What is cloud computing? Webster:"the practice of storing regularly used computer data on multiple servers that can be accessed through the Internet“. An innovative way of conducting every day business and entertainment.
Types of Cloud Computing Web-based cloud services services let you use certain web service functionality, rather than using fully developed applications SaaS (Software as a Service) providing a given application to various users Platform as a Service deviation of SaaS to you run your personal applications that you execute in the cloud
Types of Cloud Computing Utility cloud services virtual storage and server options (i.e iCloud or DropBox) Managed services cloud provider utilizes an application rather than end-users Service commerce provides a hub of services which the end-user can interact with
How does it works? Nothing is local Data is uploaded Stored in data centers or data farms Data is copied several times over Very difficult to lose
What are the key characteristics? Dynamic computing infrastructure IT service-centric approach Self-service based usage model Minimally or self-managed platform Consumption-based billing
How many layers and their functionalities? The Hardware Layer The Virtualization Layer Infrastructure as a Service (IaaS) Platform as a Service (PaaS) Software as a Service (SaaS) The Client Layer
Hardware Layer Also know the server layer Physical hardware that provides actual resources that make up the cloud. Redundancy
Virtualization Layer Most scalable and flexible layer Various operating systems being installed as virtual machines Virtual machines can be created and deleted at will
Infrastructure as a service (IaaS) Provides companies with, computing resources including Servers Networking Storage Data center space All on a pay-per-use basis
Platform as a service (PaaS) Provides a cloud-based environment with everything required to support the complete lifecycle of building and delivering cloud applications Customers do not manage their virtual machines.
Software as a service (SaaS) Run on distant computers “in the cloud” that are owned and operated by others Services at the software level consist of complete applications that do not require development.
Client Layer User interface to which cloud computing services are delivered. Client layer hardware can include personal computers web browsers mobile devices
Amazon EC2 Amazon Elastic Compute Cloud is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers.
To use Amazon EC2 Select a pre-configured Amazon Machine Image or create a custom AMI. Configure security and network access on your Amazon EC2 instance. Choose which instance type you want, then start, terminate, and monitor. Determine whether you want to run in multiple locations. Pay only for the resources that you consume.
