Key concepts of enterprise architecture
When undertaking a cloud migration project, an IT Strategy needs to be clearly defined – these include the procedures, processes, and cultural ideals of the team (Hayles, 2013). This IT strategy is the starting block for an organization to shift to the cloud and can predict the level of success while minimizing risk. A comprehensive project portfolio evaluation would scrutinize the current state architecture, gather requirements for the future state architecture, design new IT processes, outline the steps to reach all milestones, and define a reliable lifecycle to manage. This process can take months and involve the collaboration of all departments in the organization.
Following the completion and distribution of the IT strategy, metrics need to be outlined of how to define success criteria. This leads to monitoring the migration and cloud developments which require IT performance management processes in place that track against these metrics (Hayles, 2013). Altogether, these processes will assist how IT can control cloud resources by frequently extracting expense, utilization, access logs, and security data. Leadership is kept aware of these values and any anomalies must be handled promptly to minimize risk. Within a properly designed system, the governance body is always aware of on-going cloud updates.
Logical Architecture is the third and last concept and defines how IT professionals mimic the same logical architecture from on-premise systems onto the cloud resources (Hayles, 2013). If these concepts can be mimicked on the cloud to satisfy business requirements, IT can ensure business continuity. This allows for an initial point of entry and sets the groundwork for further development. This is critical to set the stage to expand into additional offerings to improve IT capabilities and streamline business processes.
