HashiCorp Consul is a service mesh solution. A service mesh is a dedicated infrastructure layer that controls service-to-service communication in a microservices architecture. It manages the routing of service requests to other services, performs load balancing, encrypts data, and discovers other services.

▬▬▬▬▬▬ What you’ll learn in 2 Hours ✅ ▬▬▬▬▬▬
► What service mesh is, what problems it solves in microservices architecture
► How service mesh and Consul specifically works
► How Consul works in Kubernetes multi-cluster, hybrid environments with VMs
► Consul Architecture (Control Plane and Data Plane)
► Learn about
Proxy containers
Dynamic Service Discovery
Health Checks and Fault Tolerance
► Learn about secure networking - creating a zero-trust network:
Mutual TLS - mTLS
Authenticated Communication
Control Traffic with Service Intentions
► Hands-on demo 🧑🏽‍💻
create 2 K8s clusters on 2 different cloud platforms
deploy microservices application and Consul on it
configure failover, so in case one service is unhealthy or unreachable it routes the traffic to the healthy service instance on the other cloud platform
