Google Cloud Connect for Microsoft Office

Google Cloud Connect for Microsoft Office is one of the collaboration services from Google. It’s really picking up market. It allows two or more people work together on the same file at the same time in Microsoft Office 2003, 2007 or 2010 on Windows PCs. For example, you can edit a Word document’s table of contents from one office while co-workers adjust formatting and make revisions from another office. Instead of bombarding each other with attachments and hassling to reconcile people’s edits, your whole team can focus on productive work together.

Cloud Computing World Forum Middle East and Africa in Dubai

I had a chance to attend the conference (09-03-2011). It was rich contented and lot of thought process in different angles. Its benefits, commercials, challenges, security, legal and future. One thing sure the drive is towards cloud, it’s private, public and hybrid. Cloud computing is there the time internet started or the mainframe started. Now the service delivery models changed. Tomorrow this service can call it as different name with some added value or modifications. Discussion of PaaS, IaaS, SaaS was fruitful and given thought of the service model. Cloud model has CAPX and OPX benefits. But it’s depends the maturity of the organization or how the approach is. Couple of challenges related to this region discussed about the connectivity, legal aspects and security. More and more players coming this market with different service design. The concept still to go for more maturity and definitions. Virtualisation, consolidation, thin clients are the couple of components making this journey. Anywhere any time access. Optimization and de-duplication also part in it.

Security Threats In VoIP

Users have been exposed to the risks of sending data over the Internet while at the same time having the expectation that telephone conversations are strictly confidential. Security issues in the data and voice networks are in fact very similar, but completely separate in the minds of most users. Major security concerns of VOIP networks.

• Phreaking
Phreaking is a slang term coined to describe the activity of a subculture of people who study, experiment with, or explore telecommunication systems. This is sometimes called the H/P culture (with H standing for hacking and P standing for phreaking). Through this making calls through another user network, putting cost to that person.
• Eavesdropping
Eavesdropping is how most hackers steal credentials and get important information like business data. Through eavesdropping, a third party can obtain names, password and phone numbers, allowing them to gain control over voicemail, calling plan, call forwarding and billing information.
• Vishing
Vishing is a party calling you faking a trustworthy organization (e.g. your bank) and requesting confidential and often critical information.
• DoS (Denial of Service)
DoS attacks can be carried out by flooding a target with unnecessary SIP call-signaling messages, thereby degrading the service.
• SPIT (Spamming over Internet Telephony)
SPIT attacks consist of sending a voicemail to a person, masquerading it with information from a party trustworthy to the receiver, like a bank or online paying service, making him think he is safe.
• Man-in-the-middle attacks
VoIP is particularly vulnerable to man-in-the-middle attacks, in which the attacker intercepts call-signaling SIP message traffic and masquerades as the calling party to the called party, or vice versa. Once the attacker has gained this position, he can hijack calls via a redirection server.

Technology and concept is changing day by day. New strategy and solutions. Interaction and integration is vital everywhere. To thrive in today’s economy, you have to collaborate with colleagues, partners, and customers around the globe at a moment’s notice. At the same time, you want to conduct your business in a way that enhances the quality of your relationships. Here are numerous applications for telepresence, ranging from corporate conferencing to remote surgery. It is actively used for both of these things, and can also be seen in the education field, using telepresence to connect educators, students, and professionals across varying distances. Some companies also use telepresence in dangerous spaces, such as under the sea or deep within the Earth, to allow employees to visit the site without putting themselves at risk. As the technology is refined, developers claim, people could use telepresence to visit archaeological sites without damaging them, or to take trips to distant regions.

Cisco DMVPN (Dynamic Multipoint Virtual Private Network)

DMVPN is a simple, secure, low cost, scalable VPN-Tunnel. DMVPN supports distributed applications including: data, voice, and video, with QoS. All of this can be done in a secure IPSec VPN tunnel over an Internet connection.  The only change is the IP address of the GRE Tunnel.  The spoke uses dynamic discovery of IPSec tunnel end-points, (other spokes). No IPSec static configuration for each spoke.

Because DMVPN supports multipoint GRE tunneling you can run VoIP, Video, and Multicast services across your secure DMVPN link. Hub-and-Spoke, (H&S) and Spoke-to-Spoke, (S2S). With H&S the design.

It’s a cost effective and secure communication for branch offices.

Unified Communication

Unified communication is an industry term used to describe all forms of call and multimedia/cross-media message-management functions controlled by an individual user for both business and social purposes. This includes any enterprise informational or transactional application process that emulates a human user and uses a single, content-independent personal messaging channel for contact access.

The essence of communication is breaking down barriers. In its simplest form, the telephone breaks distance and time barriers so that people can communicate in real time or near real time when they are not together. There are now many other barriers to be overcome. People can use many different devices to communicate (wireless phones, personal digital assistants, personal computers, thin clients, etc.), and there are now new forms of communication as well, such as instant messaging. The goal of unified communications involves breaking down these barriers so that people using different modes of communication, different media, and different devices can still communicate to anyone, anywhere, at any time.

Unified communication (UC) encompasses several communication systems or models including unified messaging, collaboration, and interaction systems; real-time and near real-time communications; and transactional applications.

  • Unified messaging focuses on allowing users to access voice, e-mail, fax and other mixed media from a single mailbox independent of the access device.
  • Multimedia services include messages of mixed media types such as video, sound clips, and pictures, and include communication via short message services.
  • Collaboration and interaction systems focus on applications such as calendaring, scheduling, workflow, integrated voice response, and other enterprise applications that help individuals and workgroups communicate efficiently.
  • Real-time and near real-time communications systems focus on fundamental communication between individuals using applications or systems such as conferencing, instant messaging, traditional and next-generation private branch exchanges.
  • Transactional and informational systems focus on providing access to m-commerce, e-commerce, voice Web-browsing, weather, stock-information, and other enterprise applications.

Cost Effective Communication

Recession gave me to start thinking about cost effective communication solution. In corporate and SMB environment communication cost is one of the major portion of operational cost. Communication can’t be avoided, so how we can reduce with using other effective solutions. Consider the legal aspects, cost of infrastructure, management, maintenance, expertise requirement.

In a run through the present office scenario, we have lot of single man office or mobile office. That too spread across. All the users required to access different services. Some of them are in house hosted or some of them are from internet. Companies are integrated the work flow through the devices. Here users are using different gadgets, laptop, soft phone, note book, Black Berry, I Phone, etc.

All the areas communication cost is an integral one. The ways of cost involved is different ways. Internet charges, telephone charges, leased line cost, ADSL cost, LAN phone cost, mobile phone cost.

Couple of Solution:-

  1. Office Communicator
  2. Open Source SIP based Unified Communication
  3. VPN over ADSL to ADSL
  4. BlackBerry

These are just high level of technologies, work each solutions depends on the size of organization, requirement, infrastructure availability, skill set. A detailed exercise required.  Out of the box, the solutions give you a major reduction in communication cost.
