Toster - Understanding the Rails Web Model and Scalability Options

Rails стал отличным ответом на требования многих лет опыта использования классической процессной модели веб-запросов. Такая модель все еще является наиболее надежной и простой для понимания и контроля. Но новое поколение высокодинамичных и интерактивных веб приложений требует принципиально новых требований к масштабированию. Одним из ответов на такие требования может стать сервис Pusher.com, который, в числе прочих вариантов решений, будет рассмотрен в этом докладе

Speaking from experience building a SaaS: users are insane. If you are lucky, they use your service, but in reality, they probably abuse. Crazy usage patterns resulting in more requests than expected, request bursts when users come back to the office after the weekend, and more! These all pose a potential threat to the health of our web application and may impact other users or the service as a whole. Ideally, we can apply some filtering at the front door: limit the number of requests over a given timespan, limiting bandwidth, ... In this talk, we’ll explore the simple yet complex realm of rate limiting. We’ll go over how to decide on which resources to limit, what the limits should be and where to enforce these limits – in our app, on the server, using a reverse proxy like Nginx or even an external service like CloudFlare or Azure API management. The takeaway? Know when and where to enforce rate limits so you can have both a happy application as well as happy customers.

For the different Big Data architectures (batch processing, real time processing, Lambda, Kappa ..), we suggest, in a first phase, different Disaster Recovery Plan solutions depending on SLA (Service-level agreement) : RPO (Recovery Point Objective), RTO (Recovery Time Objective).. In a second phase, we focus more on steam processing and existing Kafka solutions for Disaster Recovery Plan (Mirror Maker, Kafka Connect Replicator, GeoCluster ..) : the advantages, the drawbacks and the impact of this choice on the global architecture. Finally, we explain in details how to configure and deploy each Disaster Recovery Plan solution (rack awareness, replication, replication factor, min insync …) and how to integrate each layer (storage layer, processing layer ..) into the chosen architecture.

This talk will present an architecture developed to investigate the interaction with and between animals. The architecture allows online processing of multimedia streams and the generation, storing and visualizing of events using feature extraction. It allows biologists to analyze the events by monitoring live or by replaying streams through a web interface Docker swarm is the central component of the architecture and serves as infrastructure for stream processing, event generation, event processing and visualization. The main entry point for users is a web interface that spins up one container per user and allows independent replay of streams. This talk will focus on the architecture and on technical details concerning its implementation as well as how docker is utilized to process, store and visualize events. Some time will be spent explaining details about custom made docker solutions.

MySQL Webinar, presented on the 25th of April, 2024. Summary: MySQL solutions enable the deployment of diverse Database Architectures tailored to specific needs, including High Availability, Disaster Recovery, and Read Scale-Out. With MySQL Shell's AdminAPI, administrators can seamlessly set up, manage, and monitor these solutions, ensuring efficiency and ease of use in their administration. MySQL Router, on the other hand, provides transparent routing from the application traffic to the backend servers in the architectures, requiring minimal configuration. Completely built in-house and supported by Oracle, these solutions have been adopted by enterprises of all sizes for their business-critical applications. In this presentation, we'll delve into various database architecture solutions to help you choose the right one based on your business requirements. Focusing on technical details and the latest features to maximize the potential of these solutions.

Enterprise Knowledge’s Urmi Majumder, Principal Data Architecture Consultant, and Fernando Aguilar Islas, Senior Data Science Consultant, presented "Driving Behavioral Change for Information Management through Data-Driven Green Strategy" on March 27, 2024 at Enterprise Data World (EDW) in Orlando, Florida. In this presentation, Urmi and Fernando discussed a case study describing how the information management division in a large supply chain organization drove user behavior change through awareness of the carbon footprint of their duplicated and near-duplicated content, identified via advanced data analytics. Check out their presentation to gain valuable perspectives on utilizing data-driven strategies to influence positive behavioral shifts and support sustainability initiatives within your organization. In this session, participants gained answers to the following questions: - What is a Green Information Management (IM) Strategy, and why should you have one? - How can Artificial Intelligence (AI) and Machine Learning (ML) support your Green IM Strategy through content deduplication? - How can an organization use insights into their data to influence employee behavior for IM? - How can you reap additional benefits from content reduction that go beyond Green IM?
