- 5. The Monolithic Architecture ● It is a GOOD architecture when commencing project ● Most of technologies in stack is EASY to implement and SYNCHRONIZE throughout a project ● Only one package which leads to DEPLOY application more EASIER ● SMALL TEAM maintains a project
- 6. MonolithicArchitecture Component dependencies Components stick hardly which leads to side effect on application Lack of product innovations Significantly change when apply a new technology Non-optimization resources Huge a large of server resource to start an application Long time to add new features Waste a lot of time to add a new feature and restructure a project hardly Obstacle when deployment mandatory deployment an application even slight change Difficult to scale application Cann’t split service to scale particular services

- 14. Microservices only rely on each other’s public API Principle1 “ Micro-service A Micro-service B Public API Never
- 15. Secure your services Principle2 “API Gateway API Gateway (“Front door”) API Throttling Authentication & Authorization • Client–to–server, as well as service– to–service • Token-based auth (JWT token) • IAM-based Authentication
- 16. Be a good citizen within ecosystem Principle3 “ Micro-service A Distributed tracking and monitoring • Which services were involved in a request? • How did downstream dependencies platform Micro-service B Shared metrics • E.g. request time, time to first byte Distributed tracking • E.g. Zipkin, Spring Cloud Sleuth
- 20. ● This application is cross-platform for both the server and client side which is based on .NET Cor, it's capable of running on Linux or Windows containers depending on your Docker host. It also has a Flutter mobile app that supports Android and iOS ● The architecture proposes a microservice oriented architecture implementation with multiple autonomous microservices ● The microservices also showcase different approaches from simple CRUD to more elaborate DDD/CQRS patterns Overview
- 21. ● The architecture also includes an implementation of the API Gateway pattern, to publish simplified APIs and include additional security measures for hiding/securing the internal microservices from the client apps or outside consumers. ● Currently these API Gateways only perform request forwarding to internal microservices and custom aggregators, giving the clients then experience of a single base URL APIGateway
- 22. ● There are different types of microservices according to their internal architectural pattern and approaches depending on their purposes. For example ○ Identity micro-service is using ASP.NET Core Identity & Identity security token service ○ Core micro-service is an CRUD micro- service using Redis cache ○ Daynghe micro-service is applying domain-driven design using DDD pattern InternalArchitecturePatterns
- 23. ● There are eight SQL Server databases, but they are all deployed to a single container, to keep memory requirements as low as possible. This is not a recommended approach for production deployment, where you should use high availability solutions. ● There are also one Redis, in separate containers, as a sample of two widely used NO- SQL databases.
