Pay-as-you-go pricing
The on-demand delivery via the internet of services with pay-as-you-go pricing characterizes cloud computing.
Services are delivered via the internet.
The on-demand delivery via the internet of services with pay-as-you-go pricing characterizes cloud computing. Services incurred from a cloud services provider are operating expenses, not capital expenses. Capital expenditure (CapEX) is less common with the cloud, in favor of operational expenditure (OpEx). Skills and training for personnel are required to leverage cloud computing.

Create individual IAM users.
You should always create IAM users for individual users, since the root account should never be used for actual work.
Activate Multi-factor Authentication (MFA) on your root account.

Amazon Virtual Private Cloud infrastructure
Protecting the infrastructure that runs all of the services in the AWS Cloud is the responsibility of AWS. Such services include EC2 infrastructure — the hardware compute platform for running EC2 instances and Amazon Virtual Private Cloud — or VPC, which enables customers to provision a logically isolated section of the AWS Cloud to launch their resources. The subnets, security groups, and network access control lists configured in the VPC are the responsibility of the customer.

If you have a new application and you are not sure about future demand, which of the below characteristics of cloud make cloud an ideal place to host it? (Pick 3)
Performance efficiency
High availability
Pay as you go
No single point of failure
No upfront payment
Scalability
Pay as you go
No upfront payment and pay as you go mean that you do not need an initial outlay of capital for resources to build in cloud. Rather, you only need to pay for what you use going forward. These combined with the ability to consume more resources when needed (scalability) mean that cloud is a great way to host applications that have dynamic requirements.
