Configuring the Parallelization Factor from the AWS Lambda console.

New AWS Lambda scaling controls for Kinesis and DynamoDB event sources

AWS Lambda is introducing a new scaling parameter for Amazon Kinesis Data Streams and Amazon DynamoDB Streams event sources. Parallelization Factor can be set to increase concurrent Lambda invocations for each shard, which by default is 1. This allows for faster stream processing without the need to over-scale the number of shards, while still guaranteeing […]

Migrate IBM MQ to Amazon MQ Step 3

Migrating from IBM MQ to Amazon MQ using a phased approach

This post is contributed by Mithun Mallick, Solutions Architect and Christian Mueller, Solutions Architect Message-oriented middleware (MOM), or message brokers, are the backbone that integrates business critical applications in many industries. MOMs are used to integrate systems like inventory management, payment systems, and CRM systems. They are also used to orchestrate order-processing workflows across multiple systems, […]

Application integration patterns for microservices: Fan-out strategies

This post is courtesy of Dirk Fröhner, Sr. Solutions Architect The first blog in this series introduced asynchronous messaging for building loosely coupled systems that can scale, operate, and evolve individually. It considered messaging as a communications model for microservices architectures. This post covers concrete architectural considerations, focusing on the messaging architecture. Part 3 covers running […]

End User Client accessing a service using an API

Understanding asynchronous messaging for microservices

This post is courtesy of Dirk Fröhner, Sr. Solutions Architect One of the implications of applying the microservices architectural style is that much communication between components happens over the network. After all, your microservices landscape is a distributed system. To achieve the promises of microservices, such as being able to individually scale, operate, and evolve each service, this […]

SQS FIFO example #2

New for AWS Lambda – SQS FIFO as an event source

AWS Lambda first announced support for Amazon SQS standard queues as an event source in April 2018. This allows builders to develop serverless applications using queues to directly invoke Lambda functions. Today, we have expanded this feature to include SQS FIFO queues. This makes it easier to create serverless applications using queues where the order […]

Automating Zendesk With Amazon EventBridge and AWS Step Functions

In July 2019, AWS launched Amazon EventBridge, a serverless event bus that offers third-party software as a service (SaaS) integration capabilities. This service allows applications and AWS services to integrate with each other in near-real time via an event bus. Amazon EventBridge launched with a number of partner integrations, to enable you to quickly connect […]

Dead Letter Queue - DLQ SNS use case with architecture diagram

Designing durable serverless apps with DLQs for Amazon SNS, Amazon SQS, AWS Lambda

This post is courtesy of Otavio Ferreira, Sr Manager, SNS. In a postal system, a dead-letter office is a facility for processing undeliverable mail. In pub/sub messaging, a dead-letter queue (DLQ) is a queue to which messages published to a topic can be sent, in case those messages cannot be delivered to a subscribed endpoint. […]
