OpenStack

So everyone from Red Hat to HP, to Amazon, etc. are creating OpenStack certifications.

Which ones are best, and is there much of an ROI on getting OpenStack certs?

The RedHat OpenStack certifications have the advantage of credit towards RHCA. Certainly if you already have RHCE, this is a good path to choose. For the others I suspect a similar situation, where if you are already in their environment, then adding their OpenStack certifications makes sense.

But this is an area that at the moment isn't very certification focussed. Mostly employers are looking for experience plus whatever basket of technologies they are also using eg OpenStack + AWS or OpenStack + RedHat + VMware or OpenStack + Azure or whatever.

OpenStack is largely the same across the board, which is the interesting thing. All that's changed between the OpenStacks I've looked at is the GUI for the OS that connected it. While everything else it seems is unchanged.

I don't have experience but I've heard OpenStack is just starting to penetrate but it's predicted to get huge. It might be a great time to jump in on it while a lot of others are focusing on AWS and Azure.

I've joined the OpenStack foundation, and 70% of companies (9 out of 10 are taking clouds this coming year, with 19 out of 20 will be cloud by 2017) going cloud are doing OpenStack.

Red Hat OpenStack, SUSE OpenStack, UbuntuOpenStack, as well as OracleOpenStack, etc. are leading the cloud industry arguably.

Azure is at 20% of the cloud industry with 70% of it being OpenStack, and in current trends Azure is losing more foothold, to the point Azure is expected to only be less than 10% of the Cloud Industry in IT. So yeah, OpenStack will be more than worth learning and certifying in.

From my own discoveries, CISCO, Juniper, and even Dell Routers and Switches can be completely virtualized and interfaced with OpenStack. Meaning at one central location in your companies private cloud via OpenStack you can manage everything from Servers, to routers, to switches, to ASAs, to all functions they provide anywhere where access to the cloud exists with appropriate permissions. Including application development, etc.

OpenStack has its place, but that's 3rd place at best. Rackspace is focusing on providing support for Azure and AWS, and less on selling their own OpenStack platform. HP exited the cloud market - theirs ran on OpenStack - and is throwing support behind Azure. VMWare and Google are involved with OpenStack, but that seems to be to make sure their stuff works with OpenStack - not necessarily to run OpenStack.

The real problem is running it at scale. AWS has spent billions on their datacenters and continues to spend 1-2 billion dollars per quarter to maintain and expand that capacity. They have several times the capacity of any other provider, and only a few companies could afford to build enough capacity to compete. Whether they want to spend it or not is another story, see HP. Microsoft appears to be the only other company willing and able to take on AWS.

OpenStack is a solution for a local, private cloud, but you still have to build and maintain a datacenter. Something you cannot do as cheap and as well as a public cloud provider.

Or you could lease rackspace. AWS is definitely the most popular in my experience. Azure is emerging while OpenStack is lying there waiting to be woken.

How about Google Cloud?

I'm starting to prepare for my MIRANTIS openstack certification. Does anyone have got materials in term of exam questions?
