TL;DR

• On-premises AI offers significant CapEx savings vs private cloud
• On-premises AI ROI is faster than cloud
• On-premises AI offers better data control and risk mitigation than private cloud

While hosting generative AI (generative AI) in the public cloud is a common starting point, many enterprises eventually run into a wall of compliance issues, security vulnerabilities, and unpredictable cloud bills.

A comprehensive total cost of ownership (TCO) report by Principled Technologies reveals that pulling generative AI workloads out of the cloud and onto an onsite infrastructure like the Dell AI Factory completely flips the economic script. Whether you purchase your hardware upfront (CapEx) or utilize flexible consumption with Dell APEX Infrastructure, going onsite gives you ultimate control while heavily padding your bottom line.

Here are five major reasons why an onsite AI factory wins over public cloud alternatives.

1. Massive savings on upfront investments (CapEx)

If your organization prefers a traditional capital expenditure (CapEx) model by purchasing infrastructure upfront, the long-term savings compared to public cloud hyperscalers are staggering. According to the four-year TCO projections, an on-premises Dell AI Factory solution allows you to:

• Save up to 63% compared to a competitive AWS SageMaker environment.
• Save up to 61% compared to a competitive Azure Machine Learning environment.

2. Rapid ROI (1.5-year break-even)

When deploying a massive enterprise technology like generative AI, proving a quick time-to-value is critical for leadership backing. Transitioning to a Dell AI Factory on-premises solution doesn’t leave your capital tied up indefinitely. The Principled Technologies data highlights that the on-premises CapEx model reaches a definitive break-even point at just 1.5 years compared to both AWS and Azure alternatives, accelerating your timeline to pure profitability.

3. Pay less from day one with Dell APEX

Don’t want to tie up capital in upfront hardware…
