Transitioning from Monolith to Microservices: Service Mesh, Kubernetes, and Architecture Evolution

The speaker, Marco Palladino, CTO of Kong, explains why organizations move from monolithic systems to microservices, emphasizing the need for increased team productivity and business scalability.

Key migration patterns are described, including the "ice‑cream" approach (gradual extraction of services), the "Lego" method (partial refactoring), and the "nuclear" strategy (building from scratch), each with its own trade‑offs.

Service mesh is introduced as a design pattern that uses sidecar data‑plane proxies to handle networking, security, and observability without modifying application code, enabling reliable inter‑service communication.

Kubernetes is discussed as the platform that orchestrates pods and sidecar containers, providing a unified control plane for configuring data‑plane proxies and managing resources efficiently.

The importance of handling latency, network reliability, and fault tolerance is highlighted, with recommendations such as intelligent API gateways, health checks, circuit breakers, and progressive rollout techniques.

Event‑driven architectures are presented as an alternative to direct service calls, using systems like Kafka to decouple state propagation and improve resilience.

Kong’s open‑source control plane and data‑plane solutions are showcased as tools that help teams adopt service mesh, Kubernetes, and microservices at scale.
