AWS Classroom Series – 27/Nov/2021

On-Premise Storage Integration with AWS

• If your organiazation has to transfer a large amount of data from your data centers to AWS.
  • uploading directly to AWS might not be good choice especially if the size is greater than 10 TB
• AWS offers a couple of options throught which you can move the data to the cloud
  • AWS Storage Gateway
    • The AWS Storage Gateway (SGW) service is deployed as a virtual machine in your existing environment & this VM is called a storage gateway where you connect your existing applications/storage systems or devices to this storage gateway.
    • The storage gateway provides standard storage protocol interfaces so that apps can connect to it withot changes.
    • This gateway connects to AWS so that you can store data securely and durably in AWS S3 Glacier
    • This provides low latency access through a locl cache so your apps can casses frequently used data locally
    • Interfaces supported by Storage gateway
      • File Gateway:
        • Enables you to store or retreive objects in AWS S3 using industry standard file-protocols like NFS/SMB.
        • Files in S3 buckets can be mounted to your on-premises systems using NFS mount point.
      • Volume Gateway:
        • This gateway provides your applications wiht disk volumes using iSCSI block protocol.
        • Data written to this disk can be asyncrhonous backed up as point in time snapshots of your volumes & stored in AWS EBS snapshots
        • While connecting to block interface, you can run gateway in twom modes
          • Cached:
            • You store the data in AWS S3 and retain frequently accessed data locally
          • Stored:
            • You store you entire data set locally while performing asynchronous backups of this data in S3.
            • This mode provides inexpensive off-site backups that you can recover locally or from EC2
      • Tape Gateway:
        • This gateway provides your existing backup applications as an industry standard iSCSI-based virtual tape library (VTL).
        • You can continue using your existing backup applications. Each virtual tape is stored on S3
  • AWS Snowball and AWS Snowball Edge:
    • Snowball is an AWS import/export tool that provides a petabyte-scale data transfer service that used AWS – provided storage devices for transport
    • With snowbal customers request for snow balls, one snowballs are recieved ans setup, customers will be able to transfer 80 TB data from on-premises to Snowball via snowball client software.
    • Snowball comes with two sizes 50 TB and 80 TB
    • Snowmobile is a truck which can transfer upto 100 PB of storage
