A lot of good tips in there. Thank you for sharing. One thing grabbed my attention...

> Hybrid infra. Physical racks where numerous exchange leased lines terminate + AWS. Sometimes, these leased lines go down when the civic body in Mumbai digs up roads.

Isn't it better to fully rely on Cloud and Infra providers in order to completely avoid such instances?

My guess is that the leased lines are a requirement to connect to their partners.

That is correct. Have to have physical racks at approved data centres to terminate exchange leased lines. System audit regulations means that exchange approved auditors walk into the data centres and look at the racks and verify compliance :)

Cloud costs sky rocket when you have applications that use a lot of data. This setup looks like its a very good cost competitive decision
