Deploying a Machine Learning Model in AWS Cloud

AWS, also known as Amazon Web Services, is a widely used cloud computing service that offers various features such as storage, analytics, application deployment, and more. It’s a platform that supports businesses in a serverless manner with flexible pay-as-you-go schemes. One of the key activities that AWS supports is machine learning modeling. AWS provides several services that can aid in the development and deployment of machine learning models. Its versatility makes it an essential choice for businesses that require scalability and speed. In this article, we will explore the process of deploying a machine learning model in the AWS cloud.

Creating an AWS Account

Before we begin the tutorial, you need to create an AWS account to access all the AWS services. For the purpose of this article, we will assume that you are using the free-tier account. Additionally, it is assumed that you have basic knowledge of Python programming language and machine learning. We will focus specifically on the model deployment process and not delve into other aspects of data science. With all this in mind, let’s start our journey of deploying your machine learning model in the AWS Cloud.

Developing the Machine Learning Model

In this tutorial, we will develop a machine learning model to predict churn using a provided dataset. The training dataset can be downloaded from Kaggle. Once we have acquired the dataset, we will create an S3 bucket in the AWS services to store the dataset.

In this article, I have named the bucket as “telecom-churn-dataset” and located it in Singapore. You can choose your own name and location, but for the purpose of this tutorial, we will use this name and location. Once you have created the bucket and uploaded the dataset, we will move on to the AWS SageMaker service. We will use the SageMaker Studio as our working environment.

If you have never used the Studio before, you need to create a domain and user before proceeding. Start by selecting the Domains option within the Amazon SageMaker Admin configurations.

Within the Domains, you will find several options. Choose the Create domain button to create a new domain.

If you want to speed up the creation process, choose the quick setup option. Once the setup is complete, you will see a new domain created in the dashboard. Select the newly created domain and click the Add user button.

Name the user profile according to your preference. Leave the execution role as it is for now, as it is automatically created during the Domain creation process. Proceed with the next steps until you reach the canvas setting.

In the canvas settings, turn off the settings that are not required for this tutorial, such as Time Series Forecasting. Once you have made the necessary changes, go to the studio selection and click on the Open studio button with the user name you just created.

Inside the Studio, navigate to the folder icon on the sidebar and create a new notebook. You can leave the settings as default for now.

Now we are ready to create our churn prediction model and deploy it as an API endpoint for production use. Let’s import the necessary packages and read the churn data.

“`python
import boto3
import pandas as pd
import sagemaker

sagemaker_session = sagemaker.Session()
role = sagemaker.get_execution_role()

df = pd.read_csv(‘s3://telecom-churn-dataset/telecom_churn.csv’)
“`

Next, let’s split the data into training and testing datasets.

“`python
from sklearn.model_selection import train_test_split

train, test = train_test_split(df, test_size=0.3, random_state=42)
“`

We will now upload the datasets to the S3 bucket.

“`python
bucket = “telecom-churn-dataset”

train.to_csv(f’s3://{bucket}/telecom_churn_train.csv’, index=False)
test.to_csv(f’s3://{bucket}/telecom_churn_test.csv’, index=False)
“`

You can now see the datasets in your S3 bucket.

Now, let’s proceed to the development of the churn prediction model and its deployment. In AWS, we commonly use the script training method for machine learning training. Therefore, we need to create a script before starting the training process. Create an additional Python file named “train.py” in the same folder.

Inside the “train.py” file, let’s set up the model development process to create the churn model. For this tutorial, we will adopt some code from Ram Vegiraju. First, import all the necessary packages for developing the model.

“`python
import argparse
import os
import io
import boto3
import json
import pandas as pd

from sklearn.ensemble import RandomForestClassifier
from sklearn.metrics import accuracy_score
import joblib
“`

Next, use the parser method to control the variables that can be input into the training process. The overall code to train the model is as follows:

“`python
if __name__ == ‘__main__’:
parser = argparse.ArgumentParser()

parser.add_argument(‘–estimator’, type=int, default=10)
parser.add_argument(‘–sm-model-dir’, type=str, default=os.environ.get(‘SM_MODEL_DIR’))
parser.add_argument(‘–model_dir’, type=str)
parser.add_argument(‘–train’, type=str, default=os.environ.get(‘SM_CHANNEL_TRAIN’))

args, _ = parser.parse_known_args()

estimator = args.estimator
model_dir = args.model_dir
sm_model_dir = args.sm_model_dir
training_dir = args.train

s3_client = boto3.client(‘s3′)
bucket = “telecom-churn-dataset”

obj = s3_client.get_object(Bucket=bucket, Key=’telecom_churn_train.csv’)
train_data = pd.read_csv(io.BytesIO(obj[‘Body’].read()))

obj = s3_client.get_object(Bucket=bucket, Key=’telecom_churn_test.csv’)
test_data = pd.read_csv(io.BytesIO(obj[‘Body’].read()))

X_train = train_data.drop(‘Churn’, axis=1)
X_test = test_data.drop(‘Churn’, axis=1)

y_train = train_data[‘Churn’]
y_test = test_data[‘Churn’]

rfc = RandomForestClassifier(n_estimators=estimator)
rfc.fit(X_train, y_train)
y_pred = rfc.predict(X_test)

print(‘Accuracy Score: ‘, accuracy_score(y_test, y_pred))

joblib.dump(rfc, os.path.join(args.sm_model_dir, “rfc_model.joblib”))
“`

Finally, we need to include four different functions that SageMaker
