With Amazon Virtual Private Cloud (Amazon VPC) you can build your own virtual data center networks in seconds. Every VPC is free, but it comes with enterprise-grade capabilities that would cost millions of dollars in a traditional data center. How is this possible? Come hear how Amazon VPC works under the hood. We uncover how we use Amazon-designed hardware to deliver high-assurance security and ultra-fast performance that makes the speed of light feel slow. Leave with insights and tips for how to optimize your own applications, and even whole organizations, to deliver faster than ever.

금융권 최신 AWS 도입 사례 총정리 – 신한 제주 은행, KB손해보험 사례를 중심으로 지성국 사업 개발 담당 이사, AWS 정을용 수석, 신한 DS 노용헌 이사, 메가존 금융권 클라우드 규제 환경에서도 많은 고객들이 AWS를 사용하여 업무를 혁신하여 왔습니다. 크게 보면 새로운 사업에 AWS를 활용하여 혁신할 수 있는지와 기존 업무를 AWS로 신속하게 안전하게 이전하는 것으로 누누어 볼 수 있습니다. 첫 번째 사례로 신한 제주 은행 지니앱 개발 사례를 통하여 신한 DS가 비금융 앱인 "제주 지니" 프로젝트에 AWS기반 데브옵스 체계를 금융권 최초로 구축한 사례를 소개합니다. 단순히, Infra form factor만 클라우드를 활용하던 관행에서 벗어나 개발, 테스트, 스테이징, 배포 등 CI/CD 전 과정을 AWS상에서 자동으로 구현하는 과정을 통하여 기존 On premise 대비 AWS 클라우드의 장점 및 이를 통해 배운 점 등을 공유합니다. 다음으로는 해외 북미 법인 DC 전체를 AWS 로 All-in 마이그레이션을 통하여 운영중인 K 손해보험 사례를 공유합니다. K 손해보험의 미주법인은 새롭게 시행된 미국의 강력한 사이버 보안 정책이 23 NYCRR500을 준수하면서 On premise 환경보다 우월한 보안 요건을 준수하기 위하여 AWS 클라우드 검토하게 되었으며 AWS의 금융전문파트너인 메가존과 함께 뉴저지와 캘리포니아에 위치한 2개의 데이터센터를 모두 AWS 클라우드로 이관하는데 성공하였습니다. 약 6개월간 진행된 해당 프로젝트에 대한 사례소개 및 이를 통한 비용 절감의 효과를 공유해 드리며 현재도 계속 지원하고 있는 메가존의 AWS 클라우드 매니지드 서비스의 효과도 함께 전달 드립니다.

In MicroMarketMonitor’s recent report, it was noted that the North American content delivery network market is expected to grow from $1.95 billion in 2013 to $7.83 billion in 2019. One significant factor driving this growth is end user interaction with online content. The interaction between a user and online content is far more complex today than it was a few years ago. Today’s users are much more likely to be streaming a longer video from a mobile phone or accessing a SaaS portal when working from home. These are far more complex experiences that did not exist five or so years ago. Given the expected growth of the CDN market in the coming years, this post will define exactly what a CDN is and how it operates. A content delivery network, also called a CDN, improves the performance, security and reliability of a website. Since the start of the internet, websites have evolved in how they deliver content to the end user. In the example below, you will see the CDNetworks’ Twitter stream. Highlighted in red, is what is known as static content. The CDNetworks logo and profile descriptions are basic graphics and HTML text that rarely change. Highlighted in yellow, is what is known as dynamic content. The Twitter stream represents content that is always changing and moving.

In MicroMarketMonitor’s recent report, it was noted that the North American content delivery network market is expected to grow from $1.95 billion in 2013 to $7.83 billion in 2019. One significant factor driving this growth is end user interaction with online content. The interaction between a user and online content is far more complex today than it was a few years ago. Today’s users are much more likely to be streaming a longer video from a mobile phone or accessing a SaaS portal when working from home. These are far more complex experiences that did not exist five or so years ago. Given the expected growth of the CDN market in the coming years, this post will define exactly what a CDN is and how it operates. A content delivery network, also called a CDN, improves the performance, security and reliability of a website. Since the start of the internet, websites have evolved in how they deliver content to the end user. In the example below, you will see the CDNetworks’ Twitter stream. Highlighted in red, is what is known as static content. The CDNetworks logo and profile descriptions are basic graphics and HTML text that rarely change. Highlighted in yellow, is what is known as dynamic content. The Twitter stream represents content that is always changing and moving.

Content Delivery Networks are on the front lines of application performance. ThousandEyes provides deep insights into CDN performance, including geographic load balancing, latency and availability. We'll help you detect and diagnose issues with your CDN providers and track down problems at the origin or the edge. In these slides, we'll share how to: 1. Measure and baseline CDN performance. 2. Diagnose issues with specific files, caches or edge locations. 3. Share data with your CDN to resolve problems.

As digital consumption of rich media content explodes and with audience expectations at its peak, media providers have been challenged with not only delivering high-quality audience experiences but also the audience analytics in realtime to enable actionable insights for content publishers. Arkena, one of Europe’s leading media services organizations chose to power it’s analytical platform with Hortonworks Data Platform to cost effectively store and analyze over 3.5 terabytes of data per day. Join Hortonworks and Arkena as they share the industry challenges faced, the solution created which enables real-time and better analytics for their customers.

Integrating content delivery networks into your application infrastructure can offer many benefits, including major performance improvements for your applications. So understanding how CDNs perform — especially for your specific use cases — is vital. However, testing for measurement is complicated and nuanced, and results in metric overload and confusion. It's becoming increasingly important to understand measurement techniques, what they're telling you, and how to apply them to your actual content. In this session, we'll examine the challenges around measuring CDN performance and focus on the different methods for measurement. We'll discuss what to measure, important metrics to focus on, and different ways that numbers may mislead you. More specifically, we'll cover: Different techniques for measuring CDN performance Differentiating between network footprint and object delivery performance Choosing the right content to test Core metrics to focus on and how each impacts real traffic Understanding cache hit ratio, why it can be misleading, and how to measure for it

Caching has been an essential strategy for greater performance in computing since the beginning of the field. Nearly all applications have data access patterns that make caching an attractive technique, but caching also has hidden trade-offs related to concurrency, memory usage, and latency. As we build larger distributed systems, caching continues to be a critical technique for building scalable, high-throughput, low-latency applications. Large systems tend to magnify the caching trade-offs and have created new approaches to distributed caching. There are unique challenges in testing systems like these as well. Ehcache and Terracotta provide a unique way to start with simple caching for a small system and grow that system over time with a consistent API while maintaining low-latency, high-throughput caching.

本报告先简要介绍淘宝网的业务和背后网站系统的主要组成部分,描述所使用的主要软件和当前的系统规模,以及未来的技术挑战,当前的淘宝网站系统是完全采用开源软件和自主开发。 接着,叙述淘宝系统的主要发展过程,在系统规模较小时主要采用商用软件,随着规模越来越大商用软件逐步无法满足需求,不得不采用开源软件结合自主开发,一方面通过使用开源软件提高系统开发的效率,另一方面通过自主开发可以按需求在架构上取舍将系统性能做到极致,这里会举三个例子说明,一是淘宝如何逐步建设世界上最大的面向图片的CDN系统,采用高性价比的混合存储系统,目前有1000Gbps流量的承载能力,今年会发展到约2400Gbps,二是根据网页使用图片的特定抛弃目录空间实现了高可扩展的对象存储系统TFS,目前部署了6PB多的存储空间,存放了4PB多的图片,今年会建设到12PB的存储空间,三是将淘宝的核心数据库从基于IBM小型机、Oracle商用数据库和EMC高端存储的解决方案迁移基于PC服务器加MySQL数据库,结合高速非易失的PCI-E存储设备和多层次的系统优化,实现近百倍的性能提升,非常轻松地应付双11和双12的大促活动。这个过程可以总结出商用软件不能满足大规模系统的需求,采用开源软件与自主开发相结合,有更好的可控性,更高的可扩展性,规模效应使得研发投入都有更高的产出。 然后,描述淘宝的开源策略,淘宝系统中使用大量的开源软件,并在开源软件的基础上进行改进和定制,并把工作成果回馈给上流的开源社区,例如淘宝维护了自己的Linux内核树并不断地向Linux社区贡献patch,目前淘宝在对Linux内核贡献补丁数的公司排名为115,开源了基于Nginx的Tengine服务器,以及向Oracle回馈了JVM的补丁和MySQL的补丁,向Apache回馈hadoop和hbase的补丁等等。淘宝建设了淘蝌蚪开源平台,并开源多年开发主力的基础软件,如分布式存储系统TFS、分布式缓存和K/V系统TAIR、海量数据库OceanBase、分布式数据库中间件 TDDL、手机自动化测试框架Athrun等等。淘宝针对数据密集型应用的特点定制了低功耗服务器,先应用在CDN系统中,淘宝创建了greencompute.org网站,并开源了低功耗服务器的硬件规格和应用测试数据,阿里云开源了直流服务器,和业界一起推进绿色计算。 淘宝是开源系统的受益者,并积极参与开源生态系统的建设,促进开源生态系统的发展,积累更好的口碑,凝聚人才,迎接未来更大的技术挑战。
