How to create outlook signature

Hi, my name is Jason K a full-stack developer in South Korea We have talked a lot about the front end so far You know what HTML, CSS, and JavaScript are And I showed you some examples to help you understand them better But you know that web development consists of front-end and back-end This time, I will show you how the backend works The backend receives requests from a client, and then it generates and responses back to the client Just like the frontend, the backend has three different parts. server, application, and database The server is the computer that receives requests from a client And this computer runs an application that contains logic about how to respond to different requests The database is where all the information is stored The application accesses this database to get all the information that it needs and then generate appropriate responses for the client A client and a server communicate with each other using an API which stands for Application Programming Interface API contains the information about how a client should make a request and how the server must respond to the specific request It contains information like endpoint and data formats that the server and client must follow Let's say you are writing letters to your friend John to ask about something John talked about the cupcake that he tried in Chicago and a cookie from New York And you want some information about that cupcake Then you would write to John's address and ask him where exactly in Chicago where he got that cupcake from If you put in the wrong address or ask him about the cookie from New York, you are not gonna get the information you want Here, John's address is the endpoint, and the cupcake from Chicago is the data formats A client must use the correct endpoint along with the correct data format to retrieve the information that he wants Through the API, the application knows which information a client wants and returns the requested information. Then where is this server? The server is the computer that receives requests from a client When you think about a computer, probably an electronic device comes to your mind But today, a lot of servers are usually run on clouds Cloud is a virtual device that allows you to retrieve resources through the Internet Clouds are more accessible, reliable, and convenient than physical devices We are also going to use cloud services as when we start writing out codes I am going to show you how to deploy your projects using clouds There are a lot of companies that offer cloud like AWS, Google Cloud, Microsoft Azure But Korean born NAVER Cloud is very promising in Asia I am going to show some cool features that NAVER CLOUD offers that can make your life a lot easier As always, if you want to know about something specific, please leave them in the comments below so I can answer your questions Thank you, and stay tuned
