Project Description

CloudI is an open-source private cloud computing framework for efficient, secure, and internal data processing. CloudI provides scaling for previously unscalable source code with efficient fault-tolerant execution of ATS, C/C++, Erlang/Elixir, Go, Haskell, Java, JavaScript/node.js, OCaml, Perl, PHP, Python, or Ruby services.

The bare essentials for efficient fault-tolerant processing on a cloud!

Release Notes

  • Service configuration option request_timeout_adjustment was modified to use Erlang monotonic time so timeout adjustments are not impacted by any OS time changes (now all CloudI service request timeout handling is using monotonic time)
  • Added CloudI Service API logging_set configuration option log_time_offset to log when the Erlang VM updates its time-offset with the time-offset change logged in nanoseconds (the offset is logged exactly when logging timestamps are changed)
  • configure script now accepts environment variables to set release configuration values: CLOUDI_ARG_NODE_NAME_SHORT, CLOUDI_ARG_NODE_NAME_LONG, CLOUDI_ARG_NODE_COOKIE, CLOUDI_PID_FILE (can be used to avoid manual vm.args modifications)
  • Many deployment changes to make CloudI use robust:
    • The release script is safe for root use (external environment variables are blocked, functionality is locked down, manages a pid file correctly, etc.)
    • Execution now occurs within the logging directory so any crash dump output is put there automatically
  • cloudi_service_null is an Erlang service added to provide a simple way of consuming CloudI service requests (during testing and/or to handle invalid URL service names)
  • cloudi_service_request_rate was added to the CloudI release to provide an easy way of testing max throughput
  • cloudi_service_http_cowboy and cloudi_service_http_elli now use an update_delay argument to apply a change to timeout_async and/or timeout_sync performed with the CloudI Service API services_update
  • Bugs were fixed and other improvements were added (see the ChangeLog for more detail)
