AI Tactical Skills:  

Build and Secure Kubernetes using Practical Skills 

In this 5 day course, you will gain the practical skills needed to fully understand Kubernetes.

 

We will explore Kubernetes concepts and system architecture, the challenges it addresses, and its model for managing containerized deployments and scaling. You will learn critical concepts such as clustering, scaling, extending, and securing Kubernetes.

 

Additionally, we will cover essential topics like monitoring and troubleshooting deployments and installations across various environments, including local, on-premise, cloud, and multi-cloud scenarios.

 

Finally, we will discuss long-term strategies for supporting and maintaining Kubernetes solutions, ensuring you are well-prepared for ongoing management and optimization.
