SST - the part of the infrastructure that may be legal

Cloud providers are increasingly crucial, and even basic familiarity is a significant advantage. This article explores SST, a tool offering streamlined abstractions over AWS CDK, which translates code into CloudFormation templates.

CloudFormation Basics

While a deep dive into CloudFormation isn't the focus, understanding its purpose is key: AWS CloudFormation automates AWS resource provisioning and configuration, saving time and effort. You define your desired resources (e.g., EC2 instances, RDS databases) in a template, and CloudFormation handles the rest, including dependency management. However, creating CloudFormation templates can be counterintuitive, highlighting the value of higher-level abstractions like SST.

Getting Started with SST

Let's use Next.js to demonstrate SST's power and its interaction with CDK/CloudFormation.

1. Create a Next.js app:

   <code class="language-bash">npx create-next-app@latest aws-nextjs
   cd aws-nextjs</code>

2. Initialize SST:

   <code class="language-bash">npx sst@latest init</code>

   SST generates a configuration file. For our example:

   <code class="language-javascript">const bucket = new sst.aws.Bucket("MyBucket", {
     access: "public"
   });</code>

   This creates a publicly accessible S3 bucket named "MyBucket" after CloudFormation template compilation.

3. Configure Next.js to use the bucket:

   <code class="language-javascript">new sst.aws.Nextjs("MyWeb", {
     link: [bucket]
   })</code>

   This concisely integrates the bucket into the Next.js deployment, managing the underlying infrastructure details. The source code reveals further infrastructure components handled automatically:

Lambda Functions with SST

AWS Lambda functions are short-lived, event-driven functions. CDK offers various deployment methods, but SST simplifies this further:

SST provides abstractions for Node.js configuration, versioning, and bundling options using esbuild:

Ultimately, this simplifies deployment to:

<code class="language-javascript">return new lambda.Function(
  transformed[0],
  {
    ...transformed[1],
    ...(dev
      ? {
        description: transformed[1].description
          ? output(transformed[1].description).apply(
            (v) => `${v.substring(0, 240)} (live)`,
          )
          : "live",
        runtime: "provided.al2023",
        architectures: ["x86_64"],
      }
      : {}),
  },
  transformed[2],
);</code>

SST's abstractions significantly streamline the process, making infrastructure management more efficient.
