Cloud computing

"The network is the computer" - Sun Microsystems 1984
Thin clients vs. "Thick clients"
"Cloud" first used in internal doc at Compaq

Intel VT-x (2006)
Linux KVM (2006)

GRE (RFC1701, 1994)
VLAN (IEEE 802.1Q, 2003)
VXLAN (RFC7348, 2014)

AWS Elastic Compute Cloud (EC²)

Datacenter As A Service
Compute, Networking, Storage
Consolidate entire corporate infra into "the cloud"

AWS Offering today

Serverless services

Serverless as an AWS concept (No EC² server involved)
"Higher order" compute and storage abstractions
Physical server → Virtual server → Container → AWS Lambda FaaS/PaaS
Disk → File → DB server → Serverless DB

Buzzword overload

"Cloud" is used all over the place to signify wildly different concepts.

Cloud storage (e.g. Dropbox, Apple iCloud)
Cloud providers (e.g. AWS, Google Cloud Platform, Microsoft Azure)
Cloud native (SW dev methodology and tech stack)
Cloud: Public vs. Private vs. Hybrid
