Simple Factory design pattern in java

Factory pattern is a kind of Creational Pattern.

How the Factory work:

Given: Somewhere people write First name first and then last name but some where peole use backward way. If we fill a full name with comma, then the word is place before comma will be last name, and if we enter a full name without comma then the last word is last name.

In the below figure, there's a parent class Namer, and two child classes: FirstFirst and LastFirst. The NameFactory decides which sub classe to return depending on the input.

What is API Gateway?

What does API gateway do? The diagram below shows the detail. Step 1 - The client sends an HTTP request to the API gateway. Step 2 - The API gateway parses and validates the attributes in the HTTP request. Step 3 - The API gateway performs allow-list/deny-list checks. Step 4 - The API gateway talks to an identity provider for authentication and authorization. Step 5 - The rate limiting rules are applied to the request. If it is over the limit, the request is rejected. Steps 6 and 7 - Now that the request has passed basic checks, the API gateway finds the relevant service to route to by path matching. Step 8 - The API gateway transforms the request into the appropriate protocol and sends it to backend microservices. Steps 9-12 : The API gateway can handle errors properly, and deals with faults if the error takes a longer time to recover (circuit break). It can also leverage ELK (Elastic-Logstash-Kibana) stack for logging and monitoring. We sometimes cache data in the API gatew...
