I.       Overview:

This two-day instructor-led course prepares students to modernize, manage, and observe their applications using Kubernetes whether the application is deployed on-premises or on Google Cloud Platform (GCP). Through presentations, and hands-on labs, participants explore and deploy using Kubernetes Engine (GKE), GKE Connect, Istio service mesh and Anthos Config Management capabilities that enable operators to work with modern applications even when split among multiple clusters hosted by multiple providers, or on-premises.

II.     Duration: 02 days

III. Objectives

• Connect and manage Anthos GKE clusters from GCP Console whether clusters are part of Anthos on Google Cloud or Anthos deployed on VMware.
• Understand how service mesh proxies are installed, configured and managed.
• Configure centralized logging, monitoring, tracing, and service visualizations wherever the Anthos GKE clusters are hosted.
• Understand and configure fine-grained traffic management.
• Use service mesh security features for service-service authentication, user authentication, and policy-based service authorization.
• Install a multi-service application spanning multiple clusters in a hybrid environment. Understand how services communicate across clusters.
• Migrate services between clusters.
• Install Anthos Config Management, use it to enforce policies, and explain how it can be used across multiple clusters.

IV. Intended Audience

This class is primarily intended for the following participants: Technical employees using GCP, including customer companies, partners and system integrators: deployment engineers, cloud architects, cloud administrators, system engineers , and SysOps/DevOps engineers. Individuals using GCP to create, integrate, or modernize solutions using secure, scalable microservices architectures in hybrid environments.

V.    Prerequisites
