DNS is still the Internet’s phone book, but it also has a much bigger role in this era of cloud infrastructure and applications.
Modern DNS services help organizations manage the increasing number of web applications and other cloud-based workloads, whose complexity is at an all-time high. Kyle York, vice president of product strategy for Oracle Cloud Infrastructure, outlined these benefits of DNS during an appearance on This Week in Enterprise Tech.
Many people think of DNS just as the protocol, or as the products that are built around it by DDI vendors and authoritative DNS providers. But at its core, it’s a common architecture for all the things on the Internet that use the IP space and need to be named, York said.
“It’s really the glue and the first interaction that your users have with your enterprise, and we believe it is some of the most important and critical components of the infrastructure landscape,” York said.
With that in mind, some of the modern benefits of DNS include:
Disaster recovery: DNS services can reroute traffic if network infrastructure fails during a disaster.
Load balancing: When traffic spikes on one part of the network, DNS services can move some of the traffic to under-utilized parts of the network, ensuring optimal performance.
Geographic traffic routing: DNS services enable organizations to direct traffic to specific web servers, applications or other endpoints based on where the traffic originated.
Latency-based traffic steering: This technology provides the fastest available connection from user to enterprise endpoint.
Despite the benefits of DNS services, many enterprises are slow to adopt and still rely on BIND servers and other on-premises infrastructure. That approach isn’t sufficient to combat today’s security threats, York said.
A lot of organizations do use multiple DNS providers, however, which Oracle Dyn actually recommends from a security perspective. In those cases, organizations either rely on one primary vendor and use a secondary provider where needed, or they use both as primary vendors for different scenarios.
“We’re not sitting here telling you to throw out that DNS server or DDI provider,” York said.
