Overview

Service marketplace

Providers publish offerings with price plans. Customers order them, with optional approval by the project, organization or provider.

Self-service portal

One portal with separate workspaces for end users, service providers and staff. Users sign in with their institutional or national identity.

Reports and dashboards

Usage, cost, revenue and capacity reports for staff, providers and organization owners, all exportable. Metrics can also be sent to Prometheus and Grafana.

Accounting and billing

Fixed-price, usage-based, one-time and limit-based pricing, with automatic invoices or export to external billing systems.

Service desk

Built-in support tickets, or a connection to Jira Service Management, Zammad or OpenText SMAX, so customers have one support line for every service.

Open source

MIT-licensed. Deploy with Helm or Docker Compose, on premises or in the cloud, with professional support available.

Teams, projects and roles

Customers invite people into projects, delegate resource management with role-based access and let roles expire automatically. Every change is recorded in an audit log.

Policies and budgets

Set cost and usage limits per organization, project or offering. When a limit is reached, Waldur notifies the team, blocks new orders or requests downscaling.

Calls for proposals

Hand out resources through calls: application forms, review rounds, conflict-of-interest checks and allocation decisions. Accepted proposals become projects with the awarded resources.

AI assistant

A built-in assistant helps users in plain language: finding open calls, preparing proposals, managing resources and finding their way around the portal.

Project chat on Matrix

Every project gets an end-to-end encrypted Matrix room. Members join automatically based on their roles, and a Waldur bot answers questions about status, orders and members and opens support tickets from the chat.

Automation and APIs

Everything in the portal is available through the REST API, with a Terraform provider, an Ansible collection and SDKs for Python and TypeScript.

Credentials stay with the provider

Providers can connect their systems through the Waldur Site Agent, which runs on their side and keeps infrastructure credentials there.

Federation

Independent Waldur deployments can share offerings, so partners use each other’s services while each keeps its own governance.

How it works

Waldur MasterMind cloud orchestrator exposes REST API service that enables end-customers to access Marketplace, organization, project and resource management functionality. MasterMind comes with advanced Admin Portal interface for operator-only use.

MasterMind is highly modular. Modules are divided into Core, AuthN, Value-add and Provider groups. For example, Core modules deal with standardized global objects while Provider modules map and handle backend specifics. Core functionality can be extended and customized further with Value-add modules and identity providers are fully pluggable.

Provider modules allow to integrate and connect with in-house infrastructure orchestrators, existing systems and public cloud endpoints.

Waldur HomePort is a state-of-the-art Self-Service Portal targeted at the end customers. It is built as ReactJS application and communicates with MasterMind API service directly from a browser. It provides a graphical user interface for Marketplace catalogue, dashboards, resource management and much more.

HomePort includes Helpdesk functionality for convenient interaction with operator's support team.
