Amazon Simple Storage Service (S3), a storage service for the Internet is designed to make web scale computing easier for developers. It offers a simple web-service interface that can be used to store and retrieve data, anytime & anywhere.
Why use S3?
- The most important thing about S3 is its reliability. According to Amazon’s SLA, it guarantees 99.9% uptime
- S3 is fast as compared to other storage services
- Being economical and trustworthy, it is extensively used by developers
- S3 is based on a very simple model ‘Pay Per Usage‘ i.e, you only pay for the usage
- Highly scalable, it secures a solution for backing up and archiving your critical data
- You can also host your static website on S3 with highly available(HA) hosting solution that scales automatically as per the traffic.
In this post, I will walk you through a very simple process of integrating S3 in your application.
How S3 works?
Creating Amazon S3 Bucket
Before you start integrating S3, you need to create an S3 Bucket. Every object in Amazon S3 is stored in a bucket.
To create a bucket:
- Open the Amazon S3 Console
- On the Amazon S3 console, click Create Bucket
- Enter a bucket name in the Bucket Name field
- In the Region box, select a region
- If you want to setup-logging, then click on ‘Set Up Logging‘, Else, go to ‘Create‘ to create the bucket
- When Amazon S3 successfully creates your bucket, the console displays the properties of your empty bucket
Now, you have successfully created a Bucket. You can also manage the permissions on Bucket from the properties tab, available on console.
Integrating S3 in your Application using Amazon S3 SDKs.
Using JAVA SDK:
import com.amazonaws.auth.BasicAWSCredentials; import com.amazonaws.services.elastictranscoder.model.Permission; import com.amazonaws.services.s3.AmazonS3; import com.amazonaws.services.s3.AmazonS3Client; import com.amazonaws.services.s3.model.AccessControlList; import com.amazonaws.services.s3.model.GroupGrantee; import com.amazonaws.services.s3.model.ObjectMetadata; import com.amazonaws.services.s3.model.PutObjectRequest; import java.io.File; // Instantiate the S3 client with your AWS credentials AmazonS3 s3 = new AmazonS3Client(new BasicAWSCredentials( "Aws_Access_Key", "Aws_Secret_Key")); // If you want to create bucket // bucketName: name of the bucket s3.createBucket("bucketName"); // bucketName: Amazon Bucket Name // key: The file location that you want to create for your file. // e.g, key = "user/appName/myapp.zip" // File_To_Save: The location of your file. PutObjectRequest objectFile = new PutObjectRequest( "bucketName", "key", "File_To_Save"); // Set Access Control List AccessControlList acl = new AccessControlList(); acl.grantPermission(GroupGrantee.AllUsers, com.amazonaws.services.s3.model.Permission.Read); objectFile.setAccessControlList(acl); // push file to s3 s3.putObject(objectFile);
Using PHP SDK:
// include the Include the SDK using the Composer autoloader require 'vendor/autoload.php'; use Aws\S3\S3Client; // Instantiate the S3 client with your AWS credentials $s3Client = S3Client::factory(array( 'key' => 'Aws_Access_Key', 'secret' => 'Aws_Secret_Key', )); // If you want to create bucket // bucketName: name of the bucket $s3Client->createBucket(array( 'Bucket' => 'bucketName' )); // push file to s3 // bucketName : Amazon Bucket Name // key: The file location that you want to create for your file. // e.g, key = "user/appName/myapp.zip" // File_To_Save: The location of your file. $client->putObject(array( 'Bucket' => 'bucketName', 'Key' => 'key', 'SourceFile' => 'File_To_Save', 'ACL' => 'public-read' ));
Using RUBY SDK
require 'rubygems' require 'aws-sdk' # Instantiate the S3 client with your AWS credentials s3 = AWS::S3.new( :access_key_id => 'Aws_Access_Key', :secret_access_key => 'Aws_Secret_Key') # If you want to create bucket # bucketName: name of the bucket bucket = s3.buckets.create('bucketName', :acl => :public_read) # push file to s3 # bucketName: Amazon Bucket Name # key: The file location that you want to create for your file. # e.g, key = "user/appName/myapp.zip" # File_To_Save: The location of your file. obj = bucket.objects['key'] obj.write(:file => file_name) puts obj.public_url
