Economist: Unlocking the Cloud

The Economist is now reporting on the cloud. They’ve picked up on the very real concern of vendor lock-in because of proprietary standards. The article focuses on data portability between SaaS apps, but the same issue arises in IaaS (different proprietary virtualization formats, despite what the Open Virtualization Format (OVF) promises), and in PaaS (google app engine extensions to Python which are hard to ignore and lock you into their platform).

Video 1/4: The Challenges of Web 2.0 Security

I did a series of videos in the fall of 2008 about Web 2.o, SOA, entitlements, etc. These were on the Layer 7 home page until recently, when we went through another re-design. The videos still exist on YouTube, but we did nothing to promote them so they haven’t been seen by too many people. I’m going to re-post them here over the next week for posterity.

This is the first time I had done this kind of media. I spent the day down at Media2o in Gastown. Bradley Shende and his crew are real pros, and I really enjoyed the whole experience. But I do have to confess: it’s a lot harder than it looks. I’ve done loads of talks at conferences, web casts, etc, and I honestly went in believing that I would knock it off in one take each and be out in time for lunch.

Was I ever wrong. Even with the aid of a teleprompter, it took hours of video to get these four short pieces. We were all pretty tired by the end of the day. I learned an important lesson here. You just can’t underestimate how a different media will impact how you perform. I can still barely watch these without cringing.

Hopefully I’ll get a chance to do this again. And I’m going to practice a lot more in front of a mirror this time…

NIST Perspective on Cloud Computing

Earlier this month, NIST went public with their perspective on cloud computing. This is important because NIST is a well-respected, public standards organization, and there is still a lot of confusion about what cloud really is (the *-aaS affect).

They released only  a short, two page document and a longer, 72 slide PowerPoint (you can find their main page here). They are offering a broad definition based on essential characteristics, delivery models, and deployment models:

Essential Characteristics:

On-demand self-service

Ubiquitous network access

Location independent resource pooling

Rapid elasticity

Measured Service

Delivery Models:

Cloud Software as a Service (SaaS)

Cloud Platform as a Service (PaaS)

Cloud Infrastructure as a Service (IaaS)

Deployment Models:

Private cloud

Community cloud

Public cloud

Hybrid cloud

There’s not really anything new here, but that’s fine; it’s more important as a validation of the emerging models and ideas from a public standards body. I do like the three pronged approach, acknowleding that cloud is a lot of things but at the same time keeping it simple and concise. Brevity is the soul of great standards.

It’s worth keeping an eye on this effort.




OMG SOA in Healthcare Conference

I’ll be speaking next week at the Object Management Group’s conference on SOA in Healthcare. It’s next week, June 2-4 at the Hyatt Regency in Chicago.

I’ll be presenting a case study of a deployment we did with the University of Chicago Medical Center. I’ve spoken at a few OMG meetings in the past and they are very good. It kind of feels like a return to my roots. I started my career in a medical imaging research group at the University of British Columbia.

Hope to see you in Chicago.

Upcoming Webinar with David Linthicum

Dave and I are co-presenting a webinar this Thursday, May 27th at 10am Pacific/1pm Eastern. The title is Cloud Control: Reducing the Risk for Cloud Deployments.

It’s going to be great to share the stage with Dave, whose work I have followed for a long time and is truly one of the great thought leaders in the SOA and cloud computing space.

Dave is going to introduce the key issues in cloud governance, and I’m going to present some concrete technological solutions that should be the foundation of your cloud governance program.

I hope you can join us. Register here.

Governance in the Cloud White Paper Now Available

We’ve released the first in my series of white papers on cloud governance. This is the high level overview of issues and solutions, titled Steer Safely into the Clouds. You can download it from the Layer 7 website.

I’d love to hear your comments about it.

GigaOm Piece – SOA Governance Determines Success in the Cloud

I just wrote a short article about SOA Governance and its applicability in the cloud for GigaOm. This is a very influential blog and I’m excited to publish with them.
