Presented by: Jeff Spahr Presented at the All Things Open 2021 Raleigh, NC, USA Raleigh Convention Center Abstract: Kubernetes has long since solved compute as a service, but what if you want to deploy higher level services without reimplementing the finer details of how to scale, cluster, and upgrade those services? Custom Resource Definitions (CRDs) allow users to expand the Kubernetes API to create resources like 'kind: elasticsearch' or 'kind: mariadb'. Operators manage those CRDs and take on orchestration and lifecycle management of those services. In this talk I'll cover the what and why of Operators on Kubernetes with a focus on what real world problems this solves for Kubernetes end users. I'll walk through deploying operators for common high level services that make up a production application. The XaaS walkthrough and demo will include some of the following technologies: * Cloud Services (EC2, S3) * Databases (MariaDB, Vitess, Elasticsearch) * Load balancers (F5, NGINX) * Streaming (Kafka, RabbitMQ) You'll leave this session with a foundation to start offering XaaS to your end users.

Microservice API Gateways with NGINX Slides from talk given on Tuesday August 2nd, 2017 at the Denver Open Source Users Group (DOSUG). (NGINX is pronounced "engine x".) Microservices are a popular architectural solution. Clients of microservices may experience some difficulty keeping track of the various instances and endpoints they have to call. An API gateway can help manage large numbers of microservices and hide the infrastructure complexity from your clients. We will review a microservice architecture before and after the addition of an API gateway. An API gateway is a reverse proxy. A reverse proxy handles incoming requests from clients and calls a service to get the data to satisfy that request. The reverse proxy returns that data to the client. Many developers write these proxies by hand in custom code, not realizing there better solutions available. We will mention a number of popular solutions, some open source and some cloud-based services. For this talk, we will focus on NGINX, a popular open source reverse proxy and API Gateway. (NGINX also sells an enterprise offering, NGINX Plus, but this talk will only cover the features available in the open-source version.) We will show how to set up NGINX as an API Gateway. We will dive into the configuration and operation of NGINX.

Serverless Computing 2019, November 2019, London: Talk by Mario-Leander Reimer (@LeanderReimer, Principal Software Architect at QAware) === Please download slides if blurred! === Abstract: Knative is a K8s based platform to build, deploy, manage and run serverless workloads. In this session we will take a look at the concepts of each Knative building block and apply them directly in practice. First, we’ll define and use Tekton pipelines to build our workloads. Then we’ll use Knative serving to rapidly deploy serverless containers with automatic scaling up and down to zero. Finally, we’ll show how to build loosely coupled event-driven architectures with the help of Knative eventing. This session will also cover the different installation options leveraging either Istio or the API gateways Gloo and Ambassador.

SpringOne Platform 2017 Ramiro Salas, Pivotal The concept of a service mesh represents a paradigm shift on application connectivity for distributed systems, with wide implications for analytics, policy and extensibility. In this talk, we will explain what a service mesh is, the power it brings to microservices, and its impact on Cloud Foundry and K8s, both separately and together. We will also discuss the implications for the traditional network infrastructure, and the shifting of responsibilities from L3/4 to L7, and our current thinking of using Istio to integrate all abstractions.

At JCPenney, Black Friday is one of our most critical shopping periods, both in stores and increasingly online. Hundreds of millions of dollars are on the line for us in a narrow shopping window so scaling to handle the traffic and being able to deploy promotions and fix issues without disruption to the website and our business are critical. Our prior way of delivering applications was built on a waterfall model, locked in to a set of ISV vendor dependencies, with rigid silos. It was too slow and expensive to deploy changes and keep pace with our business. We needed an application delivery platform that can handle the scale of Black Friday, and allow us to adapt our systems as our business continues to evolve. In our DockerCon session, we will tell you how we are transforming JCPenney’s omnichannel business with Docker and open solutions like Jenkins, Spring cloud, Netflix OSS and Ansible. We went live in our first iteration in just two months, and then on-boarded over 30 services in the first 6 months. We learned quite a bit along the way and you'll hear why we made an important decision to switch from Docker Community Edition to Docker Enterprise Edition. Our new cloud-native, Dockerized systems handle over 100,000 deployments per year and can scale to handle events like Black Friday with zero issues.

Microservice 4.0 Journey - From Spring NetFlix OSS to Istio Service Mesh and ...

Daniel Oh

Companies looking to speed up their software development are adopting microservices architectures (MSA). Building applications as groups of smaller components with fewer dependencies helps companies such as Comcast, Capital One, Uber, and Netflix deliver more frequent releases and thus innovate faster. An important consideration in adopting an MSA is deciding how individual services should communicate between each other. Adding a message queue such as RabbitMQ to handle interservice messages can improve communication by: - Simplifying our services so they only need to know how to talk to the messenger service. - Abstracting communication by having the messenger service handle sophisticated orchestration patterns. - Scaling message throughput by increasing the cluster size of the messenger service. In this webinar we'll discuss: - Requirements for communicating between microservices - Typical messaging patterns in microservice architectures - Use cases where RabbitMQ shines - How to use the RabbitMQ service for Pivotal Cloud Foundry to deploy and run your applications We’ll also demonstrate how to deploy RabbitMQ in Pivotal Cloud Foundry, and how to incorporate it in microservices-based applications.

Companies need to build better software faster to compete. But existing monolithic applications, legacy platforms, and lengthy operational deployment cycles are holding innovation back. Microservices are becoming the cloud architecture of choice because they offer the ability to loosely couple applications into discrete services that can be surgically changed without requiring disruptive overhauls. This approach enables the responsiveness and rapid change needed by the business. Enterprise PaaS is a critical foundation to simplify the operations, governance, and health management of these new architectures. Together with a DevOps culture, microservices and PaaS are the engine that drives innovation at speed.

The large scale of the challenge for application writers exploiting cloud and DevOps is clearer, but so is the path forward. Understanding the DevOps approach is important, but equally you must understand specific deployment technologies, security issues, operational reliability, and how to drive organisational transformation. Whether creating simple applications or sophisticated microservice architectures many of the challenges are the same. Join us to learn how you can apply this within your team and company.

Domain-Driven Design changed the way we reason about large software systems. Modern practices, tools and technologies like continuous delivery, NoSQL, and cloud-based virtualization allow the creation of fine-grained systems to solve the specific problems at hand. Having DDD in mind and technical expertise at our hands, with Microservice architectures we can build complex systems that reflect our businesses' complex realities and are easy to change at the same time. This talk will show what DDD and Microservice architectures have in common and how you can use both to create software systems that fit your domain.

DDD / Microservices @ Trivento Spring Camp, Utrecht, 2015

Dennis Traub

Microservice architecture is a new way of developing an application as a suite of independently deployable and manageable small services talking to each other using web services(REST) or a message broker(AMQP). While there is no precise definition and others consider microservices to be simply an ideal, refined form of SOA(Service-oriented architecture ), each microservice should be relatively small so that it's easier for a developer to understand, use suitable framework and IDE, deploy, scale, easily isolate fault.

As presented at Cloud Foundry Summit 2015 in Santa Clara, CA. Now that you have Cloud Foundry, what are you going to do with it? This presentation will show using Spring Cloud on Cloud Foundry to quickly leverage common microservice patterns, including distributed configuration management, service discovery, intelligent routing, load balancing, and fault tolerance. Using Spring Cloud on Cloud Foundry, developers can take advantage of the cloud native microservice architectures pioneered by those building the web at places like Twitter, LinkedIn, and Netflix. In many cases they can do so running the same code with Spring Cloud wrapping the same battle-tested open source components those companies are running in production.

Audience: Beginner About: As OpenStack gains traction in today’s enterprise environments, other cloudy concepts are beginning to take hold in enterprises as well. Today’s enterprises are transitioning from waterfall to agile, more interested in DevOps, and are adopting programmable infrastructure faster than ever before. To maximize returns on the investments today’s enterprises are making, IT departments need to learn new skills and new concepts. Infrastructure as Code (IAC) is one of those concepts that everyone hears a lot about, but in many cases, it is not well understood. Appdevs need to learn infrastructure, infrastructure teams need to learn software development strategies. Bridging the gaps between the two teams can drive the overall consumption of an OpenStack cloud. This session will discuss the basic concepts of infrastructure as code and how to get started. We will also review what it takes to get started (Software repositories, Version Control, etc) and strategies for selling your cloud. Speaker Bio: Steve Tegeler – Director of Systems Engineering, VMware Steve currently leads a team of experts who help customers deploy OpenStack in their organizations. Over the last 10 years Steve has spent a tremendous amount of time with IT departments making choices around IaaS. Steve came to VMware through the acquisition of Nicira. At Nicira, Steve spent time not only on Network & Security virtualization, but the overall automation strategy. He’s seen a lot of success, and also a lot of failures. Speaker Bio: Nathan Ness – Staff Systems Engineer, VMware Nathan Ness has been a part of the Networking and Security Business Unit at VMware since the acquisition of Nicira. His background includes datacenter networking and security with an emphasis in cloud and virtualization technologies. Currently at VMware he focuses on anything & everything related to OpenStack + VMware. He holds certifications in Cisco, Microsoft, and VMware NSX.

The adoption of microservices add a new layer of complexity to an already complex application environment. When application issues arise, it becomes difficult to pinpoint the source and, too often, you find yourself in lengthy war rooms or assigning experts to triage every issue. As a result, brand loyalty, customer satisfaction and innovation are negatively impacted. The old approach to monitoring application performance just isn’t working. A new approach is needed. In this session we will discuss four areas that you should consider which will change the way you think about monitoring microservices

Scalable TensorFlow Deep Learning as a Service with Docker, OpenPOWER, and GPUs

Indrajit Poddar

In most current microservice-based architectures, the machine images powering the microservice are quite traditional: a full software stack from operating system to application, which takes significant resources to host and plenty of time to start and stop. As a result, most current microservice workloads are persistent, having to start before they are needed and sitting idle when there’s no work to do. This wastes precious resources and slows the application’s ability to scale out as workloads require. The arrival of lightweight technologies like Docker and containers have opened the door to lighter workloads in the microservice arena, but the advent of unikernels might be a game changer. These ultralight, highly secure workloads combine the entire software stack—from operating system functions to application—into a single, tiny package that runs directly on a hypervisor. Start times for many unikernel-based VMs can be measured in milliseconds, raising the question: why waste time and resources with persistent microservices? Why not consider transient microservices, which appear when there is something to do and disappear immediately thereafter? While the use of transient microservices could free up much computing power, it will also change the architecture and orchestration of software solutions. The concept of services that may have a lifetime measured in seconds—or less—does not currently exist in popular cloud-based systems.

Developing and running web applications has become much more than just writing code. Business and engineers are now required to solve a new set of challenges which range from microservices architectures to set up software delivery pipelines, while releasing constantly new features. In this context, automation is key. With Container-based architectures and Kubernetes we are on the verge of a copernican revolution in the way we handle operations and design our applications. The so called Cloud-Native stack open doors to unprecedented resilience, scalability and efficiency but the price to pay is complexity: Containers are a fundamental shift which require to re-think how components of your applications and infrastructure are developed and deployed. In this talk we discussed the Domain specific concepts that power Kubernetes and how they apply to Magento. We immersed ourselves deeply on the architectural choices and challenges of running a production ready Magento deployment on Kubernetes and we will see hands-on how to fully automate the deployment lifecycle, web applications scaling (reducing scaling time from minutes to seconds), failures handling and self-healing.

How Workday manage stateful services with a custom controller on Kubernetes? Conference talk for CloudNative London 2018 https://skillsmatter.com/skillscasts/12106-evolving-services-into-the-cloud-native-world-how-workday-manage-stateful-services-with-a-custom-controller-on-kubernetes Kubernetes and declarative infrastructure greatly simplify the way we deploy and manage software. Most services can be orchestrated with the control loops supplied by Kubernetes (deployments, stateful sets or jobs). Some stateful services in Workday require more advanced orchestration, and re-architecting them is not an easy option. In this talk you will discover why some of our services require extra orchestration, and how we evolved an existing service into a control loop on top of Kubernetes. The control loop organises multiple services into groups these are dynamically created, deleted and scaled. It also orchestrates blue/green deployments of each group. Now we can adopt more kubernetes features and retire some of our old scheduling code. Finally you will learn the process we follow to evaluate and design our own control loops and when you might find them useful. Bio Iain is a principal software engineer at Workday using Kubernetes and Scala to deliver their next generation elastic grid. His twin passions are large scale distributed computing and applying clean code to complex problems. He is interested in good design and how this can improve system reliability and reduce friction during development. He loves sharing his experiences as he learns and builds new systems. He regularly speaks at local meetups in Dublin and has presented at conferences including GotoConf, Scala Days, Functional Kats and Lambda World.

Kafka is an open-source distributed commit log addressing low latency, high throughput, scalability, fault-tolerance, and disk-based retention. It can be used to build tracking systems, messaging systems, high performance streaming platforms, real-time analysis, audit log….you name it. In our case, it’s been used to build a scalable event-store and messaging platform that stores billions of messages. In this talk, we’re taking a closer look at essential Kafka concepts such as partition rebalancing, offset management, replication, producer/broker request fetching, file segments, etc. to understand what makes Kafka so scalable, resilient, performant and fault tolerant. We will also touch upon Kafka transactions to know what they are and how to leverage them. Last but not the least we will highlight some potential pitfalls that one should watch out when going to production with Kafka.

Slides from my presentation at O'Reilly Software Architecture 2018, co-presented with Allard Buijze. Much hyped architectural pattern CQRS is getting a lot of attention, but it does actually deliver on its promises of managing complexity and scalability when used with the right abstractions. Casumo, a Malta-based online casino, adopted the principles of CQRS based on these promises. As the company scaled to hundreds of employees and over a hundred services, these promises were put to the challenge. Allard Buijze and Nakul Mishra discuss the challenges Casumo faced while scaling its system to millions of financial transactions per day and applying event sourcing with billions of events to keep up with the ever-changing demands of the gaming industry.

Scaling CQRS in theory, practice, and reality

There's a ton of theory available on DDD, event sourcing and CQRS but how does one get's started in terms of code? Moreover, when we have a tight deadline, one wants to solely focus on solving core business problems rather than getting caught up by plumbing non-functional concerns such as snapshotting, command handling, guaranteed events delivery to the right event listeners, events replaying, persisting aggregate, etc. In this talk, we will build an application to see how Axon Framework supports CQRS and Event sourcing by providing a robust implementation for fundamental building blocks such as event dispatching mechanism, aggregates, repositories, event sourcing, Domain Events, etc.to build scalable, extensible and maintainable applications. Furthermore, Axon provides extensive support for Spring which means much of the configuration can be avoided by leveraging Spring's annotation support.

The presentation explored the complexities of enterprise search challenges and how IA principles can be leveraged to provide AI solutions through the use of a semantic layer. O’Brien-Scott and Cakici showcased a case study where a taxonomy, an ontology, and a knowledge graph were used to structure content at a healthcare workforce solutions organization, providing personalized content recommendations and increasing content findability. In this session, participants gained insights about the following: Most common types of AI categories and use cases; Recommended steps to design and implement taxonomies and ontologies, ensuring they evolve effectively and support the organization’s search objectives; Taxonomy and ontology design considerations and best practices; Real-world AI applications that illustrated the value of taxonomies, ontologies, and knowledge graphs; and Tools, roles, and skills to design and implement AI-powered search solutions.
