Download or read book Toward Customizable Multi tenant SaaS Applications written by Xin Sun and published by . This book was released on 2016 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, Computing is so pervasive that it has become indeed the 5th utility (after water, electricity, gas, telephony) as Leonard Kleinrock once envisioned. Evolved from utility computing, cloud computing has emerged as a computing infrastructure that enables rapid delivery of computing resources as a utility in a dynamically scalable, virtualized manner. However, the current industrial cloud computing implementations promote segregation among different cloud providers, which leads to user lockdown because of prohibitive migration cost. On the other hand, Service-Orented Computing (SOC) including service-oriented architecture (SOA) and Web Services (WS) promote standardization and openness with its enabling standards and communication protocols. This thesis proposes a Service-Oriented Cloud Computing Architecture by combining the best attributes of the two paradigms to promote an open, interoperable environment for cloud computing development. Mutil-tenancy SaaS applicantions built on top of SOCCA have more flexibility and are not locked down by a certain platform. Tenants residing on a multi-tenant application appear to be the sole owner of the application and not aware of the existence of others. A multi-tenant SaaS application accommodates each tenants unique requirements by allowing tenant-level customization. A complex SaaS application that supports hundreds, even thousands of tenants could have hundreds of customization points with each of them providing multiple options, and this could result in a huge number of ways to customize the application. This dissertation also proposes innovative customization approaches, which studies similar tenants customization choices and each individual users behaviors, then provides guided semi-automated customization process for the future tenants. A semi-automated customization process could enable tenants to quickly implement the customization that best suits their business needs.

Available in PDF, EPUB and Kindle. Book excerpt: Cloud computing has received significant attention recently as it is a new computing infrastructure to enable rapid delivery of computing resources as a utility in a dynamic, scalable, and visualized manner. SaaS (Software-as-a-Service) provide a now paradigm in cloud computing, which goal is to provide an effective and intelligent way to support end users' on-demand requirements to computing resources, including maturity levels of customizable, multi-tenancy and scalability. To meet requirements of on-demand, my thesis discusses several critical research problems and proposed solutions using real application scenarios. Service providers receive multiple requests from customers, how to prioritize those service requests to maximize the business values is one of the most important issues in cloud. An innovative prioritization model is proposed, which uses different types of information, including customer, service, environment and workflow information to optimize the performance of the system. To provide "on-demand" services, an accurate demand prediction and provision become critical for the successful of the cloud computing. An effective demand prediction model is proposed, and applied to a real mortgage application. To support SaaS customization and fulfill the various functional and quality requirements of individual tenants, a unified and innovative multi-layered customization framework is proposed to support and manage the variability of SaaS applications. To support scalable SaaS, a hybrid database design to support SaaS customization with two-layer database partitioning is proposed. To support secure SaaS, O-RBAC, an ontology based RBAC (Role based Access Control) model is used for Multi-Tenancy Architecture in clouds. To support a significant number of tenants, an easy to use SaaS construction framework is proposed. As a summary, this thesis discusses the most important research problems in cloud computing, towards effective and intelligent SaaS. The research in this thesis is critical to the development of cloud computing and provides fundamental solutions to those problems.

Download or read book Microservices written by Antonio Bucchiarone and published by Springer Nature. This book was released on 2019-12-11 with total page 364 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes in contributions by scientists and practitioners the development of scientific concepts, technologies, engineering techniques and tools for a service-based society. The focus is on microservices, i.e cohesive, independent processes deployed in isolation and equipped with dedicated memory persistence tools, which interact via messages. The book is structured in six parts. Part 1 “Opening” analyzes the new (and old) challenges including service design and specification, data integrity, and consistency management and provides the introductory information needed to successfully digest the remaining parts. Part 2 “Migration” discusses the issue of migration from monoliths to microservices and their loosely coupled architecture. Part 3 “Modeling” introduces a catalog and a taxonomy of the most common microservices anti-patterns and identifies common problems. It also explains the concept of RESTful conversations and presents insights from studying and developing two further modeling approaches. Next , Part 4 is dedicated to various aspects of “Development and Deployment”. Part 5 then covers “Applications” of microservices, presenting case studies from Industry 4.0, Netflix, and customized SaaS examples. Eventually, Part 6 focuses on “Education” and reports on experiences made in special programs, both at academic level as a master program course and for practitioners in an industrial training. As only a joint effort between academia and industry can lead to the release of modern paradigm-based programming languages, and subsequently to the deployment of robust and scalable software systems, the book mainly targets researchers in academia and industry who develop tools and applications for microservices.

Download or read book Developing Multi Tenant Applications for the Cloud on Windows Azure written by Dominic Betts and published by Microsoft patterns & practices. This book was released on 2013-03 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can you create an application that has truly global reach, and can scale rapidly to meet sudden massive spikes in demand? Historically, companies had to invest in an infrastructure capable of supporting such an application themselves, and plan for peak demand-which often means that much of the capacity sits idle for much of the time. Typically, only large companies would have the available resources to risk such an enterprise. The cloud has changed the rules of the game. By making infrastructure available on a "pay as you go" basis, creating a massively scalable, global application is within the reach of both large and small companies. Yes, by moving applications to the cloud you're giving up some control and autonomy, but you're also going to benefit from reduced costs, increased flexibility, and scalable computation and storage. This guide is the third release of the second volume in a series about Windows Azure. It demonstrates how you can create from scratch a multi-tenant, Software as a Service (SaaS) application to run in the cloud by using the Windows Azure tools and the increasing range of capabilities of Windows Azure. The guide focuses on both good practice design and the practicalities of implementation for multi-tenant applications, but also contains a wealth of information on factors such as security, scalability, availability, and elasticity that are relevant to all types of cloud hosted applications. The guide is intended for any architect, developer, or information technology (IT) professional who designs, builds, or operates applications and services that run on or interact with the cloud. Although applications do not need to be based on the Windows operating system to work in Windows Azure, or be written using a .NET language, this guide is written for people who work with Windows based systems. You should be familiar with the .NET Framework, Visual Studio, ASP.NET MVC, and Visual C#.
Download or read book Lower Case Sigma OS written by Ariel Szekely and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the enormous success of cloud computing, programming and deploying cloud applications remains challenging. Application developers are forced to either explicitly provision resources or limit the types of applications they write to fit a serverless framework such as AWS Lambda. [lower case sigma]OS is a new multi-tenant cloud operating system that allows providers to manage resources for tenants while simplifying application development. A key contribution of [lower case sigma]OS is its novel abstraction: realms. Realms present tenants with the illusion of a single-system image and abstract boundaries between physical machines. Developers structure their applications as processes, called procs in [lower case sigma]OS. Much like a time-sharing OS multiplexes users' processes across a machine's cores, [lower case sigma]OS multiplexes tenants' procs across the cloud provider's physical machines. Since each tenant tends to plan for peak load, realms can improve data center utilization by enabling providers to transparently reallocate partial machines to another tenant's realm when load dips. An evaluation of [lower case sigma]OS demonstrates that a [lower case sigma]OS-based MapReduce ([lower case sigma]OS-MR) implementation grows quickly from 1 core to 32 and scales near-perfectly achieving 15.26x speedup over the same implementation running on 2 cores. Similarly, an elastic Key-Value service built on [lower case sigma]OS ([lower case sigma]OS-KV) cooperates with [lower case sigma]OS to scale the number of kvd servers and balance shards across them, according to client load. [lower case sigma]OS also achieves high resource utilization when multiple tenants' realms compete for a shared group of machines. For example, when [lower case sigma]OS multiplexes a long-running [lower case sigma]OS-MR job in one realm and a [lower case sigma]OS-KV service with varying numbers of clients in another realm, [lower case sigma]OS keeps utilization above 90% and transparently moves partial machines between the realms as the [lower case sigma]OS-KV client load changes.

Download or read book Towards Application centric Fairness in Multi tenant Clouds with Adaptive Cpu Sharing written by Anthony Ojo Ayodele and published by . This book was released on 2016 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ongoing rush for cloud-based services by small, medium, and large-scale organizations in other to reduce operational cost overhead, and have more flexibility in the deployment of business applications continues unabated. Cloud computing environment allows sharing of configurable computing resources (e.g., CPU, memory, networks, servers, storage, applications, and services) among cloud tenants. Thus, the cloud computing environments has significantly simplified the capacity provisioning process to support massive migration of enterprise applications to the cloud. However, there exist several challenges facing cloud services that are preventing cloud subscribers; individuals, private, and public organizations from achieving total satisfaction. These challenges include CPU sharing, contention for hardware, and lack of fairness in re source management. This dissertation aims at supporting ongoing research efforts in academia and private industry in addressing these challenges. The contributions of this dissertation start with measurement and interference profiling of application performance i n multi-tenant cloud environment. Through series of quantitative and qualitative experimental research methods in public and private clouds, this dissertation reveals how an imbalance in the allocation of shared cloud computing resources affect in-cloud application performance. The dissertation examined the complex interplay among cloud tenants as they compete for CPU time, and shared hardware resources by identifying the relationship between low-level CPU multiplexing and high-level application performance in multi-tenant cloud. The dissertation continues by establishing a unique linear mathematical relationship between CPU steal time an d overall application performance. Our approach is to monitor the progress of submitted applications at runtime, tracks the slowdown of individual application and applies adjustment until convergence. Thus, when an application suffered more slowdown, we allocate more CPU to reduce unfairness. In establishing system support for fine-grained profiling, we report system level actvities at sub-second granularity. We predicted application performance degradation by creating a mathematical relationship between high-level application performance and low-level machine event s (i.e., CPU steal time and Misses per thousand instructions). We validate the added value of our approach by comparing application performance slowdowns (average) with various datasets. Based on our experimental results , our approach helps mitigate co-tenant interference and reduces unfairness by minimizing the overall application slowdowns. Lastly, the dissertation concludes by proposing Adaptive CPU Sharing (ACS) in multi-tenants’ clouds. ACS leverages the Xen CPU scheduler capability to reduce unfairness in resource sharing among cloud tenants and reduce application performance degradation.
