Cloud computing — storing data and accessing apps via the Internet — has been widely adopted by businesses across industry and size. Like many technological advances, though, new derivatives continue to emerge — including so-called multicloud computing.
Under this approach, companies don’t rely on a single cloud service; rather, they distribute their data and computing needs among several providers. Popular options include Amazon Web Services (AWS), Google Cloud Platform and Microsoft Azure.
The strategy offers various advantages. For example, like any cloud computing arrangement, it provides scalability. As your needs expand or drop, you can readily adjust your storage capabilities to keep a lid on costs.
Multicloud computing also is a way to hedge your bets. Every cloud provider has downtime at some point but, if you use multiple clouds, you can switch critical workloads and applications to a cloud that’s up and running. And it helps you avoid “vendor lock-in,” or getting restricted to a single provider’s infrastructure, add-on services and pricing models.
Improved performance is another factor. Using several providers based relatively close to you geographically means fewer “network hops” between servers. This reduces latency (the delay between a user’s request and the provider’s response), jitter, packet loss and other disruptions.
Many businesses prefer the “a la carte” nature of multicloud computing. Different providers may have different features that you need to meet your technical or business requirements. For instance, you might choose a pricier but more secure cloud for applications with sensitive data and a cheaper alternative for less sensitive data. Similarly, a business that relies heavily on Windows might use Azure for internal operations but tap AWS for its website and Google Cloud for machine learning.
Some companies find themselves engaging in multicloud computing without ever deciding to do so. Unintentional multiclouds can result from “shadow IT,” whereby different departments or business units start using public clouds on their own accord and then one day turn to IT for help.
Whether multicloud computing develops from shadow IT or a conscious strategic decision, it comes with potential pitfalls. Managing multiple clouds can prove complex. You can use integrated suites of software known as “cloud management platforms” to administer multiple clouds. But these platforms tend to take a “least common denominator” approach, treating multiple clouds as a single cloud by focusing on storage, network and computing functions. As a result, you may find it difficult to leverage each cloud provider’s distinctively useful features.
Last but certainly not least, you must consider the total cost of ownership of any multicloud strategy. Although the availability of alternative providers may increase your bargaining power, the cost of paying several vendors can go beyond the upfront prices and monthly fees. You may also incur additional fees for items such as licensing and integration. We can help you perform a cost-benefit analysis of any multicloud solution you’re considering.

For several years now, cloud computing has been touted as the perfect way for companies large and small to meet their software and data storage needs. But, when it comes to choosing and deploying a solution, one size doesn’t fit all.
Many businesses have found it difficult to fully commit to the cloud for a variety of reasons — including complexity of choices and security concerns. If your company has struggled to make a decision in this area, a hybrid cloud might provide the answer.
Public vs. private
The “cloud” in cloud computing is generally categorized as public or private. A public cloud — such as Amazon Web Services, Google Cloud or Microsoft Azure — is shared by many users. Private clouds, meanwhile, are created for and restricted to one business or individual.
Not surprisingly, public clouds generally are considered less secure than private ones. Public clouds also require Internet access to use whatever is stored on them. A private cloud may be accessible via a company’s local network.
Hybrid computing, as the name suggests, combines public and private clouds. The clouds remain separate and distinct, but data and applications can be shared between them. This approach offers several potential advantages, including:
Scalability. For less sensitive data, public clouds give businesses access to enormous storage capabilities. As your needs expand or shrink — whether temporarily or for the long term — you can easily adjust the size of a public cloud without incurring significant costs for additional on-site or remote private servers.
Security. When it comes to more sensitive data, you can use a private cloud to avoid the vulnerabilities associated with publicly available options. For even greater security, procure multiple private clouds — this way, if one is breached, your company won’t lose access or suffer damage to all of its data.
Accessibility. Public clouds generally are easier for remote workers to access than private clouds. So, your business could use these for productivity-related apps while confidential data is stored on a private cloud.
Risks and costs
Using a blended computer infrastructure like this isn’t without risks and costs. For example, it requires more sophisticated technological expertise to manage and support compared to a straight public cloud approach. You’ll likely have to invest more dollars in procuring multiple public and private cloud solutions, as well as in the IT talent to maintain and support the infrastructure.
Overall, though, many businesses that have been reluctant to solely rely on either a public or private cloud may find that hybrid cloud computing brings the best of both worlds. Our firm can help you assess the financial considerations involved. Call us today at 205-345-9898.
