Evaluation Framework

Enterprise Software Decision Rubric

How leading CTOs and product teams evaluate custom software architecture against generic SaaS platforms.

01

Build vs. Buy Economics

When recurring per-user SaaS license fees exceed custom development TCO within 24 to 36 months, building custom ERP provides permanent intellectual property ownership and zero ongoing licensing tax.

02

Relational ACID Sizing

Financial ledgers, student fee billing, and course registrations demand strict ACID compliance with normalized 3NF PostgreSQL/MySQL schemas, Redis session caching, and read-replica offloading.

03

Private VPC Sovereignty

Enterprise and government clients require complete data residency and isolation. Deploying on private AWS VPC subnets with AES-256 encrypted storage ensures regulatory compliance and security hardening.

04

Strangler Fig Migration

Avoid high-risk big-bang legacy replacements. Modernize systems incrementally by replacing modules in prioritized phases with automated dual-write validation and instant rollback safety.
