After a lot of digging into, this is how the system is going to be.

System will interact with multiple services to access values and validate inputs based on that. There are over 50 fields in object which need to be validated.
Services will be mostly REST APIs/Database calls and total number of services are around 10. Even if each call takes about a second, it is 10 seconds.

With this in mind, i have come up with Go as viable solution after reading through various forums, blog posts. Next step will be do a small POC, where each request will sleep for 10 seconds and return a response. Hit the API with 1000 requests with 100 concurrent users and see how it fares against Spring REST API!
