Resource Management on EnOS¶
Default resources are allocated when an organization is created, for performing basic operations such as connecting devices into EnOS. If you need to expand or adjust the capabilities of your clusters on EnOS, you’ll need additional resources or adjust your existing resource quota. EnOS offering online resource management for specific types of resources.
Which Resource can I Manage Online?¶
Currently, you can manage the following computing and storage resources online based on your business needs:
Computing resource for stream data processing. Before running stream data processing jobs, you need to request the Stream Analytics computing resource. Otherwise, the stream data processing jobs cannot be started.
Storage resource for time series data. Before configuring TSDB storage policy for measuring point data, you need to request the TSDB resource.
Computing resource for data analytics. To run data integration and off-line data analytics jobs, you need to request Batch Computing resource.
Storage resources for data to be stored in EnOS Hive. To run off-line data analytics jobs and save data in EnOS Hive, you need to request Data Warehouse resource.
File Storage HDFS
Storage resources for files to be stored in HDFS. To run data analytics jobs and save files in HDFS, or run data archiving jobs to store files in HDFS, you need to request File Storage HDFS resource.
Different resource specifications correspond to different data processing and storage capabilities. For detailed information about the capability of resource units, see Resource Specification.
When Do I Need to Manage My Resources?¶
Requesting New Resources¶
The default deployment of organizations on EnOS supports basic capabilities for device management only. If your business requires data storage in TSDB and stream data processing, you need to request related resources.
Adjusting Existing Resource Quota¶
With business growth, allocated resources may not meet new requirements. You can request resources with higher specification.
With business stabilizing, allocated resources may exceed the business requirements. You can scale down the resource specification to save costs.
Setting Alarms for Resource Consumption Threshold¶
To avoid the impact of insufficient resources on the normal operation of business, you can set alarms against the resource usage rate by monitoring resource utilization in real time. Once the resource usage rate exceeds the specified threshold, the system sends an alert immediately so that the receivers can process the situation in time to ensure stable operation of the business.
Capacity and Limitations¶
- Currently, each organization can request 1 resource instance for stream analytics, TSDB, data warehouse, and file storage HDFS.
- An organization can request 3 resource instances for batch computing, with globally unique queue names.
For the capacity of standard resource instances, see Resource Specification.
