Strategies for Working in Uncertain Systems

My name is Brian "Bizaym" Teschke. I'm a software engineer on a central technology team at Riot Games called Developer Connections and we’ve seen all kinds of system instability issues. My team is responsible for solving common problems across game teams so they can just focus on making awesome games. We often have to write programs that interface with several APIs and libraries - both internal and external - each with their own quirks and inconsistencies. This has allowed us to see patterns of both issues and resolutions, which I’m looking forward to outlining for you in this post.

Improving the Developer Experience for Operating Services

Hello! I’m James “WxWatch” Glenn and I’m a software engineer on the Riot Developer Experience: Operability (RDX:OP) team. My team focuses on providing tools for Riot engineers and operations teams that help them better understand the state of their live services across the globe. Some of these tools include Riot’s service metrics, logging, and alerting pipelines.

Keeping Legacy Software Alive: A Case Study

Hi all, Brian "Penrif" Bossé here with a fresh batch of gory, nerdy details surrounding an outage for League. Today we'll be going through why the EU West shard was out to lunch for just over five hours on January 22, 2021. We don't always write these things up - they take time to do and the reasons for outages aren't always that interesting - but this one was particularly painful as it was quite long and on the heels of some other, unrelated outages so figured it'd be worth a dive.

Scalability and Load Testing for VALORANT

When VALORANT was still early in development, we had high hopes that in the future we’d launch with high initial popularity. From the beginning, we prioritized scalability to make sure we could support the number of players we were hoping for. Once VALORANT entered full production, we began working in earnest on a load test framework to prove out our tech. After many months of work, we successfully ran a load test of two million simulated players against one of our test shards, giving us the confidence we needed for a smooth launch. This article explains how we load tested our platform, and how we tackled the scaling challenges we encountered along the way.

Leveraging Golang for Game Development and Operations

Hi, my name is Aaron Torres and I’m an engineering manager for the Riot Developer Experience team. We accelerate how game teams across Riot develop, deploy, and operate their backend microservices at scale - globally. I’ve been at the company for a little over 3 years and I’ve been writing Go code that entire time. In this article, we’ll be specifically looking at how a few different teams use Go. I’ll be tagging in two technologists - Chad Wyszynski from RDX Operability and Justin O’Brien from VALORANT - to discuss how they use Go for their projects.

Technology Interns in 2020: League of Legends, TFT, & VALORANT

The Riot internship program helps technical players drive their professional growth by embedding them on tech teams and having them contribute to impactful, exciting technology projects. Last year we published an article by some of our interns, giving readers a glimpse at the projects technical interns get to work on. We’re doing a follow-up this year, but with additional sections to reflect our new games. 

There were so many interns excited to contribute to this article that this year we’ll be doing a 2-part series. Intern stories are sorted into categories - the first post (this one) includes all blurbs for League of Legends, TFT, & VALORANTand the second post focuses on General Game Tech & Tooling/Infrastructure.
