Re: Why the IBM i *might* not be a good web server

As a side story to that. One time I was running an upgrade of some vendor
software. The system was pegged at 100% for over 12 hours while other people
where still using the system for a portion of that time. While it was
slower, they could still work. Lets see any other server be able to do
that... THAT is why I like this system.

IBM i's very nature and foundation it was built to be
a multi-job/multi-user/multi-DB/multi-etc machine.

Speaking of multi-job architecture, I noticed yesterday that a client was
running about 6,500 active jobs on their 4-core IBM i server including

multiple

instances of Apache; an Admin instance, a Zend instance, a Web Query

Instance,

one for serving RPG CGI, and another for who knows what. The log for the

RPG

CGI instance indicated an average of 6 CGI requests per second average

over a

period of 10 hours. That's not counting requests for static content.

Thousands

of 5250 sessions. Thousands of other types of workloads. I contrast that

with

my 2-core Windows laptop that according to Task Manager is running just 6
applications, 24 processes, and 75 services.

The appeal of running something like Wordpress under IBM i would be that

you

don't have to manage a 2nd physical server. If you bought an IBM i

server in

the last 4 years, you probably have capacity to spare, without adding a

Windows

server. Web technologies offer a future for IBM i. I question whether the
platform would survive if it were relegated to just 5250 and DB

workloads.

One appeal of running native Web workloads under IBM i is the unmatched
integration with legacy systems and data. In the last decade we witnessed

a lot

of new workloads deployed under Windows and Linux for applications like

approval

& routing, document management, business intelligence, dashboards,
reporting, and so forth. During the coming decade I envision those types

of

workloads embedded right into mainline systems. For example, we provide

a

screen for schools to maintain student records. Once a student record is
selected, a link offers a view of student's entire school transcript in

HTML

format. Another link to transform it to XML so it can be forwarded to a

Web

service that makes it available to Colleges anywhere, and another link to
generate a condensed PDF. In the past, user's may have relied on an

external

server and an external interface to generate those types of documents,

but in

the future that function will be embedded into mainline systems.
