The view from the cloud

I am at 30,000 ft going about 200 miles per hour and I look out my window and sIMG_0998ee this.

Many of you have seen clouds before from both above and below, but have you thought about those opposing views when it comes to the IT version of the cloud?

From the ground a solid cloud cover can look flat with few ripples and honestly looks a lot like a blanket be it white, grey or black but it can block out the sun and bring trouble. From above the cloud deck the clouds look different even storm clouds seem thin and light like wispy mountains of marshmallow fluff. Ok maybe there is some poetic license taken there but you get the drift. From above the clouds have peaks and wisps. The gaps between the clouds are more visible because the contrasting color of the ground, sometimes the ground isn’t even visible at all.  When traveling through the clouds on the way to cruising altitude there is typically turbulence as you hit the air pockets and temperature differences that help clouds form in the first place.

Network Television mirrors IT Technology Cycles

There were 2 maybe 3 Golden ages of network television. The first was the initial couple of years that TV existed with shows like the Honeymooners and I love Lucy. The second came in the 70’s – 80’s with shows like the Love Boat, Knight Rider, and the A-Team (plus sweet cartoons like GI-Joe, Transformers, and Thunder Cats). I digress; the third Golden Age was 1989 – 2000 with shows like Seinfeld and Friends netting the networks loads of money. The thing that broke up the golden ages were disruptive technologies. While I wasn’t alive for the first golden age I certainly saw the episodes in re-runs and I saw the second golden age end because of cable networks and the third one come to an end because of better programming on those same cable networks.

Would you like to Swing on a Cloud?

It’s funny how conversations and new environments can stoke creative juices to make more posts. I recently was involved in talking about IT transformation and cloud. During the conversation the customer who was a solutions architect said that their mission was to make “cloud happen”. I laughed and expressed my sympathies it wasn’t my first time hearing this statement. It takes more than just words to transform a business from a corporate datacenter to a Software Defined Cloud Juggernaut. That’s surprising I know, there are some C level folks thinking but I just enter my AMEX number into Amazon and I get cloud.

While that’s true, the reality is to be transformative means you have to understand what it is you are getting into, and more importantly, WHY? Cloud is an awful term used to describe an architecture. I have written before about the types of “cloud” but how do you manage it once you get there. What is it that you will use cloud for? Is it going to be for application development? Rapid deployment and easily built and torn down architectures? How do you utilize the hardware that is already a sunk cost, and how do you plan for the future procurements?

That’s a lot of questions which lead me to ask, how do you plan for your organization to consume cloud? Do you want business units to be able to “self-provision” or do you plan to have your IT department manage requests for provisioning of IT resources? The idea of having a third party managing the requests is also an option though it presents its own unique challenges and questions, of outsourcing the labor as well as your corporate data.

Let’s say for a moment that architecture is settled either via a reference architecture or a public cloud services provider. There are still policy questions that need to be asked, such as: Who is authorized to provision more resources? What tier of service is this individual or group of individuals allowed to request? Is there business unit or line or business chargeback for consumption? What is and is not allowed to be placed in the cloud environment? The last question bring about the issue of security and what policies will be put in place to ensure data in the cloud is protected, safe, and removable. (If your proprietary data gets stuck in a cloud providers data center with no way to retrieve or secure it, is it really yours?)

Not all of these questions are easily answered and they require multiple pieces to make the puzzle whole.

Provisioning of storage can be done with multiple tools, ViPR which I have mentioned before is built to work with VMware Cloud Automation Center, OpenStack, and Oracle. Through these tie ins multi-tenant, multi-vendor solutions can be quickly deployed and automation tools like Razor and Puppet can help to ensure work flow success.

Products like Afore can ensure data encryption occurs across multi-tenant environments. The slick piece here is it’s multi-keyed, which means each tenant environment is encrypted with unique keys, and those keys can be maintained in corporate owned LDAP or RSA Data Protection Manager. So even if the data sits on a public cloud the key is maintain and managed within the corporate security framework. Making the data useless to any external persons with malicious intent.

Backup and recovery solutions such as Data Domain, and Recover Point can ensure data availability and recovery. When used in combination with VMware SRM point in time regeneration not dependent on replication time can quickly improve RTO.

As always there is so much more to go into with each of these products. As I dive deeper I will share more and try to pass my lessons learned along.
