Pricing Calculator for Amazon Keyspaces (for Apache Cassandra)

This application helps you quickly estimate your monthly costs when using Amazon Keyspaces (for Apache Cassandra). By providing basic workload parameters—such as read/write throughput, data size, and TTL delete rates—you can view an approximate cost breakdown for Provisioned and On-Demand capacity modes.

Features

• Dynamic Cost Estimation: Quickly calculate approximate monthly charges based on read/write throughput, average row size, storage needs, TTL deletes, and more.
• Multi-Region Support: Optionally replicate to up to five AWS Regions and see how your choices affect total cost.
• Provisioned vs. On-Demand: Compare both capacity modes to determine the pricing strategy that best fits your use case.
• Point-in-Time Recovery (PITR) Toggle: Easily include or exclude PITR in your cost estimates.

Prerequisites

• Node.js (optional) – if you are running a local web app or CLI tool that uses JavaScript.
• AWS Account – to reference or verify costs with the official AWS Keyspaces pricing page.
• Web Browser – if you are running this as a static web app.

(Depending on how you deploy or run the calculator, your prerequisites may vary.)

Configuration

Within the app, you can configure the following parameters:

• Primary AWS Region
  Choose the AWS Region where your Keyspaces data primarily resides (e.g., us-east-1, us-east-2, etc.).
• Replicate to AWS Regions (0–5 optional regions)
  Select additional regions for multi-region replication.
• Average Read Requests
  Estimated average read requests per second (per region).
• Average Write Requests
  Estimated average write requests per second (all regions).
• Average Row Size (Bytes)
  Size of each row in bytes (e.g., 1024 for 1 KB).
• Storage (GB)
  Total amount of data stored, in gigabytes.
• Point in Time Recovery
  Enable or disable PITR to see how it affects cost.
• TTL Deletes per Second
  If your application uses TTL (Time to Live) on rows, estimate how many deletions occur each second.
