Overview
Amazon Elastic Block Store is a persistent, high-performance block storage service for use with Amazon EC2 instances. It acts like a virtual hard drive that can be attached to an instance to store data, run databases, or install applications, and it maintains data even after the instance is shut down. EBS provides durable and scalable storage with options for both transactional and throughput-intensive workloads.
Amazon Elastic Block Store là dịch vụ lưu trữ khối bền vững, hiệu suất cao để sử dụng với các instance Amazon EC2. Nó hoạt động như một ổ cứng ảo có thể được gắn vào instance để lưu trữ dữ liệu, chạy cơ sở dữ liệu hoặc cài đặt ứng dụng, và duy trì dữ liệu ngay cả sau khi instance bị tắt. EBS cung cấp lưu trữ bền vững và có thể mở rộng với các tùy chọn cho cả khối lượng công việc giao dịch và thông lượng cao.
Key Features
- Persistence: Data on an EBS volume remains intact even if the EC2 instance is stopped or terminated.
- Scalability: You can dynamically resize EBS volumes to increase storage capacity as your needs grow.
- Availability: EBS volumes are automatically replicated within a specific Availability Zone to protect against component failure.
- Snapshots: You can create point-in-time backups of your EBS volumes, which can be stored independently and used to restore new volumes.
- Performance: EBS offers a range of volume types, including SSD and HDD-backed options, to optimize performance for different workloads.
- SSD-backed volumes: are ideal for transactional workloads like databases and boot volumes.
- HDD-backed volumes: are suitable for throughput-intensive workloads like log processing and data warehousing.
- Flexibility: You can attach and detach volumes to different instances as needed, similar to a physical drive.
