ArcGIS Velocity allows you to create, share, and manage real-time and big data ingestion and analysis tasks, which are processing (computing) tasks. Analytics can also write output to feature layers, which are hosted and stored in a spatiotemporal big data store. Each ArcGIS Velocity license level includes a given amount of compute capacity and storage capacity.
Compute, or processing, is managed by the number of running feeds and analytics for a Standard or Advanced license and by overall compute capacity for the Dedicated license.
Running items (Standard or Advanced license)
In the Standard or Advanced license, your organization can run up to a maximum number of feeds and analytics at the same time. This can be any combination of items depending on the needs of the use case. The Standard license supports up to ten running items, so this can be four feeds, four real-time analytics, and two big data analytics; or four feeds, three real-time analytics and three big data analytics; and so on.
The number of running items (feeds and analytics) that can be supported in the Velocity Advanced subscription can be augmented with additional item units. An Item Unit is a pack of five items (again, feeds and analytics) that can be running the same time. For example, if one additional item unit is added to the Advanced subscription, the maximum number of running items will be increased from 15 to 20 items.
Administrators can view the number of running items on the Home page in the Velocity application. Additionally, the Feeds and Analytics page reports the list of feeds, real-time analytics, and big data analytics that are actively running. For details, see Compute and storage management.
Compute (Dedicated license)
In the Dedicated license, an ArcGIS Velocity subscription is a dedicated real-time and big data processing system with a given amount of compute.
Each running feed or analytic consumes compute resources, and this consumption varies by data characteristics, velocity, and volume. See the following examples:
- Feeds ingesting tens of thousands of observations per second will consume more compute capacity than feeds that support lower velocities.
- Real-time analytics support autoscaling, which means that if their initial compute profile does not accommodate the incoming velocity or volume of data, the analytic will be incrementally scaled until the workflow can be sustained. Real-time analytics processing higher velocity data will therefore consume more compute capacity than analytics processing lower velocity data streams.
- Big data analytics can be configured with different run settings based on the volume of data, which will run the analytic with different levels of scaling (compute).
The amount of compute capacity available in the Dedicated subscription can be augmented with additional Compute Units. A Compute unit provides additional compute capacity to accommodate more use cases, where each use case can consist of multiple feeds, real-time analytics, and big data analytics. When compute reaches 75 percent capacity, an alert will be sent to the organization administrator so they can determine if add-on Compute Units need to be purchased.
Administrators can view the percentage of compute used on the Home page in the Velocity application. Additionally, the Compute Utilization page reports the percentage of compute used across feeds, real-time analytics, and big data analytics, as well as the percentage of compute used by each individual item. For details, see Compute and storage management.
An ArcGIS Velocity subscription includes a given amount of feature storage for observation data and analytic results. The amount of storage included in the subscription varies by the license level.
- Standard: 128 GB
- Advanced: 1 TB
- Dedicated: 3 TB
The number of features that can be stored depends on the schema of the data (number of attributes) and the complexity of the geometry. For example, up to tens of millions of records of point data can be supported with the Standard subscription, up to hundreds of millions with the Advanced subscription, and over one billion records with the Dedicated subscription.
The amount of feature storage for the Advanced and Dedicated subscriptions can be augmented with additional Storage Units. When feature storage is at 50 percent capacity, an alert will be sent to the organization administrator to determine if add-on Storage Units need to be purchased. Once storage is added, it cannot be removed.
Administrators can view the percentage of storage being used on the Home page in the Velocity application. Additionally, the Storage Utilization page reports the percentage of storage used by different system components as well as the percent storage used by each feature layer. For details, see Compute and storage management.
