IBM Sponsor Talk:

A groundbreaking addition to the DNS-OARC workshop, Day 1 featured a pioneering sponsor talk by Ekim Maurer of IBM. Addressing a pressing challenge faced by enterprises when deploying Internet based services — latency — Maurer’s session advocated for an expanded role of DNS in traffic steering and Global Server Load Balancing. Utilizing data-driven insights, the talk outlined a reference architecture, delving into various options for optimizing DNS pathways and enhancing connection performance. IBM ended the talk by soliciting input from the audience for feedback on their approach and methodology.
