Software Engineering FAQ

Frequently Asked Questions: Software Development

Clear answers on architecture patterns, code ownership, multi-tenant isolation, and zero-downtime migration.

What architecture patterns does DecillionX use for scalable enterprise software?
We implement domain-driven design (DDD), decoupled event-driven microservices (using Apache Kafka and RabbitMQ), multi-tier caching (Redis, CDN edge caching), and database sharding with PostgreSQL and distributed NoSQL systems to handle high transactional throughput.
Does DecillionX transfer full source code and intellectual property ownership?
Yes, 100%. Upon completion of milestone deliverables and invoice clearance, all source code, database architectures, CI/CD pipeline scripts, and intellectual property (IP) rights belong exclusively to the client without recurring licensing fees.
How does DecillionX ensure multi-tenant data isolation and security in SaaS platforms?
We engineer rigorous tenant isolation patterns based on client requirements: database-per-tenant, schema-per-tenant, or partitioned row-level security (RLS) with cryptographic key isolation, automated cross-tenant leak detection, and granular RBAC permissions.
How do you handle migration from legacy monoliths to modern microservices without downtime?
We utilize the Strangler Fig migration pattern combined with blue-green deployments, canary releases, and dual-write synchronizers to incrementally decompose monolithic systems into high-speed microservices with 0% operational downtime.
