Serverless apps are growing in popularity, thanks to tools like AWS API Gateway and Lambda, and a growing number of powerful frameworks that simplify development and deployment. Complex applications are still complex, however, and regardless of your platform you’ll still need to think about observability.

Just a quick post highlighting some of the changes made since Apex Up v0.5.0! If you’re unfamiliar with Up, it’s a command-line tool to help you deploy and manage near-infinitely scalable serverless web applications and APIs on AWS. You can deploy as many applications as you need, for the fraction of the price of other providers, with zero operational maintenance or manual scaling efforts.

v0.6.2 is released! Need HTTP endpoint monitoring? The new guide by @wmnnd describes how to set up serverless HTTP(S) monitoring!

I've told about why we started to explore serverless in my previous post. And this one will be about what we did and how it went so far. We used to have 9 servers (i.e., AWS EC2 instances) on multiple availability zones, each running a docker engine and all were interconnected with Rancher.

Throughout this series we have been exploring how to use serverless architectures to our advantage. In this article I will show you: How to create a serverless slack command using Node.js & Up, Best Practices when developing serverless applications, A curated list of serverless resources.

In Part 2: Serverless Scales I briefly touched on how a serverless architecture can have a cost benefit. In this post, I will go over: How to approach and analyze the cost of serverless, Two detailed examples of a cost analysis.

In Part 1: What is Serverless? I talked about how one of the biggest pros to a serverless architecture is how well it scales and how high availability is baked in. In this post I’ll go over: How a traditional highly available scalable architecture works, How a scalable serverless architecture works, How you can benefit from a serverless architecture.

In this post we’ll answer the following questions: What is serverless architecture? (and what it’s not), What are the pros & cons of serverless?

Function as a service (FaaS) products like AWS Lambda, Azure Functions, and Google Cloud Functions have instigated a paradigm shift in the way Ops teams provision and manage their organization's infrastructure. With everyday administrative tasks like provisioning, patching, maintaining compliance, and configuring operating systems all being abstracted away, your Ops team only has one task to work on - writing world-class code.

This small release introduces custom stages, stage-level configuration overrides, instant rollbacks and a few other refinements for Up the serverless deployment tool.
