What is the difference between Tier and layer architecture?
Layered architecture focuses on the grouping of related functionality within an application into distinct layers that are stacked vertically on top of each other. Tiers indicate a physical separation of components, which may mean different assemblies on the same server or multiple servers.
Layers refer to the inside of a cake, which can be anywhere between two and six layers of sponge, sandwiched together by buttercream before being decorated. Tiers refer to the number of cakes of increasing size that are stacked on top of each other.
Three-tier architecture is a well-established software application architecture that organizes applications into three logical and physical computing tiers: the presentation tier, or user interface; the application tier, where data is processed; and the data tier, where the data associated with the application is ...
According to Techopedia, “3-tier architecture is a client-server architecture in which the functional process logic, data access, computer data storage and user interface are developed and maintained as independent modules on separate platforms.” A “tier” in this case can also be referred to as a “layer”.
Each tier consists of two layers, which means you'll need to bake two 6-inch cakes, two 8-inch cakes, and two 10-inch cakes. Try to find pans that are three inches deep. The cakes themselves will be two inches, but the extra room helps prevent overflow.

The three schema architecture is also called ANSI/SPARC architecture or three-level architecture. This framework is used to describe the structure of a specific database system. The three schema architecture is also used to separate the user applications and physical database.
Conceptually the three-tier architecture is linear. However, the [model-view-controller] MVC architecture is triangular: the view sends updates to the controller, the controller updates the model, and the view gets updated directly from the model.

Now, let's explore the different tiers a little more. Tier 1 firms are the largest, wealthiest, and most experienced in the industry.
Tier 1 Credit is the highest tier of credit, while Tier 3 is the lowest. If you have a credit score that has made it into Tier 1, this ranking means you will only need to provide minimal information if applying for a loan.
Facebook is abstractly a standard n-tier architecture that brings data from Facebook's internal libraries, which are processed through the Facebook logic to be outputted on the view tier of the site. Facebook engineers realized the practicality of this data beyond the confines of its container.

Tier 3 systems have an uninterruptible power supply (UPS) as an N + 1. This effectively means that the center maintains the typical system while still having another available for backup. However, a Tier 4 system expands on this. Tier 4 systems have 2N + 1 functionality.
Tier 3 provides intensive supports for individual students with more significant needs or whose needs are not sufficiently met by Tier 2 supports. There are two reasons for a student to be referred to receive Tier 3 supports: The student is not benefiting sufficiently from Tier 2 interventions.

Network layer, layer 3. The most significant protocol at layer 3 (also called the network layer) is the Internet Protocol, or IP. IP is the standard for routing packets across interconnected networks--hence, the name internet.
Although the layered architecture pattern does not specify the number and types of layers that must exist in the pattern, most layered architectures consist of four standard layers: presentation, business, persistence, and database (Figure 1-1).
What are tier 2 and tier 3 cities? According to the government, cities with a population in the range of 50,000 to 100,000 are classified as tier 2 cities, while those with a population of 20,000 to 50,000 are classified as tier 3 cities.

Three types of system architectures are identified, integrated, distributed and mixed, (partly integrated and partly distributed). It is shown that the type of interfaces defines the type of architecture. Integrated systems have more interfaces, which furthermore are vaguely defined.

Web browsers let users access SGD and display webtops. The Sun Secure Global Desktop Client displays applications that users run. The second tier contains SGD servers, which act as a gateway between the first and third tiers. The third tier contains the application servers that run users' applications.
The three-schema architecture divides the database into three-level used to create a separation between the physical database and the user application. In simple terms, this architecture hides the details of physical storage from the user.
MVVM is arguably a three layer architecture itself. Those layers all exist within the same application. "3-layer" also sometimes refers to n-tier architecture, which is more about separating the UI, the service layer, and the data layer, onto separate servers.

Mobile app architecture may incorporate several layers, but it consists of three layers in most cases. Those are the Presentation layer, the Business layer, and the Data layer.
MVVM separates the different components of the development process into three categories, model, view and ViewModel. This typically involves code markup or graphical user interfaces (GUI). MVC, or model-view-control is a way developers separate programs into these three components.
When you are ready to start adopting a microservices architecture and the associated development and deployment best practices, you'll want to follow the three C's of microservices: componentize, collaborate, and connect.
A monolithic application is built as a single unified unit while a microservices architecture is a collection of smaller, independently deployable services.
What is 3-tier model in Java?
In the three-tier model, commands are sent to a "middle tier" of services, which then sends the commands to the data source. The data source processes the commands and sends the results back to the middle tier, which then sends them to the user.

A tier is a level or a layer. If you sit in the top tier of seats at a concert, you can see the whole stage and most of the audience — but you probably have to climb lots of stairs. A tier can describe a layer of ruffles on a dress, a section of seats in a stadium, or one layer of a fancy cake.
An N-tier architecture divides an application into logical layers and physical tiers. Layers are a way to separate responsibilities and manage dependencies. Each layer has a specific responsibility. A higher layer can use services in a lower layer, but not the other way around.
Although the layered architecture pattern does not specify the number and types of layers that must exist in the pattern, most layered architectures consist of four standard layers: presentation, business, persistence, and database (Figure 1-1).

MVC is not layered. In the layered style, the usage relation is unidirectional across layers. In MVC, as you said your question, the interaction is not unidirectional. Client-server is a master-slave kind of architecture used in distributed systems, but MVC is not a form of client-server.
The American Institute of Architects (AIA) defines Five Phases of Architecture that are commonly referred to throughout the industry: Schematic Design, Design Development, Contract Documents, Bidding, Contract Administration.
