The Total Cost of Ownership (TCO) of Web Applications in the AWS Cloud - Jine...Amazon Web Services
Weighing the financial considerations of owning and operating a data center facility versus employing a cloud infrastructure requires detailed and careful analysis. In practice, it is not as simple as just measuring potential hardware expense alongside utility pricing for compute and storage resources. The Total Cost of Ownership (TCO) is often the financial metric used to estimate and compare direct and indirect costs of a product or a service. Given the large differences between the two models, it is challenging to perform accurate apples-to-apples cost comparisons between on-premises data centers and cloud infrastructure that is offered as a service. In this presentation, we explain the economic benefits of deploying a web application in the Amazon Web Services (AWS) cloud over deploying an equivalent web application hosted in an on-premises data center and highlight the 5 things to not forget while calculating TCO.

To Cloud or Not to Cloud - If you're in a transaction production environment, should you move to the Cloud? What does the Cloud mean for transaction document operations? For transaction archives? For customer support and end user access to transaction documents?
What do you need to know about The Cloud to make the decisions whether To Cloud or Not To Cloud?
This presentation is useful for who wants to know about the basics of cloud computing and the various approaches of cloudcomputing.It also explains the various advantages/disadvantages and also the risks of cloudcomputing.
The cloud presents organizations with a new way to deliver IT services. It can significantly lower costs, improve efficiency, and, if implemented well, provide significant competitive advantage. But cloud computing takes a number of forms: private, public hybrid and combinations of these. These options can be confusing in terms of their technical implementations as well as their economics.
This session describes the various types of clouds and major trends in the cloud market. It also looks at the economic issues to consider when making the decision on whether to go with cloud, and if you choose cloud, which path to take.

Context: The missing ingredient in multilingual software translationNetcetera
Take a look at how automated end-to-end tests can be involved to support and speed up the software translation process. Mirjana’s quest at Selenium Conf 2018 in Chicago is to show you with examples how to feel the content and, in the same time, also feel the context of that content.
An important phase in multilingual software systems is text translation. Since same text may be used in different contexts, it is difficult to determine whether the translation is proper in the context of the environment in which the text is used. Sharing only text keys and values with translators usually is not enough. Simple screenshots showing only the text content, also didn't help in situations where text keys were re-used on multiple places, or when there are highly generic templates. This presentation contains an efficient automated way of delivering the necessary artifacts to translation experts. These artefacts contain text keys, text values and also the context where they are used.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Editor's Notes
*) Pay-as-you-go can take various forms, important aspect is: you pay for what you consume But it can even be upfront (e.g. pre-paid phone)
The 10 laws of cloudonomics (Joe Weinmann, 7. September 2008) Costs less even though it costs more: think pre-paid phone vs. monthly base fee + reduced cost for calls
IaaS This is probably the most well-known cloud service model reported by the media. However, cloud compute-on-demand is also an easier to understand next step after in-house virtualization and co-location. When the resource need is known in advance but generally very irregular over time, IaaS is a viable approach to cost savings. However in many application the resources needed over time are not known especially if it depends on external demand (such as a web site that gets very popular because of a specific event). However, after initial “low-hanging fruit” of just moving a virtualized service into the “Cloud” next steps get tougher: Scaling a service needs manual effort or additional tools and measures There is likely a need to re-design (maybe even from scratch) to successfully move to an inherently more distributed platform. Only on PaaS (migrating to which may also need heavy application architecture change) do you get (in some cases at least) automatic reduction of scaling details PaaS Platforms simplify architecture of applications by providing a more abstract model of its service, providing simpler deployment and hiding the complexity of scalability behind their interface to the application developer. In the best case (i.e. when there is a good fit to the service’s model) a user does not have to worry about scalability or availability simply by adhering to the platforms APIs. Lock-in The biggest drawback to consider however is “lock-in”: For IaaS, there are already many abstraction (cross-platform) APIs around that help mitigate the risk of locking the user to a specific provider. For platforms, this will be more difficult, although there are also already first open source implementations of existing platforms (e.g. AppScale, which is an open source implementation of the Google AppEngine) SaaS A SaaS provider is basically a ASP, as it was called a couple of years ago. While the Cloud lets providers leverage existing infrastructure and the traditional ASP based his offering mostly on his own infrastructure, the difference for the actual user is insignificant. With SaaS too, the main characterization is: self-service, pay-as-you-go and on-demand. Moving from local installations to SaaS allows new capabilities that are not possible locally: e.g. simultaneous editing of documents. Variety Whenever a software can potentially be accessed with a browser, it is a candidate for SaaS. This implies that the number of offerings and services will explode even more in the near future. The difficult question when exploring possibilities is that the market is changing even faster than the IaaS and PaaS market. --- BTW: Deployment Models: Private cloud. The cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on premise or off premise. Community cloud. The cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on premise or off premise. Public cloud. The cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services. Hybrid cloud . The cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds). -> Actually, there is no (technical) reason for anything else but public cloud…
January 2011: Racksace is still 10 servers behind Amazon
At these quantities, special purchasing arrangements are the norm (Google pays only a fraction of the market price for their servers, $500 for 16GB 2 CPU server, 2009) Unlimited backup for ~50$ per year?! Cool for customer, but how can it work for Backblaze? Not necessary to be able to read the actual figures: the size of the bars are enough…
Assumption of 50% utilization is quite high!
Typical risks The slides collects some critical risks that one might become more exposed to through the use of Cloud Computing. Being aware of what can go wrong and how bad it can be, is very important especially for first movers. It only takes one catastrophic early experience to cause potentially over-compensating measures which could limit the ability to profit from Cloud benefits for a long period of time before trust is again rebuilt or the technology becomes so mainstream that it overcomes the negative bias. Devising measures to mitigate the risks After having identified such risks, it is in everyone’s interest to define reasonable measures to prevent such cases from occurring. Easy to take measures include encryption of data or the introduction of checklists. Such measures are what many people think of as governance. Perhaps the easiest way to get buy-in is to elicit recommendations on such measures from the first movers. Such users are likely to recognize the danger of negative events and are more likely to actively participate in governance measures that they have helped to devise.
