Amazon Elastic Compute Cloud (Amazon EC2) → web service that provides resizable compute capacity in the cloud

• designed to make web-scale cloud computing easier
• gives complete control of computing resources
• reduces time to obtain + boot new server instances → quick scaling up or down
• pay only for capacity used

launch instance

amazon machine image → AMI

• provides info needed to launch instance (virtual server in cloud)
• template for root volume → ex. OS, application server
• launch permissions → control which AWS accounts can use AMI to launch instances
• block device mapping → specifies volumes to attach to instance on launch

instance type

• varying combinations of CPU, memory, storage, and networking capacity
• t3.micro instance type has 2 virtual CPUs and 1 GiB of memory

key-pair login

• create a key pair, specify the name of the key pair when you launch the instance, and provide the private key when you connect to the instance

network

• specify which VPC you want to launch instance inside of
• can use multiple networks → ex. dev, test, prod
