Amazon Web Services (AWS) is a comprehensive cloud computing platform that provides a wide range of services for building, deploying, and managing applications and data. In this blog post, we will explore some of the key features of AWS that are particularly relevant for data-intensive applications, including storage, processing, and analysis. We will also provide some example code snippets to demonstrate how to use these services in practice.
Storage
One of the most fundamental components of any data-intensive application is a reliable and scalable storage system. AWS offers a variety of storage options to suit different needs and use cases.
S3
Amazon Simple Storage Service (S3) is an object storage service that allows you to store and retrieve data from anywhere on the web. It is designed to be highly scalable, with the ability to store and retrieve any amount of data, at any time, from anywhere on the web.
S3 is a great option for storing large amounts of unstructured data, such as images, videos, audio files, and log files. It is also commonly used as a data lake, where raw data can be stored in its original format and accessed by various analytics and machine learning tools.
Here is an example of how to use the AWS SDK for Python (Boto3) to create a new S3 bucket and upload a file to it:
import boto3
s3 = boto3.client('s3')
s3.create_bucket(Bucket='my-new-bucket')
s3.upload_file(Bucket='my-new-bucket', Filename='example.txt', Key='example.txt')
EBS
Amazon Elastic Block Store (EBS) is a block-level storage service that provides persistent storage for Amazon Elastic Compute Cloud (EC2) instances. EBS volumes can be attached to and detached from EC2 instances as needed, making it easy to scale up or down based on the needs of your applications.
EBS is a good choice for storing data that requires fast, low-latency access, such as databases and file systems. It is also well-suited for use as a boot volume for EC2 instances, allowing you to store the operating system and application files on a separate, persistent volume.
Here is an example of how to use the AWS SDK for Python to create a new EBS volume and attach it to an EC2 instance:
import boto3
ec2 = boto3.client('ec2')
response = ec2.create_volume(AvailabilityZone='us-east-1a', Size=1, VolumeType='gp2')
volume_id = response['VolumeId']
ec2.attach_volume(Device='/dev/xvdf', InstanceId='i-1234567890abcdefg', VolumeId=volume_id)
Processing
Once you have your data stored in the cloud, you may need to perform various types of processing on it, such as transforming, aggregating, or filtering. AWS provides a range of services that can help you do this efficiently and at scale.
EC2
As mentioned earlier, Amazon EC2 is a web service that provides resizable compute capacity in the cloud. You can launch on EC2 instances, which are virtual machines running in the cloud, and use them to perform a variety of tasks, including data processing.
One of the key advantages of using EC2 for data processing is that you have complete control over the hardware and software resources of the instances. This means you can choose the exact configuration and packages that are optimal for your workload, and scale up or down as needed to meet the changing demands of your application.
Here is an example of how to use the AWS SDK for Python to launch a new EC2 instance and run a simple data processing job on it:
import boto3
ec2 = boto3.client('ec2')
response = ec2.run_instances(
ImageId='ami-12345678',
InstanceType='t2.micro',
MinCount=1,
MaxCount=1,
KeyName='my-key-pair',
SecurityGroups=['my-security-group']
)
instance_id = response['Instances'][0]['InstanceId']
ec2.wait_until_instance_running(InstanceIds=[instance_id])
import paramiko
ssh = paramiko.SSHClient()
ssh.connect(hostname='ec2-12-34-56-78.compute-1.amazonaws.com', username='ec2-user', key_filename='my-key-pair.pem')
stdin, stdout, stderr = ssh.exec_command('python my_data_processing_script.py')
for line in stdout:
print(line.strip())
EMR
Amazon EMR (Elastic MapReduce) is a fully-managed service that makes it easy to process and analyze large data sets using the Hadoop ecosystem and other big data technologies. EMR allows you to create a cluster of EC2 instances that are pre-configured with a range of tools and frameworks, such as Hadoop, Spark, Hive, and Pig, and then run data processing and analytics jobs on the cluster.
EMR is well-suited for a wide range of data processing and analytics tasks, including batch processing, stream processing, machine learning, and SQL queries. It is also highly scalable and can automatically add or remove nodes from the cluster based on the workload.
Here is an example of how to use the AWS SDK for Python to create an EMR cluster and run a Spark job on the cluster:
import boto3
emr = boto3.client('emr')
response = emr.run_job_flow(
Name='My EMR Cluster',
ReleaseLabel='emr-6.0.0',
Instances={
'InstanceGroups': [
{
'Name': 'Master nodes',
'Market': 'ON_DEMAND',
'InstanceRole': 'MASTER',
'InstanceType': 'm5.xlarge',
'InstanceCount': 1
},
{
'Name': 'Worker nodes',
'Market': 'ON_DEMAND',
'InstanceRole': 'CORE',
'InstanceType': 'm5.xlarge',
'InstanceCount': 2
}
],
'Ec2KeyName': 'my-key-pair',
'KeepJobFlowAliveWhenNoSteps': True,
'TerminationProtected': False
},
Applications=[{'Name': 'Spark'}],
Configurations=[
{
'Classification': 'spark-env',
'Configurations': [
{
'Classification': 'export',
'Properties': {
'PYSPARK_PYTHON': '/usr/bin/python3'
}
}
]
}
],
JobFlowRole='EMR_EC2_DefaultRole',
ServiceRole='EMR_DefaultRole',
VisibleToAllUsers=True,
Tags=[
{
'Key': 'project',
'Value': 'data-processing'
}
]
)
cluster_id = response['ClusterId']
emr.wait_until_cluster_running(ClusterId=cluster_id)
emr.add_job_flow_steps(
ClusterId=cluster_id,
Steps=[
{
'Name': 'Spark job',
'ActionOnFailure': 'CONTINUE',
'HadoopJarStep': {
'Jar': 'command-runner.jar',
'Args': [
'spark-submit',
'--deploy-mode', 'cluster',
'--class', 'com.example.MySparkJob',
's3://my-bucket/my-spark-job.jar' ]
}
}
]
)
step_id = response['StepIds'][0] emr.wait_until_step_complete(ClusterId=cluster_id, StepId=step_id)
emr.terminate_job_flows(JobFlowIds=[cluster_id])
In this example, we create an EMR cluster with one master node and two worker nodes, and then run a Spark job on the cluster by adding a Spark step. The Spark job is submitted using the spark-submit script, and the --deploy-mode cluster flag tells Spark to run the job in cluster mode, using the available worker nodes to parallelize the computation.
EMR also provides several other features and capabilities, such as integration with other AWS services, such as S3 and Athena, support for custom AMIs and bootstrap actions, and the ability to run Jupyter notebooks on the cluster.
Analysis
Once you have processed your data, you may want to perform various types of analysis on it, such as querying, visualization, or machine learning. AWS provides a range of services that can help you do this quickly and easily.
Athena
Amazon Athena is a serverless, interactive query service that allows you to analyze data in Amazon S3 using SQL. Athena is particularly useful for ad-hoc querying and exploration of large datasets, as it allows you to run queries on S3 data without having to first load it into a separate data store.
Athena is based on Presto, an open-source SQL query engine, and supports a wide range of data formats, including CSV, JSON, ORC, Parquet, andAVRO. It is also highly performant, with the ability to parallelize queries across thousands of nodes.
Here is an example of how to use the AWS SDK for Python to run a query on an Athena table and print the results:
import boto3
athena = boto3.client('athena')
response = athena.start_query_execution(
QueryString='SELECT * FROM my_table LIMIT 10',
QueryExecutionContext={
'Database': 'my_database'
},
ResultConfiguration={
'OutputLocation': 's3://my-bucket/athena-results/'
}
)
query_execution_id = response['QueryExecutionId']
athena.wait_until_query_complete(QueryExecutionId=query_execution_id)
response = athena.get_query_results(QueryExecutionId=query_execution_id)
columns = response['ResultSet']['ResultSetMetadata']['ColumnInfo']
rows = response['ResultSet']['Rows']
for row in rows:
values = row['Data']
print(','.join([val['VarCharValue'] for val in values]))
QuickSight
Amazon QuickSight is a cloud-based business intelligence (BI) service that allows you to create and publish interactive dashboards and reports. QuickSight integrates with a wide range of data sources, including S3, Athena, Redshift, and RDS, and provides a drag-and-drop interface for building charts and graphs.
QuickSight is a great option for quickly visualizing and exploring your data, as well as for creating dashboards and reports that can be shared with your team or organization.
Here is an example of how to use the AWS SDK for Python to create a new QuickSight dataset from an S3 bucket and build a simple bar chart from the data:
import boto3
quicksight = boto3.client("quicksight")
response = quicksight.create_data_set(
AwsAccountId="123456789012",
DataSetId="my-dataset",
Name="My Dataset",
PhysicalTableMap={

error: cannot format : Cannot parse: 1:51: response = quicksight.get_dashboard_embed_url( AwS AccountId='123456789012', DashboardId='my-dashboard', IdentityType='IAM', ResetDisabled=True ) dashboard_url = response['EmbedUrl'] print(f'Dashboard URL: {dashboard_url}')
Sagemaker
Amazon SageMaker is a fully managed machine learning service that enables developers and data scientists to build, train, and deploy machine learning models quickly. SageMaker removes the heavy lifting from each step of the machine learning process, so developers and data scientists can focus on the interesting parts: designing, training, and fine-tuning models.
SageMaker provides several tools for preparing, processing, and modeling data, including Jupyter notebooks, data preparation and transformation libraries, and algorithms for training models. It also provides integration with popular deep learning frameworks, such as TensorFlow and PyTorch, so you can use the libraries and tools you're already familiar with.
Here's a simple example of how you can use SageMaker to train and deploy a machine learning model using the Python SDK:
First, you'll need to install the SageMaker Python SDK and set up your AWS credentials:
pip install sagemaker
Next, you'll need to create a sagemaker.Session object, which you'll use to interact with SageMaker:
import sagemaker
sagemaker_session = sagemaker.Session()
Next, you'll need to specify the data that you'll use to train your model. You can use the sagemaker.session.upload_data function to upload your data to an Amazon S3 bucket, which SageMaker will use to store the data and model artifacts:
Copy codedata_path = sagemaker_session.upload_data(path='data.csv', key_prefix='data')
Next, you'll need to specify the training script and the entry point for your model. The training script should be a Python script that loads and prepares the data, trains a model, and saves the trained model to a file:
!pygmentize train.py
import argparse
import pandas as pd
from sklearn.ensemble import RandomForestClassifier
if __name__ == '__main__':
parser = argparse.ArgumentParser()
parser.add_argument('--n-estimators', type=int, default=10)
parser.add_argument('--min-samples-leaf', type=int, default=3)
parser.add_argument('--max-depth', type=int, default=None)
parser.add_argument('--output-data-dir', type=str, default=os.environ['SM_OUTPUT_DATA_DIR'])
parser.add_argument('--model-dir', type=str, default=os.environ['SM_MODEL_DIR'])
parser.add_argument('--train', type=str, default=os.environ['SM_CHANNEL_TRAIN'])
args = parser.parse_args()
input_data = pd.read_csv(os.path.join(args.train, "train.csv"), header=None, names=None)
labels = input_data.iloc[:,0]
features = input_data.iloc[:,1:]
model = RandomForestClassifier(n_estimators=
Once you have your training script and data ready, you can use the sagemaker.estimator.Estimator class to specify the training job and launch it. The Estimator class takes several arguments, including the training script, the training instances, and the hyperparameters for the training job:
from sagemaker.sklearn.estimator import SKLearn
sklearn = SKLearn(
entry_point='train.py',
train_instance_type='ml.m4.xlarge',
role='<Your IAM Role>',
sagemaker_session=sagemaker_session,
hyperparameters={
'n-estimators': 10,
'min-samples-leaf': 3,
'max-depth': None
}
)
Next, you can call the fit method of the Estimator object to start the training job:
sklearn.fit({'train': data_path})
Once the training job is complete, you can use the trained model to make predictions. To do this, you'll need to deploy the model to an endpoint using the deploy method of the Estimator object:
predictor = sklearn.deploy(initial_instance_count=1, instance_type='ml.m4.xlarge')
Finally, you can use the predictor object to make predictions on new data. The predictor object has a predict method that takes a NumPy array of input data and returns a NumPy array of predictions:
import numpy as np
data = np.array([[5.1, 3.5, 1.4, 0.2]])
predictions = predictor.predict(data)
print(predictions)
This is just a basic example of how you can use SageMaker to train and deploy a machine learning model. SageMaker provides many other features and tools that you can use to build more complex and powerful models.
