Security and cost concerns are the biggest barriers in cloud adoption, according to the virtualisation, networking and SaaS firm.

Citrix has said that the common barriers to cloud adoption are security and cost concerns and it believes that through virtualised appliances and improved security, it can make cloud computing increasingly viable for enterprise customers. To help achieve this goal, the company has unveiled the Citrix Branch Repeater VPX and Citrix Access Gateway VPX as well as the availability of five new NetScaler Application Firewall appliances.

"Server virtualisation is enabling a new level of branch office service consolidation," said Joe Skorupa, Research VP Networking and Communications Data Center, Gartner. "WAN Optimisation Controller vendors are responding to this new opportunity by developing a variety of approaches that can reduce capital expenditure and operating expenditure for branch office IT services. As the requirement for additional services in the ‘serverless’ branch expands, virtualisation is key to avoiding box proliferation."

Troy Trenchard, Group VP and General Manager of the Security and Acceleration Product Group at Citrix, added, “With the introduction of Branch Repeater and Access Gateway as virtual appliances, we are bringing together the company's expertise in both networking and server/desktop virtualisation to deliver the industry's only complete end-to-end application networking virtualisation solution.”

In January Mainfreight overhauled its entire IT environment in China and Hong Kong with a virtualisation solution from Citrix which supports 160 users.
