Best practices for global enterprises moving to multi-cloud environments
Whether they set out to use multiple clouds or not, large enterprises today end up with several cloud suppliers. In fact, it’s probably hard to find a company that isn’t using some mix of Microsoft Azure, Amazon AWS, IBM Cloud, Salesforce.com, Oracle, Google G suite, ServiceNow or Box. The list goes on and on. This is more pronounced with enterprises that have a global site footprint.
The cloud, after all, gets you out of the business of hosting applications and constantly worrying about upgrading hardware and software. It also enables you to sidestep the capital commitments otherwise required.
However, the more clouds your enterprise uses, the more complex connectivity becomes. Security concerns skyrocket as it becomes hard to figure out who is accessing what, from where, and how. In addition, the network becomes central to application performance across the organization.
Forces at Work
Despite the network challenges that multi-cloud creates, there is no turning back. Multi-cloud is here to stay and will become even more complex with time, as:
- Companies turn to more SaaS offerings that enable them to embrace best-of-breed solutions rather than multi-purpose on-premises solution bundles that have to meet various requirements of legacy environments
- Technologies, such as serverless computing and other advances, that are only possible with cloud native applications attract more enterprise workloads
- Adoption of Internet of Things technologies and strategies require organizations to collect and analyze data closer to scattered sensors at the edge of the network, probably in specialized cloud services
- Companies try to mesh cloud tools with on-premises systems in hybrid configurations because stringent security or compliance requirements — or the tightly integrated nature of those legacy systems — prevents going all in with cloud
