Microservice Architectures

Decoupling is the Primary Benefit of Microservice Architectures

• Development
• Deployment
• Dependencies

Interest Over Time

Client Challenge

• Keeping track of what to call

API Gateways

API Gateways replace tight coupling with loose coupling

• Help manage large numbers of microservices
• Hide infrastructure complexity from clients

Reverse Proxy

• Handles incoming requests from clients
• Calls a service to get the data to satsify the request
• Returns the data to the client

An API Gateway is a Reverse Proxy

NGINX Documentation

NGINX Concepts

• Modules
• Directives
• Contexts
• Events
• Upstreams

NGINX Architecture

• Multiprocess vs. Multithread
  • One master process
  • Multiple worker processes

Modules

Directives

Contexts

• main
• http
• server
• upstream
• location
• mail

Variables

NGINX Configuration

nginx.conf

worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       8080;
        server_name  localhost;

        location / {
            root   html;
            index  index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }

}

NGINX Reverse Proxy Configuration

server {
    listen       8080;
    server_name  localhost;

    location /server-a/ {
        proxy_pass http://127.0.0.1:3002; 
    }

    location /server-b/ {
        proxy_pass http://127.0.0.1:3004; 
    }
}
