Sizing and scalability factors per environment
This section explains the sizing and scalability factors that you must consider before you begin deploying the BMC Cloud Lifecycle Management solution. The following topics are covered in this section:
Before you begin
Before you complete the sizing for your cloud deployment, ensure that you have your business requirements and use case ready.
Sizing factors
The three factors that determine the sizing of BMC Cloud Lifecycle Management products are: Number of concurrent users, provisioning rate, and size of managed environment. These factors directly or indirectly affect the sizing of products in the BMC Cloud Lifecycle Management stack. The following table illustrates the effect of the sizing factors on each product in the solution.
Product | Primary factors affecting sizing |
|---|---|
Enterprise AR (Including Midtier) | Number of Concurrent Users |
Cloud DB(CAR) |
|
CLM |
|
BBSA |
|
BBNA | Size of Managed Environment |
BPPM | Size of Managed Environment |
BAO |

Impact of changes in sizing factors
Any changes in the sizing factors have varied impact on the products in the BMC Cloud Lifecycle Management stack. The following table illustrates the effect of the changes in provisional rate or managed environment on the cloud components.
Factors | Enterprise AR System | Cloud Database | Cloud Core components | BMC Server Automation | BMC Network Automation | Database |
|---|---|---|---|---|---|---|
Increase in Users/Provisional Rate | Medium Impact | High Impact | High Impact | Medium Impact | Low Impact | Low Impact |
Increase in Managed Envrionment | Low Impact | High Impact | Low Impact | High Impact | Medium Impact | Medium Impact |
- High – The impact of change on the CPU usage is considerable, probably as high as 2x.
- Medium – The impact of change on the CPU usage is marginal, say 1.5x
- Low – The impact of change on the CPU usage will not have much effect on CPU.
