Project in numbers
VMware has discontinued the option of using its software for free, which has significantly increased costs. Since Proxmox still offers a free version that meets Bitset's needs, we eliminated licensing costs by switching virtualization platforms.
System downtime was minimal due to the provisioning of a replacement virtual environment. Each server was temporarily shut down for less than an hour.
With the transition to Proxmox, the use of templates, and automation, we have simplified virtual server management. The process is now up to 50 % faster than in the VMware environment, with greater efficiency and fewer errors.
Challenge
Precise migration planning for uninterrupted business operations
The key challenge in the transition from VMware to Proxmox, two leading platforms for server virtualization, was to ensure minimal downtime, as it is important for the company that the back-end servers operate continuously.
Establishing an alternate environment for uninterrupted server migration
To ensure seamless availability and uninterrupted operations during the migration, we set up an alternate virtual environment for Bitset, to which we successfully migrated the key servers. This step enabled the systems to run in real time even during the complex infrastructure reconfiguration, ensuring a smooth transition without service interruption.
Backup update for reliable data protection
We carried out a comprehensive overhaul of the backup system using the Veeam solution. We set up a two-tier system: the primary tier of backups runs locally on Bitset's infrastructure, and the secondary at a remote location within our own server infrastructure.
- A Backups of critical data
- B Primary location: Humanfrog's data centers
- C Secondary locations
- D The entire system ensures communication with online and physical stores where Bitset sells computer equipment - across Europe
3-2-1
The system is designed according to the 3-2-1 principle, which means at least three copies of data, stored in two different types of locations, one of which is physically separate (off-site). In this way, as one of the largest regional cloud providers, we ensure complete control over data, secure application integration, and reliable and secure communication with external services.
Results
For Bitset, we carried out a transition from VMware to Proxmox while ensuring uninterrupted operation of the critical infrastructure. By establishing an alternate virtual environment and upgrading the backup system, we enabled a smooth migration with less than one hour of downtime per server. The transition to Proxmox also brought the complete elimination of virtualization platform costs and long-term savings, as the free version fully meets Bitset’s needs.
