Injection Attacks: Protecting Your Serverless Functions
Security is Less of a Problem with Serverless but Still Critical While trying to verify the claims made on a somewhat facile rundown of serverless security threats, I ran across Jeremy Daly’s excellent writeup of a single vulnerability type in serverless, itself inspired by a fantastic talk from Ory Segal on vulnerabilities in serverless apps...

Lambda@Edge: Why Less is More
Lambda@Edge is a compute service that allows you to write JavaScript code that executes in any of the 150+ AWS edge locations making up the Amazon CloudFront content delivery network (CDN) service. In this post, I’ll provide some background on CDN technologies. I will also build out an application stack that serves country-specific content de...

PHP on Lambda? Layers Makes it Possible!
AWS’s announcement of Lambda Layers means big things for those of us using serverless in production. The creation of set components that can be included with any number of Lambdas means you no longer have to zip up your application code and all its dependencies each time you deploy a serverless stack. This allows you to include dependencies th...

GitHub Actions: Automating Serverless Deployments
The whole internet is abuzz over GitHub Actions, if by ‘whole internet’ you mean ‘the part of the internet that is obsessed with serverless ops’ and by ‘abuzz’ you mean ‘aware of‘. But Actions are a bit surprising! GitHub is a company that has famously focused on doing a single thing extremely well. As the ranks of developer-tooling SaaS comp...

The Case for Minimalist Infrastructure
If your company could grow its engineering organization by 40% without increasing costs, would they do it? If your DevOps team could ship more code and features with fewer people, would they want to? Hopefully, the answer to both of these questions is ‘yes’. At Stackery, we believe in helping people create the most minimal application infrastr...

Five Ways Serverless Changes DevOps
I spent last week at DevOps Enterprise Summit in Las Vegas where I had the opportunity to talk with many people from the world’s largest companies about DevOps, serverless, and the ways they are delivering software faster with better stability. We were encouraged to hear of teams using serverless from cron jobs to core bets on accelerating dig...

The '8 Fallacies of Distributed Computing' Aren't Fallacies Anymore
In the mid 90’s, centralized ‘mainframe’ systems were in direct competition with microcomputing for dominance of the technology marketplace and developers’ time. Peter Deutsch, a Sun Microsystems engineer who was a ‘thought leader’ before we had the term, wrote seven fallacies that many developers assumed about distributed computing, to which ...

Disaster Recovery in a Serverless World - Part 3
This is part three of a multi-part blog series. In the first post we covered Disaster Recovery planning when building serverless applications and in the second post we covered the systems engineering needed for an automated solution in the AWS cloud. In this post, we’ll discuss the end-to-end Disaster Recovery exercise we performed to validate...
