Cloud computing provides on-demand access to shared computing resources like networks, servers, storage, applications and services available over the internet. It offers advantages like cost effectiveness, dynamic scaling, on-demand self-service and measured service. There are three main service models - Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS). The document then discusses Google Cloud Platform's IaaS offering called Google Compute Engine and its PaaS offering called Google App Engine.

2.  What is Cloud Computing?
 Why Cloud Computing?
 Cloud Computing Service Models
 IaaS – PaaS – SaaS
 Cloud Computing Deployment Models
 Private – Public – Hybrid – community
 Google Cloud Platform
 Google Computing Engine
 Google App Engine

4.  Cloud Computing is a range of services which
are provided by an Internet-based.
 Cloud Computing provide shared pool of
configurable computing resources (e.g.,
networks, servers, storage, applications, and
services)
 CC=On demand computing=pay as you go
computing.

6.  On-Demand Self-Service: Users can provision servers and networks with
little human intervention.
 Resource Pooling: Multiple users can access clouds that serve other
consumers according to demand. Resources include storage, processing,
memory, network bandwidth, and virtual machines.
 Broad Network Access:Any computing capabilities are available over
the network. Many different devices are allowed access through
standardized mechanisms.
 Dynamic Scaling : Capabilities can be rapidly and elastically provisioned
for unlimited and can be purchased in any quantity at any time.
 Measured Service: Resource usage can be monitored, controlled and
optimized automatically through metering capabilities.
 Cost Effective

7.  Software as a Service (SaaS):
Provides the consumer the ability to use the software in a
cloud environment, such as web-based email for example.
 Platform as a Service(PaaS):
Provides the consumer the ability to deploy
applications through a programming language
or tools supported by the cloud platform provider.
 Infrastructure as a Service(IaaS):
Provides infrastructure such as computer instances,
network connections, and storage so that people
can run any software or operating system.

9.  A private cloud:
operates for a single organization, but can be managed on-
premise or off-premise.
 A public cloud :
Public clouds are owned and operated by companies that
offer rapid access over a public network to affordable
computing resources. It is managed by providers.
 A hybrid cloud:
It is a composition of both public and private clouds, or a
hybrid model for cloud computing may involve both virtual
and physical servers.

13.  Infrastructure as a Service (IaaS)
 Can take virtual machine Linux (Ubuntu or
Centos).
 The machine one to eight virtual cores
 Persistent disks and access to Google cloud
storage.
 Control Network
 Using static or dynamic addresses.
 Configure firewall

14.  Is Google Answer web services
 Google Compute Engine can be accessed via
the Developer Console, RESTful API or
Command Line Interface.

15.  Platform as a service (PaaS)
 Developing and hosting web application in
Google-managed data centers.
 App EngineApplication is easy to Build ,
maintain and Scale.
 No need to manage or maintain any servers
only upload and run.
 Automatic Scaling ,change Storage scale
automatically.

16.  Allow developer to get the advantage of
Google compute engine and storage
infrastructure.
 Load balancing.
 Support PHP, JAVA , Python and Go.
 Authentication using Google Account.
