They also help organizations determine which cloud providers are underperforming, ultimately saving money while organizations make the client experience better. Combined Policy, Management, and Visibility Everything described in this book works only if your organization combines policy, management, and visibility across all of your cloud providers. This is absolutely necessary, even though each cloud pro‐ vider in a multicloud architecture has different capabilities and dif‐ ferent provisioning and management platforms. The only way for a multicloud solution to be efficient and effectively managed is if everything is viewed through the same platform on your end. Using a unified platform that is cloud-provider aware can make it easier to deploy, enforce policies, and manage and monitor all providers through the same "pane of glass." This also allows organizations to take advantage of efficiencies of scale. Organizations can quickly deploy to new datacenters, patch systems across all cloud providers simultaneously, and enforce new security policies, such as new DDoS protection rules. A centralized management and monitoring framework provides end-to-end visi‐ bility and gives organizations an early warning when systems are beginning to fail. Complexity Requires Granularity of Policies Although you can build out management and monitoring tools after the multicloud infrastructure is built, system policies should be deci‐ ded prior to deployment. It is important to deploy compliant infra‐ structure from the start, whether these policies are related to security, information retention, or regulations such as the Payment Card Industry Data Security Standards (PCI DSS) or the Health Insurance Portability and Accountability Act (HIPAA). Trying to retroactively make a non-policy compliant facility or sys‐ tem compliant after deployment is painful and can lead to gaps that violate the policy. Policies also need to be granular to properly cover a multicloud deployment, especially if that multicloud deployment is spread across multiple countries. Different countries have different regula‐ tory frameworks and might require various policies to remain com‐ Combined Policy, Management, and Visibility | 49
