An Introduction to Prometheus (GrafanaCon 2016)Brian Brazil
Often what you monitor and get alerted on is defined by your tools, rather than what makes the most sense to you and your organisation. Alerts on metrics such as CPU usage which are noisy and rarely spot real problems, while outages go undetected. Monitoring systems can also be challenging to maintain, and overall provide a poor return on investment.
In the past few years several new monitoring systems have appeared with more powerful semantics and which are easier to run, which offer a way to vastly improve how your organisation operates and prepare you for a Cloud Native environment. Prometheus is one such system. This talk will look at the monitoring ideal and how whitebox monitoring with a time series database, multi-dimensional labels and a powerful querying/alerting language can free you from midnight pages.

Snabb Switch: Riding the HPC wave to simpler, better network appliances (FOSD...Igalia
By Katerina Barone-Adesi.
Driven by the needs of scientific computing, rapid rises in memory bandwidth have made it possible to implement high-performance network functions in a radically simpler way. Snabb Switch rides this wave, bypassing the kernel to process network packets in terse Lua, leaving the programmer free to focus on the essence of their problem. This talk presents our experiences delivering a carrier-grade implementation of "lightweight 4 over 6", an IPv4-as-a-service architecture that tunnels access to the IPv4 internet through specialized Snabb appliances.
We report on our recent experience implementing a carrier-grade virtualized network function, with observations on what it is like to build real-world, high-performance Snabb applications. (and kernel bypass). Each instance runs at essentially line speed on two ten-gigabit Ethernet cards.
Lightweight 4-over-6 (lw4o6) defines an IPv4-as-a-service architecture that allows ISPs to internally operate an IPv6-only network, tunneling IPv4 connections between lw4o6-aware endpoints installed at the customer's site (e.g. in OpenWRT) and an internet-facing "lwAFTR". Lw4o6 was specified in 2015 as RFC 7596 and has the architectural advantage that the carrier-side lwAFTR only needs per-customer state, not per-flow state. An lw4o6 system can also be configured to share IPv4 addresses between multiple customers as part of an IPv4 exhaustion strategy. It allows IPv4 networks to interoperate smoothly, while a carrier between them runs a pure-IPv6 network.
Igalia has built an open source "lwAFTR" implementation that is ready to deploy in production. We describe the joys of hacking with Snabb, giving a quick intro to Snabb, modern x86, and lw4o6 along the way.

Netty Notes Part 3 - Channel Pipeline and EventLoopsRick Hightower
Learning more about Netty helps me understand Vert.x better. Netty in Action is a great book. The threading model of Netty is very important to understanding event loops and reactive programming.
In this slide, we discussed the architecture of iptables and also showed how to implement your own IPTABLES module.
Upon the understanding of iptables, we implemented the DNS layer 7 parse in iptables module.
After that, we studied how Kubernetes service works and also explained why Kubernetes can't do layer7 load-balancer in TCP connection but UDP.
Monitoring a Kubernetes-backed microservice architecture with PrometheusFabian Reinartz
As many startups of the last decade, SoundCloud’s architecture started as a Ruby-on-Rails monolith, which later had to be broken into microservices to cope with the growing size and complexity of the site. The microservices initially ran on an in-house container management and deployment platform. Recently, the company has started to migrate to Kubernetes.
With the introduction of microservices, the existing conventional monitoring setup failed both conceptually and in terms of scalability. Thus, starting in 2012, SoundCloud invested heavily into the development of the open-source monitoring system Prometheus, which was designed for large-scale highly dynamic service-oriented architectures.
Migrating to Kubernetes, it became apparent that Prometheus and Kubernetes are a match made in open-source heaven. The talk will demonstrate the current Prometheus setup at SoundCloud, monitoring a large-scale Kubernetes cluster.

KubeCon EU 2016: Getting the Jobs Done With KubernetesKubeAcademy
When you hear words such as Kubernetes or OpenShift you immediately start thinking
about long running processes you can easily scale at will. However, Kubernetes includes a lesser known feature which allows you to run pretty much anything from simple tasks up to highly-complicated ones.
During this presentation, the author of the Job resource in Kubernetes will guide you through several techniques for performing anything ranging from simple Pi calculations to rendering a movie. No matter if you're a data scientist running large scale calculations across several data centers or a hobby programmer running simple day-to-day tasks, this presentation is to teach you how to efficiently use Kubernetes Jobs on their own or as the building blocks of something
bigger.
This presentation will feature a number of live demos to help illustrate the various ways that you can put Jobs to work. Don’t miss out on learning about one of the coolest features of Kubernetes!

Building Continuous Application with Structured Streaming and Real-Time Data ...Databricks
One of the biggest challenges in data science is to build a continuous data application which delivers results rapidly and reliably. Spark Streaming offers a powerful solution for real-time data processing. However, the challenge remains in how to connect them with various continuous and real-time data sources, guaranteeing the responsiveness and reliability of data applications.
In this talk, Nan and Arijit will summarize their experiences learned from serving the real-time Spark-based data analytic solutions on Azure HDInsight. Their solution seamlessly integrates Spark and Azure EventHubs which is a hyper-scale telemetry ingestion service enabling users to ingress massive amounts of telemetry into the cloud and read the data from multiple applications using publish-subscribe semantics.
They’ll will cover three topics: bridging the gap of data communication model in Spark and data source, accommodating Spark to rate control and message addressing of data source, and the co-design of fault tolerance Mechanisms. This talk will share the insights on how to build continuous data applications with Spark and boost more availabilities of connectors for Spark and different real-time data sources.
This talk was given at the Dutch PHP Conference 2011 and details the use of Comet (aka reverse ajax or ajax push) technologies and the importance of websockets and server-sent events. More information is available at http://joind.in/3237.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

2. What is Server Push?
• One of the features of HTTP/2
• Allows sending resources to a client before the
client requests them
• Avoids additional round trips
• May reduce time to first paint
• if we could use it wisely
3. How does it work?
Server Push
GET /index.html
GET /index.html
Client Intermediate Origin server
index.html
index.html
4. How can we use it on TS?
• TSHttpTxnServerPush
• Introduced since 7.0
• Experimental
• An example plugin is available
#include <ts/experimental.h>
void TSHttpTxnServerPush(TSHttpTxn txnp, const char *url, int url_len)
6. What will be a problem?
Server Push
GET /index.html
GET /index.html
?
We don’t know which resources we should push.
The client may already have the resource.
The push may delay the response from an origin.
7. What can we do?
• Use Manifest files
• Use Link header
• Use Link element in a HTML document
• Use Cache Digests (a.k.a CASPER)
• Also needs client side implementation
• Use AI (machine learning)
Simple
Complex
8. Future plan
• Add experimental plugins
• Add Server Push metrics (maybe 7.1.0)
• Brush up the API
• Show some results in the next summit
9. Summary
• Server Push MAY increase performance
• Server Push CAN decrease performance
• Server Push API is available since TS 7.0
• Server Push may be too complicated for human beings
WE NEED YOUR FEEDBACK!
