What is Cloud?

2014 @eglute @IcchaSethi

Cloud Computing Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. (NIST definition)

2014 @eglute @IcchaSethi

Why Cloud Computing? §  Main features of cloud computing: −  Rapid provisioning •  I want it now!

−  Scalability •  Go from 1 to many in minutes

−  Flexibility •  Different cloud options to choose

−  Accessibility •  Anytime from anywhere

−  Affordability •  No fixed hardware or other physical infrastructure costs

Types Of Cloud Deployment Models

§  Different types of clouds mean not necessarily different technology, but different infrastructure deployment model as well as service and access levels −  Public Cloud −  Private Cloud −  Hybrid Cloud

2014 @eglute @IcchaSethi

Public Cloud §  Multi-tenant environment, where you buy a “server slice” in a cloud computing environment that is shared with a number of other clients or tenants

2014 @eglute @IcchaSethi

Private Cloud §  Computing platform that is implemented within the corporate firewall, under the control of the IT department.

2014 @eglute @IcchaSethi

Hybrid Cloud §  Integrated cloud service utilizing both private and public clouds to perform distinct functions within the same organization.

2014 @eglute @IcchaSethi

Service Levels §  Cloud Infrastructure is available. §  Now what?

2014 @eglute @IcchaSethi

Types Of Clouds

§  Pick two: −  Deployment model •  Public •  Private •  Hybrid

−  Service Level •  IaaS •  PaaS •  SaaS 2014 @eglute @IcchaSethi

Service Levels §  Who are you: −  Do it yourself? −  Let someone else do it?

Different Service Levels §  Do everything yourself §  IaaS: infrastructure as a service §  PaaS: platform as a service §  SaaS: software as a service

2014 @eglute @IcchaSethi

IaaS §  Infrastructure as a service §  Need to know at least basic system administration −  Users are given a slice of compute resource, i.e., virtual machine with an operating system, network connectivity, and some basic tools. −  User responsible for installing everything else other than OS. −  Best for custom environments (dev, qe, prod)

2014 @eglute @IcchaSethi

PaaS §  Platform as a service, developer’s best friend −  No need to know administrative tasks −  Comes with application and software stack setup •  Java, Ruby, PHP, Python, etc −  Comes with tools to easily deploy applications

2014 @eglute @IcchaSethi

SaaS §  Software as a service: subscription, or ondemand software §  No setup for user §  Centralized
