6/22/2018 Dr. Asif Qumer Gill 3 What is a cloud? “a 'cloud' is an elastic execution environment of resources involving multiple stakeholders and providing a metered service at multiple granularities for a specified level of quality (of service).” (European Commission Report 2010)
What is a cloud computing? ‘X’ as a Service (XaaS)
Infrastructure as a Service (IaaS)
Shared managed pool of configurable and scalable resources (e.g. network, middleware, web/ application servers, email servers, database/storage servers)
Platform as a Service (PaaS)
Shared platform for custom software application configuration, development, testing and deployment
Software as a Service (SaaS)
Shared instance of a software application as a service accessible via internet browser or client based role access and sharing rules
Application development
Multitenant development environment
Forms, reports, workflows, role hierarchy, sharing model, meta-data, data export, import, reusable, customiseable, APIs, bulk processing
Collaborative and integrated development environment
Single point of contact for data management, code development, review, automated test and merge

Private cloud - internal to organization
Public cloud - made available to public (PAYG)
Hybrid – a mix of private and public cloud
Community cloud – multiple organisations collaborate
Business Value
Easy to use
Availability of service and support - flexible SLA (PAYG)
Reduce infrastructure support and maintenance cost
Focus on core business
Capital to operational expenditure
Application
Adaptive software development and management
Collaborative business process and information management

How can we create data objects in a multitenant environment?
How can we secure the tenant-specific data in a shared multitenant environment?
How can we make real-time changes in the apps interface and code without impacting its functionality and availability?
How can we scale response time in a shared environment?

It will undoubtedly transform the IT industry, but it will also profoundly change the way people work and companies operate. It will allow digital technology to penetrate every nook and cranny of the economy and of society.” (Economist 2008) Resources Amazon, http://aws.amazon.com/, Amazon web services
