The idea of multi-tenancy, or many tenants sharing resources, is a fundamental to cloud computing. It allows single instance of software to serve multiple organizations. SaaS requires sharing of application servers among multiple tenants for low operational costs. This paper discusses the concept of cloud computing in single tenant and multitenant environment. Multitenant applications are very useful for the increased utilization of hardware resources and improved ease of maintenance.
Keywords:Cloud computing,Multitenancy,Saas,utilization.
1.Introduction
The word cloud is used as a metaphor for the Internet, based on the standardized use of a cloud-like shape to denote a network. A cloud is a combination of hardware, networks, storage, services, and interfaces that helps in delivering computing as a service. Cloud computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. In addition, the platform provides on demand services to the users for accessing that are always on anywhere, anytime and any place. Cloud computing platform provides the scalability, availability and utility computing for services on Internet.
The cloud model comprises five essential characteristics are on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured services. It also offers main three service models such as software as a service (SaaS),platform as a service (PaaS), and infrastructure as a service (IaaS )and four deployment models are public, private, community, or hybrid. The cloud architecture must illustrate the platform and software compon...

The idea of accessing, storing, and processing data from online server or virtual server instead of local server is called as Cloud computing. When we store data in our hard disk which is very near to computer that is called as local storage and computing but Cloud computing doesn’t access data from our hard disk.
The first cloud infrastructure that I would like to describe is the Platform as a Service model, also known as PaaS. The platform in PaaS describes the fact that it provides the computers operating system and hardware for the use of applications. To expand on the platform description it easier to say that a company can use this cloud infrastructure in order to run their software rather than having to buy each computer and software to run a program for each computer. A plus side of using PaaS is that new developers are able to test applications in the cloud without crashing their own computer. It is also capable of storing information on the cloud which frees up hardware storage space. The traditional type of networking where you every computer had to be networked and hardwired to each of the
As its core essences cloud computing is nothing but a specialized form of grid computing and distributing computing’s which various in terms of infrastructure , deployment, service and Geographic’s dispersion (Veeramachanenin, Sepetember 2015) the cloud enhance scalability, collaboration, availability , ability to adapt to fluctuation according to demand accelerate development work and provide optional for cost reduction and through efficient and optimized computing. (BH kawljeet, June 2015) cloud computing (CC) recently become as a new paradigm for the delivery and hosting of services our the internet. There are mainly three service delivery model Software as Service (SaaS) required software, operating system and network is provided or we can say in SaaS the customer can access the hosted software instead of installing it in local computer and the user can access these software through local computer internet browser (e.g web enabled E-mail ) the user only pay and the cloud service provider is responsible for management or control of mobile cloud infrastructure some of the company which provide such service are Google, Microsoft , Salesforce ,Facebook, etc…..Infrastructure as Service(IaaS)the cloud provider only provide some hardware resources such as network and virtualization is
The type of structure would include allowing customers to access their accounts through online services, as well as allowing the employees to access the customers accounts from point of sale systems on the showroom floor, as well as from behind front desks. In the back, there will be the office with servers and networking implements. There will be multiple sites, all with access to the servers which contain the customers account
According to Tuncay Bayrak, in his paper, IT Support Services For Telecommuting Workforce, in new era of technology, organization faced many radical changes. The changes involved from traditional workplace into more technology ways. With the existence of various types of software that enable long-distance communication, telecommuting workforce has been evolved. Nowadays, the organization was transformed to become a network-based operating structure where employees are not tied to the workplace. Every day, the rank of telecommuter job continues to grow. Telecommuting job allows employees to work from home or remote locations across the world. The question is what is the different service support that was provided by the organization for telecommuter and traditionally employee in a regular office. The aims of this study are to explain many types of support service for telecommuting employee that can be provided and the different support service that needed for telecommuters and desktop computing. The goal of this paper is to provide a framework to help IT manager to solve the issues in increase their potential benefit of providing good support service.
Akamai Technologies, Inc. is an organization which delivers the content over the Internet. It is one of the largest organizations which provide the distributive Computing Platforms; it provides a cloud based services to the end user. It serves 30% of the overall web traffic. Akamai provided numbers of servers which are located all over the globe and stores the web application of the clients. It provides a faster access to those applications because of the distributive contents in to various servers around the world. Akamai does not want the long routes to it distributed the data based on the locations, it works as like a work or a task which is not possible to be completed by a single persons is divided in to multiple process or threats or assign to teams to complete their individual part, so that task can be complete faster, in the same way the contents are stored at different servers based on their access mechanism.
New York State Labor Law section 162 states that Reliant Software System is not obligated to provide a meal period based on the hours an employee chose to work. Reliant Software System allows their employees to make their own schedule. Based on the company's flex-time policy, the employees are to work between the hours of 8 am and 8 pm. Reliant Software System does adhere to the given law, by following the rule of giving a 20-minute compensated break if an employee works for 6 hours. But, if the employee chose to work a full day and not use the full potential of the flextime provided by the company then they are to take breaks, according to New York State Labor Law Section,162; number 3 and 4, it states," (3) Every person employed for a period or shift starting before eleven o'clock in the morning and continuing later than seven o'clock in the evening are to take an extra meal
The study of trust and control in a virtual organization has had researchers emphasizing on the importance of trust as a necessary condition for ensuring the success of these mentioned organizations (2001, p.277). Although we have been led to believe that this trust is the backbone of the virtual work environment, the author Michael Gallivan has explored the Open Source Software (OSS) movement and has made a case for the contrary. He states that “various control mechanisms can ensure the effective performance of autonomous agents who participate in virtual organizations”. He goes on to say that effective performance can be produced through control, efficiency, predictability, and calculability of processes can occur in the absence
Cloud computing is here and basically every business, corporation, or organization is using it in some form. Learning and understanding the opportunities and risks that is interlinked with this technology can be very important. Cloud computing is a model for allowing convenient, on-demand network access to a shared collection of configurable computing resources. These resources included networks, storage, applications, servers, and services. It can be quickly provisioned and distributed with insignificant effort or interaction of service provider. Characteristics of cloud computing include rapid elasticity, broad network access, on demand self-service, measured service, and resource pooling.

They use algorithms on this data (Gigabytes to Terabytes) to segment the customers. It’s very important to get the result without any delays or they will lose their customers. So they implemented their solution using cloud computing. They chose Amazon EC2 which cloud computing service that allows users or organizati...
Cloud storage basic terms, is a way to save information to the web that can managed data storage. Cloud computing services are online services, which store this information to a safe and secure location online. It’s offered a quicker, easier and safer backup than conventional methods of file storage such as bookshelves or cardboard files.
The main driving forces of cloud data storage are reputable companies such as Amazon and Google building comprehensive computing infrastructures (Google, 2009). These infrastructures are removing the complexity of in-house data storage and ultimately reducing costs of limited networked data centres (Hitachi, 2010). The traditional inefficient model of purchasing servers every time you need to accommodate for high use or growth is now being replaced by internet based systems that replicate your data centres but without the big overheads (Google, 2009). This flexibility assists in the ever changing business world and its continuous improvement initiatives to remove waste, improve efficiency, and ultimately reduce costs. Another key driving force is the support for effective business continuity which will remove again the hardware costs and the strain on risk assessment and management. Removing this hassle can free up valuable time for the Chief Information Officer (CIO) and the Information Technology (IT) department to implement IT and Information Management (IM) efficiently and in due course reduce cost. Werner Vogles of Amazon of Web Services (Twitter) supports the idea of less hardware because if you have to buy more hardware to initiate this cloud movement it is not a cloud. This further supports the need to shed the old procedures of having in-house hardware and data storage and instil efficacy.
Cloud computing is the transfer of computing data or information into Internet. Cloud computing services allows individuals and businesses to
Cloud computing remains firm and has great potential for the future despite its disadvantages and the fact that it is still is a working progress. The number of users are constantly growing and bigger companies are starting to be interested, offering better and finer tuned services and solutions. The best thing to do is to hope that the advantages will further grow and flourish and the disadvantages will slowly disappear, since cloud computing seems to have made IT a little bit easier (Morris, 2011).
In cloud computing, the word cloud is used as a metaphor for “the internet”. So the cloud computing means “a type of internet-based computing”, where different services such as servers, storage and applications are delivered to an organization’s computers and devices through the internet.
