Welcome to the world of

Cloud Computing

What is cloud computing?• Cloud computing is a comprehensive solution that delivers IT

as a service. • Computers in the cloud are configured to work together and

the various applications use the collective computing power as if they are running on a single system.

• The flexibility of cloud computing is a function of the allocation of resources on demand.

• Resources are used as an aggregated virtual computer• Cloud configuration provides an environment where

applications execute independently without regard for any particular configuration.

Cloud computing - Definition

Cloud computing is a new style of computing where IT infrastructure is available as a ubiquitous, easily accessible, and reliable utility service conceptually similar to the telephone or electricity.

Why cloud computing?

• The main advantage of using cloud computing facility is that customers do not have to pay for infrastructure installation and maintenance cost.

• As a user of cloud computing you have to pay the service charges according to your usage of computing power and other networking resources.

• No need to worry about software updates, installation, email servers, anti-viruses, backups, web servers and both physical and logical security of your data.

5 Essential Cloud Characteristics

• On-demand self-service

• Ubiquitous network access

• Resource pooling– Location independence– Homogeneity

• Rapid elasticity

• Measured service

Three Cloud Service ModelsSoftware as a Service ‘SaaS’

SaaS features a complete application offered as a service on demand. A single instance of the software runs on the cloud and services multiple end users or client organizations.

Three Cloud Service ModelsPlatform as a Service ‘PaaS’

Platform as a service encapsulates a layer of software and provides it as a service that can be used to build higher-level services.Someone producing PaaS might produce a platform by integrating an OS, middleware, application software, and even a development environment that is then provided to a customer as a service

Three Cloud Service ModelsInfrastructure as a Service ‘IaaS’

Infrastructure as a service delivers basic storage and compute capabilities as standardized services over the network. Servers, storage systems, switches, routers, and other systems are pooled and made available to handle workloads that range from application components to high-performance computing applications.

Two Technologies for Agility

• Virtualization:The ability to run multiple operating systems on a single physical system and share the underlying hardware resources*

• Cloud Computing:“The provisioning of services in a timely (near on instant), on-demand manner, to allow the scaling up and down of resources”**

* VMware white paper, Virtualization Overview

** Alan Williamson, quoted in Cloud BootCamp March 2009

Changing IT Job Oppurtunities

High pressure on Businesses to create new Value Adds continuously to survive competition

High pressure on Delivery and Technology teams to reduce investment without impacting the service delivery quality

Natural choice is Cloud Computing platform

IT professional must have end-to-end IT Management skills, no more domain specific knowledge at entry level

Virtualization skills is mandatory now for every IT professional

Even Networking Engineers must know Virtualization because they have to now manage “Virtual switches”

Technology Domains to look at:

• Important areas include:• 1. Provisioning and management• 2. Monitoring and protecting• 3. Service management• 4. Virtualization • 5. Automation • 6. Security and compliance• 7. Performance optimization

Cloud careers & Roles

• Business liaison: Move skills up the stack in the decision process.

• Hone expertise to the business from within IT. • Move into design and architecture roles. • Determine whether to focus in-house or off-

premise, define options whether the organization decides to stay on-premise or moves to the cloud.


• Datacenter manager:• Reposition datacenter skills towards the

hosted datacenter.• Enhance automation skills. • Work in standardized environments and with

standardized applications as an option.• Performance optimization. • Acquire best practices skills


• Security specialist:• Help businesses move core business processes and

data securely to private, public, or hybrid cloud solutions.

• Security specialists need to stay abreast of new security models and technologies :

• Data Protection Skills, • Privacy Standards, • Securing Message Integrity • Federated Identity Management, • Authentication Methods, • Auditing.


• Software architect:• Serve as a link between the organization’s technical and

business staff.• Design and build complex distributed systems that exist both

outside and inside an enterprise and the cloud.• To build infrastructure, platform, and software clouds. • To understand how to design and construct multi-tenant and

virtualized systems • Manage thousands of simultaneous users and isolate higher

levels of the stack from physical component failures.


• The Cloud Developer• The cloud developer will need to understand how applications

are designed, developed, and deployed for a PaaS. The skills developers need to invest in to prepare for the cloud include the following:

• Identity management • Windows Communication Foundation (WCF)and Rich Internet

Application (RIA) services • Connects• Middleware • Architecting Cloud Solutions


• Database Administrator Opportunities• Database administrators (DBAs) who are able to design and

manage databases anywhere also emerge as an important role. DBAs in a cloud environment need to invest in skills like architecting a cloud strategy (e.g., story type, cost) and identifying potential data to move to cloud storage (Windows Azure, SQL Azure). To take advantage of the scaling nature of the cloud, DBAs need to be aware of the new storage services. Windows Azure storage services provide scalable blob, queue, and table storage services, and SQL Azure provides a cloud-based relational database service built on Microsoft® SQL Server® technologies
