High performance Go based microservice for Amazon S3 that zips files on the fly, streaming archives directly to S3 buckets or generating instant browser download links via IIS.
Zipper API Server V2 (Windows IIS) is a fast, lightweight microservice designed for Amazon S3 to stream and archive files directly within cloud storage without downloading them locally or consuming host disk space. Preconfigured with Internet Information Services (IIS) on Windows Server, the instance runs out of the box on HTTP port 80 to allow easy integration with your organization's existing SSL certificates and security policies.
Key Features & Capabilities:
Flexible Delivery: Zip files directly back into an Amazon S3 bucket or stream compressed .zip archives straight to a client browser via secure download links.
High Performance: Concurrent, streaming compression built to handle large datasets and high volume workloads effortlessly.
IIS Integration: Runs on HTTP port 80 out of the box, giving administrators full control to configure custom domain bindings, SSL/TLS certificates, and enterprise security policies.
Zero Local Storage Overhead: Eliminates temporary disk storage requirements by processing Amazon S3 file streams on the fly in memory.

You pay by the hour for the EC2 instance size you run this Windows IIS zipping server on. All 19 options bill on the same usage basis, so pricing scales with the compute capacity you choose. The t2 and t3 families cover general-purpose sizes, from nano and micro up through 2xlarge. The c5 family covers compute-focused sizes, from large up through 9xlarge and bare-metal (metal). Larger instances carry more CPU and memory and cost more per hour. You start or stop instances as needed, and charges follow actual runtime.
Top-of-mind questions for buyers
What does the hourly charge cover, and am I billed when the instance is stopped?
The hourly charge covers the running EC2 instance you launch this Windows IIS zipping server on. Charges follow actual runtime. When you stop the instance, software hourly charges stop too. Underlying AWS storage fees for the stopped instance's disk may still apply separately.
Does the instance size I pick limit how large a zip request I can process?
The hourly price only reflects the compute size you choose. The server streams files from S3 and zips them on the fly, so it does not download files locally or need extra disk for large archives. Larger instances add CPU and memory, which help handle heavier concurrent zipping jobs faster.
How should I choose between the t-family and c5-family instances for billing?
The t2 and t3 families are general-purpose sizes suited to lighter or variable zipping loads. The c5 family is compute-focused, with more CPU per size, for steady heavy jobs. Both bill per hour on the same basis, so match the family to your workload and pay for the runtime used.
