Magento 2 offers 6 types of products so that store owners could choose among them according to the specifics of their business. Let’s take a look at each of the 6 types of products in Magento 2 and learn the basic methods for different types of products and some additional functionality for particular types.
Product types in Magento 2
There are 6 types of products:
1) Simple Product. It’s the most popular basic type of products. It corresponds to the existing product with a unique SKU (Store Keeping Unit).
2) Virtual Product. This type of product is used to create products that are not physically present on the store (paid subscriptions, services, insurance, etc.).
3) Configurable Product. This type allows you to create products with a list of variations. For example, a sports T-shirt of different colors and sizes. Each variation of a configurable product corresponds to a Simple Product, which has its own unique SKU, which allows you to keep track of the residuals for each option.
4) Grouped Product. This type allows you to combine into sets individual Simple or Virtual Products, that are somehow related to each other. As a result, a buyer gets an opportunity to buy all the needed products at once, instead of buying them separately. On the page of a Grouped Product customers can choose particular products that they would like to purchase from the set, as well as their quantity. The selected products are added to cart as individual items.Here is an example of a Grouped Product. There are 6,8 and 10-foot Yoga Straps. Customers can choose the one they need and enter the required quantity into the Qty box on the right.
5) Bundle Product. This type of product allows customers to independently “create” a product using a set of options. Here is an example of a yoga kit.
Each option is a Simple Product or a Virtual Product. Before adding this product to cart, buyers must first customize it using a set of predefined options, and the final price will depend on their choice.
The SKU and Weight attributes can be fixed or dynamic. The price for the Bundle Product can be set as Price Range (a price range from minimum to maximum) or As Low As (the lowest possible price). Administrators can specify how parts of the Bundle Product will be delivered — together or separately.
6) Downloadable Product. This type of product is used to create digital products that can be represented by one or multiple files and can be downloaded by customers.
Virtual and Downloadable Products have no weight, therefore there is no need to choose the delivery method for these products at checkout. Also, Virtual and Downloadable Products do not have the In Stock attribute.
To get all the products of a particular type, you can use the Magento\Catalog\Model\ResourceModel\Product\Collection class:
Type the name of the required product as a second parameter: bundle, configurable, downloadable, grouped, simple or virtual.

It should also be noted that although methods like getRelationInfo, getAssociatedProducts, getChildrenIds, getParentIdsByChild, etc. are common to all types of products, they return an empty array for non-composite types (Simple, Virtual). The logic of these methods is implemented in classes of complex types according to the specifics of this type.
