No-Cost Services for Migrating On-Premises Blog Application to AWS
Question
The company you are working for has an on-premises blog web application, which is built on VMware vSphere virtual machines.
As an AWS solutions architect, you need to evaluate the proper methods to migrate the application to AWS.
After the initial analysis, you have suggested using AWS Server Migration Service (SMS) to migrate.
During this migration process, which AWS services will NOT bring extra costs? (Select TWO.)

A. B. C. D. E.Correct Answer - A, D.
AWS SMS is a free service to use for the server migration which means that there is no additional fee.
However, the storage resources used during the migration process, such as Amazon EBS snapshots and Amazon S3, can generate standard fees.
Refer to https://docs.aws.amazon.com/server-migration-service/latest/userguide/server-migration.html for the introductions to AWS SMS.
Option A is CORRECT: Because the Server Migration Connector is a pre-configured FreeBSD virtual machine available for deployment in the VMware environment.
Option B is incorrect: Because during the migration, there is a step to convert the VMDK to an Amazon Elastic Block Store (Amazon EBS) snapshot, which generates cost.
Option C is incorrect: Because the S3 usage is charged when VMDK files are uploaded to Amazon S3.
Option D is CORRECT: Because the replication job or task itself is free to use.
Option E is incorrect: Because EC2 instances are charged at a standard rate.
Sure, I'd be happy to help you with that!
In this scenario, the company's on-premises blog web application is built on VMware vSphere virtual machines, and you've suggested using AWS Server Migration Service (SMS) to migrate it to AWS.
During this migration process, there are certain AWS services that will NOT bring extra costs. Let's discuss each of the options:
A. The Server Migration Connector downloaded from AWS: When you use AWS Server Migration Service (SMS), you'll need to install a connector on your on-premises servers, which will communicate with the SMS service. This connector is downloaded from AWS, but it won't incur any additional costs.
B. Amazon EBS snapshots generated during the migration: Amazon Elastic Block Store (EBS) provides block-level storage volumes for use with Amazon EC2 instances. During the migration process, AWS Server Migration Service creates Amazon EBS snapshots of your on-premises servers. However, these snapshots will incur additional costs.
C. Amazon S3 which is used to store the uploaded VMDK: During the migration process, you'll need to upload the VMDK files to AWS. AWS Server Migration Service uses Amazon S3 to store the uploaded VMDK files. However, standard Amazon S3 pricing applies to this storage, so it will incur additional costs.
D. The replication job that is created in Server Migration Service: When you create a replication job in AWS Server Migration Service, you're basically defining the settings for how your on-premises servers will be migrated to AWS. Creating a replication job won't incur any additional costs.
E. The EC2 instances that run based on the new AMI: After the migration is complete, you'll have new Amazon EC2 instances running in AWS, based on the new Amazon Machine Image (AMI) that was created during the migration process. These instances will incur additional costs, based on the instance type, region, and usage.
So, based on the above discussion, options A and D are the correct answers. The Server Migration Connector downloaded from AWS and the replication job created in Server Migration Service won't incur any additional costs.
