The presentation concludes with monitoring dashboards, anomaly detection, and alerting functionality to simplify operations and identify issues.

Using machine learning to determine drivers of bounce and conversion (part 2)

Tammy Everts

[2016 Velocity NY] There has been a lot of historical work that looks at the relationship between performance and conversions, but most of it has been after the fact or relied on linear models. Google partnered with SOASTA to train a machine-learning model on a large sample of real-world performance, conversion, and bounce data. Patrick Meenan and Tammy Everts offer an overview of the resulting model, able to predict the impact of performance work and other site metrics on conversion and bounce rates. The code used to generate the model is freely available.

Synthetic and RUM - Best of bo

Cliff Crocker

RUM and synthetic monitoring each provide valuable but different performance data. RUM captures real user behavior but numbers vary greatly depending on user environments, while synthetic provides consistent baseline data but doesn't reflect real users. Both data sets are needed to understand a site's true performance across different user scenarios. There is no single performance number, and the right metrics depend on the intended audience and business goals.

Comet: by pushing server data, we push the web forward

NOLOH LLC.

According to the specification of HTTP, which is at the heart of all things web, a client must first request or “pull” information from the server and the server can only issue responses. It is never the other way around, with the server initiating the communication and “pushing” the data as it becomes available. Overcoming this limitation, actually an old and historical problem, would have remarkable applications, benefiting almost every page on the web to various degrees, and significantly enhancing the user experience. And the best part is: you can do it all right now, on any average server environment, and have it work on any standard browser! The modern, Web 2.0 -inspired collection of these solutions, design principles, and techniques for this “sever push technology” is sometimes referred to as “Comet.” I will discuss in detail: the numerous uses and benefits of Comet; the problems and difficulties that developers have to face; the variously accepted solution strategies that exist today including polling, long polling, streaming; their subcategories and their specific implementations, subcategories, advantages, disadvantages, and compatibility nuances; how HTML5 offers to address the issue; as well as outline some original research on the topic. Finally, I will illustrate these concepts and ideas through the live coding of a simple, Comet-based application using the help of a PHP framework with rich Comet support.

How to push data to a browser

alpha86

This document discusses different techniques for pushing data from a server to a browser in real-time, including Comet, a umbrella term for techniques like long polling and server-sent events. It outlines several Comet implementations like Tornado and Twisted, and compares symmetric and asymmetric pub/sub architectures for user-centric and data-centric use cases. Key aspects of building a Comet system are asynchronous I/O, message dispatching, and scaling to handle large numbers of simultaneous connections.

Integrating content delivery networks into your application infrastructure can offer many benefits, including major performance improvements for your applications. So understanding how CDNs perform — especially for your specific use cases — is vital. However, testing for measurement is complicated and nuanced, and results in metric overload and confusion. It's becoming increasingly important to understand measurement techniques, what they're telling you, and how to apply them to your actual content. In this session, we'll examine the challenges around measuring CDN performance and focus on the different methods for measurement. We'll discuss what to measure, important metrics to focus on, and different ways that numbers may mislead you. More specifically, we'll cover: Different techniques for measuring CDN performance Differentiating between network footprint and object delivery performance Choosing the right content to test Core metrics to focus on and how each impacts real traffic Understanding cache hit ratio, why it can be misleading, and how to measure for it

Can the e-Mobility Charging Infrastructure be a Blueprint for other IoT Proje...

Achim Friedland

This document discusses using blockchain technology to improve the electric vehicle charging infrastructure and use of open data. It suggests that blockchains could be used to define data quality standards and service level agreements for charging providers. Smart contracts would enforce these rules and refund data providers based on how useful their data is. For example, routing services could publish possible electric vehicle routes on the blockchain using encrypted open data, and competitors could verify the data was correctly used to route vehicles. This could help incentivize high quality open data and services in electric mobility.

NoSQLmatters

Kai Wähner – Real World Use Cases for Realtime In-Memory Computing NoSQL is not just about different storage alternatives such as document store, key value store, graphs or column-based databases. The hardware is also getting much more important. Besides common disks and SSDs, enterprises begin to use in-memory storages more and more because a distributed in-memory data grid provides very fast data access and update. While its performance will vary depending on multiple factors, it is not uncommon to be 100 times faster than corresponding database implementations. For this reason and others described in this session, in-memory computing is a great solution for lifting the burden of big data, reducing reliance on costly transactional systems, and building highly scalable, fault-tolerant applications.The session begins with a short introduction to in-memory computing. Afterwards, different frameworks and product alternatives are discussed for implementing in-memory solutions. Finally, the main part of this session shows several different real world uses cases where in-memory computing delivers business value by supercharging the infrastructure.

HijackLoader Evolution: Interactive Process Hollowing

Donato Onofri

CrowdStrike researchers have identified a HijackLoader (aka IDAT Loader) sample that employs sophisticated evasion techniques to enhance the complexity of the threat. HijackLoader, an increasingly popular tool among adversaries for deploying additional payloads and tooling, continues to evolve as its developers experiment and enhance its capabilities. In their analysis of a recent HijackLoader sample, CrowdStrike researchers discovered new techniques designed to increase the defense evasion capabilities of the loader. The malware developer used a standard process hollowing technique coupled with an additional trigger that was activated by the parent process writing to a pipe. This new approach, called "Interactive Process Hollowing", has the potential to make defense evasion stealthier.

PLNOG 13: Grzegorz Janoszka: Peering vs Tranzyt – Czy peering jest naprawdę szybszy

1. Is peering really faster? Let the data speak for itself Grzegorz Janoszka AS43996

2. Booking.com in numbers • Booking.com B.V., part of the Priceline Group (Nasdaq: PCLN) • Each day more than 700,000 room nights reserved (#1 hotel booking website in the world) • Over 538000 properTes in 207 countries • Website in 42 languages • 8000+ employees • 135 offices in over 50 countries • 33 million+ hotel reviews

3. Booking.com peering • Live: AMS-‐IX, LINX, Equinix Ashburn, HKIX • Currently being delivered: DE-‐CIX • Work in progress: Equinix Singapore • 2015: 5-‐6 new exchanges in EU, 3-‐4 in USA, we are also looking at other places

4. Data-‐ vs. opinion-‐driven • Every change on the website is backed up by an experiment (A/B) • “We appreciate that you believe peering is faster, but if it really is, you should be able to prove it” • Set up tools, collect data before peering • Peer (the fun part) • Collect data again • Compare

5. Problems, challenges • Holiday desTnaTons are not the best places for good Internet connecTvity • Hotel partners have to use the admin interface to provide/update availability • Bookings via mobile devices from remote places • Our visitors don’t complain, if Booking.com is slow/doesn’t work, they just try other website

6. Tools and measurements • Latency • Page load Tme (both html-‐only and full-‐content) • Java script in users browsers fetching staTc objects from mulTple datacenters and reporTng data back • 4 Tier-‐1 transits (with really basic traffic engineering), AMS-‐IX and LINX connecTons

7. Results? Peering is NOT slower… …or we haven’t noTced it. SomeTmes it is indeed faster.

8. Latency • Not possible to check all peers, so we focused on search engines, eyeballs, ISP’s and colocaTons • About 300 world-‐wide desTnaTons examined • Small packets faster by 18,2 ms (15,2%), big packets by 18,7 ms (15,4%), including the data points with higher latency via peering • Search engines faster by 12-‐22% (depending on the service), Googlebot faster by 19%

9. HTML page load Tme, India HTML page load Tme, Thailand

10. StaTc object download Tme, Indonesia StaTc object download Tme, Bayan, Philippines

11. 3x staTc object download Tme, Telkom, South Africa StaTc object download Tme, Ooredoo, Qatar

12. HTML page load Tme, Romania HTML page load Tme, Serbia

13. StaTc object download Tme, Portugal Telecom, Portugal StaTc object download Tme, Switch, Switzerland

14. StaTc object download Tme, RCS & RDS, Romania StaTc object download Tme, Vega Telecom, Ukraine

15. Some observaTons • Shorter AS-‐path may mean EUàUSAàASIA • Hairpinning sTll happening in 2014 • Paths BookingàISPàDest rather rarely improved, so it is not that networks have congested uplinks • Paths BookingàISP1àISP2…àDest improved the more olen, the more ISP’s in the path • The bigger distance, the more latency to gain, the bigger advantages

16. Is peering really faster? • Latency is lower in most cases • Bemer page/object load Tme visible in some cases • Mostly stability/reliability improvements • More or less similar results could be possibly achieved by replacing some transits with others and very fine traffic engineering • “Faster” may also mean: less work needed to achieve bemer performance

17. QuesTons? Peer with AS43996!
