LTM & DNS: Traffic Management for Modern Applications

BIG-IP LTM remains the most capable full proxy in the industry, and most estates use a fraction of it. We design and tune LTM and BIG-IP DNS for the way applications are actually built and consumed now.

Local Traffic Manager

• Protocols – HTTP/2 end to end or offloaded, HTTP/3 and QUIC on the client side, WebSockets and gRPC, with TCP profiles tuned per network path instead of left at defaults.
• TLS – TLS 1.3, ECDSA and RSA certificate pairs, OCSP stapling, client-certificate authentication, and automated certificate renewal through your PKI or ACME.
• Health and persistence – monitors that reflect real application health, persistence that survives failover, and priority groups and slow-ramp for safe deployments.
• Observability – Telemetry Streaming to Splunk, Elastic or Prometheus, request logging and AVR analytics, so performance problems are measured rather than argued about.

BIG-IP DNS

• Global server load balancing across data centers, clouds and Distributed Cloud, with topology, geolocation and health-driven steering.
• DNS Express and DNS caching for millions of queries per second, DNSSEC signing, and protection against DNS floods and amplification.
• Wide IP designs that turn application migrations into a DNS change rather than a network change.

Applications we optimise most

On-premise Microsoft Exchange, SharePoint and Active Directory Federation Services; Citrix and Omnissa Horizon virtual desktops; Java and .NET application tiers; API gateways; and Kubernetes services published through Container Ingress Services.
