Step 1: Re-­Host

Usually project led by Ops Team“My application on the Cloud”

“Quick” project, minimal effort level

Step 2: Re-­Platform

Usually project led by IT Team“My application in the Cloud”

Limited effort, avoid undifferentiated heavy lifting

Initial transfer

Continuous replication of data

How do I transfer my data?

AWS DMS

Demo: Data ExtractionAutomated Data Transfer between databases

Using the right tool

Blob storage in Amazon S3

var bucketName = "<BucketName>";var fileName = "<FileName>";var s3Client = new Amazon.S3.AmazonS3Client();

// Write Data to Amazon S3s3Client.PutObject(new Amazon.S3.Model.PutObjectRequest

BucketName = bucketName,Key = fileName,InputStream = fileStream

);

// Read Data from Amazon S3var s3Object = s3Client.GetObject(bucketName, fileName);

Amazon S3

Demo: Using Amazon S3Use Amazon S3 instead of the local database for storing files

Loose Coupling Sets You Free

var queueUrl = "https://sqs.<region>.amazonaws.com/<AcctNum>/<QueueName>";var sqsClient = new Amazon.SQS.AmazonSQSClient();

// Send to Amazon SQSsqsClient.SendMessage(queueUrl, "My Message Data");

// Process Amazon SQSwhile(!exit)

var messages = sqsClient.ReceiveMessage(queueUrl);foreach(var message in messages.Messages)

// Process message then deletesqsClient.DeleteMessage(queueUrl, message.ReceiptHandle);

You want micro-­services*

*Don’t say no, everyone wants micro-­services these days

Microservicesmean

Let’s get back to the definition

The services are small -­ fine-­grained to perform a single function;;

The organization culture should embrace automation of deployment and testing. This eases the burden on management and operations;;

The culture and design principles should embrace failure and faults, similar to anti-­fragile systems;;

Each service is elastic, resilient, composable, minimal, and complete.

https://en.wikipedia.org/wiki/Microservices

Simpler

A Microservice is a stand-­alone service that can be (re)built in no more than two weeks

Sam Newman, Building Microserviceshttp://www.amazon.com/gp/product/1491950358/ref=as_li_qf_sp_asin_il_tl

5 characteristics

It is a Stand-­alone service/application;;

It is quick to (re)write;;

It focuses on one task;;

It is Language-­agnostic;;

It knows that failures exist.
