What is a Cloud?
Cloud Computing defined
• “… a style of computing in which dynamically scalable and often virtualized resources are provided as a service over the Internet”
– Wikipedia
Cloud Computing defined
• “Clouds are hardware-based services offering compute, network and storage capacity where: Hardware management is highly abstracted from the buyer, Buyers incur infrastructure costs as variable OPEX, and Infrastructure capacity is highly elastic”
– McKinsey & Co. Report: “Clearing the Air on Cloud Computing”
Cloud Computing defined
• “Cloud computing has the following characteristics:
1. The illusion of infinite computing resources…
2. The elimination of an up-front commitment by Cloud users…
3. The ability to pay for use…as needed…”
– UCBerkeley RADLabs
Cloud Computing defined
• “... a pay-per-use model for enabling available, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.” – National Institute of Standards and Technology
(NIST)
Cloud Computing defined
• “Clouds are a large pool of easily usable and accessible virtualized resources (such as hardware, development platforms and/or services). These resources can be dynamically re-configured to adjust to a variable load (scale), allow-ing also for an optimum resource utilization. This pool of resources is typically exploited by a pay-per-use model in which guarantees are offered by the Infrastructure Provider by means of customized SLAs.” – Paper by Vaquero et. al.: “A break in the clouds:
towards a cloud definition”
What is a Cloud?
• Datacenter with an API
What is a Cloud?
• Timesharing 2.0
Common Ground?
• Pay-per-use (no commitment, utility prices)
• Elastic capacity - scale up/down on demand
• Self-service interface
• Resources are abstracted / virtualized
Types of Cloud
• Public Cloud
• Private Cloud
• Hybrid Cloud
Public vs. Private Cloud
Public Cloud Private Cloud
Variable expenses (OPEX) Capital expenses (CAPEX)
Less control More control
More locations Fewer locations
Less secure? More secure?
X-aaS Anything as a Service
