Application tier is the brains of the application. This tier houses the business logic used to process user inputs. The application tier can also add, delete or modify data in the database tier. Database tier is the data or backend tier of a web application. It is where the information processed by the application is stored and managed.
A layer is a logic component within a software suite that accomplishes a given functionality, whereas a tier is the logical and hardware platform where such layer runs. Most of the time it makes sense to split the above-mentioned tiers to achieve further architecture flexibility, synergy, security, and efficiency.
The two-tier pattern represents a client and a server. In this scenario, the client and server may exist on the same machine, or may be located on two different machines. Figure below, illustrates a common Web application scenario where the client interacts with a Web server located in the client tier.
It’s an architecture that consists of 3 tiers: the web tier, application tier, and database tier. Web tier is a top-level tier and its main purpose is to display and collect information from the user and send its contents to the browser in the form of HTML/JS/CSS. Its main purpose is to display information to and collect information from the user.
In this step, we will make a NAT Gateway in a public subnet and route all internet traffic from the private route table to the NAT Gateway. 1. In the VPC console, go to NAT Gateways 2. Click Create NAT Gateway 3. Assign the NAT Gateway to the correct subnet — I will place mine in the “Project10-Web-02” us-east-1b subnet 4. Connectivity type — keep
In the VPC console, go to Route TablesSelect the Public Route Table. In this example, I’ll use “project10-rtb-public”Click on the Routestab.Click Edit routes. aws.plainenglish.io
Select the Private Route Table. In this example, I’ll use “Project10-App-PrivateRT” & “Project10-DB-PrivateRT”Click on the Routestab.Click Edit routes.Click Add route. aws.plainenglish.io
