In an attempt to use Go in the context of AWS, I wanted to see how Go would work with AWS Lambda. I decided to create a small project where the function would take an image and convert it to an ASCII art. Using Go for serverless functions Using Go for serverless functions makes a lot of sense. Speed of execution keeps the costs down and delivers the results quickly. When you are getting charged by the amount of resources you consume and the time it takes to complete your function, using a tec...| Evgenii Pendragon
Like many companies that use the cloud, Wealthfront uses AWS Lambda. And while our lambdas look pristine in the web console and perform their highly specific duties well, there’s quite a bit that happens before our lambdas get to that state–I’m referring to CI/CD. However, depending on the given lambda, the processes to deploy its... Read more| Engineering Blog - Wealthfront

Serverless computing has emerged as a transformative approach to deploying and managing applications. The theory is that by abstracting away the underlying infrastructure, developers can focus solely on writing code. While the benefits are clear—scal...| Java, Debugging, DevOps & Open Source

I thought minimizing Lambda function code was a best practice for Lambda optimization - it's even recommended by AWS in a not-so-old blog post. Turns out, I was wrong.| Better Dev

With some creativity, we can use Lambda Response Streaming to dynamically show status updates, like the progress of long-running processes. And with proper TypeScript types and generator functions, we can write clean, dynamic content streaming Lambda with composable payload enrichers that will impress your work colleagues (if they are into this stuff).| Better Dev
Lambda Response Streaming allows sending incremental responses, but those response chunks can arrive long after you write them. They are buffered in a rather unexpected way, delaying all messages you stream. But there is a workaround to force the stream to flush.| Better Dev
I recently created a CDK library provisioning a CI/CD pipeline for serverless apps on AWS. Having finished the "regular" JS library, it took me a day to convert it to a "proper" CDK Construct library. Not long, and I learned a lot. Here are my thoughts and tips.| Better Dev
There are two reasons to optimize AWS Lambda functions performance. First is money – you pay for the Lambda execution duration. The quicker you do the job, the less you pay. The second is latency – the quicker you do the job, the shorter your client waits for the result. It's a known fact that the decrease of latency improves sales, user engagement, and client satisfaction – so we could argue it's also the money, in the end.| Better Dev
The new version of AWS SDK for JavaScript / TypeScript / Node.js came with a few significant improvements. But does "General Availability" mean "ready for the production"? How to use it? And how to unit test our code using it? Let's take a look at it.| Better Dev
Logging in AWS Lambda functions is simple. You just print the message, and it's sent to the CloudWatch Logs. And everything is fine until you get a surprisingly big bill for the CloudWatch usage, or you need to actually debug some live system. Here are my tips for logging in AWS Lambda, based on my experience with real-live, big-scale functions running on production.| Better Dev

Originally posted at: https://engineering.thetrainline.com/ At Trainline we use AWS Lambda 1 in conjunction with API Gateway 2 for some of our microservices. Different teams use different languages, but in the Data Engineering team we use Clojure 3 - which is a JVM based functional programming language. Here we share some of the experiences we’ve had developing and deploying REST based APIs using JVM based Lambdas. Although we normally use Clojure, in this blog post we will present a Java b...| Bits and pieces
I’ve always stressed that it should never be Kubernetes or Serverless, but rather: What is the right tool for the job. Both technologies are great and both technologies carry their own baggage.
