Many enterprises are planning their private cloud environment construction. Many IT providers already announce new products for private cloud. I firmly believe that IBM PureSystems is one of the most optimized systems for private cloud. It has a function of resource pools of server, storage, and network. I think for private cloud acceleration, IT providers should provide follow-up functions in migrating to virtualized environments, which are currently working on the non-virtualized environment.
Three use cases of appliances with private cloud
Currently, there are so many use cases of non-virtualized appliance products with private cloud.
Use case 2: Private cloud work with software as a service (SaaS)
Use case 3: Private cloud third party vendor infrastructure as a service (IaaS) and platform as a service (PaaS)
Consideration for accelerating private cloud
Examples of non-virtualized appliance products:
･ Wide Area Network (WAN) accelerator
WAN accelerator has a function of data compress, data caching, and control network wideband and so on for accelerating WAN communication speed.
･ Secure Socket Layer (SSL) accelerator
SSL accelerator is efficient for speed of SSL networking.
･ Network dispatcher
Recently, network dispatcher has so many functions, including web session control with multi web servers. Many enterprises use network dispatcher with the redundant configuration for availability and scalability.
For security, we need firewall appliances. Firewall has the function of domain name system, network address transfer and port control and so on.
Currently, many enterprises use above non-virtualized appliances. For accelerating private cloud, IT vendors should provide these functions below:
Option 1. Provide service as a virtual appliance.
We can improve speed and expansion of the system. Furthermore, we can escape from physical restrictions. As a result, private cloud is accelerated and improved in its portability.
