SaaS Accelerator licensing
SaaS Accelerator is a service, and the license defines the parameters of the service. A SaaS Accelerator license applies to an SAM organization for a specific time period and is defined by these characteristics:
SaaS applications | Minimum/maximum number of users | AppUnits per user | Connections per user |
Box | 400 – 100,000 | 5 | 5 connections |
Microsoft Office 365 | 200 – 50,000 | 10 | 10 connections |
Microsoft Teams and Stream Live Event (video only) | 200 – 50,000 | 10 | N/A |
Microsoft Dynamics CRM | 200 – 50,000 | 20 | 10 connections |
Salesforce | 200 – 50,000 | 10 | 10 connections |
ServiceNow | 200 – 50,000 | 10 | 10 connections |
Veeva | 200 – 50,000 | 20 | 10 connections |
• AppUnits - This component defines how many users can accelerate SaaS traffic for an application. You specify the number of users to support when you configure acceleration for an application. The number of users allowed is determined based on the number of available AppUnits, as well as the minimum and maximum number supported by the application. When configured, SAM allocates the AppUnits to the application.
AppUnits provide flexibility so you can easily change which applications to accelerate, or resize your configuration based on usage. As you configure SaaS acceleration in SAM, tooltips provide recommendations specific to each application.
• AppData - This component defines the amount of egress data (in GiB) allowed through the SaaS service cluster. You can track the total amount of data used and data usage trends per application on the SaaS Accelerator Cumulative Egress Data Usage page (choose Reports > Data Usage).
Each AppUnit includes 0.3 GiB of AppData. For example, if you buy 10,000 AppUnits, you can deploy 1000 users for Office 365, and you would get a total of 3000 GiB per month for those users. With a yearly subscription, that provides a pool of 36,000 GiB (12 months x 3000 GiB per month).
AppData is pooled for all applications and all users. AppData allows monthly carryovers through the end of the subscription, providing flexibility for usage variations.
You can purchase additional AppUnits or AppData through add-on licenses.
The SaaS Accelerator license is specific to your SAM organization, not per client-side appliance. You can register any number of client-side appliances in your organization with SAM managing the SaaS Accelerator service.
Before you activate SaaS Accelerator on a client-side appliance, ensure that you account for the added connection and throughput usage in the same way you would when introducing any other additional application for optimization on the appliance. Registering a client-side appliance with the SaaS Accelerator service does not change the optimized session limit for that appliance.
User and data limits are enforced based on the available license.
SaaS Accelerator service cluster limits
The SaaS service cluster has the following deployment characteristics:
• A SaaS service cluster for any application can handle a maximum of 500,000 connections.
• The minimum size of the service cluster depends on the license. The minimum license is 2000 AppUnits.
• SaaS service clusters deployed in different SAM organizations are independent of each other.
• Each SAM organization can deploy only one cluster per SaaS application.
SaaS Accelerator connection and user limits
SaaS Accelerator lets individual users consume more TCP connections per user than those allocated, but does not allow the total number of TCP connections for the SaaS acceleration cluster to exceed the limit. If you exceed the total number of available connections for the cluster, or if the number of active users is significantly higher than the configured value, SaaS Accelerator enters admission control and new connections matching the SaaS application defined in the client-side appliance in-path rule will not be accelerated.
For Microsoft Teams and Microsoft Stream, you will see a notice in the SaaS Accelerator user interface and your SaaS Accelerator administrator will receive an email if you exceed the usage limits provided by your license.
