Storage Optimized Instances

1. Introduction

Amazon EC2 (Elastic Compute Cloud) offers a variety of instance types optimized for different use cases. This lesson discusses Storage Optimized Instances, designed to deliver high storage throughput and low latency, making them ideal for data-intensive applications.

2. Key Concepts

Storage Optimized Instances are designed for applications that require high, sequential read and write access to large datasets on local storage.
They provide a balance of compute, memory, and storage performance.
Instances come with a variety of non-volatile storage options, including SSDs and HDDs.
Common applications include data warehousing, Hadoop distributed computing, and large transactional databases.

3. Instance Types

Key Storage Optimized Instances include:

i3 Instances: Ideal for high I/O performance and low latency.
i3en Instances: Offer a higher storage capacity and improved cost efficiency.
d3 Instances: Provide dense storage and are suitable for large data sets and analytics workloads.

4. Use Cases

Storage Optimized Instances are best suited for:

Data Lakes and Warehousing: Efficiently storing and querying large volumes of structured and unstructured data.
Big Data Analytics: Working with large datasets using frameworks like Apache Hadoop or Apache Spark.
High-Performance Databases: Running databases that require high IOPS and low latency.

5. Best Practices

When using Storage Optimized Instances, consider the following best practices:

Choose the right instance type based on your specific workload requirements.
Utilize Amazon EBS for persistent storage, especially for data that requires durability.
Monitor performance metrics using Amazon CloudWatch to optimize resource allocation.
Consider using Auto Scaling to adjust capacity based on demand.

6. FAQ

What are the primary benefits of using Storage Optimized Instances?

Storage Optimized Instances provide high performance for data-intensive applications, low latency, and high throughput, making them ideal for specific workloads like databases and analytics.

Can I change the instance type later?

Yes, you can change the instance type by stopping your instance, changing the instance type through the AWS Management Console, and then restarting it.

How do I determine if I need a Storage Optimized Instance?

If your application requires high-speed access to large datasets, low latency, and efficient I/O operations, then a Storage Optimized Instance may be necessary.
