Fork-lifting legacy monitoring systems and migrating to the cloud
Within data centres and telecommunications points of presence, many
legacy monitoring solutions exist. The architecture is typically rack
mounted hardware that has wired sensors or probes. The hardware has a
built-in web server and in most cases also a text based cli. The
connectivity is typically via an internal Ethernet network and
optionally out of band connectivity via a GSM modem. The user is
required to connect out of band to the web server or cli on the
hardware. This connection entails an incoming session over the modem
that requires approval from the service provider. The service provider
usually discourages these type of connections due to hacking.
Additionally, the network address of the hardware needs to be associated
with a name resolution system and often this is a dynamic DNS type
service. This architecture is the basis for many types of botnet
