Study Notes

Server Specification for a Backend Development Project

  • CPU: 4 to 8 cores (e.g., Intel Xeon or AMD Ryzen) are recommended.

    • Rationale: Multi-core processors efficiently handle multiple concurrent requests, crucial for interactive websites and complex queries, particularly during peak usage.

  • RAM: 16 GB to 32 GB of RAM is recommended.

    • Rationale: Sufficient RAM is essential for handling multiple user sessions, caching data, and background processes, improving response times.

  • Storage: A Solid State Drive (SSD) of at least 500 GB is recommended.

    • Rationale: SSDs provide faster read/write speeds than traditional hard drives, improving data access and reducing load times. This is significant for applications needing frequent database access.

  • Bandwidth: 1 Gbps or higher bandwidth is recommended.

    • Rationale: High bandwidth ensures quick data transmission between the server and users. This is important for applications with large or complex content.

  • Operating System: Linux (e.g., Ubuntu, CentOS) is recommended.

    • Rationale: Linux provides stability, security, and lower resource requirements, making it a suitable choice for web servers.

  • Database: MySQL or PostgreSQL are recommended.

    • Rationale: Both are robust relational databases capable of handling complex queries and large datasets. The specific choice depends on application requirements.
