Hideo Kimura from DeNA presented on the MBGA Open Platform and the Hermit gadget server. The key points are:
- The MBGA Open Platform uses OpenSocial 0.9 and allows third party developers to build gadgets and integrate them into social networks.
- Hermit is the gadget server implemented in Perl using PSGI and Plack. It uses pluggable modules and can handle high volumes of requests through lighttpd and FCGI.
- Future directions include supporting OpenSocial 1.0, developing template APIs, and integrating additional authentication methods.
Expect the unexpected: Anticipate and prepare for failures in microservices b...Bhakti Mehta
This session covers best practices for building resilient, stable RESTful services that can survive failures in distributed environments, such as transient impulses, random load, stress, or failures from some dependent components. It focuses on various techniques such as circuit breakers, bulkheads, and fail fast to ensure that services stay up and keep running despite failures.
Java EE 8 Presentation given at NYC Java SIG on May 4, 2017. This presentation provides the latest information on the forthcoming release of Java EE 8 in June.
Jakarta EE is now over 20 years old and despite its age, it is as relevant today as it was back in 1999. It is one of the few open standards for developing enterprise applications with multiple independent vendor implementations. Its APIs are central to developing Java based cloud solutions. It is as relevant today as it was back in 1999. This presentation will provide context to Jakarta EE and why businesses choose to use it.

HTTP, JSON, JavaScript, Map&Reduce built-in to MySQLUlf Wendel
HTTP, JSON, JavaScript, Map&Reduce built in to MySQL - make it happen, today. See how a MySQL Server plugin be developed to built all this into MySQL. A new direct wire between MySQL and client-side JavaScript is created. MySQL speaks HTTP, replies JSON and offers server-side JavaScript. Server-side JavaScript gets access to MySQL data and does Map&Reduce of JSON documents stored in MySQL. Fast? 2-4x faster than proxing client-side JavaScript request through PHP/Apache. Reasonable results...

Vaadin - thinking of U and I - by Peter Lehto
Vaadin (vaadin.com) je Java framework za rapidni razvoj visoko interaktivnih HTML5 web aplikacija na poslužitelju. On sakriva tehnologije prijenosa dokumenata i stanja (DOM, AJAX, JSON) i omogućuje da web aplikacije budu razvijene u Javi prema metafori desktop aplikacija. Vaadin iskorištava svu moć GWT-a, Java-to-JavaScript prevoditelja, pa je moguće razviti cijeli stog web aplikacija i nove komponente na strani klijenta bez napuštanja Java okruženja. Brzi razvoj olakšava veliki izbor komponenata i trenutni deployment na poslužitelj. Vaadin aplikacije koje se izvode na poslužitelju pružaju veliko povećanje sigurnosti, kao i povezivanje Vaadin sučelja na bilo koji postojeći backend sustav. U predavanju bit će prikazan pregled Vaadin 7.1 mogučnosti, pogled na Vaadin arhitekturu i što se zapravo događa iza kulisa frameworka, a bit će raspravljene i značajke koje donosi Vaadin 7.2.

Using Riak for Events storage and analysis at Booking.comDamien Krotkine
At Booking.com, we have a constant flow of events coming from various applications and internal subsystems. This critical data needs to be stored for real-time, medium and long term analysis. Events are schema-less, making it difficult to use standard analysis tools.This presentation will explain how we built a storage and analysis solution based on Riak. The talk will cover: data aggregation and serialization, Riak configuration, solutions for lowering the network usage, and finally, how Riak's advanced features are used to perform real-time data crunching on the cluster nodes.
Achieving Infrastructure Portability with ChefMatt Ray
Deploying to the cloud has made it easy to run large numbers of servers, but users may become dissatisfied with their particular cloud platform for reasons such as price, support and performance. There are a number of vendor lock-ins to avoid, this talk discusses how to do so with the open source configuration management and infrastructure automation platform Chef. Chef makes it easy to deploy to nearly every public and private cloud platform as well as virtualized and physical servers. Chef may also be used to deploy cloud infrastructures such as OpenStack, Eucalyptus or CloudStack. By abstracting away the platform, infrastructure becomes portable and you are free to deploy wherever necessary.
OVHcloud Tech Talks S01E09 - OVHcloud Data Processing : Le nouveau service po...OVHcloud
Nous vivons une époque où tout est connecté, de nos ampoules à notre éditeur de texte, les objets et services qui nous entourent devienne de plus en plus intelligents. Pour ce faire ils génèrent des données, elles sont nécessaires au bon fonctionnement du service ou de l'objet, mais elles sont également utiles pour faire évoluer les produits.
Ces données peuvent rapidement représenter de gros volumes, plusieurs dizaines voir centaines de gigaoctets. Une question se pose alors, comment traiter de tels volumes ? Comment en tirer du sens et de la valeur à cette échelle ?
Avec OVHcloud Data Processing, une solution basée sur le framework Apache Spark, nous répondons à ce besoin. Venez découvrir comment vous aussi, en quelques cliques, pouvez exécuter votre code sur une infrastructure taillée pour vos besoins.
Au travers de différents exemples, comme une analyse du traffic des taxis New-Yorkais, nous verrons comment Data Processing a été pensé, comment il fonctionne et comment il peut être utilisé pour valoriser vos données.
Chef for OpenStack - OpenStack Fall 2012 SummitMatt Ray
Chef for OpenStack is a collaborative project for the deployment and management of OpenStack clouds. This is an overview of the status of the project at the OpenStack Fall 2012 Summit
Chef is an open source configuration management and service integration automation tool that has been integral to a number of large successful OpenStack deployments. This talk will provide a brief introduction to Chef and why it frequently the configuration tool of choice for large deployments and discuss the use of Chef within the OpenStack ecosystem (development, testing, deploying and managing the installation). Chef also provides the ability to manage the instances running on top of Nova through the knife-openstack plugin.
Apache Spark v3 is a new milestone for the Big Data framework. In this session, you will (re)discover what Spark is, learn about the new features in its third major version, and go through a complete end-to-end project.
I like to call Spark an Analytics Operating Systems. It is offering far more than just a framework or a library. I will explain why. Spark v3 is the latest major evolution. It was released mid-June 2020 and adds impressive new features. After looking at them from a high level, I will detail a few of my favorites.
Finally, as we all like code (well, at least I do), I will demonstrate a complete data & AI pipeline looking at Covid-19 data.
Key takeaways: Spark as an Analytics OS, Spark v3 highlights, building data/AI pipelines/models with Spark.
Audience: software engineers, data engineers, architects, data scientists.
