Fallacy: Cloud Storage Is Inexpensive
A common misconception is that cloud storage is more economical than traditional ways of storing data. When agencies start retroactively preparing all their data for migration and storage in the cloud, they can run into higher-than-expected costs and experience sticker shock. It also makes it harder for agencies to budget as they try to keep pace with growing storage demands. By tiering data, agencies can significantly reduce costs, paying more for data that must be accessed daily and paying less for data that can be stored away for regulatory or compliance purposes. This approach can cut costs, but it comes with the challenge of managing data across multiple clouds.

Fact: Vendor Lock-In Can Be Avoided
Being tied to the same vendor once all systems have moved to the cloud is another concern, especially if the vendor’s prices increase. Agencies that implement multicloud solutions can avoid dependency on one specific vendor. By using several cloud platforms, agencies have the flexibility to move between service providers. However, a multicloud architecture must be interoperable to avoid problems. PwC recommends using decoupled microservices with containers. Decoupling development and deployment will ensure continuous integration, while the use of containers will ensure interoperability.
