How to design Nginx location for microservice? - nginx

Question

We have 10 Microservices-based applications. Each of them has about 15 services. So, we have 150 different service URLs for our product.
My question: How to design the Nginx location?
1) One location per application
2) One location per URL
3) Other way
I thinks there are something to trade off.
a. config complexity
b. conflict location issue
c. affection when micro-service refactor
d. nginx.conf size
Could someone give me some guidance or the best practice?

Answer 1

Just to give you an example of one of my own configuration. I cannot say this is the best way to do it, but I did refer/read a lot of blogs before making this up.
worker_processes 1;
events { worker_connections 10000; }
http {
sendfile on;
gzip on;
gzip_http_version 1.0;
gzip_proxied any;
gzip_min_length 999;
gzip_disable "MSIE [1-6]\.";
gzip_types text/plain text/xml text/css
text/comma-separated-values
text/javascript
application/x-javascript;
