Section 1: Understanding BTP Credit Consumption
SAP BTP credits are not created equal. Each service consumes credits at a different rate depending on runtime, storage, and compute intensity. This fundamental asymmetry is why enterprises with similar BTP footprints can have wildly different cloud costs.
The credit multiplier effect is stark. SAP HANA Cloud burns credits at approximately 10 times the rate of Integration Suite for the same runtime period. A single unscheduled HANA Cloud instance running 24/7 for a month can consume more credits than an entire Integration Suite estate with dozens of iFlows.
The architecture of BTP compounds visibility problems. Most enterprises organise their BTP landscape into multiple subaccounts—one per business unit, team, or project. While this isolation provides governance benefits, it creates blind spots: the Global Account dashboard shows total credit balance, but not which subaccount is burning credits fastest. Most enterprises have no way to answer "Which team is consuming the most credits?" without manual interrogation of each subaccount.
This lack of visibility drives waste. Because nobody sees the cost signal at the team level, overspending happens undetected until the quarterly review. By then, credits are already spent.
Market data suggests that 80% of organisations exceed their cloud budget in the first 18 months of BTP deployment. This is not because BTP is inherently unaffordable—it's because enterprises fail to implement early consumption governance.
Why Credits Burn Faster Than Expected
Development and test instances are the primary culprit. A HANA Cloud instance provisioned for dev work in Monday-morning standup is rarely deprovided after Friday. Instead, it runs idle through the weekend and holidays, burning credits to maintain a connection pool and memory footprint. Over a year, an 8-hour weekday instance costs nearly as much as a 24/7 instance because enterprises fail to schedule shutdown.
Similarly, Integration Suite iFlows remain active after their parent projects are decommissioned. An integration between a legacy EDI system and a vendor portal may be rebuilt three times over five years as systems migrate. But the original iFlow rarely gets deleted—it just sits dormant, consuming credits on every trigger event, even if those triggers fire only once per week.
Section 2: The BTP Cockpit — Your Starting Point (But Not Enough)
The SAP BTP Cockpit is where most organisations begin their cost journey. It provides essential visibility: total credit balance, service subscription status, and subaccount hierarchy. But it is not sufficient for cost optimisation.
What the BTP Cockpit Shows Well
The Cockpit excels at high-level accounting. You can see:
- Total credits remaining in the Global Account
- Which services are subscribed in each subaccount
- The hierarchy of your subaccount and directory structure
For a CIO running a monthly board-level budget review, this information is sufficient to answer "Are we on track?" But it does not answer the questions that actually drive optimisation.
The Cockpit's Blind Spots
The Cockpit does not show:
- Credit burn rate by service: You cannot see whether HANA Cloud or Integration Suite is consuming more
- Forecasted depletion date: The Cockpit shows balance but not trajectory
- Cost per subaccount or team: You cannot identify which business unit is the biggest spender
- Service consumption trends: Is burn rate accelerating or stable?
Practical Workaround: Export and Analyse
The solution is to export monthly usage data via the BTP Usage Analytics API and load it into a simple BI tool—or even a well-structured Excel workbook. The API exposes detailed consumption metrics: credits per service, per subaccount, per month. By loading six months of data into a pivot table, you can quickly identify outliers and trends.
Set up a monthly process: extract usage data on the first of each month, build a simple dashboard showing credits by service and subaccount, and share it with your cost owner network. This 30-minute exercise typically uncovers 2–3 quick-win optimisations in the first month alone.
Budget Alerts: The First Line of Defence
Implement budget alerts using the BTP Alert Notification service. Set thresholds at 70%, 80%, and 90% of your allocated credit budget. When the 70% threshold is crossed, send an alert to your CFO and Chief Architect. At 80%, escalate. At 90%, lock new service provisioning.
This simple circuit-breaker pattern prevents surprise overages and forces a conversation about consumption trajectory before it becomes a problem.
Section 3: HANA Cloud Consumption Optimisation (The Biggest Win)
If you optimise nothing else, optimise HANA Cloud. It is the single largest consumer of BTP credits in nearly every enterprise estate. The opportunity for quick wins is enormous.
The Problem: Always-On Development Instances
Most enterprises run their dev and test HANA Cloud instances 24/7. There is no business reason for this. Dev teams work 8am–6pm, Monday to Friday. A 24/7 HANA Cloud instance running 52 weeks a year is burning credits for 40 hours per week of actual use and 128 hours per week of idle time.
The math is brutal: a dev instance that costs 20 credits per week to run during working hours costs 160 credits per week if left running constantly. Over a year, that idle instance costs 240% more than if it were scheduled to start Monday 7am and stop Friday 6pm.
The Solution: Automated Start/Stop Scheduling
SAP HANA Cloud tooling supports automated start/stop scheduling. You can configure an instance to suspend (not delete) every Friday evening and resume every Monday morning. Suspended instances retain all data and configuration but consume zero credits.
The impact is immediate. Scheduling dev/test HANA Cloud instances to run only during working hours typically reduces credit consumption by 50–70%. For an enterprise with ten dev instances, this single change saves tens of thousands of credits per year.
Implement this across all non-production HANA Cloud instances. Ask your architects: "Is any dev or test HANA Cloud instance required to run at 2am on a Sunday?" The answer is always no.
Right-Sizing: The Second Quick Win
Many HANA Cloud instances are over-provisioned. Teams often size instances defensively, requesting 64GB of memory "just in case" when analysis shows they actually use 16GB. Over-provisioning is free at provisioning time but expensive in credits.
Conduct a quarterly right-sizing review using HANA Cloud Memory Usage Statistics. Export the memory consumption metrics for each instance over the past 90 days. If an instance provisioned with 64GB has never exceeded 20GB utilisation, right-size it down.
This review typically surfaces 3–5 instances per enterprise that can be scaled down, saving 15–20% of HANA Cloud spending with zero impact on application performance.
Multi-Tenant Consolidation
Some enterprises run multiple small HANA Cloud instances: one per development team, one per vendor integration project, one per analytics use case. This horizontal scaling creates management overhead and credit inefficiency.
HANA Cloud multi-tenant architecture allows multiple applications to share a single HANA Cloud instance, each with isolated schemas and security contexts. Consolidating five 32GB instances into two 80GB instances reduces credit burn while improving resource utilisation.
Production vs Non-Prod Separation
Use subaccount credit limits to enforce separation. Allocate 70% of your BTP credits to production subaccounts and 30% to dev/test. Set hard limits: when a non-prod subaccount exhausts its allocation, new provisioning is blocked. This prevents a runaway dev environment from starving production.
Section 4: Integration Suite iFlow Governance
Integration Suite is BTP's integration engine. Enterprises deploy dozens or hundreds of iFlows—integration workflows—that move data between systems. Each iFlow consumes credits on execution. Dormant iFlows consume silent credits because they remain active even when unused.
The Hidden Cost of Decommissioned Projects
When a business process is retired—a legacy EDI integration sunsetted, a vendor relationship ended, a merger integration consolidated—the corresponding iFlow is often left running. Why? Decommissioning requires coordination: the business unit must confirm the process is dead, integration must coordinate the shutdown, and architecture must verify no dependent systems are still calling the iFlow.
In the absence of a decommissioning checklist, iFlows sit dormant, consuming credits on every trigger event. Over a year, a dormant iFlow firing once per week—often as error events from upstream systems—silently consumes hundreds of credits.
The Audit: Identify Dormant Flows
Conduct a quarterly iFlow audit:
- Export the full list of iFlows from Integration Suite (available in the Flows UI)
- For each iFlow, query the Operations Monitor to retrieve the last execution date
- Flag any iFlow with zero executions in the last 90 days
- Cross-reference with your business process inventory to confirm decommissioning
- Suspend or delete confirmed-dormant iFlows
A typical enterprise with 100 iFlows will surface 10–15 dormant flows per quarter. Deleting these saves 5–10% of Integration Suite credit spend immediately.
Batch vs Real-Time Decisions
Many iFlows are configured for real-time synchronisation when batch processing would be sufficient. A daily master-data sync from SAP ECC to a downstream system, for example, might be configured to trigger every 5 minutes when a simple scheduled job running once per day would satisfy the business requirement.
Audit your high-execution-count iFlows. Identify candidates where batching 24 executions into one scheduled job would be acceptable. Implementing this architectural change on even 5–10 iFlows typically reduces Integration Suite execution counts by 50–90%, directly translating to credit savings.
Section 5: SAC, Event Mesh, and API Management
Beyond HANA Cloud and Integration Suite, your BTP estate likely includes SAP Analytics Cloud, Event Mesh, and API Management. Each service has unique consumption patterns and optimisation opportunities.
SAP Analytics Cloud: The Story Graveyard
SAP Analytics Cloud users create stories (interactive reports) and often abandon them. Suspended stories—those no longer accessed—still occupy storage and occupy seats. A quarterly story audit typically finds 20–30% of stories abandoned.
Conduct a story audit quarterly: identify stories with zero access in the last 90 days, review with their owners, and archive or delete confirmed-dead stories. Unused data models should also be archived. This overhead reduction frees up capacity for active analytics use cases.
Event Mesh: Queue Depth Management
Event Mesh is a publish-subscribe platform for asynchronous messaging. If message consumers go offline for extended periods, queues accumulate messages. A queue with millions of messages waiting for a consumer to reconnect consumes storage credits continuously.
Monitor queue depth monthly. Set time-to-live (TTL) policies on messages so that old events are purged automatically. When integrations are decommissioned, delete their queues explicitly rather than leaving them orphaned. This housekeeping typically frees up 10–15% of Event Mesh storage.
API Management: Rightsizing API Call Allocations
API Management packages are priced by call volume. Enterprises often purchase API packages based on projected traffic that never materialises. A team sizes an API package for 1 million calls per month but actually makes 50,000 calls.
Review API call consumption monthly. At renewal time, renegotiate or downgrade API call allocations based on actual traffic patterns. This is not a technical optimisation but a procurement one—many enterprises save 30–50% on API Management costs simply by challenging inflated estimates at renewal.
Section 6: Building a Consumption Governance Model
Technical optimisations—scheduling, right-sizing, auditing—deliver 20–30% savings in the short term. But sustained cost reduction requires governance. A consumption governance model embeds cost awareness into your team's daily culture.
Assign Named Cost Owners
For each BTP subaccount, assign a named cost owner. This should not be a dedicated role—it is 10% of someone's time. But critically, the cost owner should span both IT and Finance. Have Finance assign a business unit CFO to partner with your IT cost owner. This dual-ownership model ensures that cost reduction is a shared business objective, not a technical issue.
Monthly Cost Review Cadence
Run a 30-minute monthly cost review meeting with your top 5 subaccount owners. Share the usage report from Section 2. Ask each owner: "Your subaccount burned 15% more credits this month than last month—why?" This simple accountability mechanism drives awareness and corrective action.
Implement Chargeback
Allocate BTP costs to business units based on their subaccount consumption. This chargeback model is the single most powerful behaviour-change mechanism. When a business unit sees a $50,000 cloud bill on their P&L, they become intensely interested in why a dev instance is running 24/7.
Chargeback-based cost control reduces spend by 20–30% without requiring any technical intervention. Teams simply self-police because they see the cost impact directly.
Developer Training
Run a quarterly 30-minute training for developers on BTP cost awareness: how credits work, which services are most expensive, what happens when you provision an instance that runs for a year unused. This training reduces accidental waste by 20–30% simply by raising awareness.
Sandbox Budget Model
Give developers a fixed sandbox credit allocation—for example, 500 credits per developer per quarter. Once exhausted, new sandbox provisioning is blocked unless explicitly approved. This constraint encourages developers to deprovision old instances to make room for new experiments.
