Problems<\/strong><\/p>\n

    \n
  1. Clients know too much: Auth, Encryption, etc.<\/li>\n
  2. Hard to change a microservice -> Don’t know who’s using it. Hard to add a new microservice -> No one may use it. Being political.<\/li>\n
  3. Responsibility for the failure in a microservice. What happened when a microservice fails.<\/li>\n
  4. REST is slow<\/li>\n<\/ol>\n

    Solutions – Useful Architectures<\/strong><\/p>\n

      \n
    1. API Gateway\n
        \n
      1. Provides: Auth, Routing,\u00a0Rate Limiting, and Logging and analytics.<\/li>\n
      2. It can be a bottleneck if all internal services access the API gateway. => Anti-Pattern<\/li>\n
      3. Service Mesh. Side-car. Shared library.\n
          \n
        1. Work as a proxy(service discovery, routing).<\/li>\n
        2. Control re-try pattern. e.g. circuit-breaker. Too much retry causes a problem.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n<\/li>\n
        3. Event-Driven\n
            \n
          1. Broadcast -> Subscribe. Being independent of the other services.<\/li>\n<\/ol>\n<\/li>\n
          2. DB for each microservice\n
              \n
            1. local DB can provide local state for each Microservice, which allows independence.<\/li>\n
            2. DB can be a small, cloud-based key-value DB.<\/li>\n<\/ol>\n<\/li>\n
            3. Schema\n
                \n
              1. Very important to keep the consistent schema (contracts) among services.<\/li>\n
              2. Can register all schema in the schema registry, which all microservices will share.<\/li>\n<\/ol>\n<\/li>\n
              3. Serverless\n
                  \n
                1. Can have state by storing in cloud DB or storage.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n

                  Still missing<\/strong><\/p>\n

                    \n
                  1. Durable functions -> Azure functions?<\/li>\n
                  2. Triggers and data from stores to functions -> Maybe Azure event grid is the answer for this.<\/li>\n
                  3. Unified view of the current state -> Hard to check what’s happening long the workflow of the entire system.<\/li>\n<\/ol>\n
