Managing Kubernetes Cost and Performance with Kubecost and NGINX Balancing cost and risk is top of mind for enterprises today. But without sufficient visibility, it is impossible to know if resources are being used effectively or consistently. Kubernetes enables complex deployments of containerized workloads, which are often transient and consume variable amounts of cluster resources. That makes cloud environments a great fit for Kubernetes, because they offer pricing models where you only pay for what you use, instead of having to overprovision in anticipation of peak loads. Of course, cloud vendors charge a premium for that convenience. What if you could unlock the dynamic load balancing of public cloud, without the cost? And what if you could use the same solution for your on‑premises and public cloud deployments? Now you can. Kubecost and NGINX are helping Kubernetes users reduce complexity [ more… ]

Accelerating DDoS Mitigation with eBPF in F5 NGINX App Protect DoS The battle against DDoS attacks continues to transform. In the 2023 DDoS Attack Trends report, F5 Labs analyzed three years of recent data about distributed denial-of-service (DDoS) attacks and found that while attackers still use complex multi‑vector DDoS attacks, they have also shifted to launching more purely application‑layer (Layer 7) attacks. In 2022 alone, the prevalence of Layer 7 attacks grew by 165%. Counts of DDoS attack types, 2020–2022, showing a large increase in the number of application attacks and corresponding reduction in volumetric and multi‑vector attacks. Typically, attackers pursue the easiest path to achieve their goal, whether that means preventing operations of a website or extortion of a target. This rise in Layer 7 attacks may be an indication that it is becoming harder to launch a DDoS attack solely by using a volumetric or [ more… ]
