be problem solvers, and you should entrust machines with repetitive tasks.
• The pursuit of continuous improvement should be a continual objective.
• Everyone is responsible for their actions.

The Agile Manifesto has several ideas that are similar to those listed above. This also demonstrates how continuous delivery is an adaptation of agile, as well as the ideals that are associated with it.

Conclusion

We can see from continuous delivery that frequent software deployment does not harm the stability or reliability of our software systems. On the contrary, it has provided firms worldwide with a distinct competitive advantage.
