451 Research's most recent Voice of the Enterprise: Digital Pulse survey provides insight into the decisions, challenges
The 451 Take
Organizations must balance the imperatives of business growth and IT modernization against the mundane reality of day-to-day operations that 'keep the lights on.' As IT organizations strive to address both transformation and maintenance objectives, workload placement decisions stand out as a particularly acute challenge. IT decision-makers are pursuing a variety of workload deployment approaches across increasingly heterogeneous off-premises and on-premises IT environments. The factors that determine the best execution venue for any individual workload are multi-faceted, including application characteristics, end-user profiles, data locality, security, performance requirements and sunk capital investments. The end result is a 'hybrid by default' IT environment in which on-premises IT environments (both legacy non-cloud and private cloud) continue to play a (diminished) role in enterprise IT estates.
All roads lead to
public cloud? Not so fast...
Growing proportions of organizations are shifting the bulk of their workload and application estates to cloud and (largely, but not exclusively) off-premises IT environments over the next two years. As our most recent VotE: Digital Pulse survey reveals, private cloud (both on-premises and hosted) and even colocation will continue on viable workload execution venues alongside public cloud IaaS/PaaS and SaaS environments.
The persistence of multiple execution venues spells continued opportunity for vendors and service providers with migration- and enablement-oriented offerings as deployment environment decisions shift in-line with the imperatives of the digital economy.
Mission-critical legacy apps: meet the new boss, (almost the) same as the old boss
Going forward, organizations are about evenly split on how to deal with legacy applications deemed to be mission-critical (i.e., those that cannot tolerate more than one hour of downtime without severe business consequences). A plurality of respondents (44%) pointed to 'modernization in place' as the way forward – keeping the workloads on-premises but updating the underlying application/infrastructure architecture.
