1. Deployment Architecture The program processing flow when a browser visits a page: (1) The browser sends a request to Nginx. If it matches a static URL on the Nginx side, for example files such as js, css, or 404.html under the /static directory, Nginx returns the file directly. Other request URLs are forwarded to uWSGI for processing via the uwsgi_pass configuration.

1. Basic Concepts Docker Compose is a Docker tool for defining and running complex applications. With Docker Compose, you can define a multi-container application in a single file, then use a single command to start your application and finish all the preparation work. Docker Compose positions itself as ‘defining and running complex applications with Docker’.

1. Basic Concepts A Dockerfile is a collection of instructions for building a Docker image. Docker reads Dockerfile instructions to build an image automatically. A Dockerfile is similar to a Makefile: both are text files that organize all the instructions in the order the image is built. The command to build a Docker image:

Vagrant is suited to managing virtual machines, while Docker is suited to managing application environments. To better simulate a real runtime environment, this series of articles uses Docker and Docker Compose to build a development environment of Nginx + uWSGI + Django + MySQL + Redis + Rabbit. 1. Basic

1. Basic Website Performance Metrics Concurrency: the number of sessions the server handles per unit of time Throughput: the number of requests the server handles per unit of time Response time: the total elapsed time from when the user sends a request to when the response is fully received, made up of network transmission time, service processing time, and other parts Average response time: the average of the response times of all requests 2.
