Traditional SCADA cost analysis. Maintaining a traditional (owned) SCADA system requires ever more frequent and increasing costs. Utilities must consider:
• Capital investment to replace an aging SCADA system
• Software and third-party upgrades
• Security patches
• First-party and third-party licenses
• Maintenance and vendor support
• Data expansion and regulatory compliance
Over a seven-year period of owning and maintaining a traditional SCADA system the cumulative cost more than triples the initial capital investment…With SCADA as a SERVICE most of the traditional SCADA costs are no longer applicable:
• No capital investment is necessary
• No cost for software and third-party upgrades
• No cost for security patches
• No cost for first-party and third-party licenses
• No maintenance cost and fees for vendor support
• No cost for regulatory compliance
With SCADA as a SERVICE the costs utilities have to pay are dramatically reduced to:
• Monthly subscription
• Data expansion on as-needed basis
A comparison of the costs over a seven-year period shows that SCADA as a SERVICE offers much higher value for a fraction of the cost of the traditional SCADA
