Many data scientists use the hosted environment to build, train, and deploy machine learning models. Unfortunately, they lacked the ability to increase or decrease resources as needed.
AWS SageMaker solves this problem by allowing developers to build and train models to get to production faster and at a lower cost.
And before we get started with SageMaker, here’s an overview of “What is AWS?”
What is AWS?
Amazon Web Services (AWS) is a cloud platform that provides on-demand services over the Internet. AWS services can be used to design, monitor, and deploy any form of cloud application. This is where AWS SageMaker comes in.
Good!! so let’s get into the AWS Sagemaker tutorial
Want to learn more about AWS, here is a video for you
AWS SageMaker Definition
Amazon SageMaker is a cloud-based machine learning platform that enables users to construct, design, train, tune, and deploy machine learning models in a hosted, production-ready environment. AWS SageMaker has many advantages (learn all about it in the next section).
Machine learning offers a wide range of applications and benefits. Advanced analytics for customer data and back-end security threat detection are two examples.
Even experienced application developers find it difficult to implement ML models. Amazon SageMaker tries to make the process easier. It accelerates the machine learning process by using standard algorithms and other resources.

Working on AWS SageMaker
Machine learning modeling is divided into three parts in AWS SageMaker: preparation, training, and deployment.
Prepare and construct AI models
Amazon SageMaker runs a fully managed machine learning instance on Amazon Elastic Compute Cloud (EC2). It is compatible with the free online Jupyter Notebook application, which allows developers to exchange code live. SageMaker uses Jupyter notebooks to perform computational tasks.
Notebooks offers drivers, packages, and libraries for popular deep learning platforms and frameworks. Developers can use AWS to deploy a pre-built laptop for a range of applications and use cases. They can then tailor it to the data collection and schema to be trained.
Developers can also use custom algorithms written in one of the supported ML frameworks or any code packaged as a Docker container image. SageMaker can receive data from Amazon Simple Storage Service (S3) and there is no practical limit to the amount of data collected.
To get started, the developer connects to the SageMaker console and opens a notebook instance. SageMaker comes with several built-in training algorithms, including linear regression and image classification, or the developer can import unique methods.
Set up and practice
Model training developers specify the location of the data in an Amazon S3 bucket, as well as the appropriate instance type. Then they start the training procedure.
SageMaker Model Monitor offers continuous automated model tuning to find the optimal collection of parameters or hyperparameters. Data is modified at this stage to enable feature engineering.
Deploy and analyze
When the model is ready for deployment, the service manages and scales the cloud infrastructure automatically. It uses a collection of SageMaker instance types that contain multiple GPU accelerators designed for ML applications.
SageMaker deploys to multiple Availability Zones, performs health checks, installs security updates, configures AWS auto-scaling, and creates secure HTTPS endpoints to connect to an application.
A developer can use Amazon CloudWatch metrics to track and alert on changes in production performance.
Features of Amazon SageMaker
SageMaker has acquired more features from Amazon since its initial release in 2017. Functionalities are available in AWS SageMaker Studio, an integrated development environment (IDE) that combines all capabilities.
Users can create a Jupyter notebook in two ways:
- in Amazon SageMaker as an ML instance powered by Amazon EC2; or
- in SageMaker Studio as a web-based instance of the IDE
AWS SageMaker Studio’s automation capabilities allow users to automatically debug, maintain, and track ML models. The following SageMaker tools are included:
- Autopilot allows AI models to be trained on a specific set of data and evaluates each algorithm in terms of accuracy.
- Clarifying and detecting possible biases that can distort machine learning models.
- Data Wrangler is a tool to accelerate data preparation.
- The debugger monitors neural network metrics to facilitate debugging.
- Edge Manager provides machine learning monitoring and administration on edge devices.
- Experiments make it easy to track different ML iterations, such as how modifications affect model accuracy.

Machine Learning in AWS SageMaker
Machine learning is an iterative method. Processing data collections requires workflow tools and specialized hardware. A data science team typically builds ML models in two stages or pipelines: training and inference.
Data training instructs a computer to operate in a certain way based on repeated identification of patterns in data sets. The data is then inferred or trained to fit new data patterns.
After data scientists refine the ML model, software development teams translate the completed model into product or service application programming interfaces (APIs).
Many businesses do not have the funds to hire professionals and allocate resources to AI development. AWS SageMaker uses integrated technologies to automate time-consuming manual procedures while reducing human error and hardware costs.
The AWS SageMaker toolkit contains ML modeling components. In SageMaker templates, software functions are abstracted. They provide a platform to build, host, train and deploy machine learning models at scale on Amazon’s public cloud.

Amazon SageMaker Use Cases
AWS SageMaker has a wide range of industrial applications. SageMaker is used by data science teams to do the following:
- Access and distribution of code
- Speed up the creation of AI modules;
- Improve training and data inference
- Iterate to create more accurate data models
- Improve data reception and output
- Massive data sets to be processed; and
- Exchange Modeling Code
Benefits of AWS SageMaker
Following are some of the benefits of SageMaker:
- It boosts the results of a machine learning project.
- It helps in creating and managing compute instances in the shortest period.
- It inspects the raw data before automatically building, deploying and training models with full visibility.
- It reduces the cost of developing machine learning models by up to 70%.
- Reduces the time required for data labeling activities.
- Makes it easy to store all ML components in one place.
- It is highly scalable and trains models faster.
AWS SageMaker Pricing
SageMaker has several pricing options. These are some of the plans:
Pricing is billed by the latter with this pricing plan and there is no upfront commitment or minimum fee.
With this price plan, prices are reduced by 64%. This is a flexible pricing plan that commits to regular use of SameMager for a period of one or three years.
SageMaker is free to use as this pricing plan is part of the AWS free plan. However, only limited services are provided in this free tier, such as 25 hours of ml.m5.4xlarge instance or 150,000 seconds of output duration.
For most data scientists looking to achieve a true end-to-end ML solution, AWS Sagemaker is a great value. It abstracts away a large number of software development capabilities needed to get the job done while being highly efficient, flexible and cost-effective.
Most importantly, it allows you to concentrate on core ML experiments while supplementing the other necessary capabilities with simple abstract tools comparable to our current approach.
