Welcome to Issue #48 of Off-by-none. Thanks for joining us this week! 👋
Last week, we looked at the new full lifecycle Serverless Framework and heard some additional thoughts about Amazon EventBridge. This week, we take a deep dive into the recently announced Laravel Vapor, and as always, share lots of amazing content from the serverless community.
Before we begin, make sure you fill out the State Of Serverless Community Survey that Serverless, Inc. is running. Always amazing insights from the results.
Okay, there’s a lot of amazing serverless content to get to. Let’s get right to it. 🏎
This past week at Laracon, Taylor Otwell, creator of the Laravel framework for PHP, launched Laravel Vapor. Vapor is a new deployment and management service that lets you run serverless Laravel! Using your existing Laravel projects, you can use Vapor to deploy your application to a combination of Lambda, SQS, S3, and CloudFront. You also have several options around caches and databases, including Aurora Serverless.
This is a very, very big deal for the serverless community. Laravel is extremely popular, has an active community, and boasts tens of thousands of production implementations in the wild. Introducing an entire population of PHP developers to serverless and letting them easily reuse millions of hours of development time, is perhaps one of the most frictionless paths to serverless I’ve ever seen! Plus, Vapor only interfaces with the customer’s AWS account, giving developers complete control to add additional services to extend their applications with other serverless AWS offerings. I’m excited to see what people do with this.
If you’re interested in learning more about the details of Vapor, Taylor Otwell and I had a chat (Serverless Chats – Episode #7) about it. Lots of really great information in here that gets into the nuts and bolts of how it works, and what the future of Laravel and serverless might look like.
New tool from cloud startup Stackery streamlines AWS serverless development
Wow! Stackery has released their CLI as a standalone tool that anyone can use, even without a Stackery account. Debugging and iterating locally is a huge time saver when developing serverless applications. Tying into your cloud resources makes this so much easier. Learn more here.

Simple Two-way Messaging using the Amazon SQS Temporary Queue Client
What sort of black magic is this? Temporary queue clients for Request-Response scenarios using SQS instead of HTTPs? Very interesting, though not sure how long-polling receivers would work with Lambdas just yet.
Serverless Web Scraping With Python, AWS Lambda and Chalice
Danny Aziz lays out a five step plan for using Lambda to pull data from other sites.
Manage databases through custom skills with Amazon Alexa and AWS Systems Manager
“Alexa, drop all my production databases.” As long as that command isn’t supported, I think this is a pretty cool use case.

The power of Lambdas (beyond just resizing images for you). Gary Sieling points out an excellent use case, debugging other services in your account.
Serverless Video Rendering
I’ve seen some examples of this before, but parallelizing video rendering could be very powerful if it is done right.

AWS S3 Event Notifications have “probably once” delivery
Eric Urban coined this phrase to emphasize the “on very rare occasions, events might be lost” issue with S3 notifications. He implements a clever way of dealing with it, though a delivery guarantee would be much better.

Awfully Thorough Guide to Choosing the Best Serverless Solution
I included this post by Ilya Kritsmer two weeks ago, and he has since added Part 1.2, Part 1.3, Part 2.1, and Part 2.2. Excellent content, but I think he should pace himself a bit. 😉
Forms without servers — handling form submissions with Lambda
James Beswick is back with another great post. I’d guess that 99.9% of websites could be static if it wasn’t for that pesky contact form. Serverless to the rescue.

Ruan Bekker proposes a solution for secrets management.
Cloud Irregular: Amazon won’t spin off AWS, and that’s too bad for AWS
Forrest Brazeal has a great post about the pressure software vendors feel to avoid using AWS because of conflicts from potential clients that compete with Amazon.com. According to him, this is resulting in suboptimal technology choices in order to hedge bets against future customers. Seems crazy, but I totally get it.
How Serverless Is Impacting the IT Landscape
Bit of a plug article, but has some interesting statistics about the electricity use of data centers. Serverless provides an interesting solution to this problem versus always-on, dedicated resources.

This is quite amazing. Being able to consolidate metrics from across multiple functions is incredibly powerful. This is perfect for common metrics that span across multiple Lambda functions.
Amazon S3 adds support for percentiles on Amazon CloudWatch Metrics
More good stuff for CloudWatch Metrics. This provides customers with more granularity about their request patterns on S3 and helps them observe and diagnose anomalies in request patterns on S3.

There is a very long list of people that are doing #ServerlessGood and contributing to the Serverless community. These people deserve recognition for their efforts. So each week, I will mention someone whose recent contribution really stood out to me. I love meeting new people, so if you know someone who deserves recognition, please let me know.
This week’s star is Taylor Otwell (@taylorotwell). Taylor is the creator and maintainer of the Laravel framework, and a big supporter of the open source PHP community. Even though Vapor is his first major foray into the serverless world, the impact is massive. The work he’s done over the last year has made it possible for Laravel users to easily switch to a serverless solution on AWS. This has the potential to introduces hundreds of thousands of developers to serverless, and that is a very big deal. Thanks for all your work on Laravel, Taylor. And thank you for building out Vapor so that Laravel users can begin to make the serverless leap! 🙌
This was a banner week for serverless. I really think Vapor is going to be a huge gateway for hundreds of thousands of developers to experience serverless. The bigger this community gets, and the more voices we hear from, means we get more tools, better services from cloud vendors, and more innovation and ideas. I really love watching this community grow and seeing all these new faces learning, adopting, and teaching serverless.
