Today, when there is so much focus on managing complex distributed applications, the question that arises is what to control? Say, you have oracle database instance running on say 100 machines. And some mirror website went down because of oracle instance going down? So, this demands management of oracle database on all the machines. But, then if you manage oracle database instance, what about managing apache server instances. What if it was discovered that website went down because the server configuration setting was changed? So, we come down to managing/controlling apache server and oracle database instances on all the 100 machines. But how do we do? That is the biggest question mark in current computer world? Is there some solution to it? I would say NO! But are people working to find out the solution? I would say YES. Soon, there would be a market leader in this area.
