Clarity CA is a very stable tool. It has been around for a long time.

The scalability is good because CA's IT Client Manager has Enterprise Manager, which is like a big server. Below that there is a domain manager and below the domain manager there are scalability servers. If we want to add something, we can easily do so just by adding another scalability server, because we already have the structure. If the company is growing, we just add another scalability server on the other site, connect it to the Enterprise Manager, and we are done.
