Ottimizzare le performance dell'API Server K8s come utilizzare cache e eventi...Luigi Fugaro
Il serve API di Kubernetes è un componente fondamentale per la gestione dei cluster e l'interazione con le risorse del cluster. Tuttavia, le richieste ripetitive e le risposte voluminose possono causare problemi di prestazioni. In questo talk esploreremo come utilizzare i meccanismi di caching per migliorare le prestazioni del server API di Kubernetes e come utilizzare gli eventi per invalidare la cache in modo efficiente. Verranno presentati esempi concreti di implementazione e verranno discusse le best practice per l'utilizzo di questi meccanismi nell'ambiente di produzione. Imparare a utilizzare questi strumenti può aiutare a ridurre i tempi di risposta e aumentare la scalabilità del cluster.

App Cloud Native?
E i dati dove li mettiamo?
Azure offre tantissimi servizi per ospitare la applicazioni più disparate, dai monoliti (su VMs), ai micro servizi (grazie al servizio Kubernetes fully-managed - aka AKS) alle Azure Functions.
Tutto molto bello, ma migrare un'applicazione (dal lift-and-shift al refactoring) non è cosa banale. Tal volta si ha la necessità di tenere parte degli asset nei data center aziendali (il cosiddetto on-premise) e un'altra parte (magari più veloce da migrare) sul cloud.
E quindi i dati dove li scriviamo?
Sul cloud o sull'on-premise?
Ad ogni modo, la latenza sarà un problema.
Le performance saranno un problema!
E quindi?
La risposta è dentro Azure, con il suo servizio Azure Cache for Redis Enterprise, che permette di fare il deployment del nostro dataset geo-distribuito, con dati sempre aggiornati e consistenti, in cloud e on-premise.
Red Hat Summit Connect 2023 - Redis Enterprise, the engine of Generative AILuigi Fugaro
Redis è conosciuto come un database in tempo reale che può essere utilizzato come cache, per memorizzare sessioni utente o immagazzinare token d’autenticazione, documenti JSON, per gestire inventari in tempo reale, dati geografici, come feature store in scenari di machine learning, gestione di code, broker, stream e molto altro. Ma non tutti sanno che Redis può memorizzare e indicizzare vettori di embeddings, ovvero quelle strutture dati che sono alla base di applicativi come ChatGPT. In questo talk, esploreremo come utilizzare Redis come un database vettoriale per implementare casi d’uso moderni.
Unleashing the Power of Vector Search in .NET - DotNETConf2024.pdfLuigi Fugaro
Redis OM .NET has evolved to embrace the transformative world of vector database technology, now supporting Redis vector search and seamless integration with OpenAI, Azure OpenAI, Hugging Face, and ML.NET. This talk highlights the latest advancements in Redis OM .NET, focusing on how it simplifies the complex process of vector indexing, data modeling, and querying for AI-powered applications. Vector databases are redefining data handling, enabling semantic searches across text, images, and audio encoded as vectors. Redis OM .NET simplifies this innovative approach, making it accessible even for those new to vector data. We will explore the new capabilities of Redis OM .NET, including intuitive vector search interfaces and semantic caching, which reduce the overhead of large language model (LLM) calls.

Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

12. Stateless vs Stateful
• Stateless è considerato da sempre il miglior modo
per scalare
• Le tecnologie che creano un mapping artificale fra
client e server sono stateful per natura
• Stateful: JSF, Wicket
• no scalability, dimensionamento difficile
• Stateless: Javascript diretto, generatori di Javascript
(GWT)

14. Neolitico
• Nel Neolitico è decisamente possibile fare rich
client solo con il browser
• Javascript (con JQuery) è la tecnologia abilitante
• JSon il formato dati, Ajax il protocollo, REST
l’architettura
• HTML 5 a seguire, è completamente in linea con
questa architettura

15. Come si realizza un 2.5 tier
• JQuery
• Libreria Javascript per consumare servizi REST e creare
componenti riusabili
• si, funziona anche su IE6 :)
• Esposizione dei dati come servizi tramite librerie
REST
• JAX-RS è lo standard
• RestEasy è la migliore implementazione, ma ce ne sono
altre

17. REST Architecture in una slide
• Dissertazione PHD di Roy Fielding (coautore di
HTTP), 2000
• REpresentational State Transfer
• Ovvero, usare il Web così com’è per far
collaborare le applicazioni: HTTP è molto più
ricco di quanto si creda!
• Soprattutto in antitesi a WS-* (SOAP, WSDL,
UDDI, ecc.), anche se Roy Fielding presentò un
concetto più ampio

18. REST Architecture in una slide
• HTTP a pieno potenziale
• PUT, POST, GET, DELETE (l’equivalente di un CRUD)
• ma anche OPTIONS, CONNECT, TRACE, HEAD
• URI come identificativo di una risorsa (Addressability)
• Uniform interface (ogni risorsa deve essere acceduta
allo stesso modo)

• Una applicazione che sia buon cittadino del Web
deve rispettare il protocollo HTTP e la semantica
dei suoi “verbi”
METHOD URI

24. Safety & Idempotenza, perchè?
• Google accelerator
• client side caching tool, rilasciato nel 2005
• prefetching dei link delle pagine visitate con un
browser
• assumeva che le GET fossero safe
• NON funzionava con moltissimi siti!

25. REST in Java
• JAX-RS (JSR 311): The Java API for RESTful Web
services
• E’ uno standard, Jersey è la reference implementation
• Facilissimo produrre XML o JSON
• RESTEasy è una delle implementazioni migliori
• Ne parleremo diffusamente nel prossimo talk! Non
cambiate aula :)

"postalCode": “00100”
• RFC 4627 },
• Formato semplice per "phoneNumbers": [
"346 1234567",
scambiare oggetti: "330 8901234"
alternativa light ad XML ]

28. JQuery
• JQuery
• JQuery è divenuta negli ultimi anni la libreria dominante
nel panorama javascript
• John Resig, l’autore di Jquery, è stato il pioniere
dell’unobtrusive Javascript
• oggi anche altre librerie vanno nella stessa direzione
• è utilizzatissima per la semplicità con cui si ottengono ottimi
effetti grafici cross browser
• permette di separare struttura e comportamento

29. Unobtrusive Javascript
• Unobtrusive Javascript
• I CSS permettono di separare la presentazione dalla
struttura
• Una libreria js unobtrusive separa anche il
comportamento dalla struttura
• Si “attacca” il comportamento alla struttura tramite dei selector
(CSS compatibili)
• Il comportamento è cross browser, ci pensa la libreria ad
applicare workaround

• JTemplates è una libreria di Templating client side
• Sfrutta JQuery
• Semplice e leggera (circa 12Kb)
• Permette di scrivere “cascading templates”
• Risolve il problema della componentizzazione delle
interfacce HTML/JS

34. JQuery e 2.5 tier
• L’idea di base dell’architettura 2.5 tier è quella di
utilizzare Javascript e JQuery per fare... tutto.
• Tenendo “ferma” l’architettura REST, dunque solo servizi
• Nessun codice lato server che non sia RESTEasy
• ok le validazioni le abbiamo lasciate lato server :)
• Tutto il resto è sul client
• Solo pagine “statiche”
• Componenti JQuery + templating Javascript (JTemplate)
• What else?

35. Reverse Ajax
• L’architettura 2.5 tier è Comet-compliant
• se si vuole un full MVC, con notifiche dirette verso le
View, si può utilizzare una delle tecnologie Comet
• Comet consiste nel tenere aperta una connessione verso il
server per ricevere gli eventi
• Termine coniato nel 2006 da Alex Russell (Server push, HTTP
push, HTTP Streaming, Pushlets, Reverse Ajax)
• diversi modi di realizzarlo, e diversi contro: attenzione ai
Firewall, alla Scalabilità, alla Server Affinity.

37. Scalabilità
• 2.5 tier scala all’infinito
• Le URI sono inerentemente scalabili. Il Web è
inerentemente scalabile. Dietro ad una URI può esserci
un semplice Tomcat, ma anche un bilanciatore hardware.
E dietro SOAP?
• Se la GUI è solo sul client, i server possono essere
stateless. E anche se le pagine diventano decisamente più
pesanti, possono sfruttare la cache del browser
• Attenzione a Comet, però.

38. Caching / Pipelining
• Con 2.5 tier possiamo cachare fino all’inverosimile
• cache delle query verso il DB
• cache di HTTP
• Cache-Control in HTTP 1.1
• ci permette di NON trasferire verso il browser i risultati che
sappiamo non essere cambiati
• cache del browser di tutta la GUI (html e js)
• pipelining (effettuare il fetch di più risultati del necessario
e conservarli nel client)

39. Security
• Con 2.5 tier la sicurezza è semplificata
• Due possibili approcci
• usare un IDM (IDentity Manager)
• essendo tutta l’applicazione basata su URI, il matrimonio con
un IDM non presenta grossi problemi
• necessario plugin per l’AS se si vuole colloquiare con l’IDM per
migliorare la fruibilità e l’estetica dell’interfaccia
• utilizzare la sicurezza standard JEE, annotando
semplicemente i metodi esposti tramite REST

40. Server side agnostic!
• Una GUI interamente JS e che consuma JSON è
indipendente dalla tecnologia server side!
• Si possono scrivere componenti (datatable, calendari,
ecc.) e riciclarli all’interno di un’azienda complessa con
architetture miste e non monotecnologiche
• Java, .Net, Scala, Erlang, PHP, C, C++, etc.
• Si può dire che 2.5 tier faciliti il riuso all’interno di una
Enterprise più di ogni altra soluzione ad oggi conosciuta

42. Conclusioni
• Oggi è possibile utilizzare un’architettura full REST
in un’azienda enterprise
• Oggi è possibile utilizzare un MVC completamente client
side, senza ricorrere ad “aiutini”
• Le applicazioni saranno:
• indipendenti dal client e dal server, riusabili (SOA), belle
graficamente (ok, solo se avete un grafico bravo),
performanti, e scalabili ai limiti estremi.
• perciò non è solo possibile, ma anche consigliabile...
