Monolythic and Microservices Architecture

Monolithic Architecture means the whole application is built as a single unit using the same tech stack.
For example, if I use MERN stack, then my entire project — authentication, payments, cart, everything — will be built using MongoDB, Express.js, React, and Node.js only.

Microservices Architecture means the application is broken into smaller, independent services, and each service can use its own tech stack.
For example:

• Authentication service uses AWS + Node.js with PostgreSQL to verify users and return JWT tokens.

• Payment service is built with Go.

• Cart service is built with Java.

This way, each part works independently, can be scaled separately, and can use the best technology for its job.

What to use ? Microservices | Monolythic Architecture

let say we have a small team size so going with monolythic will be much helpful small team size everyone know that tech stack but in this one issue is if i need to scale let say AUTH and one more service so i need to scale my whole application thats not the scenario in case of microservices in microservices if i need to scale so easily with the power of manifest files (YAML ) we can scale the deployment that part and also descale on demand this is benifit mostly used in Big Big MNCS

Which Architecture Your company use ? Micro / monolythic or some other pls let us know in comments??
