That's not really 100% true or thumb rule, microservice adaption also depends on increasing user scale. Increasing load on specific service gives invention to move to microservice and design system around adding dedicated DB and other components to that service and horizontally autoscale service.

This is not complete truth at all.. Team scales when there is a heavy load on the service. Team scaling happens when service become too complex to handle and that is why micro services concept came. Gaurav has given indirect statement.

Even if neither of client or team scales, we may need to break the monolith into micro services because of poorly designed/developed application with too many simultaneous feature changes/bug fixes. Greatly appreciate any design/engineering examples of similar use case.

What are your thoughts on a micro services architecture that is organised in a way where you can run in a “local” mode, effectively running the system as a monolith without all of the glue. This would allow a developer to be able to switch of the glue if they are working purely on a functional problem.

@aternous Жыл бұрын

In theory I can see the value of this. I can even think up a way to do it using K8s with docker containers. That said I feel like an analogy might help me describe another perspective. It's like having a car that can turn into a plane and vice versa. Sure, there is value in that but usually to achieve that you need to make sacrifices that would probably leave you with a shittier car and plane. Unless there is some good innovation that can make it seamless and without major downsides to either modes.

The service databases being independent is a good idea (could be served on the same node, but are independent databases).

Some of the benefits you're talking about microservices make it sound like monoliths have code in file (per se) and every service in a micros service interwoven like a saghetti. The reality is that the code changes in monoliths are just as easy. Imho the primary reason of microservices is scale -( I E you scale the service individually based on demand).

@mohinicoder 3 жыл бұрын

Nice explanation. Can we say that monolithic may give faster response than Microservice? In case of Microservices we might need to get data from different services through network but in case of monolithic everything is present in the same project. Though we are started using Microservice architecture in our project I was unable to explain that in an interview because of lack of clarity. Thanks for this Video.

In some cases yes. But a monolith may be sharded by user ranges also. You can now have a look at the "Sharding" video 👍
