Apache Spark is the next-generation distributed computing framework, rapidly becoming the de facto standard for big data analytics. It provides rich, expressive APIs in multiple languages, including Scala, Java, Python, and R. However, depending on the use case—a data scientist working in an Jupyter Notebook or a data engineer implementing long-running Spark submit jobs—choosing the right language can be a dilemma. This session uses a Spark application that performs “sentiment analysis of Twitter data” to compare and contrast the feature differences between the languages, API coverages, and overall productivity. With concrete examples, it provides insight to help you decide when to use Scala, Java, Python, or perhaps a mix of these.

Many marketplace products (e.g pricing, positioning etc.) in Uber require intensive realtime optimizations. Such applications help Uber automatically maintain marketplace reliability, generate market insights and improve the network efficiency across more than 600 cities in realtime. Underneath, Uber engineers leverage Apache Flink to build a platform that not only runs compute intensive optimization models, but also very quickly reacts to rapid changes in marketplace. In this talk, I will cover the compute platform that leverages Apache Flink to i.) aggregate billions of realtime and forecasted demand and supply level information across the globe. ii.) trigger on-demand optimization models to respond to changes in marketplace and iii.) scale both horizontally and vertically as we expand the platform to onboard new applications and experiences.

"It’s not only Lambda! Economics behind Serverless" at Serverless Architectur...Vadym Kazulkin
When we talk about prices, we often only talk about Lambda costs. But we rarey use only Lambda in our applications. Usually, we have other building blocks like API Gateway, data sources like SNS, SQS or Kinesis and Log service (Cloud Watch). Also, we store our data either in S3 or in serverless databases like DynamoDB or recently in Aurora Serverless. All these services have their own price models which we have to pay attention to. Moreover, we have to consider application data transfer costs. In this talk, we will draw the complete picture about the costs in the serverless applications, look at the Total Cost of Ownership and make some recommendations about when it’s worth using serverless and when the traditional approach (EC2)

FaaS composition using Kafka and Cloud-Events
LOCATION: Burton & Redgrave, DATE: November 7, 2019, TIME: 2:30 pm - 3:15 pm
https://serverlesscomputing.london/sessions/faas-composition-using-kafka-and-cloud-events/
Serverless functions or FaaS are all the rage. By leveraging well established event-driven microservice design principles and applying them to serverless functions we can build a homogenous ecosystem to run FaaS applications.
Kafka’s natural ability to store and replay events means serverless functions can not only be replayed, but they can also be used to choreograph call chains or driven using orchestration. Kafka also means we can democratize and organize FaaS environments in a way that scales across the enterprise.
Underpinning this mantra is the use of Cloud Events by the CNCF serverless working group (of which Confluent is an active member).
Objective of the talk
You will leave the talk with an understanding of what the future of cloud holds, a methodology for embracing serverless functions and how they become part of your journey to a cloud-native, event-driven architecture.

Event-Driven Stream Processing and Model Deployment with Apache Kafka, Kafka ...Kai Wähner
Talk from Kafka Summit San Francisco 2019 (https://kafka-summit.org/sessions/event-driven-model-serving-stream-processing-vs-rpc-kafka-tensorflow/). Video recording will be available for free on the Summit website.
Event-based stream processing is a modern paradigm to continuously process incoming data feeds, e.g. for IoT sensor analytics, payment and fraud detection, or logistics. Machine Learning / Deep Learning models can be leveraged in different ways to do predictions and improve the business processes. Either analytic models are deployed natively in the application or they are hosted in a remote model server. In the latter you combine stream processing with RPC / Request-Response paradigm instead of direct doing direct inference within the application. This talk discusses the pros and cons of both approaches and shows examples of stream processing vs. RPC model serving using Kubernetes, Apache Kafka, Kafka Streams, gRPC and TensorFlow Serving. The trade-offs of using a public cloud service like AWS or GCP for model deployment are also discussed and compared to local hosting for offline predictions directly “at the edge”.
Key takeaways
• Machine Learning / Deep Learning models can be used in different ways to do predictions. Scalability and loose coupling are important success factors
• Stream processing vs. RPC / Request-Response for model serving has many trade-offs – learn about alternatives and best practices for your different scenarios
• Understand the alternatives and trade-offs of model deployment in modern infrastructures like Kubernetes or Cloud Services like AWS or GCP
• See live demos with Java, gRPC, Apache Kafka, KSQL and TensorFlow Serving to understand the trade-offs

Cassandra Summit 2014: Apache Spark - The SDK for All Big Data PlatformsDataStax Academy
Apache Spark has grown to be one of the largest open source communities in big data, with over 190 developers and dozens of companies contributing. The latest 1.0 release alone includes contributions from 117 people. A clean API, interactive shell, distributed in-memory computation, stream processing, interactive SQL, and libraries delivering everything from machine learning to graph processing make it an excellent unified platform to solve a number of problems. Apache Spark works very well with a growing number of big data solutions, including Cassandra and Hadoop. Come learn about Apache Spark and see how easy it is for you to get started using Spark to build your own high performance big data applications today.
Apache Spark has emerged over the past year as the imminent successor to Hadoop MapReduce. Spark can process data in memory at very high speed, while still be able to spill to disk if required. Spark’s powerful, yet flexible API allows users to write complex applications very easily without worrying about the internal workings and how the data gets processed on the cluster.
Spark comes with an extremely powerful Streaming API to process data as it is ingested. Spark Streaming integrates with popular data ingest systems like Apache Flume, Apache Kafka, Amazon Kinesis etc. allowing users to process data as it comes in.
In this talk, Hari will discuss the basics of Spark Streaming, its API and its integration with Flume, Kafka and Kinesis. Hari will also discuss a real-world example of a Spark Streaming application, and how code can be shared between a Spark application and a Spark Streaming application. Each stage of the application execution will be presented, which can help understand practices while writing such an application. Hari will finally discuss how to write a custom application and a custom receiver to receive data from other systems.

Why Kubernetes as a container orchestrator is a right choice for running spar...DataWorks Summit
Building and deploying an analytic service on Cloud is a challenge. A bigger challenge is to maintain the service. In a world where users are gravitating towards a model where cluster instances are to be provisioned on the fly, in order for these to be used for analytics or other purposes, and then to have these cluster instances shut down when the jobs get done, the relevance of containers and container orchestration is more important than ever.
Container orchestrators like Kubernetes can be used to deploy and distribute modules quickly, easily, and reliably. The intent of this talk is to share the experience of building such a service and deploying it on a Kubernetes cluster. In this talk, we will discuss all the requirements which an enterprise grade Hadoop/Spark cluster running on containers bring in for a container orchestrator.
This talk will cover in details how Kubernetes orchestrator can be used to meet all our needs of resource management, scheduling, networking, and network isolation, volume management, etc. We will discuss how we have replaced our home grown container orchestrator with Kubernetes which used to manage the container lifecycle and manage resources in accordance to our requirements. We will also discuss the feature list as container orchestrator which is helping us deploy and patch 1000s of containers and also a list which we believe need improvement or can be enhanced in a container orchestrator.

Data Centers - Striving Within A Narrow Range - Research Report - MCG - May 2...pchutichetpong
M Capital Group (“MCG”) expects to see demand and the changing evolution of supply, facilitated through institutional investment rotation out of offices and into work from home (“WFH”), while the ever-expanding need for data storage as global internet usage expands, with experts predicting 5.3 billion users by 2023. These market factors will be underpinned by technological changes, such as progressing cloud services and edge sites, allowing the industry to see strong expected annual growth of 13% over the next 4 years.
Whilst competitive headwinds remain, represented through the recent second bankruptcy filing of Sungard, which blames “COVID-19 and other macroeconomic trends including delayed customer spending decisions, insourcing and reductions in IT spending, energy inflation and reduction in demand for certain services”, the industry has seen key adjustments, where MCG believes that engineering cost management and technological innovation will be paramount to success.
MCG reports that the more favorable market conditions expected over the next few years, helped by the winding down of pandemic restrictions and a hybrid working environment will be driving market momentum forward. The continuous injection of capital by alternative investment firms, as well as the growing infrastructural investment from cloud service providers and social media companies, whose revenues are expected to grow over 3.6x larger by value in 2026, will likely help propel center provision and innovation. These factors paint a promising picture for the industry players that offset rising input costs and adapt to new technologies.
According to M Capital Group: “Specifically, the long-term cost-saving opportunities available from the rise of remote managing will likely aid value growth for the industry. Through margin optimization and further availability of capital for reinvestment, strong players will maintain their competitive foothold, while weaker players exit the market to balance supply and demand.”
Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.
