Turn your S3, GCS, Azure, or S3-compatible buckets into a secure SFTP/FTPS/FTP/SCP file server in your own AWS account: self-healing, horizontally scalable, and managed through an authenticated browser admin UI.
DocEvent Simple FTP Server is a self-hosted, multi-protocol secure file server that puts an SFTP, FTPS, FTP, and SCP front end on the object storage you already use: Amazon S3, Google Cloud Storage, Azure Blob/Data Lake/Files, and S3-compatible endpoints. You deploy it into your own AWS account from a CloudFormation template, so your files and credentials never leave your infrastructure.
Multi-protocol access lets partners and legacy systems that speak file-transfer protocols read and write cloud object storage directly, without copying data into a proprietary store. Bring your own storage backends across S3, GCS, Azure, and S3-compatible services.
The product is built to run in production. Deploy 1 to 4 interchangeable instances behind a pool of stable Elastic IPs, managed by an Auto Scaling Group that automatically replaces unhealthy instances. All instances share one configuration and host identity from a single per-deployment S3 bucket that is versioned, KMS-encrypted, public-access-blocked, and TLS-only. Configuration changes are hot-reloaded automatically; certificate changes take effect on restart.
A built-in, browser-based admin UI is the control surface: edit services and users, upload or replace TLS certificates and the SSH host key, view live health and status, and restart the server, with no shell access required. The admin API is authenticated with an operator-set password (Argon2id-hashed, stored in AWS Secrets Manager) and every action is audit-logged.
Secure by default: the server runs as a non-root service user, bootstraps a self-signed certificate on first boot with clear warnings to replace it, and uses a fail-safe startup path that keeps the admin UI reachable even when key material is invalid. Runs on AWS Graviton (arm64) for strong price/performance, with the CloudWatch agent preinstalled. Billing is handled entirely by AWS on an hourly basis, so there is no separate license to manage.

Self-healing and horizontally scalable: 1 to 4 interchangeable instances behind a pool of stable Elastic IPs, with shared, hot-reloaded configuration in a KMS-encrypted S3 bucket.
Authenticated browser admin UI to manage config, users, TLS certificates, health, and restarts, with no shell access required, Argon2id password auth, and full audit logging.
AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
Try this product free for 7 days according to the free trial terms set by the vendor. Usage-based pricing is in effect for usage beyond the free trial terms. Your free trial gets automatically converted to a paid subscription when the trial ends, but may be canceled any time before that.
You pay by the instance-hour for each running server, billed through your AWS account. The ten dimensions are all AWS Graviton (arm64) instance types, so you pick based on size and performance rather than separate feature tiers. The t4g family (micro, small, medium, large) covers lighter workloads. The c6g, c7g, and m6g families (large and xlarge sizes) offer more compute or memory. Every instance type includes the same file-transfer capabilities; only the underlying hardware and hourly rate differ. You can run one to several instances and scale by adjusting the count.
Top-of-mind questions for buyers
What do I actually get for each instance-hour I'm billed?
You get one running Graviton (arm64) server that provides SFTP, FTPS, FTP, and SCP access over your own object storage. The instance type sets the CPU and memory size. All types run the same file-transfer software; you pay per running instance-hour to your AWS account.
Am I charged when an instance is stopped, and how do I scale up?
You pay per running instance-hour, so stopped instances stop accruing software charges. You set the server count from one to eight instances in the CloudFormation stack. Adding instances raises the hourly cost by that many running servers. Underlying AWS storage or IP charges may still apply.
Are there separate charges for data transfer, users, or protocols on top of the hourly rate?
No. The Marketplace pricing meters only running instance-hours. There are no per-user, per-connection, per-protocol, or per-GB software charges. SFTP, FTPS, FTP, and SCP are all included on every instance type. Standard AWS infrastructure fees for storage and networking still apply separately.

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.
Version release notes
Adds support for the t4g.micro instance type, for light workloads and free trials. No configuration changes are required and the software is otherwise unchanged from 0.1.34. Existing deployments update by setting the CloudFormation AmiId parameter to /aws/service/marketplace/prod-alchs747magvm/0.1.35 and cycling instances one at a time (configuration, users, TLS/SSH material, and the Elastic IP pool are all preserved). Multi-protocol SFTP, FTPS, FTP, and SCP access over Amazon S3, GCS, Azure, and S3-compatible storage; self-healing Auto Scaling Group behind a stable Elastic IP pool; authenticated browser admin UI. Runs on AWS Graviton (arm64), Amazon Linux 2023.

Usage instructions
After subscribing, launch the product with the provided CloudFormation template (Launch CloudFormation). Supply your VPC, public subnets, instance count (1-4), and the CIDR ranges allowed to reach the file-transfer ports.
The stack creates a per-deployment, KMS-encrypted S3 bucket (docevent-sfs-<DeploymentId>) that holds all shared state: config.yaml (services + users), tls.crt / tls.key (FTPS), and ssh_host_key (SFTP identity). On first boot the server bootstraps a self-signed TLS certificate and SSH host key into the bucket so the deployment is immediately usable; replace these with your own before production use.
Manage the server through its browser-based admin UI on port 8080. By default the admin port is restricted to 127.0.0.1/32, so reach it via AWS Systems Manager (SSM) port forwarding to an instance. On first access you create the operator password (stored Argon2id-hashed in AWS Secrets Manager). From the admin UI you can edit services and users (config changes hot-reload), upload or replace TLS certificates and the SSH host key (certificate changes require a restart, available from the Status page), and view live health.
File-transfer endpoints: SFTP and FTP on their standard ports, FTPS over TLS, and SCP. Point a DNS name at the deployment's Elastic IP pool (multiple A records) for a stable hostname.
Configure your storage backend (Amazon S3, Google Cloud Storage, Azure Blob/Data Lake/Files, or an S3-compatible endpoint) in config.yaml via the admin UI.
Billing is hourly per running instance, handled by AWS Marketplace. Support: support@docevent.io

Support covers deployment, configuration, and operation of the DocEvent Simple FTP Server, including the admin UI, storage backend setup, and certificate management.
