Multicloud is the use of cloud services from more than one cloud vendor. It can be as simple as using software-as-a-service (SaaS) from different cloud vendors–e.g., Salesforce and Workday. But in the enterprise, multicloud typically refers to running enterprise applications on platform-as-a-service (PaaS) or infrastructure-as-a-service (IaaS) from multiple cloud service providers, such as Amazon Web Services (AWS), Google Cloud Platform, IBM Cloud and Microsoft Azure.
A multicloud solution is a cloud computing solution that's portable across multiple cloud providers' cloud infrastructures. Multicloud solutions are typically built on open-source, cloud-native technologies, such as Kubernetes, that are supported by all public cloud providers. They also typically include capabilities for managing workloads across multiple clouds with a central console (or 'single pane of glass'). Many of the leading cloud providers, as well as cloud solution providers such as VMware, offer multicloud solutions for compute infrastructure, development, data warehousing, cloud storage, artificial intelligence (AI) and machine learning (ML), disaster recovery/business continuity and more.
The overarching value of multicloud to the enterprise is that it prevents ‘vendor lock-in’, performance problems, limited options, or unnecessary costs resulting from using only one cloud vendor. A multicloud strategy offers organizations:
The key to maximizing the benefits of a multicloud architecture is to manage applications and resources across the multiple clouds centrally, as if they were part of a single cloud. But multicloud management comes with multiple challenges including:
Organizations use multicloud management tools–or preferably, a multicloud management platform–to monitor and manage their multicloud deployments as if they were a single cloud environment. The best multicloud management platforms typically offer:
Hybrid cloud is the use of both public cloud and private cloud environments, with management, orchestration and portability between them that enables an organization to use them as a single, unified, optimized IT infrastructure.
Multicloud and hybrid cloud are not mutually exclusive. In fact, most enterprise hybrid clouds are hybrid multiclouds, in that they include public or private cloud services from at least two cloud service vendors.
Hybrid multicloud builds on multicloud benefits with:
Continuously automate critical actions in real time—and without human intervention—that proactively deliver the most efficient use of compute, storage and network resources to your apps at every layer of the stack.
Build apps faster and deploy them consistently across on-premises, edge computing and public cloud environments from any vendor.
Quickly and securely containerize and deploy enterprise workloads in Kubernetes clusters. Because IBM manages OpenShift Container Platform (OCP), you'll have more time to focus on your core tasks.
Innovate faster, reduce operational cost and transform IT operations (ITOps) with an AIOps platform that delivers visibility into performance data and dependencies across environments.
IBM Hybrid Cloud Mesh offers simple, secure and predictable application-centric connectivity.
An open hybrid cloud environment is built on an open-source architecture, providing flexibility by working within your IT architecture no matter what kind of architecture it is.
Cloud computing transforms IT infrastructure into a utility, letting you ‘plug in' to computing resources and applications over the internet, without installing and maintaining them on-premises.
Automate deployment, management and scaling of containerized applications using this open-source container orchestration platform.
Consider hybrid multicloud DevOps friendly, application-centric connectivity.
With IBM Cloud Satellite you can deploy and maintain applications consistently across multicloud environments, with greater global visibility and less management complexity. Use a single API to create a distributed cloud location, then add host machines from any cloud, on-premises data center, or from the edge. And consume common set of cloud services, including toolchains, databases and AI, in any location.
