Infrastructure
The architecture of conversion.
Technical choices directly impact your bottom line. We handle the complex infrastructure so you can focus on selling.
Flash sale resiliency
In legacy clouds, unpredictable traffic spikes cause 'noisy neighbor' issues where other users consume your server's resources. Nubis provides dedicated bare-metal nodes — 100% physically isolated compute during peak traffic.
Localized edge routing
Every 100ms of latency can drop sales by 1%. Traditional clouds route African traffic through Europe. Nubis operates local PoPs within the continent — customer requests travel shorter physical distances and return checkout data instantly.
PCI DSS hardware ready
Processing payments requires strict PCI compliance. Virtualized environments make securing memory and storage complex. With Nubis, you control the physical layer, making compliance audits simpler and customer card data secure at the hardware level.
High-bandwidth inventory sync
Omnichannel retail requires syncing millions of SKUs between your cloud app and physical warehouses. Our 40 Gbps internal network backbone allows massive database replicas to sync continuously without affecting storefront performance.

High-speed edge caching
Serves product catalogs instantly from memory.
Bare-metal app servers
Unthrottled compute for complex checkout logic.
Synchronous DB cluster
Multi-AZ replicated inventory management.
Example
# Varnish Edge Cache Configuration
# Optimized for high-throughput retail
backend default {
.host = "10.0.0.5";
.port = "8080";
.probe = {
.url = "/health";
.timeout = 1s;
.interval = 5s;
.window = 5;
.threshold = 3;
}
}
sub vcl_recv {
# Bypass cache for checkout & cart
if (req.url ~ "^/(cart|checkout|api)") {
return (pass);
}
# Strip tracking cookies for cache hits
if (req.http.Cookie) {
set req.http.Cookie = regsuball(
req.http.Cookie,
"(^|; ) *__utm.=[^;]+;? *", "\1"
);
}
return (hash);

Why bare-metal matters for retail
The virtualization tax. When you rent a server on major cloud providers, you're renting a virtual machine. A middleman software layer called a hypervisor splits a physical computer into smaller rental units — consuming up to 30% of the server's computing power just to manage this splitting. For an e-commerce store, this means your storefront runs slower, especially during peak traffic.
The Nubis approach. Nubis gives you bare-metal access. No hypervisor, no sharing. You get the entire physical machine. When a user clicks checkout, the server processes that request directly on the hardware.
The business result. Faster page loads correlate directly to lower bounce rates and higher conversion rates. By removing abstraction layers, your retail platform functions predictably — avoiding sudden slowdowns when a cloud neighbor gets a burst of traffic.
