AWS introduced Lambda Layers at re:invent 2018 as a way to share code and data between functions within and across different accounts. It’s a useful tool and something many AWS customers have been asking for. However, since we already have numerous ways of sharing code, including package managers such as NPM, when should we use Layers instead? In this post, we will look at how Lambda Layers works, the problem it solves and the new challenges it introduces.

Stackery is a tool to deploy complete serverless applications via Amazon Web Services (AWS). Epsagon monitors and tracks your serverless components to increase observability. Here’s how they can not only work together but improve each other. Let’s start with a scenario: it’s late in the day on Thursday, traffic to your site is way up, and you have reports of problems.

We had a blast at this year’s SREcon in Brooklyn, NY. The three-day event included meeting with integration partners and deepening our understanding of website reliability from a DevOps perspective.

With over 48,000 stars on GitHub, more than 75,000 commits, and with major contributors like Google and Red Hat, Kubernetes has rapidly taken over the container ecosystem to become the true leader of container orchestration platforms. Kubernetes offers great features like rolling and rollback of deployments, container health checks, automatic container recovery, container auto-scaling based on metrics, service load balancing, service discovery (great for microservice architectures), and more.

This post demonstrates a *basic* example of how to build a deep learning model with Keras, serve it as REST API with Flask, and deploy it using Docker and Kubernetes. This is NOT a robust, production example. This is a quick guide for anyone out there who has heard about Kubernetes but hasn’t tried it out yet. To that end, I use Google Cloud for every step of this process.

Cognito is AWS’s cloud solution for authentication – if you’re building an app that handles users with passwords, you can use AWS to handle the tricky high-risk security issues related to storing login credentials. No need to go it alone! Pricing is based on your number of monthly active users, and the first 50k users are free. For apps I’ve worked on, we would have been very pleased to grow out of that free tier.

Continuing the trend from last year, in 2019 we see more organizations riding the wave of Serverless and Kubernetes, and many are starting to see tangible results. The widespread adoption of these technologies, however, has only just begun. Below, we examine five trends in serverless that are sure to impact the way organizations develop and deliver software for years to come.

Lumigo VP Product Avishai Shafir rounds up the most interesting talking points from the three-day Serverless Architecture Conference, held in The Hague, Netherlands.

I’m in a position where I converse with our customers and cloud service providers, and I keep track of conversations happening through blogs and social media. I then sift through all this data to identify patterns and trends. Lately, I’ve seen some talk about an architectural pattern that I believe will become prevalent in the near future.
