MegazoneCloud and Datadog held Datadog Game Day on the 15th at Red Button Culture Stage in Seoul's Gangnam district, bringing together 56 IT engineers in 17 teams for a live incident response challenge. Participants from development, platform, infrastructure, security and site reliability engineering roles investigated cascading payment delays, error spikes and external attacks in a mock banking service processing millions of transactions. Coinone engineers on team Raichu took first place by resolving the most incidents in the shortest time. The event was designed to demonstrate observability, or the correlated analysis of infrastructure, applications, logs and security through one platform. MegazoneCloud was the first company among Datadog's Asia-Pacific and Japan partners to sign a Strategic Collaboration Agreement.
