features:
Download this improved version from the regular download pages, and do not forget to read the documentation!

Today is a big day for us: we are using Globule to host the Web
site of the new version of the Minix operating system!
This is the biggest deployment of Globule to date. So far,
our servers are doing fine, but we expect to be watching the
system control panels for the whole day to be there if anything
goes wrong...
Note: the version we are using for this is the upcoming
version 1.3.1. Being asked to host this site was a great
exercise for us: it forced us to look into the many small
details that make the difference between a cool research
prototype and a real usable product. So, expect version 1.3.1
to be better than any previous release we made!

The Globule team is proud to announce the release of Globule
version 1.3.0. You are most welcome to download it. Among the new features, you will
find:
- A monitoring interface will give you more insight at
what's going on inside your servers.
- Basic support for replicated PHP pages. Note that
databases potentially accessed by the code cannot be
replicated at the moment (read this paper to learn
how we plan to replicate the databases in the future).
- Easier procedure to upgrade Globule versions. Servers
running Globule-1.3.0 and up will also be able to
interoperate even if they do not run the same versions.
- A completely rewritten user
documentation.
- A website where you
can register your server(s), and find
other servers where to host your contents. Based on these
informations, the site will automatically generate
configuration files for you.
This release should be considered Beta quality which will
undergo some more testing and documentation.

In the past months we have been working on the upcoming version
1.3.0. We still have to test it seriously before releasing it,
but here are the brand-new features that you can expect:
- A website where you can register your server(s), and find
other servers where to host your contents. Based on these
informations, the site will automatically generate
configuration files for you.
- A monitoring interface will give you more insight at
what's going on inside your servers.
- Basic support for replicated PHP pages. Note that
databases potentially accessed by the code cannot be
replicated at the moment (read this paper to learn
how we plan to replicate the databases in the future).
- Easier procedure to upgrade Globule versions. Servers
running Globule-1.3.0 and up will also be able to
interoperate even if they do not run the same versions.
- A completely rewritten user documentation. (although it
is not finished yet, you can have a look at the current
draft).

Version 1.1.0 had a few serious bugs, we released version 1.1.1 to fix them.
|
|
16th April 2004:
|
We released version 1.1.0 of Globule,
which contains many important improvements:
- Fault-Tolerance: Each Globule server periodically
checks the availability of the sites holding its
replicas. In case one replica site is down or
misconfigured, it will stop redirecting client
requests to this replica until it has recovered.
- Dynamic adaptation of replication policies:
instead of selecting replication policies once and for
all, Globule automatically selects the best-performing
replication strategy for each document. It periodically
re-evaluates its choices, to account for potential
changes in access patterns.
- Monitoring: Globule now allows administrators to
better monitor the behavior of their system. First,
access logs to all replicas will be transfered back to
the master site. Second, Globule can attach each
delivered document with information on how this request
was treated.
- New replication policy: we added the Alex
replication policy.
- Bug fixes: plenty of them (see the ChangeLog)...

That's it, we believe our prototype is robust enough! The page
you are currently reading has been delivered by Globule
software. We have four replicas: www.globule.org, slave1.globule.org and
slave2.globule.org.
Another page known to be replicated by Globule is Maarten's
home page. Client redirection is currently done via HTTP,
so by looking at the URL in your
browser you will know which replica you are accessing. Hit the
reload button and see what happens! We are almost ready to
publish Globule software...
