The public cloud is geared more for the individual consumer or small company, while the private cloud is geared more for a medium-to-large company. In addition, the private cloud is branching out to incorporate the ability to have some data and applications serviced from the public cloud. This white paper examines the different types of cloud computing and shows what cloud computing can offer you.

Cisco Collaboration Systems Release (CSR) 10.6, along with CUCM 10.5(2), enhances the user and administrator experiences and interactions. In many cases, a change to one product may necessitate changes to other products. For example, where the deployment options for video conference control changed to place all control behind the Telepresence Conductor, Cisco Prime Collaboration management tools had to be updated to reflect this new deployment approach. As new endpoints are added, CUCM and Prime Collaboration both needed to be updated to reflect the new endpoints.

If you are starting a new desktop virtualization project, it would be wise for you to take the time to explore your options and compare VSAN to other options.

Here are some secrets, tips, and tricks for virtualizing your datacenter. We want to introduce some best practices for virtualization, while not being too biased towards one virtualization vendor or another. We'll use some common examples of products and tools that work with VMware's vSphere and Microsoft's Hyper-V, but with an eye toward virtualization in general, and not the specifics of any of the capable platforms that could be used). We will assume, however, that bare metal hypervisors, in other words virtualization platforms where the hyper visor is the OS, will be used as opposed to running a hypervisor on top of an existing general-purpose operating system (which is great in a lab, but terrible for data center projects).

These five "secrets" to virtualizing desktops will greatly increase the chance of a successfully VDI implementation. It is very important to plan for this; to balance the hardware environment to handle not just average but peak load; to properly size storage, not just for capacity, but for performance as well; to minimize the number of base images so that the costs of maintaining each can also be minimized; and to accept and embrace the fact that people will connect with a wide variety of devices, and to create a plan to accommodate as many of these devices as is feasible at the lowest cost.

Mobile payment systems have solid promise to become the dominant means of financial transactions, but there are some hurdles to overcome. Apple Pay might be the dominant force today, but Google Wallet and others are not far behind. The year 2014 was when digital and mobile payment systems became known to a wide range of the general population, while only techno-enthusiasts were aware of the options in the four to five years prior. Thus, mobile payment systems are not new, but customers and merchants are quickly adopting them now that they have become popular. It still remains your responsibility to thoroughly research any mobile payment option before implementing it. It is your money and you have the burden of ensuring that it has the best protection possible.

A local area network (LAN) provides a path of communication, allowing the delivery of packets of data, voice, or video originating from the sender (logical source address) to the receiver (logical destination address). Ethernet is the most common LAN used. As you start to learn about networking, remember that communication and the movement of large numbers, whether it is people, cars, mail, or network traffic, have a commonality. Everything you know and use in your daily life can be compared to the way traffic moves.

The OSI model is a conceptual tool used to discuss and describe network functions. The use of a standard reference model is essential to communicate ideas as well as create new technologies.
