A recent Forrester Wave assessment placed AWS at the top of the AI infrastructure category, awarding it the highest possible scores in strategy and a suite of technical criteria. Practitioners should note that this validation highlights AWS’s emphasis on flexible compute options, cost‑efficiency, and a roadmap that may affect architecture and operational decisions.
Why the Forrester Rating Matters to Engineers
The evaluation covered 13 providers and measured factors such as architecture, ecosystem, data management, training, development, operations, fault tolerance, efficiency, security, and scalability. AWS achieved perfect scores in 16 of these criteria, indicating a broad consensus that its services meet the technical expectations of demanding AI workloads. For engineers, the rating signals that AWS’s offerings are considered mature enough to support end‑to‑end AI pipelines without sacrificing performance or governance.
Architectural Implications
AWS continues to provide two proprietary silicon families—Inferentia for inference and Trainium for training—alongside standard NVIDIA GPU instances. This mix lets teams select the most cost‑effective accelerator for a given stage of the model lifecycle. The key considerations are:
- Workload‑specific selection: Use Inferentia or Trainium when the workload aligns with their performance‑price sweet spot; fall back to GPUs for peak or specialized tasks.
- Avoiding lock‑in: Because both proprietary chips and GPUs are available, architects can design pipelines that switch between them without rewriting code, preserving flexibility.
- Integration points: The chips are exposed through services such as Amazon SageMaker, meaning existing SageMaker pipelines can be extended to leverage the new hardware with minimal changes.
Implementation and Operational Considerations
From an implementation perspective, the presence of multiple accelerator types introduces a need for clear profiling and benchmarking to match workloads to the right instance type. Operationally, the Forrester report notes that AWS’s strategy includes pricing transparency and flexibility, which can simplify budgeting for elastic inference workloads that scale up and down. Teams should therefore:
- Instrument training and inference jobs to capture cost and performance metrics per accelerator.
- Leverage AWS’s managed services (e.g., SageMaker) to offload orchestration, but remain aware of the underlying compute choices.
- Plan for capacity scaling by using the elastic features of the chosen instance family, especially for high‑volume inference.
Security and Compliance Outlook
Security appears as a distinct evaluation criterion, and AWS received top marks, suggesting that its AI services meet the baseline security expectations of enterprise customers. While the source does not detail specific controls, practitioners should treat the rating as an indication that standard AWS security mechanisms (identity, encryption, network isolation) are applied to AI workloads. As a precaution, teams should still verify that data handling, model access, and endpoint protection align with internal policies.

What This Means For Practitioners
In practice, the Forrester leadership signals that AWS’s AI infrastructure is a viable default choice for both large‑scale training and elastic inference. Engineers should evaluate their current workloads against the available accelerator options, benchmark cost versus performance, and incorporate the flexibility of switching between proprietary chips and GPUs into their design. Ongoing monitoring of AWS’s roadmap—particularly updates to Trainium, Inferentia, and related managed services—will be essential to stay aligned with the evolving performance and pricing landscape.
