Plesk

What do you like best?

Plesk does an excellent job of abstracting complex configuration options in to a consistent user interface. Some similar software only gives you effectively a web interface to the raw config so there is little advantage over manually managing the server.

What do you dislike?

Some of the power of Plesk is not obvious on first use, with some of the best features are split into (free) modules which are not installed by default. Others are only available in the power user mode.

Recommendations to others considering the product:

Older versions of Plesk had some serious issues and lots of online commentary is based from them. Plesk took a bold decision to totally change the design and leave behind some old fashioned practices. It is now the most advanced control panel in my option and you would be remiss in not at least trying it out.

What problems are you solving with the product? What benefits have you realized?

It allows day to day server management to be delegated to end users or less skilled staff.
