Multi-tenancy vs. single-tenancy: multi serving multiple clients at the same time, one resource instance can serve multiple clients, single need to have their own instance of each resources, each resource needs its own instance. Iaas: paas, 2 components, os, windows, linux, mac, software development/any other kind of development environment, appropriate api. Ide integrated development environment: ex: building apps for ios, saas, use software remotely, no need for maintenance etc. for end user. Scalability and reliability: scalability means you can grow when you have higher number of users, reliability means fault tolerance, redundancy supports more hardware in case one of them fails. Security: encryption, hashing, digital signatures, public key infrastructure (pki) Iam (identity and access management) and sso (single sign-on) mechanisms for accessing services and interfaces: need to figure out who did what in case of something wrong, hardened virtual server images, cloud usage monitors.
