My name is Victor Perepelitsky I'm an R&D Technical Leader at LivePerson leading the 'Real Time Event Processing Platform' team.
In this Meetup I talked about the journey of creating the platform from scratch - challenges, design decisions, technology choices and more.
During the last 3 years the team has built Real Time Event Processing Platform which is currently running in production with thousands of new and migrated customers. It is built to handle hundreds of thousands requests per/sec with low latency response time (under 30 ms round trip)
I went through different topics and stages of this journey and share details that led to specific choices and results.
“Stateful or Stateless”, “CEP”, “Rules engine”, “Automated performance testing”, “Locking”, “Timing” were a part of the menu.
In this meetup, Kobi Salant - Data Platform Technical Lead & Vladi Feigin - Data System Architect, both from Liveperson will talk about : Making scale a non-issue for real-time Data apps.
Have you ever tried to build a system processing in real-time hundreds of thousands events per second and servicing more than 1M concurrent visitors?
We're going to talk about the LivePerson real-time stream processing solution doing exactly that. Learn how we empower digital call centers with insights for their critical decision making processes and never-ending efficiency goals.
In this Meetup Arik Lerner – Liveperson Team lead of Java Automation, Performance & Resilience , will talk about How we measure our services, By End2End testing which become one of the most critical Monitor tool in LP .

Zeebe itself is extremely fast, horizontally scalable, fault-tolerant and highly available. With Zeebe you can reliably processes all your transactions as they happen.
URP? Excuse You! The Three Metrics You Have to Know confluent
(Todd Palino, LinkedIn) Kafka Summit SF 2018
What do you really know about how to monitor a Kafka cluster for problems? Is your most reliable monitoring your users telling you there’s something broken? Are you capturing more metrics than the actual data being produced? Sure, we all know how to monitor disk and network, but when it comes to the state of the brokers, many of us are still unsure of which metrics we should be watching, and what their patterns mean for the state of the cluster. Kafka has hundreds of measurements, from the high-level numbers that are often meaningless to the per-partition metrics that stack up by the thousands as our data grows.
We will thoroughly explore three key monitoring concepts in the broker, that will leave you an expert in identifying problems with the least amount of pain:
-Under-replicated Partitions: The mother of all metrics
-Request Latencies: Why your users complain
-Thread pool utilization: How could 80% be a problem?
We will also discuss the necessity of availability monitoring and how to use it to get a true picture of what your users see, before they come beating down your door!

В условиях непрерывного роста сложности сетевой инфраструктуры и приложений, ИТ крайне необходим комплексный подход к мониторингу. С другой стороны, принимая во внимание, что больше половины рабочего времени ИТ тратит на расследование обращений конечных пользователей, важность именно проактивного мониторинга неоспорима. Но что делать, когда все выглядит хорошо, но пользователь продолжает жаловаться на плохую работу сети и приложений?

A Practical Guide to Selecting a Stream Processing Technology confluent
Presented by Michael Noll, Product Manager, Confluent.
Why are there so many stream processing frameworks that each define their own terminology? Are the components of each comparable? Why do you need to know about spouts or DStreams just to process a simple sequence of records? Depending on your application’s requirements, you may not need a full framework at all.
Processing and understanding your data to create business value is the ultimate goal of a stream data platform. In this talk we will survey the stream processing landscape, the dimensions along which to evaluate stream processing technologies, and how they integrate with Apache Kafka. Particularly, we will learn how Kafka Streams, the built-in stream processing engine of Apache Kafka, compares to other stream processing systems that require a separate processing infrastructure.

We have been talking about Serverless a lot lately and there are a couple of reasons for that. Serverless computing will provide greater scalability, more flexibility, and quicker time to release at reduced cost and this is the reason everybody is after it. Is serverless architecture enough to drive all this we talked about just now? The answer is no, of course. Also, State management has been absolutely challenging in serverless computing but Cloudstate will make it possible for us, wondering how? Keep reading the article until and you will learn it. The Lightbend’s Cloudstate which was released in August last year(2019) has proved to be a game-changer here as it provides stateful serverless computing, Cloudstate brings powerful new distributed and durable state management primitives based on Akka to the Serverless paradigm. Serving of stateful functions powered by Akka Cluster. That was all for the introduction, let’s talk about Cloudstate in detail below.
How Netflix Is Solving Authorization Across Their CloudTorin Sandall
Since 2008, Netflix has been on the cutting edge of cloud-based microservices deployments. In 2017, Netflix is recognized as one of the industry leaders at building and operating “cloud native” systems at scale. Like many organizations, Netflix has unique security requirements for many of their workloads. This variety requires a holistic approach to authorization to address “who can do what” across a range of resources, enforcement points, and execution environments.
In this talk, Manish Mehta (Senior Security Software Engineer at Netflix) and Torin Sandall (Technical Lead of the Open Policy Agent project) will present how Netflix is solving authorization across the stack in cloud native environments. The presentation shows how Netflix enforces authorization decisions at scale across various kinds of resources (e.g., HTTP APIs, gRPC methods, SSH), enforcement points (e.g., microservices, proxies, host-level daemons), and execution environments (e.g., VMs, containers) without introducing unreasonable latency. The presentation includes a deep dive into the architecture of the cloud native authorization system at Netflix as well as how authorization decisions can be offloaded to an open source, general-purpose policy engine (Open Policy Agent).
This talk is targeted at engineers building and operating cloud native systems who are interested in security and authorization. The audience can expect to take away fresh ideas about how to enforce fine-grained authorization policies across stackthe cloud environment.

After 16 years of solid use, the HTTP protocol finally got a major update this year. HTTP is the standard that defines how computers communicate over the Internet, and had not changed since 1999. The modern web, however, has become much more complex and HTTP/2 helps to address this brave new world.
Watch the webinar on demand: https://www.nginx.com/resources/webinars/whats-new-in-http2/
HTTP has a new specification (two actually) and has received a major overhaul of some of it's internals. While the protocol itself has not changed much, the transfer mechanism and other underlying systems have been completely re-worked. Adrian will expand on what has and has not changed, how to make the best use of it, and how to transition to the new standard if you need to.

HTTP colon slash slash: end of the road? @ CakeFest 2013 in San FranciscoAlessandro Nadalin
The HTTP protocol has been there for more than 20 years, almost untouched, but the current needs of the web are pushing towards adding some spices into the mix.
In this talk we will have a brief look at the history of HTTP, what SPDY - the "new" protocol proposed by google - brings into the table and how HTTP/2.0 will look like.
HTTP/2 comes to Java. What Servlet 4.0 means to you. DevNexus 2015Edward Burns
It’s hard to overstate how much has changed in the world since HTTP 1.1 went final in June of 1999. There were no smartphones, Google had not yet IPO’d, Java Swing was less than a year old… you get the idea. Yet for all that change, HTTP remains at version 1.1.
Change is finally coming. HTTP 2.0 should be complete by 2015, and with that comes the need for a new version of Servlet. It will embrace HTTP 2.0 and expose its key features to Java EE 8 applications. This session gives a peek into the progress of the Servlet spec and shares some ideas about how developers can take advantage of this exciting
update to the world’s most successful application protocol on the world’s most popular programming language.

An Introduction to the SIP protocol.
SIP Position in telecommunication networks and the content services.
What is SIP:
The Session Initiation Protocol (SIP) is a signaling communications protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP) networks.
The protocol defines the messages that are sent between peers which govern establishment, termination and other essential elements of a call. SIP can be used for creating, modifying and terminating sessions consisting of one or several media streams. SIP can be used for two-party (unicast) or multiparty (multicast) sessions. Other SIP applications include video conferencing, streaming multimedia distribution, instant messaging, presence information, file transfer, fax over IP and online games.

My name is Neta Barkay , and I'm a data scientist at LivePerson.
I'd like to share with you a talk I presented at the Underscore Scala community on "Efficient MapReduce using Scalding".
In this talk I reviewed why Scalding fits big data analysis, how it enables writing quick and intuitive code with the full functionality vanilla MapReduce has, without compromising on efficient execution on the Hadoop cluster. In addition, I presented some examples of Scalding jobs which can be used to get you started, and talked about how you can use Scalding's ecosystem, which includes Cascading and the monoids from Algebird library.

Check out Oren's recent blog post on the Subject: http://bit.ly/16i5lDS
Ofer Ron, senior data scientist at LivePerson.
Recently, I've had the pleasure of presenting an introduction to Data Science and data driven products at DevconTLV
I focused this talk around the basic ideas of data science, not the technology used, since I thought that far too many times companies and developers rush to play around with "big data" related technologies, instead of figuring out what questions they want to answer, and whether these answers form a successful product.
From a Kafkaesque Story to The Promised Land at LivePersonLivePerson
Ran Silberman, developer & technical leader at LivePerson presents how LivePerson moved their data platform from a legacy ETL concept to new "Data Integration" concept of our era.
Kafka is the main infrastructure that holds the backbone for data flow in the new Data Integration. Having that said, Kafka cannot come by itself. Other supporting systems like Hadoop, Storm, and Avro protocol were also integrated.
In this lecture Ran will describe the implementation in LivePerson and will share some tips and how to avoid pitfalls.

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).
