2. Executive Summary Business Imperative Data Centre Platform
Today’s business environment is faster paced and more competitive than ever before.
With almost ubiquitous broadband availability more and more B2C and B2B transactions are taking place online as the default engagement model. Customers expect 24 hour always on access and instant gratification.
The Internet and automation have been embraced by a new wave of businesses to disrupt traditional physical operations through new business models. Amazon disrupted high street bookstores and then extended into almost every retail segment leveraging automation to reduce costs and offer a one stop shop. Netflix has almost killed the DVD rental business. Airbnb and Uber have aggregated and automated the hospitality and transportation business.
Social networks have aggregated potential customers offering businesses a new customer engagement model and another virtual channel to market.
The Internet offers businesses the opportunity to take a new product or service from concept to delivery in the same day.
Failure to comply with this new paradigm is almost certainly a recipe for business failure.
Data Centre Platform
The Data Centre is the heart and brain of a business in a digitised world. The services resident in the Data Centre must keep pace with changes in the business that it supports.
The Data Centre is the heart and brain of the digitised business anatomy then the Data Centre network is the circulatory system. In order to satisfy customer demands and expectations the Data Centre network must be highly reliable, fast and low latency.
The network must support sharing and distribution of workload allocation across compute and storage resources as required by short term and long term ebb and flow of business transactions.
The Data Centre network must also be capable of seamless expansion, extension and reconfiguration, in real time, to enable business to develop and evolve.
Network Solution
On order to meet the demands of the modern digitised business the supporting Data Centre the network platform architecture must be simple, open and smart. High capacity switching calls for highly scalable federations of many switches that do not require rip and replace once an individual device reaches full capacity.
The architecture must be open to enable deployment of devices sourced from multiple vendors to leverage best of breed and avoid vendor lock in and potential dead ends.
The network should be defined logically in software rather than many physical devices all of which must be individually configure and managed. Rather the physical switching fabric should be represented as an abstraction of it’s collective functionality and managed as a single virtual entity.
In addition to switching the network must also homogeneously integrate routing and security functions within the overall abstraction.
Juniper Networks offers a comprehensive set of high performance switching, routing and security products offering open API in support of a virtualised SDN.

4. Data Centre Imperatives
Data Centre infrastructure must be agile to instantly and seamlessly adapt to business and operational changes.
The Data Centre network must instantly and seamlessly change to meet both planned business events, over which the enterprise has control, and unplanned operational events over which the enterprise has no control.
Planned events include changes and additions to internal day to day and week to week applications such as CRM, ERP, HR, payroll, finance applications and social network presence. Other planned events may include web based sales campaigns, training webinars, online surveys, new product launches and price list changes etc.
Planned events are relatively easy to manage as these are under enterprise control.
However unplanned operational events can be more complex and potentially damaging. The enterprise must be able to absorb both internal and external systems failures and associated implications. Events such as server or internal network failures must be seamlessly overcome by reassignment of resources or alternative traffic routings. Malicious attacks such as DDoS attacks must be mitigated. Externalities such as severe weather or public transport network disruption may have implications for the Data Centre such as a temporary need to turn up additional resources to support an increased number of remote workers.
Whether manually instigated, to support planned business events, or automatic policy driven, to mitigate unplanned operational events, the Data Centre network infrastructure must rapidly flex to maintain business continuity.
In large scale environments comprising many servers, switches, routers and firewalls etc changes must be executable without the requirement for detailed operator understanding of individual devices. The operator must be able to manage infrastructure based upon an abstract knowledge that enables the environment to be seen as singleton, very large compute, storage, switching, routing and security objects.

5. Data Centre Evolution
Legacy Hierarchical Data Centre Network Architecture
Compute and storage resources are in silos
Network services are on physical appliances
High latency blocking network
Tasks are not automated
Orchestration is decentralised
Security is an afterthought
Leaf Spine Data Centre Network Architecture
Compute and storage resources are pooled
Network services are virtualised and distributed
Low latency high capacity non blocking network fabric
Adds, moves and changes are fully automated
Orchestration is fully centralised
Security is integrated
In pursuit of the goals previously discussed Data Centre architectures are changing from dedicated compute, storage and networking resource silos to pooled resource environments. Many resources are increasingly virtualised enabling many functions to execute on simplified utility hardware and software. Functions can be run on any available resource and are not constrained to execution on specific platforms thus reducing queuing and cost. Network simplification reduces latency and eliminates blocking to accelerate execution. The internal network is transforming from a multi tiered hierarchical architecture to a flatter leaf and spine topology where resources can interact as peers at high speed and low latency.
Whilst hardware is always required to execute any given function centralised software orchestration rationalises and organises resources to ensure maximum operational efficiency and control costs.
This is a software driven and defined network evolution. This evolution is best achieved in an open environment without proprietary lock in. Proprietary lock in not only exposes the enterprise to security of supply risk but also to feature and functionality dead ends or delays and higher costs. Open systems assure access to latest innovation and best of breed technology.
Software orchestrated rationalisation and reorganisation of resources to reduce complexity and cost.

6. Walking In The Footsteps Of Giants
Leverage industry best practice to reduce costs, maximise performance and protect investment
The very largest Data Centre practitioners have led the Data Centre evolution. Faced with massive volumes and growth in user traffic and consequential cost increase both Facebook and Google have re-architected their Data Centres. Both companies have published details of their Data Centre architecture and philosophy and the underlying logic. Whilst there are subtle differences in the detailed approaches taken by Facebook and Google there are important common themes.
Both companies have deployed flattened leaf and spine topology Data Centre networks capable of massive scaling. These networks separate forwarding and control planes simplify operation and maximise performance.
Both companies have deployed SDN to centralise, automate and simplify control using open standards protocols. This approach leverages, and enable reuse of, the work of the broader development community and preserves vendor independence thus keeping all future development directions open.
Whilst most enterprises are not yet at the scale of companies such as Facebook, Google, Linkedin and Twitter these companies are leading and defining best practice from which enterprise architects can learn and avoid making costly missed steps.
In their Magic Quadrant for Data Centre Networking published May 2015 Gartner notes:
“The influence and lessons from hyperscale cloud deployments (such as Facebook, Google and Amazon) have had major repercussions in the enterprise Data Centre networking market, where much smaller networks can benefit from this experience.”

The modern Data Centre network needs to enhance your ability to respond quickly. It needs to be ready for Instant Evolution. And to do that, there are three requirements:
A simple network means fewer devices and fewer layers, all of which can be managed as one. Traffic flows faster because it goes through fewer boxes that slow it down. And by managing dozens of devices as one single unit, it makes configuring and modifying the network much easier, for example if you want automate routine tasks.
Now what about an Open Network? At the data level the industry has been open for many years now: almost all traffic these days runs on IP – the Internet Protocol. But when it comes to controlling the network, there are very different definitions of “open”. For Juniper, it means adhering to industry standards such as Open Stack. It means publishing APIs that allow our partners and customers to talk directly to the operating system and define the network in the manner that best suits their needs. It means you can easily add hardware from other vendors, whether networking, storage, servers, test equipment, or anything. And you can use your own methodologies and tools. You can incorporate the network into your management tools for moving workloads, jobs or applications between virtual machines, between data centers, or between clouds. If you build your network on open standards YOU have choices and YOU are in control.
And finally, a smart network is one that is able to react to your needs rapidly and accurately. It can talk to applications, management or orchestration tools, and servers to automatically react to their needs and reconfigure itself. And do so far more rapidly and accurately than any human operator could. It lets you automate many tasks, including the task of checking that the changes it is about to make are correct and valid. It is smart enough to present your staff with simple ways of managing it, no matter how complicated the underlying complexity may be.

9. MetaFabric: all of the networking components brought together in a single solution
INTEGRATED
MANAGEMENT
SECURITY
DIRECTOR
Apache Thrift
B/OSS, ITSMs, DevOps, Platforms & Apps
The Juniper Networks solution that underpins all of these cases is a Simple, Open and Smart Data Centre networking architecture called MetaFabric.
MetaFabric is an architecture for building a coherent network within and between data centers. Coherent means a network that acts as a single system rather than a collection of devices. The trends in cloud computing are clear: most organizations will soon be transacting in an environment of hybrid clouds. MetaFabric provides the flexibility customers require to transition from today’s data centers to tomorrow’s Cloud data centers. It is delivered through a combination of scalable switching, routing, and security platforms leveraging programmable systems and open APIs, as well as adaptable software that delivers advanced services, orchestration and SDN solutions.
MetaFabric includes our switching, routing and security portfolio. But more importantly also integrates the SDN overlay, typically from Juniper or VMWare. Because we are open it is also possible to integrate virtual function not only from Juniper, but also from third parties such as sandvine, Akamai, sonus, F5, etc…. Finally Metafabric also includes the management and automation tools that are required in the modern Data Centre
A lot of our customers appreciate the flexibility Juniper provides for this scenario. To use the words of one of our customers: “Our technical people love Juniper because there is always a solution“.

10. How is Juniper different?
We are truly open
We offer a full networking stack
Everybody in the networking industry talks about being open. It’s an ill defined term, but at Juniper we truly believe that we are as open as possible. Our products are built upon open standards wherever possible, without proprietary protocols. Take our SDN solution as an example. It’s not tied to our hardware, or even specific versions of hardware like some other vendors. When you dig a little deeper in to our SDN controller, Contrail, you’ll even see that it is built upon the MPLS and BGP – the foundations of modern networks
If we look back in time you’ll that Juniper was open before it was the latest buzzword. We’ve had a Junos SDK since 2009 which provided open APIs in t our products that would allow them to be controlled by third party applications. Juniper were doing SDN before SDN was even invented
Our contrail controller is also open source. This means that anyone can download it and look at the source cod. If there’s features missing that they need they can then develop them, and contribute it back to the community. That’s truly open
There’s many vendors of networking equipment. But few are able to offer a full networking stack. Juniper have a full suite of switching, routing and security products for the Data Centre. We have the right product for the smallest Data Centre that fits within a single rack, right up to the massively scalable Data Centres that power the cloud economy
Finally, we are embracing virtualisation of the network. Juniper have virtualised both our flagship router the MX and our security range the SRX in to virtual version that you can use in an on demand model in any Data Centre
Unlike some vendors, our SDN solution is not tied to specific hardware
Juniper hardware has had open APIs using the Junos SDK since that allow it to be programmed by any controller
Juniper’s Contrail SDN controller is Open Source
Many other vendors only provide a single networking component (e.g. just switching)
Carrier class products for all of switching, routing and security in the Data Centre
Virtualised routing & security based upon the same code as the physical products
