2. Data Center Architecture

2.1 Modular Data Center Architecture

Modular Data Center Architecture involves the construction of data centers in a modular fashion, where individual modules can be added or removed as needed. This approach allows for scalability and flexibility, enabling organizations to expand their data center capacity incrementally. Each module typically includes its own power, cooling, and IT infrastructure, making it a self-contained unit.

For example, a large e-commerce company might start with a basic modular data center and add more modules during peak shopping seasons to handle increased traffic. This flexibility ensures that the company can scale its infrastructure without a significant upfront investment.

2.2 Mainframe Data Center Architecture

Mainframe Data Center Architecture relies on centralized mainframe computers to handle large-scale processing and storage needs. This architecture is characterized by its high reliability, security, and processing power, making it suitable for mission-critical applications. Mainframes are often used in industries like finance, healthcare, and government, where data integrity and processing speed are paramount.

An analogy for this architecture is a central library where all the books (data) are stored and managed by a single librarian (mainframe). This librarian can quickly retrieve any book, ensuring that the library operates efficiently. Similarly, a mainframe data center can quickly process and retrieve large volumes of data, ensuring high performance and reliability.
