2. Welcome to the world of
Cloud Computing

3. 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.

4. 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.

5. 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.

13. 5 Essential Cloud Characteristics
• On-demand self-service
• Ubiquitous network access
• Resource pooling
– Location independence
– Homogeneity
• Rapid elasticity
• Measured service

14. Three Cloud Service Models
Software 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.

15. Three Cloud Service Models
Platform 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

16. Three Cloud Service Models
Infrastructure 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”

31. 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

32. 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.

33. Cloud careers & Roles
• 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

34. Cloud careers & Roles
• 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.

35. Cloud careers & Roles
• 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.

36. Cloud careers & Roles
• 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

37. Cloud careers & Roles
• 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
