SageMaker Serverless Inference illustrates Amazon’s philosophy for ML workloads

We’re excited to bring Transform 2022 back to life on July 19th and virtually July 20-28. Join AI and data leaders for sensible conversations and exciting networking opportunities. Register today!

Amazon just unveiled Serverless Interface, a new option for Sagemaker, its fully powered machine learning (ML) service. The goal of Amazon Sagemaker Serverless Interface is to serve cases of use with intermittent or frequent traffic patterns, reduce the total cost of ownership (TCO) and make the service easier to use.

Amazon Sagemaker Serverless joins VentureBit, AWS VP Bretin of Machine Learning to discuss where it fits into the bigger picture of Amazon’s machine learning offerings and how it affects ease of use and TCO, as well as Amazon’s philosophy and the process of developing its machine learning. .

Amazon Sagemaker is on a constantly evolving path

Prediction is the productive phase of an ML-powered application. After creating and fine-tuning the machine learning model using historical data, it is deployed for use in production. Estimation refers to taking new data as input and generating results based on that data. For product ML applications, Amazon Notes, estimates account for up to 90% of total calculation costs.

According to Saha, serverless interface is a frequently requested feature. In December 2021, Sagemaker Serverless Inference was introduced in the preview, and is generally available today.

Serverless interface enables Sagemaker users to use machine learning models for prediction without configuring or managing the underlying infrastructure. The service is able to automatically measure provision and calculation capacity based on the volume of estimated requests. During idle time, it completely shuts down the calculation capability so that users are not charged.

This is the latest addition to Sagemaker’s options for guessing service. Sagemaker real-time interface is for workloads with low delay requirements in the order of milliseconds. Sagemaker asynchronous estimates are for estimates with large payload sizes or require a long processing time. Sagemaker batch transforms to run predictions on batches of data, and Sagemaker serverless predictions are for intermittent or frequently traffic patterned workloads.

The interface recommendation helps users in the difficult task of choosing the best of the 70 Plus available computers. Example options, and configuration management to use machine learning models for best estimate performance and cost.

Overall, reducing TCO is a top priority for Amazon, Saha said. In fact, Amazon has published a detailed analysis of Sagemaker’s TCO. According to that analysis, Amazon Sagemaker is the most cost-effective choice for end-to-end machine learning support and scalability, offering 54% lower TCO than other options in 3 years.

However, it is worth noting here what those “other options” are. In its analysis, Amazon compares Sagemaker with other self-powered cloud-based machine learning options on AWS, such as Amazon Elastic Compute Cloud EC2 and Amazon Elastic Kubernetes Service EKS. According to Amazon’s analysis, the equivalent of the services offered by Sagemaker from the beginning results in lower TCO when it results in development costs.

That may be the case, but arguably users may find it more useful to compare services offered by competitors such as Azure Machine Learning and Google Vertex AI. As far as Saha is concerned, Amazon’s TCO analysis reflects its philosophy of focusing on its users rather than competition.

According to Saha, another key part of Amazon’s philosophy is to strive to create end-to-end offerings and prioritize user needs. Product development has a customer-driven focus: customers are regularly consulted, and it is their input that prioritizes and promotes new features.

Sagemaker seems to be on a constantly evolving path, including expanding the scope in terms of the target audience. With the recent introduction of Sagemaker Canvas for no-code AI model development, Amazon also wants to enable business users and analysts to build ML-powered applications.

Amazon’s Double Bottom Line with Sagemaker Serverless Guess and Sagemaker

But what about Amazon’s double bottom line with Sagemaker – better ease of use and lower TCO?

In their analysis of Sagemaker’s new features on VentureBeat, Tianhui Michael Lee and Hugo Bowen-Anderson note that user-centric design will be key to winning the cloud race, and while Sagemaker has made significant progress in that direction, it still has a long way to go. In light of that, Amazon’s strategy of converting more EC2 and EKS users into Sagemaker and expanding the scope to include business users and analysts makes sense.

According to a 2020 paper survey, the use of Sagemaker among data scientists is 16.5%, although overall AWS usage is 48.2% (mostly through direct access to EC2). At this point, it just seems like Google Cloud is providing something comparable to the serverless guesswork, through the Vertex pipelines.

At first glance, SageMaker seems more versatile in terms of supported frameworks, and more modular than Google Vertex AI – something that Saha also highlighted as an area of ​​focus. The Vertex Pipeline Sagemaker model looks similar to a building pipeline, but is end-to-end serverless.

As Lee and Bone-Anderson note, while Google’s cloud service ranks third overall (behind Microsoft Azure and AWS), it ranks second strongest for data scientists, according to a paper survey.

The introduction of serverless interface plays a role in simplifying the theme of use, as not configuring patterns is a big win. Saha told VentureBeat that it is possible to switch between different guessing options, and that is largely done by configuration.

As Saha noted, serverless interface can be used to deploy any machine learning model, whether or not it is trained on Sagemaker. Sagemaker’s built-in algorithms and machine learning framework-serving containers can be used to deploy models at serverless interface endpoints, but users can also choose to bring their own containers.

If the traffic becomes predictable and steady, users can update Sagemaker Real-Time Endpoint from Serverless Interface Endpoint without modifying their container image. Using serverless interface, users also benefit from Sagemaker’s features, including errors in built-in metrics such as invocation count, faults, latency, host metrics, and Amazon cloudwatch.

Since its preview launch, Sagemaker Serverless Infrans has added support for the Sagemaker Python SDK and model registry. The SageMaker Python SDK is an open-source library for creating and deploying ML models on SageMaker. Sagemaker Model Registry allows users to use the model in inventory, version and product.

Ease of use and TCO

Ease of use can be difficult to determine, but what about TCO? Specifically, serverless inference should reduce TCO for use cases where it makes sense. However, Amazon does not have a specific metric to release at this time. What it does have, however, is the testimonies of early adopters.

Jeff Baudier, product director of Hugging Face, reports that Amazon Sagemaker has tested the serverless interface and was able to significantly reduce the cost for intermittent traffic workloads while abstracting the infrastructure.

Amazon Sagemaker Serverless Infrans offers the best of both worlds, as it scales quickly and seamlessly during content explosions and reduces costs for frequently used models, says Lou Kratz, chief research engineer at Bazarvoice.

Sagemaker Serverless Infrans has increased the maximum concurrent insistence for GA launches from 50 to 200 at the endpoint limit during the preview, enabling the use of Amazon Sagemaker Serverless Infrans for high-traffic workloads. The service is now available in all AWS regions where Amazon SageMaker is available, except for AWS GovCloud (US) and AWS China.
