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.

Xen Virtual Desktop

One of the latest trends in business desktops are virtual desktop. Citrix Xen desktop playing major role here. It delivers any desktop, any user and any location. In today’s business environment mobile employees are more. Where ever user moves he gets all the access. Managing or setting up small offices with physical desktops are highly expensive. This is one of the challenges addressed by virtual desktops. Power and cooling requirement. Earlier the delivery quality and speed of virtual desktops was bad. Now the access speeds increased, delivery quality matured. Antivirus, patch management, deployment of new applications, setting up of new work stations. These are the areas we have major savings. Once we deploy virtual desktops. Virtual desktops accessible from laptop, smart phones and other smart devises. This is one of the major IT cost saving technology.

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.

TelePresence

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.

Cloud Infrastructure

I was reading through the could infrastructure. It’s going to change the way we work with infrastructure. For me as an infrastructure professional it’s change the environment. Very easy to build the systems. Easy access, easy disconnection and lot more change the way we manage.

My end user desk tops are from cloud. My server’s and application’s are from cloud. I will be keeping a big pipe WAN link, dump terminals, telephones, and LAN connections of these. The entire infrastructure is from cloud. Applications are browser based. All the applications are accessed through an integrated area or form a portal. All the infrastructure is managed cloud provider. Locally no server, no data, no application. More and more mobile workers. Good to see more……

Desktops and Notebooks Operating System

It’s been quite long period people are tied with windows operating systems in desktops and notebooks. It’s user interface, installation, support of application, integration, drivers, devices, etc. Now the technology changed. People awareness changed requirement and way of access changed. This week I installed Ubuntu 10.10 in my notebook. It’s extremely awesome.

OS appearance changed, using Ubuntu font. E-mail, chat and micro blogging integrated. Installer is simple and faster. The trend shows more organisations and individuals will adapt the new OS.

Server Virtualization

Server Virtualisation

What is Virtualization?

Virtualization is a method of running multiple independent virtual operating systems on a single physical computer.  It is a way of maximizing physical resources to maximize the investment in hardware.  Virtualization technology is a way of achieving higher server density. However, it does not actually increase total computing power; it decreases it slightly because of overhead.  But since a modern $3,000 2-socket 4-core server is more powerful than a $30,000 8-socket 8-core server was four years ago, we can exploit this newly found hardware power by increasing the number of logical operating systems it hosts.  This slashes the majority of hardware acquisition and maintenance costs that can result in significant savings for any company or organization.

When to use virtualization

Virtualization is the perfect solution for applications that are meant for small- to medium-scale usage.  Virtualization should not be used for high-performance applications where one or more servers need to be clustered together to meet performance requirements of a single application because the added overhead and complexity would only reduce performance. 

While some in the virtualization industry like to tout high CPU utilization numbers as an indication of optimum hardware usage, this advice should not be taken to the extreme where application responsiveness gets excessive.  A simple rule of thumb is to never let a server exceed 50% CPU utilization during peak loads; and more importantly, never let the application response times exceed a reasonable SLA (Service Level Agreement).  Most modern servers being used for in-house server duties are utilized from 1 to 5% CPU.  Running eight operating systems on a single physical server would elevate the peak CPU utilization to around 50%, but it would average much lower since the peaks and valleys of the virtual operating systems will tend to cancel each other out more or less.

 

 

Physical to virtual server migration

Any respectable virtualization solution will offer some kind of P2V (Physical to Virtual) migration tool.  The P2V tool will take an existing physical server and make a virtual hard drive image of that server with the necessary modifications to the driver stack so that the server will boot up and run as a virtual server.  The benefit of this is that you don’t need to rebuild your servers and manually reconfigure them as a virtual server—you simply suck them in with the entire server configuration intact!

So if you have a data center full of aging servers running on sub-GHz servers, these are the perfect candidates for P2V migration.  You don’t even need to worry about license acquisition costs because the licenses are already paid for.  You could literally take a room with 128 sub-GHz legacy servers and put them into eight 1U dual-socket quad-core servers with dual-Gigabit Ethernet and two independent iSCSI storage arrays all connected via a Gigabit Ethernet switch.  The annual hardware maintenance costs alone on the old server hardware would be enough to pay for all of the new hardware!  Just imagine how clean your server room would look after such a migration.  It would all fit inside of one rack and give you lots of room to grow.

As an added bonus of virtualization, you get a disaster recovery plan because the virtualized images can be used to instantly recover all your servers.  Ask yourself what would happen now if your legacy server died.  Do you even remember how to rebuild and reconfigure all of your servers from scratch?  (I’m guessing you’re cringing right about now.) With virtualization, you can recover that Active Directory and Exchange Server in less than an hour by rebuilding the virtual server from the P2V image.

Licensing and support considerations

A big concern with virtualization is software licensing.  The last thing anyone wants to do is pay for 16 copies of a license for 16 virtual sessions running on a single computer.  Software licensing often dwarfs hardware costs, so it would be foolish to run a $20,000 software license on a machine on a shared piece of hardware.  In this situation, it’s best to run that license on the fastest physical server possible without any virtualization layer adding overhead.

For something like Windows Server 2003 Standard Edition, you would need to pay for each virtual session running on a physical box.  The exception to this rule is if you have the Enterprise Edition of Windows Server 2003, which allows you to run four virtual copies of Windows Server 2003 on a single machine with only one license.  This Microsoft licensing policy applies to any type of virtualization technology that is hosting the Windows Server 2003 guest operating systems.
