Relatório da Bloor Research diz que o [GNU/]Linux está pronto para o 
ambiente
corporativo em termos de escalabilidade, disponibilidade,
confiabilidade, segurança, gerencimento e flexibilidade. Há três anos a
mesma empresa afirmava o contrário.

Just three years ago, Bloor Research published a report concluding that
Linux was not ready to support large enterprise applications.

Today Bloor Research North America announces the results of a follow-up
study looking at the Linux of today and its enterprise-readiness. The
report will be published in December costing £350 hard copy, £2900
licence. A pre-publication discount and full details can be found here.

After examining Linux scalability, availability, reliability, security,
manageability, flexibility, as well as server consolidation
characteristics, Bloor Research believes that Linux is now enterprise
ready.

Joe Clabby of Bloor Research North America, and the report's author
commented "Linux now scales well on Intel hardware, and by taking
advantage of failover extensions from Linux distributors and Grid
suppliers, high availability can be achieved. Linux is proven to be
reliable, especially for dedicated applications, and its open source
nature ensures that it is at least as secure as its rivals."
Key Findings

Scalability

At present, Linux scales well vertically to 6-way SMP on Intel hardware.
But, over the next three months, expect to find Linux 2.5 scaling to be
back ported into Linux 2.4 kernel distributions (allowing for 8-way
scaling). The next major revision (Linux 2.6) will provide up to 16-way
scaling in about a year.

IBM can scale Linux on its zSeries mainframe using virtual machine
technology - ideal for server consolidation purposes. Linux scales
extremely well horizontally in distributed "grid" computing
configurations.

Availability

Failover extensions can be found in the base Linux kernel (downloadable
for free), from Linux suppliers such as Red Hat, SuSE, or other United
Linux suppliers, from traditional hardware/software vendors such as Sun
and IBM, and from Grid suppliers.

Reliability

>From experience as well as user feedback, Bloor Research knows that
reliability is dictated by systems hardware as well the operating
environment and related applications that run on that hardware:

Bloor Research's analysis indicates that almost 90% of Linux is
installed on Intel platforms, generally known to be reliable. The Linux
operating environment has also been proven to be reliable - especially
when used to run dedicated applications. When Linux systems have failed,
the failures have largely been caused by incompatible applications
contending for the same system resources; poorly written device drivers;
or limitations in the operating environment (for instance, early
revisions of Linux were not written to exploit multi-processor
environments). One way to avoid this dilemma is to buy "advanced server"
or "enterprise server" pre-tested environments from reputable Linux
suppliers.

Security

When you think "Linux security", think "UNIX security". But, Bloor
Research did find that Linux security and UNIX security are hugely
different in one respect: openness. Because Linux is based on open
source code, a huge community of developers closely scrutinises Linux
code, thus revealing any code-related security issues.

Linux developers can build their own layers of security directly on the
Linux kernel. This is beneficial for enterprises and governments who
want to invest in specialised security development. However, most
business CIO's will want to avoid making source code modifications that
would limit their support options.

Manageability

Although many UNIX-based manageability tools, utilities, and
applications can be used to manage Linux environments :-

Very sophisticated Linux management tools (including workload balancing,
performance/tuning, and other Linux management products) are available
from Grid vendors in the form of distributed resource management tools,
utilities, and applications.

Some vendors with major commitments to systems management (such as CA,
IBM, and Sun) have done UNIX to Linux systems management ports - and
currently offer rich suites of Linux management tools, utilities, and
applications.

Flexibility

To date, Linux has been highly successful in achieving its flexibility
goals - running on small, mobile hardware chipsets such as ARM; various
embedded chipsets; popular but somewhat obscure chipsets such as Saturn,
Hitachi's H8, Amtel AVR, the Motorola 68K family; all the way through
powerful, enterprise server chips such as HP's Alpha, Sun's UltraSparc,
Intel's Pentium, and Itanium series, and IBM's PowerPC series.

Linux offers ISVs the opportunity to write code once - and run that code
on many different platforms.
