Different motivations lead to different TCO outcomes. Cost savings, agility, scalability, and compliance each drive different decisions.
Already decided — comparing deployment models
Cost reduction is the primary driver
Agility and scalability are primary drivers
Vendor is forcing cloud migration
Cloud may not be cheapest option

💰
What is your current annual on-premise software and infrastructure cost?
Include: licences, hardware depreciation, data centre, power/cooling, networking, and staff allocated to on-premise operations.
Fully calculated including all cost categories
Licences and hardware known, other costs estimated
Only licence costs known
Total on-premise cost not calculated
Question 3 of 7
👥
How many dedicated infrastructure staff support your on-premise environment?

Question 4 of 7
📦
Have you modelled the full cloud cost including all components?

Full model including all cost categories
Subscription costs modelled, other costs estimated
Only vendor cloud pricing reviewed
No cloud cost model built
Question 5 of 7
🔄
How complex is your application landscape for cloud migration?
Highly customised, legacy, or tightly-integrated applications significantly increase migration cost and risk.
Simple — standard applications, minimal customisation
Moderate — some custom applications
Complex — heavily customised, many integrations
Very complex — legacy systems, mainframe dependencies
Question 6 of 7
📊
Have you evaluated consumption-based vs subscription cloud pricing?
Cloud pricing models vary. Consumption-based (pay-as-you-go) vs subscription (committed) have different cost profiles.
Both models evaluated and compared
Primary model selected, alternative considered
Only one model reviewed
Pricing models not evaluated
Question 7 of 7
📅
What is your target migration timeline?
Migration timeline affects cost phasing. During migration, you pay for both on-premise and cloud (dual-running costs).
18+ months — phased approach
12-18 months
6-12 months — aggressive
Immediate or vendor-forced deadline
