Hey developers! For the last post in the series, we’ll provision the infrastructure on AWS and deploy our API. Let’s dive in! You can check out my GitHub for the complete code.

Configure Terraform

First, we’ll define the Terraform version and set up the backend to store the state in an S3 bucket. Since Terraform doesn’t create the backend bucket automatically, you’ll need to provision it beforehand. Variables cannot be used in the backend configuration so the values to be hardcoded but feel free to change them.

    <span>}</span>
  <span>}</span>
<span>}</span>
<span>#infrastructure/versions.tf</span>

      <span>version</span> <span>=</span> <span>"~>5.0"</span>
    <span>}</span>
  <span>}</span>
<span>}</span>
#infrastructure/versions.tf

terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = "~>5.0"
    }
  }
}

    bucket = "translate-state-bucket"
    region = "us-east-1"
    key    = "terraform.tfstate"
  }
}

We’ll also create a few local variables


<span>#infrastructure/locals.tf</span>
<span>locals</span> <span>{</span>
  <span>tags</span> <span>=</span> <span>{</span>
    <span>Terraform</span>   <span>=</span> <span>true</span>
    <span>Application</span> <span>=</span> <span>"translate"</span>
  <span>}</span>
<span>}</span>
<span>#infrastructure/locals.tf</span>

<span>locals</span> <span>{</span>
  <span>tags</span> <span>=</span> <span>{</span>
    <span>Terraform</span>   <span>=</span> <span>true</span>
    <span>Application</span> <span>=</span> <span>"translate"</span>
  <span>}</span>
<span>}</span>
#infrastructure/locals.tf

locals {
  tags = {
    Terraform   = true
    Application = "translate"
  }
}

DynamoDB Table

Now we’ll define the configuration to provision the DynamoDB table. DynamoDB tables require a name, a hash_key,which should also specified as an attribute, and a billing_mode.


<span>resource</span> <span>"aws_dynamodb_table"</span> <span>"this"</span> <span>{</span>
  <span>name</span>         <span>=</span> <span>"translate-table"</span>
  <span>hash_key</span>     <span>=</span> <span>"id"</span>
  <span>billing_mode</span> <span>=</span> <span>"PAY_PER_REQUEST"</span>
  <span>attribute</span> <span>{</span>
    <span>name</span> <span>=</span> <span>"id"</span>
    <span>type</span> <span>=</span> <span>"S"</span>  <span>#string</span>
  <span>}</span>
  <span>tags</span> <span>=</span> <span>local</span><span>.</span><span>tags</span>
<span>}</span>
<span>resource</span> <span>"aws_dynamodb_table"</span> <span>"this"</span> <span>{</span>
  <span>name</span>         <span>=</span> <span>"translate-table"</span>
  <span>hash_key</span>     <span>=</span> <span>"id"</span>
  <span>billing_mode</span> <span>=</span> <span>"PAY_PER_REQUEST"</span>

  <span>attribute</span> <span>{</span>
    <span>name</span> <span>=</span> <span>"id"</span>
    <span>type</span> <span>=</span> <span>"S"</span>  <span>#string</span>
  <span>}</span>

  <span>tags</span> <span>=</span> <span>local</span><span>.</span><span>tags</span>
<span>}</span>
resource "aws_dynamodb_table" "this" {
  name         = "translate-table"
  hash_key     = "id"
  billing_mode = "PAY_PER_REQUEST"

  attribute {
    name = "id"
    type = "S"  #string
  }

  tags = local.tags
}

S3 Bucket

Next, we’ll provision the output S3 bucket by specifying a name using either the bucket or bucket_prefix field. To manage storage efficiently, we’ll add a lifecycle configuration that automatically deletes files after one day. Lifecycle configurations require the bucket name and at least one rule to define the retention policy.


<span>resource</span> <span>"aws_s3_bucket"</span> <span>"this"</span> <span>{</span>
  <span>bucket_prefix</span> <span>=</span> <span>"translate-output-"</span>
  <span>tags</span>          <span>=</span> <span>local</span><span>.</span><span>tags</span>
<span>}</span>
<span>resource</span> <span>"aws_s3_bucket_lifecycle_configuration"</span> <span>"this"</span> <span>{</span> <span># A lifecycle hook to delete files after 1 day</span>
  <span>bucket</span> <span>=</span> <span>aws_s3_bucket</span><span>.</span><span>this</span><span>.</span><span>id</span>
  <span>rule</span> <span>{</span>
    <span>id</span> <span>=</span> <span>"rule-1"</span>
    <span>filter</span> <span>{}</span>
    <span>expiration</span> <span>{</span>
      <span>days</span> <span>=</span> <span>1</span>
    <span>}</span>
    <span>status</span> <span>=</span> <span>"Enabled"</span>
  <span>}</span>
<span>}</span>
<span>resource</span> <span>"aws_s3_bucket"</span> <span>"this"</span> <span>{</span>
  <span>bucket_prefix</span> <span>=</span> <span>"translate-output-"</span>
  <span>tags</span>          <span>=</span> <span>local</span><span>.</span><span>tags</span>
<span>}</span>


<span>resource</span> <span>"aws_s3_bucket_lifecycle_configuration"</span> <span>"this"</span> <span>{</span> <span># A lifecycle hook to delete files after 1 day</span>
  <span>bucket</span> <span>=</span> <span>aws_s3_bucket</span><span>.</span><span>this</span><span>.</span><span>id</span>

  <span>rule</span> <span>{</span>
    <span>id</span> <span>=</span> <span>"rule-1"</span>
    <span>filter</span> <span>{}</span>
    <span>expiration</span> <span>{</span>
      <span>days</span> <span>=</span> <span>1</span>
    <span>}</span>
    <span>status</span> <span>=</span> <span>"Enabled"</span>
  <span>}</span>
<span>}</span>
resource "aws_s3_bucket" "this" {
  bucket_prefix = "translate-output-"
  tags          = local.tags
}


resource "aws_s3_bucket_lifecycle_configuration" "this" { # A lifecycle hook to delete files after 1 day
  bucket = aws_s3_bucket.this.id

  rule {
    id = "rule-1"
    filter {}
    expiration {
      days = 1
    }
    status = "Enabled"
  }
}

Lambda functions

We’ll start by assigning the AWSLambdaBasicExecutionRole, which grants essential permissions like creating CloudWatch logs.

To package the Python scripts for the Translate Text and Translate File endpoints, we’ll use the archive_file data resource. Since the Translate File API has dependencies, we’ll install them beforehand using a null_resource before packaging.

We’ll also create an IAM role for the Lambda functions and attach the necessary policies. Finally, we’ll define the Lambda functions using the packaged files, set the handler to main.handler, and configure the required environment variables.

API Gateway

Finally, we’ll define the API Gateway API. To handle file uploads properly, we’ll include multipart/form-data in the binary_media_types configuration, ensuring that multipart requests are base64-encoded before being sent to the Lambda function.

Additionally, we’ll configure the API resources as deployment triggers, so any changes to their properties automatically trigger a new deployment.

We’ll also define a few outputs.


<span>#infrastructure/outputs.tf</span>
<span>output</span> <span>api_url</span> <span>{</span>
    <span>value</span> <span>=</span> <span>aws_api_gateway_stage</span><span>.</span><span>this</span><span>.</span><span>invoke_url</span>
<span>}</span>
<span>#infrastructure/outputs.tf</span>

<span>output</span> <span>api_url</span> <span>{</span>
    <span>value</span> <span>=</span> <span>aws_api_gateway_stage</span><span>.</span><span>this</span><span>.</span><span>invoke_url</span>
<span>}</span>
#infrastructure/outputs.tf

output api_url {
    value = aws_api_gateway_stage.this.invoke_url
}

Enter fullscreen mode Exit fullscreen mode

To provision the infrastructure, we first configure the AWS CLI with our credentials:


aws configure
aws configure
aws configure

Enter fullscreen mode Exit fullscreen mode

Next, we initialize Terraform and apply the configuration:


terraform init
terraform apply
terraform init
terraform apply
terraform init
terraform apply

Enter fullscreen mode Exit fullscreen mode

After successful provisioning, we can access the API via the output url.

To wrap up this series, we’ve walked through writing python code for lambda functions and provisioning a complete infrastructure using Terraform and AWS.
If you’ve followed along, you should now have an API that can translate text and files running on AWS. But this is just the beginning! There’s always more to explore—whether it’s optimizing performance, integrating monitoring tools, or adding a CI/CD pipeline.

I’d love to hear your thoughts! Drop a comment below if you have questions, insights, or ideas for future topics. Thanks for reading, and happy coding!
