Comparing design approaches for building serverless microservices
Developers often move from single responsibility functions to the Lambda-lith when they architectures demand it, but both approaches have relative trade-offs. It’s possible to have the best of both approaches by dividing your workloads per read and write operations.
Build real-time applications with Amazon EventBridge and AWS AppSync
Directly invoking AWS AppSync GraphQL API targets from EventBridge simplifies and streamlines integration between these two services, ideal for notifying a variety of subscribers of data changes in event-driven workloads. You can also take advantage of other features available from the two services.
Invoking on-premises resources interactively using AWS Step Functions and MQTT
Accessing on-premises resources with workers controlled via Step Functions using MQTT and AWS IoT Core is a secure, reactive, and cost effective way to run on-premises jobs. Consider updating your hybrid workloads from using inefficient polling or schedulers to the reactive approach described in this post.
Consuming private Amazon API Gateway APIs using mutual TLS
This post explores ways to provide mutual TLS authentication for private API Gateway endpoints. A previous post shows how to achieve this using a self-managed NGINX proxy. This post simplifies the architecture by using the native mTLS support now available for Application Load Balancers.
Python 3.12 runtime now available in AWS Lambda
Lambda now supports Python 3.12. This release uses the Amazon Linux 2023 OS, supports Unicode responses, and graceful shutdown for functions with external extensions, and Python 3.12 language features.
Introducing the AWS Integrated Application Test Kit (IATK)
The AWS Integrated Application Test Kit is a software library that provides conveniences to help you write automated tests for your cloud applications. This blog post shows some of the features of the initial Python version of the IATK.
Enhanced Amazon CloudWatch metrics for Amazon EventBridge
This blog shows how to use these new metrics to improve the visibility of event flows in your event-driven applications. It helps you monitor the events more effectively, from invocation until the delivery to the target. This improves observability by proactively alerting on key metrics.
Introducing the Amazon Linux 2023 runtime for AWS Lambda
With this launch, you can now build your Lambda functions using Amazon Linux 2023 as the custom runtime or use it as the base image to run your container-based Lambda functions.
Introducing faster polling scale-up for AWS Lambda functions configured with Amazon SQS
The improved Lambda SQS event source polling scale-up capability enables up to five times faster scale-up performance for spiky event-driven workloads using SQS queues, at no additional cost.
Sending and receiving webhooks on AWS: Innovate with event notifications
Webhooks are a popular method for applications to communicate, and for businesses to collaborate and integrate with customers and partners. This post shows how you can build applications to send and receive webhooks on AWS.
