2. A centre of expertise in digital information managementwww.ukoln.ac.uk 2 About The Session Abstract “What are the potential benefits which Open APIs and Software as a Service (SaaS) seek to provide? What about the associated risks in moving from an environment in which software is installed and managed either locally or by a hosting agency with formal contractual agreements to a environment in which there may be no formal agreements, the services may be hosted in different countries and governed by different legal frameworks? And at a time of global economic uncertainties, is it sensible to be seeking to make use of Open APIs and SaaS? …” Workshop will “explore strategies for exploiting the benefits of and managing the risks associated with these services”.

8. A centre of expertise in digital information managementwww.ukoln.ac.uk 8 What Do We Mean By “The Cloud”? Cloud computing is Internet ("cloud") based development and use of computer technology ("computing"). It is a style of computing in which dynamically scalable and often virtualised resources are provided as a service over the Internet. Users need not have knowledge of, expertise in, or control over the technology infrastructure "in the cloud" that supports them. From Wikipedia http://en.wikipedia.org/wiki/File:Cloud_computing.svg

9. A centre of expertise in digital information managementwww.ukoln.ac.uk 9 What Is Cloud Computing? “.. a broad array of web-based services aimed at allowing users to obtain a wide range of functional capabilities on a ‘pay-as-you-go’ basis that previously required tremendous hardware/software investments and professional skills to acquire.” Via Irving Wladawsky-Berger

11. A centre of expertise in digital information managementwww.ukoln.ac.uk 11 What About SaaS, PaaS, IaaS, etc? “The concept incorporates infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) as well as Web 2.0 and other recent (ca. 2007–2009) technology trends which have the common theme of reliance on the Internet for satisfying the computing needs of the users.” Introduction Wikipedia “Everything as a service (EaaS, XaaS, *aaS) is a concept of being able to call up re-usable, fine-grained software components across a network” Wikipedia “I think there is a world market for maybe five computers” Thomas Watson mis-quote Wikipedia

12. A centre of expertise in digital information managementwww.ukoln.ac.uk 12 Definitions SaaS:Model of software deployment where provider licenses an application to customers for use as a service on demand. SaaS software vendors may host application on their own web servers or download the application to consumer’s device. PaaS:Delivery of a computing platform and solution stack as a service. It facilitates deployment of applications without the cost and complexity of buying and managing the underlying hardware and software layers. IaaS:Delivery of computer infrastructure (typically a platform virtualization environment) as a service … an evolution of Web hosting. Introduction

20. A centre of expertise in digital information managementwww.ukoln.ac.uk 20 What Do We Mean By ‘Risk’? “Risk is a concept that denotes the precise probability of specific eventualities” When should we take risks? Never If the probability is low If the dangers are insignificant If the context if appropriate But what if human life is at risk: In the army Driving a car Travelling on the train … We can’t ignore the context, the potential benefits and the costs Barriers

21. A centre of expertise in digital information managementwww.ukoln.ac.uk 21 Core vs Chore What type of services can you provide via the cloud? Chore services: Services you have to provide even though they aren’t part of your organisation’s key mission (e.g. email, payroll, …). Keep the core services that you care about in-house. Core services: Services key to organisation’s mission. Global organisations (Google, Amazon, etc.) are better placed to provide such services, especially if you have limited technical expertise, resources, … Keep the chore services in-house, allowing you to manage internal IT services. Barriers From David Harrison, (Cardiff Uni.) and developed by Paul Walk What’s the most appropriate context for museum services?

22. A centre of expertise in digital information managementwww.ukoln.ac.uk 22 Sustainability Concerns What happens if SaaS services: Are unreliable? Change their terms and conditions (e.g start charging)? Become bankrupt Things to remember: Services may be unreliable e.g. Twitter Market pressure is leading to changes to T&C – & paid-for services may become free (e.g. Friends Reunited) Banks may go bankrupt too – but we still use them Need for risk assessment and risk management Barriers

23. A centre of expertise in digital information managementwww.ukoln.ac.uk 23 Interoperability Issues What happens if SaaS services host your data and: You can’t get the data back out? You only get the unstructured or poor quality data back out? You can’t get the comments, annotations, tags out? There’s a need to: Ensure data export capabilities or Upload data from an alternative managed sources Understand limitations of data export / import and make plans around limitations Barriers

A centre of expertise in digital information managementwww.ukoln.ac.uk 27 Risk Management JISC infoNet Risk Management infoKit: “In education, as in any other environment, you can’t decide not to take risks: that simply isn’t an option in today’s world. All of us take risks and it’s a question of which risks we take” Examples of people who are likely to be adverse stakeholders: People who fear loss of their jobs People who will require re-training People who may be moved to a different department / team People.. required to commit resources to the project People who fear loss of control over a function or resources People who will have to do their job in a different way People who will have to carry out new or additional functions People who will have to use a new technology Strategies

28. A centre of expertise in digital information managementwww.ukoln.ac.uk 28 IWMW 2006 & Risk Management IWMW 2006 has taken a risk management approach to its evaluation of Web 2.0 technologies: Agreements: e.g. in the case of the Chatbot. Use of well-established services: Google & del.icio.us are well-established and have financial security. Notification: warnings that services could be lost. Engagement: with the user community: users actively engage in the evaluation of the services. Provision of alternative services: multiple OMPL tools. Use in non-mission critical areas: not for bookings! Long term experiences of services: usage stats Availability of alternative sources of data: e.g. standard Web server log files. Data export and aggregation: RSS feeds, aggregated in Suprglu, OPML viewers, etc. Strategies
