For customers already operating within the AWS ecosystem, choosing GPU-based instances on AWS offers a wide range of benefits that go beyond just performance. Whether you're running machine learning workloads, high-performance computing (HPC), or graphics-intensive applications, AWS provides a compelling case for keeping your GPU workloads in-house. Let’s explore the key reasons why AWS GPU-based instances stand out.
The AWS Nitro System is a foundational technology that sets AWS apart. It enhances performance, security, and scalability in ways that are critical for GPU-based workloads.
- Performance and Efficiency: Nitro offloads virtualization tasks to dedicated hardware, freeing up nearly all server resources for your applications. This means you get better performance compared to traditional hypervisors.
- Enhanced Security: With hardware-based isolation and secure boot features, Nitro minimizes the attack surface. The Nitro Security Chip locks down administrative access, reducing risks from tampering or human error.
- Rapid Innovation: Nitro enables AWS to quickly roll out new instance types tailored to specific workloads. For GPU-based instances, this means access to cutting-edge configurations optimized for AI/ML, HPC, and rendering tasks.
Security is job zero, especially when dealing with sensitive data or mission-critical applications. AWS GPU-based instances leverage the robust security features of the AWS platform.
- Isolation and Protection: Nitro Enclaves allow you to create isolated compute environments for processing highly sensitive data, such as financial transactions or healthcare records.
- Encryption Without Compromise: AWS offers high-speed encryption for data at rest and in transit without impacting performance. This ensures your data remains secure while maintaining the speed required for demanding GPU workloads.
One of the most compelling reasons to choose AWS GPU-based instances is the seamless integration with AWS's comprehensive ecosystem of services. This integration not only simplifies workflows but also eliminates the need to move data across platforms, which can be costly, time-consuming, and prone to inefficiencies.
AWS services like Amazon S3 and Amazon FSx for Lustre ensure that your data is readily accessible and optimized for GPU workloads without requiring complex data migrations:
- Amazon S3 provides scalable, secure storage that integrates directly with compute services, enabling GPU workloads to access data efficiently.
- Amazon FSx for Lustre accelerates compute-intensive tasks by offering up to 12x higher throughput (up to 1,200 Gbps) per client instance through support for Elastic Fabric Adapter (EFA) and NVIDIA GPUDirect Storage (GDS). This ensures high-speed access to massive datasets directly from storage without unnecessary data movement.
Keeping data close to where it is processed—also known as data locality—is a critical performance advantage:
- Reduced Latency: By minimizing data movement, tasks are processed faster, reducing network congestion and latency. This is especially beneficial for AI/ML workloads that require rapid iteration and real-time processing.
- Cost Savings: Avoiding data transfers between systems or providers reduces egress costs and operational overhead.
- Regulatory Compliance: For industries like healthcare or finance, where data residency is crucial, AWS Local Zones allow you to process data locally while maintaining compliance with regulations.
AWS continuously evolves its GPU instance offerings to provide customers with cutting-edge hardware for a diverse range of workloads, from ML and HPC to graphics rendering and generative AI. By leveraging the latest GPUs, high-bandwidth networking, and scalable configurations, AWS ensures that customers stay ahead of the curve.
AWS GPU instances feature advanced networking capabilities such as EFA, delivering bandwidths up to an unprecedented 3,200 Gbps, enabling faster data transfer between nodes in distributed training environments.
AWS offers a wide range of GPU configurations—from single-GPU instances like G5.xlarge for smaller tasks to multi-GPU setups like P5en.48xlarge for the most demanding workloads—allowing you to scale resources based on your needs.
With access to NVIDIA’s latest GPUs (A10G, L4, L40S, A100, H100, H200), AWS ensures customers can leverage the best-in-class hardware optimized for deep learning, HPC simulations, graphics rendering, and generative AI.
AWS Trainium and Inferentia are custom-designed machine learning chips that enable businesses to train and deploy AI models faster, more efficiently, and at lower costs. These chips are purpose-built for the demands of generative AI (GenAI), large language models (LLMs), and other deep learning workloads.
- Cost Savings: Both chips significantly reduce costs for training and inference compared to GPUs.
- Integration with AWS Ecosystem: Fully supported by the AWS Neuron SDK, these chips integrate seamlessly with frameworks like PyTorch and TensorFlow, as well as services like Amazon SageMaker.
AWS provides flexible pricing models that help you optimize costs without sacrificing performance.
Volume Discounts: If you're running large-scale GPU workloads, you can benefit from volume discounts that make AWS even more cost-effective.
You can reserve GPU-based instances on AWS using several options, including On-Demand Capacity Reservations and Capacity Blocks for ML. These methods provide flexibility and assurance for accessing GPU resources based on your workload needs.
Capacity Blocks for ML allow you to reserve highly sought-after GPU instances on a future date to support your short duration machine learning (ML) workloads. Instances that run inside a Capacity Block are automatically placed close together inside Amazon EC2 UltraClusters, for low-latency, petabit-scale, non-blocking networking. With Capacity Blocks, you can see when GPU instance capacity is available on future dates, and you can schedule a Capacity Block to start at a time that works best for you. When you reserve a Capacity Block, you get predictable capacity assurance for GPU instances while paying only for the amount of time that you need. Reservation durations for 1-day increments up 14 days and 7-day increments up to 182 days total. Capacity Blocks is really cost effective and a highly recommended path for your short duration workloads.
AWS GPU instances, Trainium, and Inferentia collectively empower you to tackle the most demanding AI, ML, and HPC workloads with cutting-edge hardware and purpose-built chips. By staying within the AWS ecosystem, customers benefit from seamless integration, reduced data movement, cost efficiency, and access to the latest innovations—enabling you to accelerate innovation and scale your AI applications with confidence.
