In AWS SageMaker, users have access to a range of pre-configured machine learning frameworks and built-in algorithms, including popular ones like TensorFlow, PyTorch, and scikit-learn. This simplifies the experimentation process by eliminating the need for manual setup and configuration. SageMaker offers the flexibility for users to bring their own custom algorithms and frameworks, catering to a wide range of machine learning workflows and requirements.

Being the Jupyter notebook fan. I love the same in Amazon Sagemaker. Further the selection of the multiple instances and GPUs which helps in faster execution.

I think SM approach to define functional nodes is very flexible and intuitive. It’s just create some definition on where de code will be ran (processor/estimator) and then the code, the entry and exit points (over steps on pipeline, or fit method). Estimators can also be custom, and that’s really nice. A thing that I don’t like is that the training and processing steps outputs are defined differently (I.e. on training the output is automatically stored under dir model or output data, however on processing needs to be defined on the processor spec). I understand why, but I don’t like it anyway. Nonetheless , overall I think it’s great framework to start creating some ML pipelines, and get onboard on part of an MlOps infrastructure.

Amazon Sagemaker can be used to do all of these things, to prepare the data, choose the relevant environment, then training a model and finally deploying a model, end-to-end Sagemaker supports As our computers have limited computing power which is not scaleable when required, we can use Sagemaker to provision resources for complex and high computing power required programs

Deploying a model with Amazon SageMaker is a seamless process. With just a few clicks, you can take your trained model and deploy it to a scalable and highly available endpoint, ready to serve real-time predictions. SageMaker handles all the infrastructure management, auto-scaling, and monitoring, ensuring your model performs optimally in production. This allows you to quickly bring your machine learning solutions to market and deliver value to your users without worrying about the underlying infrastructure complexities.

Data Scientists can focus on developing the model, and deploy it easily using a Sagemaker endpoint which functions similarly to an API. SageMaker will handle scaling in case of a large volume of requests. Additionally, Sagemaker supports monitoring via Cloudwatch, ensures security, optimizes performance, and managed infrastructure.

Deployment is easy, store the model in S3 and write the configuration file, which generally has information on the type of instance, memory used by the instance, etc. Then create the endpoints, which you can deploy and invoke later.

-Inference involves not just the endpoint or batch transform job definition but also additional resources for operations and monitoring. Utilize Infrastructure as Code (IaC) tools like CloudFormation, CDK, or Terraform, along with robust deployment pipelines for efficient and reliable SageMaker deployments. -SageMaker's pipeline models allow for deploying up to 7 models in sequence within a single inference resource, ideal for integrating preprocessing and postprocessing with ML models to keep inference and training parameters aligned. -SageMaker also provides built-in data capture for real-time and batch transform endpoints, crucial for monitoring model/data quality. However, it requires custom implementation for other inference types.

Amazon SageMaker streamlines deployment through multiple services. Endpoints simplify the creation and management of scalable, secure endpoints for your models. Integration with other AWS services or applications becomes seamless, enhancing the overall functionality. Batch Transform offers the capability to perform batch inference on substantial datasets without the complexities of infrastructure management or scaling. For edge devices like smartphones, tablets, or IoT sensors, Edge Manager optimizes, secures, and monitors your models on these devices, ensuring efficient and reliable performance in real-world scenarios. Clarify steps in to assist in understanding and mitigating bias and explainability issues within your models and data.

Amazon SageMaker is so much more than any one thing. This makes it’s a super powerful ‘area’ of AWS, but also a little confusing at times. SageMaker Studio is a powerful IDE for working on data science and ML tasks. And it was recently updated (again) and includes a fully hosted open source version of VSCode setup and running with all the toolkits and permissions you need to get moving quickly. That was my favourite underreported feature release from re:Invent 2023. :)

In my experience, to use Amazon SageMaker, you typically interact with it through the AWS Management Console, AWS Command Line Interface (CLI), or AWS SDKs. You'll need an AWS account to access SageMaker and pay for the resources you use, such as compute instances and storage.

Best way to try out sagemaker is to find a problem, design an approach, start building it. How do you start building it? Refer AWS Docs, AWS Blogs and most importantly AWS GitHub Pages which contains lots of information with example tutorials - Trust me, they are really useful and quick way to start implementing. Also check out Huggingface + Sagemaker GitHub Pages for HF models. My best combination is Sagemaker + HuggingFace + StepFunctions + EventBridge - We can build End to End Workflows.

AWS Sagemaker provides capability for model development, experiment tracking(metrics), feature store, model registry, model promotion & deployment , inference and finally model monitoring including data quality, model quality monitoring. It is a complete MLOPs solution and further provides LLMs available for easy deployment.

Ironically, for us it’s been most helpful as a collaboration tool for the development team to experiment with data and share findings. While there’s so much more it’s capable of, that aspect of it has moved the needle most in our organization.
