The presentation is about a specific way OERs are packaged and distributed to improve Internet experience in a resource constrained Indian Public Schools. We collected, curated or harvested the already curated OERs as independently installable Docker Images. We run all the Dockerized containers on a single GNU/Linux host machine along with a container, called Portainer, that could manage other containers. The result is a data center in a single TB disk. Such a disk was replicated to make more disks and distributed to schools. When we run a PC using such a disk, the machine transforms into a data center. One of the container is a feature rich platform with a workspace for collaborative learning, called Gstudio. GStudio has features for blogging, discussion forums, file sharing, creating a gallery of pictures, videos, creating and delivering online/offline courses, analytics to track the performance. As a result this infrastructure is useful not only as a consumer space but also for producers.

We have so far distributed such disks to more than 500 public schools in four different states of India. One single TB disk could contain: Wikipedia (55GB), KALite website (36GB), all Phet simulations, NROER (300GB), Sugar Desktop (1GB), Ownclowd, Turtle, Snap, Edgy, Software Downloads (20GB) and Gstudio with 40 units of online courses (44GB).

A typical public school in India has a computer lab with about 10 computers, usually connected through a LAN. After converting one of the PCs into a server transformed into a data center, upto 20-30 students could use the available 10 terminals. The Gstudio has a special feature to log more than one student at each terminal, called buddy login. Performance analytics are taken for each student separately, though they were sharing the same terminal.
