Performance Tuning Mechanisms for EBS Volumes
Question
You are working as an architect in your organization's Linux environment.
An application team uses EBS volume for their database workloads which would need a high throughput, low latency and maximum I/O.
They chose Provisioned IOPS EBS volume for better performance.
However, after setting up the entire application, they notice the performance is not up to the mark.
Which performance tuning mechanisms would you suggest? Please choose 3 correct options.

Sure, I'd be happy to provide a detailed explanation of the correct options for performance tuning in this scenario.
The application team has already chosen Provisioned IOPS EBS volumes to improve performance for their database workloads, but they are experiencing suboptimal performance even after setting up the entire application. Here are the three correct options for performance tuning in this scenario:
Option A: Use EBS-Optimized Instances EBS-optimized instances are instances that are optimized for using EBS volumes and provide dedicated throughput between Amazon EC2 instances and EBS volumes. This can help to improve the performance of EBS volumes by ensuring that there is sufficient network bandwidth available for EBS I/O operations. Therefore, using EBS-optimized instances can help improve the performance of Provisioned IOPS EBS volumes in this scenario.
Option D: Use RAID 0 to Maximize Utilization of Instance Resources Using RAID 0 can help maximize the utilization of instance resources and improve the performance of EBS volumes. RAID 0 distributes data across multiple disks, which can help to increase the throughput of the storage system. By using RAID 0 with multiple EBS volumes, the application team can achieve higher performance and better utilize the resources of their EC2 instances.
Option E: Performance of Provisioned IOPS SSD volume increase with volume size. Increase EBS volume size. The performance of Provisioned IOPS SSD volumes increases with volume size. Provisioned IOPS EBS volumes are designed to provide predictable performance, but their performance is also limited by their size. By increasing the size of the EBS volume, the application team can improve the performance of the volume. Therefore, increasing the size of the EBS volume can help improve the performance of the database workloads in this scenario.
Option B: Use Throughput optimized HDD volume types for low latency and maximum I/O. This option is not correct in this scenario because the application team is already using Provisioned IOPS EBS volumes, which are designed to provide high throughput and low latency. Throughput optimized HDD volume types are designed for big data and other workloads that require high throughput, but they are not suitable for database workloads that require low latency and high I/O operations.
Option C: Use a Modern Linux Kernel. This option is not correct in this scenario because the Linux kernel version used by the application team is not likely to be the cause of suboptimal performance for their database workloads on Provisioned IOPS EBS volumes. While a modern Linux kernel can help improve overall system performance and security, it is not directly related to the performance of EBS volumes.
Therefore, the three correct options for performance tuning in this scenario are:
- Use EBS-Optimized Instances
- Use RAID 0 to Maximize Utilization of Instance Resources
- Increase EBS volume size.
