With the rapid development of the Internet and the support of national policies, China's cloud computing industry is developing rapidly, and cloud computing talents have become scarce high-paid talents. As we all know, cloud computing and open source are in love with each other. With the help of the open source community, cloud computing technology quickly occupies the market, but what are the commonly used open source cloud computing tools in 2020?

1 、 Kubernetes

Kuberentes has become one of the most popular open source projects in the past two years. I believe that Kuberentes will have a stronger momentum in the future. It has a large number of extension tools, and its advantages are as follows:

1) Enterprise deployment can be better supported through role-based access control.

2) transfer Kuberentes from a single-user operating system to Unix

3) support running stateful applications in Kubernetes-managed containers and containers.

In addition to the Kuberentes Container Scheduler, CNCF (Cloud Native Foundation) provides a wide range of compatible tools for operating and delivering modern distributed systems, creating functions that can be extended to thousands of self-repairing multi-tenant nodes while enabling operational differences.

2 、 Fluentd

Fluentd is a free and completely open source log management tool that simplifies log collection, processing, and storage without having to write special log processing scripts in maintenance. The performance of Fluentd has been proven in various fields: the largest users currently collect logs from 5000 + servers, the amount of 5TB data per day, and process 50000 messages per second during peak hours.

3 、 Prometheus

Prometheus (Prom), formerly known as SoundCloud's alarm toolkit, has evolved into an independent open source monitoring system. It is a metric monitoring system designed to provide a cloud-local approach to monitoring services. Main features: 1) multi-dimensional data model; 2) time series data by metric name and key-value pair to distinguish, all metrics can be set arbitrary multi-dimensional label; 3) data model is arbitrary, do not need to be deliberately set to dot-separated strings, etc.

4 、 Linkerd

Linkerd is an open source network agent designed to be deployed as a service grid: a dedicated layer for managing, controlling, and monitoring service-to-service communication within an application. By providing a unified, unified instrument and control layer for services, Linkerd free service owners choose the language that best suits their services. By separating communication mechanisms from application code, Linkerd allows you to view and control these mechanisms without changing the application itself.

5 、 CoreDNS

The predecessor of CoreDNS is SkyDNS, and its main purpose is to build a fast and flexible DNS server so that users can access and use data in DNS in different ways. It is designed as a server plug-in for Caddy network services. Each feature of CoreDNS can be implemented as pluggable middleware, such as logging, file-based DNS, and a variety of back-end technologies, and multiple plug-ins can be spliced to create customized pipes. CoreDNS has been extended to access service data directly by Kubernetes and provide it to users in the form of KubeDNS.

Of course, in addition to the above tools, the more commonly used open source cloud computing tools in 2020 include Containerd, gRPC, OpenTracing and so on. Proficiency in a variety of open source tools will give you an advantage in job hunting.
