Platform as a Service (PaaS)

Platform as a Service (PaaS) is a paradigm for delivering operating systems and associated services over the Internet without downloads or installation. PaaS is sometimes called "cloudware" because it moves resources from privately owned computers into the Internet "cloud." Platform as a Service (PaaS) is an outgrowth of Software as a Service (SaaS), a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over the Internet.

Ning.com, Google, Microsoft, Salesforce.com and Amazon are all offering some form of PaaS

Long Term Evolution (LTE)

Long Term Evolution (LTE) is a 4G wireless broadband technology developed by the Third Generation Partnership Project (3GPP), an industry trade group. 3GPP engineers named it "Long Term Evolution" because it represents the next step in a progression from GSM, a 2G standard, to UMTS, the 3G technologies based upon GSM. LTE provides significantly increased peak data rates, with the potential for 100 Mbps downstream and 30 Mbps upstream, reduced latency, scalable bandwidth capacity, and backwards compatibility with existing GSM and UMTS technology. Future developments could yield peak throughput on the order of 300 Mbps.

The upper layers of LTE are based upon TCP/IP, which will likely result in an all-IP network similar to the current state of wired communications. LTE will support mixed data, voice, video and messaging traffic. LTE uses OFDM (Orthogonal Frequency Division Multiplexing) and, in later releases, MIMO (Multiple Input Multiple Output) antenna technology similar to that used in the IEEE 802.11n wireless local area network (WLAN) standard. The higher signal to noise ratio (SNR) at the receiver enabled by MIMO, along with OFDM, provides improved coverage and throughput, especially in dense urban areas.

LTE is scheduled to be launched commercially in 2010 by Verizon Wireless and AT&T Wireless. T-Mobile and Alltel have also announced plans to roll out 4G capabilities based on LTE. These networks will compete with Clearwire's WiMAX for both enterprise and consumer broadband wireless customers. Outside of the US telecommunications market, GSM is the dominant mobile standard, with more than 80% of the world's cellular phone users. As a result, HSDPA and then LTE are the likely wireless broadband technologies of choice for most users. Nortel and other infrastructure vendors are focusing significant research and development efforts on the creation of LTE base stations to meet the expected demand. When implemented, LTE has the potential to bring pervasive computing to a global audience, with a wire-like experience for mobile users everywhere.

Communications-enabled Business Process

Communications-enabled business processes (CEBP) is the integration of communications capabilities into software-enabled business procedures, applications and technologies. CEBP enables communication between applications as well as between applications and humans to automate many components of business processes. The purpose is to optimize those processes and to ensure continuous, low-latency, real-time communications among the customers, suppliers and employees of an enterprise.

One of the better known CEBP vendors is Avaya Inc. of Basking Ridge, New Jersey, USA. The Avaya CEBP solution consists of a communications process manager, an event processor and software integration services:

• The communications process manager keeps track of data exchanged by business-related systems, flagging significant events.


• When an important or unusual event occurs, the event processor brings key players together using unified communications (UC) encompassing all available technologies such as conventional telephone, voice over IP (VoIP), cellular telephone, instant messaging (IM), texting and email.


• Software integration ensures compatibility among all devices, systems, technologies and programs to minimize conflicts, bottlenecks and delays, allowing decision-makers to do their jobs with a minimum of distraction.

VAR to VAR

VAR-to-VAR is a business model based on cooperation between value-added resellers (VARs) that allows the companies to obtain professional services and solutions that would not have been accessible to them otherwise.

Successful VAR-to-VAR partnerships expand geographic reach, tap each other's expertise and enhance the brainstorming process. Such cooperative ventures can increase the buying power of both companies and reduce overhead and production cost. By buying in bulk, VAR-to-VAR partnerships are sometimes able to negotiate pricing from suppliers of critical components. VAR-to-VAR partnerships have successfully challenged larger, consolidated enterprises for lucrative contracts when neither of the smaller companies could have done so alone.

VARs tend to be ideal clients for one another because they understand each other's service-related challenges. The ultimate result is good for the end user because it encourages the evolution of the best possible product. Nevertheless, some companies find the VAR-to-VAR paradigm difficult to accept, especially if their past experiences have involved rivalries with other players in their field.
