分层
最常见的架构模式,将系统在横向维度上切分成几个部分,每个部分单一职责。网站一般分为三个层次:应用层

With all of the love and proclamations about REST, we can sometimes forget that it’s simply one of many options. REST is a very good standard for a wide variety of APIs, but there are other API design styles
for more nuanced scenarios.
To help API developers make sense of which API design style to use and for what situation, let’s look at REST

, and Webhooks
. We’ll offer real world examples
of REST, GraphQL, gRPC, and Webhooks in practice, and analyze their strengths and weaknesses to highlight what makes each option a good choice.
Kubernetes and Docker Swarm are probably two most commonly used tools to deploy containers inside a cluster. Both are created as helper tools that can be used to manage a cluster of containers and treat all servers as a single unit. However, they differ greatly in their approach.
Linux 系统用来用去还是发现ubuntu用的最舒服,毕竟用了从14.04 一直用到了18.04 。用了三年多了。下面就直接记录下。我这边优化系统的全部命令,方便下次装机使用。
Manjaro是一款基于Arch Linux、对用户友好、全球排名第1的Linux发行版。
在Linux圈,Arch的确是一个异常强大的发行版。它有3个无与伦比的优势:
在PHP生命周期的各个阶段,一些与服务相关的操作都是通过SAPI接口实现。这些内置实现的物理位置在PHP源码的SAPI目录。这个目录存放了PHP对各个服务器抽象层的代码,例如命令行程序的实现,Apache的mod_php模块实现以及fastcgi的实现等等。
