Aws Elastic Block Storage
3 likes1,797 views
Elastic Block Storage (EBS) is a storage service from AWS that provides persistent block storage volumes for use with EC2 instances. EBS volumes behave like physical hard drives attached to instances and can be mounted, formatted, etc. EBS volumes are available in different types (SSD, magnetic) with varying performance characteristics and pricing. EBS snapshots provide point-in-time copies of volumes stored in S3 for backup/disaster recovery. An upcoming related service is Elastic File System (EFS) which provides a common file system accessible to multiple EC2 instances.

Aws Elastic Block Storage
- 1. Elastic Block Storage AN AWS STORAGE SERVICE SUBMITTED BY: DHANANJAY ALOORKAR
- 2. Agenda Introduction to EBS Working of EBS Benefits EBS volume types EBS Snapshots Pricing Upcoming facilities
- 3. Introduction to EBS Elastic Block Store. Persistent and dynamic disks you can define in Amazon's EC2 compute cloud. Attach them to EC2 instances. Create using both AWS console as well as ec2 cli. Once an EBS volume has been attached to an EC2 instance it functions just like a local hard disk. Increase the durability of your EBS volumes by frequently backing up them (called snapshots). Pay for what you use.
- 4. Working of EBS You create a volume from 1GB to 16TB in size and then you mount it on a device (such as /dev/sdj) on an instance, format it, and use it. Later you can detach it and then reattach it to a different instance. One volume can be attached with one instance*.
- 5. EBS working continue EBS volumes can be managed both AWS console as well as ec2 cli. Install ec2 cli using command On windows: https://s3.amazonaws.com/aws-cli/AWSCLI64.msi On Linux: curl "https://s3.amazonaws.com/aws-cli/awscli-bundle.zip" -o "awscli- bundle.zip" unzip awscli-bundle.zip sudo ./awscli-bundle/install -i /usr/local/aws -b /usr/local/bin/aws You can also snapshot the volume at any time to S3, and if you want to restore your snapshot you can create a fresh volume from the snapshot.
- 6. EBS Benefits Scalable cost-effective Redundancy to avoid data loss even when multiple hardware failures occur. Flexible to detach and attach.
- 7. EBS Volume Types General Purpose (SSD) Volumes Provisioned IOPS (SSD) Volumes Magnetic Volumes Characteristic General Purpose (SSD) Provisioned IOPS (SSD) Magnetic Volume size 1 GiB - 16 TiB 4 GiB - 16 TiB 1 GiB - 1 TiB Maximum throughput 160 MiB/s 320 MiB/s 40-90 MiB/s IOPS performance Baseline performance of 3 IOPS/GiB (up to 10,000 IOPS) with the ability to burst to 3,000 IOPS for volumes under 1,000 GiB. See I/O Credits and Burst Performance Consistently performs at provisioned level, up to 20,000 IOPS maximum Averages 100 IOPS, with the ability to burst to hundreds of IOPS API and CLI volume name gp2 io1 standard
- 8. EBS Snapshots EBS snapshots are stored in S3. Not transferable between availability zones, but you are able to copy snapshots between zones or regions. Snapshots can also be used to create new EBS volumes or resize existing volumes. EBS snapshots are “block level incremental”.
- 9. EBS pricing Amazon EBS General Purpose (SSD) volumes $0.12 per GB-month of provisioned storage Amazon EBS Provisioned IOPS (SSD) volumes $0.138 per GB-month of provisioned storage $0.072 per provisioned IOPS-month Amazon EBS Magnetic volumes $0.08 per GB-month of provisioned storage $0.08 per 1 million I/O requests Amazon EBS Snapshots to Amazon S3 $0.095 per GB-month of data stored
- 10. Upcoming features Elastic File System With Amazon EFS, storage capacity is elastic, growing and shrinking automatically as you add and remove files, so your applications have the storage they need, when they need it. Amazon EFS is an elastic, shared file storage service for Amazon EC2, and provides a common data source for workloads and applications running on more than one instance that need to access a common file system. Using EFS AWS is looking forward to implement EBS volume accessibility over one or more than one ec2 instances flexibly.
- 11. EFS Benefits: Seamless Integration Scale Up and Down Seamlessly Fully Managed Service Share File Storage Across Instances Consistent, Scalable Performance Low Cost Highly Available and Durable Secure
- 12. EFS Pricing With Amazon EFS, you pay only for the amount of file system storage you use in GB. There is no minimum fee and no set-up costs. Pricing $0.30/GB-month
