Course Introduction

Welcome to the Service Mesh with Istio course!

I'm Sevi Karaköse, your instructor for this journey. With extensive experience as a software developer, team leader, and technical trainer, I have partnered with both development and infrastructure teams during DevOps transformations. My focus has involved transforming legacy applications into microservices and modernizing cloud environments. In this course, we’ll explore Istio through detailed lectures and hands-on labs.

Getting Started

To begin, we'll set up the necessary environment and tools for working with Istio and Kubernetes. This preparation ensures you're ready for the hands-on labs and demonstrations ahead.

Course Structure

We start with Istio fundamentals and gradually introduce more advanced concepts. Throughout the course, you'll engage with practical examples and labs that reinforce the material.

Course Objectives

As we progress through the course, we will cover the following topics:

1. Introduction to Istio
   We start by distinguishing between monolithic and microservices architectures and discussing the critical need for a Service Mesh. Example-driven lectures will help you understand these concepts in depth.

2. Getting Started with Istio
   You'll learn how to install and configure Istio, and how to visualize your applications using Kiali.

3. Deep Dive into Istio Concepts
   We will explore advanced features of Istio, including Gateways and Virtual Services, Destination Rules and subsets, timeouts and retries, circuit breaking, fault injection, and traffic management strategies such as A/B testing.

4. Security and Observability
   Learn about certificate management, authentication, and authorization. Additionally, you'll discover how to collect metrics using Prometheus and Grafana, and how to implement distributed tracing for your services.

5. Kubernetes Fundamentals
   A brief review of essential Kubernetes concepts ensures you have the background needed as we integrate Kubernetes with Istio.

I am excited to guide you through the world of Service Mesh with Istio. Let’s begin this engaging learning experience and dive into the practical aspects of managing microservices effectively!
