Monthly cost breakdown
On AWS at list prices (no commit discounts)
Indicative pricing. Expect ±20% based on real usage, commitments, support, and negotiated discounts.
Cloud provider comparison
Same services, same sizes. AWS/GCP = rich features but expensive. OVH/Scaleway = excellent value in Europe.
Immediate cost optimizations
Concrete savings actionable without architectural rebuild
Reserved Instances 1-year
−240 €/mo1-year commitment on 24/7 VMs (stable production) = ~25% discount. ROI from month 4.
Cloudflare Free CDN
−50 €/moCloudflare Free covers most marketing site cases. Migration in < 1h.
Renegotiate managed ops
−43 €/moOnce infra is stable, managed ops can drop from 15% to 10%. Get 2-3 competing quotes.
Cumulative potential savings
−333 € / month
Not all combine (reserved + spot partially exclude each other). Count 60–70% of the sum as a realistic target.

Recommended profiles for your level (Scale-up) — ranked by value-for-money and fit
The structuring partner for the scale-up transition
Rate
€1,500 – €2,500 / day
Mission length
2 to 6 months
When to call : Architecture rebuild, internal platform setup (IDP), monolith → modular or targeted microservices transition, advanced FinOps.
Strengths
- + Senior multi-disciplinary expertise
- + Structured delivery capacity
- + Knowledge transfer along the way
Limits
- − Significant day rate
- − 2-3 week onboarding
- − Risk of report without execution
Pure focus on cloud bill reduction
Rate
€800 – €1,500 / day OR % of savings
Mission length
5-10 day audit then monthly follow-up
When to call : Cloud bill > €3,000/mo and the internal team has no time to optimize. ROI often net within first weeks.
Strengths
- + Measurable and fast ROI
- + % of savings model possible
- + Actionable recommendations
Limits
- − Scope limited to cost
- − No long-term architecture advice
- − Risk of fragility to save €
Native provider expertise for structuring projects
Rate
€2,000 – €3,500 / day (often in credits)
Mission length
Project-based fixed-fee
When to call : Major cloud migration, compliance certification (SOC2/ISO), reference multi-region architecture.
Strengths
- + Native platform expertise
- + Credits often available
- + Access to product roadmaps
Limits
- − Vendor-biased (of course)
- − Very expensive outside credits
- − Variable availability

Recommended scaling strategy — Hybrid
How to grow technically without breaking everything
Hybrid scaling: vertical on the DB (which scales horizontally poorly), horizontal on stateless app servers. The strategy of most mature scale-up platforms.
Expert advice tailored to your profile
4 complementary perspectives on your architecture
DevOps & Cloud Scale Architect
Capacity planning, IaC automation, continuous delivery, multi-provider cloud optimization
- •Strictly document module boundaries (DDD) — one module does not access another's DB
- •CI/CD per module — integration tests limited to touched modules
- •Prepare service extraction by monitoring module usage (operational cost per feature)
- •Feature flags per module to decouple release and deployment
SRE / Platform & Kubernetes Architect
SLO, observability, resilience, error budgets, incident response
- •SLO per business module + global SLO
- •Per-module metrics: how many transactions fail due to module X?
- •Failover test by disabling a non-critical module (feature flag off) — graceful degradation
- •Prepare observable separation of the module worth extracting
Solution Architecture / Tech Strategist
Long-term vision, structuring choices, business × tech alignment, governance
- •Multi-tenancy: isolation by tenant_id from the data model or separate DBs for big tenants? Decide early
- •Granular RBAC (roles, permissions, scopes) — underestimated at start, painful to retrofit
- •Immutable audit trail (event sourcing) for future SOC2/ISO 27001 compliance
- •Billing: Stripe Subscriptions vs Recurly vs custom — each has its flexibility trade-off
- •Public API = long-term commitment: explicit versioning, deprecation policy, contractual SLA
UX/UI Growth & Conversion Director
Tech impact on UX, SEO, conversion, retention
- •Time-to-Value (TTV) < 5 min = 2× higher activation — onboarding product must enforce it
- •Auto sandbox for each new tenant = friction-free trial
- •Fast dashboards (< 1s on aggregations) = daily engagement — else abandonment
- •Product notifications (in-app + email digest) = +20% retention
- •Built-in A/B testing early = data-driven product decisions
