I have a deep respect for the Netflix team and @adrianco's leadership. <br /><br />Re-read the post again and I'll think you'll see http://www.activestate.com/blog/2012/12/what-i-really-didnt-want-christmas-another-aws-outageAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3153693.post-34242898725636181792012-12-29T20:54:39.300-05:002012-12-29T20:54:39.300-05:00Atleast , you are honest about it.

Said another way, your formula seems to say that the likelihood of the cars starting has nothing to do with the weather outside (that the likelihood of any one car starting is a constant).<br /> <br />I disagree with this position.

This technology allows you to remove the testing constraints inferred while leveraging the VM/Cloud infrastructure. Furthermore, application behavior virtualization can be adopted at cost structure well below traditional harware/os virtualization cost structures. <br /><br />Here is a resource from Parasoft: <br />http://www.parasoft.com/jsp/products/virtualize.jspUnknownhttps://www.blogger.com/profile/10821718768455603671noreply@blogger.comtag:blogger.com,1999:blog-3153693.post-52039293790762746272011-04-06T07:46:11.153-05:002011-04-06T07:46:11.153-05:00I am not sure that intimidated would be the best d...I am not sure that intimidated would be the best descriptive word. I think Enterprise Architects are cautious when it comes to the cloud for a lot of reasons. While I agree with your first premise that most EA leadership has a strong understanding of business domain knowledge and application architecture, most also have at least a fundamental understanding of hardware architectures as well. In every EA career, we have been presented with a scalability question, DR scenarios, virtualization questions, etc. If you do not have at least a fundamental grasp of hardware architecture, then you open yourself up to a lot of nasty surprises.<br /><br />I think the reason that EA leadership is cautious when it comes to the cloud is that they have to look at a lot of aspects including many that you mention in your original post. However, there are also a lot of non-technical aspects that have to be taken into account. If the site goes down for any reason, what is the legal implications to all parties. How much control does the company retain over emergency hardware updates like OS service patches. What are the limitations of supported software and releases. Most Cloud sites are virtualized servers which also have implications on architecture and production service level agreements. If someone hacks into the database and downloads personal information or corrupts data, what are the legal implications there. If it is an internal cloud owned an operated by the company itself, what are the cost justifications. Unfortunately, I do not think EA Leadership is intimidated by the cloud technologically, I think it is the business and legal ramifications of cloud computing that they are still trying to work out in a lot of cases.Blakehttps://www.blogger.com/profile/15419862454959761213noreply@blogger.comtag:blogger.com,1999:blog-3153693.post-82389175957150603212011-03-18T11:48:08.085-05:002011-03-18T11:48:08.085-05:00Our hope is to do more thorough pre-production tes...Our hope is to do more thorough pre-production testing in test labs. We'd love it if those labs were more versatile than what we currently see at many of our customers. Often, it remains difficult for the labs to keep up with the changes to the software packages. In addition, most of them don't have adequate hardware or vm/cloud access. They often end up only testing some of the edge cases. We're big fans of 'service virtualization' from companies like Parasoft and love to see those tools be used on an agile infrastructure (dynamic provisioning).jeffhttps://www.blogger.com/profile/16751830353772022191noreply@blogger.comtag:blogger.com,1999:blog-3153693.post-86415006073800772202011-03-17T13:14:31.362-05:002011-03-17T13:14:31.362-05:00Let's see if I understand your point - Applica...Let's see if I understand your point - Application performance is hard and getting harder, but test labs are too expensive and aren't given enough time to test properly anyway.

Plus there’s a growing body of research coming out of MIT, Gartner, MISQE, and elsewhere that indicates organizations that do EA perform better.

It had been tried a couple times before this attempt, but luckily the current PTB realized that governance was the reason it failed before, and a big emphasis is being placed on that this go round. I am being given a great deal for professional freedom and latitude in leading and advancing the SOA adoption and am stressing the business first approach and alignment of IT Business domains with the Lines of Business of our company. Of course this is jsut the tip of the iceberg, but it is a crucial step in adopting the new way of thinking that is SOA.Anonymousnoreply@blogger.com
