predictability, contractual flexibility and the freedom to adapt must be core criteria when assessing any multi-cloud ecosystem and not just technical performance alone.
What makes this an issue for CISOs and not just a business concern?
CISOs are there to ensure the survivability and resilience of the business. Their role requires managing a wider risk profile and supporting the CFO in ensuring the organisation has a plan for commercial risks and threats to operations.
Security isn’ t just about preventing attacks – it is about making sure the organisation has visibility to a wide range of threats that may impact operations.
Building resilience into multi-cloud strategies
Given the range of risks outlined above, it’ s clear that CISOs must take a far more strategic and forward-looking approach when evaluating their organisation’ s multicloud systems. This isn’ t just about performance or uptime. It’ s about preparing for disruption, especially the kind that arrives without warning.
What happens, for example, if a cloud provider is suddenly subjected to new government tariffs, regulatory scrutiny, or even outright bans? These may seem like distant scenarios, but the geopolitics of technology in today’ s world are moving quickly. Cloud infrastructure is increasingly a national security concern, and providers can quickly find themselves caught in the crossfire. For CISOs, that means planning for exits even before a contract is signed.
The principle is simple: never get so entrenched in a provider that leaving becomes impossible. Or, to borrow from the 1995 film Heat,“ Don’ t let yourself get attached to anything you are not willing to walk out on in 30 seconds flat if you feel the heat around the corner.” It may be a Hollywood line, but the underlying advice holds, particularly when vendor dependencies threaten organisational agility.
The consistency conundrum
However, beyond contracts and costs, there is the more technical( and equally critical) challenge of maintaining security while ensuring efficient data synchronisation across clouds. This is where CISOs must make decisions grounded in the business’ s core objectives and risk tolerance.
At the heart of this decision lies the trade-off between strong consistency and eventual consistency. Strong consistency ensures that data is updated immediately and is accessible in real
