Our current co-location facility provides a managed network environment (e.g. firewall, etc.) for our servers. We are considering a new co-location facility that offers us more rack space and higher bandwidth, but it doesn't come with all the managed services.
It seems like they will be letting us drink straight from the firehose, so-to-speak.
We have quite a bit of experience configuring network resources for our end-user facilities, but not much experience on the data center side of things since it has been managed in the past.
I guess I'm looking for a good list of things I should be concerned about with this change in configuration.
If we put a basic firewall product (say a SonicWall, for example) in place, what else are we missing? Are we making ourself more susceptible to DoS attacks? Is that something a managed facility would be able to thwart for us?
