SYSTEMS:
The Océano infrastructure consists of 3 tiers: front-end IP sprayers
and
load balancers (e.g. Network Dispatchers), a pool of commodity Dolphin
servers, and backend Whale servers, all interconnected by switches.
An
Océano farm will provide a "freepool" of Dolphins,
which are available to
be leased to customers. For example, when the load on one customer
drops
below some level, one of its Dolphins is quiesced. This Dolphin is then
"scrubbed" of any residual customer data, and assigned to
the freepool.
Later, when the load on another customer exceeds some trigger level,
a
freepool Dolphin is primed with the necessary software and data
to
acquire the personality of that customer. When this priming completes,
the network infrastructure (e.g. VLANs, Network Dispatcher) is reconfigured
to incorporate the new Dolphin into its new domain.
