Choose Cattle Over Pets
• Pets needs care and feeding
– Name the VM
– Tune and groom regularly
– Feed pets with good food and supplements
– Take pets to the vet when they are sick
• Cattle are disposable
– Cloud instances are not unique
– Tune and groom apps not the cattle
– Replace when necessary
– Shoot the cattle when it is sick
