Storage-optimized instances are designed for workloads that require high, sequential read and write access to very large data sets on local storage. They are optimized to deliver tens of thousands of low latency, Random I/O operations per second (IOPS) to applications.
Types of Storage Instances
There are 3 series of storage instances
I-Series
D-Series
H-Series
I-Series:- I-Series has further 2 types of instances i.e. I3 and I3en Instances. These types of instances are well-suited for
The high-Frequency online transaction processing system (OLTP)
Relational Databases
No-SQL Databases
Distributed File System
Data Warehousing application
vCPU-> 2 to 96 cores
RAM-> 16 to 768 GB
Local Storage-> NVMe SSD
Networking Performance- 25 to 100 Gbps
Sequential Throughput
Read-> 16GB/s
Write-> 6.4GB/s (I3), 8GB/s (I3en)
D-Series:- D-series has only one type of instance named D2 Instance.
It is well-suited for
Massive Parallel Processing (MPP) data warehouse.
Map Reduce and Hadoop distributed computing.
Log or data Processing App
vCPU-> 4 to 36 cores
RAM-> 30.5 to 244GB
Storage-> SSD
H-Series:- This family features up to 16 TB of HDD-based local storage high disk throughput and a balance of computing and Memory. There is only one instance in this family named H1 instance. It is majorly used for
App requiring sequential access to large amounts of data on direct-attached instance storage.
An app that requires high throughput access to large quantities of data.
vCPU-> 8 to 64 cores
RAM->32 to 256GB
Storage-> SSD
