This document discusses cloud computing, including definitions, advantages, and types of cloud services. Cloud computing provides scalable infrastructure over networks to host applications, data, and files. It reduces costs for computation, hosting, storage, and delivery. The cloud allows access to information from anywhere and removes the need to store data locally. Small businesses can use cloud storage instead of purchasing hardware. The cloud offers low barriers to entry, scalability, multi-tenancy, and device independence. Companies move to the cloud to reduce costs, optimize personnel usage, and gain scalability. The cloud delivers infrastructure, self-service management, and pay-per-use models. Both consumers and businesses widely use cloud services like email, social media, reservations

1. CLOUD COMPUTING
Sonia Nagpal

2. Definition
• Cloud computing is
– a computing paradigm,
– where a large pool of systems are connected
in private or public networks,
– to provide dynamically scalable infrastructure
for application, data and file storage.
– Advantages : The cost of computation,
application hosting, content storage and
delivery is reduced significantly.

3. How can you use the cloud?
• The cloud makes it possible for you to access your
information from anywhere at any time.
• The cloud removes the need for you to be in the same
physical location as the hardware that stores your data
• Small companies can store their information in the
cloud, removing the cost of purchasing and storing
memory devices.

4. Cloud Services Offers
• Low barriers to entry, making it available to
small businesses
• Large scalability
• Multi-tenancy, resource sharing
• Device Independence, independent of
hardware

5. Why the rush to the cloud?
• Reduced cost: Cloud computing can reduce both capital
expense
– (CapEx) and operating expense (OpEx) costs because
resources are only acquired when needed and are only
paid for when used.
• Refined usage of personnel: Using cloud computing frees
valuable
– personnel allowing them to focus on delivering value
rather than maintaining hardware and software.
• Robust scalability: Cloud computing allows for immediate
scaling, either
– up or down, at any time without long-term commitment.

8. Uses of Cloud Computing ?
• Consumers and businesses utilize the cloud on a
daily basis even if they're not aware of it
– Email
– Social sites
– Reservations
– Post Photos
– E-Commerce
– Online document storage
– Banking
– Entertainment

9. Cloud Computing Benefits
Reduced Cost
Increased Storage
Flexibility

10. Types of clouds
• Public Cloud - A public cloud can be accessed by any
subscriber with an internet connection and access to the
cloud space.
• Private Cloud - A private cloud is established for a specific
group or organization and limits access to just that group.
• Community Cloud - A community cloud is shared among
two or more organizations that have similar cloud
requirements.
• Hybrid Cloud - A hybrid cloud is essentially a combination
of at least two clouds, where the clouds included are a
mixture of public, private, or community.

11. Cloud Computing Models

12. Cloud Computing Challenges
Data Protection
• fear losing data to competition and the data confidentiality of
consumers.
• the actual storage location is not disclosed, adding onto the security
concerns of enterprises
Data Recovery and Availability
Management Capabilities
• the management of platform and infrastructure is still in its infancy
• “Auto-scaling‟ is a challenge
Regulatory and Compliance Restrictions

13. Data Recovery & Availability
Appropriate clustering and Fail over
Data Replication
System monitoring (Transactions monitoring, logs
monitoring and others)
Maintenance (Runtime Governance)
Disaster recovery
Capacity and performance management

14. Software as a Service (SaaS)
– a complete application is offered to the customer,
as a service on demand.
– A single instance of the service runs on the cloud
& multiple end users are serviced.
– On the customers‟ side, there is no need for
upfront investment in servers or software licenses,
while for the provider, the costs are lowered, since
only a single application needs to be hosted &
maintained.
– Google, Salesforce, Microsoft, Zoho

15. SAAS Offerings used in
• CRM
• Video Conferencing
• IT Service Management
• Accounting
• Web Analytics
• We content management

16. Platform as a Service (PAAS)
• PaaS delivers a computing platform and/or
solution stack as a service, often consuming
cloud infrastructure and sustaining cloud
applications.
• It provides a consistent hardware and
software infrastructure aimed entirely at
running applications, such as within Microsoft
Windows Azure.

17. Software as a Service
• SaaS is “software deployed as a hosted service
and accessed over the Internet.”
• The user accesses applications running on a
cloud infrastructure via a web browser or
other client software and IT professionals are
not required to manage the underlying cloud
infrastructure to administrate their
applications.

21. Datacenter Managers
• Administration and configuration tasks
• Service management and process automation
• Datacenter operations
– to manage the datacenter,
– engage in network management,
– user account management,
– server management and
– application management.

22. 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.

23. Datacenter manager
• Reposition datacenter skills toward the hosted
datacenter.
• Enhance automation skills.
• Work in standardized environments and with
standardized applications as an option.
• Become good at management applications,
scripting, and performance optimization.
• Acquire best practices skills, such as
information services technology management.

24. 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,
– such as data protection skills,
– privacy standards,
– securing message integrity (encryption, digital signing and
malware protection),
– federated identity management,
– authentication methods,
– and auditing.

25. Software architect
• Serve as a link between the organization’s technical
and business staff.
• Architects are asked to design and build complex
distributed systems that exist both outside and inside
an enterprise and the cloud.
• They need to acquire the new skills required to build
infrastructure, platform, and software clouds.
• They need to understand how to design and construct
multi-tenant and virtualized systems that can manage
thousands of simultaneous users and isolate higher
levels of the stack from physical component failures.

26. 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

27. Architecting
• Architecting addresses computer service
applications and cost considerations.
• The investment now is in composite applications
— and that has cost implications.
• Developers will need to understand their data
storage options and data partitioning.
• They don’t need one single store for all their
data; it can be put in a particular location. The
question becomes where to keep the data.
• It behooves developers to think about how to
design applications with regard to where data is.

28. 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.
