The Resource Base Of The Saas Provider

This case gives us a fundamental understanding of the concept of cloud computing and presents the advantages and issues of this IT infrastructure. This case gives a clear vision of the company’s current situation. Three main questions to consider

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

purposes of this paper, only PaaS and SaaS will be discussed. According to the Chief

Cloud Services and Virtualization continue to grow in popularity but are they right for your business? These technologies can reduce overhead operation costs, improve utilization of resources and provide a level of flexibility to the organization’s Information Technology (IT) system. Understanding that these technologies do and their pros and cons is the foundation of choosing the right features for your business. Cloud services offer three types of services; Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) to meet the software, infrastructure needs of a business and provides them on a lease type of payment plan. Virtualization has three types of server virtualization, Full virtualization, Para-Virtualization and OS level Virtualization. Similar to Cloud services Virtualization types have features which may suit one business over another. Comparing the features provided by these technologies to total ownership of the IT system is also crucial in selecting the best services for your company as there can be an array of combinations of services contracted and internally owned features. While the perks of these technologies can be beneficial for an organization they should be carefully researched and tailored to the business strategic goals for

SaaS or Software as a Service is developing, swiftly, into the dominant delivery model to meet the requirements for organizations from SMB’s to Enterprise. Unlike purchasing on-premises software and compromising with its bugs, quirks and functionality or lack thereof, organizations are switching to cloud-based software. With the many companies offering cloud-based services from SaaS, PaaS, IaaS, etc., they expect fully functional, bug-free software to perform flawlessly, at best, or software issues that arise, rectified ASAP or they’ll switch to a competitor’s SaaS.

SaaS is a service centric software model which delivers software to the end user through the internet. Users can use the software and pay as for their usage. SaaS has been able to take advantages of the usage of centralization through a single instance and multi-tenant architecture. Therefore SaaS provides many benefits to its users such as cost saving, easy adoption, easy upgradability and etc. SaaS providers take care of maintaining and utilization of resources efficiently and they always try to meet the demands and challenges of the business world. Due to these reasons most of the conventional software have been replaced by SaaS. Although there are many advantages in using SaaS it still have some practical issues which have to be solved related to privacy and security. The SaaS vendors have to face these challenges so that they can retain their position in the business world.

There is wide range of services that could be provided by cloud providers. Based on blabla, there are 3 models of cloud services that widely popular. They are Infratructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). IaaS provides for fundamental resource for computing such as processing, servers, storage, networks and manage its physical infrastructures but costumers have control for their OS [fn1]. PaaS provides design, tools or Environment with IDE. It is usually used by software developer who wants to run their application over internet. SaaS delivers ready-use software over internet or we can called as web-based software. Cloud users neither have to maintain platform or infrastructures. These days this services gain money from advertising or user list sales for example Google mail service so users can enjoy it free.

at the innermost implementation layer, there is infrastructure-as-a-service (IaaS) model which is extended to form the platform-as-a-service (PaaS) layer by adding OS and middle¬ware support. PaaS further by applications on data, content, and meta¬data using special APIsis created to extends to the software-as-a-service (SaaS) model. all protection functions at all levels are being demanded by SaaS. At the other extreme, IaaS demands protec¬tion mainly at the networking, trusted com¬puting, and compute/storage levels, whereas PaaS embodies the IaaS support plus additional protection at the resource-management level.

Software As A Service (SAAS): is also called as "on-demand software" [2] and defined as a software distribution service in which applications and their associated data are hosted by vendors or by the cloud service providers and made available to the cloud clients over a network, typically the internet [3].SAAS provides those clients with a complete operating environment with management, user interface and applications [4]. It

Cloud computing was founded on already-existing computing technologies, such as distributed computing (Clusters, Grids), Internet technologies (Web Services, Service Oriented Architectures, Web 2.0), virtualization and systems management (autonomic computing, data centre automation) [11]. Specifically, with the advent of Cloud computing, the benefits of these technologies have been combined and further improved. Cloud basically presents a suitable environment for convenient, on-demand network access to a pool of configurable computing resources that can be mutually accessed and provisioned with insignificant administration effort or service provider interaction [1]. The optimal provisioning of these compute resources to meet certain predefined performance criteria is a complex problem which has attracted much research attention [12][13]. This problem comprise the steps involved in the allocation of suitable computing resources to tasks with the aim of optimizing certain objectives. Some objective functions include but not limited to; maximizing task throughput, minimizing the time of task completion and maximizing the utilization of resources.

Cloud computing is a wide topic and many researches are focused on improving the technology and facilitating the use of the technology. One of the concepts that have evolved to felicitate the use of the Cloud technology is the Cloud services which are offered by different Cloud providers. They are mainly grouped into three categories [10] as, Infrastructure as a Service (IaaS) provides an environment for deploying, running and managing virtual machines and storage, Platform as a Service (PaaS) provides a platform for developing other applications on top of it, Software as a Service (SaaS) provides access to complete applications as a service, such as Customer Relationship Management (CRM) [11]. Due to this diversity of cloud offerings, an important challenge for customers is to discover who the exact cloud providers that can satisfy their requirements. Often, there may be trade-offs between different functional and non-functional requirements fulfilled by different cloud providers. This makes it difficult to evaluate service levels of different Cloud providers in an objective way. Therefore, it is not sufficient to

Many years ago, to use software, businesses and organizations purchase traditionally packaged applications, such as Microsoft Office and Adobe Photoshop, and install them locally onto their computers. In the 1990’s, upon the expansion of the Internet, Application Service Provider (ASP) was introduced wherein businesses were provided with software that they can access over the Internet through a web browser. But then, service and financial failures occurred as a result of actions such as rushing the market offerings before issues were solved and failing to cut the costs for the customers at a greater extent because of having a unique server for each customer. Those scalability problems or the ability to adapt to increasing demands, and reliability problems eventually led to its downfall. Software as a Service (SaaS) or also known as “on-demand” then evolved from the ASP model. With SaaS, software is not installed in the customer’s computer but in the provider’s server somewhere else, and to access the software, the customer needs to connect to that server through either a thin client,which is a computer or a program that relies on another computer, or a web browser such as Internet Explorer, Mozilla Firefox, or Google Chrome. Basically, it is also a software delivery model. But unlike the ASP, it has increased user awareness and is a multi-tenant based service which means that repairs, updates, and upgrades are applied once for all customers instead of one at a time, making

The acceptance of Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) and the increased rate of implementation by companies across the globe has impacted internal IT / IS personnel in many ways. SaaS, PaaS and IaaS provide a virtualized infrastructure that handles computing, data storage, desktop support, networking and mobile services to meet the multiple needs of customers around the world. The other side of the equation belongs to the company looking for cloud services; it is up to their management to determine what extra steps are needed in order to meet the ever-changing information age with a growing population determined to break into everything to expose flaws, steal information or humiliate companies.

Hybrid clouds are considered a combination of public and private clouds. Companies can use third-party cloud providers either fully or partially to increase scalability and reduce equipment costs. Hybrid clouds are often used during peak times to handle workload surges which can reduce the cost since they are only being used when necessary. (Kleyman, 2013). Scenario: a company chooses to use a hybrid cloud to manage occasions where use exceeds capabilities instead of purchasing additional equipment to keep on hand for standby.

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
