Build vs. Buy Decision Framework

A structured approach to evaluating technology decisions:

Key Decision Criteria

1. Strategic Differentiation: How central is this component to competitive advantage?
2. Time-to-Market: How critical is implementation speed?
3. Resource Requirements: What development, maintenance, and operational demands exist?
4. Flexibility Needs: How much customization and adaptation is necessary?
5. Integration Complexity: How does this component connect with other systems?
6. Market Maturity: Are quality third-party solutions readily available?
7. Total Cost of Ownership: What are the full lifecycle costs of each approach?

Decision Matrix Application

Strategic Consideration: The build vs. buy decision isn't binary but exists on a spectrum including options such as buying and customizing, using open-source foundations, or creating composable solutions from multiple components.

2. Core Infrastructure Decisions

The foundation of a scalable property portal begins with infrastructure choices that balance performance, cost, and operational requirements.

Cloud vs. On-Premises Infrastructure

Evaluating the fundamental platform approach:

Cloud Infrastructure Advantages

• Elastic Scalability: Adapting to traffic fluctuations
• Geographic Distribution: Global performance optimization
• Operational Efficiency: Reduced infrastructure management
• Cost Alignment: Expenses mapped to actual usage
• Rapid Provisioning: Faster environment creation and modification

Case Study: A mid-sized property portal migrated from on-premises infrastructure to cloud services, reducing page load times by 42%, cutting infrastructure costs by 37%, and eliminating capacity planning challenges during marketing campaigns that previously caused performance issues.

Critical Cloud Architecture Decisions

• Cloud Provider Selection: Single vs. multi-cloud strategies
• Service Model Choices: IaaS, PaaS, or hybrid approaches
• Region Distribution Strategy: Geographic deployment approach
• Resource Management: Right-sizing and optimization
• Cost Control Mechanisms: Monitoring and efficiency tools

Implementation Strategy: Many successful property portals adopt a "cloud-first, but not cloud-only" approach, maintaining core operations in the cloud while selectively using specialized services or on-premises solutions for specific needs.

Monolithic vs. Microservices Architecture

Architectural approach significantly impacts development agility and scalability:

Microservices Advantages for Property Portals

• Independent Scaling: Optimizing resources for different functions
• Development Velocity: Parallel work on separate components
