This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started). Mostly now the topics are about IoT and SD-WAN.

The Datacenter as a Computer
As computation continues to move into the cloud, the computing platform
of interest no longer resembles a pizza box or a refrigerator, but a
warehouse full of computers. These new large datacenters are quite
different from traditional hosting facilities of earlier times and
cannot be viewed simply as a collection of co-located servers. Large
portions of the hardware and software resources in these facilities must
work in concert to efficiently deliver good levels of Internet service
performance, something that can only be achieved by a holistic approach
to their design and deployment. In other words, we must treat the
datacenter itself as one massive warehouse-scale computer (WSC). We
describe the architecture of WSCs, the main factors influencing their
design, operation, and cost structure, and the characteristics of their
software base. We hope it will be useful to architects and programmers
of today’s WSCs, as well as those of future many-core platforms which
may one day implement the equivalent of today’s WSCs on a single board.
Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use.

When building a DDoS mitigation service it’s incredibly tempting to think that the solution is scrubbing centers or scrubbing servers. I, too, thought that was a good idea in the beginning, but experience has shown that there are serious pitfalls to this approach.
