The challenge

Where teams get stuck

The problems we're most often brought in to solve.

  1. 01

    Enterprise compliance does not fit

    An enterprise customer's data residency or isolation requirements cannot be met by the current shared-schema model.

  2. 02

    No per-tenant usage metering

    Consumption cannot be measured per tenant, so usage-based pricing and fair resource limits are not possible.

  3. 03

    Noisy neighbours degrade performance

    One heavy tenant slows the platform for everyone because there are no per-tenant limits or workload separation.

Overview

Multi-Tenant Architecture at VulcanTech

Multi-tenant architecture is a SaaS design in which one platform serves many customers while keeping each tenant's data and configuration isolated. VulcanTech architects platforms using shared schemas with row-level security, or isolated schemas and databases per tenant, matched to your compliance and scale requirements. Tenant-aware authentication, permissions, usage metering and rate limiting are designed in, so the platform meets stricter enterprise requirements as they arrive.

Key deliverables

  • Tenant isolation strategy (row-level security vs. schema-per-tenant)
  • Tenant-aware identity and role-based permissions
  • Per-tenant usage metering and rate limiting
  • Automated tenant provisioning
  • Isolation test suite

What you get

What Multi-Tenant Architecture includes

  • Tenant isolation strategy

    Row-level security, schema-per-tenant or database-per-tenant, selected per requirement and documented.

  • Tenant-aware identity

    Authentication, single sign-on and permissions scoped to each tenant and its users.

  • Usage metering

    Per-tenant tracking of API calls, storage and activity to support pricing and capacity planning.

  • Rate limiting

    Per-tenant limits that protect shared resources from heavy or abusive workloads.

  • Automated tenant provisioning

    Onboarding that creates tenant configuration, defaults and initial users consistently.

  • Isolation assurance testing

    Automated tests verifying that no tenant can read or modify another tenant's data.

Our process

How we deliver

A delivery process you can see into — from first workshop to production support.

Book a free consultation
  1. 01

    Discovery

    A focused working session on your objectives, constraints and existing systems. It concludes with a scoped proposal and a clear view of value, risk and effort.

  2. 02

    Architecture & planning

    We agree the target architecture, data model and integration approach before product code is written, and secure your sign-off.

  3. 03

    Iterative delivery

    Working software reaches a staging environment on a regular cadence, giving stakeholders continuous visibility and the ability to steer priorities.

  4. 04

    Assurance & hardening

    Automated testing, accessibility and performance budgets, and a security review are completed before anything reaches production.

  5. 05

    Launch & continuity

    We manage cutover and remain engaged through an agreed support period, with a structured handover to your teams or ongoing operation by ours.

Engagement models

Work with us the way that suits you

  • Outcome-based delivery

    A defined scope, timeline and commercial model agreed after discovery. We own delivery risk against the agreed outcomes.

    Best for: Well-defined initiatives, MVPs and first releases

  • Dedicated product teams

    A cross-functional pod — engineering, design, QA and delivery leadership — aligned to your roadmap and scaled as priorities change.

    Best for: Long-term product development and evolving roadmaps

  • Team extension

    Senior engineers embed in your organisation, work inside your processes and report to your leaders — on contracts that assign all IP to you.

    Best for: Adding specialist capability without growing headcount

Why VulcanTech

A partner, not a vendor

Senior engineering, honest delivery, and work we can name.

  • Senior engineers own delivery

    The engineers who scope your programme in discovery are the engineers who deliver it. There is no hand-off to a junior bench after contract signature.

  • Engagement models that fit

    Outcome-based delivery, dedicated product teams, team extension or global capability centres, matched to how your organisation prefers to work.

  • A verifiable track record

    Every customer story we publish describes real production work, naming the client wherever confidentiality allows, including public-sector platforms secured through competitive tenders.

  • 80+ projects in 16 countries

    Delivered since 2021 across the public sector, real estate, healthcare, manufacturing and consumer technology, for regulated and high-growth organisations alike.

FAQ

Frequently asked questions

Can't find what you need? Ask us in the discovery session.

A shared schema with row-level security is less costly to run and simpler to maintain for most SaaS products. We move specific tenants to separate schemas or databases when compliance requirements, such as data residency or contractual isolation, demand it. Many platforms run a hybrid model, and we design for that possibility from the outset.
