Deploying models on cloud platforms (AWS, GCP)

In today's era of AI-driven applications, deploying machine learning models on the cloud has become essential for scalability, reliability, and improved accessibility. Cloud platforms like Amazon Web Services (AWS) and Google Cloud Platform (GCP) provide robust infrastructure and services to deploy and serve your Keras models efficiently.

Why deploy models on cloud platforms?

Deploying machine learning models on cloud platforms offers numerous benefits:

  1. Scalability: Cloud platforms provide resources that can scale up or down according to the demand, allowing you to handle a large number of requests without compromising the performance of your model.

  2. Reliability: Cloud platforms ensure high availability of your models by automatically managing the underlying infrastructure and providing features like load balancing and fault tolerance.

  3. Cost-effectiveness: With cloud platforms, you pay for the resources you use, enabling cost optimization by reducing infrastructure maintenance costs.

  4. Global accessibility: Cloud platforms have data centers worldwide, allowing you to serve your models to users across the globe with low latency.

Now, let's explore how to deploy Keras models on two major cloud platforms: AWS and GCP.

Deploying models on AWS

Amazon Web Services (AWS) offers several services to deploy models efficiently. The following steps outline a general process to deploy Keras models on AWS:

  1. Train your Keras model: Before deployment, ensure that you have trained and saved your Keras model using to serialize the model into disk format.

  2. Choose an AWS service for deployment: AWS provides various services like AWS Elastic Beanstalk, AWS Lambda, and Amazon SageMaker. Each service has different use cases and deployment methods. For example, AWS Elastic Beanstalk simplifies deploying web applications, while Amazon SageMaker provides an end-to-end ML platform.

  3. Create an AWS instance: Depending on the chosen service, you may need to create an instance or environment to host your model. This can be done through the AWS Management Console or programmatically using AWS SDKs.

  4. Upload your model: Once the instance or environment is set up, upload your trained Keras model along with any necessary dependencies.

  5. Expose your model: Configure the AWS service to expose your model through an API endpoint. This endpoint can be accessed by external applications for predictions.

  6. Test and monitor: Test your deployed model and monitor its performance using AWS monitoring tools. Make necessary adjustments to optimize performance and handle updates.

Deploying models on GCP

Google Cloud Platform (GCP) offers several services to deploy and serve your Keras models seamlessly. Here's a general process to deploy Keras models on GCP:

  1. Train your Keras model: Train and save your Keras model using the method.

  2. Choose a GCP service for deployment: GCP offers services like Google Cloud Functions, Google App Engine, and Google Cloud AI Platform for deploying ML models. Each service caters to different deployment requirements.

  3. Create a GCP project: Set up a GCP project and enable necessary APIs to use the desired service for model deployment.

  4. Deploy your model: Depending on the chosen service, deploy your Keras model by either uploading it directly or specifying the location of the serialized model file.

  5. Set up an endpoint: Configure your deployment to create an endpoint (e.g., in Cloud Functions) or an application URL (e.g., in App Engine) to access your model.

  6. Monitor and optimize: Monitor the performance of your deployed model using GCP's monitoring tools. Scale up or down the resources as per the demand and make necessary optimizations.


Deploying Keras models on cloud platforms like AWS and GCP plays a critical role in making your machine learning models accessible, scalable, and reliable. With powerful services provided by these platforms, you can easily deploy your trained models, expose them through APIs, and monitor their performance. Whether you choose AWS or GCP will depend on your specific requirements and familiarity with the platform. Happy model deployment on the cloud!
