openbook #3

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

  • 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

  • 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.
