ITD: Load Balancing, Traffic Steering & Clustering using Nexus 5k/6k/7k

best

Data traffic has grown dramatically in the recent years, leading to increased deployment of network service appliances and servers in enterprise, data center, and cloud environments. To address the corresponding business needs, network switch and router architecture has evolved to support multi-terabit capacity. However, service appliance and server capacity remained limited to a few gigabits, far below switch capacity.

Cisco Intelligent Traffic Director (ITD) is an innovative solution to bridge the performance gap between a multi-terabit switch and gigabit servers and appliances. It is an hardware based multi-terabit layer 4 load-balancing, traffic steering and clustering solution on the Nexus 7000 and 7700 series of switches.

ACI Walkabout at CiscoLive 2014, San Francisco

In a few days at the Moscone Center in San Francisco, we will be celebrating the 25th anniversary of Cisco Live. This year we are expecting record attendance exceeding 20,000 participants, 9 amazing keynotes, 600 sessions, live demos at world of solutions, big analyst and partner presence, and last but not least, the opportunity for you to meet and network with top minds in high-tech. If you are new to Cisco Live and feel overwhelmed by the grandness of the event, let me assure you that you are not alone.  I have been there before. I have set out in this blog to give you an easy walkabout of Cisco Datacenter highlights, particularly the Cisco ACI key activities over the duration of the event.

Much like you I will also be eagerly looking to attend John Chambers’ majestic keynote that starts the proceedings on Monday, May 19. John in his unique style will lead with the Theme “Tomorrow Starts Here” covering leading industry trends such as Internet of Everything (IOE), Fast IT, and Application Centric Infrastructure (ACI) among many others. So, do not miss this opportunity. I want to shift gears and take you on a fast cruise of Cisco Data Center and Cisco ACI highlights at the event.

In less than a year since the announcement, Cisco ACI has taken the industry by storm with a large customer base  and several of the industry’s key partners such as Microsoft, Red Hat, Citrix, F5, et al endorsing and building joint solutions. There is so much excitement around ACI at this year’s Cisco Live. I want to give a structure to how I am planning to cover the topic in this blog. Essentially, I consider them as Cisco-led and Partner led.

Cisco has a packed agenda of ACI activities and announcements. Cisco APIC, which enables ACI Fabric mode on Nexus 9000 networks, will be available this summer along with a robust Go-To-Market (GTM) strategy that includes additional eco-system partners, Cisco Validated Designs (CVD), additional platform support and leading-edge hardware innovations across the portfolio. We are also introducing two new additions to the existing portfolio of Nexus 9000 to meet scalability, flexibility and performance requirements of standalone and ACI mode deployments.

Executive ACI speaking sessions feature prominently this year with Cisco President Rob Lloyd’s session “Infrastructure for the Agile Enterprise” keynote, May 20, 10 AM, at the North Hall.  Rob’s keynote also features Soni Jiandani, who will present how ACI delivers agility. Rob Soderbery and Soni Jiandani are presenting a technology trends keynote (GENSK 1109) on May 21, 8.30 am, titled “Fast Track to Fast IT: Cisco’s Application Centric Infrastructure”, another choice from a catalog of exciting offers.

Introducing OpFlex – A new standards-based protocol for Application Centric Infrastructure

Continuing on its tradition of contributing and committing to open source and open standards over the last 25 years, today Cisco announced “OpFlex” – a new open standards-based protocol for Application Centric Infrastructure that has been submitted into the IETF standardization process. We believe this will accelerate multi-vendor innovation in data center and cloud networks to drive operational simplicity, lower costs and increased agility.

Why is this required?

Traditional SDN models today function on the basis of an imperative control model with a centralized controller and distributed network entities that support the lowest common denominator feature set across vendors such as bridges, ports and tunnels. As the network scales, the controller becomes a bottleneck due to the need to maintain increased state, and starts to impact performance and resiliency. Likewise, because the applications, ops and infrastructure requirements need to be translated into network configuration, it impacts agility and introduces a manual learning process, requiring app developers to describe their requirements in low-level constructs.

If we contrast that with the vision of the ACI model with the Application Policy Infrastructure Controller (APIC), ACI adopts a declarative management approach. This model abstracts applications, operations and infrastructure providing simplification and agility. By distributing complexity to the edges, it also increases better scalability, and allows for resiliency – i.e. the data forwarding can still continue to happen even if there is no controller. It further provides ease of use with self-documenting policies automatically deployed or cleaned up from devices as necessary. All of these help circumvent the issues seen in traditional SDN models.

For this declarative model to work across a multi-vendor environment, to translate and map policy definition into the infrastructure, there has hitherto been no standard protocol to do that across physical/virtual switches, routers and L4-L7 network services. This vacuum has led to the development of “OpFlex” – a new open standard recently submitted to the IETF.

Who is contributing to OpFlex?

Several industry leaders and practitioners are actively involved in the standardization process. These include Microsoft, IBM, Citrix and SunGard Availability Services, in addition to Cisco.

Application Centric Infrastructure (ACI) Includes Strong Ecosystem for Security and Network Services

November 8, 2013 at 1:00 pm PST

partnersWhen Cisco designed the concept of an Application Centric Infrastructure, we knew it wouldn’t reach its full potential without drawing in a very comprehensive ecosystem in a number of areas. Perhaps the most impressive aspect of our announcement was the breadth, quality and scope of the data center infrastructure vendors that we aligned so quickly with our ACI vision and that contributed their perspectives to the launch, and will be contributing key solutions to Cisco’s infrastructure-wide vision.

Yesterday, I blogged about the role of application controllers, network monitoring solutions, WAN optimization, firewalls, etc. have in setting up application networks, provisioning applications, and how the ACI policy model incorporates these security and services solutions. I wanted to follow up that post with some highlights from the support we received from some of our ACI ecosystem vendors in this area, that incorporate ACI policy support into their security, application delivery controller, load balancing and other solutions.
