If you had done speed-up by application level, then we recommend to make more speed by network and infrastructure level.

Azure IIS server and Windows NT

Scale-up web/app/DB server
Scale-out web/app/DB server
DNS routing
Load balance by Azure Front door
Cash by CDN Azure Front door or Azure CDN
L4 level load balancing with Azure Gateway


Sizing & Load balancing

You can monitor CPU% , Memory% and response time for proper sizing of Azure server. Additionally you can set load balancer and calucurate proper latency sensitivity for most appropriate workload balancing.


Select what is the most important thing

we have 20,000,000 request per month therefore cut off all the js, css, html, php including themes and plugins, put off all the mesurement tools like google analytics, clearlity, hotjar , google tag manager and so on.

If javascripts prevent 1 second, then we cost 20,000,000 second in a month. That means we we are costing 10 month of one single person’s life. 1year=31,104,000 second


Multi-Layer orchestration

Access explosion cost us $800k USD per week by 30 premium servers. But after cloud-native performance tuning into DNS, Network, App, OS,DB,CDN, Loadbalance, WAF, then we reduced 98% of server cost. eventually achieved $20k USD per week by 1 single server.
