In today's competitive business environment, information systems are not a luxury; rather they are vital for survival. A new generation of ISs has been established on cloud capabilities. Moving toward software as a service is not the goal in a business, and if not implemented properly, competitive advantage may even suffer. Managers and change agents should undertake deep study over SaaS implementation before migration. In this chapter, the main elements and features in which CEOs and IT managers should consider in evaluating the SaaS migration option will be provided, and enterprises may be acquainted with the concept, goals, and theoretical foundations of SaaS as a main cloud-based service in the business environment. On the other hand, businesses should undertake some necessary changes in the operating circumstances which are utilization of a proper and modified business models established over a knowledge base strategic movement. This will lead enterprises to achieve the main goals of migrating to SaaS and cloud platforms (i.e., agility, competitive advantage, and innovation).

SaaS is software as a service. In previous days when the concept of providing the facility of distributed system from where information can be shared was introduced then the concept of Application service provider came into the picture. The idea was to provide application-based services to the companies using client server techniques. It became popular. SaaS is introduced to provide software also as a service which is upgraded version of the ASP. In this paper SaaS will be discussed in detail. There are two main types of SaaS. The challenges in implementation of SaaS will also be discussed.

Abstract: No matter whatever that you may sell, managing your customers is important for the success of your business. This is where exactly choosing a CRM (Customer Relationship Management) comes into play. Choosing the best CRM system for your organization requires identifying your objectives and determining the main customer management problems that you need to resolve by adopting a CRM for your businesses. When looking for CRM (Customer Relationship Management) or ERP (Enterprise Resource Planning) software, you will find that there are different ways of implementation, including onpremise and SaaS aka software as a service. Both types can help take your business to new heights, but it is up to you to decide which type works best for you. So in this paper we are going to compare on-premise and SaaS CRM and will also look at the challenges faced by SaaS CRM. Keywords: CRM, On-Premise, SaaS, Cloud Computing, Cloud Services.

The online sales of tourism activities are increasing despite once-sluggish growth, especially in contrast to other tourism segments, i.e., transportation and accommodation, which already had a more significant share of online sales. This article aims to provide a narrative as to why tourism activities took longer than other travel segments to be sold online and why the trend of being sold increasingly online will continue into the future. The article concludes that two key factors, the nature of tourism activities (i.e., subjective and customizable) and technological advancements, have contributed to this trend. These technological advancements include tourism activity booking software-as-a-service (SaaS), innovation in payments technology, application programming interfaces (APIs), big data, and dynamic packaging. Additionally, the COVID-19 pandemic further accelerated this trend.

Various industrial and business sectors use Software-as-a-Service due to its fast services. However, Software-as-a-Service providers face various challenges in providing high-quality services while simultaneously managing vast multi-tenant infrastructure models and increasingly complex user requirements. To address these problems, we identified those factors that affect the quality of Software-as-a-Service from the perspective of provider–user relationship and investigated how service providers can objectively improve user satisfaction. In a case study, we evaluated the perceived service quality of an information system in the public sector based on user satisfaction with the quality of external outsourcing service in terms of assurance, empathy, responsiveness, reliability, and communication. We identified new sub factors (commitment, skills, effectiveness, change management, business processes, and motivation) and proposed action steps that can guide best practices in ensuring Software-as-a-Service quality. These factors are greatly influenced by the communication between providers and users.

The majority of cloud applications are created or delivered to provide users with access to system resources or prebuilt processing algorithms for efficient data storage, management, and production. The number of cases linking cloud computing to the use of global observation satellite data continues to rise, owing to the benefits of cloud computing. This study aims to develop a cloud software as a service (SaaS) that yields reflectance products in high-resolution Korea Multi-Purpose Satellite (KOMPSAT)-3/3A satellite images. The SaaS model was designed as three subsystems: a Calibration Processing System (CPS), a Request System for CPS supporting RESTful application programming interface (API), and a Web Interface Application System. Open-source components, libraries, and frameworks were used in this study’s SaaS, including an OpenStack for infrastructure as a service. An absolute atmospheric correction scheme based on a Second Simulation of a Satellite Signal in the Solar Spectrum (6S) radiative transfer code with atmospheric variable inputs was used to generate the top-of-atmosphere (TOA) and top-of-canopy (TOC) reflectance products. The SaaS implemented in this study provides users with the absolute atmospheric calibration functionality to apply their KOMPSAT-3/3A satellite image set through a web browser and obtain output directly from this service. According to experiments to check the total performance time for images, bundled with four bands of red, green, blue, and near-infrared, it took approximately 4.88 min on average for the execution time to obtain all reflectance results since satellite images were registered into the SaaS. The SaaS model proposed and implemented in this study can be used as a reference model for the production system to generate reflectance products from other optical sensor images. In the future, SaaS, which offers professional analysis functions based on open source, is expected to grow and expand into new application fields for public users and communities.
