Overview of Azure Cobalt 100 and NGINX

Azure Cobalt 100 Arm-based processor

Azure’s Cobalt 100 is Microsoft’s first-generation, in-house Arm-based processor. Built on Arm Neoverse N2, Cobalt 100 is a 64-bit CPU that delivers strong performance and energy efficiency for cloud-native, scale-out Linux workloads such as web and application servers, data analytics, open-source databases, and caching systems. Running at 3.4 GHz, Cobalt 100 allocates a dedicated physical core for each vCPU, which helps ensure consistent and predictable performance.

NGINX

NGINX is a high-performance open-source web server, reverse proxy, load balancer, and HTTP cache. Known for its event-driven, asynchronous architecture, NGINX handles high concurrency with low resource usage.

There are three main variants of NGINX:

• Open source NGINX: a free and open-source version available at nginx.org
• NGINX Plus: a Commercial edition of NGINX with features like dynamic reconfig, active health checks, and monitoring
• NGINX Unit: a lightweight, dynamic application server that complements NGINX - find out more at the NGINX website
