Definition of Cloud ComputingComputing and software resources that are delivered on

demand, as service.(2013, January) A Walk in the Clouds. Cloud Computing, CDW-G Reference Guide., 3-5.

The cloud is actually a bunch of computer servers that store and transmit data These servers are very large and can hold massive amounts of data The servers can be housed any where in the world the user accesses the data by log-in from any where

Cloud service model

What is Software as a Service? (SaaS)

• SaaS is a software delivery methodology that provides licensed multi-tenant access to software and its functions remotely as a Web-based service.

Infrastructure as a Service (IaaS)

• IaaS is the delivery of technology infrastructure on demand scalable service

Platform as a Service (PaaS)

• PaaS provides all of the facilities required to support the complete life cycle of building and delivering web applications and services entirely from the Internet.

Cloud Deployment Models

Private cloud : is cloud infrastructure operated solely for asingle organization, whether managed internally orexternally . these service use storage capacity and processorpower that is not owned by the organization or business .

Public cloud : is a style of computing where scalable and elasticIT-enabled capabilities are provided as a service to externalcustomers using Internet technologies—i.e., public cloudcomputing uses cloud computing technologies to supportcustomers that are external to the provider’s organization

Cloud Deployment Models

Private cloud + Public cloud = HYBRID CLOUD

Hybrid cloud :

Hybrid cloud is a composition of two or more clouds

(private, community or public) that remain distinct

entities but are bound together, offering the benefits of

multiple deployment models. Hybrid cloud can also

mean the ability to connect collocation, managed and

dedicated services with cloud resources

Enterprise Cloud Solutions

1. Hybrid Cloud

– Scalability of the Public Cloud with the control and security of a private cloud

2. Disaster Recovery

– Keep images of your servers on cloud infrastructure ready to go in case of a disaster

3. Cloud File Storage

– Backup or Archive your company data to cloud file storage

4. Load Balancing

– Use cloud infrastructure for overflow management during peak usage times

Enterprise Cloud Solutions (cont)

5 . Overhead Control– Lower overhead costs and make your bids more

competitive

6 . Distributed Network Control and Cost Reporting– Create an individual private networks for each of

your subsidiaries or contracts

7 . Rapid Deployment– Turn up servers immediately to fulfill project

timelines

CLOUD MIGRATION

Cloud migration is the process of moving data,applications or other business elementsfrom an organization's onsite computers tothe cloud, or moving them from one cloudenvironment to another.

Concluding Remarks 1

• Cloud computing stimulates new research directions for new and novel ways of developing software & services

• Proper planning and migration services are needed to ensure a successful implementation

• Public and Private Clouds can be deployed together to leverage the best of both

Concluding Remarks 2

• Testing as a Service (TaaS) has a huge potential for Software Engineering in general and GSE in particular

• need for process and tool support for migration and/or upgrade of applications and tools for cloud computing model
