Getting your head into 'the Cloud'
- 1. Education Graduate Students' Association (EGSA)/ Association d'étudiant.e.s diplomé.e.s d’éducation (AÉDÉ) Presents: Tech Talks by Rebecca Getting your head into ‘the Cloud’
- 2. About Rebecca • PhD Candidate • Technology adoption and mobile learning • B.Sc. in Computer Science • MA in Distributed Learning (Distance Ed) • Blogger – http://rjh.goingeast.ca – http://goingeast.ca/blog
- 3. Agenda 1. Evolution of the Internet 2. Changing Software Models 3. Synchronous Collaboration 4. File Management Services
- 4. What is ‘the Cloud’? “Cloud computing” Data and services anytime, anywhere
- 5. Evolution of the Internet World Wide Web Tim Berners-Lee Mosaic first browser Internet Explorer “Web Log” Jorn Barger “Web 2.0” Tim O’Reilly Wikipedia Facebook YouTube Twitter Social Media iOS App Store 1989 1993 1995 1997 1999 2000 2004 2005 2006 2008 2011? ‘The Cloud’
- 6. Influencing Factors Increases in connection speed Increases in Internet connected mobile devices 1. Changing Software Models 2. Synchronous Collaboration 3. File Management Services
- 8. ‘The Cloud’ as a shift in Software delivery Software as a product Software over the Internet Software as an App (in an ecosystem) Software as a Service (SaaS)
- 9. Product versus service – an analogy When you buy “Software as a Service” or SaaS, you are ‘renting’ access to the computers that run the software
- 10. Example: Adobe Creative Suite Product: Adobe Creative Suite (CS6) Design and Web Edition Service: Adobe Creative Cloud $449.00 (education price) $29.99 / month (education price) 9 Creative Suite Applications All 24 Creative Suite Applications Version CS6 Latest version of all applications Although Adobe Creative Cloud is sold as SaaS, the applications do not run in the Cloud. You still need to download the applications to your computer.
- 11. Example: Virtual Campus Product: Blackboard Vista (Web CT) Service: Blackboard Learn Hosted on uOttawa servers (uOttawa owns and maintains servers) Hosted at Blackboard (Blackboard owns and maintains servers) Support provided by: 1. uOttawa Blackboard 2. uOttawa IT Support provided by: 1. uOttawa Blackboard 2. Blackboard Governed by Licence agreements Governed by Service Level Agreements (SLA)
- 12. Example: Qualitative Analysis Tools Product: NVIVO Service: Dedoose $670 $12.95/month Windows Windows or Mac Application based Browser based Data on your machine Data in the Cloud Supports collaboration (shared data sets)
- 14. Example
- 15. Activity: Collaborating with Google Docs • Precursor to Google Drive • Allows multiple people to work on a document at the same time • Requires Internet connection
- 16. Activity Debrief • What do you think? • Do you see using it for: – Teaching? – Research? – Collaboration?
- 18. File Management Challenges • Getting files onto devices • Keeping track of most recent version • Keeping old copies • Backing up just in case
- 19. Managing Multiple Versions If you want to access a file when you are not connected to the Internet (offline access), you must make a copy of that file for your local device There is no ‘magic’ solution to managing multiple copies – just services to help you keep track of the latest version and avoid conflicts
- 20. Making changes
- 21. Two versions of the same file
- 22. Data Synchronization Every time your device connects to the Internet - the application checks to see if you have the latest version or if you have made changes If necessary it automatically uploads or downloads the new files
- 23. Data Synchronization may happen: • Automatically when you connect • Only when you connect via Wifi • At specific intervals (for always connected devices) • At specific times • When something changes (e.g. you close a file) A synchronization service also manages conflicts
- 25. Activity: Dropbox • This activity focuses on file sharing, synchronizing, and collaboration • Dropbox also helps with file management across devices (we will cover this in the next session “Going Mobile”)
- 26. Debrief • How did Dropbox differ from Google Docs? • When would you use one versus the other?
- 27. Workshop Evaluation Your feedback is important!
- 28. EGSA Tech Talks by Rebecca Tue Feb 12 Going Mobile Wed Mar 6 Creating your online identity Thu Apr 4 Participants’ choice These events are free; however, donations will be accepted to support the work of the Caring and Sharing Exchange
Notas do Editor
- Term is short for Cloud computing, and has been around since the beginning of computers The Cloud has recently become a trend for talking about services that are available over the Internet The main benefit is “anytime, anywhere” access to data and services Term comes from the Internet being drawn as a Cloud in network diagrams The increase in deployment and capabilities of Internet connected mobile devices is driving the expansion of Cloud services
- 1969 – Birth of the Arpanet – Connection between research universities – and birth of the Internet 1989 – The Concept of the World Wide Web was introduced 1993 – The first web browser, Mosaic (Unix based) – I remember seeing and playing with it in my undergrad 1995 – Internet Explorer – First web browser for the general user (Windows based) 1997 – Term Web Log coined by Jorn Barger (note – it had been happening already) 1999 – Term Web 2.0 coined by Tim O’Reilly Represented a shift in the Internet from content created by web developers to content created by web users 2000 – Wikipedia started 2004 – Facebook launch 2005 – YouTube launch 2006 – Twitter launch Together these represent the social media evolution – the Internet is about connecting people, not just providing content 2008 – iOS App Store opens – not the first App Store, but this really changed the way we buy software 2011? – Somehow “The Internet” became “The Cloud” … trend it towards providing “services” over the Internet rather than just information
- 1 – Share your story about working for Microsoft and on release, you would spend a day on the assembly line packing boxes 2 – Macromedia to download Dreamweaver or Photoshop
- Washing Machine – The thing you actually want is “Clean laundry” .. so you buy the machine to get clean laundry - After purchase, you feed it electricity, water, and soap and it gives you clean laundry - You need an appropriate place to install it - When it gets old or breaks, you need to buy a new one Dry cleaners / Laundry service - You drop off dirty clothes - Pay money - Get clean clothes - You don’t need to care about the equipment or maintenance costs associated with process Someone else owns and maintains the equipment necessary to do the laundry. You in essence, “rent” the equipment in order for you to get clean clothes - A Laundromat is another example of a “service” .. someone else is maintaining and managing the infrastructure.
- - One time cost versus ongoing cost - Service – immediate access to upgrades without additional costs - Companies want to provide you with “services” because it means they don’t need to manage old versions - With a service, you give up control over versioning - e.g. Facebook – interfaces keep changing – it is a service, you don’t get control over versioning
- Another example – Virtual Campus (Blackboard Vista) was a product – uOttawa maintained the servers. We have just moved to Blackboard Learn, which is a service. - Services are governed by SLA – Service Level Agreements
- Notice that Skype puts their logo in a Cloud … Who uses Skype? Is there anyone who hasn’t? When I started my Masters in 2003 – Skype was founded the same year. Our groupwork was done using MSN Messenger (text-only based communication) Note that I also used MSN Messenger for work – as I worked at home about 60% of the time The cohort a year after us used Skype – and when I took a course at Athabasca last semester, Skype was how we did our group work. It has changed distance education (e.g. I now hold Skype office hours when I teach). There are others: Facetime (Apple only), Google hangouts
- Files exist in multiple places. How do you get them between devices (delivery issue) How do you make sure you always have the latest copy (synchronization issue) How do you back them up so that don’t loose them?
