1. Acquisition of Assets
This foundational phase in database implementation focuses on assembling the necessary components—hardware, software, and personnel—that form the backbone of a robust and scalable database system. These assets ensure high availability, security, and performance throughout the database lifecycle.
a. Hardware Assets
Efficient and scalable database systems depend heavily on the underlying hardware infrastructure. Key hardware components include:
• Servers (Physical or Virtual)
- The server must offer multi-core processors (e.g., Intel Xeon or AMD EPYC), large RAM capacity (32 GB to several TB), and redundancy (RAID, dual power supplies).
- Physical servers are preferred for latency-sensitive, I/O-heavy applications like high-frequency trading.
- Virtual servers (VMware, Hyper-V, or KVM-based) offer flexibility and are cost-effective for cloud-native or microservice-based systems.
Example: A financial institution deploying Microsoft SQL Server for real-time risk analytics might use Dell PowerEdge R750 servers, each equipped with:
