Why Cloud?

Cloud computing is a low-cost solution.

Cloud computing offers responsiveness and flexibility.

The IT expense matches the transaction volumes.

Business users are in direct control of technology decisions.

The line between home computing applications and enterprise applications will blur.

Evolution of Cloud Computing

Evolution of Cloud Computing (cont.)

ISP 1.0 ISPs quickly proliferated to provide access to the Internet

for organizations and individuals. These early ISPs merely provided Internet connectivity for

users and small businesses, often over dial-up telephone service.

ISP2.0 ISPs consolidated and searched for other value-added

services, such as providing access to email and to servers at their facilities.

Evolution of Cloud Computing (cont.)

ISP3.0 Colocation facilities: specialized facilities for hosting

organizations’ (customers’) servers, along with the infrastructure to support them and the applications running on them.

Those facilities are “a type of data center where multiple customers locate network, server, and storage gear and interconnect to a variety of telecommunications and other network service provider(s) with a minimum of cost and complexity.”

Evolution of Cloud Computing (cont.)

ISP4.0 Application Service Providers (ASPs), focusing on a higher

value-added service of providing specialized applications for organizations, and not just the computing infrastructure.

ASPs typically owned and operated the software application(s) they provided, as well as the necessary infrastructure.

Cloud Computing (ISP5.0)

Although ASPs usually provided services to multiple customers (just as SaaS providers do today), they did so through dedicated infrastructures. Each customer had its own dedicated instance of an application, and that instance usually ran on a dedicated host or server.

The important difference between SaaS providers and ASPs is that SaaS providers offer access to applications on a shared, not dedicated, infrastructure.

Cloud Computing Defined

Properties Descriptions

Multi-tenancy (shared resources)

cloud computing is based on a business model in which resources are shared at the network level, host level, and application level.

Massive scalability

cloud computing provides the ability to scale to tens of thousands of systems, as well as the ability to massively scale bandwidth and storage space

Elasticity Users rapidly increase and decrease their computing resources as needed, as well as release resources for other uses when they are no longer required.

Pay as you go Users pay for only the resources they actually use and for only the time they require them.

Self-provisioning of resources

Users self-provision resources, such as additional systems (processing capability, software, storage) and network resources

Windows Azure

Enterprise-level on-demand capacity builder

Fabric of cycles and storage available on-request for a cost

You have to use Azure API to work with the infrastructure offered by Microsoft

Significant features: web role, worker role , blob storage, table and drive-storage

Cloud Computing

21

Amazon EC2

Amazon EC2 is one large complex web service.

EC2 provided an API for instantiating computing instances with any of the operating systems supported.

It can facilitate computations through Amazon Machine Images (AMIs) for various other models.

Signature features: S3, Cloud Management Console, Map -Reduce Cloud, Amazon Machine Image (AMI)

Excellent distribution, load balancing, cloud monitoring tools

Cloud Computing

22

Google App Engine

This is more a web interface for a development environment that offers a one stop facility for design, development and deployment Java and Python-based applications in Java, Go and Python.

Google offers the same reliability, availability and scalability at par with Google’s own applications

Interface is software programming based

Comprehensive programming platform irrespective of the size (small or large)

Signature features: templates and apps pot, excellent monitoring and management console

Barriers to Cloud Computing Adoption in the Enterprise

Security

Privacy

Connectivity and Open Access

Reliability

Interoperability

Independence from Cloud Service Providers

Economic Value

Changes in the IT Organization

IT Governance

Political Issues Due to Global Boundaries

Security Issues in Service Models

Security in SaaS Enterprises lack of

visibility about the way their data is stored and secured.

Security in IaaS IaaS only provides basic

security (perimeter firewall, load balancing, etc.)

Applications moving into the cloud will need higher levels

Security in PaaS A developer can tap to

build their applications without having any clue about what is going on underneath the service.

A hacker can leverage the PaaS cloud infrastructure for malware command and control and go behind IaaS applications.
