Amazon Web Services offers two different storage services: Amazon S3 and Amazon EBS. Both are a part of AWS' cloud computing platform but they have different functions and unique characteristics. This article will examine the differences between Amazon S3 & EBS. We'll also explore their features and use cases. AWS Classes in Pune
1. Purpose of Data and Types:
Amazon S3 Amazon S3 provides object storage services that can store and retrieve all types of data including documents, images, video, backups, logs and more. It's ideal for storing large amounts of unstructured information and offers a durable and available storage option that is highly scalable. S3 organizes the data into "buckets" that can contain an unlimited number objects.
Amazon EBS Amazon EBS is a block-level storage that provides persistent storage volumes to EC2 instances (Elastic Compute Cloud). EBS, unlike S3, is a block-based storage system that provides raw block storage volumes similar to hard drives. EBS volumes can be attached to EC2 instance and used to store operating systems, applications and other data requiring high-performance and low-latency.
2. Data Access
Amazon S3 S3 offers web-based APIs that enable applications to manage and access data stored in S3 buckets. Data can be accessed anywhere that has an internet connection. It's an HTTP-based platform. S3 is ideal for situations where data is frequently accessed over the Internet, such as serving static content on websites or distributing multimedia files globally.
Amazon EBS EBS volume are directly attached to instances of EC2, making them high-performance and ideal for workloads requiring low latency. EBS volumes are accessed by EC2 instances as if they were a normal block device such as a SSD or hard drive. EBS is therefore ideal for databases and application data as well as transactional workloads.
3. Data Durability and Availability
Amazon S3 Amazon S3 has been designed to be 99.999999999% durable (11 nines), meaning that objects in S3 will not fail if they are stored there. S3 replicates data automatically across multiple devices and AWS Regions to ensure data availability, even in the event of hardware failures. AWS Course in Pune
Amazon EBS Amazon EBS offers data redundancy in an Availability Zone, but does not replicate data across multiple AZs. If an Availability Zone (AZ) fails, data in EBS volumes located within that AZ may be at risk. It is common to create EBS Snapshots and replicate them in a different AZ, or AWS Region to enhance data durability.
4. Use Cases
Amazon S3
- Storing static website content
- Media files and videos can be hosted online
- Back up and archive your data
- Content delivery and CDN origin
- Data lakes and Big Data Analytics
Amazon EBS
- Running databases (e.g. MySQL, PostgreSQL), with persistent data storage
- Hosting applications that need high-performance and low-latency storage
- Software Development and Testing Environments
- Boot volumes for EC2 instances
5. Pricing Model:
Amazon S3 : S3 prices are based on data storage, data transfers in and out and the number requests made.
Amazon EBS : EBS prices are based on the storage capacity provisioned and the number I/O operations that have been performed on volumes.
6. Snapshots and backups:
Amazon S3 S3 doesn't support snapshots natively, but versioning allows you to keep multiple versions of the same object in a bucket.
Amazon EBS : EBS can create snapshots of volumes. These are copies made at a specific point in time. Snapshots are useful for disaster recovery and backups. They can also be used to create new volumes.
7. Performance:
Amazon S3: S3 provides good performance for large-scale, sequential data access. It is not optimized to handle transactional I/O or random patterns.
Amazon EBS EBS volume offers low latency and high throughput, making it suitable for applications that need fast data access.
8. Limitations:
Amazon S3
- S3 is not a block storage service; it's an object storage service.
- For certain uses, it may have slightly longer latencies than EBS.
Amazon EBS
- EBS volumes can only be accessed by a single Availability Zone. This means that you must manage backups and replication for high availability. AWS Training in Pune
Amazon S3 and Amazon EBS are different storage services that serve specific needs. Amazon S3 is a service that provides object storage with web-based access, massive scalability and data distribution. Amazon EBS provides high-performance blocks storage volumes for EC2 instance and is better suited for applications and workloads that require low latency data access. Understanding the differences between the two services will help you make an informed decision about the storage solution that best suits your needs in the AWS environment.
