It goes without saying that some legacy applications, such as those with basic two-tier architecture and minimal integration points with other systems, are relatively simple to re-platform without sacrificing performance or functionality. On the other hand, other systems, such as highly distributed systems or those with low latency or high-volume demands, require a far more deliberate approach to re-platforming. In addition, not all legacy applications are good candidates for migration. Cloud, Platform as a Service (PaaS), and Software as a Service (SaaS) come with their own challenges. In this guide, the executive IT professional will get an itemized benefit of re-architecting applications for the cloud in context of complex and non-complex cloud considerations; a recent set of best-practices in relationship to the most common challenges; and actionable next steps for developing a re-platforming strategy. |
