Something stuck with me in a recent discussion with a customer about our data center and cloud solutions. Whilst focusing on future expectations, someone jokingly said that he could see the occasional cloud on the horizon but it didn't seem as completely overcast as everyone was forecasting. This got a laugh but also caught my attention because this was not the first time I had heard uncertainty about what the cloud will eventually become and on what timetable. I don't have a crystal ball, but there are some challenges that we can identify now. The trick, however, is to make sure our solutions to these challenges are flexible enough to help organizations prepare for and/or migrate to the cloud. One of the areas that I’d like to focus on is the problem of securing the cloud. How do we secure an elastic, shared resource where all interaction modes are allowed: client device to client device, client device to computing utility, computing utility to computing utility?

Cloud computing promises increased efficiency for service providers and enterprise IT, and greater agility for users. To realize those promises, the cloud needs to be made up of large, shared pools of standardized and virtualized resources (including server, storage, and network elements). The larger the resource pool, the greater the efficiency, so scalability is key. But there is a problem. Most networks today currently don’t scale well. Read more...
Late last year, I had the opportunity to participate in an executive roundtable with Phil Sayer of Forrester Research and Andy Bach of New York Stock Exchange (NYSE) Euronext. The conversation included an interesting mix of industry-wide observations from Phil on cloud computing, a description of Juniper’s vision for building cloud-ready data center networks from me, and Andy’s experience of designing and building the next generation exchange network.
Phil outlined how cloud computing and server virtualization will drive the future of data center networking. My takeaway was that regardless of company plans for public cloud services, evolving their data centers into a private cloud will deliver significant business benefits like greater agility and lower costs.
Andy spoke about the industry-wide mandate to reduce or even eliminate network latency – which represents a shift from the previous focus on primarily network availability. NYSE Euronext has nearly 3,500 listed companies with a market capitalization of more than $12 trillion. Today, a trade transacts in microseconds, and there may be hundreds of quotes per trade. In 2005, the value of the trades transacted exceeded the market capitalization of the listed companies; this meant a big increase in the turnover rate of shares. In 2008, the value of trades transacted nearly tripled the market capitalization. This turnover increase is driving over 120 trades per millisecond! Obviously, the exchange has a critical need to protect itself from malicious attacks and to record and store all transactions for seven years to comply with federal and international regulations.
One logical question is “What do my business and technical needs have in common with NYSE Euronext, and how are they related to cloud computing?” The answer is “a lot,” in terms of network availability, latency, performance and compliance.
At Juniper, we offer a pragmatic process to make your data center network cloud-ready: simplify, share and secure. Our simplification strategy flattens the network to remove latency, improve server-to-server performance and lower costs. Our process of sharing extends Layer 2 domains between global data centers to enable mobility with live migration, improving disaster recovery and application availability. And our security process evolves policy enforcement from traditional physical separation to identity- and application-based enforcement, with a single tool for administering policy and monitoring compliance.
Anyone who says “If it’s good enough for NYSE Euronext, then it must be good enough for me” is more right than they know. The high-availability, low-latency and compliance benefits NYSE Euronext will achieve with a simplified two-layer data center network design can help you build a cloud-ready data center network too.
Below are some videos of the event. Let me know your thoughts by leaving a comment and I’ll be sure to get back to you.
VIDEO ONE: Introduction
Phil Sayer presents his view of the current marketplace and how the recession is affecting budgets and staff. Andy Bach considers the ever increasing pressure on IT to deliver results, even in the face of decreasing budgets and staff. I lay out how Juniper is helping customers address these financial challenges with high-performance networks.
VIDEO TWO: Virtualization
Phil explains why he thinks that Virtualization is now. Andy Bach explains NYSE’s adoption of virtualization in the context of the real-time data environment and how virtualization has helped NYSE Automate back office processes I discuss the new requirements virtualization has placed on the Data Centre and how it is changing the fundamental design and architecture.
VIDEO THREE: Ethernet
Is Ethernet the future for storage? Phil says yes, because it simplifies the switching architecture and reduces cost but, he explains how legacy Fiber Channel Storage Networks will be around for a while longer. I explain how Convergence Enhanced Ethernet and Fiber Channel over Ethernet standards are helping the deliver Ethernet Storage Networks and I introduce iSCSI. Andy Bach discusses the cost advantages of delivering a unified fabric within the data center using 10gE.
VIDEO FOUR: The Cloud and Data Centre Architecture
Phil sets out the landscape for Cloud Networking and discusses how developments such as Infrastructure as a Service (IaaS) and Dynamic and Shared Services is impacting the Architecture and the Security of the Data Centre. Andy explains how Internal Cloud Computing is reducing time-to-market in Financial Services. I talk about the adoption of the Cloud within both Service-Providers and Enterprises.
VIDEO FIVE: Business Best Practices and Dual Vendor Strategy
Is a dual vendor strategy a good initiative? Phil outlines the case; based on competitiveness and innovation. Andy Bach discusses the NYSE approach to the second vendor strategy to ensure their network diversity and innovation. I discuss how Juniper can mitigate the risk for an organization adopting a dual vendor strategy by ensuring Interoperability between vendors.
