Question #717
A global financial services firm is migrating most applications to AWS but must retain some applications within its own data centers due to strict data sovereignty regulations and latency requirements of under 5 milliseconds. Additionally, the firm operates branch offices in remote locations with unreliable network infrastructure and needs to host certain workloads there. The company requires a consistent development environment to enable its developers to deploy applications seamlessly across on-premises, cloud, and edge locations using the same tooling and APIs. Which solution meets these requirements?
Migrate all compliant workloads to the nearest AWS Region. Establish AWS Direct Connect between the on-premises data center and AWS. Use AWS Local Zones for latency-sensitive applications and deploy AWS Outposts in branch offices.
Deploy AWS Snowball Edge Storage Optimized devices for applications requiring data residency or low latency. Use AWS Outposts for workloads in branch offices and migrate remaining applications to AWS Wavelength Zones.
Install AWS Outposts for applications requiring data sovereignty or ultra-low latency. Deploy AWS Snowball Edge Compute Optimized devices to host workloads in remote branch offices with limited connectivity.
Migrate latency-sensitive applications to AWS Wavelength. Retain data-regulated applications in the on-premises data center using AWS Outposts and deploy AWS Local Zones in branch offices.
Explanation
Answer C is correct because:
1. AWS Outposts provides AWS infrastructure/services on-premises, ensuring compliance with data sovereignty regulations and meeting ultra-low latency (<5ms) requirements.
2. AWS Snowball Edge Compute Optimized devices are ideal for remote branch offices with unreliable networks, enabling local workload hosting without dependency on continuous connectivity.
3. Both services integrate with AWS APIs/tooling, ensuring a consistent development environment across on-premises, cloud, and edge.
Why other options are incorrect:
- A: Local Zones are AWS-managed extensions, not on-premises, and Outposts in branches may be excessive.
- B: Snowball Edge Storage Optimized is unsuitable for compute workloads; Wavelength targets 5G mobile edge, not remote branches.
- D: Wavelength is for telecom-integrated latency, not on-premises needs; Local Zones are not deployable in branches.
Key Points:
- Use Outposts for on-premises data sovereignty/low latency.
- Use Snowball Edge Compute for edge locations with poor connectivity.
- Ensure AWS-native APIs/tooling consistency across environments.
Answer
The correct answer is: C
