Jenkins

1. Suited well for a company which has more than 10 apps to deploy. 2. Not suited for a place where Serverless or Event-Driven CI/CD with Minimal Setup is required.
3. If project requires fine-tuned control over build steps, conditional deployment flows, and script-heavy automation, Jenkins provides unmatched flexibility using Jenkins file and Groovy scripting.

Centralized pipeline management using shared libraries and templates. Multi-branch pipelines for handling parallel feature development. Send notifications to Slack, Teams, email, or enterprise dashboards. Integrate with SonarQube, JIRA, Prometheus, and others for metrics and tracking. Produce detailed test and deployment reports—Ross's large dev teams.

Its' a good for continuous deployment, continuous integration, and continuous delivery also it's the best integration tools in the market. It also supports many plugins and it is targeting users are developers and teams looking to automate parts of their software development
process. If number of jobs are more this won't be that great application.

Jenkins is suitable to implement for small organizations as it uses single server architecture. It can be used to automate deployments and script execution which helps users automate manual tasks. Jenkins is opensource and has a strong community which helps in resolving errors. Jenkins might not be suitable for large organizations or complex architectures. There are other competitors which might have an edge like Atlassian Bamboo/Octopus.

I think Jenkins is well suited if you are using a lot of build minutes and have to use your own hardware. It is also well suited if you need to customize your build and deploy process quite much, which is very possible with Jenkins. If your build and deploy needs are rather straight forward, it might be easier to just get a cloud service that provide you with easier to use interface and processes.
