Over the last 18 months, Acme has experienced significant growth in its online purchasing operations. Statistics collected over the eighteen-month period indicated a 33% increase in web site visitor traffic. The increased load is driven throughout the entire system thus affecting every part of Acme’s web environment. Database transactions have experienced similar growth creating scaling issues equal to that of the front-end web servers.

To date, Acme has employed traditional scaling methods in an attempt to keep pace with increasing demands. These methods include the purchase and deployment of larger enterprise-class RISC processor servers, thereby scaling vertically. The concept of vertical scaling is readily apparent in the database back-end element of their architecture. Acme currently employs 2 Sun Fire 6800 servers, ea

A detailed and well-conceived project management plan has been developed. The project is well organized and will be capable of providing the leadership and technical resources to complete the Linux migration. Full integration of project milestones in the work schedules and coordination with the proper planning has been established. For quality assurance purposes the further development of processes (i.e. daily regression tests) and the integration of tools into an overall capability (i.e. regression testing integrated with bug tracking) have been implemented.

Included in the attached project plan will be the task responsibility matrix. This will detail the tasks assigned to each member or group of the project team. Acme’s management team has a number of responsibilities. Determining the project need and scope comes first, because this will dictate the crucial sponsorship and budgetary resources.

Phase three is the design phase. Drawing from the data collected in the analysis phase, a detailed design document will be produced. The design document is an essential component of the project, as it will provide the blueprints for execution during the process. Once the architectural resources are identified and secured, the team will draft a preliminary document and distribute this to key stakeholders for input. A final detailed version of the design document will be created to include any feedback received and confirmation that the design aligns with Acme’s long-term business strategy.

The project manager will be responsible for developing an estimated budget. The estimated budget will determine the cost of each task. The project budget represents the management’s long-term to short-term plans for the project. The budget also contains the management goals and resources to achieve these goals within the defined timetable.

Phase two consists of a detailed analysis of Acme’s current environment, processes and architecture. Detailed examinations of three critical areas, hardware, software and support, reveal several elements to be considered in the design phase. The first objective is the replacement of Acme’s enterprise-class servers with low-cost PC-class hardware. The analysis of this area consists of identifying and evaluating the applications, their dependencies and the load characteristics currently supported. Acme’s environment contains components that are common to most front-end web server environments, thereby lowering the level of effort required to seamlessly migrate the architecture.
