Yesterday, Nov 6, Cisco unveiled details of the Application Centric Infrastructure with an ecosystem of partners that share our common view -- IT is in need of a transformation to create the Application Economy. Some key technology leaders spoke about the application lifecycle impact of an open and centralized policy model for complete infrastructure automation, including configuration, operation, monitoring, and optimization. I’d like to recap a few of those comments here today.
During the ACI announcement, Brad Anderson, Corporate Vice President in Microsoft’s Windows Server and System Center Group (WSSC), said that
virtualization has unshackled applications from the hardware in the past. But now with ACI we can do much more.So first of all, we can have the applications be able to describe their needs for more rapid provisioning. So with the view we can get across physical and virtual, we can see what is happening with the application, we can optimize the infrastructure for the application, and do more rapid troubleshooting.
…the integration with Microsoft cloud OS and UCS is really remarkable. Literally you have a common way to automate everything from the application, down to the operating system, down to all of the hardware level components. But ACI gives us the ability to do some really remarkable things..
Imagine how Exchange, Sharepoint and Linc -- being able to be shipped with ACI policies that now describe out how exactly the network should be configured, how it should be optimized, and automatically be provisioned across physical and virtual in a holistic way. That’s the kind of value we are going to be able to deliver together.
“…These new solutions are designed to improve business agility and reduce cost by driving infrastructure automation in support of core business processes and applications. This next-generation infrastructure will deliver increased application performance, resource pooling, visibility, automation and mobility through:
· Converged ACI stacks that include fully integrated versions of Windows Server 2012 R2 Hyper-V, System Center 2012 R2, SQL Server, Exchange and SharePoint”
I introduced the IT challenge posed by apps that behave differently in my earlier ACI post so now I want to point out that the new converged ACI stacks will fully integrate the operating system, orchestration, applications, server and network infrastructure to provide an enterprise customer with the application agility to rapidly deploy Exchange, SQL Server, and SharePoint, scale and upgrade them, and also to decommission them.
Many next generation distributed cloud applications are being written on open source platforms. For a view on what ACI means to a leading open source cloud platform, OpenStack, let me quote what Jim Whitehurst, President and CEO of Red Hat, said at the launch:
…there’s a whole set of functionality that is required to run a portfolio of true production applications and be able to run a diverse set of applications and to make sure that you can actually guarantee the performance levels that you need. The great thing about ACI is it provides that really differentiated functionality that enterprises need, even on open platforms, but at the same time, it does it with open standards, open APIs, and an open ecosystem so that customers get the benefit without being locked in and maintain the flexibility they are looking for going forward.

This year Cisco held Data Virtualization Day 2013 at the New York Palace in New York City. With 350 attendees from more than 130 organizations, it marked the largest event to date and showcased data virtualization is top of mind for organizations as they try to extract more value out of their data.
Data Virtualization -- Different points of view
During the event, customers, analyst and Cisco executives gathered to share best practices, discuss trends driving data virtualization and provide insight into Cisco’s go-forward strategy to expand and accelerate data virtualization offers. Some highlights included:
Customers such as Goldman Sachs, BMO and British Sky Broadcasting shared insider’s views of their implementations, also explaining the significant profitability, agility, and risk management benefits their enterprises have achieved.
Top data virtualization analysts at Forrester and R20 Consultancy discussed data virtualization adoption acceleration as well as the business and technology trends behind it.
Looking ahead, Noel Yuahanna of Forrester described global information fabrics powered by data virtualization that integrate enterprise, partner, marketplace, social and line of business information fabrics to provide connected data anytime, anywhere. Rick van der Lans, R20 Consultancy, discussed how data virtualization along with powerful networks – which will allow data to stay where it is collected – will become the dominant data integration method.
Mike Flannagan, General Manager of Cisco’s Integration Brokerage Technology Group,discussed why Cisco chose to enter the data virtualization business and noted that the big data, cloud computing and “Internet of Everything” eras were making data virtualization a must have for Cisco’s customers.
Jim Green, General Manager of Cisco’s Data Virtualization Business Unit, presented his vision for data virtualization’s next generation and that achieving massive scale was the next frontier for data virtualization technology. He also discussed Cisco’s strategy to innovate using a unique mix of data virtualization, networking, and compute assets to meet this scale challenge.
Highlights from these presentations will soon be posted to our Data Virtualization Day resources page and the Cisco data virtualization offering page. So stay tuned.
In the ACI architecture, applications drive networking behavior, not the other way around. Pre-defined application requirements and descriptions (“policy templates”) automate the provisioning of the network – virtual and physical, application services, security policies, tenant subnets and workload placement. Automating the provisioning of the complete application network reduces IT costs, reduces errors, accelerates deployment and makes the business more agile.
Application Virtual Switches are thepurpose-built, hypervisor-resident virtual network edge switches designed for the ACI fabric. They provide consistent virtual networking across multiple hypervisors to simplify network operations and provide consistency with the physical infrastructure.
AVS is robustly integrated into the ACI architecture and supports Application Network Profile (ANP) enforcement at the virtual host layer consistent with the Nexus 9000 series physical switches.
AVS is managed centrally along with rest of the ACI fabric components through the Application Policy Infrastructure Controller (APIC) and provides advanced telemetry features to allow end-to-end visibility and troubleshooting capabilities across both virtual and physical devices, .
AVS enables optimal traffic steering between virtual and physical layers of the fabric to maximize performance and resource utilization. For example, if the web and app tier are located on the same host, AVS can route traffic or apply security policies between these end point groups within the hypervisor itself. On the other hand, if the database is a bare metal workload that is attached to the physical Nexus 9000, the application policy is consistently applied at the physical Nexus 9000 top of rack switches instead.
Application Centric Infrastructure with Application Virtual Switch
ACI eliminates the operational complexity of differences in managing virtualized environments vs. bare metal or legacy environments. It provides a consistent operational model across both AVS and Nexus 9000 respectively. ACI also allows for flexibility of placement of application workloads based on application requirements. Watch this short video.
If you have been following the news, I’m sure you saw that Cisco just introduced Application Centric Infrastructure (ACI). Combine ACI with Cisco UCS Director and you can provision and deliver application-centric infrastructure automatically.
Over the past 11 months, I have discussed how Cisco UCS Director reduces data center complexity with unified automation and management of multi-vendor converged and integrated infrastructure systems. But the provisioning of compute, storage and network resources is just the start. IT needs to deliver infrastructure that is tailor-made for the specific applications their users need. Together with ACI, Cisco UCS Director has key capabilities to make this happen.
What ACI has done is backed off from all the network complexity in trying to build more and more intelligence directly in the fabric. Building the network to be externally automated can centralize the intelligence and control, while simplifying the design and operations of the fabric greatly (also a goal of SDN, by the way). But what’s really new about ACI is that the programmability and orchestration of the infrastructure (how it takes the orders) is now done in a business-relevant policy language/model.
In a pre-launch post, I looked at why application policies were an ideal model to build infrastructure automation around, and how application policies are better suited to mirror business objectives and requirements than traditional IT infrastructure policies. The fact is that applications are the brains of the business and best reflect the activity and dynamic requirements of the business. Application policies are inherently business-relevant. The key benefits for customers end up being vastly greater degrees of automation, process improvement and business agility. [Note: It will be left as an exercise for the reader to prove that OpenFlow, e.g., is not a business-oriented policy language.]
