Understanding App Delivery Controllers in Hybrid Clouds

Many call Application Delivery Controllers (ADC) the next generation of load balancers.  Same as load balancers, they sit in front of web servers. In addition to providing the balancing services, they now help improve scale, availability, fault tolerance, security, and routing. But, not all ADCs are delivered as pure software solutions, designed for cloud-based and virtualized deployments, or work in hybrid cloud environments—items which are becoming mainstream requirements for the Software Defined Datacenter (SDDC) that VMware sees as the future of cloud computing.

Why care about the SDDC?

Industry leaders across the board are gravitating to hybrid clouds for lower costs, no lock-in, greater flexibility, increased speed, built-in disaster recovery, and new capabilities. Of course, there are more reasons, and all these reasons are driving the need to get to a hybrid cloud model. In Sandhill.com’s recent “Leaders in the Cloud” research study from 2010 (and updated in 2011), they said, “our study surveyed more than 500 IT executives and indicated that the biggest growth will be in hybrid clouds (from 13 percent now to 43 percent in three years).”

In order to achieve the promises of hybrid clouds, VMware sees the need for a completely software driven data center so your applications are portable across disparate architectures.  By removing hardware devices, and creating application architectures where all infrastructure is virtualized, delivered as a service, and entirely automated by software, companies can now effectively move apps across clouds to meet their needs.

Could You Consolidate Databases 13 to 1?

Over the last 18 months I have had the good fortune to talk to a lot of Virtualization Infrastructure Administrators on the subject of VMware and databases.  One of the things I hear the most is:

“We are 50% virtualized and our goal is to get to 75% this year.  To do that, we have to get a handle on our databases.”

While I appreciate the goal, this is easier said than done.  You see, I used to be part of the problem.

vFabric Usage and vFabric License Server

One change in vFabric Suite 5.1 is that the EULA now requires people to check their usage every 90 days. This is listed www.vfabric.co/eula – further below, there is an explanation on the simple way to get a report on this information:

At least once every ninety (90) days during the License Term (the ” Reporting Period”), You shall calculate, using all tools reasonably available to you, the average number of Virtual Machines in which You have run the Software during such Reporting Period (” Average Use”). If during any Reporting Period Your Average Use exceeds the number of licenses for which You have paid the applicable license fees, You shall: (i) report the excess use to VMware, within thirty (30) days of making the calculation, by providing written notice to vfabric@vmware.com; and (ii) pay to VMware, within thirty (30) days of the date of VMware’s invoice, the license fees due for such additional licenses. The day following an Average Use calculation shall begin a new Reporting Period.

The vFabric License Server makes it easy to get a quick view of license and product usage over time. The simplest way to find overall usage is to visit the web report interface. Simply enter the URL in a browser: https://host:8443/vfabric-license-server/report/create where host is the address of the computer in which you installed the vFabric License Server. You’ll see this page in your browser:
