Deployment for DevOps
2-day intensive bespoke advanced course
In the rapidly evolving world of software development and operations (DevOps), observability has become a cornerstone of ensuring application reliability, performance, and security. Observability allows teams to gain deep insights into their systems through the collection, analysis, and visualization of logs, metrics, and traces. It empowers developers and operators to identify and resolve issues swiftly, improving overall system robustness and user satisfaction. Complementing observability, Helm charts have revolutionized the deployment and management of Kubernetes applications, providing a standardized and efficient way to package, configure, and deploy complex applications in containerized environments.
This course aims to provide a comprehensive understanding of observability and Helm charts, equipping participants with the knowledge and skills needed to enhance their development and DevOps practices. Participants will learn log analysis, metrics visualization, tracing data analysis, and how to leverage Helm charts for effective application deployment. By the end of the course, attendees will be well-versed in modern observability techniques and proficient in using Helm charts to streamline Kubernetes deployments.
