The Beanstalker open source project now supports Java SE application development and deployment directly to AWS Elastic Beanstalk using the Maven archetype elasticbeanstalk-javase-archetype. With just a few commands in a terminal, you can create and deploy a Java SE application. This blog post provides step-by-step instructions for using this archetype. First, in the terminal, type the mvn archetype:generate command. Use elasticbeanstalk as the filter, choose elasticbeanstalk-javase-archetype […]

In the first part of this blog post, we used the AWS SDK for Java to create a Scala application to write data in Amazon Kinesis Firehose, Dockerized the application, and then tested and verified the application is working. Now we will roll out our Scala application in Amazon EC2 Container Service (ECS) and use […]

The key to developing a highly scalable architecture is to decouple functional parts of an application. In the context of an event-driven architecture, those functional parts are single-purpose event processing components (“microservices”). In this blog post, we will show you how to build a microservice using Scala, Akka, Scalatra, the AWS SDK for Java, and Docker. […]

In an earlier blog post, I discussed how a Maven bill of materials (BOM) module can be used to manage your Maven dependencies on the AWS SDK for Java. In this blog post, I will provide an example of how you can use the Maven BOM in your Gradle projects to manage the dependencies on […]

In this blog post we will discuss why it’s important to protect your application from downstream service failures, offer advice for tuning configuration options in the SDK to fit the needs of your application, and introduce new configuration options that can help you set stricter SLAs on service calls. Service failures are inevitable. Even AWS […]

In parts 1, 2, and 3 of this series, we used the AWS Toolkit for Eclipse to create a Java Lambda function. This function authenticated a user against an Amazon DynamoDB table (representing a directory of users) and then connected to Amazon Cognito to obtain an OpenID token. This token could then be used to […]

Today, I’m excited to announce the Practical DynamoDB Programming in Java demo from AWS re:Invent 2015 is available on github. This project is used to demonstrate how Amazon DynamoDB can be used together with AWS Lambda to perform real-time and batch analysis of domain-specific data. Real-time analysis is performed by using DynamoDB streams as an event source of a Lambda function. Batch […]

There’s a great post on the AWS Security Blog today. Greg Rubin explains How to Protect the Integrity of Your Encrypted Data by Using AWS Key Management Service and EncryptionContext. Greg is a security expert and a developer on AWS Key Management Service. He’s helped us out with encryption and security changes in the AWS […]

In parts 1 and 2 of this blog post, we saw how easy it is to get started on Java development for AWS Lambda, and use a microservices architecture to quickly iterate on an AuthenticateUser call that integrates with Amazon Cognito. We set up the AWS Toolkit for Eclipse, used the wizard to create a […]

In part 1 of this blog post, we showed you how to leverage the AWS Toolkit for Eclipse to quickly develop Java functions for AWS Lambda. We then set up a skeleton project and the structure to handle custom objects sent to your Java function. In part 2 of this blog post, we will implement […]
