Contracted operations
Linux server management for ongoing operations
Linux server management combines maintenance, monitoring, backup checks, and the agreed response path. Patch cycles, maintenance windows, and responsibility boundaries are defined in the service schedule.
Linux server maintenance with clear responsibilities
Patch cycles, maintenance windows, backup checks, and responsibilities are recorded in the service schedule. Standard management of an existing Linux server starts at €149.90 net per month.
Security updates need a defined process
Without ownership, maintenance windows, and an approval process, available security updates are easily delayed. A maintenance plan defines how updates are assessed, tested, applied, and documented.
One-off assignments are difficult to plan
When maintenance is commissioned only as needed, scope, timing, and availability must be agreed each time. An ongoing maintenance scope creates a fixed cadence and a predictable basis.
Responsibilities must be documented
Patching, backup checks, monitoring, and incident response are different tasks. The service schedule records which responsibilities WZ-IT assumes and which remain with the customer or another provider.
What Linux Server Maintenance Includes
Six building blocks that together form server maintenance - from patch cycle to report.
Monthly Patch Cycles
Fixed monthly maintenance cycles for OS and package updates on your Linux servers. Critical security updates do not wait for the cycle - they are applied promptly.
Planned Dist Upgrades
Major upgrades (e.g. Debian, Ubuntu LTS) are planned ahead: testing, a coordinated maintenance window and a rollback strategy - instead of an upgrade backlog until end-of-life.
Monitoring incl. Response
We proactively monitor your servers around the clock and respond to relevant alerts within the agreed response time.
Backup Checks & Agreed Restore Tests
We monitor the agreed backup jobs and retention. Restore tests, test frequency and RTO/RPO are explicitly defined in the recovery scope for the environment.
Maintenance Windows & Change Docs
Changes happen in coordinated maintenance windows - not in the middle of daily business. Every change is documented: what was changed when, why and with what result.
Patch Reports & Recommendations
After each maintenance cycle you receive a report: applied patches, handled alerts, backup status and concrete recommendations for the next steps.
Monitoring, Server Management, and Service Levels
Monitoring only ends with alerting your team. Linux server management includes maintenance and an agreed response; service levels define the coverage window.
Monitoring only
from €79.90 / month
We monitor the agreed systems and send alerts to your team. Technical response and incident resolution remain your responsibility.

How Your Maintenance Contract Goes Live
Four steps from the first look at the systems to the ongoing maintenance cadence.
- 01
Server Audit
We assess the current state of your servers: update status, security, backups and monitoring gaps - documented and prioritized.
More about the server audit - 02
Maintenance Plan & SLA
The audit results in the maintenance plan: patch cadence, maintenance windows, backup strategy and response times - bindingly defined in the SLA.
- 03
Service Start
Monitoring, access, and responsibilities are established and documented - ongoing operations then begin.
- 04
Ongoing Cycles with Reports
Monthly maintenance cycles, prompt security updates and regular patch reports - you always see what happens on your servers.

Linux Server Maintenance vs. Ad-hoc Support
Ad-hoc support repairs what is already broken. A maintenance contract makes sure it does not get that far in the first place - with a fixed cadence, clear responsibility and calculable costs.
| Maintenance contract (WZ-IT) | Ad-hoc support | |
|---|---|---|
| Response | Defined response times per SLA - alerts land directly with our team | Response when someone happens to have time - often only after the outage |
| Predictability | Fixed maintenance windows and monthly patch cycles | Intervention only when something breaks - updates pile up |
| Cost structure | Calculable monthly fee, transparent in the initial consultation | Open hourly rates per incident - emergencies get expensive |
| Responsibility | Contractually defined: patching, backups and monitoring sit with us | Effectively stays with you - the provider works on demand |
| Documentation | Change docs, patch reports and maintained operations documentation | Rare - knowledge stays in heads and ticket histories |

Frequently Asked Questions
Answers to the most important questions
Yes. WZ-IT provides ongoing Linux server management with OS and security updates, coordinated maintenance windows, monitoring with response, backup checks, and operations documentation. The standard entry point starts at €149.90 net per month.
At WZ-IT, both terms lead to the same ongoing operations service. Maintenance describes updates and planned work in particular; server management is the umbrella term for the agreed overall scope, including monitoring and response.
Standard management of an existing Linux server starts at €149.90 net per month. Progressive volume pricing applies to further servers in one coherent customer environment. Criticality and the selected service level can increase the price; complex platforms and non-standard applications are quoted after the infrastructure audit. You continue to pay the hardware provider directly.
Debian, Ubuntu and RHEL derivatives such as AlmaLinux and Rocky Linux are our daily business. We also take older systems (e.g. CentOS 7 or Ubuntu 18.04) into maintenance - including hardening the current state and a joint plan for the dist upgrade to a supported version.
The standard is a monthly maintenance cycle with a fixed maintenance window for OS and package updates. Critical security updates do not wait for the cycle - they are applied promptly. We adapt the cadence to your environment, for example for systems with their own release processes or tight operating hours.
We handle critical vulnerabilities outside the regular cycle: we assess whether your systems are affected, apply the patch promptly or implement a workaround if no patch is available yet. Afterwards you receive a short note on what was done and why.
Yes, within the agreed service level. Monitoring runs around the clock. For P1 incidents, Production provides 24/7 response within 60 minutes and Critical within 30 minutes including callback. Essential, Business and Priority use defined service windows. The SLA and service schedule define what qualifies as P1.
No. Your servers stay where they are: with your provider, in your account and under your contract. For maintenance we only need administrative access (SSH key, technical user). There is no forced migration and no vendor lock-in - you retain full commercial and technical control.
The term and notice period are stated clearly in the offer and contract. Servers and provider contracts remain with you; access credentials and the operations documentation owed under the agreement are handed over in an orderly manner at the end of the contract. This keeps a future change of operator technically manageable.
Operations that visibly relieve customers
Customer feedback on monitoring, updates, maintenance, support and stable production systems.
“WZ-IT moved our studio infrastructure from decentralised individual devices to a central platform: every site is securely connected via VPN, new devices are onboarded automatically and an entire site is provisioned from a template, without manual steps on location. What impressed me most is the breadth and depth of their knowledge: Timo and Robin are not a typical IT provider who sets up a server and leaves. The two of them think their way into highly complex infrastructure and software topics, work through every requirement we put in front of them, and build networking, provisioning and operations so that everything fits together in the end. WZ-IT is an excellent partner for complex software, network and architecture projects.”
Steve Kirchner
Managing Director, nextGYM GmbH
“Professional, honest and technically thoroughly sound: WZ-IT set up our Proxmox and backup infrastructure securely and future-proof. The consulting from Timo and Robin was objective and needs-driven, the implementation smooth and the final documentation exemplary. You can tell immediately that business-critical infrastructure is thought through holistically from the outset here and implemented with clear ownership.”
Pascal Block
Project Manager, Stadtwerke Brühl GmbH
Stadtwerke Brühl - municipal energy and infrastructure utility.
“WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”

“Communication with WZ-IT was open, friendly and professional from the very beginning. Mr. Wevelsiep and Mr. Zins responded to every one of our questions patiently, promptly and respectfully, and contributed their own suggestions and good ideas on how to modernize our server infrastructure and adapt it even better to our needs. Throughout, WZ-IT consistently kept our need for data sovereignty and GDPR compliance in mind. Even short-notice adjustments and change requests from our side were implemented quickly and patiently and integrated consistently into the overall concept. From planning to the final handover, every step was documented transparently and comprehensively - so if a provider change should ever become necessary, the documentation would let us onboard a successor into our infrastructure very quickly. We are extremely satisfied with WZ-IT and hope to continue working together for a long time.”
