Picking and choosing: Atos give an overview of multi-cloud storage

As multi-cloud undoubtedly looks to be the prevailing strategy when it comes to cloud-based digital transformation, many firms are taking the same approach when it comes to storage. We speak to Atos to determine what multi-cloud storage is and how enterprises are employing it.

As digital transformation and migrations to cloud-centric IT strategies continue to persist as major imperatives of enterprise organisations, more and more are we hearing that the prevailing overall strategy has been the implementation of hybrid or multi-cloud architectures. While the public cloud heavy hitters of AWS and Microsoft might be keen to tell you that the future involves going all-in on public cloud, enterprises have found such a strategy to be all too limiting when it comes to fulfilling the diverse IT requirements modern businesses demand.

However, adopting multi-cloud can be a perplexing mission. It's difficult enough to manage the pure migration-based headaches that come about when moving from legacy infrastructure and monolithic applications towards even a just a public cloud approach, let alone when you're moving to a more diverse architecture that involves multiple clouds, providers and geographies.

As well as this, while much of the focus, when it comes to multi-cloud, has been on application migration and compute, it is equally necessary to consider the implications having a more diverse approach to cloud computing might have on storage. In order to account for the broader industry trend of multi-cloud, many organisations are simultaneously exploring multi-cloud storage, which essentially extrapolates the concepts of multi-cloud to the storage arena. Although the act of employing this technique can be difficult and just as confusing as other aspects of digital transformation, as ascertaining just how to go about it, and determining the potential benefits and pitfalls relevant to a specific business, can be quite a struggle.

To account for this confusion, we spoke with Clive Grethe, Head of Application, Cloud, Transformation and Management Solution Sales at Atos. Grethe breaks down the fundamentals of multi-cloud storage, assessing it terms of why it is becoming a popular solution amongst enterprise organisations and what to look out for when deploying it.


What is multi-cloud storage? How do you best define it?

With the growth in cloud, most enterprises now use multiple clouds; private, on-premise, hosted and public. Multi-cloud storage is its natural extension. You cannot have computing ability without storage and data to process. So, when we talk about multi-cloud, we mean multi-cloud storage.
