CLOUD COMPUTING - Services

Concept of being able to use reusable, fine-grained components across a vendor’s network.

“As a Service” - suffix Low barriers to entry Available for Small business Resources to be shared by users Device independence

SaaSIaaSPaaSHaaS


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.

3Jainul A. Musani

Software as a Service (SaaS)


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.

4Jainul A. Musani



The provider does all the patching and upgrades as well as keeping the infrastructure running.

Cost Double-Edge Sword

Plan-01 : Pay for once and done it, then more you use more billed…

Plan-02 : Don’t pay.. Just use and billed…

7Jainul A. Musani



For Vendors (SaaS)Stronger protection of their intellectual property.Creating a continuous stream of income

8Jainul A. Musani



Many softwares lend to the (SaaS model)

Softwares that performs simple task without much interact with other systems.

9Jainul A. Musani



(SaaS model)

Customers who are not inclined to perform s/w development but have need of high-powered applications can also benefit.

SaaS – Advantages / Benefits


Other Benefits_• Familiarity with the WWW –• Smaller Staff• Customization• Better Marketing • Web Reliability• Security• More Bandwidth

16Jainul A. Musani

SaaS – Advantages / Benefits


Specific application computational need may not be suitable for SaaS.

Organization need to buy the software and install at their local machine.

Companies with common need of s/w may find the SaaS useful.

17Jainul A. Musani

SaaS – OBSTACLES


Lock-in vendors – a user pay a vendor for a specific application then unable to port the application to another vendor.

SaaS facing problem with Opensource availability and Cheaper Hardware.

SaaS – OBSTACLES


Platform As a Service is another application delivery model.PaaS supplies all the resources require to build applications and services completely from the Internet, instead of download and install software.

Other services include_ 1) Team collaboration2) Web service integration3) Database integration4) Security5) Scalability6) Storage7) State management 8) Versioning

23Jainul A. Musani



Downfall____

Lack of interoperability

Lack of portability among

providers

24Jainul A. Musani



Downfall____ If you create an application for one

cloud provider and decide to move to another provider – may not possible OR pay a high price.

If provider goes out of business, your application and data will be lost.

25Jainul A. Musani



PaaS offers__Creation of user interface, based on HTML or JavaScript

Automatic facilities forConcurrency Management

ScalabilityFailover Security

26Jainul A. Musani



PaaS Options__oSOAP (Simple Object Access

Protocol)oREST (Representational State

Transfer)

Which allows construction of multiple web services

called “mashup”27Jainul A.

Musani



PaaS is found in three different types of systems:

1) Add-on development facilities2) Stand alone environments3) Application delivery-only

environments

28Jainul A.

Musani



1) Add-on development facilitiesAllow existing SaaS applications to be customized.Often, PaaS developers and users are required to purchase subscriptions to the add-on SaaS application.

29Jainul A. Musani



2) Stand alone environmentsDo not include licensing, technical or financial dependencies on specific SaaS applications and are used for general developments.

30Jainul A. Musani



3) Application delivery-only environments

Supports hosting level services, like _ Security and on-demand scalability. Do not include development,

debugging and test capabilities.

31Jainul A. Musani



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

32Jainul A. Musani



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.

33Jainul A. Musani



Hurdles: Two main obstacles – developer faces1. Vendors use proprietary services /

development languages.2. Cost is higher to move application

between conventional hosts.

34Jainul A. Musani



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.

35Jainul A. Musani

HaaS – Hardware As a Servicer


36Jainul A. Musani



• Rather than purchase servers, software, racks, and having to pay for the datacenter space for them, the service provider rents those resources.

37Jainul A. Musani



HaaS allows to “rent” resources_

• Server space• Network equipment• Memory• CPU cycles• Storage space

38Jainul A. Musani



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.

39Jainul A. Musani



HaaS involves several pieces: Service level agreements Computer hardware Network Internet connectivity Platform virtualization

environment Utility computing billing

APPLICATIONS

CLOUD COMPUTING

The most common are storage and database. Take a closer look at storage and database functionality.

43Jainul A. Musani

APPLICATIONS

CLOUD COMPUTING 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.

44Jainul A. Musani

APPLICATIONS

STORAGE

CLOUD COMPUTING Database• Databases are repositories for

information with links within the information that help make the data searchable.

45Jainul A. Musani

APPLICATIONS

CLOUD COMPUTING MS SQL• Microsoft’s premier offering,

SQL Server • Microsoft SQL Server Data

Services (SSDS) [cloud extension of that tool in the spring of 2008]

51Jainul A. Musani

Database As Service

CLOUD COMPUTING 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. 52Jainul A.

Musani

Database As Service


Services]

Works as a data hub, synchronizing data on multiple devices so they can be accessed offline.

53Jainul A. Musani

Database As Service


Services]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.

CLOUD COMPUTING Intranets and the Cloud Developing your own in-house

“cloud” and what is used in its composition.

56Jainul A. Musani

Intranets and the Cloud

CLOUD COMPUTING Intranets and the CloudComponents There are two main components

in client/server computing: • servers and • thin or light clients.

57Jainul A. Musani


CLOUD COMPUTING 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.

58Jainul A. Musani


CLOUD COMPUTING 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.

59Jainul A. Musani


CLOUD COMPUTING

60Jainul A. Musani


CLOUD COMPUTING 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.
