SAP EP-How to make Enterprise Portal highly available.
High availability of portals
Before portal implementation starts, its planning should be done. The most important part of planning is portal technical infrastructure design. The technical infrastructure should be such that users get the following benefits from it.
Robustness
Optimized performance
Scalibility – how many concurrent users can use the portal drawing good performance from it.
Security.
In order to achieve the above objectives, we need to know what are the factors which affect high availability of portal.
We draw various benefits if the portal implemented has the above features in it.
reduced unplanned downtimes, reduced unplanned maintenance effort, and ultimately increased customer satisfaction.
Essentials of Good Portal Infrastructure Design
A good portal should have following features :
Should serve the customers with proper functionality and that too with quick responses.
If the population using the portal increases or the functionality being served by the portal increases, it should be able to handle it. So it should be scalable.
Machines on which portal installations (single or cluster) is done whould be in good condition and shape so that good performance is derived from them.
Should be highly available, minimum downtimes. Must have only planned downtimes ideally.
Portal should be secure enough as it is a platform for business critical data of the organization.
In order to get a high-end and highly available portal application, cost may increase. A proper tradeoff should be done between creating a highly available portal application and the total cost of ownership.
Portal System Landscape Design
Generally there are 4 systems which comprise of the portal system landscape : sandbox, development,
quality, and production systems.
Technical infrastructure for the all the systems has to be designed.
For each system, we have to find out how many host machines will be needed. Number of host machines depends upon the number of software units. Each software unit in turn will have specific requirements from which we will come to know about the server requirements. Once the software units are decided, next step to choose a host machine to install a software unit. Then we need out how much load will be imposed on the host machine after installing the software unit. Depending upon load, the sizing of the machine should be done ie. number of processors, gigabytes of RAM, disk size etc
