The short version

  • Only Java has a free tier, so it costs nothing to try first.
  • Each has a real cost: Java windows support limited to 64-bit operating systems only; SAP S/4HANA implementation and integration costs routinely run to several times the software cost, and the subscription clock typically starts long before go live, so the first contract year buys much less usable production time than the headline suggests.
  • They diverge on capability: Java covers Object-oriented programming, SAP S/4HANA covers HANA in-memory database.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Java

  • Windows support limited to 64-bit operating systems only
  • Linux installation requires manual path configuration for most installation methods
  • macOS support limited to Intel x64 and Apple Silicon (AArch64) architectures

SAP S/4HANA

  • Implementation and integration costs routinely run to several times the software cost, and the subscription clock typically starts long before go live, so the first contract year buys much less usable production time than the headline suggests.
  • Custom ABAP from an ECC installation must be assessed against the simplification list and either retired or rebuilt, and this remediation is normally the largest and most underestimated line in a brownfield conversion.
  • The public cloud edition constrains modification by design, so organisations that depend on non-standard processes are pushed either to change the process or to pay for the private edition, and that decision is often made after the contract is signed.
  • SAP intends extensions to live on the separately licensed Business Technology Platform, so the extensibility model that makes upgrades safe also adds a second subscription and a second set of skills to the total cost.
  • Exit is effectively impossible at reasonable cost, because the data model, the accumulated configuration and the trained staff around a large installation represent a switching cost that outweighs any competing vendor's discount, so the decision binds for a decade or more.

Answered from the vendors’ own pages

SAP S/4HANA: What is the actual deadline for leaving ECC?

SAP has set mainstream maintenance for the older Business Suite to end in 2027, with paid extended maintenance available for a further period to 2030. Confirm the current dates and terms with SAP directly, because the commercial detail has been adjusted more than once and it determines your negotiating window.

SAP S/4HANA: Greenfield or brownfield?

Brownfield carries your existing configuration and custom code forward, which is faster to start and slower to finish because everything must be remediated. Greenfield rebuilds on standard processes, which costs more in change management and leaves a cleaner system. The right answer depends mostly on how much of your existing configuration you would defend to a board.

SAP S/4HANA: Is the public cloud edition cheaper?

To run, generally yes. Whether it is cheaper overall depends on whether your processes fit within its extensibility limits. If they do not, the savings evaporate into workarounds or into a move to the private edition.

SAP S/4HANA: How should I approach pricing negotiation?

Treat licence, infrastructure, BTP, the integrator and the internal backfill as one number and negotiate against it. Also settle indirect and digital access terms explicitly in writing, since usage from connected systems has been a recurring source of unbudgeted cost.
