- Workers are small programs that run inside Cloudflare’s global network.
- They run close to each user, in more than 300 cities.
- They support WebSockets, which web trading terminals depend on.
- SSL and DDoS protection are part of the platform.
What are Cloudflare Workers?
Cloudflare Workers are a serverless platform: you deploy code, and Cloudflare runs it in its data centres around the world. There is no server to choose, size or patch. A request from a trader in Dubai is handled in or near Dubai; one from São Paulo is handled nearby.
Why it suits web trading terminals
- Proximity: assets and connections are handled close to each trader.
- WebSockets: live quotes and order updates pass through reliably.
- Security: HTTPS and network-level DDoS protection are built in.
- Elasticity: traffic spikes around news events do not require new servers.
Compared with a VPS
A VPS with a reverse proxy works, but it is a single location that your team must maintain: operating system updates, proxy configuration, certificates, monitoring and scaling. With Workers, those responsibilities largely disappear. See the hosting comparison.
What it costs
Cloudflare offers a free Workers plan with a daily request allowance and low-cost paid plans beyond it. Many brokers’ web terminal traffic fits comfortably within these plans. Check Cloudflare’s current pricing for exact limits.
Frequently asked questions
Do I need a paid Cloudflare plan?
