The Road to PaaS. What’s Post-IaaS – Network thoughts

Recently, I wrote an article on PaaS for IT BusinessEdge entitled the road PaaS, understanding your post IaaS options.  Here’s an excerpt.

The Road to PaaS

PaaS is an enticing proposition that has generated a lot of market buzz.

But PaaS forces tradeoffs and it shouldn’t be seen as a one-size-fits-all proposition.

To understand, I like to draw the distinction between what I call “Silicon Valley PaaS” and “Enterprise PaaS.” The majority of the discussion in the market today revolves around the Silicon Valley PaaS pattern, which is a truly abstracted “black box” approach to software platforms.

This form of PaaS exposes a set of standardized services to which you write your applications, completely sheltering developers from the underlying complexity below the PaaS abstraction.

It makes a lot of sense for brand-apps built with modern frameworks like Python and Ruby in greenfield development environments that are highly standardized.

The basic premise of the post is that PaaS for an enterprise is VERY different from PaaS for a Silicon Valley start up. And nowhere is it more  different than in the network requirements.

The PaaS customer is a developer who will code an application, use the underlying services offered by the PaaS stack, such a database, storage, queueing, etc.  The developer deploys the code, selects a few options and code is live.

So what’s going on with the network? Well, the PaaS layer will need to auto-scale, fail-over and deliver performance at some level. It may need it’s own domain as well. That PaaS layer will need to talk to underlying network services such as firewalls, switches, etc.  That PaaS really needs access to infrastructure models that deliver network containers to whatever PaaS abstraction the PaaS layer has.

Hard enough to do when all the containers are the same, as it would be in a Silicon Valley PaaS offering.

It doesn’t work with the existing enterprise platforms.  This is a big opportunity for innovation

6 Battlefields Are Disrupting the Cloud Value Chain

By Wouter Belmans and Uwe Lambrette, Directors, Cisco Internet Business Solutions Group

As cloud computing matures and hype becomes reality, uptake among small and medium-sized businesses (SMBs) and large enterprises is increasing. And although the cloud is still in its infancy, the Cisco Internet Business Solutions Group (IBSG) believes it is an appropriate time to ask: “How is the cloud value chain taking shape, and where are the battlefields I need to be concerned about?”

Cisco IBSG has found that major disruptions are taking place on six battlefields across the value chain:

Are Sunny Days Possible in the Cloud?

Yes, but only if there is Trust…

Do you remember not too long ago hopping into your car, driving, across town (when gas was $1- something) to your local retail store and searching the computer department to purchase a cereal box that contained between 2- 8 3.5” (or are you “wise” enough to remember 5.25” floppy) disks?  The disk contained software that would entertain us, make us more productive and educate.  If you don’t remember that, how about going to the record store and perusing the aisles for hours reading the CD boxes that were twice as big as the CD.

Well those days seem long past; and inserting a disk in anything these days….well, seems a bit ancient.

Cloud

We’re now spoiled with the conveniences of iTunes, Salesforce.com, Facebook, Youtube, Yahoo Mail, etc..  In addition, we’re all too familiar with the seemingly millions of applications that run on a myriad of mobile appliances.  None of these programs run on our PC’s hard drive.  They’re browser based applications that are essentially utility services which we share with thousands of users.

So, I began to ponder the question, “What’s the big deal about the Cloud in Manufacturing and Enterprise?”  Read More »

Conversations about Cloud – “What is Self-Service IT?”

Every once in a while (here, here), I have the same conversation enough times with customers that I find it useful to bring it to the blog community. Last week at VMworld 2011, I had the opportunity to spend quite a bit of time speaking with customers and partners about Intelligent Automation and what it means for IT to deliver self-service capabilities to their customers (internal, contractors, etc.). During the conversations, a number of questions came up over and over again: Read More »

Talkin’ Tech: Cloud Computing

Defining key terms for understanding the basics of this emerging technology

Cloud computing continues to be a hot trend in technology and is a great option for budget-minded and resource-constrained small businesses. Cloud-based services offer a more cost-effective solution for accessing applications and hardware on demand and provide small businesses with greater flexibility. In fact, many smaller companies are using cloud services without realizing it. And therein lies the challenge—there’s a general lack of understanding when it comes to cloud computing.

In this installment of our Talkin’ Tech series, we define key terms to help you understand the basics of cloud computing. If there’s a term we didn’t include that you’d like defined, please let us know!
