How many startups does this put out of business? This keeps happening repeatedly - so let there be no more startups offering missing features of EC2. Go back! Build something else! Amazon has made it clear that you should not build a general cloud offering on top of EC2 - it must be niche, or not an enhancement of their offering, or they will simply do the same thing and kill you.

I Agree. But what's so special about this? Any startup must think about the defendability of its idea. Completing very obvious gaps in the Amazon-offering is surely hardly defendable.

It's not clear whether Auto Scaling can only be based on inputs from CloudWatch, or your own inputs as well. Anyone know? Also, you better trust Amazon to fairly determine when to scale up... more instances == more profit for them.

Unscrupulousness is easier if the other party is complicit: much more profitable to make people want to lower the thresholds before spinning up a new server ("We recommend setting the trigger when your CPU load is 0.1 and disk iops is 10/s") versus the gauche act of the visible rip-off.

"UP with me! up with me into the clouds!

For thy song, Lark, is strong;

Up with me, up with me into the clouds!

Singing, singing,

With clouds and sky about thee ringing,

Lift me, guide me till I find

That spot which seems so to thy mind!"

--William Wordsworth

Amazon shouldn't need to warn people of general good business practices. Anytime someone builds a business around a single entity in this case Amazon WS, they are prone for obsolescence when the entity includes "their" functionality into the core offering.

There are many cloud providers now. Startup should be diversifying their offerings to work with all cloud providers this will give their business the best chance for success.

Check out the marketing language for RightScale:

http://www.rightscale.com/

Their "Key Features": (1) Auto-Scaling, (2) Monitoring & Alerting, (3) Load Balancing. Ouch.

But you're right -- the opportunity to provide unique value is in harnessing EC2 for specific purposes and applications.

Does auto scaling mean my instance will grow in ram/cpu/other resources or i'll be just given more new instances?

Hot-CPU/memory switch would be a little freaky.

It's here, it's simple, and it works..

Usage: xm mem-set

Set the current memory usage for a domain.

Usage: xm vcpu-set

Set the number of active VCPUs for allowed for the domain.
