This document provides an overview of cloud computing and testing in the cloud. It discusses key aspects of cloud computing including pay-per-use models, virtual server pools, and various cloud deployment models. It then covers cloud service level agreements and their technical and commercial terms. The document outlines different strategies for testing in the cloud including automation, functional testing, and monitoring. It also discusses challenges like security and reliability and how defects are tracked. Overall the document is providing guidance on testing applications and infrastructure deployed in cloud environments.

1. Cloud Testing
Speaker : Mrityunjaya Hikkalgutti

Overview of Cloud
• Pay by the drink model
• Pay for extra resources when needed
• Better economics
• “A pool of abstracted, highly scalable, and managed compute
infrastructure capable of hosting end-customer applications and
billed by consumption1”
• Virtualized server pool
• Measured service

3. The “Cloud Pyramid”

4. ‘Why’ Cloud Migration
• Nothing to buy
− Cloud computing, a solution to rescue organizations to focus on their
core business rather than worrying about the investment and
maintenance of their business IT infrastructure.
• Cancel service immediately
• Virtually infinite storage capacity
• Efficient, reliable load distribution layer
• Nothing is there to Throw it out
• Just send cancellation request
• High availability large-store database

5. Commercial clouds

6. 4 Cloud Deployment Models
• Private cloud
− enterprise owned or leased
• Community cloud
− shared infrastructure for specific community
• Public cloud
− Sold to the public, mega-scale infrastructure
• Hybrid cloud
− composition of two or more clouds

7. Cloud Service Level Agreements (CSLAs)
Mainly 2 Sections(M2S):
• Technical Terms and Conditions (TTC)
• Commercial Terms and Conditions (CTC)

8. Technical Terms and Conditions (TTC)
• Technical Critical Areas
•Consistency
•Compatibility
•Availability
•Scalability
•Environment
•Stress
•Load
•Volume
•Reliability
•Tuning
•Security / IP protection
•Disaster Recovery Centers
•Min and Max System break down time
•Connectivity
•Multi tenancy

9. Commercial Terms and Conditions (TTC)
• Commercial Critical Areas
•List of service with commercial terms
•Each Service with Minimum & Maximum Usage with cost
•Service Offer validity
•Minimum & Maximum trail period Duration for any service
•Prepaid Services
•Postpaid services

10. Cloud Solution Challenges
• Security
• Reliability
• Manageability
• Disaster Recovery Centers

11. •Cloud SLA Analysis

•Designing
•Coding
•Development Environment set up

19. Application Monitoring during performance tests
 Application response time (end to end)
 Application response times for different bandwidth simulation(56K
and Broad band)
 Page hits/Sec
 Page views/Sec
 Transactions /Sec
Hardware Monitoring during performance tests
 CPU and memory utilization for web servers, Application servers and
database servers
 Monitoring of Firewalls
Cloud Key Performance Measurements

20. Save The Testing Effort & Cost By Using Cloud
• SAP –offering ERP Solution “Business By- Design (BByD)”
• In case of BByD, SAP hosts the solution, maintains it and upgrades it
• BByD’s first customer in India:
.
− 2-mbps line to draw the solution
− SAP at the rate of Rs 5610 per user per month
− has taken it for 25 users
− total cost comes around 1.4lkhs per month
− They are delighted with this choice
Cost Saved :If They had gone for a traditional ERP application, it would have required a capital expenditure of Rs
25- 30 lakh, and another Rs 10-12 lakh a year to keep it running.
• “Turn off the lights” = turn off servers you aren’t using
• Pay for only what you use
• No need to buy in advance
• Zero Capital Outlay
Effort saved :Testing, Installation & maintenance
• I had read this above article on 17th May 2010 Times of India paper (times business column) "Taking Computing to
the cloud".
