agora con gmbh. we do it consulting, focusing on
strategy consulting, infrastructure and
security. we help organisations to build and maintain
their information technology in a competitive and stable way.
our clients vary from small to big, from telecommunication to
we work with unix, bsd, linux
macos, and the people at noyb.eu ;-)
we love open source software.

we create custom tailored systems by connecting open source
components and make them run smoothly and user-friendly.
automation as general approach - whatever is
presumably done more than once needs automation. we prepare
the project to run automatically on multiple
user acceptance test runway,
failover runway and
teach runway (almost...).
we treat documentation as first class citizen, i.e.
documentation defects are equal important as source
code or design defects. we work on our solutions to be
simple (easy to operate, simple to use),
quick (low response times/high throughout) and
we help our clients to identify and select business areas,
where technology investments support their strategy.
on top of technology we've got industry knowledge in
telecommunication, utilities and financial services. we
appreciate learning from our clients. our song goes like this:
a wise technology selection will sustain the added value / open
industry standards do prevent vendor locks / whatever bad
happens in the early stage / increases the costs running and

design, implementation and hand-over to operations of
infrastructure service. to be more specific, we call
infrastructure the collection of hardware, network and system
services on the layers below business applications. that
include time, mail, file services, databases or security
services. on unix, bsd and linux. service areas: build
(data center set-up or expansion) and optimize (e.g. stateful
firewalls with high throughput: replacement of proprietary
network components with commodity hardware). you can find a

monitoring and performance monitoring.
the times they are a-changin'. while a decade ago monitoring
was like crossing a dessert with a glass of expensive water,
that situation has improved a lot. over the last years several
devops manufactories have released great open source modules
for working with metrics in an high performance environment.
identity and access management.
we've contributed to several large identity and access
management projects, many of them based on oracle solutions or
on solutions oracle has acquired. solution architecture and
security design. an increasing number of highly integrated
components makes you focus on automation in all kind of

i/o and network, over database systems to full stack web
applications. on unix/linux/bsd.
