Quick answer: A 1 Gbps port comfortably serves most websites, apps and game servers. Choose 10 Gbps for streaming, large file distribution, busy CDN origins, backup targets or heavy inter-server replication. 20 Gbps suits sustained very high throughput. Availability and pricing depend on the location and configuration — confirm via ticket.
Overview
Port speed defines the ceiling of your traffic at any moment. To pick correctly, estimate your peak concurrent throughput, not the monthly total: 1 Gbps moves ~125 MB/s — that is roughly 320 TB in a month if fully saturated 24/7, which very few workloads do. Cloud2Y's network is built on Cisco equipment across Ukraine (Kyiv, Lviv), Amsterdam and Singapore.
Before you start
- Your peak traffic estimate: concurrent users × average stream/download rate.
- The traffic pattern: steady (streaming) vs bursty (news site spikes, nightly backups).
- Growth expectations — switching ports later is possible but may need a maintenance window.
Step-by-step guide
- Estimate peak Mbps. Example: 1 000 concurrent viewers of a 4 Mbps stream = 4 Gbps → 10G port.
- Add headroom: run a port at ~50–70% of capacity at peak, not 95%.
- Check the disk side: 10G+ only pays off if storage can feed it (NVMe or many-disk arrays).
- Pick: 1G — sites, shops, APIs, most game servers; 10G — video, file mirrors, backup/replication targets, busy origins; 20G — sustained multi-gigabit delivery.
- Order with the chosen option, or ask for an upgrade on an existing server.
Common issues
- Paying for 10G but pushing 300 Mbps: measure before you buy — upgrading later is easy.
- 10G port, 1G results: single TCP streams rarely fill 10G — test with parallel streams and check NIC offloads and CPU interrupts.
- Confusing port speed with traffic volume: the port is speed; volume is a separate parameter of your plan.
When to contact support
Ask support to confirm 10G/20G availability and pricing for your target location and chassis before ordering, or for help interpreting your traffic graphs when choosing.
Frequently asked questions
Is 1 Gbps enough for a busy website?
Usually yes — 1 Gbps moves roughly 125 MB per second, which covers most websites, shops and APIs with plenty of headroom. Measure your real peaks before paying for more.
When does 10G actually pay off?
10G pays off for streaming, large file distribution, busy CDN origins, backup targets and replication-heavy clusters — workloads that sustain multi-gigabit throughput.
How much does a 10G or 20G port cost?
Pricing depends on the location and your server configuration, so there is no single list price. Request a quote via support ticket for your specific machine and data center.
