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

The “Cloud Pyramid”

‘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

Commercial clouds

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

Cloud Service Level Agreements (CSLAs)

Mainly 2 Sections(M2S):

• Technical Terms and Conditions (TTC)

• Commercial Terms and Conditions (CTC)

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

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

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

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

• I had read this above article on 17th May 2010 Times of India paper (times business column) "Taking Computing to the cloud".
