Fundamentals of Colocation
Server colocation is generally for people who have their own server hardware and need complete control over the host configuration. Colocation experts will home and join a host you have, to a speedy internet link, usually at a secure datacentre, with 24/7 support.
It’s crucial to settle on a colocation provider that has their own data centre or has a presence in one of those top “data hotels.” World Class data centers are located in major industrial cities (New York, London, Frankfurt for example). They can benefit from this convergence of high capacity network connectivity that happens in a significant business center. For example fiber, also metrolinks and ease of connection to significant Points of Presence (POPS) into the significant telcos. For this reason only a very few of those top ISP’s or colocation specialist operate their very own dedicated center ‘s because of the expenses of providing remote connectivity, redundant power sources, air conditioning and filtered fresh air.
Not all of internet connections are equivalent. You truly need to ask if a colocation expert is “multihomed” with the BGP protocol with at least 2 links to Tier One suppliers. Tier One suppliers are extremely big ISP’s or Telco’s who operate their own fiber connections and networks without needing to run traffic (or transit) over the other ISP’s network. A good example of a Tier One supplier would be Level3 communications.
Besides Tier One relations, the colocation expert should have peering arrangements at major exchange stages for example LINX. A peering stage is where numerous ISP’s organize to “fulfill” to exchange traffic between each other instead of pay for transit someone else’s network. In a way they’re “cutting out the middleman!” This not only enhances redundancy but reduces latency; folks are going to have the ability to access the websites and material hosted on your colocated server much quicker if you colo host is nicely peered.
