Software as a Service (SaaS)
An application is hosted as a
service to customers who access it
via the Internet.
When a service is hosted off-site,
the customer doesn’t have to
maintain or support it.

The main aim is that you use
the software out of the box
as is and don’t need to make
a lot of changes or require
integration to other systems.

28. CLOUD COMPUTING - Services
PaaS – Platform As a Servicer
PaaS is found in three different types
of systems:
1) Add-on development facilities
2) Stand alone environments
3) Application delivery-only
environments
Jainul A.
28

29. CLOUD COMPUTING - Services
PaaS – Platform As a Servicer
1) Add-on development facilities
Allow existing SaaS applications to
be customized.
Often, PaaS developers and users
are required to purchase
subscriptions to the add-on SaaS
application.
Jainul A.
29

30. CLOUD COMPUTING - Services
PaaS – Platform As a Servicer
2) Stand alone environments
Do not include licensing, technical or
financial dependencies on specific
SaaS applications and are used for
general developments.
Jainul A.
30

31. CLOUD COMPUTING - Services
PaaS – Platform As a Servicer
3) Application delivery-only
environments
Supports hosting level services, like _
Security and on-demand scalability.
Do not include development, debugging
and test capabilities.
Jainul A.
31

32. CLOUD COMPUTING - Services
PaaS – Platform As a Servicer
Trends Towards Adoption:
PaaS faces the same sorts of factors
in its adoption as SaaS_
1) Ability of geographically isolated
development teams to work
together.
2) Ability to merge web services from
multiple resources
Jainul A.
32

33. CLOUD COMPUTING - Services
PaaS – Platform As a Servicer
Trends Towards Adoption:
3) Ability to realize cost saving from
using built-in infrastructure services
for security, scalability, and failover,
rather than having to obtain and test
them separately.
4) Cost saving from using higher level
programming abstractions.
Jainul A.
33

34. CLOUD COMPUTING - Services
PaaS – Platform As a Servicer
Hurdles:
Two main obstacles – developer faces
1. Vendors use proprietary services /
development languages.
2. Cost is higher to move application
between conventional hosts.
Jainul A.

35. CLOUD COMPUTING - Services
HaaS – Hardware As a Servicer
 Hardware as a Service (HaaS) is
the next form of service available
in cloud computing.
 Where SaaS and PaaS are
providing applications to
customers, HaaS doesn’t.
Jainul A.
35

36. CLOUD COMPUTING - Services
HaaS – Hardware As a Servicer
Jainul A.
36

37. CLOUD COMPUTING - Services
HaaS – Hardware As a Servicer
• Rather than purchase servers,
software, racks, and having to
pay for the datacenter space for
them, the service provider rents
those resources.
Jainul A.
37

38. CLOUD COMPUTING - Services
HaaS – Hardware As a Servicer
HaaS allows to “rent” resources_
• Server space
• Network equipment
• Memory
• CPU cycles
• Storage space
Jainul A.
38

39. CLOUD COMPUTING - Services
HaaS – Hardware As a Servicer
1) Infrastructure can be dynamically
scaled up or down, based on the
application resource needs.
2) Multiple tenants can be on the
equipment at the same time.
3) Resources billed based on a utility
computing basis. Providers charge
by how many resources are
consumed.
Jainul A.
39

40. CLOUD COMPUTING - Services
HaaS – Hardware As a Servicer
HaaS involves several pieces:
 Service level agreements
 Computer hardware
 Network
 Internet connectivity
 Platform virtualization environment
 Utility computing billing

STORAGE
• Similar to HaaS, one of the uses for
cloud computing is simply storage.
• General benefits of cloud
computing—User does not
responsible to buy equipment, pay
to run it, and pay to cool it.
Jainul A.

MS SQL [SQL Server Data Services]
• SSDS looks similar to Amazon’s
SimpleDB, with a straightforward,
schema-free data storage, SOAP
or REST APIs, and a pay-as-you-go
payment system.
• It is also able to start small and
scale larger as needed.
Jainul A.

Three core concepts:
• Authority: An authority is both a billing
unit and a collection of containers.
• Container: A container is a collection
of entities and is what you search within.
• Entity: An entity is a property bag of
name and value pairs.

Intranets and the Cloud
The servers house the applications
your organization needs to run,
And the thin clients—which do not
have hard drives—display the results.

Hypervisor Applications
Applications like VMware or
Microsoft’s Hyper-V allow you to
virtualizes your servers so that
multiple virtual servers can run on
one physical server.

Intranets and
the Cloud
Hypervisor Applications
These sorts of solutions provide the tools to
supply a virtualized set of hardware to the
guest operating system. They also make it
possible to install different operating
systems on the same machine. For example,
you may need Windows Vista to run one
application,
while
another
application
requires Linux. It’s easy to set up the server
to run both operating systems.
