What is “the Cloud”? And what is it not?

The Cloud – One of the hottest buzzwords and most abused in describing products or services recently. In this article I would like to mix facts with personal experiences I made, in order to assist everyone, who would like to find out what the cloud is and does and the things that is does not do (hence the title). Cloud has been buzzing around for a while now but when I witnessed both my parents talking about “the cloud” and how they use it in private I understood that this technology has arrived in mainstream and it is here for good.

Cloud??

So what is the cloud in few words? The cloud, or cloud computing is a technology design to enable users working with solutions independent from device, location and network. Of course there are specialisations with a larger or smaller focus on one or two subjects but in general this is it.

Origin of the Term

There are many theories on the origin of the term, yet there is no proven story. Feel free to check some good options on the Wikipedia article for cloud computing. My theory is that it developed from the use of cloud clip-arts and stencils in technical drawings or presentations, created to visualise a network setup. I am sure that even before the term became a buzzword, most of you have seen presentations with little black boxes, switches and routers in and around a large cloud to set a virtual border between realms.

Is the Cloud something new?

I am afraid it is not. The ideas and designs for such concepts have already been around since the 1950s but like with many breakthroughs in the user world, it required certain cultural and technological thresholds to be reached before the adoption could take place on wide-scale.

What is the Cloud?

  • Agility – The cloud is agile and therefore allows users to upscale or downscale their service based on business demand. Further the actual hardware, used to host a virtual machine, can be re-purposed if necessary. This is however not a cloud-only benefit, please read further down on infrastructure virtualisation.
  • Availability – Services have the technological possibility of being available independent from devices, network and location. This is of course relative to the design of each service along with its purpose but technically this is no limitation. For instance you can use cloud video conferencing services to join any enterprise-grade video conference call from your smartphone, notebook, office workstation, tablet or even from a private computer at your home or maybe somewhere else. Of course your conference partner needs to have their own environment set up to accept connections from outside in general. Cloud technology is not a wall-breaker and cannot bypass security of an organisation, if they don’t allow such connections by policy.
  • Business Continuity – Cloud services are set up with redundancy and failover automation in place. So that even if single devices would fail, users would not notice and can proceed using the service. Such reliability would traditionally cost a lot of money when investing in owned or dedicated infrastructure black-boxes.

What is the Cloud NOT?

  • Cloud = VirtualisationVirtualisation of infrastructure is a great way of deploying new solutions and upgrading your environment. But if you do this within your WAN this does not automatically mean you are using the “cloud”. You are just virtualising your infrastructure. Fair and square.
  • “No more hardware” – Well that’s a lie. Using software solutions or virtual infrastructure there will still always be servers and databases that require a physical body. Only the deployment and usage is changed but there will always be hardware. You might not own the hardware and you will most likely never see or touch it but it’s there, somewhere in a physical data centre.
  • Grid computing – No, grid computing is not the same as cloud computing in my opinion. Even though, it might be its scientific opposite. Where grid computing allows many computing units to work on a common target (e.g. movie rendering in render farms or Bitcoin mining), cloud computing allows a single user to utilise just any infrastructure in the pool offered by the cloud service provider to achieve their objective.
  • “Private Cloud” needs to be on-premises – No that’s not correct even though it seems to be a common assumption. A cloud service can be deployed dedicated for your organisation without anyone else having access to it, but the location of the physical hardware is irrelevant in order to provide that. In most cases the service provider will utilise hardware that is physically near to the user base in order to avoid performance issues that could occur on long “open internet” routes.

Challenges of Cloud Technology

  • Security – Any cloud service can be set up in secure manner if the solution and the environment of the clients allow it.
  • Privacy – Yes, privacy is a hot topic nowadays. But actually, it always were even in pre-internet age. Privacy is nothing impossible even in the cloud, even in the internet if you choose the right service provider. And if you are looking for good providers but affordability is a concern, make sure that your selected partner has a few good reference clients to show-case to you.
  • Compliance – When you are in phase 2 of the provider selection, bring in the techies of your organisation to make sure all offered functions and features are compliant to any active IT security policies that you need to consider.
  • Vendor Strategy – Cloud providers equal single vendor lock-in? Yes, it can be the case but if you want to avoid that, talk about this particular subject with your provider candidates. A few providers out there have established alliances and offer support to avoid any lock-ins.
  • Online works, offline it doesn’t – Depending on what your solution looks like make sure that your workforce  can use the solution when they are online and when they are offline. For instance when changing a file being on a flight, the data should update and synchronise itself in the cloud again when they are online. However there are some services which this does not apply to such as real-time communication (e.g. WebRTC, video conferencing, VoIP telephony, instant messaging).

Examples of Public Cloud Solutions

Summary

I hope this cleared some confusion around cloud terminology and technology. Further I hope it helped you through your process of picking a good service provider for your organisation if that was your objective. Further I would like to thank Simon Dudley of LifeSize and Phil Karcher of Forrester Research for hosting the webinar, which sparked the inspiration to write this article. LifeSize is often arranging interesting webinars and announces them on their social media platforms. Maybe I will see you on their next event – until then.

The Benefits Of Wide Area Networking Using Cisco Technology

Long before the internet became the phenomenon that it is today, Cisco was providing networking solutions, so efficiently that it has become the world leader in computer, IT and communications networking. In fact, the company has become a household name, recognised even by people who haven’t a clue what Cisco does. This is why, to those who are in the know, Cisco technologies are the perfect choice when planning Wide Area Networking (WAN) solutions for anyone from home users to corporations operating around the globe.

Cisco Offers Bespoke Solutions

One of the most appealing advantages of using Cisco Technologies for WAN is the company’s flexibility to tailor its networking products and solutions to customers’ specific needs, meaning no prospective customer is only offered the choice from a range of off-the-shelf options. This also offers the scope for growth and future updates without installing a complete new system.

Connecting Through Switching

Wide Area Networking using Cisco Technology is where the company comes into its own. While many other providers have moved into the smaller Local Area Network and Personal Area Network markets, Cisco have undoubtedly looked at the big picture for the future and provide a service that is used and trusted across the globe. From a base or local station, information sent to a remote geographical location must travel via one or more WAN links, connected through switches that are dedicated to sending the information. A computer in London, for instance, would communicate through a router to a WAN that then sends the data to a router in, say, Munich, Montreal or Mumbai. Three different technologies, cell switching packet switching and circuit switching, are used, each with its own advantages, disadvantages and optimum uses.

Benefit From Unbeatable Flexibility

At the heart of all of the company’s products and solutions is the Cisco Internetwork Operating System, or Cisco IOS. The IOS brings together diverse and different systems and devices to integrate varied protocols into a cohesive whole system. The integration of all components of the network increases security, as well as speed and quality of communication. With these solutions available, network designers can work more freely and flexibly, delivering solutions to their customers in a smooth process.

Modern Communication with Cisco TelePresence

Using high-end video conferencing technology Cisco was among the first organisations to produce TelePresence infrastructure and endpoints alike. With the Immersive TelePresence suites they have reached a milestone that was unparalleled until now allowing important meetings to be carried out with participants from around the world with the same effectiveness as if they were all in the same room.

Cisco Technology Is Future-Proof

One reason that Cisco technologies lead the world is that the company has never stood still. It has acknowledged advances in technologies in networking and connectivity, which means that the company is trusted by a wide pool of users. Consumers and network specialists look to Cisco for future developments. Cloud technology is the latest development to have captured the imagination, but it will not be the panacea it is predicted to be without the nuts and bolts of everyday use. Whatever comes out of the cloud in the future, integrating WAN with Cisco technologies gives its users optimum usage out of their broadband and network to do their own jobs with the maximum of efficiency, while Cisco runs the system unobtrusively under the bonnet.

Deutsche Telekom discontinues VideoMeet

The cloud video conferencing solution VideoMeet by Deutsche Telekom in corporation with Blue Jeans Network is now confirmed to be discontinued by end of the year. The decision was first published by the German  expert magazine “Telecom Handel” in an online article yesterday by Waltraud Ritzer.

What is VideoMeet?

The solution was designed to bring different types of video conferencing devices and software clients together with Blue Jeans cloud technology. The VideoMeet solution was first introduced in June 2011 and has seen strong marketing campaigns. In addition to the virtual MCU and the interop between systems of many different vendors, Blue Jeans technology was first to natively bridge Skype participants into professional video conferences. In 2012 more compatibility features were announces such as the integration into Microsoft Lync or using the service directly out of the Browser with WebRTC.

What’s next?

Starting from January current users can switch to a new model by Deutsche Telekom, which is yet to be announced, or get the service directly from Blue Jeans. Spokesperson Marion Kessing says that unlike the cloud solution VideoMeet, Immersive Telepresence and other video conferencing options of Deutsche Telekom will be extended.

Next to the user base this also hits redistribution partners as they will have to find an alternative cloud video conferencing solution for their clients and integrate it into their service portfolio before January. Seeing the increasing demand for cloud video conferencing a complete removal of the service is unlikely.

Cloud video conferencing alternatives?

Users and redistributors alike might now be interested in alternatives such as examples that can be found on our recent cloud video conferencing solution comparison. In addition to that of course like always we would love to hear your opinion and the experiences you have made.
