Hello LinkedIn community! ??
Continuing my "Learning in Public" series on AWS Cloud, today I’m exploring the storage options available for Amazon EC2 instances: Instance Stores and Amazon Elastic Block Store (EBS). Here's what you need to know:
Instance Stores:
- Temporary Storage: Provides block-level storage volumes that act like physical hard drives.
- Ephemeral: Disk storage is physically attached to the host computer for an EC2 instance and lasts only as long as the instance is running. If the instance is terminated, all data in the instance store is lost.
- Use Case: Best for temporary data that does not need to persist, such as cache or buffer storage.
Amazon Elastic Block Store (EBS):
- Persistent Storage: Offers block-level storage volumes that can be used with Amazon EC2 instances.
- Durability: Data on an EBS volume remains available even if you stop or terminate the EC2 instance.
- Configuration: You can define the configuration of your EBS volume, including size and type, and attach it to an EC2 instance.
- Backups: Essential for data that needs to persist. You can take incremental backups by creating Amazon EBS snapshots.

Why It Matters:
- Instance Stores: Ideal for temporary, high-speed storage needs. Perfect for data that doesn’t need to be saved after the instance is terminated.
- Amazon EBS: Crucial for applications requiring long-term data storage and reliability. Provides flexibility and durability for your data.
Choosing the Right Storage:
- Use Instance Stores for temporary storage needs where speed is critical.
- Opt for Amazon EBS for persistent, reliable storage with the ability to back up data via snapshots.
Understanding the strengths of each storage option helps in optimizing the performance and reliability of your applications. ????
