Availability is one of the most important attributes of an online system, particularly those involving e-commerce, supply chain management, medical information, and financial transactions. For a continuous operating e-commerce site, maximizing uptime (i.e. availability) is one of the primary objectives. Uptime translates directly into transactions, which in turn are the source of revenue for the enterprise. SoHaR's team has developed an analysis methodology to improve website uptime, as well as network uptime. By means of business continuity planning and analysis we can direct the IT manager to the best way of increasing uptime. This methodology utilizes our state-of-the-art MEADEP tool to model the system architecture.
