The
Site Reliability Engineering
team, or
SRE
for short, is the team responsible for developing and maintaining Wikimedia's production infrastructure. Previously known as Technical Operations, they are in charge of making sure all Wikimedia's sites and services used by the public (including MediaWiki and all associated services) run reliably, securely, and with high performance.

The team's structure
Collaboration Services
We are responsible for building and maintaining the infrastructure aspects of the source code management, CI and CD, task and ticket management systems as well as hosting non-Mediawiki websites and other collaboration services.
Data Center Operations
The Data Center Operations team is responsible for all of Wikimedia’s data center deployments and logistics as well as maintaining our presence in locations across the world. They perform on-site work and maintain the full 5-year life cycle (specs, purchasing, physical install, break/fix and decommissioning) for all hardware.

Infrastructure Foundations
The team focuses on building and maintaining our base platform (“metal cloud”) that forms the foundations upon which nearly everything else in our infrastructure builds upon. On top of our bare metal deployments, their responsibilities include (but are not limited to) configuration management systems, infrastructure automation, orchestration tooling, infrastructure security and network operations.

Observability
The Observability team, or "o11y" for short, works across SRE and Technology to provide teams with diagnostic tools, platforms, and insights into how systems and services perform. It leverages technologies such as Grafana, Kibana/Logstash, OpenSearch, Prometheus, AlertManager and more.

Traffic
The Traffic team is responsible for the critical first layer of high-traffic infrastructure which now spans much of the globe, including our TLS termination and caching layers (ATS, Varnish), load balancing, DNS and our own network.

Data Persistence
The Data Persistence team focuses on Wikimedia’s persistent data storage and retrieval systems, including (No)SQL databases, (distributed) object storage, file storage and backup systems.

Service Operations
The Service Operations team takes care of public and “user-visible” services in close collaboration with both the Technology and Product teams. This includes our MediaWiki platform, the SOA service infrastructure based on Kubernetes, as well as community and developer-facing services like Gitlab, Gerrit, Phabricator and VRTS.
