Introduction to Pulumi

Pulumi is an open-source infrastructure as code (IaC) tool that allows you to define, deploy, and manage cloud infrastructure using familiar programming languages such as Java, JavaScript, Python, and Go. With Pulumi, you can treat your infrastructure code just like any other software code, taking advantage of the rich ecosystems and tools available in these languages.

Pulumi provides a declarative way to describe your cloud infrastructure using code. You can define resources, such as virtual machines, databases, networks, and storage, in your preferred programming language and Pulumi will provision and manage these resources in your cloud provider.

Here's an example of a simple Pulumi program written in Java:

1import com.pulumi.Pulumi;
2import com.pulumi.aws.ec2.Instance;
3
4public class Main {
5    public static void main(String[] args) {
6        Instance instance = new Instance("my-instance", new InstanceArgs.Builder()
7                .instanceType("t2.micro")
8                .ami("ami-0c94855ba95c71c99")
9                .build());
10        Pulumi.export("instanceIp", instance.getPublicIp());
11    }
12}

class Main {

    public static void main(String[] args) {

        String message = "Hello, World!";

        System.out.println(message);

    }
