Multi-Tier Network Architecture: Basic Concepts
Multi-Tier Network Architecture: Basic Concepts
A multi-tier architecture is also called n-tier architecture because the software is engineered to have the processing, data management, and presentation functions physically and logically separate. That means that these different functions are hosted on several machines or clusters, ensuring that services are provided without resources being shared and, as such, these services are delivered at top capacity. The “N” in the name n-tier architecture refers to any number from 1. Let's continue the discussion in the article below.
Multi tier architecture is simple yet very beneficial. Not only does your software gain from being able to get services at the best possible rate, but it’s also easier to manage. This is because when you work on one section, the changes you make will not affect the other functions. And if there is a problem, you can easily pinpoint where it originates.
A tier is a distinct part of hardware or software.
So, let's start things off with One Tier Architecture
a. Single Tier Systems/ One-Tier Architecture
A single computer that contains a database and a front-end (GUI) to access the database is known as Single Tier System. Generally, this type of system is used in small businesses.
The figure above shows single tier architecture.
One-tier architecture involves putting all of the required components for a software application or technology on a single server or platform. This kind of architecture is often contrasted with multi-tiered architecture or the three-tier architecture that's used for some Web applications and other technologies where various presentation, business and data access layers are housed separately.
There is one computer which stores all of the company’s data on a single database. The interface used to interact with the database may be part of the database or another program which ties into the database itself.
Now let's know what the advantages and disadvantages of this architecture are.
Advantages:
A single-tier system requires only one stand-alone computer. It also requires only one installation of proprietary software which makes it the most costeffective system available.
Disadvantages:
It can be used by only one user at a time. A single tier system is impractical for an organization which requires two or more users to interact with the organizational data stores at the same time.
Well, that's all on single tier architecture. We will discuss 2 tier architecture in the next article. Stay tuned for that.
