All these tools/apps are nicely "packaged" (for ease of installation) and tested for compatibility. This makes Debian distro look monumental, safe, conservative, and always slightly outdated.
Debian is much more stable that any other Linux distribution so it is highly recommended on server environments.
Support Services: Guru-host support almost anything based on Debian. From simple installations up to load balanced fail over cluster using the High Availability project (http://linux-ha.org/). We are also able to offer onsite consultancy.
Due to the nature of complexity we will be able to assist you and offer you our services after a review of your requirements. Please contact us describing what plan you want to achieve. As soon as we receive your email one of our colleagues will contact you the soonest possible.
