As we mentioned in an earlier blog, you can now enable the automatic generation of performance metrics when using the AWS SDK for Java, and have them automatically uploaded to Amazon CloudWatch for monitoring purposes. Sometimes, however, you may want to generate more fine-grained metrics, such as per-host and per-JVM metrics, that are not enabled […]

We’re always looking for new ways to improve the tools our team builds, like the AWS SDK for Java and the AWS Toolkit for Eclipse. Sometimes those improvements come as brand new functionality, such as Amazon CloudWatch Metrics for the AWS SDK for Java, and sometimes they’re small tweaks to make the tools faster or […]

Introduction Your Amazon Web Services account is (we hope!) pretty important to you. Whether you’re running mission-critical applications that need to be protected from malicious interlopers, or you simply want to ensure that only the people you specify can bill resources to your AWS account, it is vital that you keep your account and its […]

Ever thought about generating metrics that measure your application’s performance on accessing AWS, and then having those metrics uploaded to Amazon CloudWatch for visualization or monitoring purposes ? How about generating performance metrics of your JVM’s when used against AWS ? Wouldn’t it be nice to capture and visualize metrics related to the runtime environment […]

We’re back in Seattle after spending last week in Las Vegas at AWS re:Invent 2013! It was great to meet so many Java developers building applications on AWS. We heard lots of excellent feature requests for all the different tools and projects our team works on, and we’re excited to get started building them! The […]

Today, at AWS re:Invent 2013, I’m talking about some of the high-level APIs for Amazon S3 and Amazon DynamoDB, but there are a whole lot more high-level APIs in the SDK that I won’t have time to demo. These high-level APIs are all aimed at specific common tasks that developers face, and each one can […]

Today, we have a guest post by Chris Barclay from the AWS OpsWorks team. We are pleased to announce that AWS OpsWorks now supports Java applications. AWS OpsWorks is an application management service that makes it easy to model and manage your entire application. You can start from templates for common technologies, or build your […]

Conditional constraints are a powerful feature in the Amazon DynamoDB API. Until recently, there was little support for them in the Amazon DynamoDB Mapper. You could specify a version attribute for your mapped objects, and the mapper would automatically apply conditional constraints to give you optimistic locking, but you couldn’t explicitly specify your own custom […]

Do you or your company have important data that you need to archive? Have you explored Amazon Glacier yet? Amazon Glacier is an extremely low-cost storage service that provides secure and durable storage for data archiving and backup. Just like with other AWS offerings, you pay only for what you use. You don’t have to […]

The high-level save API of DynamoDBMapper provides a convenient way of persisting items in an Amazon DynamoDB table. The underlying implementation uses either a PutItem request to create a new item or an UpdateItem request to edit the existing item. In order to exercise finer control over the low-level service requests, you can use a […]
