The last 5 projects completed by myself:1. ClusterBash> Develop customized ssh server and client to compose a mutual trusting cluster.> Provide gRPC API interfaces for other programs to control hosts in the cluster.2. Automated patrol tools> Based on ClusterBash. It can quickly check hundreds of complex inspection items for all nodes in the cluster, and those items include os, storage, network, database, etc. Concurrency performance is good. All checks for about 200 nodes can be completed in 5 minutes.3. Telegraf plugins:> modify original counter plugins to add speed rates to those counters by calculating the difference of interval.> create new plugins to provide developing frameworks in conditions of resource pools, such as querying oracle DBs or running bash scripts.> my source is on https://github.com/ChengWu-NJ/telegraf_plugins.4. Distributed storage based on NVMe over Fabrics> Adopt Infiniband and NVMe over Fabrics to consolidate the resources of multiple storage nodes, and form a resource pool to provide unified management and unified allocation.> Provide gRPC API interfaces to create or delete dynamic volume (block device)> Develop a Kubernetes CSI and a CNI of infiniband to use this distributed storage.5. Distributed state machine> Develop this framework for operation and maintenance activities such as installation, backup, and disaster recovery of various distributed systems.> The basic principle is to split a system into dependent units, and each unit uses a state machine to perform state transitions. The operation of the overall system is completed by the set of state transitions of the contained units.> Use golang reflect technology to achieve a less coding framework. Define the state switching function and operation plan of the unit by means of toml script file.> Support for running multiple operation plans at the same time.Language: bash, golang, c, pythonOS: rhel/centosTechnology: rdma, dm, udev, multipath, docker etc.
