Shulou(Shulou.com)06/02 Report--

Recently, Red Hat released the latest survey report on the current situation of enterprise open source. Respondents said that the main use of enterprise open source is in the field of security and cloud management tools, while 83% of IT leaders said that open source tools play an important role in enterprises' use of cloud architecture. Next, Qianfeng editor will introduce several popular open source software to you.

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 、 Prometheus

Prometheus (Prom for short), 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 can be distinguished by metric name and key-value pair, and all metrics can be labeled arbitrarily.

3) the data model is arbitrary and does not need to be deliberately set to dot-delimited strings, etc.

3 、 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.

4 、 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.

5 、 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.

In addition to the above tools, the more commonly used cloud computing open source software also includes Containerd, gRPC, OpenTracing and so on. Today, with the vigorous development of cloud computing, instead of sitting idle at home, it is better to start learning immediately, and whether we can seize the opportunity when the opportunity explodes depends on whether we are ready and strong enough. So, from now on, Qianfeng 900G+ video tutorials are free! Just leave a message below. I hope it can help you grow up in the "adversity" and start the new year calmly.
