Despite the many benefits that multi-cloud can bring to a business, this approach isn’t without its challenges, especially from an identity management perspective. Potential problems include:
More Clouds, More Complexity
The decision to expand from a single provider naturally brings increased complexity. It’s hard enough to manage access to applications and environments safely and consistently when everything is running on a single cloud platform. Doing it across two or three providers adds to the challenge.
Multiple Specialist Skilled Teams Needed
Because multi-cloud deployments are more complex, you’ll need a highly skilled team to design, implement, and manage them. Additionally, using multiple cloud vendors requires using duplicate teams with specialist skills across these vendors. Given the ongoing IT skills shortage, hiring and retaining experts with the required level of cloud security expertise can be a tough challenge.
Cutting costs is a big reason why many companies choose to move to the cloud in the first place—but without careful planning and management, multi-cloud can end up being a costly endeavor. Flexible charging models can make it difficult to predict costs, especially if you don’t have a good handle on which users will be accessing which systems and resources.
Increased Security Concerns
It’s much more difficult to protect data and enforce access control policies across a multi-cloud architecture, which opens up a wider range of security vulnerabilities. Without a rigorous, centralized approach to identity management, governance and security, organizations open themselves up to a higher risk of data protection issues and security breaches.
