**Key Features of Istio in Distributed Systems:** 🚀
– **Service Discovery**: Easily find and connect to services, no more searching for the proverbial needle in the haystack!
– **Automatic Load Balancing**: Distribute traffic intelligently and efficiently without manual intervention.
– **Routing, Circuit Breaking, Retries, Fail-overs, Fault Injection**: Manage traffic dynamically to ensure resilience and reliability.
– **Policy Enforcement**: Implement access control, rate limiting, A/B testing, traffic splitting, and quotas to govern service interactions.
– **Metrics, Logs, and Traces**: Gain insight into your services with comprehensive monitoring capabilities.
– **Secure Communication**: Encrypt data in transit within the cluster for enhanced security.
– **Authentication and Authorization**: Ensure that only legitimate services can communicate with each other, leveraging technologies like Spring Security.

**What You Will Learn in This Course:** 📚
– **Securing Communication**: We’ll explore how to secure the communication within the cluster and why it’s essential for your services.
– **Circuit Breaker Pattern**: Discover how to prevent sending requests to a failed service by opening or closing the circuit breaker.
– **Monitoring External Calls**: Learn to monitor external calls and understand the importance of doing so in a distributed system.
– **Observability with Load Balancing**: See load balancing in action and how it contributes to the resilience of your application.
– **Fault Injection**: Understand the power of fault injection for robustness testing.
– **Traffic Management**: Manage traffic to a different version of the app to ensure a seamless rollout of updates.
– **Security**: Secure access to services using JWT tokens and learn how to customize logging for better visibility into your application’s behavior.
– **Monitoring and Observability**: Utilize tools like Kibana, Kiali, and Jagger to monitor your application, gaining a comprehensive view of its performance and health.
