Migration Paths for Legacy Applications
Mario Angelic · 2012
This chapter focuses on the migration of applications from a legacy HA middleware to the SA Forum Application Interface Specification (AIS) middleware. The chapter first looks at the drivers for the migration, and then it continues with the review of the different aspects of system integration to define its levels with respect to the SA Forum specifications. The chapter presents the applicable approaches and techniques that can be used for the different services and most importantly for the Availability Management Framework (AMF). It discusses the efforts required to integrate applications with the availability management as well as with system management. The chapter point out also that the efforts needed to integrate an application with the system management are often at same level or even exceed the efforts required for the availability integration management.
