CLOUD COMPUTING

INTRODUCTION
 Cloud computing is the practice of using a network of remote
servers hosted on the Internet to store, manage, and process data.
 Traditional business applications have always been very
complicated and expensive.
 Many industries and organizations have turned towards cloud
computing by 2013, cloud computing has already become a highly
demanded service and lately the cloud service providers are
experiencing a growth rate of 50% per annum.

ARCHITECTURE

ARCHITECTURAL CONSTRAINTS
 Transparency-
It is important that your CSP provides complete transparency regarding
the security they use and have in place to protect your companies’
sensitive information.
 Scalability-
This encompasses the ability to expand with additional infrastructure
resources, applications can scale up to prevent the lack of resources from
hindering performance or they can also scale down the infrastructure
statically to support a new smaller environment.
 Security-
It is the set of control-based technologies and policies designed to adhere
to regulatory compliance rules and protect information, data applications
and infrastructure associated with cloud computing use.

TYPES OF CLOUD
 Public Cloud-
It is a cloud computing model, in which a service provider makes
resources, such as virtual machines (VMs), applications or storage,
available to the public over the internet.
 Private Cloud-
It is a type of cloud computing that delivers similar advantages to
public cloud, including scalability and self-service, but through a
proprietary architecture.
 Community Cloud-
It is a cloud service model that provides a cloud computing solution to a
limited number of individuals or organizations that managed by all the
participating organizations.
 Hybrid Cloud-
It is a cloud computing environment which uses a mix of
private cloud and public cloud services with orchestration between the
two platforms.

SERVICE MODELS
 SaaS(Software as a Service)-
It is a software distribution model in which a third-party provider hosts
applications and makes them available to customers over the
Internet. Eg: google apps, microsoft office 365 (
 PaaS(Platform as a Service)-
It is a category of cloud computing that provides a platform and
environment to allow developers to build applications and services over
the internet. Eg: Windows Azure Cloud services. (
 IaaS(Infrastructure as a Service)-
It is an instant computing infrastructure, provisioned and managed over
the Internet. Quickly scale up and down with demand and pay only for
what you use. Eg: Amazon EC2, Azure platform services. (

APPLICATIONS
 Disaster recovery
 Backup
 File storage
 Test and development

DISADVANTAGES
 Downtime
 Security Issues
 Cost
Data Transfer Costs

CONCLUSION
 Cloud computing has emerged as better way of computing by
providing a range of advantages and applications.
 It is being adopted and practiced by many companies to escape
the burden of managing and storing their data.
 Despite its many advantages, it has a few setbacks.
 However, cloud computing is advancing at a fast pace and will
continue to excel among the user community.
