Service Mesh @Lara Camp Myanmar - 02 Sep,2023

At AWS re:Invent, we have launched support for blue/green deployments for services hosted using AWS Fargate and Amazon Elastic Container Service (Amazon ECS). Blue/green deployments help you minimize downtime during application updates. They allow you to launch a new version of your application alongside the old version and test the new version before you reroute traffic to it. You can also monitor the deployment process and, if there is an issue, quickly roll back. In this workshop, you will create a new service in AWS Fargate that uses AWS CodeDeploy to manage the deployments, testing, and traffic cutover for you.

Cilium is open source software for providing and transparently securing network connectivity and load balancing between application workloads such as application containers or processes. Cilium operates at Layer 3/4 to provide traditional networking and security services as well as Layer 7 to protect and secure use of modern application protocols such as HTTP, gRPC and Kafka. The foundation of Cilium is the new Linux kernel technology BPF which supports the dynamic insertion of BPF bytecode into the Linux kernel at various integration points. This presentation reveals the secrets of Kubernetes networking and gives you a deep dive into Cilium and why it is awesome!

This deck covers Kubernetes abstractions, design patterns, integrations and extensions. These features simplifies Devops.

The Cilium project is a popular networking solution for Kubernetes, based on eBPF. This talk uses eBPF code and demos to explore the basics of how Cilium makes network connections, and manipulates packets so that they can avoid traversing the kernel's built-in networking stack. You'll see how eBPF enables high-performance networking as well as deep network observability and security.

Istio Service Mesh for Developers and Platform Engineers (Presented at Singapore k8s user group 23-May-2023)

This document discusses the current and future state of service mesh. It provides an overview of Solo.io, including its leadership team members and growth. It then discusses key functions of service meshes like Istio including traffic control and policy enforcement. The document outlines considerations for extending the data plane, such as with GraphQL and eBPF. It argues that optimizing the data plane is an area of ongoing innovation and discusses tradeoffs between different data plane architectures.

Presented at Spacewalk 2023 Presented by Christian Posta, solo.io Title: The Future of Service Mesh Abstract: Service mesh is a powerful way to solve cross-cutting application-networking concerns, such as load balancing, service resilience, observability, and security. Adopting a mesh for your services can save hundreds of hours of developer time and reduce the burden placed on operations. In this talk we'll explore some common use cases for service mesh, look at some case studies, and then dig into innovation happening in this space such as "sidecar-less" service mesh.

Patomphon Vimolket introduces Cisco's vision for enabling next-generation data center transformations through software-defined technologies. The document discusses challenges like evolving threats, manual operations, and digital disruption. It presents Cisco's data center reference architecture and portfolio including Cisco CloudCenter, Nexus, UCS, HyperFlex, ACI, Intersight, and security solutions like Tetration and AppDynamics. These provide application visibility, infrastructure optimization, and security to help businesses adapt to challenges like multicloud, microservices, and more dynamic environments.

Developing and managing hundreds (or maybe thousands) of microservices at scale is a challenge for both development and operations teams. We have seen over the last years the appearance of new frameworks dedicated to deliver ‘Cloud Native’ applications by providing a set of (out of box) building blocks. Most of these frameworks integrate microservices concerns at the code level. Recently, we have seen the emerging of a new pattern known as sidecar or proxy promoting to push all these common concerns outside of the business code and provides them on the edge by integrate a new layer to the underlying platform called Service Mesh. Istio is one of the leading Service Mesh implementing sidecar pattern. We will go during the presentation throw the core concepts behind Istio, the capabilities that provides to manage, secure and observe microservices and how it gives a new breath for both developers and operations. The presentation will be guided by a sequence of demo exposing Istio capabilities.

As more applications are being developed as a set of microservices, containers and platforms such as Kubernetes make many things much easier, but still leave untouched many operational issues such as traffic management and visibility, service authentication, security and policy. Istio, is a new service mesh that attempts to address many of these. We will discuss the architecture of Istio and the benefits it may offer to new microservice-based systems in a multicloud world.

Joe Onisick, Principal Engineer, Cisco discusses building the right network and understanding different overlay approaches at Cisco Connect Toronto 2015.

This document discusses Cisco SD-WAN and its ability to deliver intent-based networking to branches and the WAN. It begins by noting the business challenges of traditional network architectures in supporting modern needs around mobility, cloud applications, and security. It then introduces Cisco SD-WAN as a software-defined solution that provides automated, predictive, and business-intent driven networking through centralized control, application-aware policies, hybrid WAN transport, and integrated security and analytics capabilities. Key components of the Cisco SD-WAN architecture are also summarized, including the data, control, management, and orchestration planes.

SDN is an approach that decouples the control plane from the data plane in a network, allowing for centralized control and programmability. This document introduces SDN and network programmability, covering what SDN is and is not, the genesis of SDN, use cases solved by SDN, an overview of OpenFlow, Cisco's SDN solutions including ACI, network overlays, and network controllers. It also discusses the impact of SDN on IT service management.

Microservices have been great for accelerating the software innovation and delivery, but they also present new challenges, especially as abstractions and automated orchestration at every layer make pinpointing the issue seem like walking around a maze with a blindfold. Existing tools weren’t designed for distributed environments, and the new tools need to consider how to leverage these abstraction layers to better observe, test, and troubleshoot issues. Christian Posta walks you through Envoy Proxy and service mesh architecture for L7 data plane, the key features in Envoy that can help in debugging and troubleshooting, chaos engineering as a testing methodology for microservices, how to approach a testing and debugging framework for microservices, and new open source tools that address these areas. You’ll explore a workflow to discover and resolve microservices issues, including injecting experiments for stress testing the applications, gathering requests in flight, recording and replaying them, and debugging them step by step without affecting production traffic.

The document discusses Cisco's unified computing system (UCS) and how it provides a flexible, integrated intelligent infrastructure for data centers. It highlights key benefits of UCS such as simplified management, reduced costs, ability to evolve with business needs, and optimized performance for virtualization. UCS combines computing, networking, management, and storage access into a single integrated architecture to reduce complexity and improve agility.

The “internet of things” is the next revolutionary wave following profound changes brought to us by Personal Computers (connecting places) and Mobile Phones (connecting people on the go). This third wave heralds the beginning of the new era of pervasive connectivity, embedded intelligence, and application convergence. It will be the world where smart things will communicate among themselves and with us enabling greener, more efficient, and at the same time more comfortable environment. This talk will present a platform and products designed to serve the new markets enabled by the Internet of Things, with a particular focus on the value of the OSGi framework enabling convergence of Home Automation, Smart Energy, Electric Vehicle Charging, and e-health on a single remotely manageable platform. It will also provide insights on how the platform was developed leveraging the extensibility offered by the OSGi framework and ProSyst’s modular architecture. The built-in OSGi stack provides Java-level abstraction of the network interfaces and Smart Energy Profile 2.0 stack as well as cloud integration features such as web server, web services and standards-based remote management. The OSGi framework is the key enabler of the product lifecycle and remote application management mandatory for service provider driven deployments. The Smart Energy 2.0 standard is a key element of the future smart grid. And the work presented in this talk describes the first platform integrating the SEP 2.0 protocol stack with an OSGi based middleware. The OSGi based solution also provides higher level of device security through the use of secure element. The UDK-21 is build around a System-on-Chip STreamPlug (ST2100), the solution features a fully integrated HomePlug PHY/MAC and Analog Front End combined with the ARM926EJ-S processor and a rich set of interfaces. A demo showing Smart Energy Profile 2.0 use cases will outline these features. The demo will show how web based applications can interact with the OSGi stack on the already publicly available UDK-21 based gateway to control remote devices, such as a thermostat or an electric load. The access to SEP 2.0 devices will be done by the means of JSON-RPC based APIs, independent of the underlying device protocol, hence highlighting the benefits of a generic protocol agnostic architecture from the application standpoint. Other examples of the products that can be built around UDK-21 include Electric Vehicle Charger, Smart Meter, and a Basement Sensor Hub.

Sprekers: Stijn Van den Enden & Stijn Wijndaele (ACA IT-Solutions) DevOps is gericht op het tot stand brengen van een cultuur binnen organisaties waardoor het ontwikkelen, valideren en releasen van software sneller, meer betrouwbaar en frequenter kan verlopen. Om dit te realiseren staan het automatiseren van het 'software delivery process' en de bijhorende infrastructurele veranderingen centraal. Door de opkomst van 'Microservice Architecture' neemt het belang hiervan nog verder toe. In deze avondconferentie werd, na een korte toelichting over DevOps, nagegaan wat Docker en de Cloud kunnen betekenen voor uw business, en hoe zij als enablers kunnen dienen voor het tot stand brengen van een DevOps-cultuur. Het container-landschap waarvan tools zoals Kubernetes, Docker Swarm, ...een belangrijk onderdeel vormen, wordt toegelicht en er wordt ingegaan op de wijze waarop deze tools aangewend kunnen worden om 'development' en 'operations' efficiënt te laten samenwerken.
