00:00:01 Now that we've covered how databases and APIs work, let's zoom out and talk about the big picture.
00:00:08 How to structure your backend code.
00:00:11 The backend architecture is all about the design and the structure of your app.
00:00:16 It's not rocket science, but it is crucial for building scalable, maintainable systems.
00:00:22 There are a few popular architectures that developers follow depending on their project's needs.
00:00:28 So let me break them down.
00:00:29 The first and the most popular one is the monolithic architecture.
00:00:33 In a monolithic architecture, all components of your application are combined into a single unified code base.
00:00:40 Makes sense, right?
00:00:42 Everything's in one place.
00:00:43 And therefore, the backend handles everything, from user management to business logic and database interactions.
00:00:50 It's simple to develop and deploy, and it's easier to debug since everything's in one place.
00:00:56 But it can get a bit messy if the app grows, and scaling specific parts of the app can be tricky.
00:01:02 But as I said, it has been the go-to architecture for years, and it's exactly what I'll teach you how to build today.
00:01:08 And the second type of backend architectures are microservices.
00:01:13 In a microservices architecture, the application is broken down into smaller, independent services.
00:01:20 Each service handles a specific business function, like authentication, payment, or notifications, all separated, and they communicate with each other
00:01:31 via APIs.
00:01:32 So no longer do you need just a single front-end and back-end connection through an API, now every single part of the back-end also needs to communicate
00:01:40 through its own APIs.
00:01:42 making microservices great for large-scale applications or enterprise systems where flexibility and scalability are important.
00:01:51 And then there's the serverless architecture that lets you write code without worrying about the underlying infrastructure.
00:01:58 Your cloud provider like AWS Lambda and nowadays even Versel handles provisioning, scaling and server management for you.
00:02:07 So if you build a full stack Next.js application, you've probably already worked with serverless backends without even realizing it.
00:02:14 Serverless is perfect for startups, rapid prototyping, or apps with spiky traffic because you can very easily increase the capacity that your server action
00:02:24 can handle.
00:02:24 And there are other architectures too, but these three are the most popular and most widely used today.
00:02:30 So if you'd like me to cover microservices or serverless architecture in detail someday, just drop a comment below and let me know.
