6 Storage Gateway Common capabilities Standard storage protocols integrate with on-premises applications Local caching for low-latency access to frequently used data Efficient data transfer with buffering and bandwidth management Native data storage in AWS Stateless virtual appliance for resiliency Integrated with AWS management and security

7 File gateway On-premises file storage maintained as objects in Amazon S3 Customer Premises Application Server NFS v3 / v4.1 File Gateway HTTPS Data stored and retrieved from your S3 buckets One-to-one mapping from files-to-objects File metadata stored in object metadata S3 Standard Bucket access through IAM role you own and manage S3 Standard - Infrequent Access Use S3 Lifecycle Policies, versioning, or CRR to manage data Glacier

13 Storage Gateway Key Benefits Seamless integration across standard storage protocols Low-latency access Durability, cost, and elasticity of AWS Storage services Efficient data transfer Data encryption Integrated with AWS monitoring, management, and security

14 Storage Gateway Pricing All gateway types File Volume Tape $0.01 per GB of data written to AWS* Files stored and billed by S3 $0.023 per GB-month of volume data stored Snapshots stored and billed by EBS $0.023 per GB-month of tape data stored $0.004 per GB-month of tape data archived $0.01 per GB of data retrieved from archive * Up to a maximum of $125/month. First 100GB per gateway free.

15 Getting Started Storage Gateway AWS Storage Gateway home page: aws.amazon.com/storagegateway AWS Storage Gateway documentation: aws.amazon.com/documentation/storage-gateway/ Ready to get started? AWS Storage Gateway console: console.aws.amazon.com/storagegateway/home

16 Thanks! Simple, Secure, Cost-effective Hybrid Storage in AWS

17 Under the hood

18 File Gateway File system metadata File system metadata persisted in object user-metadata, eg. x-amz-meta-file-permissions: 0666 x-amz-meta-file-user-class: 4321 x-amz-meta-file-group-class: 42 x-amz-meta-file-created: T20:08:45+00:00 x-amz-meta-file-last-modified: T20:08:45+00:00 Configurable defaults for objects that don t have this metadata E.g. objects that were already in the bucket Changing file metadata copies the object

19 How do I monitor cache performance? CloudWatch metrics metrics for gateway CachePercentUsed CacheHitPercent CachePercentDirty High CachePercentUsed is good Once 100% will start to impact CacheHitPercent May indicate the cache is too small for the working set Writes increase CachePercentDirty Reduces size of working cache, and can reduce CacheHitPercent May indicate data not uploading to AWS quickly enough

20 How does Storage Gateway transfer data to AWS? Dirty data asynchronously uploaded to AWS Byte-level parallel upload and download Compression for tape and volume Uploaded data committed to storage resource periodically File uses multi-part PUT Tape and volume create periodic recovery points (internal snapshots) Rate of writes by application determine periodicity of commit High write rates will commit more frequently Low write rates will commit based on timer

21 How do I monitor data transfer? CloudWatch metrics for gateway and per storage resource WriteBytes ReadBytes CloudBytesUploaded CloudBytesDownloaded Application server Storage Gateway For volumes TimeSinceLastRecoveryPoint indicates how long since the last commit

22 Monitoring and Security extended to on-premises gateways CloudTrail Logging of API Calls IAM Integration for File Gateway roles
