The document discusses cloud architecture and describes the different layers of cloud computing including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). It explains how virtualization allows for the pooling of computing resources and rapid provisioning of these resources. The document also discusses multi-tenancy and how a single software instance can be configured for multiple tenants' needs in a SaaS environment. As an example, it describes how a payroll processing application currently used by multiple government departments could be migrated to a cloud environment for improved maintenance and reduced costs.

Amazon Web Services (AWS) provides on-demand computing resources and services in the cloud, with pay-as-you-go pricing. This session provides an overview and describes how using AWS resources instead of your own is like purchasing electricity from a power company instead of running your own generator. Using AWS resources provides many of the same benefits as a public utility: Capacity exactly matches your need, you pay only for what you use, economies of scale result in lower costs, and the service is provided by a vendor experienced in running large-scale networks. A high-level overview of AWS infrastructure (such as AWS Regions and Availability Zones) and AWS services is provided as part of this session.

Cloud computing is a releasing individual and institutions from the traditional cvcle of buying-using-maintaining-upgrading IT resourcs - both hardware and software. Instead it is making IT resource accessible from anywhere and at proportions as required by the end user. Here is a brief introduction to this new transformation
Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, on-demand access to a shared pool of configurable computing resources (e.g., computer networks, servers, storage, applications and services),
Azure was announced in October 2008 and released on 1 February 2010 as Windows Azure, before being renamed to Microsoft Azure on 25 March 2014. Along with Amazon Web Services Azure is considered a leader in the IAAS field.
Microsoft Azure is an open and flexible cloud platform that enables you to quickly build, deploy, and manage applications across a global network of Microsoft-managed datacenters. You can build applications using any language, tool, or framework. And you can integrate your public cloud applications with your existing IT environment.
This definition tells us that Microsoft Azure is a cloud platform, which means you can use it for running your business applications, services, and workloads in the cloud. But it also includes some key words that tell us even more:
Open Microsoft Azure provides a set of cloud services that allow you to build and deploy cloud-based applications using almost any programming language, framework, or tool.
Flexible Microsoft Azure provides a wide range of cloud services that can let you do everything from hosting your company’s website to running big SQL databases in the cloud. It also includes different features that can help deliver high performance and low latency for cloud-based applications.
Microsoft-managed Microsoft Azure services are currently hosted in several datacenters spread across the United States, Europe, and Asia. These datacenters are managed by Microsoft and provide expert global support on a 24x7x365 basis.
Compatible Cloud applications running on Microsoft Azure can easily be integrated with on-premises IT environments that utilize the Microsoft Windows Server platform.
It provides both PAAS and IAAS services and supports many different programming languages, tools and frameworks, including both Microsoft-specific and third-party software and systems.

It will focus on how security problems can be addressed. The paper is divided into four parts. The first part will pinpoint the criteria of using electronic voting systems while focusing on the main security problems in DRE and Internet based voting systems and will suggest their solutions. The second and third parts will propose secure reference architecture for electronic and internet based voting systems while the last part will be the conclusion.
The cloud computing paradigm is still evolving, but has recently gained tremendous momentum. However, security and privacy issues pose as the key roadblock to its fast adoption. In this paper we present security and privacy challenges that are exacerbated by the unique aspects of clouds and show how they're related to various delivery and deployment models. We discuss various approaches to address these challenges, existing solutions, and future work needed to provide a trustworthy cloud computing environment.
Proposed pricing model for cloud computingAdeel Javaid
Cloud computing is an emerging technology of business computing and it is becoming a development trend. The process of entering into the cloud is generally in the form of queue, so that each user needs to wait until the current user is being served. In the system, each Cloud Computing User (CCU) requests Cloud Computing Service Provider (CCSP) to use the resources, if CCU(cloud computing user) finds that the server is busy then the user has to wait till the current user completes the job which leads to more queue length and increased waiting time. So to solve this problem, it is the work of CCSP’s to provide service to users with less waiting time otherwise there is a chance that the user might be leaving from queue. CCSP’s can use multiple servers for reducing queue length and waiting time. In this paper, we have shown how the multiple servers can reduce the mean queue length and waiting time. Our approach is to treat a multiserver system as an M/M/m queuing model, such that a profit maximization model could be worked out.
Wireless Sensor Networks (WSNs) are distributed and independent sensors that are connected and worked together to measure quantities such as temperature, humidity, pressure, noise levels or vibrations. WSNs can measure vehicular movement (velocity, location, etc.) and monitor conditions such as lightning condition, soil makeup and motion. Nowadays, WSNs are utilized in many common applications such as vehicle applications. Some of vehicle applications are: vehicle tracking and detection, tire pressure monitoring, vehicle speed detection, vehicle direction indicator, traffic control, reversing aid sensors etc. Such applications can be divided in major categories such as safety, security, environment and logistics. To implement WSN in an application and have an efficient system, we need to consider about WSN technology, and its components. This paper is aimed at providing reliable software architecture of WSN that could be implemented for better performance and working.

2. IntroductionIntroduction
High performance networks and advanced
development of internet is the basis for cloud
computing .
Cloud computing has started taking shape
incorporating virtualization and on demand
deployment and internet delivery of services.
3. Cloud is a pool of virtualized computer
resources networked, which can:
Host a variety of workloads.
Batch-style back-end jobs.
Interactive user-facing applications.
Workloads can be deployed and scaled out quickly
through the rapid provisioning of virtual machines or
physical machines.
Support redundant, self recovering, highly scalable
programming models that allow workloads to recover
from many unavoidable hardware / software failures.
Monitor resource use in real time to enable
rebalancing of allocations when needed.

12. MULTI-TENANCYMULTI-TENANCY
Multi-tenancy is an architectural pattern
A single instance of the software is run on the service
provider’s infrastructure
Multiple tenants access the same instance.
In contrast to the multi-user model, multi-tenancy
requires customizing the single instance according to
the multi-faceted requirements of many tenants.
13. A Multi-tenants application lets customers (tenants)
share the same hardware resources, by offering them
one shared application and database instance ,while
allowing them to configure the application to fit there
needs as if it runs on dedicated environment.
These definition focus on what we believe to be the key
aspects of multi tenancy:
1.The ability of the application to share hardware
resources.
2.The offering of a high degree of configurability of the
software.
3.The architectural approach in which the tenants make
use of a single application and database instance.

25. Background of the ApplicationBackground of the Application
The existing application, which is implemented in state
government departments, is having the following main
sections:
Data admin
Master data entry
Month process
Token no. entry
Reports
Back up to system
The existing package is deployed in the user premises and
found difficult in regular software maintenance and
overhead costs for the infrastructure requirements.
26. The application is ideally suited to deploy in cloud
environment with following features:
The application can be taken up as a single instance and multi-
tenant model
Configurability option in the software is required to be provided.
Configurability in SaaS enables the flexibility to access the software
by many tenants with the option of configuring each tenant for
their application needs.
