Intalio|Cloud » Intalio|Cloud On-Premises

Business Model

With the On-Premises deployment option, customers deploy the Intalio|Cloud software stack on top of their own hardware, connected to their private network, and installed into their own data-center. Furthermore, customers are responsible for performing all required software upgrades, within 3 calendar months following the release of a new product version.

Architecture

The Intalio|Cloud platform must be able to serve a very large number of accounts (hundreds of thousands), for both small (no more than 3) and large (millions) numbers of users, in a multi-tenant environment and in a perfectly elastic manner. For this purpose, it features a unique architecture that supports both up and down scalability. With this architecture, small accounts which master database server can fit onto a single blade are served by a Virtual Machine (VM) deployed on top of an hypervisor (VMWare or Xen), while larger accounts that require more powerful hardware for their master database server are deployed on top of a virtual Symmetric Multiprocessing (SMP) cluster powered by ScaleMP's vSMP Foundation.

Small Account Configuration
A small account is defined as an account which master database server can fit onto a single blade server. A typical blade is made of 2 Quad Core Intel Xeon X5570 2.93GHz (8 cores total) CPUs and 144GB (18 x 8GB) 1333MHz PC3-10600 DDR3 Registered DIMMs. Since many enterprise applications require many more database Read operations than Write operations (with a 10 to 1 ratio typically), multiple slave database servers can be dedicated to Read operations, while the master database server is used for Write operations only. Furthermore, a typical Web-based application requires many more application servers than database servers (with a 4 to 1 ratio typically). As a result, a "small account" might use quite a few blade servers (50 or more typically), before having to be upgraded to the unlikely "large account" configuration.

Large Account Configuration
A large account is defined as an account which master database server cannot fit onto a single blade server. The master database server required by such accounts is served by up to 16 blade servers (32 CPUs, 128 CPU Cores, 2.3TB of DRAM) configured as a virtual SMP cluster using ScaleMP's custom firmware and the InfiniBand interconnect. All blade servers used by the Intalio|Cloud Appliance support both configuration through dual boot, and the migration of accounts from one configuration to the other can be achieved in a few minutes.
