This document discusses cloud computing and cloud testing. It introduces cloud computing concepts like virtualization, sharing computing resources, reducing costs and improving scalability. It describes the different cloud delivery models of SaaS, PaaS and IaaS. The document also discusses the types of cloud (private, public and hybrid), forms of cloud testing, types of cloud testing including functional and non-functional, benefits of cloud testing like availability and low cost, and challenges of cloud testing like security, performance and unavailability of configurations.

INTRODUCTION TO CLOUD
COMPUTING
Ø Virtualization-Backbone of Several enterprises.
Ø Sharing Computing resources across several OS
Ø Reduce Capital Costs, Improve Scalability
Ø Easy administration of IT Infrastructure
As- a- Service (SW, Platform, Infrastructure)
Virtualization=Cloud
Computing

Example
● Email Communication
● No Need To Upgrade Local storage
● The Virtual Office
● Collaboration Made easy

Getting Familiar With Cloud Testing
Lets Understand Using Below Delivery Models.
Software as a Service (SaaS)
Platform as a Service (PaaS)
Infrastructure as a Service (IaaS)
Storage,
Network devices,
Compute Servers
Operating Systems,
Middleware
Applications/
Products

Cloud formation is of three types:
Private: Restricted access managed by the firewall of an
organization Its availability is specific to the organization users. Pool of
resources available only to a specific organization giving greater control
and privacy.
Public: Services are available to everyone and resources are
allocated on demand ( Services to multiple clients using same shared
infrastructure)
Hybrid: Combination of both.
TYPES AND FORMS OF CLOUD

Cloud Testing Forms
● Testing whole cloud (Cloud &SaaS vendors as
well as end users)
● Testing within cloud ( Only cloud vendors)
● Testing across cloud
● SaaS testing in cloud

7. 2/25/15
Testing Types In Cloud
Functional
●
System Verification Testing
● Acceptance Testing
● Interoperability Testing
Non-Functional
●
Availability Testing
● Multi Tenancy Testing
● Performance Testing
● Security Testing
● Disaster Recovery Testing
● Scalability Testing

8. 2/25/15
Benefits Of Cloud Testing
●
Availability of test environment as and when required.
● Low Cost
● Easy Customizable
● Scalability

Challenges
Challenge 1: Security
Challenge 2: Performance
Challenge 3: Unavailability of certain configuration
Challenge 4: Integration testings
