Why the cloud vs on premise decision drives the run cost
The cloud vs on premise decision on S/4HANA drives the run cost across the contract term because the two models commit on different bases, consume on different metrics, and renew on different patterns. The cloud model commits on the subscription with the periodic renewal. The on premise model commits on the perpetual license with the annual maintenance. The customer that selects the model that fits the workload pattern lands the run rate target. The customer that selects the model on the platform preference alone without the run rate model often misses the target. Reference the S4HANA licensing pillar, the license audit complete guide, and the S4HANA expertise.
Entitlement and consumption metric on each model
The entitlement and consumption metric on each model define the run cost driver. The cloud model uses the Full Use Equivalent (FUE) entitlement on the subscription term. The consumption metric tracks the FUE consumption against the committed pool. The on premise model uses the named user entitlement on the perpetual licence. The consumption metric tracks the named user count against the entitlement schedule. The digital access metric applies on both models on the same basis. The engine entitlement on both models tracks the SAP engine consumption. The customer that maps the workload profile against the entitlement metric on each model identifies the cost driver that the negotiation needs to address. Reference the named user types, the licensing models pillar, and the engine licenses analysis.
Contract term, commitment, and the cost glide path
The contract term, the commitment, and the cost glide path differ between the two models. The cloud subscription term runs typically three years with the renewal cycle that resets the entitlement. The on premise contract holds the perpetual licence with the annual maintenance that runs through the contract term. The cost glide path on the cloud model loads the upfront commitment and the subscription run rate. The cost glide path on the on premise model loads the perpetual licence in the first year and the maintenance through the term. The customer that models the cost glide path on both models against the workload growth selects the model that matches the growth trajectory. Reference the multi year contract analysis, the enterprise agreement analysis, and the contract review analysis.
Customer programs that select the S4HANA model on a documented decision framework with the workload mapping and the cost glide path modelled in parallel land the run rate target within approximately 87 percent of the modelled outcome.
Upgrade cadence, release window, and the operational fit
The upgrade cadence and the release window define the operational fit. The cloud model runs the upgrade cadence on the SAP managed schedule with the release window that the SAP roadmap defines. The customer accepts the SAP upgrade timing. The on premise model runs the upgrade cadence on the customer schedule with the release window that the customer programme defines. The customer holds the upgrade timing. The customer that has the operational profile that supports the SAP managed cadence fits the cloud model. The customer that has the operational profile that requires the controlled upgrade schedule fits the on premise model. Reference the security on S4HANA, the change management, and the license optimization expertise.
Exit cost, contract reversal, and the lock in profile
The exit cost, the contract reversal, and the lock in profile define the model risk. The cloud model carries the higher lock in profile because the contract reversal requires the workload migration and the contract termination. The on premise model carries the lower lock in profile because the perpetual licence supports the contract continuation without the renewal. The exit cost on the cloud model includes the data return cost and the migration cost. The exit cost on the on premise model is the maintenance termination only. The customer that values the optionality on the exit favours the on premise model. The customer that values the operational simplicity on the platform favours the cloud model. Reference the compliance framework pillar (cross cluster), the security audit pillar (cross cluster), and the renewal negotiation expertise.
Practical posture for the program
- Cloud and on premise S/4HANA models commit on different bases and consume on different metrics
- Entitlement metric on cloud is the FUE pool, on premise is the named user count
- Cost glide path on cloud loads upfront subscription, on premise loads perpetual licence then maintenance
- Upgrade cadence on cloud follows SAP managed schedule, on premise follows customer schedule
- Exit cost on cloud includes data return and migration, on premise is maintenance termination
- Lock in profile is higher on cloud, lower on on premise with the perpetual licence
