 Hello, we are platform teams in LINE. We are happy to show our open infrastructure-related activity here. First of all, LINE's have messaging services, payments, travel, delivery, games, and so on. These services are built on top of our open infrastructure. This is the number of LINE's open infrastructure. LINE has 180 million monthly active users all over the world. And to accommodate the workload for these users, we have 2,400 hypervisors across four regions. 67,000 virtual machines are running separately from virtual machine. We also have 50,000 bare metal servers. We also have 350 Kubernetes clusters, and a month of Kubernetes cluster nodes is 54,000 nodes, which run on our open infrastructure. And our self storage is 17 petabytes across three regions. Our open infrastructure is quite huge. So we basically feedback problems and its solutions we hit in large scale deployment. This feedback is varied from code level to knowledge level. And also, we started Oslo Metrics project in OpenStack Oslo community, which is really useful to visualize OpenStack internal workload. Thank you.
