The clouds involved are generally different public cloud platforms, such as AWS, Azure, and Google Cloud. In some situations, a multi-cloud system might also incorporate private on-premise infrastructure.</p><p>Several factors have contributed to the uptick in multi-cloud adoption over the past few years:</p><ul><li><strong>Businesses want access to the best features of every cloud.</strong> Although each public cloud offers broadly similar services, individual platforms may offer more or fewer features around specific components. Some platforms are narrowly focused on particular technologies, such as Kubernetes and containers, whereas others take a more general-purpose approach. Organizations might want to deploy computing nodes from the most cost-effective provider while using a focused solution for their Kubernetes clusters.</li><li><strong>Avoiding vendor lock-in.</strong> Using public clouds makes enterprises dependent on external providers. Adopting a single platform creates a risk of becoming locked in, making it harder to switch in the future. Multi-cloud encourages portability of applications and data. This strategy can help mitigate outages in specific clouds, and also affords more flexibility for future changes.</li><li><strong>Supporting edge computing.</strong> More workloads are moving to the edge to sit closer to users. Adopting multiple clouds can be advantageous in this situation. Extending your service to new regions could be problematic if your existing cloud lacks datacenters near those customers; a multi-cloud approach lets you provision infrastructure from the optimal provider for each scenario.</li></ul><p>In a hypothetical application, splitting the database, authentication service, and storage across three clouds removes failure points when compared to the single-cloud approach. Your app’s core capabilities would still work if the cloud hosting the storage component experienced a problem, as the outage wouldn’t impact the physically separate auth and database components.</p><div></div><h3 id="multi-cloud-must-haves"><span class="group">Multi-cloud must-haves<a class="select-none opacity-0 !transition group-hover:opacity-100" href="#multi-cloud-must-haves" aria-hidden="true"> <svg class="inline" xmlns="http://www.w3.org/2000/svg" width="0.4em" height="0.4em" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round"><path d="M15 7h3a5 5 0 0 1 5 5 5 5 0 0 1-5 5h-3m-6 0H6a5 5 0 0 1-5-5 5 5 0 0 1 5-5h3"></path><line x1="8" y1="12" x2="16" y2="12"></line></svg></a></span></h3><p>Effective adoption of a multi-cloud system requires a holistic approach from the start.

A platform that lets you track all your assets is essential. This platform should map out your system, manage components across clouds, and identify opportunities for optimization. <a target="" rel="noreferrer" href="https://www.ibm.com/docs/en/cloud-private/3.2.0?topic=multicloud-manager">IBM Multicloud Manager</a>, <a target="" rel="noreferrer" href="https://cloudify.co/">Cloudify</a>, and <a target="" rel="noreferrer" href="https://www.bunnyshell.com/">Bunnyshell</a> are some options you can use.</p><h4 id="seamless-data-transfers-between-clouds"><span class="group">Seamless data transfers between clouds<a class="select-none opacity-0 !transition group-hover:opacity-100" href="#seamless-data-transfers-between-clouds" aria-hidden="true"> <svg class="inline" xmlns="http://www.w3.org/2000/svg" width="0.4em" height="0.4em" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round"><path d="M15 7h3a5 5 0 0 1 5 5 5 5 0 0 1-5 5h-3m-6 0H6a5 5 0 0 1-5-5 5 5 0 0 1 5-5h3"></path><line x1="8" y1="12" x2="16" y2="12"></line></svg></a></span></h4><p>Multi-cloud is most effective when data can flow directly between the individual platforms you’re using.

This works well with <a target="" rel="noreferrer" href="https://en.wikipedia.org/wiki/Infrastructure_as_code">infrastructure as code</a> (IAC) approaches, where infrastructure components are defined as files in a version-controlled repository.

No matter how many tools you add, you’re still going to need accounts with several cloud providers and new workflows for deploying, networking, and maintaining your applications. It can be harder to track down bugs and isolate problems when your workloads are spread across physically separate environments. Although multi-cloud removes some failure points, it can also create new ones if intercloud networking goes awry. Not acknowledging the complexity and its learning curve could create confusion and cause errors during management activities.</p><h4 id="multi-cloud-authentication-and-management"><span class="group">Multi-cloud authentication and management<a class="select-none opacity-0 !transition group-hover:opacity-100" href="#multi-cloud-authentication-and-management" aria-hidden="true"> <svg class="inline" xmlns="http://www.w3.org/2000/svg" width="0.4em" height="0.4em" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round"><path d="M15 7h3a5 5 0 0 1 5 5 5 5 0 0 1-5 5h-3m-6 0H6a5 5 0 0 1-5-5 5 5 0 0 1 5-5h3"></path><line x1="8" y1="12" x2="16" y2="12"></line></svg></a></span></h4><p>Multi-cloud demands special attention to <a target="" rel="noreferrer" href="https://tailscale.com/kb/1085/auth-keys/">user authentication</a> and session management.

You’ll need to orchestrate data backups and replication across all your cloud providers to ensure you’re protected from disasters. Similarly, restoration of backups will need to be tested on each platform. Restorations might complete at different rates, leaving some components functional while others in separate clouds are still recovering.</p><p>Redundancy strategies must be considered as well.
