In the second post in our API gateway series, Liam shows you how to batten down the hatches on your API services. You can use rate limiting, access restrictions, request size limits, and request body validation to frustrate illegitimate or overly burdensome requests.
NGINX Plus R23 introduces new features including health checks for backend gRPC servers, unprivileged installation, support for the OpenID Connect PKCE extension, finer-grained control over TLS connections, a new method of setting cookie flags, and NGINX JavaScript enhancements.
We show how to use the NGINX JavaScript module to capture data about requests that cause errors, with enough details to be useful for debugging and troubleshooting, while not cluttering the log with this information about requests that didn't experience errors.
NGINX Plus R22 introduces new features including support for OCSP to verify certificate revocation for mutual TLS, use of multiple OIDC IdPs in a configuration, real-time tracking of request and connection limiting on the NGINX Plus dashboard, and NGINX JavaScript enhancements.
NGINX Plus R21 is more reliable and secure than ever, importing numerous bug fixes from NGINX Open Source. New variable support in gRPC proxying extends dynamic, API‑driven routing policies to gRPC workloads, and the NGINX JavaScript module has been enhanced, particularly with respect to subrequests.
In this solution, we use NGINX Plus's active health checks and key-value store to track and store application status across multiple sites, and NGINX JavaScript to update DNS records maintained by BIG-IP DNS and DNS Load Balancer Cloud Service, based on the status information.
One of the biggest challenges in scaling deployments on the Internet of Things is device management, particularly over-the-air updates, commonly called OTA. Guest blogger DeveloperSteve shows how to automate OTA using NGINX as an API gateway, along with the NGINX JavaScript module.
NGINX Plus R18 introduces dynamic loading of SSL/TLS certificates, enhances our OpenID Connect reference implementation, and supports port ranges for virtual servers. It also includes enhancements to the key-value store, health checks, NGINX Plus clustering, and the NGINX JavaScript module.
This blog, based on a real customer use case, explains how to use the NGINX JavaScript module to apply a "virtual patch" for a problem in a backend application that can't be modified. In this case, the app couldn't process HTTP requests with lowercase method names.
The NGINX JavaScript module released with NGINX Plus R15 supports subrequests, adding a whole new class of use cases for NGINX Plus. This complete example also uses the NGINX Plus API and Key-Value modules to convert client API requests to separate requests to the microservices APIs that make up an app.
