Types of eCommerce Architecture

#1. Two-tier

A two-tier design is the simplest architectural model. In this, UI runs on the client’s side while data is stored on the server side.

The logic of the business application can operate on either the side – the client or the server. 

This way, the client and server run independently of one another.

Client processes give customers an interface that collects and displays data on their computers. The presentation layer refers to this section of the application. Server processes connect to the company’s data store.

The data layer refers to this element of the application. 

The business logic that validates data, maintains security and permissions and executes other business processes might be stored on the client or the server. 

#2. Three-tier AWS E-commerce Architecture

Despite the two-tier architecture’s simplicity may be appealing to some organizations, others may require more features. 

Thus, the three-tier eCommerce architecture has the same components as the two-tier but adds a third tier: the business side.

Each of the three layers — presentation, business, and data — works as a separate module on a different server; although they work together to construct the overall architecture.

The three-tier design is superior at collecting data and improving decision-making processes to the two-tier architecture. 

Let’s take a glance at each of them in more detail.

Presentation layer

The presentation layer is where the three-tier architecture begins. 

Because this is frequently the section that the consumer sees, it is typically referred to as a graphic user interface or GUI. 

The presentation layer consists of two parts: the front end and the back end. MVC Razor, Vue.js, React, and Angular are among the frameworks and libraries used. 

In practice, this layer encompasses the start and end of processing requests or data. When it comes to processing requests, this layer employs validation to ensure that all relevant data is retrieved.

Business layer

The application’s business layer, also known as the application or service layer, lies at its heart. 

It gathers and processes data using business logic; which is a collection of business rules, and it can also add, delete, or alter data in the data layer.

The business layer, for example, would be in charge of recording consumer preferences as they browse the website, look at products, and make transactions.

That said, the next time the customer login onto the website, the business layer will have already preserved the user’s selected shipping and payment methods, saving from re-entering them.

Data layer

The data tier, often known as the database layer; is the final layer in which data is stored and requests are processed. 

A relational database management system, such as LINQ or SQL, can be used to store this data. 

The data management component ensures that data is consistent across the distributed environment; while the middle layer houses the centralized process logic, which makes administration easier by localizing system functionality.

#3. SaaS

Software as a Service (SaaS) is a type of architecture that hosts software and data in the cloud and makes it available through a variety of web browsers.

Because the provider is in charge of maintenance, hosting, and site performance, SaaS allows you to have your site up and running in no time, with a full product catalog and backend capabilities.

Furthermore, because updates are made in real-time, a SaaS design allows retailers to swiftly upgrade their websites to the most recent version. 

Moreover, merchants are spared the trouble of having to change their existing settings every time the platform is updated.


What does AWS identify as?

Amazon Web Services classifies as an extensive cloud computing platform, which comprises infrastructure as a service (IaaS), platform as a service (PaaS), and packaged software as a service (SaaS) solutions.

Types of AWS architecture levels

Basic AWS Services for eCommerce

Now that we know what eCommerce system architecture, let’s discover the services offered by AWS to build your eCommerce website architecture.

1. Signup and authentication

You can use your node.js javascript code to handle user signup and authentication in your eCommerce system by storing user credentials and information in a MySQL database and managing user signup and authentication using your node.js javascript code.

2. Notifications system

To keep your customers up to date on everything they’re doing on your app, such as;

  • what you’re doing with their orders
  • when they’ll be shipped, and
  • when they’ll arrive

you’ll need to send a lot of messages to them via WhatsApp, SMS/Text, e-mail, and in-app notifications.

3. Search

The importance of search as a product discovery strategy on your eCommerce application influences how you choose a search algorithm for your site’s product search. 

If you have a small number of products and aren’t adding new ones every day or regularly, a sophisticated search engine may be a waste of time and resources. 

However, if you have a large number of products and want customers to be able to accurately search for them, you should invest in a sophisticated search engine that can better understand their intent.

4. Recommendation engine

Customers should be shown recommendations based on what they are looking at on your website, such as Amazon’s “customers who bought this also bought this section”, or based on “buy again” and here is your browsing history.

Using a MySQL database, you can create such a recommendation engine by performing queries on previous orders and displaying the results on the customer’s results page. 

If your consumers are few and don’t mind the search query taking a long time to load, this will work well.

5. 3rd Party Integrations

You must integrate your eCommerce applications with other systems such as a payment gateway to accept payments from customers, an inventory management system to display available products to customers, logistics and shipping to ship orders to customers and manage returns; CRM to manage customer history, and finance to manage all financial information about a transaction conducted on your website. 

6. Data Warehousing and Analytics

You’ll need a system that allows you to examine all of the data coming in from multiple sources. 

You should be able to see all of the visitors coming in, how much time they spend on the site, what they buy or abandon, which products are performing well, which marketing campaigns are working and which are not, which ads are performing, or not, and so on. 

You should also be able to analyze the demographics of the customers and their performance and preferences by demographics. 

Add in an examination of shipping and handling as well as inventory to determine what’s in stock, what’s not, how long it takes to complete an order, etc.

AWS services for eCommerce

Now that we know the components of the architecture for your eCommerce, let’s break down the services offered by AWS to fulfil these requirements.

1. Server & Databases

1.1. Amazon EC2 Service

With Amazon EC2, you won’t need an on-site server. There are more benefits to it as well – such as;

  • Easy OS installation & maintenance
  • Instant hardware setup
  • Higher scalability
  • Cost-Effective

The major advantage of adopting EC2 instances for eCommerce sites is that they are charged based on usage, extra resources are automatically allocated to them during peak usage, and the prices are greater only during those periods.

Choosing the Right AWS Architecture for E-commerce

There’s no one-size-fits-all solution when it comes to AWS architecture. The ideal setup depends on your specific needs and business size. Here’s a breakdown of some key considerations:

  • Traffic Volume: Do you have a small, established store, or are you expecting high volumes from day one? Scalability becomes more critical with higher traffic.
  • Data Storage Needs: The type and amount of product data you store will influence your storage choices on AWS.
  • Security Requirements: The level of security needed depends on the type of data you handle (e.g., credit card information). AWS offers various security features to meet your specific needs.
  • Performance Expectations: How crucial are lightning-fast loading times for your target audience? CDNs and optimized server configurations play a vital role in website performance.
    Here’s a simplified approach to choosing your AWS architecture:
  • Small-Scale Stores: For startups or businesses with modest traffic, consider a basic architecture using S3 for storage, EC2 instances for compute power, and CloudFront for content delivery.
  • Medium-Scale Stores: As your business grows, explore managed services like Amazon DynamoDB for product catalogs and Amazon RDS for databases.
  • Large-Scale Stores: For high-traffic e-commerce giants, leverage a combination of services like Elastic Beanstalk for application deployment, Amazon Aurora for scalable databases, and Auto Scaling for automatic resource provisioning.

Remember, this is just a starting point. AWS offers a wealth of resources – documentation, whitepapers, and solution architects – to help you design the perfect architecture for your unique e-commerce needs.
