All three functionalities listed below are available upon enabling Argo. You’ll need to start by enabling Smart Routing above to gain access to Tiered Caching and Tunnel.
Argo’s smart routing algorithm uses real-time network intelligence to route traffic through the fastest Cloudflare network paths, while maintaining open, secure connections to eliminate latency imposed by connection setup.
To enable Argo Smart Routing and gain access to the Argo functionalities listed below, select the enable slider above. Please refer to the Argo Smart Routing knowledge base article for more information.
Argo’s tiered caching technology uses regional tier 1 Cloudflare data centers to propagate content to Cloudflare’s global network, minimizing static content requests to your server, while reducing bandwidth and total costs.
Using a lightweight daemon installed on the origin infrastructure, including containers or virtual machines, Argo Tunnel creates an encrypted tunnel between the nearest Cloudflare data center and an application’s origin server, without opening a public inbound port.
To get started with Argo Tunnel, please refer to the Argo Tunnel quickstart documentation.
This feature is a usage-based product and costs USD $5.00 per month. After exceeding the first gigabyte of traffic between Cloudflare and your visitors, you are charged USD $0.10 per additional gigabyte.
