The number and locations of Discovery Apps depend on several factors, including:

- The size of the network to scan
- Number of discoverable assets
- Time required to complete all scans
- Number of logically or physically separated networks

Key questions to consider:

- How many data centres or cloud environments will be scanned?
- What connectivity/bandwidth exists between each data centre?
- Do firewall rules/router settings prevent scanning between data centers? (see Authentication Requirements for ports/protocols)
- How many IP subnets per DC/Cloud environment?
- What is the approximate number of devices/virtual servers per subnet?
- What is the desired scan frequency?
