Cluster Systems
High availability. Without compromise.
Cluster systems help critical server, storage and infrastructure components remain available even during disruptions. We plan and support robust environments that reduce downtime and protect your business processes.
✓ Server & storage
✓ Redundancy & failover
✓ Monitoring & operation
Services
What we provide for cluster systems.
Cluster systems must be planned carefully. The key factors are suitable hardware, storage, networking, virtualization, monitoring, backup and a clear understanding of which systems are truly business-critical.
Server clusters
We plan and support server environments that keep services available even when hardware problems occur.
Storage concepts
We include high-performance and redundant storage solutions as the foundation of stable cluster infrastructures.
Network & redundancy
We plan network paths, connections and components so individual failures can be handled more effectively.
Virtualization
We combine cluster concepts with virtualized environments for flexible and maintainable IT structures.
Monitoring & operation
We support monitoring, maintenance and early detection of critical conditions.
Emergency readiness
We include recovery, backup and failure scenarios to make critical systems more resilient.

Why cluster systems with büKOM Systemhaus GmbH?
High availability only makes sense when it fits the environment, risk and budget. We provide honest consulting, clean planning and combine cluster technology with backup, networking, virtualization and ongoing support.
✓ Less downtime for critical systems
✓ Clean connection of server, storage, network and backup
✓ Concepts aligned with risk, budget and company size
✓ Support from planning to ongoing operation
✓ Regional support in Ladenburg, Mannheim, Heidelberg and Rhine-Neckar
Process
Our process.
We start by identifying which systems truly need protection. Then we plan a solution that is technically resilient and economically sensible.
1
Clarify requirements
We identify critical services, risks, availability requirements and existing infrastructure.
2
Create concept
We plan cluster architecture, hardware, storage, network, backup and operation.
3
Implementation
We set up the environment, test failover scenarios and document the solution.
4
Secure operation
We support maintenance, monitoring, adjustments and further development.
Should your critical systems become more fail-safe?
Let us review which cluster solution makes sense for your server, storage or infrastructure environment.
Benefits
What a cluster solves.
A cluster distributes operation across several nodes. If one fails, the others take over. The goal is not more performance, but less dependence on a single device.
✓ The failure of one host does not bring all systems to a standstill
✓ Maintenance and updates are possible during operation because systems can be moved
✓ Planned hardware replacements can be carried out without extended downtime
✓ Redundant network and storage connections reduce further single points of failure
Limitations
What a cluster does not replace.
High availability protects against hardware failure — not against errors that are replicated correctly. This distinction is the most common misconception in cluster projects.
✓ No substitute for backup: deleted or encrypted data is deleted on all nodes. A cluster reliably replicates the error too — see Backup & Recovery.
✓ No substitute for security: an attacker with valid credentials can also reach the redundant environment.
✓ No substitute for monitoring: if a node fails unnoticed, the cluster keeps running without a reserve — until the next one fails.
✓ No substitute for documentation: in an emergency, it must be clear how a failover is supposed to work.
✓ Where simple flexibility rather than redundancy is needed, virtualisation without a cluster is usually sufficient.
Frequently asked questions
For which companies is a cluster system worthwhile?
Whenever downtime has a noticeable business impact, for example for central applications, databases or virtualised environments. Together we assess whether the effort pays off for your company.
What happens in a cluster when a server fails?
If a node fails, the remaining servers automatically take over the load. Services continue to run with no or minimal interruption while the failed node is repaired.
How much effort does it take to run a cluster system?
With a well-planned setup, the ongoing effort is manageable. We take care of monitoring, updates and maintenance so that your cluster remains stable and performs well over the long term.
Which technologies does büKOM use for cluster systems?
Depending on the requirements, we work with Proxmox- and VMware-based cluster environments, among others, and adapt the architecture to the existing infrastructure and budget.
