3. monolithic vs microservices Monolithic Microservices One large service is aggregation of many business logics. One business logic is independent. One large service is aggregation of many services.
4. The challenges of microservices • Hard to define service boundaries. • Hard to ensure data consistency. • Service Discovery • Observability • Zero-Trust networking workload (AuthN/AuthZ) etc...
5. The challenges of microservices • Hard to define service boundaries. • Hard to ensure data consistency. • Service Discovery • Observability • Zero-Trust networking workload (AuthN/AuthZ) etc... Service Mesh Can Service Mesh be the Silver Bullet to overcome these challenges of microservices..…?
6. What is Service Mesh? • Provide service management layer on your infrastructure. • The main components of Service Mesh are ◦ Data Plane ▪ Provide L4/L7 related networking ability as reverse proxy. ▪ Split out only business logic from services. ◦ Control Plane ▪ Manage Data Planes Disentangle common networking related workloads from services.

9. Envoy • Envoy is a de-facto standard data plane implementation for Service Mesh. • L4/L7 reverse proxy optimized for cloud native workload. ◦ Dynamic configurable ◦ Custom L4/L7 filter ◦ Advanced logging/stats observability ◦ High performance • Not only for data plane on Service Mesh! ◦ We can use envoy as edge proxy.
10. Challenges of Service Mesh • Hard to introduce existing large-scaled microservices • Complexity explosion • Latency • Hard to manage large-scaled Service Mesh ◦ e.g. Istio config is very very very complex....
11. Service Mesh is not so cute….
