In a perfect world, on-premise storage infrastructure is refreshed every five years. That timeframe isn’t realistic for law enforcement agencies. The benefit of using cloud resources is that it removes the need to buy all new hardware. As a cloud services provider, AWS handles the refresh so that organizations always have the latest storage and pay for only what they need.
Often backup systems in agencies take the form of a NAS device underneath someone’s desk. In the event of a natural disaster, everything would be lost. Even if the backup wasn’t destroyed, there may not be access to it, and the operation would be down. With cloud storage, mission-critical systems can continue to operate simply because the system is in a separate location.
