Quarkus stories: Logging Made Simple With Quarkus, MDC, and Google Cloud

We'll take a look at how pairing MDC with JSON logging in Quarkus lets us enrich the logs with all sorts of goodies, and allows us to better understand what's going on in our application once it’s deployed to Google Cloud.

Quarkus stories: Kako razširiti podporo razvojnim storitvam

Razvojna storitev (dev service / dev resource) je “embedded” oz “containerized” način poganjana te storitve znotraj neke aplikacije. Quarkus jih podpira že kar nekaj, npr. različne podatkovne baze, Kafka, Apicurio Registry, Keycloak, Infinispan, ElasticSearch, itd

Razvojne storitve so primerne oz. priročne za “dev” in “test” razvojno okolje (profile), kjer po večini potrebujemo prazne oz. s predvidljivimi podatki napolnjene storitve.

Kaj pa, če želimo dodati novo razvojno storitev?

Kaj, če jih želimo dodati več oz. veliko?

V tem kratkem predavanju bomo predstavili svoj način poganjanja in ustavljanja lastnih razvojnih storitev. Spoznali bomo osnove Quarkus “lifecycle”-a in “extension”-ov, ki sta pomemben del te lastne implementacije razširljivih razvojnih storitev.

Quarkus stories: Our take on messaging with Quarkus extension, RabbitMQ and AsyncAPI

In a process of moving to event-driven architecture, we build an infrastructure that makes interservice and client-service communication as simple as possible - especially for developers using it. We'll take a look at how we took advantage of a custom Quarkus extension and a pair of maven plugins to reach that and have developers use it with just a few annotations.

Revolutionizing Java-Based Cloud Deployments with GraalVM

Ultra-fast Java In-Memory Database Apps & Microservices with Java

Software solutions of the future will use AI, machine learning, IoT, big data, etc. and have to process data tons of data in realtime. Applications will more and more base on microservices and serverless infrastructures where each service or function has its own database. Traditional databases cannot keep pace in terms of performance and are too heavyweight and expensive in the cloud.

MLOps: best practices of putting machine learning models to production

Everyday we are being bombarded by new machine learning achievements revealed by world's leading labs in industry and academia. However, for most companies, the sad reality remains that most machine learning models never actually reach production. And for those that do, the problems in maintaining them through their lifecycle often outweigh their business benefits. This calls for a new approach how to address the complex dynamic between code, data and models that machine learning introduces. I my talk I will present the key principles of MLOps, an approach to productivization that aims to bridge the divides between data scientists, data engineers and DevOps specialists.

Ali je Oracle Autonomous Database prihodnost razvoja Oracle baze podatkov?

Oracle Autonomous Database je več-modelna Oracle baza podatkov, ki v osnovi temelji na relacijskem modelu (tabelah) in je hkrati še JSON baza podatkov s podporo za MongoDB API in JSON kolekcije, XML in prostorske podatke (Spatial)
in hkrati podpira graf podatkovni model in metode strojnega učenja nad vsemi prej naštetimi podatki. Podatki so shranjeni v klasični transakcijski obliki ali kolumnar komprimirano obliki, po potrebi lahko Autonomous baza dostopa do zunanjih podatkov na S3 kompatibilnih objektih (Object Storage) s Avro, ORC ali Parquet formatom podatkov.

What Does Serverless Really Mean, and What It Can Do for You?

Everyone is talking about serverless these days - they say: “Your apps should be Serverless”. But what is serverless exactly? Only Web sites? Is it a silver bullet for every use case? Let’s see what serverless means, how you can use it to implement different ideas and projects, and what benefits it brings to the table.

From DBA to Data Scientist. Are you ready for a career change?

As the companies move into more complex systems of data management, the role of data scientist becomes extremely improtant.

Business users and Oracle Machine Learning in Oracle Analytics

Traditionally, the use of machine learning is in the domain of the data scientist. The latter has in-depth knowledge of machine learning methods and algorithms and strives for the most optimal preparation of machine learning models, which are then used for various analyses such as predictions, customer segmentation, anomaly detection, finding patterns and the like.

Hey DBMS_COMPARISON! - Are my Tables in sync?

Nowadays, companies have a lot of databases to store their data. Besides the application-specific data, master data is required (e.g. customer or employee information) to run the application. If the data is replicated between many databases, it is essential that the data and its tables are fully synchronized - especially when a non-Oracle replication technique is used (e.g. a third-party application).

CloudVane's journey into multicloud cost

Dean will share CloudVane’s incredible journey – from its inception as a necessity to manage cost in a multicloud environment to its full fledged maturity as multicloud cost bus for the largest and most innovative technology project in Saudi Arabia and, let’s be honest, probably the world.

Uporaba spletnih komponent v Javi

Že od nekdaj pri razvoju programske opreme težimo k uporabi ponovno uporabnih komponent, ki imajo skrito svojo notranjost in so dostopne le preko vmesnikov. Pri razvoju spletnih aplikacij v Javi se komponente pojavljajo na različnih nivojih. Precej dobro je uveljavljena uporaba komponent na strežniški strani, nekoliko manj pa so uveljavljeni pristopi z uporabo spletnih komponent na odjemalski strani.

Fundamental Oracle Security – What Many Of You Are Not Doing [REMOTE]

I tend to work in a few companies each year. Something I have been getting asked more and more, other than “make it faster”, it how to secure the Oracle database – frequently because of a failed audit. In companies and governments, I see; poor auditing, no security consideration, no lockdown of accounts, inadequate processes, and lots of risk.

Geografsko razpršeno privatno oblačno okolje namenjeno kritičnim aplikacijam

Ogromno podatkov, povezljivost ter oddaljene lokacije predstavljajo velike izzive. Iskratel z rešitvijo Iskratel Cloud Platform naredi več zasebnih oblakov na oddaljenih lokacijah, ki uporabniku približajo računsko moč, avtomatizirajo delovanje ter skrajšajo čas obdelave.

Evolving your APIs, a step-by-step approach

When you publish your first HTTP API, you’re more focused on short-term issues than planning for the future. However, chances are you’ll be successful, and you’ll “hit the wall”. How do you evolve your API without breaking the contract with your existing users?

In this talk, I’ll first show you some tips and tricks to achieve that: moving your endpoints, deprecating them, monitoring who’s using them, and letting users know about the new endpoints. The talk is demo-based, and I’ll use the Apache APISIX project for it.

When capacity is limited

We got confronted with old hardware and notably very slow storage. The job we had to do involved, unavoidably, a large amount of Writing and reading. We’ll present and discuss some of the measures we tried / failed / succeeded to survive until we got our new+shiny hardware…

It was a bit like pointing firehoses at a sink, and then try not to let it overflow.

The key to capacity-management, in this case, was to carefully monitor our system, and to push it to the limit, but NOT Beyond.

Oracle Integration Cloud: integracija ter razvoj mobilnih aplikacij za nadgradnjo sistemov v oblaku.

Kako SaaS aplikacije in svoje podatkovne baze, ne glede na to, ali so v oblaku ali na on-premises sistemih, povezati z varno in enotno integracijsko storitvijo?

V številnih podjetjih integracije niso ravno priljubljena tema, saj v procesu integracije najrazličnejših podatkovnih baz in aplikacij pogosto pride do odstopanj, zamud in nepotrebnih stroškov. V izogib naštetemu vam predstavljamo Oracle Integration tehnologijo, ki s pomočjo predpripravljenih adapterjev, avtomatizacije procesov in vizualizacije vaših podatkov z mobilno aplikacijo predstavlja edino tehnologijo, ki jo boste potrebovali, da boste lahko povezali svoje poslovne procese. Odgovore na to, kako nagraditi svoje on-premises sisteme z oblačnimi storitvami ter kako izboljšati uporabnost SaaS aplikacij, ki jih vsakodnevno uporabljate, bomo iskali na predavanju Oracle Integration Cloud: integracija in razvoj mobilnih aplikacij za nadgradnjo sistemov v oblaku.

The Future of Java is Bright

In this talk by HUJAK, we present the current state of the tech ecosystem based on Java and related technologies as well as its bright future. This includes the foundation of the platform and virtual machine, features of Java and other programming languages based on it, an enormous number of frameworks, libraries, tools, and services, and most important – the community and people behind it all.

Enostavna gradnja podatkovnih tokov za usmerjanje, analizo ter učenje v “BigData” svetu

Na predavanju bomo predstavili arhitekturo sistema, ki nam omogoča, da v poplavi podatkov na enostaven način zgradimo kontekstno odvisne (namenske) podatkovne tokove. Le tako lahko postane velika količina podatkov obvladljiva in jih lahko dodatno oplemenitimo s pomočjo metod in algoritmov strojnega učenja.

OLVM: Inkrementalni backupi (dirty bitmaps)

Na predavanju bo opisano, na kakšen način lahko v OLVM (oz. qemu, ki teče pod njim) naredimo inkrementalne backupe z uporabo “dirty bitmaps”. Torej na način, da backup po indeksu prebere iz produkcije le spremenjene bloke (ki so se spremenili od zadnjega backupa). Gre za podoben princip, kot ga uporablja Oracle Database EE, če vklopimo BCT (block change tracking).

End-to-end open-source observability system deployment [REMOTE]

Modern cloud-native applications are incredibly complex systems. They are built in various languages, and frameworks and often use different threading models and RPC technology. Understanding the system we are building is a foundation for building a reliable system and meeting SLAs. In this talk, we will talk about rolling out an open-source observability stack in an organization. We will focus primarily on distributed tracing, however, metrics and logs will be covered as well. You will learn about OpenTelemetry, Jaeger, and Prometheus projects.

Looming through Virtual Threads and Modern Memory Management

Java's old Threads, created more than a quarter of a century ago, up till today successfully drove millions of Java applications. Additionally, Java's automatic memory management was efficiently performed for decades using garbage collectors such as Serial, Parallel, CMS, and Garbage First (G1). However, we believe that it is time to take a turn into modern and more efficient structured concurrency constructs, similar to Kotlin's coroutines, and introduce some contemporary scalable low-latency and region-based low-pause parallel and concurrent garbage collectors.

Moderna podatkovna arhitektura za podporo celovitem upravljanju s podatki

Neizogibno dejstvo je, da je količina proizvedenih podatkov skoraj neskončna. Vsaka naprava, vsak klik, vsaka digitalna akcija proizvaja podatke. Večinoma smo se že navadili, da podatke tako ali drugače shranjujemo. Naslednji izziv – ki pa se je pravzaprav že začel dogajati – je izvajanje monetizacije podatke. Zgolj shranjeni podatki so za nas namreč le strošek. S podatkovno ekonomijo pa pretvorimo surove podatke v poslovno vrednost za podjetje. To pa ne velja le za podjetja, temveč širše za celotno pametno družbo, ki temelji na vseh možnih podatkih iz najrazličnejših virov.

Daylight Saving Time (DST) demystified

In Germany, the discussion of the cancellation of the daylight saving time is in full swing. But what does such a change mean for the database and the already stored timestamps? How does the database know when to change from summer to wintertime?

Oracle Cloud za DRC. Kaj pa imam še brezplačno?

Oracle cloud je idealno okolje za več različnih situacij. Velikokrat želimo izvesti kakšno analizo, ki zahteva veliko resursov mi pa jih nimamo, oziroma bi nas stalo veliko preveč, če bi te reurse imeli stalno na voljo.
