How To Create SNS Topic In AWS In Using Terraform

Amazon Simple Notification Service (SNS) is a fully managed messaging service given by Amazon Web Services (AWS), offering a versatile and reliable solution for sending notices and messages to different endpoints or subscribers. SNS points act as correspondence channels to which messages can be distributed and dispersed to numerous subscribers, including email addresses, SMS endpoints, HTTP/S endpoints, AWS Lambda functions, and more.

In the present circulated systems architectures, where decoupled and event driven models are predominant, SNS assumes an essential part in working with correspondence between various parts of an application. By coordinating SNS into your infrastructure utilizing Terraform, a infrastructure as-code tool, you can automate the creation and the executives of SNS subjects, ensuring consistency, dependability, and scalability in your notification work processes.

In this guide, we will investigate how to make SNS topic in AWS utilizing Terraform, giving step by step guidelines, meanings of key terminologies and FAQs to help you comprehend and carry out SNS topics successfully in your infrastructure automation work processes. Whether you’re a DevOps engineer, a framework director, or a developer, understanding how to use SNS and Terraform together can improve the efficiency and reliability quality of your notification mechanisms in AWS.

What Is SNS?

Amazon Simple Notification Service (SNS) is a completely overseen informing administration given by Amazon Web Administrations (AWS) that empowers the distribution and conveyance of messages to various endpoints or endorsers. SNS goes about as an adaptable and dependable correspondence administration for sending notifications, alerts, and messages in dispersed systems and applications.

SNS works around the idea of points, which act as communication channels for messages. Publishers can publish messages to these points, and subscribers can get these messages through different conventions, including email, SMS, HTTP/S, AWS Lambda, SQS (Simple Queue Service), and that’s just the beginning. SNS points support numerous endorsers, considering the dispersion of messages to various endpoints all the while.

Key Features Of AWS SNS

The following are the key features of AWS SNS:

• Reliability: SNS ensures solid message conveyance via automatically retrying message conveyances and giving repetitive message stockpiling across various accessibility zones.
• Scalability: SNS scales flawlessly to accommodate any message volume, permitting you to all the while send notices to a great many subscribers.

What Is Terraform?

Terraform is an open-source Infrastructure as Code (IaC) tool created by HashiCorp. It allows users to characterize and provision infrastructure resources like virtual machines, networks, storage, and services utilizing a declarative configuration language. Terraform enables you to manage and automate the whole lifecycle of your infrastructure across different cloud suppliers and on-premises conditions.

Key Features Of Terraform

The following are the key features of Terraform:

• Declarative Configuration Language: Terraform utilizes a declarative language called HashiCorp Configuration Language (HCL) to define infrastructure resources and their setups. With HCL, you depict the ideal condition of your infrastructure as opposed to scripting the succession of activities expected to accomplish that state.
• Infrastructure as Code (IaC): Terraform regards infrastructure as code, allowing you to form control your infrastructure configurations, work together with colleagues, and apply software advancement best practices, for example, code reviews and automated testing to your infrastructure code.
• Resource Graph: Terraform fabricates a reliance chart of your infrastructure resources in light of their interdependencies and connections characterized in the configuration files. This empowers Terraform to decide the request for resource creation, update, or deletion to ensure consistency and keep away from conflicts.
• Providers: Terraform supports different cloud providers , (for example, AWS, Azure, Google Cloud Platform, and others) as well as different infrastructure services and platforms. Every supplier offers a bunch of asset types and APIs that Terraform interfaces with to oversee infrastructure resources.

Create SNS topic In AWS Using Terraform: A Step-By-Step Guide

Step 1: Launch An Instance

• Launch an Amazon EC2 instance with Amazon Linux.
• Ensure that your security groups and network configurations allow inbound traffic on the ports necessary for your Java application to function (e.g., port 8080 for a web application).

• Now connect with git bash terminal by using SSH Client

Step 2: Install Terraform

• Now install terraform packages from official site

sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/AmazonLinux/hashicorp.repo

sudo yum -y install terraform

Step 3: Create And Write Terraform Script To Create SNS Topic

• Create a file with .tf extension in that file write a script by using following command
• vi <filename.tf> “.tf” is a extension for terraform. Without this extension we cannot create a terraform file and create a infrastructure

Provider Configuration

• This section specifies the AWS provider and sets the region to “us-east-1”. The provider block configures the authentication details and default settings for interacting with AWS.

provider "aws" {
  region = "us-east-1"  # Specify your desired AWS region
}

Create SNS Topic

• Define the SNS topic resource in your Terraform configuration file, specifying the name for the topic.

resource "aws_sns_topic" "example_topic" {
  name = "example-topic"  # Specify your desired Name
}

Step 4: Now Initialize Terraform And Execute Terraform Commands

• Now initialize terraform by using following command

terraform init

• Now execute terraform execution commands by using following commands

terraform fmt 
terraform validate
terraform plan

• Now execute terraform apply command by using following command

terraform apply --auto-approve

• The following screenshot shows that we successfully created a sqs topic in aws using terraform

Conclusion

Amazon Simple Notification Service (SNS) remains as an essential part inside the AWS environment, offering a scalable, reliable, and completely managed messaging service for sending notifications and messages to different endpoints or subscribers. SNS subjects act as correspondence channels for messages, permitting distributers to all the while appropriate messages to various endorsers. With its adaptability, dependability, and coordination abilities, SNS simplifies on the most common way of sending messages across appropriated frameworks and applications, working with correspondence and enabling constant notifications, alerts, and updates.
