"- () Browsers use CORS to prevent websites from requesting data from different URLs. A request from a browser includes an origin header in the request message. The browser allows it if it gets to the server of the exact origin; if not the browser blocks it. We can deal with CORS issues on the backend. Cross-origin requests require that the values for origin and --- in the response headers match and the server sets it. When you add an origin to the backend code the CORS middleware only permits this URL to communicate with other origins and utilize it for cross-origin resource requests. There"

"Redis is an open-source in-memory data structure store used as a cache in front of another database. It supports various data structures such as strings hashes lists sets sorted sets with range queries bitmaps and geospatial indexes with radius queries. At its core Redis operates on a key-value store model where data is stored and retrieved using a unique key. Redis stores data in the server's main memory (RAM) ensuring low-latency data access. Unlike traditional databases that rely on disk storage Redis's in-memory nature allows it to deliver blazing-fast data retrieval and storage"

"An API management tool known as an sits between a client and a group of backend services. It performs the function of a reverse proxy by accepting all application programming interface (API) calls aggregating the different services needed to fulfill them and returning the right outcome. By using API gateways most enterprise APIs are deployed. User are typical duties that API gateways take care of on behalf of a system of API services. An API service receives a remote request and responds to it. But in reality nothing is ever that easy. When you host large-scale APIs take into account : β

"The answer is no. Even though we have [--] design patterns around [--] are mostly used in everyday development. Knowing which patterns exist overall is good but you need to know these very well. Design patterns can be divided into three main types: . These design patterns deal with object creation mechanisms trying to create objects in a manner suitable to the situation. Important patterns in this group are: πΉ: This pattern allows delegating the instantiation logic to factory classes. The Factory Method creates objects without exposing the instantiation logic to the client. πΉ: The Singleton"
