Multi-Tenant SaaS Architecture

The optimal choice depends on your tenant isolation requirements and scale. MicrocosmWorks typically recommends a shared-database, separate-schema approach for most B2B SaaS products because it balances cost efficiency with data isolation, though we implement database-per-tenant for clients in regulated industries like healthcare or finance where strict data segregation is mandated. Our architects evaluate your compliance needs, expected tenant count, and query patterns before recommending the right tenancy model.

MicrocosmWorks implements tenant-aware rate limiting, connection pooling with per-tenant quotas, and resource isolation at the compute layer to prevent noisy-neighbor problems. We use techniques like weighted fair queuing and tenant-specific caching tiers so that a sudden spike from one customer does not cascade into latency for others. For enterprise-tier tenants, we can provision dedicated compute partitions while keeping the shared control plane intact.

MicrocosmWorks offers architecture design and implementation services at consulting rates between $15-$45/hr depending on the complexity and team seniority required. A typical multi-tenant SaaS architecture engagement—covering database design, tenant isolation, authentication, and deployment pipelines—runs 8-16 weeks with a cross-functional team. We scope every project with a fixed-price discovery phase so you have full cost visibility before committing to the build.

MicrocosmWorks builds automated tenant provisioning pipelines that handle schema creation, DNS configuration, feature flag initialization, and seed data deployment within minutes of a new signup. We use infrastructure-as-code tools like Terraform or Pulumi combined with event-driven workflows so that each new tenant gets a fully configured environment without manual intervention. This approach lets our clients scale from 10 tenants to 10,000 without changing the onboarding process.

MicrocosmWorks implements a configuration-driven customization layer using feature flags, tenant-specific metadata, and a plugin architecture that allows per-tenant behavior without code branching. We design extensibility points at the UI theming, workflow engine, and integration layers so tenants can have unique branding, business rules, and third-party connections all managed through configuration. This keeps your engineering team maintaining a single codebase while supporting diverse customer requirements.
