Definition
Multi-cloud is the strategy whereby an organisation uses services from two or more different cloud providers (e.g. GCPGoogle Cloud Platform - Google's cloud platform, particularly strong in data and machine learning. + AzureMicrosoft's cloud platform - strong in the enterprise segment, especially where Office 365 and Active Directory are already in use.). The advantages include avoiding vendor lock-inWhen the cost of switching supplier is so high that you stay for reasons other than the product being the best one. Not all lock-in is deliberate, but all lock-in must be known., geographic redundancy and the ability to select best-in-class services. The disadvantages are increased complexity in operations, security and cost optimisation (FinOpsPractice framework for optimising and controlling cloud costs through collaboration between finance, development and operations.).
