Incorporating Systems of Record as Part of a Mobile and DevOps Strategy: Leveraging Agile to Bring in Legacy
This IDC study discusses current views about mainframe inclusion as part of DevOps and the consequences of a lack of visibility and coordination between legacy systems and "modern" development including mobile systems of engagement. The exploding demand and velocity of change resulting from the need for "multimodal" or cross-platform software deployments is becoming business critical to remain competitive for many organizations. As companies seek to evolve digital innovation and business-critical mobile applications, coordination with, and leverage of, existing mainframe, back-end systems of record (SoRs) is a key, necessary focus increasingly. Interactions with IDC clients indicate that around 70% of enterprise businesses continue to run organizational and other data on the mainframe. Taking advantage of iterative, agile approaches to deliver applications can add incremental business value quickly and efficiently, speeding delivery while helping cut costs. This applies equally to the context of coordinating with existing SoR mainframe-based applications. IDC defines DevOps as an agile, end-to-end approach from software inception through to deployment (and beyond), which can both enable and sustain digital innovation and transformation. And we see companies looking to RESTful APIs and modern tools to open up core mainframe applications to mobile devices and development without the effort, redundancies, risks, and costs of typical rehosting. Establishing strong practices and organizational approaches complemented by automated strategies to establish integration via RESTful APIs (as compared with rehosting) along with organizational and process change is becoming key increasingly. The intent of this study is to help explain how companies are shifting from the downsides and challenges of unengaged approaches to SoR as part of DevOps and provide additional context through insight into some strategies for implementation to evolve broader, more encompassing agile DevOps strategies."There is increasing demand for DevOps strategies that include systems of record and incorporate successful approaches to include back-end, legacy systems and applications on the mainframe as part of digital transformation," said Melinda Ballou, research director for IDC's Agile Application Life-Cycle Management, Quality and Portfolio Strategies service. "Bridging the gap between modern development on mobile and other platforms and existing systems is becoming a focus for DevOps strategies increasingly. Too frequently, schisms exist between development groups and a lack of proactive approaches to encompass existing systems as part of DevOps can straightjacket organizations that rely on back-end applications and must coordinate them with systems of engagement on the front end. We expect companies to incorporate broader approaches increasingly to flexibly address dynamic, changing competitive needs while leveraging legacy environments."
