Cloudrail-Java

Cloudrail-Java is a Java library that allows you to easily integrate multiple cloud services into your Java applications. It provides a unified API to access different cloud services like Amazon Web Services, Google Cloud Platform, and Microsoft Azure, among others.

Features

Cloudrail-Java offers the following key features:

• Unified API: Cloudrail-Java provides a unified API to interact with multiple cloud services. This means that the same code can be used to access different cloud services, which leads to a more streamlined development process.

• Strong security: Cloudrail-Java provides strong security features to ensure that cloud services are accessed securely. The library uses OAuth2 authentication for all cloud services, which ensures that credentials are not passed around in clear text.

• Easy to use: Cloudrail-Java is easy to use and requires minimal configuration. The library supports a wide range of cloud services and simplifies the process of integrating them into your Java applications.

Getting started

To get started with Cloudrail-Java, you should first add the Cloudrail-Java dependency to your Java project by adding the following code snippet to your pom.xml file:

<dependency>
    <groupId>com.cloudrail</groupId>
    <artifactId>cloudrail-si-java</artifactId>
    <version>3.1.1</version>
</dependency>

Next, you need to create a Cloudrail service instance by specifying your cloud service API keys:

import com.cloudrail.si.*;
import com.cloudrail.si.interfaces.*;
import com.cloudrail.si.services.*;

public class CloudrailExample {
    public static void main(String[] args) {
        // Specify your API keys here
        final String awsAccessKeyId = "YOUR_AWS_ACCESS_KEY_ID";
        final String awsSecretAccessKey = "YOUR_AWS_SECRET_ACCESS_KEY";

        // Create a new Cloudrail service instance
        final CloudStorage service = new S3(awsAccessKeyId, awsSecretAccessKey);
    }
}

Once you have created a Cloudrail service instance, you can interact with the associated cloud service as if it were a local file system.

Examples

Here are some examples of how to use Cloudrail-Java to interact with different cloud services:

Amazon S3

// Create a new Cloudrail service instance for Amazon S3
final CloudStorage service = new S3(awsAccessKeyId, awsSecretAccessKey);

// List all objects in an S3 bucket
final List<CloudMetaData> objects = service.getChildren("/my-s3-bucket/");
for (CloudMetaData object : objects) {
    System.out.println("Object: " + object.getName());
}

// Upload a file to S3
final File fileToUpload = new File("/path/to/local/file");
service.upload("/my-s3-bucket/my-object-key", fileToUpload, true);

Google Cloud Storage

// Create a new Cloudrail service instance for Google Cloud Storage
final CloudStorage service = new GCS(clientEmail, privateKey);

// List all objects in a Google Cloud Storage bucket
final List<CloudMetaData> objects = service.getChildren("/my-gcs-bucket/");
for (CloudMetaData object : objects) {
    System.out.println("Object: " + object.getName());
}

// Upload a file to Google Cloud Storage
final File fileToUpload = new File("/path/to/local/file");
service.upload("/my-gcs-bucket/my-object-key", fileToUpload, true);

Microsoft Azure Blob Storage

// Create a new Cloudrail service instance for Microsoft Azure Blob Storage
final CloudStorage service = new AzureBlobStorage(accountName, accountKey);

// List all blobs in an Azure container
final List<CloudMetaData> blobs = service.getChildren("/my-azure-container/");
for (CloudMetaData blob : blobs) {
    System.out.println("Blob: " + blob.getName());
}

// Upload a file to Azure Blob Storage
final File fileToUpload = new File("/path/to/local/file");
service.upload("/my-azure-container/my-blob-name", fileToUpload, true);

Conclusion

Cloudrail-Java is a powerful Java library that simplifies the process of integrating multiple cloud services into your Java applications. With Cloudrail-Java, you can easily interact with different cloud services using a unified API, while ensuring that your credentials are kept secure.
