What about security?

Access denied if not authenticated as administrators

• Intake millions of events per

second

• Easy processing on continuous

streams of data

• Correlate streaming with reference

data

• Guaranteed events delivery

• Elasticity of the cloud for scale up

or scale down

• Low startup costs
