• Instance families are different combinations of CPU, Memory, Storage and Networking capacity. ^8eb238
• Instance families allow you to choose the appropriate combination of capacity to meet your application’s unique requirements.
• Different instance families are different because of the varying hardware used to give them their unique properties.
• Commonly instance families are called “Instance Types” but an instance type is a combination of size and family.
