Ultimately, each organization’s unique requirements, existing infrastructure, traffic
patterns, applications, growth plans, and politics will determine which architecture
offers the best starting point. There are many variations possible based on these
architectures:
• Organizations that are new to GSLB and have a complex Infoblox DNS
architecture with the capacity to handle the DNS request volume should start
with a Delegation architecture. This is a minimally disruptive way to start using
intelligent GSLB services.
• Delegation is often the only option when internal politics or policies preclude
the ability to change any part of the existing Authoritative architecture.
• Larger organizations with higher volumes of DNS requests, concerns about
DNS DoS attacks, a need to deploy DNSSEC, and a desire to avoid using
CNAMEs and subzones will likely find the Authoritative Screening architecture
a better fit for their requirements.
