Portal Design Approach
Your high-level portal design communicates the architecture of the system and provides the basis for the low-level design of your solution. Further, the high-level design needs to describe a logical architecture that meets the business and technical needs that you previously established. The logical architecture is broken down according to the various applications that comprise the system as a whole and the way in which users interact with it. In general, the logical architecture includes Portal Server Secure Remote Access (SRA) , high availability, security (including Access Manager, and Directory Server architectural components. See “Logical Portal Architecture” on page 81 for more information.
The high- and low-level designs also need to account for any factors beyond the control of the portal, including your network, hardware failures, and improper channel design.
Once developed, the high-level design leads toward the creation of the low-level design. The low-level design specifies such items as the physical architecture, network infrastucture, Portal Desktop channel and container design and the actual hardware and software components. Once you have completed the high- and low-level designs, you can begin a trial deployment for testing within your organization.
Overview of High-Level Portal Design
The high-level design is your first iteration of an architecture approach to support both the business and technical requirements. The high-level design addresses questions such as:
•Does the proposed architecture support both the business and technical requirements?
•Can any modifications strengthen this design?
•Are there alternative architectures that might accomplish this?
•What is the physical layout of the system?
•What is the mapping of various components and connectivity?
•What is the logical definition describing the different categories of users and the systems and applications users have access to?
•Does the design account for adding more hardware to the system as required by the increase in web traffic over time?
