Using Aws Ec2 With Waf

In this solution, we will set up an AWS EC2 instance with AWS WAF (Web Application Firewall) using Pulumi in TypeScript. The key services involved in this solution are AWS EC2, AWS WAF, and Pulumi. AWS EC2 provides scalable computing capacity in the cloud, while AWS WAF helps protect web applications from common web exploits. Pulumi is an infrastructure as code tool that allows us to define and manage cloud resources using programming languages.

Introduction

In this solution, we will set up an AWS EC2 instance with AWS WAF (Web Application Firewall) using Pulumi in TypeScript. The key services involved in this solution are AWS EC2, AWS WAF, and Pulumi. AWS EC2 provides scalable computing capacity in the cloud, while AWS WAF helps protect web applications from common web exploits. Pulumi is an infrastructure as code tool that allows us to define and manage cloud resources using programming languages.

Step-by-Step Explanation

Step 1: Set up Pulumi Project

First, we need to set up a new Pulumi project. We will create a new directory for our project and initialize it with Pulumi.

Step 2: Create an AWS EC2 Instance

Next, we will create an AWS EC2 instance. We will define the instance type, AMI, and other necessary configurations.

Step 3: Set up AWS WAF

After creating the EC2 instance, we will set up AWS WAF. We will create a WebACL and define rules to protect our web application from common web exploits.

Step 4: Associate WAF with EC2

Finally, we will associate the AWS WAF WebACL with our EC2 instance to ensure that our web application is protected.

Key Points

• AWS EC2 provides scalable computing capacity in the cloud.
• AWS WAF helps protect web applications from common web exploits.
• Pulumi allows us to define and manage cloud resources using programming languages.
• We will set up an EC2 instance, create a WAF WebACL, define rules, and associate the WebACL with the EC2 instance.

Conclusion

In this solution, we successfully set up an AWS EC2 instance with AWS WAF using Pulumi in TypeScript. This setup helps ensure that our web application is protected from common web exploits while providing scalable computing capacity. Pulumi makes it easy to define and manage cloud resources using familiar programming languages.

Full Code Example

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Create an EC2 instance
const ec2Instance = new aws.ec2.Instance("myInstance", {
    ami: "ami-0c55b159cbfafe1f0", // Amazon Linux 2 AMI
    instanceType: "t2.micro",
    tags: {
        Name: "myInstance",
    },
});

// Create a WAF WebACL
const webAcl = new aws.waf.WebAcl("myWebAcl", {
    defaultAction: {
        type: "ALLOW",
    },
    metricName: "myWebAclMetric",
    rules: [
        {
            action: {
                type: "BLOCK",
            },
            priority: 1,
            ruleId: new aws.waf.Rule("myRule", {
                metricName: "myRuleMetric",
                predicates: [
                    {
                        dataId: "exampleDataId",
                        negated: false,
                        type: "IPMatch",
                    },
                ],
            }).id,
        },
    ],
    tags: {
        Name: "myWebAcl",
    },
});

// Export the instance ID and WebACL ID
export const instanceId = ec2Instance.id;
export const webAclId = webAcl.id;
