An interesting addition to my yesterday post about technological options for cloud PLM. I was reading Amazon’s announcement that came earlier this month – Amazon separates servers from IP addresses. Navigate to the ZDnet UK Blog article “Amazon Separates Servers From IP Addresses to read more. Here is how this feature explained in Amazon blog:
Today we are adding additional flexibility to EC2 instances running in the Virtual Private Cloud. First, we are teasing apart the IP addresses (and important attributes associated with them) from the EC2 instances and calling the resulting entity an ENI, or Elastic Network Interface. Second, we are giving you the ability to create additional ENIs, and to attach a second ENI to an instance (again, this is within the VPC).
On the picture below you can see how Amazon explains the topology of EIN.
There are two CAD / PLM vendors officially announced their support for cloud – Autodesk and Dassault. Nexus 360 PLM is a cloud PLM coming from Autodesk later this year. Dassault ENOVIA is a flagship product sold by Dassault. Another PLM company claims their support cloud is Aras Corp. I haven’t heard any specific cloud plans from Siemens PLM and PTC. If you’re in discussion with your CAD / PLM vendor these days, you better check if product cloud configuration supports EIN.
What is my conclusion? Even the article is a bit on a technical side, I found it quite important. Cloud is moving towards having more and more “enterprise features”. This is a reaction of cloud providers on the coming demand from enterprise IT to accept cloud usage. The critical question that wasn’t answered was about the cost. Cloud attractiveness is dependent on cost structure. Cloud providers will have to charge an additional fee for enterprise features. Will it be still attractive for company IT? A big question. The architecture of cloud systems is in a very early beginning phase. You better check it carefully with your vendors and/or partner. Just my thoughts…
