What is the difference between Ansible and Jenkins?

Ansible and Jenkins are both important in DevOps but serve different roles. Ansible is majorly employed for configuration management and automation of infrastructure tasks such as server setup and application deployment. Jenkins is actually a continuous integration and continuous delivery tool used to automate the software build, testing, and deployment pipeline. While Ansible manages the server and infrastructure setup, Jenkins manages the application lifecycle; thus, they are complementary tools in automating both infrastructure and deployment workflows.
