Cloud’s high availability myth

Public Cloud services are normally located in Telco grade collocation, best near public exchange points and supplied with high bandwidth connectivity. It should help for resiliency and high-availability, if the cloud operator chose the right design for his network and keeps track of routing and security issues. We found some locations to be not sufficient, though. So always have a deep look at Telco and ISP technology and inspect their high-availability concept.

Furthermore, you have to be sure your location is “always on” from where You have got access the internet: If you don’t have any connectivity to the internet, you won’t be able to connect to your data in the cloud. This may happen to yourself and all employees of your company at same time by simple wire cut. Just imagine: All of the company’s employees can’t access their data because it’s located in the cloud: A nightmare!

There are only two ways to avoid this:

  1. Either you keep your data on your own premises (which is a private cloud in fact), or
  2. Be sure to be dual homed (which connects you to two Internet Service Providers at same time).

If you choose to be dual homed be sure that you use 2 separate ISPs and be sure as well to use two different transport media, otherwise a wire cut by a digger would put you out of service again!

Best is some combination of two connectivity inlets of opposite direction to your building. If all this is not possible use a wired connection (Fiber or DSL) and a mobile backup. But always keep in mind: wireless often has fewer throughputs and much more interference / overbooking than wired connections.

So, before you run into loss of connectivity and unavailability of your data and services: Do a risk analysis for a public cloud scenario first before you run into trouble! Connectivity and availability on ISP side AND on company side is the main point to start the analysis. If either side isn’t highly available, don’t consider public cloud computing for mission critical business data!

We have pointed out some more details about dual homing here (in German language).

Interactive Cloud OS on OpenStack Icehouse

Finally, we are up and running our new Cloud OS with OpenStack Icehouse version.

We have the system running in our lab – so far everything looks fine what we tested.
We have it installing from a TFTP server – so this is the crucial bottleneck for a smooth installation. We will have it as an installation from ISO file (CD, DVD etc.) next week.

Since tomorrow’s Thursday is a holiday in Germany, the development members are off for a long weekend.

But we are happy to finally announce our new version for next week. Should be around Tuesday. So please come back next week and download the new version.
As soon as we have it online, we will have an announcement at all contacts.

Some thoughts on the wording of “OS” or “Operating system”

As you may have seen on several websites, there are various vendors playing around with the term “OS”.

In fact, “OS” in IT language stands for the acronym “Operating System”. An OS facilitates all peripheral and internal devices of a computer by handling, delivering and managing their functions and data.

Currently, HP is advertizing their new HP Cloud OS. But after we take a closer look at the Software, we find that it is based on Ubuntu, which is actually an Linux operating system. So, HP has really only designed a new graphical user interface (GUI) with some add-on tools to the OpenStack toolset. But this is not an OS, because it still needs an OS below to communicate with the computer.

It is very difficult for users to find out, what a system really does and what “cloud” is all about. And it seems to me that in the cloud area people tend to mix up with the definitions of devices and software. But this will just lead us to a total confusion!

In my humble opinion, this is not very helpful. If we do so, it would lead us to my favorite claim “Cloud is virtually anything”.

But if we make everything so “cloudy”, nobody will know what a software or project stands for.

To make it very clear, and since we have been asked to do so: Interactive Cloud OS is an Operating System. Yes, we do bundle it with the OpenStack Foundation GUI to give users a simple way to work with their servers and to manage the virtual servers and any services they wish to use.

But of course, if you don’t like the GUI, you are free to use another one with Interactive Cloud OS. There are alternatives to OpenStack… just ask us.

With our OS, you always get the freedom of choice.
