Clojure on AWS Lambda is like the Reese's Peanut Butter Cup of the functional programming world. Lambda gives you an easy way to run your functions in the cloud without needing to provision or manage any servers. It's also really cheap and extremely scalable. In this short presentation we'll walk through building and deploying a Clojure microservice using only AWS Lambda and API Gateway. We'll also discuss ways that your Lambda functions could support larger applications in an AWS environment.

Bio:

Dan Anolik has been doing a mix of software development and solutions architecture in the Portland area for over 19 years. He has worked as a consultant for building cloud native applications and is a fairly recent convert to Clojure. Away from the keyboard Dan plays mandolin in a bluegrass band and has been a long-time wilderness search and rescue volunteer.

This month we'll have member provided lighting talks. We have two scheduled so far and room for more. Get in touch if you want to do one also.

First we have John Skilbeck talking about converting a traditional Clojure project meant to be run on a server or on docker into a AWS Lambda runtime, while leaving the original project's source code intact. He'll provide a brief background on AWS Lambda and how that works, and then a walkthrough of the project.

Then we'll have JR Heard's talk: An Introduction to Specter

Specter is a library that allows you to elegantly and performantly manipulate Clojure/Script data structures. In this sure-to-be-compelling lightning talk, we'll learn why Specter exists, how to use it, and how to write our own Specter "navigators".

The Portland Serverless Meetup is back! New hosts, new location, same great group.

Interested in speaking at a future event? Message us and let us know! We'd love to have you.

This month we'll have two talks:

Self-healing serverless applications

Serverless applications increasingly involve distributed systems where errors and bottlenecks can have significant downstream impact. This can be compounded by the ephemeral nature of FaaS offerings in which errors can be difficult to diagnose retroactively. In this session we'll discuss instrumentation and "self-healing" architectural patterns that will improve resiliency of your application and drive improved observability and performance.

You get serverless. Your team gets serverless. But does your organization get serverless?

You know a serverless architecture is the right solution for a project, but your VP of Engineering is pushing back. They are probably doing this because it’s not obvious how a serverless architecture will fit into the organization’s existing development, testing, and release processes. Their intuition that new techniques are needed to effectively maintain and extend serverless architectures is spot-on. But they can be convinced serverless is the right approach if you show them successful patterns.

Join us as we kick off OSCON with this fireside chat community event (open to all, no need to be an OSCON attendee!) with Kelsey Hightower and Nate Taggart.

Nate and Kelsey will be exploring the impact, trends, and future of serverless from the perspective of both cloud providers and the developer community. This is an event you won't want to miss!

This month we will have two talks:

"What the Heck is OAuth?"

The OAuth 2.0 authorization framework has become the industry standard in providing secure access to web APIs. OAuth allows users to grant external applications access to their data, such as profile data, photos, and email, without compromising security. However, OAuth can be intimidating when first starting out. In this talk, Aaron Parecki will break down the various OAuth workflows and provide a simplified overview of the framework, highlighting a few typical use cases for web apps, mobile apps and browserless devices.

Aaron Parecki is a developer advocate at Okta, and maintains oauth.net. He's the co-founder of IndieWebCamp, a yearly unconference focusing on data ownership and online identity, and is the editor of the W3C Webmention and Micropub specifications.

Alanna Risse will show us how she built a working 'bananaphone' with google cloud voice.

Alanna Risse is a artist, web developer, and full stack mentor at Thinkful. Her piece “Bananaphone” was included in a group show at PNCA this summer. This interactive piece features a Google AIY Voice/Rasperry Pi Zero encased in an oversized paper maché bananaphone. Her website is http://alannarisse.com

This month Chuck Jewell from Sightbox will be sharing how Sightbox is solving legacy app and database transitions using the strangler pattern and GraphQL.

Legacy app strangulation with GraphQL on AWS AppSync

Database concepts like linearizability and serializability sound abstract, but they can have real-world consequences. Chris Fauna from Fauna DM will give us a look at consistency in the real world, and how flaws can impact your applications. We’ll take a tour of FaunaDB’s globally consistent transaction pipeline and compare it to the alternative approach taken by Google Spanner.

Deterministic Global Database Consistency

Join us for a short demo and discussion on programming Adafruit microcontrollers and an Echo Dot. Ming Rutar two projects she has been working on and would love to hear your suggestions.

If you would like to join the discussion check us out on Zoom https://zoom.us/j/7891236789. If you want to listen, we're also on Facebook Live https://www.facebook.com/KnowledgeMavens/.

Do you want to learn and share your passion in a supportive community? Knowledge Mavens is an ethos of sharing, creativity, and inspiration.

Our Meetup provides an opportunity to "Show and Tell" followed by a feedback and Q&A. You'll have the opportunity to share with our channels such as Meetup, GitHub, YouTube, and Facebook to connect with more passionate people.

The second half of our session we'll collaborate on new topics. The winner wins an award for the most interesting topic and the opportunity to share in an upcoming session.

Safe Lambda Deployments

AWS Lambda and AWS CodeDeploy enable developers to safely deploy new application code to production. In this talk, we will discuss how Saks Fifth Avenue adopted 'safe deployment' practices for AWS Lambda functions. We'll examine traffic shifting, traffic hooks, YAML configuration, and the CodeDeploy API.
