Professionals learn how to implement "Security as Code" and ensure that no insecure artifacts reach production. This involves using Jenkins to orchestrate tools for static and dynamic analysis.
SRE Path
For SREs, Jenkins is used to automate operational tasks and ensure system reliability through automated testing and canary deployments. This path focuses on the scalability of Jenkins itself and how to use it to maintain high availability. It bridges the gap between software engineering and IT operations.
AIOps Path
This specialized track explores how to use machine learning data to trigger or optimize Jenkins workflows. It involves integrating AI-driven insights into the pipeline to predict failures or optimize resource allocation. Professionals here focus on making the automation server smarter and more self-healing.
MLOps Path
The MLOps path uses Jenkins to automate the training and deployment of machine learning models. It covers the unique challenges of data versioning and model monitoring within a continuous delivery framework. This is essential for teams looking to scale their data science operations.
DataOps Path
DataOps focuses on automating data pipelines to improve the quality and cycle time of data analytics.
