## Microsoft Azure NGINXaaS - An Overview

Azure NGINXaaS (NGINX as a Service for Azure) is a managed NGINX deployment on Azure that provides load balancing, reverse proxy, and API gateway capabilities. Applications Manager's [Azure NGINXaaS monitoring](https://www.manageengine.com/products/applications_manager/help/azure-network-management-delivery-monitoring.html#h7) gives you comprehensive insight into NCU provisioning efficiency, system CPU usage, connection health, HTTP request/response status codes, cache hit ratios, per-worker statistics, upstream peer health, and TCP/UDP stream metrics.
