While some companies are still pondering on the right cloud adoption strategy, several businesses have already started taking the next step. These businesses are now looking into a multi-cloud strategy in order to further improve on the success of their current cloud initiatives. But what exactly are the advantages of a multi-cloud strategy?
The time-honored rule of not putting your eggs in one basket applies here. In the cloud discussion, having total dependence on a single cloud can put your business at risk.
For example, subscribing to a single cloud service provider (CSP) can make you susceptible to the consequences of vendor lock-in. What if your provider decides to increase its prices? What if you’re no longer happy with their services or have found a better provider? Or worse, what if your CSP goes bankrupt? By spreading your IT assets across multiple clouds, you can mitigate these types of risk.
We can also look at this from a high availability and disaster recovery / business continuity perspective. Because a multi-cloud strategy can mean either making IT assets redundant across multiple data centers and cloud infrastructures (with separate networks and geographical locations to boot) or splitting sets of servers, applications, and data between them, you can increase high availability and reduce the chances or periods of downtimes.
Take advantage of best-of-breed offerings
With more enterprises pouring their investments into cloud adoption, the cloud industry has never been more highly competitive. In order to attract customers, CSPs are investing heavily on key differentiators. As a customer looking to implement a multi-cloud strategy, that’s excellent news.
You can pick cloud providers on the basis of their SLAs, APIs, technical support, security compliance capabilities, or a range of other specialized technologies/features, and then deploy your IT assets where they’re most suitable.
For example, you can entrust your highly sensitive assets (or those covered by PCI DSS, HIPAA, GLBA, SOX, or other regulations) with a CSP offering superior compliance capabilities, while deploying your assets that require environments with better integration and extensibility capabilities with a CSP offering better APIs.
Meet needs of geographically dispersed teams
Enterprises that have business units operating in different geographical locations will want to consider adopting a multi-cloud strategy. Business units operating far from their CSP’s data center(s) will experience slow response times due to latency. This can impact overall performance of those business units and cause delays.
The only way to address this problem is either by choosing a CSP that also has data centers near those business units or by subscribing to a CSP in those localities.
Best fit for specific applications and business needs
In the previous sections, we focused on a multi-cloud strategy involving different CSPs. A multi-cloud strategy doesn’t have to be that way all the time. It could also mean using a combination of public, private, and hybrid clouds.
Each of these cloud deployment models have their own advantages. For example, a public cloud offers the most cost-effective way of achieving scalability, while a private cloud is the only way you can achieve close integration between your legacy IT assets and your cloud infrastructure.
