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

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

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

  * **[[https://vshosting.cz/|vshosting]]** (Primary location, Czech Republic) – ISO 27001
  * **[[https://www.faster.cz/|Faster]]** (Secondary location, Czech Republic) – ISO 9001 and ISO 27001
  * **[[https://www.vodafone.cz/|Vodafone]]** – ISO 27001
  * **[[https://www.ovhcloud.com/|OVH]]** (Backup location, France)

We prioritize efficiency and low operational overhead, allowing us to maintain competitive hosting prices for [[en:mervis-scada:00-start|Mervis SCADA]] and [[en:mervis-db:10-api|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.
  * **Disaster Recovery:** We regularly test data recovery procedures and system restoration capabilities to ensure business continuity and infrastructure resilience.

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

We maintain a strict security posture across our IT infrastructure to protect customer data. 

//For comprehensive details regarding our regulatory compliance, multi-factor authentication, and NIS2 Directive readiness, please visit our dedicated **[[en:mervis-scada:42-security|Security & NIS2 Compliance]]** page.//

  * **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 validate our security architecture against modern threats.
