2 For longer than the enterprise has been talking about them, service providers have been implementing them. [sent-11, score-0.798]

3 They’ve got their own set of standards and reference architectures and even language to describe them, but in a nutshell that’s what a service provider does: offers services. [sent-12, score-0.826]

4 All of it generates traffic and all of must pass through a service provider’s network – and be accounted for. [sent-20, score-0.665]

5 And while the latest viral video is chewing up bandwidth on the provider’s network, the provider must maintain its network such that call quality is above par or suffer the consequences. [sent-21, score-0.878]

6 Oh, and don’t forget that the provider has to authorize and monitor use of those services because metering is often handled based on bandwidth usage. [sent-22, score-0.71]

7 Complicating the service provider’s environment is the fact that while just about all its traffic today may be IP-based at the network layer, at the transport and application layers many of the protocols become more complex. [sent-23, score-0.735]

8 It’s not just about the data flowing over the service providers’ wires, it’s about the users and the services they use; about hooking up the right user with the right service level agreement with the right service using the appropriate policies and metering systems. [sent-26, score-1.21]

9 THE SERVICE DELIVERY NETWORK It isn’t enough that solutions for the service provider are able to meet the stringent requirements of such a demanding environment. [sent-28, score-1.003]

10 Solutions for service providers must support the fast-paced scaling requirements that go along with rising traffic demands from users. [sent-29, score-1.244]

11 Solutions for service providers must be adaptable, able to support the varying protocols and services offered by a service provider with an eye toward future services that may be offered. [sent-30, score-2.175]

12 An SDN comprises a set of services specifically geared toward meeting the demands of the service provider and supporting their somewhat unique set of protocols and applications. [sent-33, score-1.347]

13 While both enterprises and service providers are in need of IPv6 support, service providers are in need of large (very large) scale support. [sent-34, score-1.591]

14 Both service providers and enterprises require intelligent, scalable DNS , but where the enterprise requires the ability to support hundreds of queries a second the service provider must support thousands to millions of queries per second. [sent-35, score-1.899]

15 A SDN is a NEBS-compliant system of components that provides a variety of services specifically for service providers, enabling them to meet the traffic and processing demands unique to the service provider network. [sent-37, score-1.664]

16 A SDN also, like an ADN, affords service providers the control they need over traffic. [sent-38, score-0.799]

17 One of the biggest issues for service providers today is “big data”; which only grows up and out, never down and in. [sent-39, score-0.825]

18 An SDN provides that point of control for the service provider, reducing the complexity associated with managing multiple types and high volumes of traffic while reducing the overall operating costs associated with rising data and service usage. [sent-42, score-1.106]

19 An SDN does for service providers what an ADN does for the enterprise. [sent-43, score-0.748]

20 But it does it faster and at higher volumes and over the broader set of protocols and services required to support a service provider network. [sent-44, score-1.176]

Introduction: Cloud-based services for all things digital will either drive – or die by – bandwidth Consumers, by definition, consume. In the realm of the Internet, they consume far more than they produce. Or so it’s been in the past. Broadband connectivity across all providers have long offered asymmetric network feeds because it mirrored reality: an HTTP request is significantly smaller than its corresponding response, and in general web-based activity is heavily biased toward fat download and thin upload speeds. The term “broadband” is really a misnomer, as it focuses only on the download speed and ignores the very narrowband of a typical consumer’s upload speed. cloud computing , or to be more accurate, cloud-hosted services aimed at consumers may very well change the status quo by necessity. As providers continue to push the notion of storing all things digital “in the cloud”, network providers must consider the impact on them – and the satisfaction of their customer base with performa

Introduction: Can you really create an infinitely scalable infrastructure for less than $100 using Amazon's storage, grid, and queuing services platform? It appears so, at least for the right application. Amazon beams a spot light on the future battle of the roll-your-own versus the connect-the-dots approach to building next generation websites using core external services. Their argument is strong. Using Amazon's platform you can quickly build an infrastructure that would otherwise take an eternity to make, a pile of money to create, and an unbounded mass of people to implement and maintain. Yet Amazon doesn't provide SLAs, so you can you really trust them with your crown jewels? Facebook recently leap frogged Amazon's vision with an even more comprehensive set of services. The battle for the future is on. Site: http://aws.amazon.com/ Information Sources Slides: Building Highly Scalable Web Applications Podcast: Technometria: Amazon Web Services Amazon Services Home .

Introduction: This is a guest post by Frédéric Faure (architect at Ysance ) on the differences between using a cloud infrastructure and building your own. Frédéric was kind enough to translate the original French version of this article into English. I’ve been noticing many questions about the differences inherent in choosing between a Cloud infrastructure such as AWS (Amazon Web Services) and a traditional physical infrastructure. Firstly, there are a certain number of preconceived notions on this subject that I will attempt to decode for you. Then, it must be understood that each infrastructure has its advantages and disadvantages: a Cloud-type infrastructure does not necessarily fulfill your requirements in every case, however, it can satisfy some of them by optimizing or facilitating the features offered by a traditional physical infrastructure. I will therefore demonstrate the differences between the two that I have noticed, in order to help you make up your own mind. The Fram

3 0.72017175 1184 high scalability-2012-01-31-Performance in the Cloud: Business Jitter is Bad

Introduction: One of the benefits of web applications is that they are generally transported via TCP, which is a connection-oriented protocol designed to assure delivery. TCP has a variety of native mechanisms through which delivery issues can be addressed – from window sizes to selective acks to idle time specification to ramp up parameters. All these technical knobs and buttons serve as a way for operators and administrators to tweak the protocol, often at run time, to ensure the exchange of requests and responses upon which web applications rely. This is unlike UDP, which is more of a “fire and forget” protocol in which the server doesn’t really care if you receive the data or not. Now, voice and streaming video and audio over the web has always leveraged UDP and thus it has always been highly sensitive to jitter. Jitter is, without getting into layer one (physical) jargon, an undesirable delay in the otherwise consistent delivery of packets. It causes the delay of and sometimes

1 0.93622154 1450 high scalability-2013-05-01-Myth: Eric Brewer on Why Banks are BASE Not ACID - Availability Is Revenue

Introduction: In NoSQL: Past, Present, Future Eric Brewer has a particularly fine section on explaining the often hard to understand ideas of BASE (Basically Available, Soft State, Eventually Consistent), ACID (Atomicity, Consistency, Isolation, Durability), CAP (Consistency Availability, Partition Tolerance), in terms of a pernicious long standing myth about the sanctity of consistency in banking. Myth : Money is important, so banks must use transactions to keep money safe and consistent, right? Reality : Banking transactions are inconsistent, particularly for ATMs. ATMs are designed to have a normal case behaviour and a partition mode behaviour. In partition mode Availability is chosen over Consistency. Why? 1) Availability correlates with revenue and consistency generally does not. 2) Historically there was never an idea of perfect communication so everything was partitioned. Your ATM transaction must go through so Availability is more important than

Introduction: A lot of apps need to map IP addresses to locations. Jeremy Cole in On efficiently geo-referencing IPs with MaxMind GeoIP and MySQL GIS succinctly explains the many uses for such a feature: Geo-referencing IPs is, in a nutshell, converting an IP address, perhaps from an incoming web visitor, a log file, a data file, or some other place, into the name of some entity owning that IP address. There are a lot of reasons you may want to geo-reference IP addresses to country, city, etc., such as in simple ad targeting systems, geographic load balancing, web analytics, and many more applications. This is difficult to do efficiently, at least it gives me a bit of brain freeze. In the same post Jeremy nicely explains where to get the geo-rereferncing data, how to load data, and the performance of different approaches for IP address searching. It's a great practical introduction to the subject.
