Modern laboratories are no longer isolated data silos. They are distributed, high-throughput, compliance-driven systems that must scale, integrate, and remain available without compromise. Prolab LIS Cloud was designed precisely for this reality.
Developed by BlackFlow, the Enterprise Software Development division of Yoctobe Ltd, Prolab LIS Cloud is not just a Laboratory Information System. It is a cloud-native, multi-tenant enterprise platform engineered for both high-volume diagnostic labs and agile smaller laboratories operating under strict regulatory and operational constraints.
This project reflects how BlackFlow approaches enterprise software development services: building systems that remain stable under pressure, adaptable under growth, and secure by design.
Built for Throughput, Not Just Features
Most LIS platforms fail when scale becomes real. Prolab LIS Cloud was architected from day one to handle thousands of concurrent samples, users, and integrations without degradation.
At its core lies a microservices architecture where each business capability operates independently. Sample lifecycle management, patient records, results validation, reporting, billing, and integrations are isolated services communicating through well-defined APIs. This prevents cascading failures and allows the platform to evolve without risky monolithic releases.
The backend is built using .NET Core, chosen for its performance, strong typing, and suitability for complex business domains. Node.js complements this with lightweight asynchronous services and API gateways, enabling efficient orchestration and external integrations.
Data consistency and performance are ensured through PostgreSQL for transactional integrity and Redis for high-speed caching, queues, and session handling. This combination allows Prolab LIS Cloud to maintain responsiveness even during peak operational hours.
Cloud-Native Scalability and High Availability by Design
Prolab LIS Cloud runs on Kubernetes, not as an afterthought but as a foundational design choice. This enables:
Automatic horizontal scaling when workload increases
Self-healing services that recover from failures without manual intervention
Rolling updates with zero downtime
Clear separation between environments and tenants
This architecture supports both a single laboratory and a nationwide lab network using the same platform, with no architectural compromises. It also gives operators confidence that growth will not introduce instability.
For organisations evaluating long-term technology partners, this is where BlackFlow differentiates itself. Scalability is not promised; it is engineered.
Security That Matches Clinical and Enterprise Expectations
Laboratory systems sit at the intersection of sensitive health data and operational infrastructure. Prolab LIS Cloud treats security as a first-class concern.
Authentication supports Multi-Factor Authentication and OAuth-based social login, allowing seamless yet secure access for staff, clinicians, and external stakeholders.
Access control is enforced through fine-grained Role-Based Access Control (RBAC). Permissions are defined at a granular level, ensuring that users only see and act on what they are authorised to handle. A lab technician, a quality manager, and an auditor experience the system differently, by design.
All data is encrypted in transit and at rest. Comprehensive audit trails support compliance, traceability, and accountability — essential in regulated environments.
This level of security is not generic SaaS security. It is enterprise-grade, domain-aware, and operationally practical.
Multitenancy Without Trade-Offs
Prolab LIS Cloud supports true multitenancy, allowing multiple laboratories, organisations, or clients to operate on a shared platform while remaining fully isolated.
Each tenant benefits from:
Independent data boundaries
Configurable workflows and test panels
Centralised monitoring and analytics when required
This makes the platform suitable for private lab groups, public health networks, research organisations, and service providers offering LIS as a managed solution.
Designing multitenancy correctly is difficult. BlackFlow’s experience in enterprise software development services ensures it is done without sacrificing performance, security, or maintainability.
Why Prolab LIS Cloud Matters Beyond Laboratories
Prolab LIS Cloud is important not only as a product, but as a reference implementation of how BlackFlow builds complex enterprise systems.
It demonstrates:
How microservices can be applied pragmatically in regulated domains
How cloud infrastructure can deliver resilience without operational chaos
How security and usability can coexist
How platforms can be built to scale for years, not quarters
For organisations considering a strategic technology partner, this project answers a critical question: can this team deliver systems that survive real-world pressure?
Partnering With BlackFlow
BlackFlow does not sell templates. It builds tailored, production-grade platforms for organisations that cannot afford failure.
If you are planning:
A large-scale SaaS platform
A regulated enterprise system
A migration from legacy monoliths to cloud-native architecture
A product that must scale without rewriting core systems
Then exploring BlackFlow’s enterprise software development services is a logical next step.
Behind Prolab LIS Cloud is a team that understands architecture, delivery, and long-term ownership. That is the difference between shipping software and building platforms that last.
