Is It Time To Diversify Your Cloud?

Reduce your cloud costs and create new opportunities with a multi-cloud strategy

Amazon Web Services (AWS), Azure, and Google Cloud Platform (GCP) are the public cloud market leaders, but how do you determine which of them best supports the specific needs of your enterprise? For a majority of enterprises, and for the foreseeable future, it’s going to be a multiple answer question.

Gartner predicts that “…A multicloud strategy will become the common strategy for 70% of enterprises by 2019.”

Considering that multicloud accounts for less than 10% of enterprises today (according to the same report), that would mark a significant increase of adoption in a very short time, even by fast-paced technology standards. However, according to a recent study by Microsoft and 451 Research, nearly a third of organizations already work with four or more cloud vendors.

So, the evidence is there. The experts are predicting it. How did we get here? It starts with one of the oldest myths about cloud computing: “We need one cloud strategy or vendor.” That’s not necessarily true.

On the one hand, it can be argued that working with one vendor simplifies your work, since:

  • Your IT team ought not to be platform diverse
  • Middleware is highly cohesive
  • The decision-making process of what services to use is simpler, since the service spectrum is defined by your single, chosen provider
  • It’s easy and comfortable for you, but especially, for your vendor

On the other hand though, your cloud attachment exposes you to a variety of issues, such as:

  • Cloud data center outages
  • Bandwidth problems
  • Vendor lock-in
  • Significantly diminished power to successfully negotiate pricing and/or business disagreements
  • Opportunity cost


But as always, the most obvious point for not sticking with a single vendor for ANY service, is that the same service type from an alternative vendor might better suit your case – and cost less.

Of course, you should not diversify for diversity’s sake. If your strategy isn’t thought through, dealing with a bunch of different vendors could cause more headaches than it relieves. The same holds true for going to the cloud for cloud’s sake.

So, how do you know whether it’s time to diversify your cloud strategy? This is actually the simplest part of the whole process, as it essentially comes down to two main reasons:

  • Your current cloud costs are higher than you planned/wanted
  • New requirements demand a new set of services, that may or may not offered by your current provider

For example, one of our clients underwent a 3+ year migration to AWS from on-premises. Five years later, they’re still enjoying a close relationship with the cloud provider and satisfied with the variety of services offered. Nevertheless, unexpected high bills and new requirements challenged the status quo.

New requirements dictated an Identity Cloud solution, as well as an API management platform. At the time, specific requirements to the solutions weren’t satisfied by AWS offerings. Luckily, Azure seemed to offer exactly what they needed.

The lesson? Your specific, evolving requirements, and business environment will drive your need for diversity.

A few years later, that same client once again reevaluated their needs, and it was clear that Azure Active Directory (AD) no longer supported their case, while Azure API management still served them well. So, they dropped Azure AD, but kept another service in Azure.

Already exposed to multicloud, the customer sought advice on unexpected high costs in AWS. We analyzed the case and rvelez@eastbanctech.com or 202-295-3015.
