KubeCon + CloudNative North America 2022

As more and more online applications and data migrate to the cloud, cloud-native, low-latency distributed storage systems have played an important role in the growth of these companies. TiKV is one such storage system that has been used by hundreds of companies for their mission-critical systems. Although the infrastructure on the cloud has the advantages of elasticity and pay-as-you-go, all resources on the cloud are paid for, including computing resources, storage resources, gateway routing, and cross-AZ traffic. So when building a system on the cloud, you need to consider a variety of things that make the system cost-effective. First, I will briefly introduce some cloud infrastructure and its typical characteristics, local disk and cloud disk, layered elastic distributed file system, several types of computing resources, etc. Next, I will introduce how TiKV reduces data storage space, reduces write amplification, and reduces the amount of data transfer fee across availability zones, etc. Finally, we look forward to several potential ways that TiKV can improve cost performance on the cloud. I hope that some practices on cost-effective optimization in TiKV can give you some reference and inspiration.
