Amazon AWS Certified Solutions Architect - Professional SAP-C02 Bundle

This alternative, Choose refactor or re-architect with staged service extraction, is appropriate when A monolithic application must be decomposed into independent event-driven services to meet new business goals. Refactoring changes the architecture rather than merely the host or runtime.

Choose repurchase or replace with the approved SaaS offering solves the related scenario A redundant internal reporting tool has been superseded by an approved third-party SaaS; replacing an application with SaaS avoids migrating its custom software stack.

Although Choose rehost and use an appropriate server migration mechanism can be valid when A legacy VM can run unchanged on EC2 and must move rapidly with little application change, it targets a different technical condition. Rehosting keeps application architecture largely intact while changing infrastructure location.

Classify workloads by business criticality, downtime tolerance and technical readiness solves the related scenario An on-premises hypervisor inventory includes idle VMs and business-critical ones without grouping; readiness classification avoids treating all discovered virtual machines as equal migration candidates.

Evaluate licensing and support constraints before finalizing the target AWS deployment would address a different requirement: An application has no source-code owner and a contractual software license tied to one data center. License transfer and supportability are hard constraints beyond server capacity.

This alternative, Run database compatibility assessment with AWS Schema Conversion Tool, is appropriate when A SQL Server application uses unsupported proprietary stored procedures that may fail on PostgreSQL. Schema analysis identifies conversion gaps before choosing a different database engine.

License transfer and supportability are hard constraints beyond server capacity.

This alternative, Assess dependency topology, data gravity, compliance and nonfunctional objectives together, is appropriate when Application owners estimate migration effort from CPU utilization alone and ignore database connections. Infrastructure size alone cannot predict application migration complexity.

For the separate situation A hybrid application has high east-west traffic and moving one tier first would add excessive latency, Assess traffic dependency and move tightly coupled components in the same migration wave could be useful. Data and call-path latency can invalidate a superficially simple phased move.

Although Model hybrid transfer fees and network latency before selecting the migration sequence can be valid when An application will send terabytes of traffic back to on-premises after migration, it targets a different technical condition. Ongoing hybrid data movement can dominate cloud operating cost.

Include temporary dual-run periods and postcutover decommissioning milestones in cost models would address a different requirement: A proposed migration claims savings despite permanent double-running of source and target databases. Overlap and delayed shutdown can reverse expected cost benefits.

For the separate situation A database workload is moved to a managed service and business owners ask about qualitative benefits, Include patching effort, availability operations and resilience benefits alongside cost in the assessment could be useful. Managed service value includes reduced operational toil beyond instance-hour charges.

Build a multi-year TCO comparing infrastructure, licensing, operations, transfer and exit costs would address a different requirement: A migration business case considers EC2 price but excludes existing colocation termination penalties. A valid business case accounts for one-time and recurring source and target costs.

Managed service value includes reduced operational toil beyond instance-hour charges.

Attribute short-lived migration tooling and support costs separately from steady-state infrastructure solves the related scenario A one-time migration requires purchasing a new replication license that will be retired after cutover; one-off transition expenses should not be mistaken for permanent target run rate.
