Waldur HomePort Screenshots

Waldur HomePort splits management functionality into workspaces that are used by users in corresponding roles.
Waldur supports management of resources from both public and private cloud providers through a single pane of control.
Оrganization and project teams management is done with invites-based delegations. Allows to maintain full control over access grants while streamlining operations.
Service provider management allows to get an overview as well as manage offering, orders and resources purchased by customers.
Marketplace allows to provision resources from the available service providers that match policy configurations for a particular project. Marketplace offers a common provisioning flow for heterogeneous cloud providers.
Reporting view allow to understand resource usage by customers according to different attributes in a compact and clear view.

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.
