07 - Migration and Transfer

Question 1

AWS Snowball (Edge)
• Physical data transport solution: move TBs or PBs of data in or out of AWS

Answer 1

1) Alternative to moving data over the network (and paying network fees)
2) Pay per data transfer job
3) Provide block storage and Amazon S3-compatible object storage
4) Snowball Edge Storage Optimized
• 80 TB of HDD capacity for block volume and S3 compatible object storage
5) Snowball Edge Compute Optimized
• 42 TB of HDD capacity for block volume and S3 compatible object storage
6) Use cases: large data cloud migrations, DC decommission, disaster
recovery

Question 2

AWS Snowcone

• Small, portable computing, anywhere, rugged & secure, withstands harsh environments

Answer 2

• Light (4.5 pounds, 2.1 kg)
• Device used for edge computing, storage, and data transfer
• 8 TBs of usable storage
• Use Snowcone where Snowball does not fit (space-constrained environment)
• Must provide your own battery / cables
• Can be sent back to AWS offline, or connect it to internet and use AWS DataSync to send data

Question 3

AWS Snowmobile

• Transfer exabytes of data (1 EB = 1,000 PB = 1,000,000 TBs)

Answer 3

• Each Snowmobile has 100 PB of capacity (use multiple in parallel)
• High security: temperature controlled, GPS, 24/7 video surveillance
• Better than Snowball if you transfer more than 10 PB

Question 4

AWS Transfer Family

• A fully-managed service for file transfers into and out of Amazon S3 or Amazon EFS using the FTP protocol

Answer 4

• Supported Protocols
  
  • AWS Transfer for FTP (File Transfer Protocol (FTP))
  • AWS Transfer for FTPS (File Transfer Protocol over SSL (FTPS))
  • AWS Transfer for SFTP (Secure File Transfer Protocol (SFTP))
• Managed infrastructure, Scalable, Reliable, Highly Available (multi-AZ)
• Pay per provisioned endpoint per hour + data transfers in GB
• Store and manage users’ credentials within the service
• Integrate with existing authentication systems (Microsoft Active Directory, LDAP, Okta, Amazon Cognito, custom)
• Usage: sharing files, public datasets, CRM, ERP, …

Question 5

AWS Database Migration Service (AWS DMS)

Answer 5

• Quickly and securely migrate databases to AWS, resilient, self healing
• The source database remains available during the migration
• Supports:
  
  • Homogeneous migrations: ex Oracle to Oracle
  • Heterogeneous migrations: ex Microsoft SQL Server to Aurora
• Continuous Data Replication using CDC
• You must create an EC2 instance toperform the replication tasks

Question 6

AWS DataSync

Answer 6

• Move large amount of data from on-premise to AWS
• Can synchronize to: Amazon S3 (any storage classes – including Glacier), Amazon EFS, Amazon FSx for Windows
• Move data from your NAS or file system via NFS or SMB
• Replication tasks can be scheduled hourly, daily, weekly
• Leverage the DataSync agent to connect to your systems
• Can setup a bandwidth limit
