Fallacy: Cloud storage is cheap
A common misconception is that cloud storage is cheaper than traditional ways of storing data. When agencies start retroactively preparing all of their data for migration and cloud storage, they may face higher-than-expected costs. Many agencies experience a shock after migrating data. It also makes it more difficult for agencies to budget as they try to keep pace with growing storage demands. By prioritizing data, agencies can significantly reduce costs, paying more for data that must be accessed on a daily basis and paying less for data that may be stored for regulatory or compliance purposes. But while data tiering can reduce costs, managing data across multiple clouds is a challenge with this approach.

Reality: Vendor lock-in can be avoided
Another big concern is being tied to the same provider once all systems have moved to the cloud, especially if the provider’s prices increase. Agencies implementing a multi-cloud solution can avoid lock-in to a specific vendor. By using multiple 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 using containers will ensure interoperability.
Fallacy: The cloud is fundamentally insecure
Many organizations see security as a primary challenge to cloud adoption. a recent StateTech The Twitter survey reflected this view: 44 percent cited cybersecurity as the top hurdle for IT decision makers. In reality, cloud service providers, including Microsoft, Amazon Y Google — invest more in cloud security than most agencies. In fact, moving to the cloud can improve security. Agencies can start small by moving some workloads to the cloud and evaluating the results. Third-party assurance reports can also give agencies insight into how cloud providers handle their data. Agencies can also choose a hybrid approach, where some data is stored in the public cloud while more sensitive data remains in private data centers.

Once agencies are comfortable moving their workloads to the cloud safely, they can fully transition from a hybrid cloud model to the public cloud. To avoid breaches, agencies must recognize that public cloud providers are not responsible for all aspects of cloud security. Agencies must manage security controls for their applications and user accounts.

Reality: The cloud is not a one-size-fits-all solution
There is no single, comprehensive cloud model. Every cloud implementation looks different for every organization because every organization has different needs. Agencies can choose from a variety of models, such as software as a service for cloud-hosted applications; Infrastructure as a service for cloud-based data storage, servers and networks; o Platform as a Service for integrated cloud-based infrastructure, among others. Several factors can influence which cloud model an agency chooses, including the size of the agency, existing legacy systems, budget constraints, and whether you want to migrate your data gradually or all at once. Ultimately, the model an agency decides to implement must be suitable for specific applications or use cases.
