The question asked by many clients is “What is so special about DNS?” Most are familiar with the early days of the commercialized internet when they began delegating their DNS to their preferred ISP. For many, that approach has literally remained unchanged 15-20 years later with the mindset of set it and forget it. Delegation consists of a couple of authoritative nameserves responding via the ISP and the customer is on their way. This approach is very critical to rethink in terms of DNS and how it represents a single point of failure. Second, most ISPs do not offer any sort of intelligent response options, thus this very vanilla DNS approach with a single point of failure can throw out a Business Continuity Plan (BCP) immediately. Various BCPs have existed for years and have always represented the traditional N+1 model, however, the aforementioned deployment delegating DNS to a single provider, predominantly in an authoritative fashion can really leave an organization exposed.
Imagine if you line up for the 100 Meter race, lock into the starting block and set yourself to run hard as you possibly can, who is thinking about the starting gun? Yet the race will not start until the gun is fired. Without it there is literally no medals for the winners, no spent energy and certainly no race. All of the prep work and training performed over months and years for that moment can’t commence until the gun is fired signaling the start of the race. DNS is that firing gun and must work properly at all times, otherwise nothing resolves and all of the capital and hard work put into a wide area network design and local LAN infrastructure in a datacenter was built for nothing.
However, there is no need to be a magician and pull DNS out of a hat. Instead, DNS tricks can be implemented to increase the availability of services to your users querying your environment and add a level of continuity to your BCP.
DNS Tricks in a Hybrid Design:
Oracle Dyn’s leading Active Failover allows users granular active/passive responses between two endpoints such as a datacenter and cloud environment’s locations. In the event of a disaster, an organization can failover from their cloud instance back to the closest datacenter they have collocation residing in. The beauty of the Oracle Dyn solution is that it is agnostic to the environment and presently we serve locations both public and private around the world.
This failover, which happens at the apex of the domain, is important in the world of resolving information in a decentralized topology where users require immediate resolution to their request.
Managing mult-environments already poses tremendous burden internally to IT staff, why not reduce this by adding an easy to deploy layer of technology with Advanced Managed DNS features? When we say “Managed” the user is equally in control via an API or a UI that provides an added level of ease.
Other Important Use Cases of DNS Power Tricks:
- Geographical Load Balancing
- Security with DDOS Mitigation & DNSSEC options
- Monitors which can identify possible failures
- Secondary DNS, not to be misunderstood as idle nameservers.
