Embracing Event-Driven Microservices

A few months ago, Anand discussed the benefits of transitioning from traditional HTTP communication to event-driven microservices. He noted how this transition decoupled our services, forced scalable patterns, and increased our resilience. Here, we’ll detail the lessons we learned when we re-implemented our Cron-esque scheduler service, Khronos.

3 Ways We Improved Our Developer Hiring Process

Developer hiring. For both parties, it’s a stress-inducing and potentially life-changing decision. And yet, they each have around 4 hours to gather enough info to make that decision.

How We Saved 98% on Infrastructure Monitoring Costs

It’s important that we provide users with the best experience. Part of that means that our service is available through hardware failures. And when things do go wrong, we need systems in place to monitor key metrics and send alerts to services and our team. Initially, we chose Datadog as our monitoring solution because it was easy to set up, and it provided integrations to services that we used. Then we started scaling our customers’ infrastructure to keep up with demand and saw our infrastructure go from 5 to 500+ servers. This didn’t jive with Datadog’s per-server cost model, as it increased our bill from $75 to $7,500+ per month. In order for us to move away we needed something that provided auto-discovery of new servers, collected host and container metrics, alerted us on abnormal conditions, and had an easy way to visualize data. We turned to the open-source world and discovered Prometheus, a monitoring solution built by SoundCloud.

New ES6 Features in Node LTS

In this blog post, I’ll walk you through some of the new ES6 additions to Node and how they will change the code you write.

Finding the Root Cause of Elusive Frontend Errors

Frontend applications always have a multitude of user interactions and flows for how a user can get to a particular state. Sometimes these states are not intended and errors happen. Errors can be incredibly difficult to track down, so a reliable process for finding the root cause of an error can save a lot of time and confusion. Our process involves using a few services in conjunction.

How We’re Spinning up Our AWS Infrastructure 80% Faster

After our announcement of general availability, our team started focusing on improving our onboarding flow. A key bottleneck was the time it took for us to spin up infrastructure for each new user. This could take up to ten minutes, delaying their initial exposure to our product. We knew we were facing a common problem: reducing the amount of time that it takes to add resources and servers to your infrastructure.

How to Improve Your User Onboarding Flow

No matter how high your CTRs are on your advertising, it won’t translate into active users without an onboarding flow that helps users quickly understand the value of your product. This is what we’ve been focusing on now that Runnable is generally available. Here’s the approach we’ve been using to help more users “see the light”.
