Deployment Platform/Deployment

Scenarios

The following list describes common deployment scenarios where Harmonic Distribution might be useful. The final model might be an intermediate variant of them.

Online peers

There is a master server located in the Internet in highly accessible place for any maintaining work. The main task is supporting users that are connected to the server all time.

Possible options for deployment packages are:

  • Attach proper repository and install client sides packages. Client packages need to be preconfigured to connect to the Internet located server.
  • The same but with special XO image that is ready to work right after flashing a XO.

Dedicated online school server

A machine that has Internet connectivity and is intended to serve clients, e.g.,:

  • base software updates,
  • Sugar Network content,
  • collect usage statistics,
  • provide OLPC's XO anti-thief support,
  • backup functionality for client.

Server might be master (the main server) or node (replication of master). For nodes, the synchronization process with master will happen on regular basis using current Internet connection.

Possible options for deployment packages are:

  • Attach proper repository and install preconfigured server sides packages.

Dedicated offline school server

The same server as online one with a difference that it doesn't have Internet connection and needs to be synchronized using sneakernet.

Possible options for deployment packages are:

  • Attach proper repository and install preconfigured server sides packages.

Peer as a school server

The case when one of peers can play a role of either online or offline school server.

Possible options for deployment packages are:

  • Attach proper repository and install client and server sides packages. Client packages need to be preconfigured to connect to the same peer as a server. Server packages need to be preconfigured for serve clients around using existing network interface, i.e., ethernet or wireless ad-hoc.
  • The same but with special XO image that is ready to work right after flashing a XO.

Deployment packages

Repository

It might be either on of Sweets Distribution repositories or a repository derived from Sweets Distribution one and preconfigured.

XO image

Regular XO image created with including packages from proper repository.

Synchronization

Only server need to be synchronized.

Online synchronization

Offline synchronization

The process is based on sneakernet.
