Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
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.

Google apps reseller
1. 8 rules to build web app on
top of Google AppEngine
effectively
Lessons learned
www.comvai.com
2. Google App Engine
• Keep in mind Google AppEngine supports
subset of Java EE specifications. Check at
http://code.google.com/p/googleappengine/wiki/W
www.comvai.com
3. 1. Design Data model as simple as
possible
• The App Engine Datastore is not traditional relational SQL database and
there are several important differences.
• AppEngine datastore is schemaless. Entities of the same kind can have
different properties. The application itself is responsible for ensuring that
entities conform to it.
• If you want to migrate your existing data model to App Engine you will
probably need it to redesign.
• Data-model consistency will be split to the data-model and application.
• Check app engine datastore limitations to understand it. It gives you better
overview regarding your future data-model design.
http://code.google.com/appengine/articles/datastore/overview.html
www.comvai.com
4. How to
• Use recommended High Replication Datastore HRD.
• Use Objectify with JPA annotations over built-in JPA or JDO.
• Prefer to use unowned relationships between entities.
• Forget about count entities over filtered query result. Design your UI so
that count is not being required.
• If you need statistic calculations, do it on entity update.
• Note: Building data model on top of built-in either JPA or JDO doesn't
guarantee that application will be vendor independent because of different
behavior of AppEngine datastore in some cases. Even it doesn't mean that's
not possible to do so just requires understanding of AppEngine datastore
behavior.
www.comvai.com
5. 2. Handle your data model via non
default version of your GAE app
• The AppEngine allows you to deploy more than one non default version of
your application. Deploy specifically designed application to perform update
of your data model only as a non default version to be independent from
your main application release cycle.
www.comvai.com
6. 3. Price shields tips
• Use Appstats out of the box tool to detect datastore bottleneck. Just plug
in. It helps you to find the hidden unnecessary datastore operations that are
dragging you down.
• Use memcache. Datastore operations costs money and caching of "static"
data could save you from using unnecessary datastore operations.
• Use as many static files as possible. Static files are handled with high
performance static front-end servers (CDN) which are highly optimized for
this type of content.
• See more

www.comvai.com
7. 4. Improve cold startup time
• AppEngine instances starts quite often thus cold startup time (known as
well as warmup request, loading request) is more important than in
traditional Java EE application. Good startup time improves user experience.
• Minimize number of your application java library dependencies as much as
possible. Make sure if all your libs are really needed. Otherwise it will slow
your cold startup time down.
• Don't use JSP if you are already using another Frontend framework
• Using JSPs will add additional libraries into your lib directory that are used
for processing of JSP.
http://www.listry.com/blog/2010/03/google-app-engine-cold-start-tip-dont
• Use Objectify over built-in JPA or JDO.
http://www.listry.com/blog/2010/03/google-app-engine-cold-start-guide-for
www.comvai.com
8. 5. Prefer Google Guice as DI framework
• It's simple, small in size and powerful library and you probably won't need
more.
www.comvai.com
9. 6. Use GWT for your desktop like web
app
• GWT together with GAE offers lot of built-in technics to improve your
web app performance. Built-in features coming as advice from the book
High Performance Web Sites.
• It's better to have only one framework for the UI even it means to build
some components yourself. Among other things it means less dependencies
and simplified upgrade process.
www.comvai.com
10. How to GWT
• Use built-in optimization technics with help of GWT's ClientBundles.
• ClientBundles and ImageResource makes using images more efficient.
• CssResource for CSS minification, CSS image strips and much more, see
docs for ClientBundles (DataResource, TextResource,
ExternalTextResource).
• Switch on minification and obfuscation of the Java-JavaScript compiler.
www.comvai.com
11. How to GAE
• Content Delivery Network CDN
• Gzip compression
• Memcache
www.comvai.com
12. 7. Use GWT MVP pattern
• It's not easy to work with but worth of time. GWT has built-in support for
MVP pattern.
www.comvai.com
13. Benefits
• Well suited for large scale application.
• Separation of functionality into components. Helps simplify UI unit testing.
• Built-in browser history management. MVP is not concerned with browser
history management, but Activities and Places may be used very well with
MVP development.
• Built-in event bus as a central point for app events.
• Caching all of your code books via GWT event bus as a central pipe to go
to the backend.
www.comvai.com
14. 8. Use Apache Wicket for website
• The component based web framework. Version 1.5 or higher optimized for
Google AppEngine
• In Java ecosystem there is a lot of front-end frameworks thus to choose the
right one depends on many varying factors. We like Apache Wicket because
it's Java, feature rich component-oriented framework with good API. As
version 1.5 it very well operates on App Engine. So it's up to you and your
requirements but ones Apache Wicket is good fit for you we recommend it.
• Add wicketstuff-gae-initializer dependency along side with wicket core
dependencies
• Alternative Play framework as it has specific module for App Engine.

Concept for free.
