Scaling the cloud

•

0 gefällt mir•578 views

Some people use the cloud. Others build one. This talk will be about building your own enteprise cloud. When running a cloud 3 things are important: scaling, easy (cost effective) maintenance, and stability. These 3 points are very closely related through one subject: automation. Thanks to the easy automation tools like pxe boot (for booting a new setup) and puppet (for configuring a new system) setting up a new server was never this easy. But how can we use these tools to create a scalable infrastructure that is cost effective, stable and easy to maintain? In this talk you will learn about how to design a scalable secure architecture and how to make the right tools work for you without going into to much detail.

Case Study - IPv6 Challenges for Cloud Service Providers

Manuel Schweizer

There is a growing trend today of enterprises leveraging both Amazon Web Services (AWS) and on-premise OpenStack-based private clouds. However, the default networking option in OpenStack remains broken and the plethora of confusing plug-ins makes networking in OpenStack mysterious and difficult to manage. Enter MidoNet, the open source network virtualization solution from Midokura favored by DevOps cultures in web scale enterprises and service providers around the world. This session will present case studies from several end user deployments, showing how they use MidoNet to build, run and manage large-scale virtual networks in OpenStack clouds. The session will also discuss how transitioning from a public to private cloud enables organizations to accomplish much more with the same resources, without over-simplifying the inherent complexity of running an OpenStack cloud.

Presented on November 29th, 2014 at TechEd Europe 2014 in Barcelona: The rise of virtualization and new applications has created pressure on IT departments to develop, deliver, and maintain an application and storage infrastructure that is not only high performing, but also simple to manage, VM-centric, and highly scalable. In this Lunch Presentation, we discuss how to create the ideal infrastructure for Hyper-V and virtualized Windows applications, that is always available and literally invisible to the application teams. We also explore a real-world Azure Pack deployment of a European service provider Synergics during this technical presentation. One of the Synergics’ architects explains and demonstrates how they deployed a scalable, easy-to-manage cloud based on Azure Pack.

With the growing popularity of Container technology comes the growth of container-based attacks – but understanding your security needs will keep you ahead of the game. Container adoption is skyrocketing, growing 40% in the last year. And it makes sense – the agility, operational efficiencies and cost savings of containerized environments are huge benefits. But as more organizations rush to leverage containers, security is increasingly becoming a major concern and is the top roadblock to container deployment. What do you need to know (and do) to keep your container environments safe?

As kubernetes matures into the standard de facto Operating System of the Cloud, in addition to a shift in deployment methods such as GitOps and Continuous delivery paradigms - automation of security is one of our main concerns The security policy alignment starts from the CI/CD pipelines, and continues to runtime security solutions. In this talk, we will introduce a few solutions built around kubernetes from the early stages of the CI/CD pipelines through runtime application security models which we are seeing from many companies on the security vertical. Scanning tools [ static ] Runtime [ pro-active, permissive ] Few words about Haggai: Haggai is a DevOps Architect, Group & TechLead at Tikal, for the past 15 years Haggai’s has provided solutions in the domains of Ci/CD, Configuration Management, and Security. And in the past, ~4 years specialized in Kubernetes-based deployment schemes.

Not since the rise of Service Oriented Architecture (and the supporting Fusion Middleware technology) over a decade ago have we seen so much rapid change in terms of application and infrastructure architecture. Cloud, Microservices and DevOps are perhaps the most explicit examples – but many other developments in technology, architecture and even the industry at large have an impact on how enterprises consider and employ IT – such as machine learning, IoT, blockchain. In this session for (infrastructure, solution, application, enterprise, security, data) architects – we will present the main stories, roadmaps and technologies from Oracle OpenWorld 2017 (and JavaOne) that influence, shape and enable architecture. We will brainstorm together on the consequences of the new directions outlined by Oracle – and coming our way from other quarters. We are seeing a a lot of change. New opportunities arise – that may become challenges or threats if we fail to recognize and embrace the change in time. This session will help us all to get a better handle on the winds in enterprise IT in general and in Oracle land in particular. Among the topics we will present and discuss are: - The Only Way is Up – the inevitable and imminent move from on premises to the cloud, and upwards in the stack – from IaaS to SaaS - Security and Ops in a hybrid landscape (multiple clouds & on premises, multiple technologies & interaction channels) - Autonomous Database – what, when, how - Oracle’s cloud strategy, High PaaS and Low PaaS, Open [source] technology (star of the show: Apache Kafka) and the commodization of the traditional Oracle platform - Container and Cloud Native at Oracle Cloud (Docker, Kubernetes Container Platform, Wercker, Istio Service Mesh, CNCF) - Serverless - Java Reborn – for microservices and cloud, modularized (highlights from the JavaOne conference) - Disruptive: Blockchain, IoT, Machine Learning

A successful social game can achieve very rapid growth to large scale during a short period of time, with extreme cases (CityVille, The Sims Social, Gardens of Time) achieving millions of daily active users and tens of millions of monthly active users within a few weeks of launch. In this presentation I will argue that achieving the fastest possible sustainable speed of development is the most important technical factor in launching and operating a successful social game, or indeed any large-scale web business -- whether at startup phase, during rapid growth, or established and mature. I will propose some techniques, both technical and non-technical, to optimize rapid development at large scale. Finally, I will describe some of the typical architecture, processes, and tools used in the development of both the transactional and analytical systems of social games.

You know that adopting Continuous Delivery and DevOps is key to a high-performance company. You’ve read the books and are ready to build microservices in the cloud. Great! Let’s go back to the principles and see how to apply them in a cloud native environment. What used to about shipping code to static servers, is now about quickly creating decoupled pipelines for new services that are readily wired up into the platform and everything is driven by code. This talk will give concrete guidance in a world where autonomous teams continuously deploy many independent services and containers into an infrastructure that is dynamically created via APIs. Learn how to establish a culture that fosters fast local decisions and is driven by fast feedback. Remove friction by removing the staging environment and still release with confidence. Listen to stories from the trenches on true DevOps on AWS with “You build it, you run it” teams from AutoScout24, the largest online car marketplace Europe-wide. https://devopsconference.de/continuous-delivery/cloud-native-continuous-delivery/

With more memory available, system performance of three Dell devices increased, which can translate to a better user experience Conclusion When your system has plenty of RAM to meet your needs, you can efficiently access the applications and data you need to finish projects and to-do lists without sacrificing time and focus. Our test results show that with more memory available, three Dell PCs delivered better performance and took less time to complete the Procyon Office Productivity benchmark. These advantages translate to users being able to complete workflows more quickly and multitask more easily. Whether you need the mobility of the Latitude 5440, the creative capabilities of the Precision 3470, or the high performance of the OptiPlex Tower Plus 7010, configuring your system with more RAM can help keep processes running smoothly, enabling you to do more without compromising performance.

Created by Mozilla Research in 2012 and now part of Linux Foundation Europe, the Servo project is an experimental rendering engine written in Rust. It combines memory safety and concurrency to create an independent, modular, and embeddable rendering engine that adheres to web standards. Stewardship of Servo moved from Mozilla Research to the Linux Foundation in 2020, where its mission remains unchanged. After some slow years, in 2023 there has been renewed activity on the project, with a roadmap now focused on improving the engine’s CSS 2 conformance, exploring Android support, and making Servo a practical embeddable rendering engine. In this presentation, Rakhi Sharma reviews the status of the project, our recent developments in 2023, our collaboration with Tauri to make Servo an easy-to-use embeddable rendering engine, and our plans for the future to make Servo an alternative web rendering engine for the embedded devices industry.
