Cloud Computing and B2B

After a Heavy buzz on Cloud computing with all giants marching towards Cloud computing, I was just thinking on how B2B as a domain go with the "Cloud" :) :)
Can look at different angles.... B2B vendors, B2B users, and B2B service providers

At the outlook... a good prospect for all B2B users... and here is my SWOT analysis :) :)

Strength:

• Software as a service available at the door step!!!
• no investment for hardware
• easy to use
• no maintenance hazzles
• helpful for common man, as the details are abstracted and no need of technical knowledge

Weakness:

• At times data integration cost might be cheaper than investing on cloud .. In this EAI world, there might be chances that services provided by different clouds can be varying..which might lead to invest in different clouds
• If 2 trading partners in different cloud, the Synchronous communication, performance in stress.. to be watched out

Opportunity

• No Hardware investment
• Globalisation, the next avtar of e-commerce.. :)
  

Threat

• Security constraints.. Specifically in B2B world, the sharing the signing, encryption credentials might be a threat
• Response time between message exchange also a thought to be given to.. as the HL7 world...or few of EDI world have a Heavy transactions and requires faster response time
  
• Inter cloud connectivity, communication ...
• Too many clouds
• technical competencies, innovations might go down
• Hardware ppl to watch out !!!!
• Terms and conditions are controlled by cloud owners
