A Forrester report from January 2018, “The State Of Cloud Migration, Portability, And Interoperability, Q4 2017,” by Lauren E. Nelson and Charles Betz, grades the maturation of various approaches to assess available tools, ease of completion, and the reality of solving these problems for enterprise cloud adoptions. Migration gets a solid “B” grade, indicating some adoption as well as a largely manual or resource-intensive process.
As Nelson and Betz point out, “Migration isn’t easy. Technology managers target specific application characteristics that are favorable to cloud while also leveraging a combination of lift-and-shift and redesign characteristics.” Cloud migration shifts the burden of high availability and performance from infrastructure to the application. Apps not built for the cloud often suffer from performance issues due to their monolithic architecture, which is unfit for horizontal scaling. Partial or full redesign is usually necessary, but it’s labor-intensive and time consuming.
While the Forrester report’s discussion of the lift-and-shift approach to migration offers a good overarching view, it’s important to break it down into more detail.
It’s also not necessarily a short-term fix. It’s a way to stabilize an out-of-date business that allows it to grow into a more cloud-centric model, and also an ideal application for some clients who are already running a cloud-ready architecture. However, it can be a short-term fix if an enterprise chooses, because it can act as a beneficial first step to a less complicated – and therefore less risky – source code rewrite.
Mainframe has been and is currently seen as a strategic initiative – yet the lift-and-shift method has not been utilized as much because many enterprises are unaware of the types of solutions out there. Yet they exist – and TmaxSoft’s OpenFrame offers a complete mainframe rehosting solution that lets enterprises take (lift) existing mainframe assets and move (shift) them to the public or private cloud, quickly and with minimal risk. This helps a business save on costly mainframe contracts and more effectively leverage critical data, while gaining a more flexible and transparent environment.
Additionally, while the report refers to rehosting within the context of cloud – and that certainly is a popular option – it’s important to note rehosting can also be done on-premise, from a mainframe to a captive datacenter. With OpenFrame, it doesn’t matter whether it’s cloud or on-premise—it’s destination agnostic.
