What Is Two-Tier Architecture?

Now, picture yourself as the host of an elegant dinner party. You have your guests, who are famished and want to eat, and then you have the kitchen, which is the database where all the delectable food is stored. If you had company around, you probably would want them to avoid going into the kitchen and digging through the refrigerator. To put it another way, this is where the waiter, or the application server, comes into play. The waiter's role is to liaison between the patrons and the cooks in the kitchen. The customers communicate their food preferences to the server, which then travels to the kitchen to retrieve the requested items before returning them to the customers. This is analogous to the Two-Tier Architecture in that it divides the data storage from the user interface, which refers to the visitors (the kitchen). The application server, often known as the waiter, acts as the go-between for both parties and manages all of their interactions. The Two-Tier Architecture can be described in technical terms as a client-server architecture. The client represents the user's computer, and the server represents the application server that houses the database. The client initiates communication with the server by submitting requests, and the server then answers with the required data. The user communicates with the application server one-on-one in a system with this architecture. This kind of architecture is typically utilized for more compact software packages. However, the number of users on the system increases along with the complexity of the system. In that case, the application server's performance may suffer, resulting in the requirement for a Three-Tier Architecture. Two-Tier Architecture is an easy and uncomplicated method of isolating the user interface from the data storage while simultaneously enabling communication between the two levels through an application server. It's like having a reliable waiter there to deliver your food and ensure that everything goes off without a hitch at your dinner party!
