The ABCs of CI/CD: What is it and Why Do We Need It?

CI/CD, or Continuous Integration and Continuous Delivery, is a methodology for delivering software. It focuses on automating the process of designing and building code to be released sooner and with less risk. CI/CD uses automation to provide visibility into how changes in one part of the system affect other parts, reducing errors and improving productivity. Many companies have embraced it as a vital tool for their It jobs. According to statistics from Jobtensor Continous Integration belongs to the Top10 IT Skills as of October 2021.

Continuous Integration (CI) is the practice of integrating all parts of a system frequently – typically each time something changes. For instance, if you are working on an app for Android devices, your CI server can be configured to build updates when new code is submitted so that developers don’t have to wait until they feel like building their version before testing out whether there were any problems with their latest update or not. This way, bugs in the mobile apps will get found early, which speeds up development by allowing errors to be dealt with quickly instead of waiting until late stages in software release cycles were fixing them would take much longer than necessary due to frequent deployment schedules being missed because major issues were found too late in the development process.

Continuous Delivery (CD) is a practice of releasing updates to an application or service as they are completed instead of saving them up for big batches that only come out now and then, creating problems with customer satisfaction due to long wait times between changes being made by developers and those same changes appearing on end-user devices. Using CI/CD makes it possible for applications to be released more frequently because their quality will have been improved through regular testing throughout software development cycles – this means faster time-to-market when new features need to go online quickly after being implemented. Continuous delivery can also make deployments less risky if done correctly since there is no longer any need to wait until all stages of deployment are complete – automated tests can be run with each commit to making sure that any new features are working as intended before they get released.

For Continuous Deployment (CD) or Delivery (CD) to work correctly, there must always be at least one stage configured so that failing automated tests get flagged up before going any further. If no such stage exists, then the only way to know that something is wrong would be after all stages of deployment were completed.

CI/CD improves software development by:
-Reducing risk associated with new deployments or updates because all tests have been run against every iteration before being released; if something does happen, then repercussions are limited since only a small number of users were impacted rather than everyone.
-Enabling reliable and repeatable deployments with a complete history of changes made available; if there was a problem in the past, it can be easily identified and rolled back with minimal impact on users.
-Improving the speed of releases by running automated tests continuously; when new code is committed to version control, builds are created automatically so that developers always know what’s going on without having to wait for someone else to put together a new release or manually run any tests themselves.

CI/CD helps companies by:
-“Become more agile” because they can quickly respond to changes made by competitors since the software can be updated immediately instead of waiting weeks until finished and tested (which is how things were done before CI). With every build being released as soon as possible after passing automated tests means you’re essentially “racing ahead” of future changes and always staying up to date with the latest software your customers want.
-Improve customer satisfaction by allowing them access to new features or bug fixes promptly instead of waiting for release dates that might never happen since development has ground to a halt due to lack of resources, management issues, etc.

-CI/CD can help companies become more transparent because they are no longer hiding behind closed doors but sharing what’s going on when something is happening – this level of transparency helps keep everyone informed, so nothing gets missed even if not all information is shared is positive which means people will have an accurate understanding about where things stand rather than wondering why there haven’t been any updates lately without knowing whether it was intentional or caused by some unforeseen issue.
CI/CD allows companies to be flexible because they can quickly adjust their processes, infrastructure, and software to meet the demands of customers who are always looking for something new or different – this means you won’t have any trouble staying ahead of your competition, on IT jobs, which is essential in today’s market where there are more options than ever before thanks to cloud computing making it possible for anyone with an Internet connection (and credit card) to start a website business overnight without having any technical knowledge required.
