Background info: About me
• Darko Grabar Working at University of Zagreb, Faculty of
Organization and Informatics
Head of Software Development Center and E-learning Support Center
Softer developer with strong relation to Open source and e-learning
Involved in e-learning projects since 2005
Participated in development of several e-learning strategies at institutional and country wide level
Part of several Croatian working bodies that deals with Open Source / Open Access and e-learning
Background info: Why this topic
• This is what I do Trying to be one step ahead of teachers by predicting
future usage of ICT in learning
• E-learning is at its turn point New Web 2.0 technologies LMS crisis Bigger gap between rich and poor
• Cloud technologies are ready To be used by masses To provide cheep, reliable and powerful services
E-learning today
E-learning is a process of education (learning and teaching process)
conducted using the Information and Communication Technology which
improves the quality of the process itself and the quality of its result

Future of e-learning
E-learning today
Why the future is not here?
What are the problems?
Software is available
Hardware can support it
Network is ready
There are people that know how to use new technologies
Students/children are demanding it
E-learning today
Resources!
If there would be enough resources:• Schools would hire more teachers• They would have experts in ICT and e-learning• They would have appropriate ICT equipment• Teachers would have time to produce
quality e-learning materials• ICT staff would have time to provide top-of
the line environment for e-learning• Students/pupils would be able to use it • And the list goes on…
E-learning today

• So what’s wrong with e-learning today?
Outdated technology Closed systems Slow innovation Lack of resources
Money ICT resources People
Available only to “privileged”

What is “The Cloud?”
Cloud computing is the use of computing resources (hardware and software) that
are delivered as a service over a network (typically the Internet)
Cloud computing entrusts remote services with a user's data, software
and computation
Wikipedia
What is “The Cloud?”
It is “a mechanism for delivering scalable business services that
execute on a decentralized computing fabric composed of
commodity software and hardware”
What is “The Cloud?”
It is a “pay-per-use model for enabling available, convenient, on-demand
network access to a shared pool of configurable computing resources”
What is “The Cloud?”
Not a new idea
What is “The Cloud?”
Relies on Virtualization
What is “The Cloud?”
What is “The Cloud?”
• Infrastructure as a service (IaaS)• Software as a service (SaaS)• Platform as a service (PaaS)• Storage as a service (STaaS)• Desktop virtualization• Data as a service (DaaS)• Database as a service (DBaaS)• Test environment as a service (TEaaS)• API as a service (APIaaS)• Security as a service (SECaaS)• Backend as a service (BaaS)
What is “The Cloud?”
Analogy
How many of you build your house?
What is “The Cloud?”
Analogy
Are you renting/owning apartment?
What is “The Cloud?”
Advantages
Cost Effective
Unlimited resources
Speed & Scales
Fast innovation
Backup and Recovery
Automatic software integration
Easy Access
What is “The Cloud?”
Disadvantages
Change in thinking
Security in the Cloud
Technical Issues
Inflexibility
Cost
What is “The Cloud?”
Is it only for large Corporations?
E-learning and the cloud
How to make e-learning accessible and affordable
E-learning and the cloud
Case: teaching ICTGoal:
To provide advanced education in the field of ICT (programming and multimedia) to students in schools in the form of blended e-learning course.
We want to teach two courses Big Data Processing 3D Modeling
Requirements:• Learning Management System for delivering courses• E-Portofilo system for student collaboration • High computing power needed for large files
manipulation and 3D modeling• Large data storage• High speed network
E-learning and the cloud
Case: teaching ICT
Let’s do it “traditional way”
We will need:• Server• Install LMS, e-portfolio, databases, ...• High speed network connection• Computer classroom
Screen projector 20 computers (workstation class): fast processor, 8GB of RAM (min),
500GB disk, fast graphic card Windows and Linux OS Install all required software on each computer Fast local LAN connected to high speed broadband connection
• What about when working from home?

Case: teaching ICT
Let’s do it “Cloud way”We will need:• Cloud environment with configured applications• Computer classroom
Screen projector 20 low end computers: enough processing power to run OS and
browser Any OS capable of running standard browser or Cloud native client Network connection (2-3 > Mbps)
• What about when working from home? You can, from any computer (even smart phone or tablet)

Discussion
• Are you using e-learning technologies? What technologies (LMS, e-Portfolio, other?...) Typical examples
• Would you use cloud services if available? In what context If no, why not?
• What functionality would you like to see in the “E-learning in the cloud environment”?
