The reason NEST seemed stable is because there are very clients who use it. Like Siva said, we had almost 1million people logging into Kite every day and only couple of hundred to NEST. Since there are so few users, of course it would have less issues and you’d hardly see anyone reporting issues. This is similar with most other brokers who offer their own platform and NEST.
NEST as a platform can’t handle more customers. That is the reason in the first place all brokers built their own platforms. It works okay until around 4000 to 5000 concurrent customers.
As a business, it is extremely tough to support multiple products, especially when you scale. Every new change needs to be built across all the platforms. The more the platforms, higher the risk on every new update. This slows the business down. So we had to take the decision of shutting it down. This has nothing to do with costs, there were just around 100 to 200 users when we pulled the plug two weeks back, and there was no additional cost running it.
