    Hi,

    Nicely done blog and quite informative. Just wanted to highlight one point.
    It is mentioned that with ITS, load balancing is not possible. SAP ITS is quite scalable and offers multiple installation options for scalability and performance optimization. These include:

    1. Load balancing through external products (HTTP routers, Web switches) over multiple Web servers
    2. Single host and dual host installation, with option for installing a firewall. Take a look at http://help.sap.com/saphelp_47x200/helpdata/en/87/4d5739d335a85ee10000000a114084/frameset.htm for more details.
    3. Multiple (virtual) SAP ITS instances on a single host
    4. A WGate can control multiple AGates
    5. An AGate can be addressed by multiple WGates
    6. Can set the dimensions (number of workthreads and memory size) of each AGate for the expected user load
    7. An AGate can log on to the SAP system using load distribution (logon groups)
    8. The AGate can reduce the volume of data transferred to the Web browser (compression with gzip)

    The option to choose depends on organization’s needs.

  2. Thanks for the info, some pointers

    Personalization:

    Its possible to bring about a different look and feel by modifying the css files .If integrated with the EP , the theme editor of EP accomodates style changes for ITS too

    Support to Business Graphics:

    ITS also uses IGS for displaying business graphics such as networks and bar charts

    You could also include the differences in the support for authentication mechanisms , WAS supports JAAS but ITS uses PAS etc

    Also how much of this changes with the Integrated ITS(ITS on WAS) also needs to be investigated.
