Delivering messages at the scale of the World Cup
Posted on June 29, 2023, Level intermediate Resource Length medium
Events like the World Cup bring together a huge number of fans like Alex all over the world. The biggest challenge in maintaining such a service is scale. The type of traffic for such events can be extremely spiky. A very steady traffic volume can suddenly spike when Mbappe scores the goal that ties the game. Suddenly, FCM needs to notify 250M users about this event. By Michelangelo Mecozzi.

NGINX tutorial: How to use OpenTelemetry tracing to understand your microservices
Posted on April 9, 2023, Level beginner Resource Length long
A microservices architecture comes with many benefits, including increased team autonomy and increased flexibility in scaling and deployment. On the downside, the more services in a system (and a microservices app can have dozens or even hundreds), the more difficult it becomes to maintain a clear picture of the overall operation of the system.Observability tooling gives us the power to build that picture across numerous services and supporting infrastructure.

Reducing Go execution tracer overhead with frame pointer unwinding
Posted on February 1, 2023, Level intermediate Resource Length medium
The Go Execution Tracer (aka runtime/trace) was designed to achieve low enough overhead to be usable on "a server in production serving live traffic". This is achieved by writing events into per-P buffers, using RDTSC for timestamps, and encoding into a relatively efficient binary format. By Felix Geisendörfer.

Micro frontends for Java microservices
Posted on January 31, 2023, Level intermediate Resource Length medium
Microservices have been quite popular in the Java ecosystem ever since Spring Boot and Spring Cloud made them easy to build and deploy. Things have gotten even easier in recent years with the proliferation of new Java frameworks built specifically for microservices: MicroProfile, Micronaut, Quarkus, and Helidon. By Matt Raible.

Securing Lambda function URLs using Amazon Cognito, Amazon CloudFront and AWS WAF
Posted on December 31, 2022, Level intermediate Resource Length medium
Lambda function URLs is a dedicated HTTPs endpoint for a AWS Lambda function. You can configure a function URL to have two methods of authentication: IAM and NONE. IAM authentication means that you are restricting access to the function URL (and in-turn access to invoke the Lambda function) to certain AWS principals (such as roles or users). Authentication type of NONE means that the Lambda function URL has no authentication and is open for anyone to invoke the function. By Marcia Villalba.
