💡

Immediate cost optimizations

Concrete savings actionable without architectural rebuild

Reserved Instances 1-year

240 €/mo

1-year commitment on 24/7 VMs (stable production) = ~25% discount. ROI from month 4.

Cloudflare Free CDN

50 €/mo

Cloudflare Free covers most marketing site cases. Migration in < 1h.

Renegotiate managed ops

43 €/mo

Once 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

#1 Best fitCloud / scale-up consulting firm

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
#2FinOps / Cost Optimization specialist

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 €
#3Cloud Provider Pro Services (AWS, GCP, Azure)

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

Generic profiles for guidance. Get 2-3 concrete proposals before signing — quality gaps inside each category are huge.

Recommended scaling strategyHybrid

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.

1App servers (frontends + backend) on horizontal scaling with autoscaler
2Database on vertical scaling until reaching the largest available instance
3Once DB limit reached: read replicas to scale reads
4Beyond: sharding by tenant (SaaS) or by business entity (marketplace per seller)
5Mandatory cache to absorb DB pressure (Redis with tag-based invalidation strategy)
6Document clearly when to switch each layer to the next level

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
