Welcome to Issue #98 of Off-by-none. I’m glad you could join us!
Last week, we announced a new way to explore serverless architectures, learned how to debug and load test serverless applications, and we finally got “connection pools” from Lambda. This week, we get more CDK patterns to explore, yet another reason to look at BigQuery, and some updated serverless best practices. Plus, we have plenty of great content from the serverless community.
Webinar: Would you like to connect applications like GitLab, Confluent, Zendesk, AWS services together?
You can, using TriggerMesh Bridges which allows you to build intelligent application flows using any service, running in the cloud or on-premises. Join us July 30 to see how easy TriggerMesh makes it connect application flows!
Announcing the FaunaDB Data Manager
The FaunaDB Data Manager (FDM) can assist with a variety of import and export tasks, including copying documents, collections, indexes, functions, and roles from one FaunaDB database, at any particular point in time, to another FaunaDB database, plus a variety of useful data features. It’s still in preview mode, but looks like a useful tool for FaunaDB customers.
Google Cloud announces BigQuery Omni multicloud analytics solution
So this sounds way too good to be true, but if I can actually query my AWS data using BigQuery without worrying about data transfer costs or duplicating data, that’s pretty amazing. This could be a game changer.

I’m launching a new web series called Serverless Spotlight that will “Shine a light on the people who make serverless awesome!” The episodes are 5-10 minutes, and will feature people like you sharing what they are working on in serverless. Commercial, open source, blog post, whatever, we want to hear from you. Be sure to sign up to be a guest.
AWS Serverless Customer Success
Not convinced that serverless is ready for primetime? These customer success stories should help change your mind. AWS recently launched a “Serverless Customer Success” page that highlights a series of case studies that show the positive impact of serverless on companies ranging from startups to enterprises.
How I Built a Serverless AWS Lambda Twitter Bot in NodeJS in a Single Day
Spencer Pollock walks through his journey building a Twitter Bot using AWS Lambda. It’s fun following someone’s thought process like this. I would use Parameter Store for my Twitter credentials instead of storing them in a file that’ll likely get checked into git, but for a quick and dirty first go, it’ll do.
The Cloud Resume Challenge, or How I Learned to Stop Worrying and Love the Cloud
Kudos again to Forrest Brazeal for starting the Cloud Resume Challenge. There are several people writing about their experiences, but I found this one from Antonio Lo Fiego to be incredibly enlightening. He doesn’t seem to agree that “… the latest version [of the] SAM CLI makes serverless development easier for developers.” His well-placed JT GIF perfectly encapsulates the way many people new to serverless feel.
How I built a zero cost serverless scraper
Anshaj Khare explains how he built a Twitter scraper using cloud native GCP tools. This post makes me wonder about the differences in the developer experience between GCP and other clouds.
Convert HTML to Markdown with a serverless function
Michael Vigor outlines a simple use case that I certainly wouldn’t want to set up and maintain a server for. I love little one-off services like these that are easy to build with FaaS, and enable developers to build things quickly without all the red tape.
A rock-paper-scissors app with gesture detection and voice
Who would have thought of serverless Rochambeau? The cloud advocates at Microsoft, that’s who. This uses a bunch of Azure native services (not 100% serverless), but still a pretty interesting application of the technologies.
How We Automatically Create And Delete Environments For Developers
Gavin Cornwell has written before about automation using Step Functions, but in this post he shows how his team creates an environment when feature branches are created, and then deletes the environment when the branch is removed.
CDK Patterns at 20! Let’s Walk Through all 20 Serverless Patterns for AWS
Matt Coulter has done an amazing job on the CDK Patterns site and repository and has consolidated all 20 patterns into a comprehensive blog post. There are so many amazing ideas to explore with this, so make sure you check it out.
AWS Serverless Application Lens — A Summary
Amulya Rattan Bhatia attempts to summarize the Well-Architected Serverless Application Lens whitepaper. It’s a much shorter read and does a good job covering the most important points. If you don’t have time to read the whitepaper, this should at least get you headed in the right direction.
Are Lambda-to-Lambda calls really so bad?
This recent post by Yan Cui started a bit of a debate on Twitter regarding his recommendation to put an API Gateway in between inter-service, synchronous calls that ultimately map to a Lambda function. I’m personally a big fan of using synchronous Lambda-to-Lambda calls using the SDK (when appropriate) to reduce overhead and complexity, but Yan makes a lot of really good points why not to do this. Serverless best practices are constantly evolving, so you’d be wise to follow this debate.
Lambda Execution Leaks: A Practical Guide
Dori Aviram points out the problem when unresolved promises leak into your Node-based Lambda functions. This is probably more common than you think, and can be a massive pain to debug. This post outlines what can cause this issue and some ways to mitigate it.

The Serverless LAMP stack part 3: Replacing the web server
Benjamin Smith and Matthieu Napoli (the creator of Bref) show you how to build serverless PHP applications without needing a web server. Matthieu also explains how the implementation of FastCGI Process Manager inside of Lambda helps makes this possible.
Integrating Amazon EventBridge and Amazon ECS
Jakub Narloch shows you how the new EventBridge to API Gateway target enables new use cases. Even if ECS isn’t your thing, you can use this to route events to webhook consumers, map inter-service communication contracts, and even handle complex integration tests.
Get More Out Of Lambda Authorizers- Use Response Context
Adrin Mukherjee outlines a scenario that uses custom authorizers to pass additional context into your Lambda functions that can be used for calls to downstream services. It’s a powerful pattern, and with the integration into Secrets Manager, you can apply a lot of security best practices, including automatic credential rotation.
Creating low-latency, high-volume APIs with Provisioned Concurrency
Even though James Beswick craps on my Lambda Warmer project (😂 totally kidding, I don’t actually use it anymore), he does a great job explaining how Provisioned Concurrency can ensure predictable start-up times to latency-sensitive Lambda functions. And if your workload really needs this, a 75% reduction in your slowest execution times is a compelling reason to spend the extra money.

This is a nice feature for all you MongoDBers out there. You can now copy a snapshot to another region for the purpose of disaster recovery, security, or to populate a development/test environment.
Amazon Keyspaces now enables you to back up your table data continuously by using point-in-time-recovery (PITR)
And for all your Cassandra(ers), PITR provides you with continuous backups of your Amazon Keyspaces table data to help you protect against accidental writes or deletes. When enabled, it’ll back up your table data automatically with per-second granularity and then you can restore your table data to any second in time in the preceding 35 days. Crazy.
