More machine learning happens on AWS than anywhere else
More customers, across a diverse set of industries, choose AWS compared to any other cloud to build, train, and deploy their machine learning (ML) applications. AWS delivers the broadest choice of powerful compute, high speed networking, and scalable high performance storage options for any ML project or application.
Every ML project is different, and with AWS, you can customize your infrastructure to fit your performance and budget requirements. From using the ML framework that works best for your team, to selecting the right hardware platform to host your ML models, AWS offers a broad choice of services to meet your needs.
Businesses have found new ways to leverage ML for recommendation engines, object detection, voice assistants, fraud detection, and more. Although the use of ML is gaining traction, training and deploying ML models is expensive, model development time is long, and procuring the right amount of infrastructure to meet changing business conditions can be challenging. AWS ML infrastructure services remove the barriers to adoption of ML by being high performing, cost-effective, and highly flexible.

The below graphic illustrates the depth and breadth of services that AWS offers. Workflow services, shown in the top layer, make it easier for you to manage and scale your underlying ML infrastructure. The next layer highlights that AWS ML infrastructure supports all of the leading ML frameworks. The bottom layer shows examples of compute, networking, and storage services that constitute the foundational blocks of ML infrastructure.
Machine learning infrastructure services
Traditional ML development is a complex, expensive, and iterative process. First, you need to prepare example data to train a model. Then, developers need to select which algorithm or framework they’ll use to build the model. Then, they need to train the model on how to make predictions, and tune it so that it delivers the best possible predictions. Finally, they need to integrate the model with their application and deploy this application on infrastructure that will scale.
Data scientists often spend a lot of time exploring and preprocessing, or "wrangling," example data before using it for model training. To preprocess data, you typically fetch the data into a repository, clean the data by filtering and modifying your data so that it is easier to explore, prepare or transform the data into meaningful datasets by filtering out the parts you don't want or need, and label the data.

After you've trained your model, you evaluate it to determine whether the accuracy of the inferences is acceptable.

Broad choice of GPU instances to optimize time and cost-to-train, available at scale
Depending on the type of machine learning application, customers prefer to optimize their development cycles to either lower the time it takes to train their ML models or lower their total cost to train. In most cases, training costs include not only the cost to train, but also the opportunity cost of idle time that ML engineers and data scientists could have spent optimizing their model.
Amazon EC2 G4 instances deliver the industry’s most cost-effective GPU platform. These instances are optimal for training less complex models and is ideal for businesses or institutions that are less sensitive to time-to-train.

Support for all major machine learning frameworks
Optimizations that plug under the frameworks
AWS Neuron is the SDK for AWS Inferentia and AWS Trainium chips. By using AWS Neuron, you can run high-performance and cost-effective ML training by using AWS Trainium-based Amazon EC2 Trn1 instances. You can also run high-performance and low-latency inference by using AWS Inferentia-based Amazon EC2 Inf1 instances. AWS Neuron is natively integrated with popular frameworks such as TensorFlow, PyTorch, and MXNet. To accelerate your training with EC2 Trn1 instances and inference with EC2 Inf1 instances, you can use your pretrained models and change only a few lines of code from within the framework.
To support efficient multi-node/distributed training, AWS has integrated Elastic Fabric Adapter (EFA) with NVIDIA Collective Communications Library (NCCL) - a library for communicating between multiple GPUs within a single node or across multiple nodes. Similar to AWS Neuron, customers can continue to use their ML framework of choice to build their models, and leverage under-the-hood optimization for AWS infrastructure.
Machine learning training and inference workloads can exhibit characteristics that are steady state (such as hourly batch tagging of photos for a large population), spikey (such as kicking off new training jobs or search recommendations during promotional periods), or both. AWS has pricing options and solutions to help you optimize your infrastructure performance and costs.
A - use Spot instances for flexible, fault tolerant workloads such as ML training jobs that are not time-sensitive
B - use On-Demand instances for new or stateful spiky workloads such as short-term ML training jobs
C - use Savings Plans for known/steady state workloads such as stable inference workloads
|Use Case||AWS Solution||How|
|Short-term training jobs||On-Demand Pricing||With On-Demand instances, you pay for compute capacity by the hour or the second depending on which instances you run.|
|Training jobs that have flexible start-stop times||Spot pricing||Amazon EC2 Spot instances allow you to request spare Amazon EC2 computing capacity for up to 90% off the On-Demand price.|
|Steady machine learning workloads over different instance types over a long period of time||Savings Plans||Savings Plans offer significant savings over On-Demand prices, in exchange for a commitment to use a specific amount of compute power for a one or three year period.|
