If you read the announcement there's a fair amount of marketing terms and buzz words in there. I'm not a real buzzwordy kinda guy so here is in real words what it is and why Isaac Rocks....
It’s really the next level in network management, integrated with social media such as Twitter, Facebook, Linkedin and Salesforce.com Chatter (which we use all the time internally). If like me you are never really away from work, having information on the network available in the same tools I’m normally using anyway makes it less intrusive. Plus it lets me deal with issues easily in a language that makes sense to me.
10. it integrates the megatrends around mobile, virtual, and social media
9. it allows users to build their own custom language to manage a network
8. it lets me manage a network from any mobile device.
7. it gives me an instant view into how the network is performing from my Android phone
6. my boss can generate real time stats to get answers to “If we decide to do remote training in Mexico, will the WAN support it” without asking the network engineers
5. it gives me a reason to spend half of my time on facebook and twitter without getting in trouble
4. when i'm having a nice dinner with family and friends and get called, i can fix network issues without getting in trouble
3. it lets me build simple commands to do complex things, like "#ratelimit rcasselb 1M"
2. it makes me feel like part of the under 30 crowd by being "hip and social" which helps offset my thinning hair and thickening midsection :)
but the biggest reason Isaac rocks is I get all of the above plus a ton of other cool things I haven't even really thought about yet.
