====== Cloud Infrastructure ======

===== Data Centers =====

All Mervis cloud services are hosted in top-tier, certified data centers to ensure reliability and security:

  * **Faster** (Primary location, Czech Republic) – ISO 9001 and ISO 27001
  * **vshosting** – ISO 27001
  * **Vodafone** – ISO 27001
  * **OVH** (Backup location, France)

We prioritize efficiency and low operational overhead, allowing us to maintain competitive hosting prices for Mervis SCADA and Mervis DB.

===== Technology =====

Our infrastructure utilizes a hybrid of Windows and Linux operating systems. The core software applications are developed **in-house**, which eliminates third-party licensing fees and allows us to fine-tune performance specifically for SCADA and IoT workloads. 

===== Availability =====

While we do not offer a formal SLA, our historical availability has consistently ranged between **99.5% and 99.95%** annually over the last five years.

===== Backup & Recovery =====

  * **Backup Cycle:** Data is backed up every **24 hours**.
  * **Redundancy:** Backups are stored in **two independent locations** outside the primary data center.
  * **Critical Infrastructure:** As a provider for state critical infrastructure projects, we regularly test data recovery procedures and system restoration capabilities.

===== Security & Maintenance =====

We maintain a strict security posture to protect customer data:

  * **Encryption:** Mervis SCADA and Mervis DB utilize **HTTPS** (Let’s Encrypt) for secure communication. 
  * **Legacy Support:** Unencrypted channels remain available for legacy BMS and control systems that lack encryption support, though secure connections are strongly recommended.
  * **Audits & Updates:** We perform regular server updates and undergo **penetration testing** to ensure compliance with security standards required by critical infrastructure clients.

==== Connectivity ====

Devices connect to the cloud platform via our proprietary communication infrastructure:
  * **[[en:mervis-proxy:00-start|Mervis Proxy]]** (Standard connection)
  * **[[en:mervis-proxy:00-start|Mervis CloudAccess]]** (High-speed, low-latency solution)
