Jenkins vs TeamCity: What are the differences?
Both Jenkins and TeamCity are continuous integration tools that serve many of the same purposes. Jenkins is an open source tool, while TeamCity is a proprietary offering from JetBrains. Jenkins is older than TeamCity, so it has a larger community and wider use in general; it appears in far more stacks than its competitor. TeamCity is considered by users to be easier to configure and more straightforward to use, while Jenkins is appreciated for its rich set of plugins and integrations.
We are currently using Azure Pipelines for continous integration. Our applications are developed witn .NET framework. But when we look at the online Jenkins is the most widely used tool for continous integration. Can you please give me the advice which one is best to use for my case Azure pipeline or jenkins.
I'm open to anything. just want something that break less and doesn't need me to pay for it, and can be hosted on Docker. our scripting language is powershell core. so it's better to support it. also we are building dotnet core in our pipeline, so if they have anything related that helps with the CI would be nice.
I'm planning to setup complete CD-CD setup for spark and python application which we are going to deploy in aws lambda and EMR Cluster. Which tool would be best one to choose. Since my company is trying to adopt to concourse i would like to understand what are the lack of capabilities concourse have . Thanks in advance !
I would definetly recommend Concourse to you, as it is one of the most advanced modern methods of making CI/CD while Jenkins is an old monolithic dinosaur. Concourse itself is cloudnative and containerbased which helps you to build simple, high-performance and scalable CI/CD pipelines. In my opinion, the only lack of skills you have with Concourse is your own knowledge of how to build pipelines and automate things. Technincally there is no lack, i would even say you can extend it way more easily. But as a Con it is more easy to interact with Jenkins if you are only used to UIs. Concourse needs someone which is capable of using CLIs.
We replaced Jenkins with Github Actions for all our repositories hosted on Github. GA has two significant benefits for us compared to an external build tool: it's simpler, and it sits at eye level.
Its simplicity and smooth user experience makes it easier for all developers to adopt, giving them more autonomy.
Sitting at eye level means it's completely run and configured right alongside the code, so that it's easier to observe and adjust our builds as we go.
These two benefits have made "the build" less of a system engineer responsibility and more of a developer tool, giving developers more ownership from code to release.
Jenkins is a friend of mine. 😀
There are not much space for Jenkins competitors for now from my point of view. With declarative pipelines now in place, its super easy to maintain them and create new ones(altho I prefer scripted still). Self-hosted, free, huge community makes it the top choice so honestly for me it was an easy pick.
Within our deployment pipeline, we have a need to deploy to multiple customer environments, and manage secrets specifically in a way that integrates well with AWS, Kubernetes Secrets, Terraform and our pipelines ourselves.
Jenkins offered us the ability to choose one of a number of credentials/secrets management approaches, and models secrets as a more dynamic concept that GitHub Actions provided.
Additionally, we are operating Jenkins within our development Kubernetes cluster as a kind of system-wide orchestrator, allowing us to use Kubernetes pods as build agents, avoiding the ongoing direct costs associated with GitHub Actions minutes / per-user pricing. Obviously as a consequence we take on the indirect costs of maintain Jenkins itself, patching it, upgrading etc. However our experience with managing Jenkins via Kubernetes and declarative Jenkins configuration has led us to believe that this cost is small, particularly as the majority of actual building and testing is handled inside docker containers and Kubernetes, alleviating the need for less supported plugins that may make Jenkins administration more difficult.

TeamCity is our main continuous integration server. It starts creating builds and running tests based on commits that we make in our hosted bitbucket repositories. From there, we have a set of configuraitons that can deploy the built and tested artifacts (web app, batches, db, etc...) to a stage or production server. We still release manually, but we release often, and TeamCity has nice features to help us roll back when things don't work out as planned.
TeamCity builds then copies to each web tier via a powershell script. The steps for each server are:
- Tell HAProxy to take the server out of rotation via a POST
- Delay to let IIS finish current requests (~5 sec)
- Stop the website (via the same PSSession for all the following)
- Robocopy files
- Start the website
- Re-enable in HAProxy via another POST
All of our pull requests are automatically tested using Jenkins' integration with GitHub, and we provision and deploy our servers using Jenkins' interface. This is integrated with HipChat, immediately notifying us if anything goes wrong with a deployment.
Jenkins is our go-to devops automation tool. We use it for automated test builds, all the way up to server updates and deploys. It really helps maintain our homegrown continuous-integration suite. It even does our blue/green deploys.
- Continuous Deploy
- Dev stage: autodeploy by trigger push request from 'develop' branch of Gitlab
- Staging and production stages: Build and rollback quicly with Ansistrano playbook
- Sending messages of job results to Chatwork.
Currently serves as the location that our QA team builds various automated testing jobs.
At one point we were using it for builds, but we ended up migrating away from them to Code Pipelines.
We use Jenkins to schedule our Browser and API Based regression and acceptance tests on a regular bases. We use additionally to Jenkins GitlabCI for unit and component testing.
I'm using a selfhosted TC as Referenceplatform, and use travis with another configuration.
