Molntjänster och molnleverantörer : En uppsats om leverantörsinlåsningarHajdarevic, Demir, Frimanson, Per January 2014 (has links)
Det finns många fördelar med att använda molntjänster och molnmarknaden har växt fort de senaste åren. Men när molnleverantörsmarknaden är så pass konkurrens utsatt är det inte lätt att välja vem man vill vända sig till, och det finns ofta anledningar till att vilja byta leverantör. Det finns många saker som kan låsa in en kund hos en leverantör, ofta på grund av att det skulle bli alldeles för dyrt att flytta, kanske för att ditt system inte är kompatibelt med någon annan leverantör, eller för att ett avtal hindrar dig från att flytta delar av systemet. Detta är vad man brukar kalla för leverantörsinlåsningar (vendor lock-ins). Många vill idag flytta system till molnet, men få är tillräckligt kunniga i vad det innebär och vad som kommer krävas från kunden. I den här studien vill vi belysa problemet och erbjuda vägledning till hur man kan minimera leverantörsinlåsningar.

Informační systémy v éře cloud computingu / Information Systems in a Cloud Computing eraKlimt, Roman January 2011 (has links)
This thesis is focused on cloud computing and its impact on enterprise resource planning information systems. The historical background of cloud computing is discussed in the first of the thesis. After that, analysis of all possible services and types of cloud computing are provided. In this first part of this thesis, there is also an analysis of cloud computing providers who provide one of the possible cloud computing service - Infrastructure as a Service(IaaS). This thesis evaluates IaaS providers based on suggested methodology. According to this methodology each provider is ranked and the provider with the highest score is used as a provider for outsourcing infrastructure for a new model of information system which is suggested further in the thesis. The next part of this thesis provides a detailed view on cloud computing service closely related to software distribution - Software as a Service(SaaS). This focuses on key features of this approach, there is a discussion about differences between ASP and on-premis approach. At the end of this part there is a detailed discussion about SaaS benefits and risks for customers as well as software vendors. Having discussed all necessary theoretical background a local software company providing mainly on-premise enterprise resource planning information system is described. After all threads and opportunities of this company are analyzed it is suggested to provide a new option of distributing one of its information system to customers - in the form of SaaS. Based on the decision in the previous part, one of the information systems offered to customers is chosen and reengineered in order to allow distribution over the Internet as SaaS. While changing the architecture of the information system, the main focus is to reduce initial costs. A necessary features which need to be changed are analyzed from three perspectives - technological, process and economical. In all of these perspectives there is a discussion about problems which need to be kept in mind. Each problem is analyzed and the solution options are discussed. Towards the end of each problematical part there is a recommendation for the company in order to reach the set goals. The final part is comparing the on-premise system and the SaaS system. The comparison is provided in the customer example. There are calculations for each solution and a discussion about potential attractiveness of a newly designed information system for potential customers.

Efficient parallel installation of software collections on a PaaSBoraie, Alexander January 2021 (has links)
This master thesis analyses and investigates how to speed up the deployment of a suite of services to a Platform as a Service. The project use IBM’s Cloud Pak for Applications together with Red Hats OpenShift to provide insights on important factors that influences the deployment process. In this thesis, a modification was done on the installer such that the deployment instructions were sent in parallel instead of sequentially. Except for the parallel suggestion, this thesis also investigates different options on how constraints could be applied to the CPU and what the consequences are. At the end of this report, the reader will also see how the deployment times are affected by cluster scaling. An implementation of the parallel deployment showed that the installation time of Cloud Pak for Applications could be decreased. It was also shown that the CPU was not utilized fully and that there exists significant CPU saturation during the deployment. The evaluation of the scaling analysis showed that, in regards of this thesis, it is more beneficial both timewise and cost-wise to scale horizontally rather than vertically.

KTHFS Orchestration : PaaS orchestration for HadoopLorente Leal, Alberto January 2013 (has links)
Platform as a Service (PaaS) has produced a huge impact on how we can offer easy and scalable software that adapts to the needs of the users. This has allowed the possibility of systems being capable to easily configure themselves upon the demand of the customers. Based on these features, a large interest has emerged to try and offer virtualized Hadoop solutions based on Infrastructure as a Service (IaaS) architectures in order to easily deploy completely functional Hadoop clusters in platforms like Amazon EC2 or OpenStack. Throughout the thesis work, it was studied the possibility of enhancing the capabilities of KTHFS, a modified Hadoop platform in development; to allow automatic configuration of a whole functional cluster on IaaS platforms. In order to achieve this, we will study different proposals of similar PaaS platforms from companies like VMWare or Amazon EC2 and analyze existing node orchestration techniques to configure nodes in cloud providers like Amazon or Openstack and later on automatize this process. This will be the starting point for this work, which will lead to the development of our own orchestration language for KTHFS and two artifacts (i) a simple Web Portal to launch the KTHFS Dashboard in the supported IaaS platforms, (ii) an integrated component in the Dashboard in charge of analyzing a cluster definition file, and initializing the configuration and deployment of a cluster using Chef. Lastly, we discover new issues related to scalability and performance when integrating the new components to the Dashboard. This will force us to analyze solutions in order to optimize the performance of our deployment architecture. This will allow us to reduce the deployment time by introducing a few modifications in the architecture. Finally, we will conclude with some few words about the on-going and future work.
