VxRail Appliance - Modernize your infrastructure and accelerate IT transforma...Maichino Sepede
An overview of the VxRail Appliance, including what’s new with VxRail on the 14th generation PowerEdge server, and advancements in the VxRail 4.5 software.
One of the biggest issues for a developer – whether they are an engineer at an OEM or working for a mobile AI application startup – is that their apps are at the mercy of pre-set power and performance settings as defined by OEMs or Silicon vendors. So how can a developer break through that barrier when it seems their hands are tied behind their backs? The Snapdragon Power Optimization SDK allows developers to control the CPU and GPU frequency much more finely from their own application logic. This provides developers with more control within the bounds of the power/thermal framework.

Modernizing Testing as Apps Re-ArchitectDevOps.com
Applications are moving to cloud and containers to boost reliability and speed delivery to production. However, if we use the same old approaches to testing, we'll fail to achieve the benefits of cloud. But what do we really need to change? We know we need to automate tests, but how do we keep our automation assets from becoming obsolete? Automatically provisioning test environments seems close, but some parts of our applications are hard to move to cloud.
Modern Cloud-Native Streaming Platforms: Event Streaming Microservices with A...confluent
Microservices, events, containers, and orchestrators are dominating our vernacular today. As operations teams adapt to support these technologies in production, cloud-native platforms like Pivotal Cloud Foundry and Kubernetes have quickly risen to serve as force multipliers of automation, productivity and value.
Apache Kafka® is providing developers a critically important component as they build and modernize applications to cloud-native architecture.
This talk will explore:
• Why cloud-native platforms and why run Apache Kafka on Kubernetes?
• What kind of workloads are best suited for this combination?
• Tips to determine the path forward for legacy monoliths in your application portfolio
• Demo: Running Apache Kafka as a Streaming Platform on Kubernetes
The Kubernetes cloud native landscape is vast. Delivering a solution requires managing a puzzling array of required tooling, monitoring, disaster recovery, and other solutions that lie outside the realm of the central cluster. The governing body of Kubernetes, the Cloud Native Computing Foundation, has developed guidance for organizations interested in this topic by publishing the Cloud Native Landscape, but while a list of options is helpful it does not give operations and DevOps professionals the knowledge they need to execute.
Learn best practices of setting up and managing the tools needed around Kubernetes. This presentation covers popular open source options (to avoid lock in) and how one can implement and manage these tools on an ongoing basis. Learn from, and do not repeat, the mistakes of previous centralized platforms.
In this session, attendees will learn:
1. Cloud Native Landscape 101 - Prometheus, Sysdig, NGINX, and more. Where do they all fit in Kubernetes solution?
2. Avoiding the OpenStack sprawl of managing a multiverse of required tooling in the Kubernetes world.
3. Leverage technology like Kubernetes, now available on DC/OS, to provide part of the infrastructure framework that helps manage cloud native application patterns.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

17. Natural Virtualization via QorIQ™ P4080 Datapath
►Datapath
decouples cores and peripherals– allows N cores to
share M peripherals
►Accessed
by “Portals” that are per-core
►Allows
direct and efficient access by cores to many high-speed
peripherals
Cores can access the same network
interface with no SW synchronization
because cores have their own portals

19. Market Analysis
“Developers overwhelmingly
voted for the chip's softwaredevelopment tools as the
most important thing when
evaluating a new embedded
processor.”
“The most valuable feature of
a chip isn't even the chip
itself.
Compilers and debuggers
trump MIPS and megahertz.”
- Jim Turley, ESD

20. Migrating to Multicore: What is the pathway?
►Contain
►Exploit
►Analyze
►Optimize
Multicore 101
21. Containment
Goal: Migrate application codebase to multicore
platform without disruption
►Risk
– concurrent execution will expose latent race
conditions and synchronization issues
►Technique
– utilize Linux's processor and interrupt
affinity APIs to contain your application's threads and
processes to a single core
Multicore 101
25. Migration with Containment
The designer can explicitly control which CPUs are permitted to
handle particular threads and interrupts

27. Why SMP?
►Multicore
CPU's can permit a number of processing scenarios
►SMP
maximizes run-time flexibility to match CPU to the needs of
the moment
►SMP ends up playing a role in many system architectures
►Combined with a hypervisor SMP does not exclude any other
design options
Multicore 101
28. Linux’s Long March to Multicore
►Linux
has been MC ready for years
►Kernel, drivers, protocol stacks, and
apps are ready
►As core count scales the focus shifts
to exploiting MC at the application
layer
Multicore 101
30. Sidebar Summary
►SMP
is the natural way for Linux to exploit multicore processors.
►Hypervisors can permit new flexibilities
►New hardware features are making hypervisor based
architectures more efficient to use

32. Exploit
Goal: Identify code that will benefit from multicore execution
and modify code to exploit available cores
Multicore 101
33. Application Architectures to Exploit MC
Objective: scale efficiently across multiple cores so that more client
work can be handled rapidly
►
Key question is how to map client requests (or packets)
to workers quickly and obtain speed-up from multicore
Multicore 101
34. Application Characteristics
►Each
request requires a small
amount of work
►Requests are largely
independent of each other
►Requires read-only access to
a moderate amount of state
►Small amount of state may
travel with the request
►Must be able to manage
overload effectively

For telecom/datacom applications an event driven
architecture is ideal to facilitate multicore migration
Multicore 101
37. Sample Application Architecture
Similar to that used by memcached & Apache
► Dispatcher
can handle overload, monitoring, etc.
► Multicore awareness only for central services
► Plugable Dispatcher is feasible if planned correctly
► Managing global, per service, per session, and per request state is the
battleground for scalability
