This document discusses a Dell Technologies cloud trends panel featuring executives from Dell EMC, Virtustream, VMware, and Pivotal Software. The panel provided an overview of their cloud solutions and was followed by a question and answer session with the audience. Attendees were also encouraged to visit the cloud solutions showcase and attend related breakout sessions at the Dell EMC World conference to learn more about Dell's cloud products and services.

The document compares the total cost of ownership of physical, virtual, and cloud-hosted desktops. It finds that virtual desktops can reduce costs by up to 36% over physical desktops, while cloud desktops deliver further savings of over 20% compared to on-premises virtual desktop infrastructure. On-premises VDI has high upfront infrastructure costs that offset labor savings, while cloud desktops have no infrastructure investment and provide the lowest total cost of ownership through a pay-as-you-go model.

This slide deck addresses the importance of proper functional design for creating resilient distributed systems (not only, but also microservice-based systems). It starts by explaining the pitfall that many developers fall into when getting started with resilience: Quite often the effects of the fundamentals, i.e., creating bulkheads and choosing the communication paradigm, on system robustness at runtime are heavily underrated. Instead, the pure technical measures like circuit breakers, backpressure, etc. are often overestimated. Unfortunately, all technical measures will not help to create a robust system if the functional design leads to highly coupled services where the availability of one service functionally totally depends on the availability of another service. The same is true if you need to call many services that all need to be available to answer a client request. To make it worse, most of the wide-spread design approaches like functional decomposition, DRY (don't repeat yourself), design for re-use or layered architecture exactly lead to those problems, i.e., they are not suitable for designing distributed systems. This slide deck does not offer any silver bullets to solve the problem (and actually I believe there is no silver bullet), but at least a few guiding principles. Additionally, it shows how the choice of the communication paradigm influences the bulkhead design and this way creates more options to create a good service design that also supports resiliency on a functional level. As always this slide deck is without the voice track, i.e., most of the information is missing. But I hope that the slides on their own also provide some helpful hints. Remark: As the "dismiss reusability" slide tends to get quite some attention, one more remark about that slide: On the voice track I usually add "If you find something that is worth being made reusable, i.e., that it satisfies the commercial constraints of Fred Brooks 'Rule of 9' (see https://blog.codecentric.de/en/2015/10/the-broken-promise-of-re-use/ for details), do not put it in a service. Instead create a library and put the functionality in there. And make sure that changes to the library do not mean that all users have to upgrade at the same time, but that any library user can update whenever it fits the user's schedule. Otherwise, you would have introduced tight coupling through the back door again."

Cloud adoption has reached an inflection point, pushing organizations into an "adapt or die" state, forcing new operating models, effective management of internal and external resources, and transformation towards an application-centric mentality. Cloud approaches are maturing past the point of public clouds domination, shifting focus to private & hybrid cloud and effective management of a multi-cloud environment. Attend this session to learn how to realize true business value when the friction of the business dynamic is supported by flexible cloud services delivered with predictability & speed.

This slide deck tries to give an overview about the consistency options we have today and what we can expect in the future. It's an updated version of slide deck I had uploaded to SlideShare before. Unfortunately, SlideShare removed the option to update a slide deck. Thus, I had to remove the old slide deck and create a new one, even if it actually was just an update. It starts with examining RDBMS and ACID transactions - especially looking at the fact that "ACID" does not necessarily mean serializablity (what most developers think of if they reason about consistency). Then it describes the current state of IT affairs concerning Cloud, microservices, NoSQL databases and BASE transactions. It then dives a bit deeper into the topic of polyglot persistence and its challenges by introducing a little "storage dimension model" that may support you in picking the right storage solution that fits your needs. Especially it is pointed out that in the storage world there is no one-size-fits-all solution available and especially that NoSQL databases - definitely having their sweet spots where they shine - are no drop-in replacement for a RDBMS. Afterwards, BASE transactions are examined in more detail - especially the fact that their trade-off for providing us with better availability and scalability is a very hard programming model. To underline that point the typical types of inconsistencies that you often will see with BASE transactions are sketched on what you need to do on the application level in order to cope with them. In the third section, a peek into the future is made by looking at some current research results that will eventually find their way into commercial application development. The core observation is that even in highly available systems there are a lot of options regarding consistency. Yet, most of those options require to reason about consistency explicitly on the application level and no longer solely on the read/write level of the underlying data stores - including building explicit consistency support into the application. In the last section, some recommendation for our daily work are given that can be derived from the former sections. As always the voice track is missing, but hopefully it will give you a few helpful pointers, though. Especially, at the end a lot of references to computer science papers are included that this slide deck is based on.

In this presentation I focus on the architectural aspect of the next generation of enterprise IT topic I already covered in some other presentations. The slide deck starts with a quick motivation. It describes the external drivers that require traditional enterprise IT to change. Based on these drivers, the drivers and requirements for an architecture that supports the external drivers are derived. The second major part of the slide deck then examines some of today's IT hype topics and evaluates them with respect to the architectural requirements derived before. Be aware that the evaluation partially is hard to understand without the voice track. Actually, at some places the explanations on the voice track are more important than the evaluations themselves. Thus, please do not take them too literally. The last major part then tries to sketch a possible architectural style that suits the given requirements. Again, the rationale for picking the respective elements are on the voice track, and it is just one possible style. There are for sure more styles available that suit the needs. Yet I think, the style described makes clear that the upcoming enterprise architectural styles are quite different from the styles that were predominant in the last 10 or 15 years and makes clear that we all have to face new challenges - not only on the architectural level. Sorry again that the voice track is missing. Yet I think, that the presentation provides some helpful ideas even without the voice.

Virtual desktop infrastructure (VDI) represents the future of enterprise desktop computing and brings with it the detachment of OSs and applications from physical endpoints—a compelling trend that promises greater flexibility, scalability, cost savings and security benefits. The movement also represents radical, and possibly painful, changes in market dynamics for providers of endpoint hardware, software and services. Yankee Group analysts Phil Hochmuth and Zeus Kerravala dissect the future of VDI and discuss what the technology has to offer enterprises today.

Join us in this session as we will discuss how Dell uniquely enables customers to protect data, drive efficiencies in systems management, and deliver a reliable end user device all while saving IT time and money to focus on more strategic projects that can help companies grow.

Everything in IT is accelerating exponentially. Moore’s Law continues to hold true, as technology capabilities advance 10X every 5 years. Fast forward 15 years from today and you can expect to see it advance another 1000X. The implication will create a dramatically different era of IT. The Internet-of-Everything is quickly leading us down the path to IT-enabled businesses and economies. There’s another profound shift happening: IT will move from supporting the business, to becoming the business. For IT this presents a dual challenge: accelerate digital transformation to support the requirements of new cloud-native applications, while supporting the traditional applications that run today’s business. IT must be an expert and thought leader in both distinct architectural and operational paradigms. To see the 3 tenets of the clearest path forward to transform IT, see David Goulden’s article: http://reflectionsblog.emc.com/dell-emc-world-2016-a-look-back/ See the session recording at http://dellemcworld.com/live/library/dell-emc-world-keynote-david-goulden-1

This is basically a "lessons learned" talk. While dealing with resilient software design for several years meanwhile, I realized along the way that implementing a specific pattern like timeout detection, circuit breaker, back-pressure, etc. is the smallest of the challenges. As so often in software development, the actual pitfalls that keep you from being successful with your project - here, creating a robust application - are not to be found in the area of creating code. Based on my experiences, the actual pitfalls are to be found in areas that are at best loosely related to resilient software design. In this talk, I discuss some of those pitfalls that I have experienced more than once along my way. It starts with not understanding the goals of resilient software design, continues from a lack of understanding the characteristics of distributed system, over missing required feedback loops and deficiencies in functional design, to not understanding the trade-offs of applying resilience patterns, and ends with the problem of our continuous collective insight loss. The main objective of the talk is to sensitize for the pitfalls. Wherever possible I also added some suggestions how to deal with the topics. Unfortunately, some topics neither have an obvious nor a simple solutions - at least none that I would know about ... As always the voice track is missing and thus a huge part of the content of the talk. Yet, I hope the slides in themselves are of some use for you and offer some helpful ideas and pointers.

The document discusses record labels and their responsibilities regarding artist development, copyright protection, and distribution of music recordings. It explains that major record labels are large, well-funded companies that can heavily promote artists, while independent labels have smaller budgets and promotion capabilities. The document also discusses how record labels are responsible for obtaining copyright permissions for artists' music and content. It notes that permission must be obtained before using copyrighted music in order to avoid legal issues like fines. The document emphasizes learning about record labels and copyright is important for properly planning a music video production using licensed content.

This document analyzes the micro elements used in the opening sequence of the film "Dead Silence" through examining individual camera shots. It discusses how elements like props, lighting, shot types (e.g. high angle, close up), editing, pace, costumes and more are used strategically to set tone and provide meaning and clues about the characters and story to the audience without revealing full details. The analysis of these micro features will help the author construct their own effective film opening by understanding how to manipulate elements like camera work, lighting and more to engage audiences and achieve desired emotional responses.

The document discusses how the filmmaker attracted and addressed their audience through various techniques in the film opening. Common horror film conventions like dark colors, a full moon, an off-kilter camera shot, not showing the antagonist's face, and graphic violence were used to intrigue the audience and build tension. Unusual shots like the 360 degree shot of the woods and the extreme long shot of the antagonist watching a dog walker from afar also attracted the audience by creating an unsettling atmosphere and making the audience feel like prey. These techniques drew the audience in to continue watching and addressed their expectations of the horror genre.

Record labels help develop and promote new artists, and protect artists' copyrights. There are two main types: major labels have more funding and resources, while independent labels have less funding but more creative freedom. The document discusses how an independent label called Glassnote Records would be a good fit for the artist Chvrches, as they release synthpop/indie rock music like bands previously signed to Glassnote. It also covers copyright and how the creator needs permission to use other artists' music, even for non-commercial uses. The creator plans to apply this knowledge by creating their own hypothetical record label called Be Unique Records, which would sign bands across many genres including synthpop.
