CircleCI vs Jenkins: Choosing The Right CI-CD Tool

So, What is Continuous Integration?

  • CircleCI: You can start using CircleCI for free. This is basically popular for GitHub projects and sports a self-hosted and a hosted solution.
  • Jenkins: An open-source platform that offers you ample versatility.
  • Pipelines: Launched by Microsoft this tool is free for up to 5 users.
  • Gitlab CI: A GitLab tool which can also be combined with several other tools through the API. It is available free of cost from Gitlab.

What is Continuous Delivery (CD)?

Key Points to Remember While Deploying With Continuous Delivery:

Deploy in smaller batches:

Delegate Responsibility:

Triggered Automation:

Continuous Delivery Tools

  • Azure Pipelines
  • Jenkins
  • Gitlab CI
  • GoCD
  • Spinnaker

What Made CI/CD Inevitable For DevOps & Agile Methodology?

Continuous Integration With CircleCI

  • Kubernetes
  • Microsoft Azure
  • AWS CodeDeploy, AWS EC2, AWS S3
  • Heroku
  • And other platforms by using SSH or configuring the API client.

Key features of CircleCI

  • It offers automated parallelism to speed up the deployment of multiple executions.
  • Quick set-up
  • Varied Customisation
  • It’s straightforward and easy to get started
  • Compact and quick to interpret setup of YAML
  • Does not require a dedicated server to operate CircleCI.
  • It caches application specifications and third-party configurations instead of system deployment.

Automating Builds With Jenkins

Key Jenkins features

  • Jenkins interacts with around all the SCM or constructs methods that currently exist.
  • Jenkins could be completely programmed from the helpful cloud Interface with robust on-the-fly bug tests and inline support.
  • In Jenkins some aspects could be expanded and updated, so it’s easy to set up fresh Jenkins extensions. This function helps you to tailor Jenkins for your requirements.
  • Jenkins is able to spread build / test loads to several machines of various platforms.
