What is cloud computing by Wikipedia?

“Cloud computing . . . is a style of computing where IT-related capabilities are provided ‘as a service,’ allowing users to access technology-enabled services ‘in the cloud’ without knowledge of, expertise with or control over the technology infrastructure that supports them.”

What is cloud computing by IBM?

Elasticity

VIRTUALIZATION

Cloud is a user experience and a business model

Cloud computing is an emerging style of IT delivery in which applications, data, and IT resources are rapidly provisioned and provided as standardized offerings to users over the web in a flexible pricing model

Cloud is an infrastructure management and services delivery methodology

Cloud computing is a way of managing large numbers of highly virtualized resources such that, from a management perspective, they

resemble a single large resource. This can then be used to deliver services with elastic scaling

What is different about cloud computing?

With cloud computing Without cloud computing

 Virtualized resources  Automated service management  Standardized services  Location independent  Rapid scalability  Self-service  Pay by use • Software

Multi-tenancy: Basics

Dedicated Legend:

In multi-tenant environments shared layers must behave as if they were setup in a dedicated fashion.

• This requires “multi-tenancy support” on the respective technology layer (infrastructure/OS, platform or application)

• If the implementation of a technology layer doesn’t inherently support multi-tenancy (i.e. being able to behave within on installation as if there were multiple dedicated ones), then it must be setup in a dedicated fashion.

Multi-tenancy: Shared vs. dedicated

In a cloud environment, there are two primary technology stacks where multi-tenancy is relevant:

• The management environment

• The managed environment (infrastructure, platform or application that is provided as a service)

Application

The amount of work required for setting up a new tenant depends on where the “multi-tenancy point” sits within the technology stack. The higher the multi-tenancy point, the less effort is required for setting up a new tenant (because more underlying technology is shared). Conversely, the higher the multi-tenancy point the more resources can be shared amongst tenants.

The grand challenge of security in the Cloud

 Consider a Cloud to be a complex, distributed SOA environment…

…with services in different security domains but connected together in a Cloud, …

… Then the Web Services protocol stack is the basis of standards based Cloud security

 Cloud Computing scales SOA service integration further up than an enterprise SOA environment

– Number of tenants, services, standards – Highly dynamic, agile
