Deliver app performance, security, and availability
DNS hyperscales and secures your infrastructure during high query volumes and DDoS attacks, making sure apps are highly available—even between multiple instances and across hybrid environments.
BIG-IP DNS
BIG-IP DNS improves the performance and availability of your global applications by sending users to the closest or best-performing physical, virtual, or cloud environment. It also hyperscales and secures your DNS infrastructure from DDoS attacks.
Speed and security
BIG-IP DNS can hyperscale 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.
Always-on 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.
Integrates with your infrastructure
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.
Scaling BIG-IP Services with BIG-IP DNS
With network traffic growing exponentially to support new mobile users and web services, service providers need a scalable, secure DNS solution. BIG-IP responds to DNS queries, enables you to optimize your LDNS infrastructure with lower latency—and delivers a better quality of experience.
Superior DNS Performance
Manages query responses with multicore scalability, handling spikes in DNS query volumes.
DNS Firewall Services
Validates query requests, mitigates malicious communications, absorbs DDoS attacks, and more.
DNSSEC Protection
Protects LDNS servers from cache poisoning and man-in-the-middle attacks with real-time DNSSEC.
Global Server Load Balancing
Supports application requirements across data center and cloud environments while keeping apps available.
Continual Monitoring and Automated Failover
Gives you the flexibility to shift traffic to a backup data center and fail over an entire site, or just control the affected apps.
Location-Based Routing
Routes clients to the nearest data center with geolocation-based load balancing for the best user experience.
Deploy however you want
Cloud
F5 application services work the same way in the public and private cloud as they do in the data center.
Virtual Editions
BIG-IP VEs have the same features as those that run on F5 hardware—and you can deploy them on any hypervisor or select cloud provider.
Hardware
Both the BIG-IP family of devices and the VIPRION chassis are purpose-built, powerful hardware that F5 software runs on.
INTRO TO BIG-IP DNS LOAD BALANCING
Jason Rahm introduces the overall strategy of BIG-IP DNS load balancing, and how it differs from BIG-IP LTM options.
TAKE CONTROL OF GLOBAL APPLICATION SERVICES
Ensure the performance and availability of your apps by seamlessly controlling BIG-IP DNS instances from a dedicated management dashboard.
