Dimensions summary
The software itself is free. You pay only the hourly rate for the AWS EC2 instance type you choose to run it on. Each dimension maps to a specific instance type, billed per hour of use. Options span general-purpose (m-series), compute-optimized (c-series), memory-optimized (r- and x-series), and storage-optimized (i-series) families across several generations and sizes. Pricing scales with the instance you select: smaller types like t3.nano cost less per hour, while larger types like c3.2xlarge or x2iedn.xlarge cost more. Match your instance choice to your dataset size and processing needs.
Top-of-mind questions for buyers
You pay the hourly software rate only while the instance runs. Fully stopped instances stop accruing hourly software charges. Stopped instances may still incur underlying AWS storage fees for attached volumes, but the software meter counts running time only.
Each hourly charge covers one running EC2 instance of the type you selected. That instance runs the deployable software image, reading data from your S3 buckets and writing results back to S3. You are billed per instance-hour of runtime, per the instance type chosen.
Each running instance bills separately at its own hourly rate. Running multiple instances multiplies the hourly charge by the count of active instances. Rates differ by instance type, so a mix of types produces different per-hour charges that add together on the same invoice.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.

Usage instructions
Subscribe to Parqify Viewer in AWS Marketplace. Launch an EC2 instance from the Parqify AMI in your target AWS Region. Select an instance type supported by this product. Configure networking: Public deployment: launch in a public subnet with a public IPv4. Private deployment: launch in a private subnet and ensure private connectivity from your client network. Configure the security group: Allow HTTP 80 from your trusted client CIDR. Allow SSH 22 from your trusted admin CIDR. Avoid open access from 0.0.0.0/0 unless required for testing. Configure storage: Parqify Viewer requires root EBS volume of at least 20 GiB (gp3 recommended). Attach an EC2 instance profile (IAM role) with required S3 permissions for viewing your parquet/CSV files. Launch the instance and wait until it reaches running and status checks pass. Retrieve the one-time activation code: In EC2 console, open the instance and go to Actions -> Monitor and troubleshoot -> Get system log. Search for: PARQIFY VIEWER INITIAL ACTIVATION CODE (ONE-TIME): Open the Parqify Viewer UI: Public deployment: http://<public-ip>/ Private deployment: http://<private-ip>/ from a connected path (VPN / Direct Connect / bastion / Session Manager tunnel). On first login, enter the one-time Activation Code, then set a new password when prompted. Login with the newly created password. Fill the S3 path to the files you want to view and press View Parquet/Schema/CSV.
