Continuous Integration, or CI, is an automated process that merges and tests all the code changes developers make to a repository. Multiple developers can systematically contribute code, and the resulting codebase can be integrated and automatically tested to avoid regressions and breaking changes.
With CI, Changes are tested and integrated into the project as the code bases change and new code is added.
Without CI: Without a continuous integration process, code changes need to be manually integrated into the main codebase, and testing needs to be manually triggered or executed by developers or system administrators.
With a manual approach, it's left up to the person integrating the code and testing the resulting codebase to make a judgment call about whether it is ready for production.
This manual process requires intense coordination among teams, and the integrators and testers can quickly become bottlenecks in integrating updated code and new features into the main codebase. This means that timelines are significantly slowed down, and updates, changes, and improvements may not make it to market for a while.
By adopting a continuous integration approach and investing in automated testing, code changes and new features can be integrated into your project the whole time (or continuously), often without a schedule.
In its most elegant and optimal configuration, a Continuous Integration process will flow smoothly into a Continuous Delivery process.
Continuous Delivery, or CD, follows a CI process to build, test the build, and "deliver" the built software to a production-ready state quickly and frequently.
Adopting a Continuous Delivery approach enables teams to deliver updates on their chosen timeline (usually as fast as possible). CD eliminates the need for scheduling teams to integrate the code and features into a production-ready state.
This is because CD ensures fixes and improvements in the latest build will be tested, stable, and production-ready when the release manager or person in charge of deployment deploys the build. This way, developers don't have to worry about those tasks so that they can do literally anything else.
With CD: Developers can respond to requests from leadership and end users quickly, deploying new solutions, features, and fixes to production-ready states rapidly. Visibility and communication are improved, and developers can deliver new application builds with fewer constraints. Automated testing ensures that no bugs or errors make it to production.
Without CD: Delivering working builds of patched, updated, and extended applications can take much longer when done manually. This can delay new solutions, innovation, and results that leadership wants, and end users will likely be frustrated and waiting around.
At the core, Continuous Delivery is all about enabling agile teams to deliver verified working software quickly and constantly in a predictable, testable way. Continuous integration facilitates continuous delivery, which has a significant business impact on developer teams and enterprises.
As you can imagine, this gives them a substantial leg up.
Actually, yes—confusingly, CD refers to Continuous Delivery and Continuous Deployment, also known as "The Other CD."
The two are similar, with one key difference.
With continuous delivery, a Release Manager or engineer will manually trigger a build's deployment to production. Teams can choose when to take this manual step and take steps to initiate the deployment. This is the more "hands-on" approach, and it's left to the team's discretion.
Continuous deployment, however, doesn't require people or humans to take this manual step. It's fully automated, so developers don't need to stop everything to trigger this process. It will happen automatically. It doesn't make sense for all projects to deploy automatically, but it can be very effective for those that need to.
CI/CD work together to help developers get things done quickly and support business goals driven by marketing and development teams. CI and CD both help ensure that new code, features, and patches are continuously integrated into production-ready software and can be pushed out quickly by Release Managers or Engineers or even deployed automatically.
The CI/CD process improves site and app hosting in several ways. Regarding CI/CD, the game's name is speed and efficiency, which is ideal for web teams—there's no time to waste.
Any changes you make to a site with CI/CD methodology are instantly available to users because of the medium - typically a web browser or app. Since there's no "download and install" phase, as there might be for other types of software, users can expect rapid updates and quick changes, and web teams can thoroughly test before releasing.
CI/CD helps your team keep projects moving, making it easier to launch new sites, make updates, and integrate new code quickly. This leads to improved customer experience, as end users will get new and improved features and big fixes faster than before.
Since continuous deployment automatically releases code to production, developers don’t have to drop everything for releases anymore - it quickly becomes a regular part of their day. With CI/CD, almost no manual intervention is required, especially when combined with tools and systems like Kubernetes and Lagoon.
This means that updates, changes, and new features can be released quickly and without hassle on your sites and apps.
Technically, yes. CI/CD methodologies can form an additional critical layer of security: defense against the unexpected. With CI/CD, since everything is so rigorously tested, anything being deployed is a known entity - and less likely to expose you to security holes. If code contains errors, inconsistencies, or holes that could make your team more vulnerable, the CI/CD processes will flag warnings to notify you before it’s released to production.
CI/CD can also make overseeing a large fleet of sites much more manageable. When you have multiple sites, it is essential to ensure they are structured and built similarly. It would be nearly impossible to manually manage and oversee 400 sites that were all built incredibly differently. CI/CD’s repeatability can help ensure all sites have baseline features similar to the relevant sites’ code base.
Since CI/CD are essential components of any good WebOps model, amazee.io’s platform offers continuous integration, delivery, and deployment so you can deliver and deploy your product to customers - your way.
Our CI/CD model ensures speedy, safe, and repeatable workflows every single time so your team, your business, and your end users can have what they want when they want it.
Our CI/CD processes ensure that by the time your code is deployed to Lagoon, it’s been checked and balanced: The code base functionally works and has also passed all the other governance-based checks. Once your code is deployed, you have nothing to worry about. Lagoon also works with multiple CI/CD systems, so we don’t have to use just one.
In addition to CI/CD workflows and managed Kubernetes expertise, amazee.io’s platform guarantees uptime with 24/7 monitoring and support, along with globally managed CDN + advanced WAF. CDN + WAF boosts your site’s performance with complete security and optimization. These are all crucial components of a functional WebOps platform, which maximizes developer productivity by providing the tooling they need to focus on core work.
