Challo architecture

High level architecture

Challo is a highly available cloud service that provides secure collaboration workspaces.

For an introduction to Challo and its features, see: Challo overview.

Challo has integrations for several applications to provide your members with access to features. The following types of integration are available in Challo:


  • You manage your organization’s members and can invite other people to your tenancy.
  • Challo provides an authentication service; in addition, you can use Google or Microsoft single sign-on services (SSO), to log into Challo.
  • See also: Challo security datasheet—Authentication Security

Cloud storage

  • Your organization can provide its own cloud storage account, for the data you store with Challo.
  • If you configure your own data store, Challo does not store this content; instead Challo connects to your storage account to access the data as your track members require.
  • Challo does maintain meta-data for your tracks; for further details, see: Setting up Challo—Setup your datastore.
  • All of the data that Challo holds, or that Challo stores in your cloud storage account, complies with the processes, encryption, and certification of the Challo security datasheet.

Assistant integration

  • Your organization can designate one of your mailboxes for Challo to connect to operate as a Challo assistant.
  • Challo stores emails on tracks; on the cloud storage you configure.

Collaboration integration

  • Challo provides many integrations to different applications so that your track members can share and access content while using Challo.
  • Organizations manage the integrations that are available to their members.
  • Collaboration integrations are available in the following ways:
    • Across your organization—For example, providing access to documents in your organization’s file storage account.
    • For individuals to manage—For example, someone in your organization can provide access to documents from their own file storage account.
