Ada Packaged by IOanyT Innovations - Alma Linux 8

It was designed to be a reliable, safe, and efficient programming language for use in mission-critical and safety-critical systems, such as military and aerospace applications. Ada is named after Ada Lovelace, a mathematician who is credited with writing the first computer program. Ada has many features that make it well-suited for safety-critical and mission-critical systems. These include strong typing, modular programming, exception handling, and support for concurrent programming. Ada also has a strong emphasis on software engineering principles, such as abstraction, encapsulation, and information hiding.

Here are some of the key features of the Ada programming language:

  • Strong typing: Ada is a strongly typed language, which means that all variables must be declared with their data type before they can be used. This helps to prevent errors at compile-time and runtime.

  • Modular programming mechanisms: Ada includes packages, which are modules that can be used to organize code into reusable units. This makes it easier to manage large codebases and promotes code reuse.

  • Run-time checking: Ada includes run-time checks to help detect and prevent errors at runtime. These checks can include array bounds checking, overflow checking, and more.

  • Parallel processing: Ada includes features for concurrent programming, including tasks, synchronous message passing, protected objects, and nondeterministic select statements. These features make it easier to write parallel and concurrent code.

  • Exception handling: Ada includes a robust exception-handling mechanism that can be used to handle errors and recover from unexpected situations.

  • Generics: Ada includes support for generics, which are templates that can be used to write code that works with different data types.

  • Object-oriented programming: Ada 95 added support for object-oriented programming, including dynamic dispatch.

Overall, Ada's features make it a language that is well-suited for developing complex, mission-critical systems.


To choose a Region follow the below step:

1. Sign in to the AWS Management Console.

2. Choose a service to go to that service's console.

3. In the navigation bar, choose the name of the currently displayed Region. Then choose the Region to which you want to switch.

Step instructions for how to assess and monitor the health and proper function of the application:

1. Navigate to your Amazon EC2 console and verify that you're in the correct region.

2. Choose Instance and select your launched instance.

3. Select the server to display your metadata page and choose the Status checks tab at the bottom of the page to review if your status checks passed or failed.

To verify the installation, follow the below instructions

Step 1. Connect to SSH:

  1. Open the Amazon EC2 console at

  2. In the navigation pane, choose Instances.

  3. Select the instance and choose Connect.

  4. Choose SSH Client

  5. Copy the SSH command and paste it into the terminal.

ssh ec2-user@publicIP -i [Path of key pair file]

If it shows an access denied message run the following command, then run the above command again to connect via ssh.

chmod 400 [Path of key pair file]

Once launched in the Amazon EC2 Service, please connect to the instance via an SSH client using the ec2-user with the key pair associated at launch. Once connected as the ec2-user user, you will be able to sudo to the root user

Step 2. Verify the installation:

Follow the steps to verify the Ada installation

1. Login with ssh

2. Type the below command to check the version

3. To check the version :

gnat --version

How to use Ada in the terminal :

1. After connecting with ssh write the below command:

sudo nano helloworld.adb

3. Paste the following code into the file:

with Ada.Text_IO;

procedure HelloWorld is
   Ada.Text_IO.Put_Line("Hello, World!");
end HelloWorld;

2. After that use the below command :

gnatmake helloworld.adb

3. Then use the below command for output :


The output "Hello, World!" should appear in your terminal. That's it! You have successfully printed "Hello, World" using Ada in the terminal.

4. After using the above command then verify written the below command mentioned below image:

To monitor and assess application functions:-

a. Navigate to your Amazon EC2 console and verify that you're in the correct region.

b. Choose Instances and select your launched instance.

c. Select the server to display your metadata page and choose the Status checks tab at the bottom of the page to review if your status checks passed or failed.
