The sizing of the overall system is determined by the following considerations:
- Number of connected users
- Factories managed
- Number and type of devices
- Data ingest and retention rates
- Real-time and historical analytics operations
- Size of datasets
Also, the system workload profile may change over time and companies must consider future growth, as well as policies and procedures to meet those demands, by scaling the system. All these factors are described in Accelerated Time to Value.
