Options for DNS in networking address growing challenges

A need for modern DNS in networking has grown out of increased cloud use and distributed applications. Now, vendors are offering these services for internal enterprise use. For the first 25 years or so of the internet's existence, the original domain name system, or DNS, could locate internet domain names and translate them into IP addresses to quickly connect users to remote hosts, eliminating the need to keep the equivalent of IP phone books on hand. Many free, open source DNS tools worked well when webpages were largely static, and the protocol created in 1983 by Internet Hall of Famer Paul Mockapetris could handle the load. But the growth of cloud-based services, microservices and distributed applications has led to the need for modern approaches to DNS in networking. Organizations face new DNS challenges in managing applications built in components and hosted in different locations that all need to be linked together, according to IDC senior analyst Brandon Butler. The global DDI market, which is made up of three core network services that enable communications over IP networks -- DNS, Dynamic Host Configuration Protocol and IP Address Management Protocol -- is expected to grow from $690 million in 2016 to $3.08 billion by 2023, according to market research consultancy Stratistics MRC. Cloud computing, the use of dynamic applications and mobility are expected to play a large role in DDI market growth -- particularly in North America.
