Boost ML Model Performance with Amazon SageMaker’s Serverless Inference & Provisioned Concurrency

As Seen On


In today’s fast-paced and data-driven world, machine learning models are playing an increasingly significant role in making accurate predictions. To optimize efficiency, reliability, and responsiveness in processing realtime inference requests, it is essential to have a robust and high-performance machine learning infrastructure. Amazon SageMaker’s serverless inference enables realtime model inference requests without the need to provision compute instances or configure scaling policies, ensuring a seamless experience.

One challenge that often arises is the occurrence of “cold starts,” when serverless endpoints need to spin up compute resources to handle sudden spikes in requests. This challenge can be addressed using Amazon SageMaker provisioned concurrency, a highly effective solution for eliminating cold starts and optimizing performance.

Provisioned Concurrency and its Benefits

Provisioned concurrency can be defined as pre-allocating a certain number of compute resources for frequently-invoked serverless inference endpoints. These resources, which are dedicated to the endpoint, can handle steady-state traffic more efficiently, thus mitigating the impact of cold starts.

Using provisioned concurrency with serverless inference can provide numerous benefits, including:

  • Improved performance: By pre-allocating resources, request latency is significantly reduced, leading to a more efficient and pleasant user experience.
  • Predictable scaling: As the amount of provisioned concurrency for an endpoint is manually set, it is easier to anticipate the scaling behavior and provision resources accordingly.

Application Auto Scaling in Serverless Inference

For many applications, the demand for inference varies over time, so enabling Application Auto Scaling in SageMaker helps to scale provisioned concurrency dynamically. This ensures that the right amount of resources are available at the right time, further optimizing the performance and cost-efficiency of the serverless infrastructure.

Some advantages of using Application Auto Scaling with provisioned concurrency include:

  • Enhanced resource management: Application Auto Scaling ensures that the most appropriate number of resources are available, avoiding both over-provisioning and under-provisioning.
  • Cost savings: By scaling resources based on demand, Application Auto Scaling helps eliminate unnecessary costs associated with idle resources.

Best Practices and Recommendations

To maximize the benefits of Amazon SageMaker serverless inference and provisioned concurrency, consider the following best practices:

  • Select the appropriate memory size and max concurrency: Different workloads have varying memory and concurrency requirements, so selecting the most suitable configuration for your specific use case is essential for optimizing performance.
  • Determine the right amount of provisioned concurrency: Understanding your unique workload characteristics, such as request patterns and variability, can help you strike the right balance between ensuring optimal performance and minimizing costs.

Amazon SageMaker’s serverless inference, coupled with provisioned concurrency, offers a powerful solution to optimize machine learning model performance. By eliminating cold starts and providing predictable performance characteristics, these techniques enable data scientists, engineers, and decision-makers to deliver faster, more reliable, and cost-effective machine learning applications. Don’t hesitate to adopt these innovative techniques on your journey to build powerful and efficient machine learning models.

Up until working with Casey, we had only had poor to mediocre experiences outsourcing work to agencies. Casey & the team at CJ&CO are the exception to the rule.

Communication was beyond great, his understanding of our vision was phenomenal, and instead of needing babysitting like the other agencies we worked with, he was not only completely dependable but also gave us sound suggestions on how to get better results, at the risk of us not needing him for the initial job we requested (absolute gem).

This has truly been the first time we worked with someone outside of our business that quickly grasped our vision, and that I could completely forget about and would still deliver above expectations.

I honestly can't wait to work in many more projects together!
