Enterprise app development requires security, scalability, and compliance. Learn architecture patterns, infrastructure decisions, and best practices.
Enterprise App Requirements
Security: SOC 2 Type II compliance, GDPR compliance, HIPAA compliance (if applicable), encryption at rest and in transit, regular security audits, penetration testing.
Scalability: Multi-region deployment, auto-scaling infrastructure, database replication, CDN, caching layers, load balancing.
Compliance: Industry-specific regulations, data residency requirements, audit trails, access controls, data retention policies.
Architecture Patterns
Microservices: Independent services that scale separately, better fault isolation, technology diversity, but increased complexity.
Monolith with Modules: Simpler to develop and deploy, easier debugging, but harder to scale individual components.
Serverless: Auto-scaling, pay-per-use, no infrastructure management, but vendor lock-in and cold starts.
Infrastructure Decisions
Cloud Provider: AWS (comprehensive services), GCP (strong data analytics), Azure (enterprise integration). Choose based on team expertise and requirements.
Database: PostgreSQL (recommended for most), MongoDB (document store), Redis (caching). Plan for replication and backups.
CDN: CloudFlare, AWS CloudFront, or GCP Cloud CDN for global content delivery.
Security Best Practices
Authentication: OAuth 2.0, JWT tokens, multi-factor authentication, single sign-on (SSO).
Authorization: Role-based access control (RBAC), attribute-based access control (ABAC), principle of least privilege.
Data Protection: Encryption at rest (AES-256), encryption in transit (TLS 1.3), data masking, secure backups.
Compliance Requirements
SOC 2: Security, availability, processing integrity, confidentiality, privacy. Annual audits required.
GDPR: Data protection for EU users, right to access/deletion, data portability, privacy by design.
HIPAA: Healthcare data protection, encryption requirements, access controls, audit logs.
Enterprise Development Tiers
Scale Tier ($125K+): Complex multi-tenant platform, custom infrastructure, advanced integrations, compliance requirements, high-availability architecture, 6-month support.
Timeline: 120 days for enterprise applications with full compliance and security.
