Architecture and migration
Sizing, target environment, data transfer, cutover and recovery are resolved before production operations.

WZ-IT plans, installs and operates Postgres 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.
The following are trademarks of their respective owners: PostgreSQL (the PostgreSQL Global Development Group). 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.

PostgreSQL is an object-relational open-source database system for transactional applications, data platforms and custom extensions. Availability and performance depend on schema, queries, workload and operating architecture.
We support PostgreSQL design, implementation, migration, optimisation and maintenance, including replication, backup, restore testing and monitoring.
We install, host and operate PostgreSQL for your company - either on our secure, privacy-focused infrastructure in Germany or other locations, as well as on-premise in your own environment.
We provide 24/7 monitoring, backups and maintenance for your PostgreSQL instance. Human response times and support coverage follow the selected service level.
Designed for maximum data safety and integrity with robust crash recovery mechanisms, write-ahead logging, and point-in-time recovery.
Supports the ACID properties of atomicity, consistency, isolation and durability for transactional applications.
Implements the SQL standard with numerous extensions such as common table expressions, window functions, and materialized views.
Offers native support for JSON/JSONB data types and enables the combination of relational and document-oriented data storage.
Leverage the extensive ecosystem of extensions such as PostGIS for spatial data, TimescaleDB for time series data, or pgVector for AI applications.
Streaming replication, logical replication, and multi-master solutions enable highly available and geographically distributed systems.
Powerful indexing options, parallel query processing, and sophisticated query optimization for fast data operations.
Provides row-level security, advanced authentication methods, SSL support, and detailed access controls.
Benefit from a rich ecosystem of tools for administration, monitoring, backup, and migration, as well as numerous client libraries.
Professional installation on your infrastructure - on-premise, cloud or hybrid
In your data center
AWS, Azure, Hetzner & more
Advanced architecture after technical and licence assessment
Secure access and access control for your installation
WireGuard, NetBird or Tailscale
Directly or through an upstream identity layer
Depends on application, edition and identity provider
Fail2Ban, Rate Limiting, IP Whitelisting
We set up secure VPN access to your installation - ideal for remote work and external employees.
Full-service installation with no hidden costs
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.
Sizing, target environment, data transfer, cutover and recovery are resolved before production operations.
SSO, secure access, internal systems and existing security components are integrated appropriately.
Updates, backups, technical monitoring and response paths follow a transparent operational scope.
APIs, automation and custom extensions can be delivered beyond basic deployment.
The exact scope depends on the application, edition, infrastructure and criticality. Vendor licences and non-standard components are quoted separately.
Data platforms are designed around access patterns, consistency, growth, recovery and the applications that depend on them.
Defined clients, services and ingestion processes connect through private or secured interfaces.
TLS, firewall rules, reverse proxies or private network paths are designed around the platform's exposure.
Local accounts, SSO, directories, service accounts and emergency access are connected through clear roles.
Queries, indexes, roles, resource limits and maintenance processes are configured for the workload.
Storage class, capacity, latency and growth aligned with the data profile.
Optional cluster, replica or failover design according to the required protection objective.
Consistent backups, retention and scheduled restore checks.
The diagram is a resilient target model. Its implementation depends on edition, data flows, load, availability objectives and existing infrastructure.
A clearly defined operating scope instead of an opaque hosting flat fee.
We set up a test instance for you, usually on the next business day. No payment details required. After seven days it is deleted unless you continue.
Compute, applications, storage and response are shown separately. You can see what ongoing operations include and which requirements need a technical assessment.
We also design custom PostgreSQL architectures, integrations and migrations. Contact us for a technical assessment.
One managed standard PostgreSQL application is included in the Starter workload. Every service level also includes flexible expert time for planned work during regular service hours. Select compute, additional applications, storage and the appropriate service level.
A workload is one compute instance with the applications agreed for it.
One standard app per workload is already included. Additional dedicated servers count as separate workloads.
€79.90 per started TB and month, including daily encrypted offsite backup with 7-day retention.
Briefly describe the current state and objective for PostgreSQL. We assess infrastructure, integration, and ongoing operations.
Whether you run PostgreSQL in-house or need to host confidentiality-professional data §203-ready - we build, operate and maintain PostgreSQL on an encrypted on-site server. Data never leaves the building in cleartext.

We size PostgreSQL clusters based on workload profiles, recovery objectives, availability requirements and measurable performance targets. Architecture and operating scope are defined for the specific application.
Designed for the agreed availability target
These solutions are often used together with PostgreSQL
These solutions offer similar functionalities and can be evaluated together
These solutions are direct alternatives with similar use cases
No risk: worst case, you leave with a clearer understanding of your project than before.


“WZ-IT's advice on our Azure migration was technically sound and completely non-binding right from the intro call - we took away a great deal.”
Whether a specific IT challenge or just an idea - we look forward to the exchange. In a brief conversation, we'll evaluate together if and how your project fits with WZ-IT.
