On demand delivery of IT Services, Pay as you go

Cloud Computing Benefits

the ability to increase workload size within existing infrastructure (hardware, software, etc.) without impacting performance

Speed, Experimentation, Increase Innovation

ability of a system to recover from failures and mitigate disruptions

the degree to which a system is able to adapt to workload changes by provisioning and de-provisioning resources in an autonomic manner, such that at each point in time the available resources match the current demand as closely as possible

1. Edge Locations
2. Availability Zones
3. Regions

where end users access services located at AWS. They are located in most of the major cities around the world and are specifically used by CloudFront (CDN) to distribute content to end user to reduce latency.

Isolated locations within data center regions from which public cloud services originate and operate.

geographic locations in which public cloud service providers' data centers reside

a virtual network logically isolated from other virtual networks in the AWS Cloud.

virtual firewall that controls the traffic for one or more instances. When you launch an instance, you associate one or more security groups with the instance. You add rules to each security group that allow traffic to or from its associated instances.

Virtual machine sold as a service and runs its own copy of an operating system (OS).

a virtual computing environment, that enables customers to use Web service interfaces to launch instances with a variety of operating systems, load them with your custom applications, manage your network's access permissions, and run your image using as many or few systems as you need.
Flexible configuration and run apps at any scale.

cloud service that offers bundles of cloud compute power and memory for new or less experienced cloud users and derives its compute power from an EC2 instance and repackages it for customers who are new or inexperienced with cloud.
Use to manage simple websites and Static IP Address.

a cloud computing service that manages containers. It enables developers to deploy and manage scalable applications that run on groups of servers called clusters through application programming interface (API) calls

cloud computing execution model in which the cloud provider dynamically manages the allocation of machine resources.

Serverless computing platform service that runs code in response to events and automatically manages the compute resources required by that code.
You can run code without provisioning or managing servers.

file created by PuTTYgen (PuTTY Key Generator), a program used for generating keys for public-key cryptography; stores a private key generated by the program; PPK files are needed on Windows to access instance.

Compute service that lets you run code without provisioning or managing servers.
No servers to manage
Continuous Scaling
Supports variety of languages
Can invoke code with API Class
Intended for serverless and microservices applications.

Platform as a Service – you have the whole infrastructure and platform created for you in minutes
