Good IT does not start with tools. It starts with clarity.
Which virtualisation platform is right for your business? What does a migration really cost? And who operates everything afterwards when daily operations take over again? These are the questions that keep IT decision-makers up at night. We answer them honestly, independent of vendors and without any interest in a particular platform. And we accompany you from the first conversation through to ongoing operations, with the same team that was there from the beginning.
Do you recognise this?
Your VMware licence costs have exploded since the Broadcom acquisition and planning certainty has evaporated. Or your virtualisation environment has been running for years, but nobody on the team has the time or the knowledge to operate it properly. Updates get postponed, monitoring has gaps, backups are assumed to work but rarely tested.
Many companies know this feeling. The platform carries the business, but nobody is really carrying the platform.
That is exactly where we come in. Not to sell you a platform, but to understand your specific situation and tell you what genuinely makes sense. Sometimes that is a migration to Proxmox. Sometimes it is professional operation of an existing VMware environment. Sometimes it is something else entirely. We tell you what we see, even when that is uncomfortable.

No platform is right for everyone. We advise you honestly on which one fits your requirements, your existing environment and your budget. Even if the answer is: stay where you are.
First clarity. Then decision.
Then implementation.
We do not start with a proposal but with a conversation. What do you have, what do you need, what is your current path really costing you? We analyse your existing environment, assess technical, economic and compliance requirements and give you a clear recommendation with reasoning.
When the decision has been made, we accompany the entire implementation. Target architecture, HA, storage, network, security, backup and recovery strategy, migration and go-live planning. And afterwards the same team stays by your side that made the decision with you. No handover protocol, no new face that needs to learn everything from scratch.
What we take responsibility for.
With weSystems, you gain a reliable partner that ensures optimal performance and security for your virtual environments.
Consulting and decision clarity
We analyse your existing virtualisation environment, assess costs, risks and migration potential and give you a clear recommendation on which platform fits your business. Vendor-independent and without any interest in a particular solution.
Architecture and planning
Based on your requirements, we develop a target architecture that is stable, scalable and future-proof. High availability clusters, failover concepts, storage design, network architecture and security are integrated from the start, not added as afterthoughts.
Deployment and configuration
We install and configure hypervisors on bare-metal servers, provision VMs to workload requirements, configure virtual networks with VLANs and redundant connections, integrate storage solutions and set up clusters for load balancing and high availability.
Migration and platform change
VMware to Proxmox, Hyper-V to KVM, or another combination. We plan and carry out migrations without disrupting ongoing operations. Live migration, parallel operation of both environments during the transition phase and a clean sign-off before decommissioning the old platform.
24/7 monitoring
We monitor CPU utilisation, memory, storage I/O, network throughput and the health of all VMs and hosts continuously. With Prometheus and Zabbix we identify anomalies early and act before they affect operations.
Patch management and updates
Hypervisors, management platforms and guest operating systems are updated regularly. Updates are validated in test environments, security patches applied with priority and maintenance windows agreed individually with you. No unplanned outages from poorly timed updates.
Backup and disaster recovery
Automated backups, regular snapshots, replication to secondary locations and DR plans that we test regularly. A backup that does not work when it matters is not a backup. That is not a phrase for us, it is lived practice.
Security management
Network segmentation with virtual firewalls and VLANs, role-based access control, MFA for management interfaces, regular vulnerability scans and encryption for data at rest and in transit.
Performance optimization
Continuous analysis of resource utilisation and bottlenecks, dynamic adjustment of VM resources, optimisation of storage I/O and network settings. No wasted resources, no overloaded VMs, no unexplained performance drops.
24/7 support
Our support team is reachable around the clock. For problems we respond quickly, analyse logs and VM states and carry out live migrations in an emergency without downtime for your users. You always speak with someone who knows your environment.
What our customers notice after a few weeks.
Transparency and control
You retain full visibility at all times. Regular reports, proactive communication and a contact who knows your platform because they built it themselves.
Higher availability
High availability clusters, automatic failover and structured backup processes reduce downtime to a minimum. And if something does happen, someone is reachable who already knows your environment.
One team from start to operations
No break between consulting and implementation, no handover to an unknown support team. The same team that planned your architecture operates it too.
No more license surprises
Whether you stay with VMware or switch to an open-source platform, with us you have planning certainty. No unexpected cost increases, no licence models that change overnight.
Vendor independence
With Proxmox, KVM and Apache CloudStack you are not tied to a single vendor. We recommend what genuinely fits and accompany you through a platform change when it makes sense.
Relief for your IT team
Virtualisation operations tie up significant capacity. When we take responsibility, your team has time for tasks that move things forward strategically, without security and stability being sacrificed.
What customers say who have taken this path with us.
We had been debating whether to leave VMware for months. After a single conversation with weSystems we knew what to do, and felt like we had genuinely made the decision ourselves.
IT Manager, mid-sized manufacturing company
Open source in production honestly gave us a queasy feeling. weSystems did not convince us, they informed us. That is a difference you notice in every single meeting with weSystems.
Managing Director, professional services company
I expected them to just sell us Proxmox. Instead they explained why that might not even be the best choice for us. That is exactly why we ended up trusting them with the entire operation.
Head of IT Infrastructure, public sector organisation
Methods are one thing. The team behind them is another.
Understanding virtualisation is not enough. You have to operate it every day, in production environments, under real load, with real consequences when something goes wrong. Our team brings more than seven years of productive Proxmox operation in business-critical environments, alongside years of experience with VMware, KVM, Apache CloudStack and Hyper-V.
We are an authorised Proxmox reseller. We have advised and accompanied mid-sized companies, public sector organisations and enterprises. We know the typical pitfalls in migrations, the points where projects regularly stall, and how to deal with them before they become a problem.
What our customers particularly value: we are directly reachable. Not through escalation levels, not during office hours. When you call us, you speak directly with the architects who know your platform, not a call centre that needs to look things up first.
You can find more about our specific approach to VMware migrations to Proxmox on our Proxmox page.

Frequently Asked Questions
What is Managed Virtualisation?
Managed Virtualisation refers to the professional operation and management of virtualised IT infrastructures by weSystems. We take over consulting, planning, setup, monitoring, maintenance, security and support for your virtualised environments on VMware, Proxmox, Apache CloudStack, KVM and Hyper-V.
Which virtualisation platforms does weSystems support?
We operate VMware ESXi, Proxmox, Apache CloudStack, KVM and Hyper-V in production. The choice of platform depends on your requirements, your existing environment and your budget. We advise you honestly on which option genuinely fits best.
Can weSystems support a migration from VMware to Proxmox?
Yes, that is one of our key areas. We are an authorised Proxmox reseller and have already accompanied several companies through migrations from VMware to Proxmox or Apache CloudStack. We analyse your existing environment, develop a realistic migration strategy and implement it so your systems remain available throughout the entire migration.
Is a switch from VMware to Proxmox worthwhile for us?
That depends on your specific situation. We analyse your existing VMware environment, your requirements and your budget and give you an honest recommendation, even if that recommendation is that a switch does not make sense for you right now. We have no interest in recommending migrations that do not deliver value.
Do I retain control over my virtualised environment?
Yes, completely. We operate your infrastructure, but you retain full visibility and access at all times. What we do is documented and communicated transparently.
How is high availability ensured?
We configure HA clusters with automatic failover so that VMs are automatically moved to other hosts if one host fails. Regular backups, snapshots and DR plans that we test regularly complete the picture.
Is Managed Virtualisation also suitable for smaller companies?
Yes, the service pays off from just a few virtual machines. Smaller IT teams in particular benefit from the relief it provides and from a level of security and stability they could rarely achieve internally to this depth.
Is Managed Virtualisation GDPR-compliant?
Yes. Operations take place in ISO-certified data centers in Germany or in your private infrastructure. All processes are audit-proof and documented. weSystems is itself certified to ISO 27001:2022.
How quickly can Managed Virtualisation be provisioned?
Usually within a few days. After an initial assessment we plan your environment, carry out the migration or setup and start ongoing operations.
What does Managed Virtualisation cost?
Costs depend on the number of VMs, the chosen platform, the desired service level and storage requirements. We are happy to put together a transparent, individual proposal without hidden charges.
