Zataca is a technology consultancy specialized in custom software development, telecommunications, digitalization solutions, Big Data, Machine Learning, and artificial intelligence, among other services. Founded in 2015, it has carried out more than a hundred projects in Spain and Latin America for clients from a wide variety of sectors, establishing itself as a trusted partner for companies seeking to drive their digital transformation.
For this project, we have designed and implemented a high-performance virtualization infrastructure based on a Proxmox VE cluster with Ceph distributed storage, which provides the necessary resilience against failures and allows the platform to scale easily. In addition, the infrastructure has been deployed in a region with 3 availability zones (3AZ), which means that the cluster nodes are physically distributed across three independent locations within the same region, ensuring greater fault tolerance, as the failure of an entire zone does not compromise service continuity. This environment serves as the core for running the company’s main services, offering a stable, centralized, and highly available foundation.
The solution is reinforced with a backup system using Proxmox Backup Server (PBS), employing multiple PBS servers distributed across different locations and even in different countries. Thanks to this strategy, data is protected both locally and geographically, ensuring availability even in the event of major disasters, and allowing the establishment of a solid disaster recovery plan (DRP) that guarantees business continuity even in critical scenarios. This enables efficient backups and ensures data protection against any incident. Likewise, system restoration can be carried out quickly and securely, significantly increasing the reliability of the production environment.
In the area of networking and security, we have carried out complete segmentation through VLANs and implemented a firewall cluster based on iptables, managed from FWCloud, which allows unified administration of security policies and ensures greater service continuity. For secure remote access, we configured VPNs based on OpenVPN, centrally managed and with full control over external connections from the same platform, which facilitates access management and unifies policy enforcement.
