TCS has developed the Indian Railway Ticket booking website , which is being accessed by millions of Indians every hour for transactions.Being such a populous country , you can expect how high the load and scalability of the application should be .My opinion is that , services companies like TCS do what the client asks them to do.There are many research projects done by TCS , including 'Eka' the world's most powerful supercomputer at its time when it was developed. So how come one say TCS is nothing ?
