This flexibility is beneficial for companies that experience varying demands throughout the year.
Different Types of Instances
AWS EC2 instances suitable for databases typically have high memory, CPU, or I/O capabilities. Here are some instance types that are suitable for running databases with a focus on balancing performance and cost:
- Amazon EC2 R5 instances are optimized for memory-intensive workloads and offer up to 768 GB of memory. As a result, they are suitable for databases that require large amounts of memory to perform well.
- Amazon EC2 M5 instances: These instances are optimized for general-purpose workloads and offer a balance of CPU and memory. They are a good choice for databases that require a balance of computing and memory resources.
- Amazon EC2 C5 instances are optimized for compute-intensive workloads and offer up to 96 vCPUs. As a result, they are a good choice for databases that require high CPU performance.
- Amazon EC2 I3 instances are optimized for I/O-intensive workloads and offer high-speed NVMe-based SSDs for local storage. As a result, they are a good choice for databases that require high I/O performance.
- Amazon EC2 T3 instances: These instances are cost-effective for databases that do not require consistently high performance. They offer a balance of CPU and memory resources at a low cost.
It is important to note that the optimal instance type for a particular database workload will depend on the specific requirements of that workload. Therefore, it is essential to carefully evaluate the needs of your database workload before selecting an instance type.
AWS Recommendations
AWS does not recommend a specific instance type for databases, as the optimal instance type will depend on the particular requirements of the workload.
However, AWS guides on selecting the appropriate instance type for different types of workloads, including databases.
In general, AWS recommends selecting an instance type with sufficient CPU, memory, and storage resources to meet the workload’s performance requirements while considering cost considerations.
