- Bounded Context , Context Map ,Ubiquitous languages
- Strategic and Tactical design
- Upstream and Downstream
- Context Map strategic design thinking Partnership,Shared kernel,Customer supplier,Conformist,Anticorruption Layer,Open Host Service and Published Language.

|
|
- Database pattern discussion Shared database, Database per service, Saga, API
|
|
- Sync and Asynch communication between Microservices
- Synch and Async: - API Calls using Async Await
- Communication through RabbitMQ, Async, Long wait calls
|
|
- CQRS and event sourcing with Rabbit MQ.
|
|
- Security using JWT token and Single Sign on discussion. Oauth2 and OpenId connect importance and flow.
|
|
- Resiliency, partial failure, http resiliency, circuit pattern using Polly, exponential backoff and health monitoring, Service discovery.
