Building on our previous posts regarding messaging patterns and queue-based processing, we now explore stream-based processing and how it helps you achieve low-latency, near real-time data processing in your applications. AWS offers two managed services for streaming, Amazon Kinesis and Amazon Managed Streaming for Apache Kafka (Amazon MSK). What is streaming data? At AWS, we define streaming data as data that is emitted at high volume in a continuous, incremental manner with the goal of low-latency processing. Whereas traditional batch-oriented business intelligence would offer insights in retrospect after months, days, or hours have passed, stream-based processing can offer actionable insights in real time. Stream-based processingRead More →

We hope you’ve enjoyed reading our posts on best practices for your serverless applications. The posts in the following series will focus on best practices when introducing messaging patterns into your applications. Let’s review some core messaging concepts and see how they can be used to address challenges when designing modern cloud architectures. Introduction Applications can communicate information with each other using messages, a mechanism for packaging a data payload and associated metadata. The application that sends a message is called the producer and the application that receives the message is called the consumer. Producers and consumers exchange messages using a variety of transportation channels, for example point-to-point requests, messageRead More →

In our first post, we talked about general design patterns to enable massive scale with serverless applications. In this post, we’ll review the different ways you can invoke Lambda functions and what you should be aware of with each invocation model. Synchronous Invokes Synchronous invocations are the most straight forward way to invoke your Lambda functions. In this model, your functions execute immediately when you perform the Lambda Invoke API call. This can be accomplished through a variety of options, including using the CLI or any of the supported SDKs. Here is an example of a synchronous invoke using the CLI: aws lambda invoke —function-name MyLambdaFunction —invocation-type RequestResponseRead More →

Serverless is one of the hottest design patterns in the cloud today, allowing you to focus on building and innovating, rather than worrying about the heavy lifting of server and OS operations. In this series of posts, we’ll discuss topics that you should consider when designing your serverless architectures. First, we’ll look at architectural patterns designed to achieve massive scale with serverless. Scaling Considerations In general, developers in a “serverful” world need to be worried about how many total requests can be served throughout the day, week, or month, and how quickly their system can scale. As you move into the serverless world, the most important questionRead More →

A key component of enterprise multi-account environments is logging. Centralized logging provides a single point of access to all salient logs generated across accounts and regions, and is critical for auditing, security and compliance. While some customers use the built-in ability to push Amazon CloudWatch Logs directly into Amazon Elasticsearch Service for analysis, others would prefer to move all logs into a centralized Amazon Simple Storage Service (Amazon S3) bucket location for access by several custom and third-party tools. In this blog post, I will show you how to forward existing and any new CloudWatch Logs log groups created in the future to a cross-accountRead More →
