Welcome letter

Requirements of IT services are growing. Costs drive to seeking more efficient solutions taking into account the availability requirements. Is your datacenter full, old and energy consuming? Is building new space the only option or could infra as a service be a better solution?

A wide range of cloud services is available. What kind of technology is behind these solutions? What is required to build own cloud? Is it worthwhile to build your own cloud or is joint procurement a better choice? What if the services are outsourced, how to ensure high quality of services? How can energy efficiency be ensured when capacity is obtained as a service? This workshop tries to find answers to the above questions.

The participants are challenged to ask questions from the speakers and discuss with each other to find out the critical areas of datacenter IaaS procurement. If such areas exist.

The workshop is open to anyone and will be held on 11-12.9.2014 in Helsinki, Finland.


The intended target audience is the network engineers working with deployment of IT services on campuses and NREN staff involved in datacenter and campus deployments.

The program of the workshop consists of the following themes:

  • Green datacenter technologies
  • Cloud service provisioning
  • Joint procurement, costs and agreements
  • Security and standards
  • Network

Welcome to the workshop!


On behalf of the program committee,

Janne Oksanen

Modular DC solutions: CSC Kajaani datacenter

Somewhere in 2009 CSC started to investigate new location for the datacenter which could host next supercomputers. And after 3 years we had one of the most eco efficient DC in the world hosting computing services for the Finnish academia, research institutes and EU projects. Past couple of years we have had production ongoing have shown our selections and design principles were right ones. Very reliable and extremely low PUE in a same DC package, that is CSC Kajaani datacenter.

Do-it-yourself traditional DC

If creating a Datacenter from scratch is not an easy task, re-organizing an existing computer room into a decent DC can be quite of a headache. This talk will do a survey of several techniques and existing products from vendors that will allow you to transform your old-fashioned computer room into a (almost  :-) ) brand new datacenter. The talk will cover :

- airflow control : how can you create hot and cold aisles at low cost ?
- cooling technologies : are you ready for free-cooling ?
- How can you monitor best ?
- can you improve your PUE ?

For each of these items, we will give cost estimates and achievement difficulty level.

Strategic approach to cloud computing deployment

The presentation will demonstrate a survey of cloud services adoption in European NRENs, obtained through the questionnaire circulated among 23 NRENs. Based on these results, the presentation will cover a strategic approach to deployment of cloud computing and services which is driven by a business cases for the users community. A set of information and different aspects need to be analyzed to setup strategic objectives which are desirable, feasible and achievable, and therefor which are worth investing in.

Providing IaaS to Greek Academic Users

GRNET currently runs more than 11.000 VMs in two flavors of IaaS services. In this presentation we're going to show how we build and provision these IaaS/cloud services. Our solutions have to cater to different needs, from students to labs and from university NOCs to scientists that need computing resources. We're going to present the open source tools, both 3rd-party and in-house developed, that we use everyday in order to deploy, automate and monitor our services.

Provisioning Cloud Services to Academic Users in the Czech Republic

## Introduction

CESNET, an association of legal entities established by universities and the Academy of Sciences of the Czech Republic, is responsible for operation and development of the National Research and Education Network (NREN), National Grid Infrastructure (NGI) and active research in the field of advanced network technologies and applications.

As a provider of scientific computing services for the Czech academic community and a facilitator of international connections to European Grid Infrastructure (EGI), CESNET has considerable experience with virtualization-based solutions such as virtualization as a tool for operation flexibility, on-demand virtual cluster services for scientific computing or HPC cloud.

The national Center CERIT-SC (CERIT Scientific Cloud) offers storage and computing resources and related services, including support for their experimental use. The Center also participates in research and development related to flexible e-Infrastructures and it also collaborates in research activities of its partners.

The CERIT-SC Center was created through a transformation of the Supercomputing Center Brno (SCB), a part of the Institute of Computer Science (ICS) at Masaryk University (MU).



## Scientific cloud for academic community

As a part of a joint effort, CESNET and CERIT-SC provide an IaaS cloud service for academic use. This venture was motivated by the need to react to requirements from user communities with an increased flexibility. In most cases, it allows for provisioning of highly specialised worker nodes for scientific computing applications, and acts as a new interface to existing NGI resources. Therefore an evaluation in terms of cost is not the primary goal, cost cutting is not the reason for deploying a cloud in this environment. The primary focus is the support of new and more diverse user communities.

The scientific cloud infrastructure provides users with two essential services. The Infrastructure as a Service (IaaS) cloud for launching virtual machines and The Storage as a Service (STaaS) cloud for file-based storage and file sharing.


### IaaS

The IaaS cloud infrastructure at CESNET/CERIT-SC is based on OpenNebula an open source cloud

 management framework, which has been extended and integrated with various pre-existing NGI services such as:

* Accounting (MetaAcct)

* Monitoring (PBSMon, Nagios monitoring probes for OpenNebula)

* User management (The Perun management system)

* Authentication and authorization (Kerberos and X.509)


In general, it is used to run on-demand nodes with user-supplied images as well as worker nodes for the national grid environment.

As a leader of the virtual machine management activity in the context of the EGI Federated Cloud, we are focusing on standardization and interoperability while providing several components used in various places of the federated cloud ecosystem. Most notably, the rOCCI framework implementing the Open Cloud Computing Interface (OCCI) in Ruby and providing both client-side and server-side ready-to-use products.


### STaaS

CESNET has its own storage service providing storage and archiving capacity for grid and cloud users alike via standardized protocols such as FTP or NFS. One of several ways to use this large storage capacity is the OwnCloud-based STaaS generally available for end users.


## Outcome

The aforementioned services create a solid foundation for a scientific HPC cloud which has proven to be an efficient tool for supporting new and existing user communities with a considerable increase in flexibility. Similar trends are also emerging in the European e-Infrastructure as demonstrated by the EGI Federated Cloud effort and its recent move to production. As a result of the participation in multiple international cloud-oriented projects and internal efforts, we can share our technical expertise on a plethora of subjects including but not limited to interoperability, infrastructure design and management, user management and AAI.

Cost of outsourced datacenter services


Experiences of broad scale outsourcing of datacenter services in a Finnish UAS

Decision to outsource is always a strategic initiative and needs to be made by the highest management. Before making the decision to outsource there are few questions that needs to be considered and answered: What is the core business of the organization, does the present service support the core business in a strategic level or is it more a supportive service, do we have enough skills and employees to effectively produce service by ourselves, would it make economically sense to outsource, etc.

Conditions for a successful outsourcing are manifold. Main thing is to know what you are outsourcing before you do as well as what is the total cost of ownership - including training and life cycle costs. To find out total costs of an in-house service can be tricky but the better you succeed in this “spy” task the better informed decision you are able to make. In addition to salary and social security costs there are bunch of other “hidden” costs that needs to take into account. Without them in-house production may feel too cheap and you miss the realistic comparison.

There are also other things than money that needs to take into account. You need to figure out what are indirect effects of outsourcing for the organization. What changes are needed if there will be another party to deliver part of the process? How information will flow from one party to the other and back? Will there be lack of confidence between different parties? Will there be temporary or even permanent drop in service level for your customers etc.

In Laurea UAS we did not go through outsourcing in traditionally sense BUT rather a partial in-sourcing! When Laurea was founded in the late -90’s whole IT-function was outsourced. During the years uncertainty towards an outsourced IT function started to raise and made the management to think whether outsourced IT was too inflexible and expensive. Requirements of teaching had changed and multinational service provider was not able to bend to these requirements. During the spring 2004 decision was made to perform a partial in-housing which led to a so called hybrid-model where there is a place for in-house and outsourced services. How we have organized our IT is quite different from most of the higher education institutes in Finland.

Come and hear how IT is organized in Laurea University of Applied Sciences, what led to this model, what are the benefits of our current model of operation, what could have been done differently and how we have organized cooperation with our vendors.

How to calculate cost effiency of energy


May I propose a little bit different approach of the subject? Because the purpose of our work is DataCenter (DC) – IaaS – Green IT. So, my presentation will not give you a formula to calculate the cost efficiency of energy in a DC, but in a more global approach, I propose to look at where are the problems, what kind of “solutions” we can expect; and what we can do.


Energy is clearly the challenge of the 21th century. Two centuries of “industrial revolution”, something like 1850 to 2050 will have use a very large amount of fossil combustibles, 100 000 000 years of production ! We have no choice we must develop renewable sources of energy at a very large scale.

DCs :

DCs are the “back office” of the internet. Users (most of) see the internet through their smartphone or tablet. Just a very few users know that a single “clic” cost a large amount of energy, very bigger than their personal (terminal) usage. The talk will provide some significant numbers; example : global (world wide) electricity consumption of network enabled devices in 2013 = 616 TWh; global electricity consumption in France in 2013 = 547 TWh !!!


Green … nothing is green or virtual in the ICT world. Just a few countries such as Iceland can provide renewable energy at human scale, but what about building servers and so on and recycling ?

OK, what can we do ?

Ideas to act in the better possible way.

Safe file storage and databases

Increasingly, data is stored in seemingly private containments in public locations. This poses challenges due to the differences between perceived and actual safety of the data. Safety here refers to security, privacy, reliability and availability. The talk will present two software prototypes for file storage and simple relational databases which can be used in multi-user environments to offer non-expert users a safe environment for their data across multiple locations.

SURFdrive: an Owncloud sync & share service



Simple and secure data sharing

Although many commercial personal storage services are free, no one

knows exactly where the data is stored, or what it is subsequently used

for. There is a secure alternative for users in the Dutch higher

education and research community. SURFdrive offers staff, researchers

and students an easy way to share and synchronise files within a secure

community cloud with ample storage capacity.


Privacy and security

In order to offer users a secure and reliable service, all SURFdrive

information security protocols meet high standards. The Legal Framework

for Cloud Services in Higher Education serves as a guideline for all

service-related agreements. SURFdrive complies with all Dutch and

European privacy legislation. For example, SURFdrive's conditions of use

ensure safe usage, whereby users retain ownership of their own data. All

data is securely stored within the Netherlands. Furthermore, SURF does

not share information with third parties.


This presentation is about the legal policy's and technical choices in

order to offer a secure sync & share service that is based on Owncloud.

elfCLOUD - Credibly secure cloud storage

elfCLOUD is a Finland based secure cloud platform. The platform combines the privacy of private clouds with cost-efficiency and ease of maintenance of the public clouds.

The entire architecture has been designed from the ground up with primary focus on information security and end-user privacy. Content is always
encrypted locally on the users' device before transmitting to the cloud. The content keys are never sent to or stored on the elfCLOUD servers in usable format. Secure cloud assisted key sharing within and across organizations is supported and facilitated in a user-friendly manner.

The elfCLOUD platform provides open APIs and open-source client libraries as well as a set of readily available client applications for day-to-day file management, sharing, folder synchronization and backups.

AMRES Virtualization Solution


Virtualization offers higher infrastructure utilization, faster service provisioning and significantly reduces the data center footprint. A couple of years ago, Academic Network of Republic of Serbia (AMRES) acknowledged these benefits and started a project which aims to virtualize server infrastructure in AMRES datacenter. Due to lack of funds AMRES was forced to turn to some low-cost solutions (open source virtualization platforms) such as Citrix XenServer and Proxmox. In this session we will present the AMRES virtualization environment and share some of the experience we gathered during these years.

Practical information

  • Moving around Helsinki: There's an extensive public transport system in the greater Helsinki area. Taxis and Airport Taxi services are also available. It takes about 45 minutes to reach Helsinki center from the Airport using public transport. Taxi service halves the time. The rush hours (7:00-9:00, 15:00-17:00) usually double the driving time. Taxi from Airport to Helsinki center costs around 40-50e.
