Building resilient and scalable API backends with Apache Pulsar and Spring Reactive
Lari Hotari

Reactive style of programming can simplify service composition in API backends built for massive scale. A reactive microservice should be able to use reactive APIs for the end-to-end processing of an API request. A reactive interface to a pub-sub messaging system is a common gap. This talk demonstrates a solution where the pub-sub messaging system, Apache Pulsar, is part of the full end-to-end reactive solution for building resilient and highly scalable API backends.
It is demonstrated in the context of a sample Spring Boot API backend how the Apache Pulsar Java Client can be adapted to Reactive Streams so that the full extent of Spring Reactive can be leveraged for error handling and improving resilience by using features such as reactive non-blocking backpressure, timeout handling, circuit breakers, retries and rate limiting.

Lari Hotari is a Apache Pulsar committer and Senior Software Engineer at DataStax. He has worked on the Java platform since 1997 and has contributed to open source for over 20 years.

Micro services using Apache sling
Dr Yash Mody

As we progress towards low code and no code application behaviour, Apache Sling is uniquely positioned to create microservices that Martech teams can create and control with great ease. The OAS 3 compatible OSGi module, Apache Shiro security layer and an API gateway using the Apache webserver make it a robust platform. JCR node structure adapts to the Restful API philosophy. A layer of messaging using Kafka, using zookeeper to manage HA, ingesting API statistics to create an ai layer that can allow the API access to be modulated and optimised.

Yash has been an avid proponent of Open Source software. He handles the online platform for several banks and e-commerce platforms. He is currently focused on building his no code api platform “SHAFT” based on Apache Sling and other Apache tech stack products.

Introduction to AsyncAPI for Apache Kafka
Lorna Mitchell

Apache Kafka is such a powerful and flexible way of streaming events and data, and can accommodate an unending variety of data types and structures, in a variety of formats. This great feature can also be a bug when you're integrating with yet another completely different stream of data!
Enter AsyncAPI, an open standard for describing records in event-driven systems. Using AsyncAPI you can clearly describe the data payloads and transform that information into developer-friendly documentation; other tools can validate AsyncAPI and generate code for clients or integrations. In this session you will see "behind the curtain" of how the AsyncAPI document is structured, and get a demo of some of the tools that build on AsyncAPI to build things like documentation and example code. If you aren't using AsyncAPI already, and your Kafka talks to other systems, then you'll want to see this talk.

Lorna is based in Yorkshire, UK; she is a Developer Advocate at Aiven as well as a published author and experienced conference speaker. She brings her technical expertise on a range of topics to audiences all over the world with her writing and speaking engagements. Lorna has a strong background in open source, and a passion is for better Developer Experiences for developers everywhere. You can find out more about Lorna on her website https://lornajane.net.

A high-security API management infrastructure using Apache Camel
Yang Xie

Apache Camel is usually thought to be an integration tool to integrate the disparate systems. In addtion, it also suitable for an API management infrastructure. However, when it is used as an API management infrastructure, there is still a security drawback because it cannot do Access Control such as Token Introspection and Scope Check. In this presentation, we take the challenge to propose a high-security API management infrastructure that is mainly constructed with Camel and Keycloak (An Identity and Access Management tool based on OAuth2.0/OIDC) to resolve the drawback.
Our proposal provides the following features: Token Issuance and Management based on OAuth 2.0, Integration with external IdP, Reverse Proxy, Access Control (Token Introspection, Scope Check and OAuth MTLS), Flow Control, Metrics (should work with other components like Prometheus), API Specification Publishing, and some features support the API creation like Protocol Conversion and Mash-up.

Yang Xie is a software engineer at Hitachi, Ltd. He is engaged on the technical support for Keycloak, 3scale, and Apache Camel. And he is also an open source contributor for Keycloak.

Apache Flink StateFun: A Platform-Independent Stateful Serverless Stack
Tzu-Li (Gordon) Tai

Stateful Functions (StateFun), a project developed under the umbrella of Apache Flink, provides consistent messaging and distributed state management for stateful serverless applications. It does so in a vendor, platform and language agnostic manner - applications are composed of inter-messaging, polyglot functions that can be deployed on a mixture of your preferred FaaS platforms, as a Spring Boot application on Kubernetes, or really any deployment method typically used in modern cloud-native architectures.
In this session, you will learn about the core concepts behind the project and the abstractions that developers would work with, all up to date to the latest 3.0 release. For new users, the content of this talk will be a perfect place to get started with StateFun. For existing users, this will be a great opportunity to catch up with the latest advancements in the project, including improved ergonomics around zero-downtime upgrade capabilities of StateFun applications, type system for messages and function state, as well as an extended array of new language SDKs.

Scaling Betfair Exchange to support 160k rps using Apache Kafka
Manjunath Shivakumar

On the Betfair Exchange, our biggest customers trade at ultra high frequencies pouring in millions of GBP on high profile sporting events into our trading systems. As such, low latency and reliability is key to everything we build. Our customers need to be able to view the current positions on offer on a market, place their orders accordingly and see them fulfilled reliably, all of which needs to happen in a few milliseconds. As an ever expanding company, we also have a steady growth in a number of jurisdictions we operate in, so the number of customers operating at such frequencies are going up every single day. All this means we need our exchange trading platform to be resilient, reliable, fast and easily scalable. On a busy Saturday afternoon when there is popular football going on, we see in excess of 200k transactions per second across our estate, and 99.9% of them being served with an SLA of 10ms. This used to be about 40k transactions per second a few years ago, but the goal post is constantly moving for us. So in order to get from that point to the present day, we needed to fundamentally re-engineer our backend systems, to be largely event driven, and Apache Kafka was the perfect tool to help us solve this problem. We are also currently in the middle of rearchitecting the core of our exchange platform that accepts new orders and fulfills them in a matter of few milliseconds. Whilst a transactional RDBMS has performed this function reliably for us for many years, its time to move this onto next generation of fast, reliable, distributed and scalable interface. This presentation details some of the challenges we faced and how we overcame them, to re write the core of exchange using Apache Kafka, essentially pumping millions of GBP trades everyday through a central backbone built around Apache Kafka.

Manjunath Shivakumar has worked on the Betfair Exchange for nearly a decade evolving it from a monolithic system with limited scalability to a fully event driven micro service based architecture today where we are able to support in excess of 200k requests per second. Manjunath started as a developer working on some core areas of the exchange and am now responsible for driving the future direction of the exchange as the architect. Manjunath presents regularly at company internal meetups and have presented externally in prestigious conferences like Kafka Summit. Manjunath would love the opportunity to present our journey to a more global audience at the Apache Con 2021.

Practice of Apache APISIX in Low-Code Gateway
Zhiyuan Ju

Apache APISIX is a cloud-native, high-performance, fully dynamic API gateway. As a traffic portal, it provides rich traffic management capabilities: on the one hand, it ensures stable and reliable upstream services under high traffic conditions; on the other hand, combined with a flexible plug-in mechanism, it realizes fine-grained traffic control, integrates common business solutions, and user authentication services that used to be implemented in multiple upstream services can now be unified at the gateway level through Apache APISIX. This greatly reduces the development work of repeated common services. In addition, Apache APISIX is the first low-code API gateway that enables users to assemble plug-ins by dragging and dropping and generate DSLs for the gateway to handle, enabling plug-ins to create plug-ins! Today, I will share with you the problems and accumulated experience of Apache APISIX in the direction of implementing a low-code gateway.

Zhiyuan Ju is anApache APISIX PMC, ApacheCon Speaker (2020), and core member of freeCodeCamp.

Pulsar Beam, HTTP streaming over Apache Pulsar
Ming Luo

To enable language and OS agnostic Pulsar clients, we answer the call to build a service to enable producing and consuming events via HTTP. It offers an HTTP endpoint for message ingestion, an HTTP SSE interface for event streaming as consumer, and a push notification based webhook interface. The design, which is implemented in Golang, keeps Cloud Native in mind. Key components are stateless and can be deployed independently for scalability.
By supporting webhooks, Pulsar Beam is able to tap into Major cloud providers. It extends the reach of Pulsar to the entire AWS, Azure, and GCP’s ecosystem via Lambda, Azure and GCP function integration.

Ming is a software engineer at DataStax. He was co-founder of Kesque that offered Pulsar as SaaS product. Prior to that, he has been building large scale real time and distributed software for IBM, Ericsson, and Nortel.

OGC APIs: A Suite of Web API Standards for Handling and Exchanging Location Data
Gobe Hobona, Scott Simmons

Many software libraries, including open source ones, include an ability to handle location data. In several cases, when standards are not followed, the software libraries mishandle location data leading to errors in positioning or loss of information. In some cases, the mishandling occurs at the API or microservice tier due to inconsistencies in how the APIs represent location data. Recognising this increasingly serious issue, the Open Geospatial Consortium (OGC) has embarked on a standardisation program to develop the OGC API suite of standards. This suite of standards defines modular API building blocks that spatially enable Web APIs in a consistent way. The proposed presentation will introduce the OGC API suite of standards and describe how various Apache Software Foundation projects could leverage the API standards.
The OGC is an international consortium of more than 500 businesses, government agencies, research organizations, and universities driven to make geospatial (location) information and services FAIR - Findable, Accessible, Interoperable, and Reusable. The consortium provides a consensus process for collaborative development, approval and maintenance of open, international standards that make location information FAIR – Findable, Accessible, Interoperable, and Reusable. It is through this process that the consortium is developing a series of OGC API standards for handling and exchanging Web APIs.

Gobe Hobona:
