Which Amazon EC2 instance type is ideal for high-performance databases?Memory optimizedStorage optimizedGeneral purposeCompute optimized

To determine which Amazon EC2 instance type is ideal for high-performance databases, it's essential to understand the characteristics of each type:

1. Memory Optimized: These instances are designed for workloads that require large amounts of memory. They are suitable for databases that need to access and process large data sets quickly since they provide high memory-to-CPU ratios. This makes them ideal for in-memory databases, real-time analytics, and high-performance databases like SAP HANA.

2. Storage Optimized: These instances are optimized for workloads requiring high, sequential read and write access to very large data sets on local storage. They are suited for database workloads but typically excel in scenarios where storage I/O performance is critical.

3. General Purpose: These instances offer a balance of compute, memory, and networking resources, making them a versatile choice but not specifically optimized for high-performance database workloads.

4. Compute Optimized: These instances are tailored for compute-intensive tasks, providing enhanced processing power. They can be beneficial for applications with high computational demands but might not specifically address the needs of databases that require high memory and storage throughput.

Given the requirements for high-performance databases, the Memory Optimized instance type stands out as the most suitable option. It provides the necessary resources to manage large datasets efficiently, ensuring optimal performance for database operations.
