What is a cloud ?

A cloud is a computing service that
  charges you based only on the
 amount of computing service that
             you use .

Cloud Computing Architecture




    SaaS               PaaS                IaaS

          Software as a service
          Platform as a service
       Infrastructure as a service

These three services encapsulate the Basic 6 cloud
              computing components.
Software as a Service (SaaS)

# Software as a Service (SaaS): In this model, 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.
Platform as a Service (PaaS)

# Platform as a Service (Paas): Here, a layer of software, or
development environment is encapsulated & offered as a
service, upon which other higher levels of service can be built.
The customer has the freedom to build his own applications,
which run on the provider‟s infrastructure. To meet
manageability and scalability requirements of the
applications, PaaS providers offer a predefined combination
of OS and application servers, such as LAMP platform (Linux,
Apache, MySql and PHP), restricted J2EE, Ruby etc.
Infrastructure as a Service (IaaS)

# Infrastructure as a Service (Iaas): IaaS provides basic
storage and computing capabilities as standardized services
over the network. Servers, storage systems, networking
equipment, data centre space etc. are pooled and made
available to handle workloads. The customer would typically
deploy his own software on the infrastructure.
How is it different ??? Cloud API

# One of the key Characteristics that distinguish cloud
computing from standard enterprise computing is that the
infrastructure itself is programmable.

# Instead of physically deploying servers,storage and
network resources to support applications, developers specify
how the same virtual components are configured and inter
connected.


# Including how virtual machine images and application
data are stored and retrieved from a storage cloud.


# Developers specify how and when components are deployed
through an API that is specified by the cloud provider
Cloud Computing Types
Public Cloud




Public clouds are owned and operated by third parties; they
deliver superior economies of scale to customers, as the
infrastructure costs are spread among a mix of users, giving
each individual client an attractive low-cost, “Pay-as-you-go”
model. All customers share the same infrastructure pool with
limited configuration, security protections, and availability
variances. These are managed and supported by the cloud
provider.
One of the advantages of a Public cloud is that they may be
larger than an enterprises cloud, thus providing the ability to
scale seamlessly, on demand
Private Cloud

Private clouds are built exclusively for a single enterprise. They
aim to address concerns on data security and offer greater
control, which is typically lacking in a public cloud. There are
two variations to a private cloud:On-premise Private Cloud:

# On-premise private clouds: , also known as internal clouds
are hosted within one‟s own data center.

# Externally hosted Private Cloud: This type of private cloud
is hosted externally with a cloud provider, where the provider
facilitates an exclusive cloud environment with full guarantee
of privacy. This is best suited for enterprises that don‟t prefer a
public cloud due to sharing of physical resources.
Hybrid Cloud




Hybrid Clouds combine both public and private cloud models.
With a Hybrid Cloud, service providers can utilize 3rd party
Cloud Providers in a full or partial manner thus increasing
the flexibility of computing. The Hybrid cloud environment is
capable of providing on-demand, externally provisioned
scale. The ability to augment a private cloud with the
resources of a public cloud can be used to manage any
unexpected surges in workload.
Cloud Computing Economics


# Avoid Capital Expenditure .

# Billed on utility/subscription.

# Terminate contract anytime.

# Lower cost of entry.
Clients in Cloud Computing Architecture

 Clients are the devices that the end
 users interact with, to manage their
      information on the cloud




             Thin Client

 Mobile                      Thick Client
Importance of telco in Cloud
            computing
  Telecom operators have a unique
opportunity to position themselves to
 capitalise on the growth of cloud
              services –

both as providers and
   adopters of the
     technology.
Cloud and the Telecom Advantage

#. Seen as a trusted partner, telecom operators with
cloud offerings become a natural choice for
enterprises taking advantage IP Internet Protocol
of the technology.


#. Telecom networks, is providing a synergistic
platform for operators to realise new revenues and
improve bottom lines. And those investing in the
capability LTE Long Term Evolution to provide
cloud services are opening the doors to holding an
elevated position in the Networked Society.
Cloud and the Telecom Advantage .....


#. As providers of cloud services, telecom operators
can manage connectivity,deliver cloudCapabilities
and leverage network assets to enhance cloud
offerings.


#.Telecom operators also benefit from cloud
computing as users by transferring selected business
functions to the cloud just as any large enterprise
would.
Grid computing
Grid computing is often confused with cloud computing,
but they are quite different. Grid computing applies the
resources of numerous computers in a network to work on
a single problem at the same time.
- Cost effective way to use a given amt of computer
  resource.
- Way to solve problems that need tremendous computing
  power.
- The resource of several computers can be shared
  cooperatively, without one computer managing the other.
Cloud Broker
  “The future of cloud computing will be permeated
 with the notion of brokers negotiating relationships
 between providers of cloud services and the service
                      customers”




     “In this context, a broker might be software,
 appliances, platforms or suites of technologies that
enhance the base services available through the cloud.
 Enhancement will include managing access to these
 services, providing greater security or even creating
               completely new services.”
Cloud Broker - Types

The cloud broker creates a layer of abstraction b/w user and providers
so that the end users can see one cohesive view of all of the services



 #. Cloud Service Intermediation: Building services atop
 an existing cloud platform, such additional security or
                management capabilities.


      #.Aggregation: Deploying customer services over
                 multiple cloud platforms.


 #. Cloud Service Arbitrage: Brokers supply flexibility and
 "opportunistic choices" - and foster competition between
                          clouds .
