Monolithic vs Microservices ?

One of the biggest decisions in software architecture today is:
Do we build a Monolith or embrace Microservices?

💻 Monolithic Approach

1-Everything bundled into one codebase.
2-Simple to start but becomes hard to scale.
3-One bug can impact the entire system.

💻 Microservices Approach

1-Services are independent (Catalog, Basket, Discount, Ordering, etc.).
2-Each can use the best-fit database (MongoDB, Redis, PostgreSQL, MySQL).
3-Easier to scale, deploy, and maintain.
4-Uses tools like RabbitMQ for async communication and API Gateway for request handling.
5-As a Java developer, I’ve seen how shifting from Monolith to Microservices transforms businesses:
✅ Faster feature delivery
✅ Improved scalability
✅ Greater resilience
But here’s the real challenge: migrating isn’t just technical it’s cultural and strategic.

I’d love to hear from you:
Are you still working with a Monolithic system?
Or have you transitioned to Microservices already?
