and Fault Tolerant
IDAutomation designed the BCGen on-line barcode generator cloud to be low
latency, high-performance and fault-tolerant, with multiple load balancing servers in different locations, each
with complete redundancy in DNS, power and network connectivity. A DNS failover
system exists on each server so that if one server goes off-line, DNS will
redirect clients to other functioning BCGen servers.
The DNS cache is set to a maximum of 15 seconds
on all BCGen servers, which allows quick failover if one server should go
offline. One or more of the BCGen servers are hosted in a Midwest
datacenter, while at least one other BCGen server is hosted in the east U.S.
