<p>A core principle of the MVC pattern is the view layer’s ignorance with respect to the model layer. Views are dumb objects. They only know how to present data to the user. They don’t know or understand what they are presenting.</p>
|

</div>

<p>MVC: Division across three code components only: Model, View, and Controller. …​ Microservices: An app is divided into a set of specialized classes that interact with each other using APIs. This model is being used by companies like Netflix, Spotify, and eBay.</p>

</div>

<div class="paragraph">

<div class="paragraph">

<p>Controller: This part manages the logic of the code and makes decisions. When the user interacts with the view, the request is processed by the controller.</p>

</div>
|

|
<div class="paragraph">

<p>It waits for the user to interact with the view to retrieve the request. Thus, it is the controller that will define the display logic, and display the next view on the screen.</p>
