openbook #5

Supports: trusty
Add to new model


Openbook by Talligent is cloud management software that simplifies the tasks of planning, charging, and predicting capacity requirements for cloud services. Talligent gives the administrator and tenant real-time visibility of resources and accrued costs, as well as the ability to scale up or down according to budget and resource requirements. The Openbook Billing Engine offers a sophisticated cloud billing platform, with granular rate plans for various personas of tenants and usage patterns, supporting billing, chargeback or showback for private or public clouds. Resellers experience the same range of flexibility as the root cloud owner. Invoice and cost accounting information can easily be shared with CRM and accounting packages via Rest-based APIs.


Openbook reliably solves the customer lifecycle of onboarding, self-service, and cloud billing or charge-back with minimal manual intervention. Whether you are a service provider billing customers for cloud services, or an enterprise needing showback and tenant self-service, Talligent delivers a fully-functional, simple to use cloud management solution that has been built specifically for OpenStack.

Enterprise adoption of OpenStack is growing quickly, driven by the interest in providing on-demand cloud services behind the firewall. Private cloud deployments increase the agility of IT departments to respond to infrastructure requests, increase control of company digital assets, and reduce the need for shadow IT services from public cloud providers. In response to this increase in market demand, Talligent has added functionality to support private cloud use cases such as chargeback, utilization tracking for sprawl control, single pane of glass view of hybrid clouds, and capacity reporting to improve resource and budget planning of cloud growth.


About Talligent Openbook

Talligent delivers a fully-functional, simple to use cloud management solution that has been built specifically for OpenStack. The functionality is designed to support public or private cloud deployments; billing, chargeback or showback reporting; and direct to customer or reseller channels. Users can register new accounts, manage users at the project level, view unbilled charges and past invoices, and pay their bill all through the Openbook interface. Key features of the Openbook tenant lifecycle solution include:

For the Enterprise private cloud:

  • On Demand Cloud Infrastructure: Openbook enables enterprises to provide on demand cloud services based on the OpenStack platform. This includes dedicated instances, networks, storage, applications, virtual desktops, and other infrastructure elements or services.

  • Capacity Planning: Without visibility into the growth of cloud services by department, it is impossible to accurately predict how much new capacity to add, and when. Detailed reports of growth trends and seasonal patterns allow you to better plan for new capacity. Forecasts of the cost of cloud projects is coming soon.

  • Single Solution: We do OpenStack well but also know that you have other services to account for. Our RestAPI allows you to push additional infrastructure elements into Openbook for inclusion into the rate plans. A VMware adapter allows you to compare costs across your private hybrid cloud environment. All cost information can be easily shared with legacy accounting systems for detailed budget planning.

  • KPIs: Quickly answer key management questions about your environment – largest tenants, service growth, and accrued costs. Ad hoc reporting allows you to drill down to the relevant details of your cloud environment

  • Showback/Chargeback: Openbook has a robust ratings engine tuned to OpenStack and VMware clouds. Costs can be assigned by tenant, business unit, VP, project, or other cost center. Managers are automatically updated on their accrued costs as well as performance against budget

  • Sprawl Control: Reduce VM sprawl and help your internal users be better stewards of the environment by giving them the visibility and tools to control resources assigned to them. Openbook tracks orphaned entities and underutilized instances to keep your cloud clean.

For Service Providers:

  • Simple to Deploy: No custom coding and integration is required for Openbook to take full advantage of the power and flexibility of OpenStack. You can be up and running in just a few minutes without engaging expensive developers or OpenStack resources

  • Sell On Demand Cloud Infrastructure: Openbook enables you to sell the cloud services you want and customers demand. This includes dedicated instances, networks, storage, applications, virtual desktops, and other infrastructure elements or services. Services can be packaged by tiers, metered and sold by the hour, delivered on-site or as part of a shared infrastructure.

  • Customer Self Service: Talligent self-service means that customers can log into the portal at any time and view the resources they have provisioned, costs accrued to date, past and present invoices, payment status and account details. Customers can make quota change requests to align resources with billing and project needs. Workflow is automatically routed to the admin for processing, eliminating ticketing and speeding responses.

  • Reseller Workflow: Cloud service providers can expand their customer reach and strengthen their existing relationship via resellers. Openbook natively supports reseller workflow with corresponding rate plans that support taxation, currency conversion, proration, discounts, and promotional codes independent from the master service provider.

  • Customize and Brand: Openbook is a full white label solution. Service providers can change the look and feel of the solution to support their brand. Resellers likewise can independently customize the look and feel of the interface and customer communications.

The Openbook charm requires a database (Mariadb) and an Application server (Apache Tomcat) to function properly. The mysql and tomcat7 charms already have the installation and configuration done for you.

Use the following steps to set up Openbook:

juju deploy mariadb
juju deploy tomcat
juju set tomcat https_enabled=True
juju deploy openbook
juju add-relation openbook tomcat *(This step installs Openbook in Tomcat)*
juju add-relation openbook mariadb  *(This step creates the openbook database)*
juju expose tomcat

Openbook requires a database connection and will remain undeployed until the relation to Mariadb exists. If it the relation is removed or destroyed Tomcat will be shutdown, Openbook will be undeployed and the charm will wait for a new datbase connection.

It is important to wait for Openbook and Tomcat to finish starting before accessing the web site. Use the juju status command to see the status of the deployments and to copy the IP address and http port of Tomcat.

After the Openbook charm is deployed and related you can go to the Openbook web page at: https://IP_ADDRESS:8443/Openbook/ Where IP_ADDRESS is the public address of the tomcat container and can be found by typing juju status tomcat.

The initial username and password is openbook/Tall!g3nt. Please refer to the Openbook installation guide for more details on how to get started with Openbook.

Scale out Usage

For high availability, we recommend a standard two-tier web-app redundant configuration.
