Why Hybrid Clouds Look Like my Grandma’s Network?

Do you think hybrid clouds look like your granny’s network too? Well, that may be extreme, but there is no doubt that hybrid clouds are networked in ways we saw things connected a decade back. Consider a recent example I came across while discussing cloud adoption at a large global enterprise headquartered in the US. Their Asia office wanted to deploy a regional application for local use. It was impractical to deploy it at one of the two large data centers in the US since user experience would be sub-optimal due to latency issues. Hence they chose a local cloud provider to host the application. Sort of a hybrid cloud situation. So what? Read More »

Service Providers Continue to See Value of Hosted Unified Communications and Collaboration Services

If there was ever a doubt that our service provider customers did not see the market opportunity to leverage the cloud and deliver enterprise collaboration services to their business customers, that uncertainty continues to decline.

Today, AT&T announced the availability of its Unified Communications Service, a new way for its business subscribers to offer a complete collaboration suite of features to employees in a secure and cost effective way. At the heart of AT&T’s enterprise collaboration solution is Cisco’s own Hosted Collaboration Solution, the foundation that many other providers such as Verizon and Orange have turned to, in helping them offer the best customized collaboration solution to their enterprise customers. Cisco Hosted Collaboration Solution gives partners, including service providers and integrators, the ability to deploy multiple collaboration applications on one server in a virtualized environment and then host those applications for multiple client organizations. The solution is designed to be run from partner data centers. Read More »

How Are Large Enterprises Utilizing Collaboration in the Cloud?

Today, we ‘re featuring a guest post from Brian Blatnik, a senior manager within Cisco’s Collaboration Technology Group:

In the month since our CloudVerse announcement the notion of a world of many clouds – public, private, and hybrid – has resonated with our customers, partners, and industry analysts. I’d like to share some perspective on how those types of clouds address different customers in the collaboration cloud services market. Since last month’s announcement highlighted our private cloud model in that market, Hosted Collaboration Solution for Large Enterprises, I’ll focus on that model. As a reminder, the Cisco Hosted Collaboration Solution gives partners, including service providers and integrators, the ability to deploy multiple collaboration applications on one server in a virtualized environment and then host those applications for multiple client organizations. The solution is designed to be run from partner data centers.

I’m often asked, “Haven’t enterprise voice and other UC services always been delivered from what we now call a private cloud?” It’s true that IP PBXs and other UC servers, like their PBX predecessors, provide services to users from a remote room or facility via a network. But there are two ways in which today’s cloud service delivery differs. First, there is the efficiency of pooling computing, network, and storage resources across multiple locations and services. Second, the services can be delivered in an on-demand fashion with elastic scaling.

The financial and strategic benefits deriving from these two factors are leading many businesses to consider consuming collaboration services in a utility model from Cisco’s partners in the Hosted Collaboration Solution (HCS). But the same drivers can result in substantial benefits to businesses that aren’t looking for services from a third party’s public cloud. Read More »

FHRP – Egress Path Optimization from the Server to the Client

I previously discussed using LISP to optimize your client-server traffic so today I’ll discuss the reverse direction: Egress Path Optimization from the Server to the Client. Let’s go over the need for Path Optimization in the direction from Server-to-Client with some pictures and explanations.

The Virtual Machine (VM) server is configured with a default gateway IP address, 192.168.1.1, which is the next hop IP address that the VM will forward packets towards as the traffic returns to the client outside the data center.  In this data center environment, we’ve deployed the default gateway using the First Hop Redundancy Protocol (FHRP).  In reality, FHRP is an umbrella technology term that includes Hot Standby Routing Protcol (HSRP) and Virtual Router Redundancy Protocol (VRRP), two main technologies that provide transparent failover and redundancy at the first hop IP router.  Please see info on FHRP here.

Also notice that the VM default gateway is the same as the HSRP Virtual IP Address (VIP). The HSRP VIP binds itself to one of the physical HSRP Routers via an HSRP election process using Layer 2 control packets between the two physical HSRP Routers and this means that the VM default gateway, since it points to a VIP, may move between physical HSRP Routers, and of course which is then intent and design when using any type of FHRP.

In the above picture, the Path is Optimized from Server to Client, so now let’s take a look at what happens when we migrate the VM to the new data center.

I can see clearly now!

Hopefully everyone is back from the Christmas/New Years Holidays by now and already hit the deck running. I know we in the Manufacturing team are already off, well, most of us. I started the New Year by having cataract surgery. So I am going to combine some Healthcare with some Manufacturing in this blog. Consider yourself forewarned!

First, what to expect from us this coming year: much more on the value of mobility and the ability to collaborate across the global workforce, wherever they are (yes, that is Borderless Networks); then a lot on the vast amount of data presenting itself to the factory and from the factory to the enterprise (you will hear the term “data deluge”); also the impact of “the cloud” on the factory; also the growing prevalence of tablets and other smart devices in manufacturing operations. And we will undoubtedly have new areas of concentration throughout the year as new technologies take hold in manufacturing.

So, that is the preview of the year. But now I want to talk about my personal experience with Healthcare and how it relates to Manufacturing. Read More »
