27 September 2015 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

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

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 lakh, and another Rs 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".
