The Largest Portion is Network Traffic
Network Traffic Cost
Cut down Cost by Optimizing Contents Delivery Procedure

2. Problems & Solutions
Optimizing Cost
•Grasp the characteristic of UCC Service
"Let users have their contents as fast as Possible!“
Not always Good.
Not all users are play video files till the end
If we could restrict download bandwidth to minimum...?

2. Problems & Solutions
Optimizing Cost
•What we did
What we need was a little more than 1Mbps per session.
Set max download bandwidth
Infinite 5 Mbps
Try to use just as much as we need.

2. Problems & Solutions
Optimizing Cost
•The Result
Immediate Response: Network Traffic Reduced 15%
We also can cut the cost about 10% a month
Before After Decrement Ratio
Day 1 24 Gbps 19 Gbps - 15.4 %

Convincing an organization that performance matters and is worth investing in is often a tough thing to sell. This was no different at Intuit, who operated many sites built in the pre “web standards” era. Then, one day, one test changed everything – an A/B comparison successfully demonstrated that faster page loads increased conversion and SEO. And the conversation quickly changed from “Not interested” to “How quickly can you make the rest of our pages faster?” A performance team was formed, and optimization began across multiple properties in a phased approach with each release delivering incremental performance gains. As we iterated through the core performance principles, the team introduced additional techniques that led us to exceed our original performance goals. Techniques such as lazyloading, prefetching, smarter image optimization/spriting, and module rewrites enabled us to successfully shave off additional time. This session will cover the steps that we took, lessons learned including what worked well or didn’t work well, as well as the performance improvements that were realized, and their impact on business metrics. Some of the topics include: * How we went from 15s web pages to 2s web pages * How combining CSS/JS files and image sprites had both positive as well as negative impact * How lazy loading of resources and JavaScript rewrites improved our page render times (including our experiments with Control.js) * How we addressed blocking as well as high-latency third-party components * How we solved for issues/constraints arising from shared code across multiple sites * How we optimized for user flows spanning multiple pages with positive results * How automated benchmarking enabled us to continuously monitor our performance health * How we succeeded in making “performance” a common theme among developers, marketers, and stakeholders

Presented at EDUCAUSE CCCG March 2021. The IceCube Neutrino Observatory is the world’s premier facility to detect neutrinos. Built at the south pole in natural ice, it requires extensive and expensive calibration to properly track the neutrinos. Most of the required compute power comes from on-prem resources through the Open Science Grid, but IceCube can easily harness the Cloud compute at any scale, too, as demonstrated by a series of Cloud bursts. This talk provides both details of the performed Cloud bursts, as well as some insight in the science itself.

The microservices honeymoon is over. When starting a new project or revamping a legacy monolith, teams started looking for alternatives to microservices. The Modular Monolith, or 'Modulith', is an architecture that reaps the benefits of (vertical) functional decoupling without the high costs associated with separate deployments. This talk will delve into the advantages and challenges of this progressive architecture, beginning with exploring the concept of a 'module', its internal structure, public API, and inter-module communication patterns. Supported by spring-modulith, the talk provides practical guidance on addressing the main challenges of a Modultith Architecture: finding and guarding module boundaries, data decoupling, and integration module-testing. You should not miss this talk if you are a software architect or tech lead seeking practical, scalable solutions. About the author With two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.

When you’re building (micro)services, you have lots of framework options. Spring Boot is no doubt a popular choice. But there’s more! Take Quarkus, a framework that’s considered the rising star for Kubernetes-native Java. It always depends on what's best for your situation, but how to choose the best solution if you're comparing 2 frameworks? Both Spring Boot and Quarkus have their positives and negatives. Let us compare the two by live coding a couple of common use cases in Spring Boot and Quarkus. After this talk, you’ll be ready to get started with Quarkus yourself, and know when to select Quarkus or Spring Boot.

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.
