LendingClub runs 400+ microservices that comprise its online marketplace lending platform, the largest in America. Every one of these services has been developed, tested and deployed without drama. How? Our DevOps team uses Neo4j to manage infrastructure and operate the company.
Through our DevOps journey from monolith to microservices, datacenter to cloud, we learned that in order to automate all the things, we needed to have accurate and timely data about what exactly those things were. By loading all infrastructure components — from source code repositories to CI jobs, from bare metal hosts to virtual servers to containers, from load balancers to auto-scaling groups — into Neo4j, we created a single, central hub of information that we could query at any time and that helped us make sense of our complex, interdependent infrastructure components.
Understanding and dynamically mapping the relationships among our infrastructure gave us visibility into components that we previously had no idea were related. It allowed us to answer important questions vital to ensuring our site had four nines of uptime.
We set up monitoring, alerting and reporting that helped us to prevent outages before they happened. We fully automated our datacenter deployments. When the time came to move to the cloud and containers, we fully automated app cluster spin-up and deployments. All these things and more were made possible because of our graph model.
