==CLOUD improvement==
[[File:WebModelDiagram.drawio.png]]
*Formalize your infrastructure as much as possible for more flexibility, low complexity and less technology lock-in.
*Use a name server able to handle the position of your customers like GDNS.
*Use a minimal instance and use a network load balancer like LVS. Monitor the global load of your instances and add/delete dynamically as needed.
*Or, many providers have dynamic computing services. Compare the prices. But take care about the technology lock-in.
*Use a very efficient TLS decoder for the frontend like the HAPROXY decoder.
*Use very fast http cache like VARNISH.
*Use a big cache for big files like Apache Traffic Server.
*...
*Use a REVERSE PROXY with TLS decoder like ENVOY for more services compatibility.
*Use serverless service for standard runtimes like Java, Python and PHP. But beware of certain incompatibilities and a lack of consistency over time.
*...
*Each time you need dynamic computing power think about load balancing or native service from the providers (caution about providers services!)
*...
*Try to use open source STACKs as much as possible.
*...
*Use cache for your databases like MEMCACHED
