Keycloak: Managed Hosting, Installation and Operations
WZ-IT plans, installs and operates Keycloak 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.
Companies worldwide trust WZ-IT
The following are trademarks of their respective owners: Keycloak (Red Hat, Inc.). WZ-IT is an independent service provider and has no business, partnership, or contractual relationship with these companies. We offer independent migration, installation, hosting, and operations services.
About the Technology
What is Keycloak?
Keycloak is an open-source identity and access management (IAM) solution. The platform centralises authentication, single sign-on and authorisation functions for connected applications and APIs.
Keycloak supports OpenID Connect, OAuth 2.0 and SAML as well as connections to directory services and external identity providers. Roles, login flows and the operating architecture are designed for the relevant environment.
Self-Hosted
Architecture
Integration
Managed operations
Ready for Keycloak?
We design, integrate and operate Keycloak for your organisation - on European infrastructure, in your cloud account or on-premises in your own environment.
We provide technical monitoring, backups and maintenance for your Keycloak instance. Human response times and support coverage follow the selected service level.
Operations beyond installation
Operate Keycloak as critical identity infrastructure
When Keycloak fails or is misconfigured, multiple applications are affected. We therefore treat runtime, database, protocols, directories, keys and emergency access as one system.
Protocols and federation
OIDC, OAuth 2.0, SAML, LDAP and external identity providers are integrated in a controlled way.
Policies and applications
Clients, roles, flows, MFA and token content are coordinated with application teams.
Operations and emergency access
Monitoring, backups, updates, key rotation and break-glass access protect operations.
Responsibilities in the identity architecture
We operate the platform and integrate systems; business roles and permissions remain with the customer.
| Area | Responsibility | Scope and boundaries |
|---|---|---|
| Architecture and Keycloak platform | WZ-IT | Sizing and operation of Keycloak, database, proxy and agreed cluster components. |
| Updates and monitoring | WZ-IT | Controlled version changes, technical monitoring and incident handling according to service level. |
| Backups and recovery | WZ-IT | Backup of database, configuration and relevant keys plus scheduled restore checks. |
| Clients and protocol integration | Shared | WZ-IT configures flows and mappings; application teams test login, logout and failure cases. |
| LDAP, AD and identity providers | Shared | Directory access, attributes, groups and synchronisation rules are agreed together. |
| Role and permission model | Customer | The customer owns business roles, approvals and the permissibility of access. |
| Themes, SPIs and custom flows | Optional WZ-IT service | Custom themes, providers and authentication flows can be developed and tested separately. |
Single Sign-On (SSO)
Users authenticate once with Keycloak and automatically have access to all connected applications.
Standard Protocols
Support for OpenID Connect, OAuth 2.0 and SAML 2.0 to connect compatible applications and services.
User Federation
Native integration with LDAP and Active Directory plus support for custom user stores.
Identity Brokering
External identity providers and social login services can be connected through configured broker flows.
Admin Console
Centralized web-based management of all aspects of Keycloak, applications, users, and policies.
Fine-Grained Authorization
Advanced authorization services with role-based and policy-based access control mechanisms.
Account Management
Self-service portal for users to manage their profiles, passwords, and two-factor authentication.
Scalable Deployment
Depending on login load, availability and dependencies, Keycloak can be deployed as a single instance or as part of a cluster architecture.
Customizable & Extensible
Themes for custom designs, extensive APIs and SPI for tailored extensions.

Architecture & Interfaces
Keycloak Development & Integration
Keycloak is modular to the core. Almost every functionality is a replaceable provider. We use Java to implement these SPIs and adapt Keycloak exactly to your infrastructure.
User Storage SPI
The most important point: We don't necessarily migrate your users. We develop User Storage Providers allowing Keycloak to read users directly from your existing SQL DB, mainframe, or API - without duplication.
Event Listener SPI
Audit compliance requires gapless logs. We write Event Listeners that stream every login, error, and admin action to your SIEM (Splunk, ELK, Graylog) in real-time.
Custom Themes (Freemarker)
The standard login window is off-putting. We develop responsive, accessible themes (based on your CI/CD) that seamlessly integrate the login experience into your application.
Concrete Use Cases
How we implement Keycloak development in practice.
Federation with Legacy Systems
Problem
You have thousands of users in an old MySQL database of an EOL software that cannot be migrated.
Solution
A 'read-only' User Storage SPI connects the old DB. Keycloak authenticates against old hashes but issues modern OAuth2/OIDC tokens for new apps.
Passwordless Auth & Magic Links
Problem
B2C customers constantly forget passwords. The login process must be frictionless.
Solution
Implementation of a custom authentication flow that only asks for emails and sends magic links. Fully integrated into Keycloak core, secure, and audited.
Token Enrichment (Mappers)
Problem
Your application needs specific data in the JWT (e.g., tenant ID, cost center) not found in LDAP.
Solution
A Script Mapper (JavaScript) or Protocol Mapper (Java) loads this data from an external API during login and signs it into the access token.
Sizing and deployment
Size Keycloak by login load and dependencies
User count alone says little. Login peaks, token refreshes, client count, federation, sessions and availability targets determine the architecture.
Starting-point guidance
| Usage scenario | Technical starting point | Key factors |
|---|---|---|
| Internal SSO for a few applications | S or M, external database | Suitable for moderate login load and a clearly limited set of clients. |
| Many applications, realms or directories | M or L, separate database | Federation, sessions, token lifetimes and peaks are measured or estimated. |
| Public login or high authentication load | Custom architecture | Load tests, cache behaviour, rate limits and abuse protection are included. |
| Business-critical or highly available IAM | Custom architecture | Cluster, database, keys, upstream IdPs and break-glass procedures must work as one system. |
The calculator is a starting point for a standard instance. HA, load testing, complex federation and multiple environments are designed individually.
Deployment aligned with the trust boundary
Keycloak can run on WZ-IT infrastructure, in your cloud, on-premises or close to distributed applications and directory services in a hybrid design.
WZ-IT managed hosting
Operations on European infrastructure with compute, backup, monitoring and a selectable service level.
Your cloud account
Operations in your cloud with existing network, security and logging services.
On-premises
Integration with your data centre, virtualisation and internal directory services.
Hybrid and multi-site
Secure connection to distributed applications, clouds, LDAP/AD and external identity providers.
Target architecture
Design identity flows across applications and locations
Keycloak connects users, directories and applications. We document trust relationships, token flows, administrative access and failure paths.
Users and applications
Browsers, mobile apps, APIs, service accounts and administrative access.
Secure entry
TLS, reverse proxy, rate limits, network rules and separated administration paths.
Directories and identity providers
LDAP/AD, social or enterprise IdPs plus defined federation and broker flows.
Keycloak platform
Realms, clients, sessions, roles, MFA, flows and token issuance.
Database and cache
Persistent configuration, sessions and, where needed, cluster cache for the target availability.
Clients and APIs
OIDC, OAuth and SAML integrations with tested login, logout and failure paths.
Audit and monitoring
Metrics, events, logs, alerts and optional forwarding to SIEM or central observability.
Identity is a shared dependency. Changes are therefore planned with staging, defined rollback steps and emergency access.
Questions about Keycloak managed hosting
Answers about migration, SSO, high availability and operations.
Yes. We assess version, realms, clients, themes, SPIs, database and connected identity providers, then plan test upgrade, backup, cutover and fallback.
Yes. We integrate applications using the appropriate standard protocol and test login, token refresh, logout, role transfer and failure cases with application teams.
Yes. We design connection, attributes, groups, synchronisation mode and behaviour during outages. The customer defines the business meaning of groups and roles.
When several business-critical applications depend on login and tolerated downtime is low. Keycloak, database, cache, proxy and upstream IdPs must then be considered as one chain.
We assess release notes and extensions, back up relevant data, test critical flows in a suitable environment and plan maintenance windows and rollback steps.
Yes. Themes, user-storage providers, event listeners and other extensions are versioned, tested and included in the upgrade process as separate development services.
This depends on the federation or broker model. We document dependencies and design technical emergency access, monitoring and recovery without bypassing business access controls.

“We have had very good experiences with Mr. Wevelsiep and WZ-IT. The consultation was professional, clearly understandable, and at fair prices. The team not only implemented our requirements but also thought along and proactively. Instead of just processing individual tasks, they provided us with well-founded explanations that strengthened our own understanding. WZ-IT took a lot of pressure off us with their structured approach - that was exactly what we needed and is the reason why we keep coming back. (translated)”

“Timo and Robin from WZ-IT set up a RocketChat server for us - and I couldn't be more satisfied! From the initial consultation to the final implementation, everything was absolutely professional, efficient, and to my complete satisfaction. I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration! (translated)”
