Multi-cloud Strategy is helpful because some cloud environments are better suited than others for a particular task; it also helps to prevent data loss and downtime due to the failure of some localized components in the cloud.
In addition, some cloud providers offer different tools or other specialized capabilities, such as machine learning, than their competitors; therefore the deployment of multi-cloud strategy in an organization provides the firm with several options to choose from.
Reasons why companies deploy multi-cloud strategy include the following
- Technical Goals: Most organizations with technical goals and broader business objectives deploy a multi-cloud strategy. This can include the use of more price competitive cloud services, or taking advantage of the speed, features, and capacity offered by other cloud providers in a given geographical area.
- Data Sovereignty: Some organizations deploy multi-cloud strategy due to data sovereignty reasons; some laws and regulations require enterprise data to be domiciled in a particular location. With multi-cloud computing, organizations can meet those regulations because they are free to choose from multiple IaaS providers' data center regions. The flexibility in where the cloud resides enables organizations also to locate resources closer to the end user to increase optimal performance.
- Avoid Vendor Lock-In: Another reason why most organizations deploy the use of multi-cloud is to avoid vendor lock-in. This is because a multi-cloud strategy provides organizations with options to change cloud providers as needed. Deployment teams can build apps that work across providers. This approach makes it easier to transfer data between cloud service providers when pricing and different features make a different provider more appealing.
- Freedom to seamlessly shift transaction: The fact remains that every cloud provider has its weaknesses and strengths. And many organizations that deploy the multi-cloud strategy take advantage of these multiple providers to shift transactions from one provider to another as needed seamlessly.
- Reduces DDoS attack: As the cloud continues to grow, so has the likelihood of DDoS attacks increased. However, with a well crafted multi-cloud strategy, organizations can reduce the effects of DDoS attacks by providing a level of resiliency which is not available with a single provider. The IT teams can transfer data from a provider that suffers DDoS attack to another within the cloud environment.
- Improves reliability: A multi-cloud strategy helps to improve reliability. For instance, when the primary cloud has failover issues, a passive cloud could seamlessly serve as an option for e-commerce transactions, and once the primary cloud is restored to function normally, all operations can be reverted automatically.
Finally, the benefits of multi-cloud strategy to the enterprise cannot be overemphasized. From reducing DDoS attacks, providing freedom to shift transaction and improving reliability seamlessly, the multi-cloud strategy has remained instrumental to the establishment and maintenance of competitive advantage. However, despite all these benefits; there are some drawbacks associated with a multi-cloud strategy. For instance, the use of multi-cloud strategy demands that the IT staff of an organization have knowledge about multiple cloud platforms and providers. In addition, application management in multi-cloud can be quite challenging as information moves from one cloud platform to another.
