Lenticularis-S3 is an AWS S3 multiplexer to service multiple server instances at a single access point.
Lenticularis-S3 (Lens3) provides an AWS S3 service at a single access point while using an existing S3 server. An S3 service is usually owned by a single user (unix root), but it may not be acceptable by site's security policy. Lens3 starts multiple S3 servers (backend server instances) one for each user, which confines operations by user's permission.
Lens3 uses MinIO as an S3 object storage server. MinIO is an open-source, commercially supported S3 server. Please refer about MinIO to https://min.io.

Lens3 works as a proxy and a manager of MinIO instances. It launches a MinIO instance on an S3 request, redirects access requests to the instance, and manages the life-time of the instance. This service, called "Lens3-Mux", is started as a systemd service. Lens3 also provides a simple Web-UI for managing bucket pools. A "bucket pool" is a management unit in Lens3 which is associated to each MinIO instance. A Web-UI is used to register S3 buckets to a pool. This service, called "Lens3-Api", is started as a systemd service, too.

Lens3 uses MinIO as a backend S3 server. Lens3 lacks a way to display a credit to MinIO, because it blocks accesses to MinIO's user interfaces. Please refer to https://min.io.
