Cloud Computing Essay

SaaS, Software as a Service is the software, which is being deployed and provided over the Cloud environment (Grance, 2009). It represents one of the biggest Cloud markets and is growing exponentially fast (Rouse, 2016). The web is being used so that applications can be delivered, which are thoroughly managed and organized by a third party vendor and whose interface is undeniably accessed on the client’s side. The majority of the SaaS applications can be run directly from a web browser, needless of any downloads or installations. Some plugin’s requirement would be there, though. Blaming to the web delivery model, there is a well-noted eradication of the need for installation and process of application’s running on individual computers by SaaS. Some imminent examples of SaaS are: Google Apps, Salesforce, Workday, Concur, Citrix GoToMeeting, and Cisco WebEx

Customers also need take the responsibility of updating new versions and maintenances (Eamonn, 2015). The responsibility of CSPs is to provide a cloud infrastructure for customer self-service themselves, also provides training handbook or guidance for help and support.

Many companies IT department along with executives and users don’t understand the proper procedure to back up and recover their SaaS data.

Because of their background, knowledge of the billing systems and understanding of the market needs, they were well aware of the “Software As A Services (SaaS)”, its future as well as the opportunities and the obstacles. They had also envisaged the market need for an efficient billing system. Their vision was to provide an e-commerce platform that powers the service industry at a low cost

Cloud computing offers services to users based on on-demand self-service, broad network access, measured service, resource pooling and rapid elasticity; These characteristics promise a faster time for implementation, lower cost, superior scalability and a better end user satisfaction. These services are delivered in models known as Software As A service (SaaS), Platform As A Service (PAAS), and Infrastructure As A Service (IAAS). The first layer which is the Software As A service (SaaS) is the layer in which software applications are delivered to end users. Below is the Platform As A Service (PAAS) layer which offers a platform on which applications can be developed. The lowest layer is the Infrastructure As A Service (IAAS) layer, in this layer the physical servers and network infrastructure is offered as a service. These services can be deployed throughout the internet (Public Cloud Computing), on the intranet infrastructure, (Private Cloud Computing), in a shared community of private networks (Community Cloud Computing), or a hybrid of both (Hybrid Cloud Computing). The service deployment models are [8]:

Recent technological advancements have resulted in an increased number of Internet-enabled devices, such as tablets and smartphones that can connect to corporate systems.These systems may also be running anywhere, including a public software-as-a-service (SaaS) cloud, a

Software as a service (SAAS) – is a way to deliver applications via the internet as a service. Meaning, in place of installing and maintaining software on location you can access it through the internet from a third party provider. This allows independence from intricate software and hardware management as the provider manages access, security, and performance of the applications.

Cloud computing has greatly influenced many aspects within the growing technology sector. This innovative approach has altered the way many businesses and individuals use technology. While there is no one clear definition of cloud computing, the National Institute of Standards and Technology (NIST) defines cloud computing as “a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction” (Mell & Grance, 2011). It is composed of three service models: Infrastructure as a Service (IaaS,) Platform as a Service

Over the past several years the term cloud computing has become common in homes and organizations alike. Cloud computing can be defined as a pooled set of computing resources that are furnished via the internet. There are three types of cloud services typically available, these services are Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS). Organizations can benefit greatly from cloud services because they eliminate the need to buy and manage physical resources. Although such an action cuts cost it leaves organization victim to the vulnerabilities and threats that exist in cloud computing. Throughout this paper I will discuss the vulnerabilities and threats that come

SaaS applications offer wide range of configuration options and development environments that allows clients to set up their own additions and modifications.

Software as a Service (SaaS), sometimes referred to as "on- demand software" is a software delivery model in which software and associated data are hosted on the cloud. SaaS is typically accessed via a web browser and is paid on a subscription basis, monthly or yearly as per requirement.

Organisations around the world are moving steadily towards using the Software as a Service (SaaS) system for variety of tasks. It’s probably time to make sure your business is aware of the benefits of the software – your organisation will win as a result.

SaaS is becoming an increasingly prevalent delivery model as underlying technologies that support Web services and service-oriented architecture (SOA) mature and new developmental approaches, such as Ajax, become popular. SaaS is closely related to the ASP (application service provider) and On Demand Computing software delivery model
