Mattermost: Managed Hosting, Installation and Operations
WZ-IT plans, installs and operates Mattermost as managed hosting, in your cloud or on premises. Depending on the target design, we also provide migration, secure network and identity integration, monitoring, backups, updates, integrations and further development.
Mattermost is a self-hostable messaging and collaboration platform for organisations that want deliberate control over infrastructure, data location and integrations. Available SSO, compliance and scaling features depend on the selected edition.
As an independent service provider, we support you in installing, configuring, and integrating this powerful communication platform into your existing IT landscape.
TLS-protected transport, controllable data location and configurable access mechanisms. Mattermost does not provide blanket end-to-end encryption for message history.
Structured Communication
Organize conversations in teams, channels, and direct messages for efficient collaboration.
File Sharing & Collaboration
Share files, collaborate on documents, and keep important information at your fingertips.
Extensible Platform
Numerous integrations with development tools, CRM, HR systems, and other business applications.
Compliance & Audit
Depending on the edition, features for audit, retention and compliance exports are available; licensing and specific requirements are assessed separately.
Playbooks & Workflows
Playbooks can structure recurring work and incident processes. Availability and scope depend on the deployed edition.
Operations beyond installation

Infrastructure, integration and operations
Mattermost as part of your infrastructure
We do more than provide an application. WZ-IT designs the technical architecture, integrates network and identity, operates the agreed scope and develops integrations when the standard product is not enough.
Architecture and migration
Sizing, target environment, data transfer, cutover and recovery are resolved before production operations.
On-Premise
In your data center: Installation on bare-metal, VM or Docker · Integration with existing Active Directory/LDAP
Cloud Installation
AWS, Azure, Hetzner & more: Installation on AWS, Azure, GCP, Hetzner · Terraform/IaC setup (optional) · Kubernetes or Docker Compose · Capacity and scaling design
Take over an existing Mattermost environment
We assess your existing Mattermost environment, plan the target architecture and safeguard the transition with backups and a rollback option.
Enterprise Setup

Personal technical contact
Integration and development
APIs, automation and custom extensions can be delivered beyond basic deployment.
REST API v4 & Drivers
Mattermost offers one of the most comprehensive APIs in the open-source space. We use the official Go and JavaScript drivers for seamless integrations - automatic channel creation from your CRM, user management via LDAP sync, or bidirectional data synchronization with your ERP.
Webhooks & Slash Commands
For quick integrations, we use incoming/outgoing webhooks. Messages from monitoring tools (Prometheus, Grafana) land directly in channels. Actions like server restarts or deployments can be triggered via slash commands (/deploy production) directly from chat.
Plugin Architecture (Go & React)
When webhooks aren't enough, we develop native plugins. These run directly on the server (Go backend) and in the client (React frontend). This allows us to modify the UI, add buttons to the message bar, or implement deep logic with database access.

Concrete Use Cases
Mattermost Development & Integration
Mattermost follows a consistent API-first approach. Every action you perform in the UI runs through the same API we use. This makes integrations predictable and stable.
ChatOps Automation
Problem
DevOps teams need to switch between terminal and chat for routine tasks. Checking server status, triggering deployments, or retrieving logs requires context switching.
Solution
We develop slash commands and bots that work directly in chat. /deploy production rolls out, /status shows server metrics, /logs api-server streams the latest entries. All without leaving chat.
CRM Bridge & Sales Alerts
Problem
Sales reps maintain data twice - in CRM and team chat. Updates on deals, contacts, or tasks get lost.
Solution
Middleware synchronizes your CRM (HubSpot, Salesforce, Twenty) with Mattermost. On contract close, a bot automatically posts to the sales channel. Contact cards can be retrieved via /contact [name].
Incident Response Bot
Problem
Alerts from monitoring systems (Prometheus, Grafana, Wazuh) end up in emails or separate dashboards. Response time suffers.
Solution
An incident bot receives alerts via webhook, automatically creates a dedicated channel, invites relevant team members, and posts context (logs, metrics). Playbooks are started automatically.

Answers about editions, migration, integration and operations.
No. The displayed price describes WZ-IT infrastructure and operations. If required features need a paid Mattermost edition, the vendor licence is quoted separately.
Yes, after assessing available exports, users, files, integrations and the target edition. We plan a test migration, cutover and fallback.
We support technical integration with existing identity providers. The available method and provisioning features depend on the selected Mattermost edition and are checked in advance.
Not by default. Calls create a separate load and network profile. We size and price the required components from concurrent participants and the target topology.
Yes. Application, database, storage, proxy, search and, where relevant, Calls and push need to be designed together. Vendor features and licences are included in the assessment.
Yes. We integrate webhooks and existing tools or develop bots, plugins and middleware for DevOps, incident and business processes.
Depending on the setup, we back up database, file storage and configuration consistently. Retention and recovery objectives are agreed; isolated backup files alone are not a complete restore plan.
Yes. We support roles, teams, channels, permissions and the technical rollout. Training and change-management services are agreed according to the project scope.
Yes. Critical changes can use a separate staging environment with a defined approval and rollback process. Whether this needs additional workloads depends on the architecture and data volume.
We review release notes, edition and extensions, protect the relevant data and perform updates in agreed maintenance windows. Major upgrades can be tested in staging first.
Typical signals include availability, resources, database, file storage, queues, search components and backup jobs. Monitoring and retention are limited so message content is not collected unnecessarily.
We integrate official clients, push services and available MFA or SSO methods. Which functions work without external services or extra licences is checked for the selected edition.
Mattermost is a self-hostable communications platform with channels, direct messages, files and integrations. Community and paid editions differ for some identity, compliance and clustering functions; we verify the required edition before planning.
It can run on WZ-IT infrastructure, in your cloud account, on premises or in a hybrid setup with internal services. Network, data location, access paths and operating responsibilities are defined in the target design.
For new production environments we design the database supported by the selected Mattermost version together with file or object storage, search and backups. Existing MySQL installations are assessed separately before takeover.
The agreed scope can include provisioning, baseline hardening, monitoring, backups, updates, incident handling and planned scaling. The service description and selected service level are binding, not the label by itself.
Active users, message load, uploads, search, integrations, Calls, retention and availability targets determine compute, database, storage and whether a distributed architecture is needed.
We design separated roles, MFA or SSO, private administration paths, logging and break-glass procedures. The implementation depends on edition, identity provider and the existing network architecture.
Audit, export and retention functions partly depend on the selected edition. We configure technically available controls; the customer defines legal retention and deletion rules and the permissibility of content.
Yes. We integrate available Playbooks, incoming and outgoing webhooks, slash commands and Git, CI/CD, monitoring or ticket systems. Availability and licence requirements are checked for each integration.
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.
