AWS Lambda Reserved Concurrency

Lambda is a wonderful platform. The problems In Learning Lambda Part 9 , I described Lambda’s scaling behavior?—?that The only limit to Lambda’s scaling is the cross-account concurrent execution limit. Could Amazon improve Lambda to aid us in these concerns?

Lambdas, Lambdas Everywhere. Below is the first, for my talk on “Lambdas, Lambdas Everywhere.” Here’s the abstract: Why care about C++0x lambda functions? Note that lambda functions, although futuristic, are not a far-future feature.

A Guide to Reducing Cold Start Frequency


performance serverless aws lambda faas lambda architecture cold startTime is money , especially in the age of the Internet. In fact, users decide within 8 seconds if they're going to continue using your service. Frequent lags can destroy your reputation. If you have a serverless architecture , cold starts can cause these lags.

The Easiest Way to Compute in the Cloud – AWS Lambda

All Things Distributed

Our answer is a new compute service called AWS Lambda. AWS Lambda makes building and delivering applications much easier by giving you a simple interface to upload your Node.js code directly to Lambda, set triggers to run the code (which can come from other AWS services like Amazon S3 or Amazon DynamoDB, to name a couple), and that’s it: you’re ready to go. You can go from code to service in three clicks and then let AWS Lambda take care of the rest.

Serverless at re:Invent 2017

The Symphonia

It’s funny to think that AWS Lambda was announced at re:Invent only 3 years ago?—?the the industry and Lambda platform both have moved forward a long way since. This year’s re:Invent saw a lot of incremental improvements for Lambda and its related services.

aws lambda presentations architecture serverlessHi everyone. It’s been a great, fascinating, and busy 2019 for John and I (Mike) at Symphonia. You’ll probably be able to tell that we haven’t had too much spare time because of the lack of updates around these parts! We’ve made it to a few conferences though around the globe, from California to Hungary, and places in between. Here are some videos of our talks from them.

Amazon announces the Alexa Skills Kit, Enabling Developers to Create New Voice Capabilities

All Things Distributed

The easiest way to build a skill for Alexa is to use AWS Lambda , an innovative compute service that runs a developer’s code in response to triggers and automatically manages the compute resources in the AWS Cloud, so there is no need for a developer to provision or continuously run servers.

Firecracker: lightweight virtualization for serverless applications

The Morning Paper

Firecracker is the virtual machine monitor (VMM) that powers AWS Lambda and AWS Fargate, and has been used in production at AWS since 2018. The first version of AWS Lambda was built using Linux containers.

Expanding the Cloud: Amazon Machine Learning Service, the Amazon Elastic Filesystem and more

All Things Distributed

Amazon Lambda. One of the most exciting technologies we have built lately at AWS is Amazon Lambda. A great example by Valentino in the AWSSummit today was the use of Lambda by Adroll to deliver real-time updates around the word to their DynamoDB instances.

What is Serverless Architecture?


Whether you choose Azure Functions or AWS Lambda, you cannot easily switch to another. Azure Functions don't have this restriction, but on AWS Lambda, functions are not allowed to run for longer than 5 minutes. Amazon: AWS Lambda.

Did you get your re:Invent holiday wish?

The Symphonia

Lambda is 4 years old, and clearly one of AWS’ main paths forward, along with machine learning. Lambda, alone, had a treasure trove of updates: Python 3.7, Ruby, C++, and Rust are now Lambda languages directly supported by AWS. Along with Custom Runtimes comes Lambda Layers?—?artifacts

Formal foundations of serverless computing

The Morning Paper

Lambda operational semantics. One nice thing that SPL gets right here (and that e.g. AWS Lambda / Step Functions get wrong imho!) Whereas on AWS for example, when a lambda gets a bit too big, and you want to evolve it into a step function, far too much has to change.

Transforming Development with AWS

All Things Distributed

When I talk to our customers, I hear time and again how they are taking these transformative principles, and taking them to the next level, by building smaller, more discrete, distributed components using containers and AWS Lambda. We also added C# support for AWS Lambda.

All Things Distributed

An AWS Lambda function is a simpler option that you can use, as it only requires you to code the logic, set it, and forget it. All you need to do is register the AWS Lambda function that needs to be executed in response to a specific data change in the DynamoDB table.
