The Economic and Strategic Benefits of Cloud Computing

Does SaaS save money? Traditional vendors of IT products and services sometimes argue that systems deployed on-premise are more cost-effective over the long run than their cloud-based counterparts. They claim that while licensed software may have higher acquisition costs, they are amortized over a fixed time period in contrast to Software-as-a- Service or SaaS, subscription fees, which continue for the life of the offering in the form of recurring per-user fees.

Cloud providers, on the other hand, argue that the upfront savings are significant and that, in any event, the real benefits of SaaS are not in direct cost savings but in the strategic advantages that the cloud brings to the organization. Which side is correct? The answer is not an academic exercise. For organizations to make intelligent decisions regarding the cloud, it is important to understand the relative costs of SaaS vs. on-premise systems.

Based on a recent survey of organizations that have fully or largely migrated to the cloud, it was found that such organizations save on average more than 20% in IT spending as a percentage of revenue. Savings measured on a per-user basis are 16%. Savings come not only from a reduction in data center spending but also from lower IT personnel costs.

This report outlines the strategic benefits of cloud computing beyond cost savings and concludes with recommendations on developing a strategic road map for full migration to the cloud.
