Running a WordPress-based Backup of your Blog in the RHCloud

The OpenShift-based RH-Cloud offers a whole variety of free services as part of the RHCloud community program. Among this list is cloud-based WordPress hosting.

After playing around for a while I was asking myself if it would be possible to run a backup of this blog (tmb.nginet.de) in the RHCloud. Idea was to instantiate a WordPress instance in the cloud and to automatically push content from this, my original blog (hosted by www.strato.de, for way too poor value-for-money, classic-lock-in) to the RHCloud-based clone whenever a new post comes up.

Installing the WordPress instance on top of the RHCloud services is trivial; it took less than 5m, most of which was required to find a proper name for the blog (blog-tmbohnert.rhcloud.com). It’s a true one-click-wordpress experience.

Another 5m later, the existing content was exported from tmb.nginet.de and imported to blog-tmbohnert.rhcloud.com, using the standard WP export/import plugin.

In order to push content automatically from the RHCloud-based WP-instance a content push plugin seemed to be the proper tool. There are quite a few of them available. A choice had to be made, between the  NextScripts Social Networks Auto-Poster and Push-Syndication Plugins. Eventually, the former seemed to be the one powerful and at the same time more intuitive to use.

Conclusion. It took ~30m, from account registration, WP-installation, content export-import, plugin installation and configuration over writing of this post to  have a fully-functional WP-clone in the RHCloud.



EUCNC 2014 workshop: Mobile Cloud Infrastructures and Services (MCIS)

Workshop Motivation and Background

This workshop addresses the three main topics that are significant for the realization of the Future Internet Architecture, which are the Mobile Networking, Network Function Virtualization and Service Virtualization.

While mobile communication networks have been established decades ago and are still continuously evolving, cloud computing and cloud services became a hot topic in recent years and is expected to have significant impact on novel applications as well as on ICT infrastructures. Cloud computing and mobile communication networks have been considered separate from each other in the past. However, there are various possible synergies between them. This trend supports the use of cloud computing infrastructures as processing platforms for signal and protocol processing of mobile communication networks, in particular for current (4G) and future (5G) generation networks. This enables several opportunities to optimize performance of cloud applications and services observed by mobile users, whose devices are connected to the cloud via wireless access networks. This trend is also in line with the emerging ETSI activities in Network Functions Virtualization (NFV). The “Mobile Cloud Infrastructures and Services” workshop focuses on the thematic area that the EU project MCN is concentrating on and is addressing emerging technologies in cloud services and mobile communication infrastructures. Emphasis will be put on possible integration scenarios and synergies between them.

Workshop Structure
Based on the successful format of the FUNEMS 2013, “Mobile Cloud Networking and Edge ICT “ workshop, we plan to have a good mix of invited keynote talks from key participants in the EU FP7 projects MCN, iJOIN, CONENT and FLAMINGO and peer-reviewed abstracts of the papers to be presented. Moreover, the panel organized in 2013 was highly appreciated by the participants and therefore is proposed to be part of the program in 2014. The speakers of the workshop will form the panel. During the panel session, the presented papers will be used as the starting point for the panel discussions. The programme associated with this workshop is as follows:

Previous Editions

The previous edition of this workshop was entitled: “Mobile Cloud Networking and Edge ICT Services”, and it has been organized during the FUNEMS 2013, http://www.futurenetworksummit.eu/2013/. The duration of the workshop was half a day and has been organised in two sessions. The current edition of this workshop will focus mainly only on one of these sessions, “Mobile Cloud Infrastructures and Services”. The workshop was successful and attracted a relatively high number of attendees compared to other parallel workshops. 25- 50 participants have been permanently in the room at the Mobile Cloud Networking and Edge ICT Services 2013.

Workshop Audience

The target audience will be the telecommunication infrastructures and cloud computing research and industry communities, with an emphasis on European FP7 project involved researchers and organizations. The workshop organizers are participating among others in the EU FP7 IP projects: Mobile Cloud Networking (MCN), CONTENT, iJOIN, FLAMINGO and in Standardization Bodies such as Open Networking Foundation and ETSI NFV (Network Function Virtualisation). It is therefore expected that a significant part of the audience and participants will be the communities involved in Standardization Bodies such as Open Networking Foundation and ETSI NFV and the EU FP7 projects that are and will be cooperating with the EU FP7 IP project “Mobile Cloud Networking” (MCN).

Mobile Cloud Networks
Thursday, 21 November 2013, 16:15 – 17:45, Jupiter 9

Innovative services and products over the next decade will be strongly driven by cloud computing technologies. Research communities on cloud technologies will need to address challenges such as radio access in the cloud, new opportunities for sharing of infrastructure, open source, SDN (software defined networks), new CDN (content delivery networks), and ICN (information centric networks). Globally, green requirements, performance and scalability studies and related impacts on policy, regulation and standardisation will also need to be addressed. Telecommunication networks need to be prepared for the requirements coming from cloud services, transporting the corresponding information in an effective and efficient way. The cloud concept is being brought into network architectures, by introducing virtualisation into all signal processing and information storage in the networks, and the service provision concept as a replacement for current network node functionalities. Game developers, network operators, OTT content providers and community operators will have a big role to play in these new paradigms. A broad view will be taken, addressing perspectives of innovation, standardisation, business models, implementation, roadmap, and so on.

Presenting MCN at the EU-Korea Workshop

Invited to the “Korea-EU Workshop: Exploring common research interests in the Future Internet”, 30 September, 1st and 2nd of October 2013

This event follows the 2012 ISTAG report having identified Korea as a relevant third country to jointly perform targeted research in the field of Future Internet. It also benefits from the fact that both Korea and the EU have started focused programmatic initiatives in the Future Internet domain. The purpose of this workshop is consequently: In the short term, to identify Korean and EU projects with similar scopes and objectives to favour “twinning” and information exchanges for the mutual benefits of the running activities; in the medium term, to identify a limited and focused set of research issues of common interests in the two regions which could form the basis of specific joint research in the various upcoming implementations of the Horizon 2020 research programme.

There is an extensive track on “Innovative Internet Architectures”, and this is a perfect place to present “Mobile Cloud Networking“.

Talk: OpenStack Technology and Ecosystem, Datacenter Dynamics Converged 2013

Was invited to talk at Datacenter Dynamics Converged 2013.

DC Dynamics 2013

Very interesting conference, indeed. Latest trends, issues, solutions, hard and software based around Data Centers – all from the perspective of Data Center Operators.

Cloud Computing in this case is the workload and there was frequent mentioning of Data Center Infrastructure Management (DCIM), a topic that we, the ICCLab, address in our new project GEYSER from an integrated Cloud Computing and Energy Efficiency perspective. This is a hot (pun?) topic these days and I am quite keen to see substance around this. Can’t tell much more at this stage, but with GEYSER and a new and excellent chap joining our team for that topic we should have all things together.

Here are the slides of the talk for download.

1st IEEE Workshop on Mobile Cloud Networking (MCN 2013)

The 1st Workshop on Mobile Cloud Networking (MCN 2013) will be held in conjunction with the IEEE International Conference on Communications 2013 (ICC 2013) on June 9-13, 2013, in Budapest, Hungary, see also:


The workshop will bring together researchers, engineers and users, who are interested in future mobile telecommunication networks and/or cloud computing applications and enabling technologies. MCN will discuss recent trends in telecommunication networks and cloud computing and will in particular focus on challenges to be solved when integrating these technologies as well as possible synergies of these technologies.

Access to cloud storage and computing service via wireless/mobile networks should be optimized in terms of delay, bandwidth and energy consumption from an end user perspective. Moreover, there is an increasing trend to implement more and more functions of a mobile telecommunication network in software, e.g., for signal and protocol processing. This enables to use cloud computing infrastructures as processing platform for signal and protocol processing of mobile telecommunication networks, in particular for current and future generation mobile telecommunication networks. In particular, the integration of protocol and application/service processing allows several opportunities to optimize performance of cloud applications and services observed by the mobile user, whose device is connected to the cloud via wireless access networks.

The workshop solicits original contributions in the topics of interest for the workshop. Those topics include but are not limited to the following:
