Large‑scale user bases

Scale to millions with a per‑installation license — no per‑user caps. Run horizontally with zero‑downtime upgrades at customer sites or in your cloud.

Industry Context

Archetype: Platforms with very large, intermittently active user populations

E‑commerce, financial services, and insurance portals where many users log in infrequently, but the total population is huge.

Challenges

Maintain predictable costs and performance at very large user counts without per‑user licensing, while meeting enterprise reliability expectations.

  • Avoid runaway license costs at high user counts
  • Scale horizontally with HA and zero‑downtime updates
  • Meet compliance and residency constraints by running in customer infrastructure

Solution Approach

ProAuth’s flat‑rate, self‑hosted model runs in your infrastructure and scales on Kubernetes without per‑user limits.

Enterprise license with no user or application caps

Kubernetes horizontal scaling and autoscaling

Deploy at customer sites or in your cloud with the same architecture

Architecture & Operations

Customer‑hosted or first‑party cloud Kubernetes with replicated services.

  • ProAuth core services with HA configuration
  • Observability (metrics, logs, traces) and auditing
  • Config‑as‑code and CLI for repeatable operations

Zero‑downtime upgrades and rolling strategies; tenant‑aware partitioning where needed.

Implementation

Timeline: Typically weeks, depending on federation and data migration requirements.

  1. P0: Capacity and HA planning
  2. P1: Kubernetes deployment and automation
  3. P2: Federation/SCIM and tenant partitioning
  4. P3: Cutover and production hardening

Results & Benefits

  • Predictable costs for high‑volume, low‑frequency usage patterns
  • Operational continuity during updates
  • Control over data residency and compliance

Future Expansion

  • Broader federation catalog
  • Expanded autoscaling playbooks

Why ProAuth

  • Enterprise license with no user or application limits
  • Kubernetes horizontal scaling and autoscaling
  • Tenant‑aware user stores and federation patterns that scale

How it fits

  • Deploy containerized and scale replicas for throughput and high availability
  • Partition per tenant with dedicated stores or federate to external IdPs

Outcomes

  • Predictable costs for high‑volume workloads
  • Operational continuity during updates
