How to host a Static Website in AWS S3 - CodeBabel

Hello All! Welcome back to the third article in the AWS Series! As we already know, AWS S3 offers low cost, high performance, highly scalable, unlimited cloud storage with a pay-as-you-go approach. But, apart from being a storage option, it can also be used to host static web content. In this article, we will discuss how to host a static website in AWS S3.

Below is the overview of the steps for doing that:

Creating a bucket

Step1: First let’s create a bucket. For that, let’s first login to AWS console, and then select S3 under ‘Storage’ from the AWS ‘Console Home’.

select S3

select S3

Step2: Next, from the S3 console, let’s click on the ‘Create Bucket’ icon in the Amazon S3 console.

Creating New Bucket

Creating New Bucket

A pop up window appears wherein we enter the bucket details. Here, let’s consider the bucket name as ‘codebabel-static-website-demo and the region can be according to the requirement. Here we have chosen the default region ‘US EAST ohio’. Let’s leave everything to default settings by clicking on “Next” option. In the ‘review’ page, let’s review our configurations and click on ‘Create bucket’ to create the S3 bucket.

We can see the newly created S3 bucket in the AWS S3 console.

Created Bucket can be viewed in S3 Dashboard

Step3: For this demo, we have created a simple static website in HTML. It consists of an **index.html **file which has two web pages and an **error.html**file which throws an error message when something goes wrong. We also have some .css files for formatting. Now let’s upload these files in the AWS S3 demo bucket.

For this, let’s click on our S3 bucket and click on the “upload” option under the “overview” icon. We can either add or drag and drop the required files. We can also set permissions for each of the files while uploading by clicking the “Next” icon which we will discuss later in this article. For now, we will only upload the files by clicking “Upload“. Let’s upload all our files this way.

Enabling static website hosting

Step4: Let’s click on our S3 bucket, and go to Properties -> Static website hosting.

We can see the generated endpoint URL to access our static website, as soon as we select this option. Now below that, we will mention the following: “Index document = index.html, error document = error.html“.

AWS Cost Allocation Tags and Cost Reduction

Bob had just arrived in the office for his first day of work as the newly hired chief technical officer when he was called into a conference room by the president, Martha, who immediately introduced him to the head of accounting, Amanda. They exchanged pleasantries, and then Martha got right down to business:

“Bob, we have several teams here developing software applications on Amazon and our bill is very high. We think it’s unnecessarily high, and we’d like you to look into it and bring it under control.”

Martha placed a screenshot of the Amazon Web Services (AWS) billing report on the table and pointed to it.

“This is a problem for us: We don’t know what we’re spending this money on, and we need to see more detail.”

Amanda chimed in, “Bob, look, we have financial dimensions that we use for reporting purposes, and I can provide you with some guidance regarding some information we’d really like to see such that the reports that are ultimately produced mirror these dimensions — if you can do this, it would really help us internally.”

“Bob, we can’t stress how important this is right now. These projects are becoming very expensive for our business,” Martha reiterated.

“How many projects do we have?” Bob inquired.

“We have four projects in total: two in the aviation division and two in the energy division. If it matters, the aviation division has 75 developers and the energy division has 25 developers,” the CEO responded.

Bob understood the problem and responded, “I’ll see what I can do and have some ideas. I might not be able to give you retrospective insight, but going forward, we should be able to get a better idea of what’s going on and start to bring the cost down.”

The meeting ended with Bob heading to find his desk. Cost allocation tags should help us, he thought to himself as he looked for someone who might know where his office is.

How To Unite AWS KMS with Serverless Application Model (SAM)

The Basics

AWS KMS is a Key Management Service that let you create Cryptographic keys that you can use to encrypt and decrypt data and also other keys. You can read more about it here.

Important points about Keys

Please note that the customer master keys(CMK) generated can only be used to encrypt small amount of data like passwords, RSA key. You can use AWS KMS CMKs to generate, encrypt, and decrypt data keys. However, AWS KMS does not store, manage, or track your data keys, or perform cryptographic operations with data keys.

You must use and manage data keys outside of AWS KMS. KMS API uses AWS KMS CMK in the encryption operations and they cannot accept more than 4 KB (4096 bytes) of data. To encrypt application data, use the server-side encryption features of an AWS service, or a client-side encryption library, such as the AWS Encryption SDK or the Amazon S3 encryption client.

Scenario

We want to create signup and login forms for a website.

Passwords should be encrypted and stored in DynamoDB database.

What do we need?

  1. KMS key to encrypt and decrypt data
  2. DynamoDB table to store password.
  3. Lambda functions & APIs to process Login and Sign up forms.
  4. Sign up/ Login forms in HTML.

Lets Implement it as Serverless Application Model (SAM)!

Lets first create the Key that we will use to encrypt and decrypt password.

KmsKey:
    Type: AWS::KMS::Key
    Properties: 
      Description: CMK for encrypting and decrypting
      KeyPolicy:
        Version: '2012-10-17'
        Id: key-default-1
        Statement:
        - Sid: Enable IAM User Permissions
          Effect: Allow
          Principal:
            AWS: !Sub arn:aws:iam::${AWS::AccountId}:root
          Action: kms:*
          Resource: '*'
        - Sid: Allow administration of the key
          Effect: Allow
          Principal:
            AWS: !Sub arn:aws:iam::${AWS::AccountId}:user/${KeyAdmin}
          Action:
          - kms:Create*
          - kms:Describe*
          - kms:Enable*
          - kms:List*
          - kms:Put*
          - kms:Update*
          - kms:Revoke*
          - kms:Disable*
          - kms:Get*
          - kms:Delete*
          - kms:ScheduleKeyDeletion
          - kms:CancelKeyDeletion
          Resource: '*'
        - Sid: Allow use of the key
          Effect: Allow
          Principal:
            AWS: !Sub arn:aws:iam::${AWS::AccountId}:user/${KeyUser}
          Action:
          - kms:DescribeKey
          - kms:Encrypt
          - kms:Decrypt
          - kms:ReEncrypt*
          - kms:GenerateDataKey
          - kms:GenerateDataKeyWithoutPlaintext
          Resource: '*'

The important thing in above snippet is the KeyPolicy. KMS requires a Key Administrator and Key User. As a best practice your Key Administrator and Key User should be 2 separate user in your Organisation. We are allowing all permissions to the root users.

So if your key Administrator leaves the organisation, the root user will be able to delete this key. As you can see **KeyAdmin **can manage the key but not use it and KeyUser can only use the key. ${KeyAdmin} and **${KeyUser} **are parameters in the SAM template.

You would be asked to provide values for these parameters during SAM Deploy.
