Are there any known issues/compatibility concerns moving hosted domains, websites (mainly CMS systems Fatwire, Drupal, WordPress) from a Debian OS to either Redhat or Cent OS? This is due to changing data centre providers.
With some effort the migration should work out fine. I'll share some common questions to save you some Googling.
Most visible differences between Debian and Red Hat to sysadmins:
Service Management: update-rc.d on Debian becomes chkconfig on Red Hat. At least they'll unify on systemctl with System D eventually.
Apache configuration: a2ensite and /etc/apache2/ on Debian becomes /etc/{conf.d,conf.modules.d} on Red Hat
Network Interface Configuration: /etc/network/interfaces on Debian becomes /etc/sysconfig/network-scripts/ on Red Hat
Package Management and Software Installation: see RPM DPKG Rosetta Stone

I did go through some articles about migrating to CentOS but not specifically from Fedora to CentOS. I'd like to know the steps and measures to follow
I don't think there is a migration path from CentOS to Fedora or vise versa. even though both systems share the same codebase CentOS is way older than Fedora. I used to be a distro hopper way back, but I kept the /home directory in a different drive so I could install any distro I wanted and keep my data and configuration files intact. You should consider doing the same.
I've been trying to set up a a local Kubernetes installation on an Ubuntu 16.04 VM by following the setup instructions posted here: http://kubernetes.io/docs/getting-started-guides/kubeadm/
However in section (3/4) when installing a pod network, the following line appears: If you are on another architecture than amd64, you should use the flannel overlay network as described in the multi-platform section.
When you scroll down to the multi-platform section the only other architectures it offers are ARM-based: kubeadm deb packages and binaries are built for amd64, arm and arm64, following the multi-platform proposal.
Does this mean I can't get Kubernetes to work on an Intel-based machine?
amd64 is one of the ways people describe x86-64 processor instruction sets. Usually for linux distributions people tend to call their images amd64 because it came along first. Those images work fine on any modern Intel chip.

Im trying to understand what differences are there between this products. Can someone explain me main differences and what is each one's functionality?
They are the same product. During the lifecycle of Satellite 5, the name was modified to go from Red Hat Network Satellite to Red Hat Satellite. So, if you look for documentation for Satellite 5.5. or below it will be listed under Red Hat Network Satellite (https://access.redhat.com/documentation/en/red-hat-network-satellite/) For 5.6 and later it will be listed as Red Hat Satellite (https://access.redhat.com/documentation/en/red-hat-satellite/)
Red hat network sometimes want to say the internal network of red hat for customers
Red Hat Network (abbreviated to RHN) is a family of systems-management services operated by Red Hat. RHN makes updates, patches, and bug fixes of packages included within Red Hat Linux and Red Hat Enterprise Linux available to subscribers. Other available features include the deployment of custom content to, and the provisioning, configuration, reporting, monitoring of client systems.
Users of these operating systems can then invoke the up2date or yum program to download and install updates from RHN. The updates portion of RHN is akin to other types of automatic system maintenance tools such as Microsoft Update for Microsoft Windows operating systems. The system requires a subscription to allow access to updates. (Red Hat's yum and Advanced Packaging Tool repositories provide free access to updates for Fedora systems.)
On June 18, 2008 Red Hat CEO Jim Whitehurst announced plans for the RHN Satellite software to be open-sourced following the Fedora/RHEL model.[1] Subsequently, project Spacewalk was launched.
I've been searching for vagrant box for RedHat linux for a week ended up to nothing. Possibly because RedHat, especially the Enterprise Linux, is under commercial used rather than open-sourced.
I've been trying to learn my ways around JBoss with a RedHat Enterprise Linux distribution via Vagrant. Is there a box already present or should I result to alternative box then install and configure JBoss almost similar with RHEL?
Indeed RHEL is not distributed, you need to register with Red Hat to get access to their distribution.
You can use another Red Hat based distribution and it will work almost the same.
the most famous are probably centos as well as Oracle Linux.
You can find those boxes on :
vagrant atlas : https://atlas.hashicorp.com/boxes/search?utf8=%E2%9C%93&sort=&provider=&q=centos
http://www.vagrantbox.es/ has a few boxes that match your need
I'm planning to build Linux web development server in virtual machine environment on Windows Virtual PC. As I don't have much experience with installing and configuring Linux web servers, I wanted to ask for some advice:
What Linux distribution do you recommend for such server? I want the virtual server to look like real hosting environment.
Do any pre-configured virtual machines for web development exist out there?
Maybe some instruction and tips on configuring?
My requirements for the server are quite standard: latest versions of Apache, MySQL, PHP, probably Python and Postgre.
Thank you.
UPDATE: OK I think I'll go with Ubuntu Server for this.
You can probably go with Ubuntu. It is easy for a beginner and there is plently of documentation on how to install a LAMP stack and later you can move on to other distros.
If you are looking for pre-configured machines, then you can have a look at VMWare Appliances
For the distribution I would recommend Ubuntu - you can add all the server software you want from their repositories.
For a virtual machine I'd recommend Ubuntu Server Edition JeOS, as that won't have any un-needed software on it.
Debian Lenny - rock solid stability & the most package support
I'm sure you can find some
Use prefork-worker apache, MySQL 5/PHP 5, Postgres 8.4.
There are lots of prebuilt vmware images that you can use. You might also consider looking at something like Amazon EC2 for which there are lots of off the shelf images.
I would also suggest Ubuntu server as a base OS.
Incidentally there are other virtualisation options in case Virtual PC doesn't recognise those prebuilt image formats (I think those formats are more standardised and interoperable these days, but not sure)...e.g. there is vmware, and there is virtualbox.org
Does it need to be in Linux straight away? You can run (Apache et al) XAMPP locally and get it up and running in 5 minutes.
