Cloud Computing Concepts

Traditional Procurement Process: Traditional systems often "buy first, use later," purchasing server capacity in advance. This may result in under-utilization or over-capacity and thus inefficient spending.
Cloud Computing Use Case: In contrast to traditional models, cloud computing scales on demand, allowing for temporary increases in capacity for events like holiday shopping by resellers, and avoid wasting resources on unused capacity.

What is Cloud Computing?

On-demand delivery of computing power, databases, storage, networking, software
Uses the internet to deliver services
Pay-as-you-go pricing
No upfront infrastructure investment
Provision exactly the right resources as needed

NIST Cloud Computing Model

Shows essential characteristics and service models of cloud computing.

Essential Cloud Characteristics

On-demand self-service
Broad network access
Resource pooling
Rapid elasticity
Measured service

On-Demand Self-Service

Services consumed as needed, without human intervention from the cloud provider.
Organizations provision resources (servers, storage, web apps) when needed.
Organizations can provision resources using their internal IT staff.

Broad Network Access

Cloud resources accessible across a network.
Can be an internal network, internet connection, or a combination.
May be globally accessible.

Resource Pooling

Cloud service providers pool network, storage, and compute resources.
Allocate these pooled resources to customers on demand.
Leverage economies of scale.

Rapid Elasticity

Resource requirements can adjust (increase or decrease) throughout the year.
Cloud-based resources easily adjust as needed.
Avoid paying for underutilized resources.

Measured Service

Cloud resource utilization is measured by the cloud service provider.
Billing is based on actual resource usage.

Cloud Service Models

Software as a Service (SaaS)
Platform as a Service (PaaS)
Infrastructure as a Service (IaaS)
Anything as a Service (XaaS)

Infrastructure as a Service (IaaS)

Provides all computing resources in a virtual environment.
Cloud Service Provider (CSP) manages hardware.
Consumers manage virtual machines.
Businesses deploy the exact number of servers needed.
Elastic scaling for agile needs.
Reduced capital expenditures for hardware and licenses.
Target audience: IT administrators.
Example: AWS EC2 (Virtual Machines)

Platform as a Service (PaaS)

Programming language execution environment.
Developers can build, compile, and run programs.
Cloud service provider manages hardware and operating system.
Provides platform maintenance.
Customers use the platform for business operations.
Commonly used for development environments and databases.
Target audience: Developers, Database Administrators.
Examples: Google App Engine, AWS Elastic Beanstalk.

Software as a Service (SaaS)

On-demand service, platform-independent software.
Doesn't require software installation.
Vendor manages computing resources.
Consumers directly use software across a network.
Cloud service provider manages underlying hardware, operating systems, and patches.
Typically licensed via subscription.
High adoption rate.
Hardware and OS agnostic.
Target audience: End users.
Examples: Microsoft Office 365, Google Apps, WebEx, Dropbox, Netflix

Cloud Service Models Summary

Shows a comparison of the three primary cloud service models (IaaS, PaaS, SaaS).
Includes definitions, advantages, users, and examples of each model.

Advantages of Cloud Computing

Trade capital expense for variable/operating expense.
Benefit from massive economies of scale.
Stop guessing about capacity (elasticity.)
Increase speed and agility.
Stop spending money on running/maintaining data centers.
Go global in minutes
