Is NIS okay for a centralized working environment?

I am working for a web hosting company. We work in red hat linux environment and the employees at present are having their data stored in individual systems. We wish to have a centralized environment, so that users can log in to a server with their user names irrespective of the systems they will set. Also, this could facilitate
easy backup. we have about 70 systems, 90% linux machines. The number will grow in future.
I am good in NIS, but not at all with LDAP. Is it okay if I suggest NIS?

I have close to none experience with NIS, but from what I've read NIS is a very old technology with have been replaced by LDAP. I guess NIS still works, but I would (strongly) suggest that you get to know LDAP before making any decision about running NIS.

See here for really good NIS & LDAP HOWTOs(, but the fundamental issue is security. NIS security is minimal, including all transmissions in plaintext. If you want secure, use LDAP with TLS.
Interestingly, the RHEL Deployment guide has a whole chapter on LDAP HOWTO, but very little on NIS ...
