To create an EC2 instance, use
createEC2Instancefunction which takes as arguments: - ec2: an instance from the Ec2Client class - name: a string variable which represents the EC2 instance name - amiId: a string variable which represents the Amazon Machine Image ID- Return Value:
- The instanceId: unique id that represents the created Instance
- Return Value:
-
To switch the status of EC2 instance from running to stopped or vice-versa, use
switchStatusfunction which takes as arguments: - ec2: an instance from the Ec2Client class - instanceId: a string variable that represents the created Instance unique id
- Step 1: Run the code then get the instance id from the I/O console
- Step 2: Comment the following line inside the main function to avoid the recreation of another EC2 instance:
String instanceId = createEC2Instance(ec2,name, amiId );- Step 3: To test the
swicthStatusfunction, use replace the instanceId with the one copied from step 1
switchStatus(ec2, instanceId);- To create an S3 bucket, use
createBucketfunction which takes as arguments: - s3: an instance from the S3Client class - name: a string variable that represents the s3 bucket name - To upload a file to the S3 bucket, use
uploadFileS3Bucketfunction which takes as arguments: - s3: an instance from the S3Client class - name: a string variable that represents the s3 bucket name - PATH: a harcoded variable inside the code represents the path to the CSV file to be uploaded - To create a message queue (sqs), use
createQueuefunction which takes as arguments: - sqsClient: an instance from the SqsClient class - name: a string variable that represents the sqs name - To send a message and insert it into the sqs, use
sendMessagefunction which takes as arguments: - sqsClient: an instance from the SqsClient class - Sqs name: a string variable that represents the sqs name - PATH: a harcoded variable inside the code represents the path to the CSV file to be uploaded - Bucket name: a string variable that represents the S3 bucket name

- To get messages from SQS, use
getMessagefunction which takes as arguments: - sqsClient: an instance from the SqsClient class - name: a string variable that represents the SQS name- Return Value:
- A list of messages
- Return Value:
- To delete messages from the SQS, use
deletMessagesfunction which takes as arguments: - sqsClient: an instance from the SqsClient class - name: a string variable that represents the SQS name - To get a file from S3 Bucket, use
getFileS3Bucketfunction which takes as arguments: - s3Client: an instance from the S3Client class - name of the S3 Bucket (names.get(0)) - name of the file(names.get(1)) - Note: This function used insidegetSumandminmaxValuefunctions - To get the sum, use
getSumfuntion which takes as paramters: - s3Client: an instance from the S3Client class - name of the S3 Bucket (names.get(0)) - name of the file(names.get(1)) - Result: Shown on the I/O console - To get minimum and maximum values, use
minmaxValuefunction which takes as paramters: - s3Client: an instance from the S3Client class - name of the S3 Bucket (names.get(0)) - name of the file(names.get(1)) - Result: Shown on the I/O console - To delete the bucket content, use
deleteBucketContentfunction which takes as paramters: - s3Client: an instance from the S3Client class - name of the S3 Bucket (names.get(0)) - name of the file(names.get(1)) - Result: Shown on the I/O console - To delete the bucket itself, use
deleteS3Bucketfunction which takes as paramters: - s3Client: an instance from the S3Client class - name of the S3 Bucket (names.get(0))
- run the code after runing the S3Bucket.java
