Difficulty: HardAssess and Select Migration Strategy (7 Rs)

A media broadcasting company is planning to migrate its regional digital asset archiving and distribution portfolio to AWS. The portfolio consists of the following components:

1. A web ingest API tier running on custom-compiled Linux binaries that requires low-latency processing and has no source code or build pipeline documentation available.
2. A metadata database running on Microsoft SQL Server 2019 Enterprise Edition on Windows Server 2016, utilizing proprietary CLR (Common Language Runtime) integrations, which must remain on SQL Server due to vendor compliance, but needs to eliminate OS-level licensing and management overhead.
3. A cold-storage legacy tape-archiving daemon that integrates with local physical storage area networks (SAN) via proprietary Fibre Channel protocol, which must remain on-premises due to compliance and hardware dependency.

The migration must be completed within a strict three-month timeline, and the company requires minimal operational overhead for database management.

Which two of the following migration strategies correctly align with these requirements?

  1. Rehost the web ingest API tier using AWS Application Migration Service (MGN), and replatform the metadata database to Amazon RDS for SQL Server.Answer
  2. Retain the legacy tape-archiving daemon on-premises, and replatform the metadata database to Amazon RDS for SQL Server.Answer
  3. C
    Refactor the metadata database by migrating it to Amazon Aurora PostgreSQL using the AWS Schema Conversion Tool (SCT) to eliminate SQL Server licensing.
  4. D
    Replatform the web ingest API tier by containerizing the custom-compiled Linux binaries and deploying them to AWS Fargate to minimize server management.
  5. E
    Relocate the legacy tape-archiving daemon to AWS Storage Gateway Volume Gateway to eliminate physical SAN dependencies.

Answer

The correct answer is to rehost the web ingest API tier using AWS Application Migration Service (MGN) and replatform the metadata database to Amazon RDS for SQL Server, while retaining the legacy tape-archiving daemon on-premises.
The correct choices correctly identify the 7 Rs migration paths based on the constraints. First, the web ingest API tier has no source code or build documentation and must be migrated within a tight timeline, which makes a lift-and-shift (Rehost) using AWS Application Migration Service (MGN) the most appropriate choice. Second, the metadata database requires Microsoft SQL Server due to vendor compliance and proprietary CLR integrations, but the customer wants to reduce OS-level management. Migrating it to Amazon RDS for SQL Server is a Replatform strategy that meets these requirements. Third, the tape-archiving daemon has physical dependencies (Fibre Channel SAN) and compliance constraints that prevent it from being migrated, requiring it to be left on-premises under a Retain strategy.

Step-by-Step Solution

1
Analyze the constraints and characteristics of the web ingest API tier.
Identify Rehost as the correct strategy.
Because there is no source code or build pipeline documentation available, and the migration timeline is limited to three months, containerizing or refactoring is high-risk. A direct lift-and-shift (Rehost) using AWS Application Migration Service (MGN) is required.
2
Analyze the metadata database requirements and constraints.
Identify Replatform (Amazon RDS for SQL Server) as the correct strategy.
Vendor compliance mandates SQL Server, and proprietary CLR integrations are used, ruling out database engine refactoring. The requirement to eliminate OS-level management and licensing overhead points to a managed service, making Amazon RDS for SQL Server (Replatform) the optimal choice.
3
Analyze the legacy tape-archiving daemon requirements.
Identify Retain as the correct strategy.
The daemon has physical hardware dependencies (Fibre Channel SAN) and compliance constraints requiring it to remain on-premises, meaning it cannot be migrated to AWS.
4
Match the identified strategies to the options.
Select the correct combination options.
The options containing the API rehost, the daemon retention, and the database replatform correctly reflect these valid migration decisions.
