According to Jesse Lipson, Vice President and Data Sharing General Manager for virtualization leader Citrix, the company's main plan for the smartphone and tablet market is to leverage its web interface, CloudGateway 2, to provide applications to mobile devices, including full support for native HTML 5, iOS and Android apps. Lipson acknowledges, however, that many companies are not yet ready for the MAM (mobile application management) paradigm. Instead, small and medium-sized businesses are just beginning to dip their toes into mobile workflow by adopting MDM (mobile device management) systems.
Building a private cloud using the Citrix XenServer system can be accomplished in just four simple steps.
Businesses and other organizations interested in moving some of their IT functions onto a cloud-computing platform have several software options to choose. One of these is CloudStack 3 from IT company Citrix Systems, which is now available in a beta version. A full production version of the platform is anticipated by the end of next month.
All virtualization systems must have some way of addressing the management of stored resources. The three main virtualization platforms used in business environments today are Citrix, VMware, and Hyper-V. In some ways, all three systems use similar approaches to address storage management needs. One common technique shared by all three is RDM, also known as Raw Device Mapping. All three also retain the capacity to write either directly to stored resources or to a file instead. Likewise, all three can make use of dedicated file systems.
As more and more IT departments in small and medium-sized businesses begin to consider desktop virtualization as a viable way to reduce costs and increase efficiencies, the issue of compatibility has become more important. Desktop virtualization is useful because it can allow workers to access their data from any internet-connected location, and in a form that is entirely familiar because what they see is the usual desktop environment they would use at work.
Telecommuting has been in existence for decades, but only with the advent of the internet and then later, true virtualization technologies, has it become a truly viable option for many small and medium sized businesses. According to a recent study, companies may be able to save as much as $20,000 in costs per employee who works from home. This represents a strong return on investment that makes the effort of switching into this mode well worth the time and funding it will require.
A managed services model for IT services using the private cloud suite available from Citrix Systems is a powerful way to create a virtual environment that makes use of a physical infrastructure hosted in a data center, rather than taking up space in corporate or branch offices.
Virtualization expert Citrix has announced the launch of new IT solutions targeted to assist small and medium businesses. These solutions are designed to help such businesses make the leap into desktop virtualization. One key element of this SMB initiative is Citrix VDI-in-a-Box, which the company is promoting as a virtual desktop "all-in-one" solution. When combined with cloud-based support from a managed services provider, VDI-in-a-Box will allow those providers to support and monitor the deployment of virtual desktops from remote locations. This opens up the possibility of remote managed services personnel assisting with deployments at several different branch offices operated by a company, for example.
According to virtualization experts Citrix, new advances in chip technology are poised to create a situation in which virtual desktops can be deployed at lower cost than traditional physical desktops. The key development responsible for this leap forward is a chip designed by Citrix. Known as the HDX, it incorporated an arrangement that allows for a "system on a chip”. Texas instruments will produce the HDX chips, which will be used in a wide variety of commercial devices.
In the last few years, the hypervisor vendor VMware has made great strides in providing a simple and consistent way to protect application data stored on virtual servers. HP Data Protector, for example, is a software package that works seamlessly with the VMware platform to enable rapid and reliable security of the virtual servers users create with VMware.
Citrix, an industry leader in software providing virtualization platforms, has released an upgrade to its popular XenServer program. XenServer 6 has been optimized to work even better with cloud infrastructure and features enhanced scalability and better performance for both networking and virtualized desktop use.
In addition, the new version of XenServer will allow users to link into System Center Virtual Machine Manager's 2012 Console, a feature eagerly awaited from Microsoft.
XenServer 6 is still based on Xen hypervisor version 4.1, but includes new features that should prove of use to enterprise users. One of the most exciting is the use of Open vSwitch as the network stack. Since Open vSwitch now manages the stack by default, virtual networking features can be distributed network-wide. These include programs such as RSpan, NetFlow, and a variety of security ACLs.
A managed programs approach that includes installation and maintenance of XenServer 6 will allow business enterprises to scale out to the cloud. One strong feature of scaling out in this way is that users can continue to maintain close integration with existing Citrix products such as NetScaler, which helps optimize the use of wide area networks or WANs. Another added feature will allow XenServer host computers as well as virtualized machines to be remotely managed by the Microsoft System Center mentioned earlier. This provides users with an alternative to VMware's competing vSphere product. The XenServer 6 system, when used with the System Center, will allow users to create and utilize private clouds.
In many businesses and particularly in small to medium-sized enterprises, IT budgets can be very tight, with departments and on-staff support personnel eager to save money in any way they can. The temptation, therefore, to choose a free data storage solution can be quite strong. Companies now exist that offer free storage server software, but there are several compelling reasons why enterprises are actually better off opting for a managed programs approach to server functions.
Two basic kinds of computers used in business today go by the terms "thin client" and "fat client." A fat client is a typical computer. Though it may be attached to a network either wirelessly or with infrastructure such as Ethernet cables, a fat client can also function as a standalone workstation because it possesses all the resources it needs to do its tasks. These resources include hard drives, memory chips, and computer power in the form of microprocessors.
