Leading items and editorials
Gartner: dump IIS. The analysts have released a new set of
proclamations relating to Linux and free software. Analyst opinions
should always be taken with a grain of salt (if not an entire shaker
of salt); they do not always reveal a deep understanding of how free
software works. Nonetheless, they are a good indicator of how a
certain segment of the world views free software.
The Gartner Group is one of those analyst operations that has shown,
over time, an inability to "get" what makes Linux what it is. The
Group's opinions have generally been hostile. So [38]the latest words
of wisdom from Gartner are doubly interesting when they state:
Gartner recommends that businesses hit by both Code Red and Nimda
immediately investigate alternatives to IIS, including moving Web
applications to Web server software from other vendors such as
iPlanet and Apache. Although those Web servers have required some
security patches, they have much better security records than IIS
and are not under active attack by the vast number of virus and
worm writers.
Apache, of course, is not a "vendor," but we'll let that pass. It's a
slow process, but the corporate world is beginning to figure out that
free software offers some real security advantages.
It is important, too, that web servers are the subject of this
discussion. Some have claimed that Linux is free of email viruses only
because, as an obscure (on the desktop) platform, it is not an
interesting target for virus authors. But Apache is the dominant web
server platform; anybody wishing to attack large numbers of systems
via a web server would look at Apache first. The "obscure and
uninteresting" argument will not wash here.
D.H. Brown's enterprise functionality study. A much more detailed
proclamation can be found in the "2001 Linux Function Review" recently
[39]announced by D.H. Brown Associates. The full report is available
from [40]the D.H. Brown site, but only for those with $1500 to hand
over. Those willing to register can get an "executive summary" in PDF
format for free.
The report looks at several Linux distributions and reviews their
functionality in a number of areas. The boiled-down rankings, from
best to worst, are:
* SuSE Linux 7.2, "good."
* Red Hat Linux 7.1, "good."
* Caldera OpenLinux 3.1, "above average."
* Turbolinux Server 6.5, "above average."
* Debian GNU/Linux 2.2r3, "above average."
All but Debian beat the "weakest Unix" (UnixWare 7.1.1), but none
achieved the "very good" rating of the stronger Unix systems. D.H.
Brown's reasoning is worth a look; it provides a sort of shopping list
of features that one set of customers, at least, would like to see.
The ranking between the distributions is, to a great extent, driven by
how current they are. Distributions shipping a 2.4 kernel came out
ahead of those still shipping 2.2 (Turbolinux and Debian). Beyond
that, D.H. Brown looked mostly at the additional features built in by
each distributor.
Red Hat wins in the "scalability" category, seemingly because of its
published SPECWeb results. SuSE got a lower rating because it lacks
those results, and "a lack of support for key third-party load
balancing software options." Caldera was penalized for not having a
shipping 64-bit distribution. D.H. Brown remains unsatisfied, however,
with Linux scalability:
...no Linux distribution yet provides scalability functions that
are competitive with RISC-based Unix systems. The largest Unix
systems can support up to 256 GB of main memory and 128 CPU's, far
beyond Linux's practical limitation of eight processors.
Among kernel developers (and others), the question of whether Linux
should ever scale to that many processors remains highly
controversial. Those wanting support of hundreds or thousands of
processors in an SMP mode are likely to be disappointed with the
mainstream Linux kernel; making a kernel work in that environment
carries a number of performance and maintainability costs.
SuSE, instead, wins the "Reliability, Availability, and
Serviceability" (RAS) category. D.H. Brown liked the inclusion of
ReiserFS, the S/390 partition support, and logical volume manager
(LVM) support. But, says D.H. Brown, "True High Availability
clustering options for Linux remain in their infancy." Also:
...leading Unix systems have added features for planned downtime
reductions, such as live operating system upgrades and kernel
hot-patching, which are not available in Linux.
"Kernel hot-patching" in Linux may be problematic, but the comment on
live upgrades shows an ignorance of the upgrade capabilities provided
by a number of distributions, led by Debian's apt system.
SuSE was also declared the leader in the "system management" category,
due to the inclusion of LVM and its installation and administration
tools. No distribution's administration tools were considered to be
all that great, however. There was also an interesting comment:
While ease of use has long been a point of differentiation between
the various Linux distributions, most of the studied vendors have
focused on easing installation and desktop usability, rather than
enterprise systems management. All of the studied distributions
provide strong tools for software installation and management,
based on either the RPM package manager or the Debian packaging
system, but none provide advanced event management capabilities,
which are critical for administrators who must monitor a large
number of systems.
Given that a number of distributors have targeted the large enterprise
market, they may wish to think about improving things in this area.
Red Hat was declared to be the best for Internet and web application
services, mostly for its support of proprietary, third-party
platforms. Caldera's broad protocol support was also called out,
however. All distributions were criticized for their lack of support
for Java2 Enterprise Edition servers. The last category was "directory
and security services," though security does not appear to enter much
into their evaluations. SuSE came out on top as a result of its
inclusion of the latest Samba
Overall:
Based on the results of this latest functional evaluation, DHBA
believes that the leading Linux distributions are now quite capable
of serving as general-purpose operating systems for a broad range
of departmental and workgroup applications.
The study is interesting as a comparison of the distributions, and as
an expression of a certain type of shopping list. It remains, however,
a shopping list. In its comparison of distributions, against each
other and against proprietary Unix, it looks only at which features
can be checked off for each. Features are important, but the drive to
complete feature lists leads to bloated, immature software releases.
A company looking at adopting Linux would be well advised to look
beyond the feature comparison. After all, it is not hard to add a
journaling filesystem to a distribution that lacks one. The real life
and value of a distribution can be found in the openness of its
development process, its approach to security, the strength of its
user community, and the integration of the distribution as a whole.
D.H. Brown has provided an interesting study, but it missed much that
is important.
A quick Sklyarov update. Current events in the world have turned eyes
elsewhere, but Dmitry Sklyarov remains under indictment. Here's [41]a
quick update from the EFF on what's up. Dmitry has a new lawyer, John
Keker, the "[42]Lawyer Lawyers Would Hire If They Got Busted" Among
other things, Mr. Keker handled the prosecution of Oliver North in the
Iran-Contra scandal. The next hearing will happen on November 26.
