F5 BIG-IP DNS (formerly Global Traffic Manager - GTM)

Speed, meet security. BIG-IP DNS hyperscales up to 100 million responses per second (RPS) to manage rapid increases in DNS queries.  With a set of features that includes multicore scalability, DNS Express, and IP Anycast integration, BIG-IP DNS handles millions of DNS queries, protects your business from DDoS attacks, and ensures top application performance for users. BIG-IP DNS delivers a real-time, signed DNSSEC query response and DNS firewall services for attack protection and mitigates complex threats by blocking access to malicious domains. Works with what you already have in place. BIG-IP DNS services integrate with DNS zone management solutions, increase DNS performance at the network edge, and mask the DNS back-end infrastructure. That translates into higher productivity, server consolidation, faster responses, and protected DNS management. All-over availability. BIG-IP DNS routes distributed app traffic to keep pace with changing network and user volumes that can overwhelm data centers during peak traffic times. BIG-IP DNS can also be configured as a full proxy for global load balancing applications and DNS across architectures, as well as across the globe. Plus, you can use it in virtual and hybrid cloud environments to extend DNS services and global app availability while keeping centralized control within the data center.
