The document discusses microservices architecture, detailing its definition, need, characteristics, limitations, and trade-offs, emphasizing its distinction from monolithic applications. Key points include the importance of modularity, the challenges of distributed systems, and crucial considerations before adopting microservices. The author advises against starting with microservices without clarity on future project evolution and highlights the necessity of independent service deployment and management.
Do you need microservices architecture?

- 3. Agenda What is microservices architecture The need Characteristics Examples Microservices architecture – The not-so-good parts Limitations Trade-Offs Starting with a modular monolith Don’t start with microservices if you are not sure about the future Modularity is the key Transforming a modular monolith to microservices
- 4. Microservices architecture – The Need What we have now – Monolith! A single packaged deployment for all of the application Complexity in Functionality Scaling Fault Tolerance Convoys Law Governance “The growing demand for agility, flexibility, and scalability to meet rapidly evolving business needs creates a strong need for a faster and more efficient delivery of software” - Arun Gupta
- 5. Microservices architecture Approach to developing a single application as a suite of small set of collaborating services.
- 6. Microservices architecture - Example
- 7. Microservices architecture - Characteristics Organized around Business Capabilities Smart endpoints and dumb pipes Independent Governance Independent Technical Stack Independent Deployment Improved fault isolation Eventual Consistency for Data Consumer first interfaces
- 8. Microservices architecture - Limitations Significant Operations Overhead Implicit Interfaces Distributed System Complexity Additional tools for Service Registration and Service Discovery - Zookeeper, Doozer, Etcd, Eureka
- 9. DevOps Tool Set Distributed systems => High level of Automation => Need to depend on more tools => Need to have good DevOps skills in the team

- 13. Do you need microservices architecture The “Hype” Cycle Microservices is not a solution to modularity problems Don’t start with microservices if you are not sure about the future evolutions Use the “Bounded context” concept in the Eric Evan’s Domain Driven Design
- 14. Summary : Answer these before you choose Does your services represents different business cases/domains..? Does the services needs to be deployed and managed independently..? Does different parts of the application has different scaling/Technology needs..?
