# Performance at Scale

Recombee is built as a real-time, high-performance, distributed system to achieve the following objectives.

![](https://www.recombee.com/img/how-it-works/performance-at-scale-m.png)

**Process** vast volumes of recommendation requests for high-traffic websites (up to 30k recommendations per second).

**Support real-time model updates** and incremental training to quickly adapt to emerging trends and catalog changes.

**Ensure** fault tolerance and maintain **high service availability**.

**Provide** robust **security and data protection** at all levels.

## Architecture

Recombee operates on several hundred high-performance servers, hosting thousands of applications that interact within a micro-service architecture.

This setup includes multiple layers of storage and distributed processing components, all equipped with self-healing and self-recovery capabilities.

These features ensure that Recombee maintains high system availability and reliability.

## Geographical Regions

Users depending on our recommendations or search results are spread across the globe. Recombee operates its clusters in several geographic regions.

This allows you to **choose the region** that is closest to your users or servers in terms of **latency.**

Currently, you can choose from the following regions:

* US West Coast
* Canadian East Coast
* Europe (Germany)
* Australia (Sydney)
