Accelerate Workload Migration And Modernization Flashcards
You are using a database engine on-premises that is not currently supported by RDS. If you wish to bring your database to AWS, how do you migrate it?
AWS has two tools to help you migrate your database workloads to the cloud: database migration service and schema conversion tool. First, collect information on your source database and have SCT convert your database schema and database code. You may check the supported source engines here. Once the conversion is finished, you can launch an RDS database and apply the converted schema, and use database migration service to safely migrate your database.

You have thousands of applications running on premises that need to be migrated to AWS. However, they are too intertwined with each other and may cause issues if the dependencies are not mapped properly. How should you proceed?
Use AWS Application Discovery Service to collect server utilization data and perform dependency mapping. Then send the result to AWS Migration Hub where you can initiate the migration of the discovered servers.
You have to migrate a large amount of data (TBs) over the weekend to an S3 bucket and you are not sure how to proceed. You have a 500Mbps Direct Connect line from your corporate data center to AWS. You also have a 1Gbps Internet connection. What should be your mode of migration?
One might consider using Snow hardware to perform the migration, but the time constraint does not allow you to ship the hardware in time. Your Direct Connect line is only 500Mbps as well. So you should instead enable S3 Transfer Acceleration and dedicate all your available bandwidth for the data transfer.
You have a custom-built application that you’d like to migrate to AWS. Currently, you don’t have enough manpower or money to rewrite the application to be cloud-optimized, but you would still like to optimize whatever you can on the application. What should be your migration strategy?
Rehosting is out of the question since there are no optimizations done in a lift-and-shift scenario. Re-architecting is also out of the question since you do not have the budget and manpower for it. You cannot retire nor repurchase since this is a custom production application. So your only option would be to re-platform it to utilize scaling and load balancing for example.
How can you leverage AWS as a cost-effective solution for offsite backups of mission-critical objects that have short RTO and RPO requirements?
For hybrid cloud architectures, you may use AWS Storage Gateway to continuously store file backups onto Amazon S3. Since you have short RTO and RPO, the best storage type to use is File Gateway. File Gateway allows you to mount Amazon S3 onto your server, and by doing so you can quickly retrieve the files you need. Volume Gateway does not work here since you will have to restore entire volumes before you can retrieve your files. Enable versioning on your S3 bucket to maintain old copies of an object. You can then create lifecycle policies in Amazon S3 to achieve even lower costs.
You have hundreds of EC2 Linux servers concurrently accessing files in your local NAS. The communication is kept private by AWS Direct Connect and IPsec VPN. You notice that the NAS is not able to sufficiently serve your EC2 instances, thus leading to huge slowdowns. You consider migrating to an AWS storage service as an alternative. What should be your service and how do you perform the migration?
Since you have hundreds of EC2 servers, the best storage for concurrent access would be Amazon EFS. To migrate your data to EFS, you may use AWS DataSync. Create a VPC endpoint for your EFS so that the data migration is performed quickly and securely over your Direct Connect.
If you have a piece of software (e.g. CRM) that you want to bring to the cloud, and you have an allocated budget but not enough manpower to re-architect it, what is your next best option to make sure the software is still able to take advantage of the cloud?
Check in the AWS Marketplace and verify if there is a similar tool that you can use – Repurchasing strategy.
