The fast growth in cloud adoption, as well as the availability of a wide range of robust cloud platforms, gives businesses the option to use multiple cloud vendors. Based on a 2018 global survey of 727 cloud technology decision-makers, Forrester Consulting noted that 86 percent of respondents use a multicloud strategy. The report also found that 60% of enterprises are moving, or have already moved, mission-critical applications to the public cloud.2
Connectivity: The data connectivity requirement for multicloud hybrid IT architecture becomes more complex because integration needs to happen from on-premises systems to multiple cloud environments, with each of them having their unique access, security, and data model specifications. In addition, each data extract process impacts the source production system.
The data integration solution for a multicloud architecture should support a broad set of cloud services across multiple clouds to give the flexibility to expand to new cloud solutions as needs arise. Cloud vendors’ own integration offerings cannot provide the diverse connectivity that an independent software product can. The ability to use a single, independent software offering for multiple cloud environments can minimize licensing costs and reduce the learning curve to integrate to additional cloud targets.
Monitoring: Pipeline monitoring becomes imperative when the architecture is more complex with more cloud endpoints. Having a single integration solution that can deliver timely data to all required cloud services can also mean that a single monitoring application can give an overview of all cloud integration pipelines. Therefore, a solution that has built-in and continuous integration monitoring capabilities can streamline managing a complex, multicloud IT environment.
Impact on Data Sources and Architecture Complexity: Another best practice for multicloud hybrid integration is to minimize source impact by using a single application to extract data from the source system, and then deliver the data to multiple cloud targets without having to set up separate integration applications. This capability not only reduces integration architecture complexity, but also minimizes the impact on the source systems that are in production and cannot be overburdened with multiple extracts.
Core Requirements for Hybrid Cloud: Additionally, the requirements mentioned for cloud migration, building new systems in the cloud, and cloud analytics also apply to a use case where there are multiple cloud targets. Access to real-time data from diverse sources, delivered in a consumable format, are still requirements for any operational use case in a multicloud architecture set up.
