When a Platform-as-a-Service is demanded and the cost for purchase and operation of servers, workstations or personal computers is a challenge, single board computers may be an option to build an inexpensive system. This paper describes the lessons learned from deploying the private cloud PaaS solution AppScale on single-node systems and clusters of single board computers.

Die Nutzung von cloudbasierten Services wird als einer der Hauptbausteine der aktuellen Digitalisierungsals Industrie 4.0-Initiativen angesehen. Mittlerweile haben sich alle großen Anbieter von ITInfrastruktur-Services auch als Cloud-Anbieter positioniert. In diesem Beitrag werden die für eine Migration auf cloudbasierte Services – in ihren aktuellen Ausprägungen IaaS, PaaS und SaaS – notwendig...

Cloud Computing is a very recent term which is mainly based on distributed computing, virtualization, utility computing, networking and web and software services. This kind of service oriented architecture reduces information technology overhead for end user, total cost of ownership, supports flexibility and on-demand services. KeywordsCloud Computing, Grid Computing, IaaS, PaaS, SaaS.

Recently, cloud systems composed of heterogeneous hardware have been increased to utilize progressed hardware power. However, to program applications for heterogeneous hardware to achieve high performance needs much technical skill and is difficult for users. Therefore, to achieve high performance easily, this paper proposes a PaaS which analyzes application logics and offloads computations to ...

The poly(amidoamine)s (PAAs) ISA 1 and ISA 23 display pH-dependent conformational change and pH-dependent membrane perturbation. These properties confer potential for use as endosomolytic polymers for intracytoplasmic delivery of toxins and genes. Both polymers are relatively non-toxic, and moreover ISA 23 has the beneficial property in vivo, of being non hepatotropic when administered intraven...

Enterprises are embracing cloud computing in order to reduce costs and increase agility in their everyday business operations. Nevertheless, due mainly to confidentiality, privacy and integrity concerns, many are still reluctant to migrate their sensitive data to the cloud. In this paper, firstly, we outline the construction of a suitable Context-aware Security Model, for enhancing security in ...

Cloud Platform as a Service (PaaS) provides an environment for creating and deploying applications using one of popular development platforms. This paper presents a practical solution for building a service composition platform based on the GEMBus (GEANT Multi-domain Bus) that extends the industry accepted Enterprise Service Bus (ESB) platform with automated services composition functionality a...

Cloud computing brings advancement in the field of information technology. Cloud computing is based on several service models such as SaaS, PaaS, NaaS, DbaaS, IaaS and many more. In order to make clear the essential of cloud computing, we propose the characteristics of these service models which distinguish cloud computing from other research areas .These service models are compared from variou...
