Enterprise Architecture

Strategic framework that aligns organization’s business processes, information systems, and technology infrastructure with overall goals & objectives

Features

• Performance: highly available, fast loading & response time that could support critical business operations 24 hours worldwide
• Scalability: able to handle increased workloads as business grows
• Flexibility: adapt to business requirement change such as new processes & regulations
• Security: measures to protect sensitive data & ensure normal operation
• Maintainability: easy to enhance or fix for issue or problem found
• Interoperability: seamless integration with other systems or applications
• Reporting: regular & ad hoc reporting of business situation for management
• Monitoring: auto detect of abnormal and suspicious operation & inform related parties
• Usability: user-friendly interfaces and easy operation
• Cost-effectiveness: value for money of initial and ongoing investment
• Compliance: meets legal and regulatory requirements

Common Implementation

• Redundancy: active-active multi-region deployment to ensure service continuity
• Load Balancing: traffic routing and distribution across geographically dispersed servers
• Auto-Scaling: dynamic resource allocation via server clustering or cloud service
• Fault Tolerance: minimize or isolate errors to prevent service disruption
• Disaster Recovery: failover mechanisms to restore services after system failures
• Data Protection: encryption/ irreversible hashing to store or transit important data
• Access Control: least-privilege permissions with timely revocation
• Security Auditing: detect/resolve vulnerabilities, e.g., code injection, intrusions attempt
• Zoning: network segmentation to isolate critical server assets, e.g., DMZs
• Storage: high-speed, SAN scalable storage with RAID redundancy
• Monitoring: real-time error reporting, performance tracking & anomaly alerts
• Modular Design: reusable components, functions, and API such as microservices
• Optimization: async event-driven communication, database caching, edge computing, and script /code tuning for high concurrency and fast response
• Best Practices: adherence to proven standard, e.g. design pattern, framework
• Comprehensive Testing: cover all scenarios, user groups, workflows, & devices
