In this blog, we will cover the Q&As from Day 5 of Migrate Apps & Database to Cloud (AWS Workshop) covering Data Migration to AWS FAQs. This blog will help you to get started with Data Migration to AWS.
In this session, We covered Module 5: Data Migration to AWS which covers the following objectives.
[Q/A] Related to Data Migration to AWS
Q1: What does data migration mean?
Ans: Data migration is the process of moving data from one location, one format, or one application to another. This typically occurs when a new data system or storage location is implemented.
Q2: How do I use AWS Database Migration Service with other applications?
Ans: AWS Database Migration Service offers a provisioning API that enables you to script the generation of replication tasks at predetermined periods throughout the day or to create them straight from your development environment.
Developers and database administrators can automate replication task creation, restart, administration, and termination using the service API and CLI.
Q3: What source databases and target databases does AWS Database Migration Service support?
Ans: Numerous homogeneous and heterogeneous data replications are supported by AWS Database Migration Service (DMS).
Both the source and the target databases (or just one of them) must be located on EC2 or RDS. On-premises to on-premises database replication is not supported.
Q4: How is AWS Schema Conversion Tool (SCT) and AWS Database Migration Service (DMS) related?
Ans: DMS and SCT cooperate to allow continuing replication for a variety of functions, including populating data lakes and warehouses, synchronizing systems, etc., when SCT is chosen over the built-in DMS Schema Conversion capability. Database schemas for homogeneous migrations can be copied and converted for heterogeneous migrations using SCT. The schemas may be between data warehouses or databases (for instance, Oracle and PostgreSQL) (for example, Netezza to Amazon Redshift).
Q5: What are the Data Migration Services in AWS?
Ans:
- Direct Connect
- AWS Snowball
- AWS Snowmobile
- S3 Transfer Acceleration
- Storage Gateway
- Snowball Edge
- Kinesis Firehouse
Q6: What is AWS Snowball?
Ans: With the help of the AWS Snowball service, you can transport data into and out of AWS and extend AWS computation and storage capabilities to your edge locations. These tough devices are also known as AWS Snowball Edge devices or AWS Snowball devices. AWS Snowball used to particularly refer to an outdated hardware model of these devices, but that model has since been replaced. Snowball Edge devices, which have onboard computer and storage capabilities, are currently used to run the AWS Snowball service.
Q7: What distinguishes hosted connections from dedicated connections?
Ans: A dedicated connection is formed using a single customer-specific 1 Gbps, 10 Gbps, or 100 Gbps Ethernet connector. Hosted connections are sourced from an AWS Direct Connect Partner that has a network link between themselves and AWS.
Q8: What is an AWS Direct Connect gateway?
Ans: Virtual private gateways (VGWs) and private virtual interfaces make up an AWS Direct Connect gateway (VIFs). An AWS Direct Connect gateway is a resource that is accessible anywhere. An AWS Direct Connect gateway is a resource that is accessible anywhere. You can create the AWS Direct Connect gateway in any Region and access it from all other Regions.
Q9: What use cases does AWS Storage Gateway support?
Ans: Storage Gateway supports four key hybrid cloud use cases – (1) move backups and archives to the cloud, (2) reduce on-premises storage with cloud-backed file shares, (3) provide on-premises applications with low-latency access to data stored in AWS, and (4) data lake access for pre and post-processing workflows.
Q10: After migration, what happens to the Agent on my old System?
Ans: The migration process deactivates the Agent on the old computer so it no longer backs up files. If your old computer is still operational and you log on to it, the Agent starts but does not process files. In addition, the process permanently deletes the old computer from your profile, which removes your access to it from other Connected applications.
Q11: Can I block specific data from replicating in my warehouse?
Ans: Yes, you can block both specific tables and specific columns. This is especially helpful for sensitive information such as personally identifiable information (PII).
Q12: Can I replicate data from encrypted data sources?
Ans: Yes, AWS Database Migration Service can read and write from and to encrypted databases. AWS Database Migration Service connects to your database endpoints on the SQL interface layer. If you use the Transparent Data Encryption features of Oracle or SQL Server, AWS Database Migration Service will be able to extract decrypted data from such sources and replicate it to the target.
