DNS over TLS (DoT) and DNS over HTTPS (DoH) are two emerging technologies for securing Domain Name System (DNS) traffic. In this post we take a look at the history of DNS and show how to implement DoT, DoH, and a DNS filter using NGINX Open Source and NGINX Plus.

We help you avoid the 10 most common NGINX configuration errors, explaining the problems caused by each and how to fix them. Errors include insufficient file descriptors per worker, disabling proxy buffering, and not using upstream groups and keepalive connections.

NGINX Plus R26 introduces faster JWT validation with JSON Web Key Set caching and hardened TLS handshakes for improved security. New NGINX JavaScript features include enhanced support for asynchronous functions and an implementation of the WebCrypto API.

gRPC provides the speed and flexibility developers need to design and deploy modern applications, but its open nature makes it highly vulnerable to Layer 7 DoS attacks. NGINX App Protect DoS protects your gRPC apps from these crippling attacks.

Great ready for Microservices March 2022! This year we focus on Kubernetes networking, a key component of production-grade Kubernetes that is often not well understood. Preview what you'll learn during the four-week series and register for access to the labs.

Releases 3.20 through 3.22 of the NGINX Controller Application Delivery Module combine to improve our powerful governance, observability, and operations platform for NGINX Plus deployments and the applications they support. Get all the details about the new features.

We performance test NGINX Ingress Controller and the default Red Hat OpenShift Router in an OpenShift Cloud Platform cluster while scaling the number of backends up and down. The Router experiences significant latency and errors, but NGINX Ingress Controller almost none.

Do you need an Ingress controller to accept traffic into your Kubernetes environment? To help you decide, we offer a primer on the other services for getting external traffic into a cluster: kube-proxy, Cluster IP, NodePort, and LoadBalancer.

We recently jumped the NGINX Ingress Controller version number from 1.x to 2.x, to signal compatibility with version 1 of the Kubernetes API (released in Kubernetes 1.22). Find out why this matters and how to keep your Kubernetes apps running smoothly as versions change.

During 2021 we published more than 50 posts on the NGINX blog, covering a wide range of topics. Here we review the eight that were most popular among our readers, giving you a chance to catch up on big news and important insights you might have missed.
