Strategic considerations of hybrid and multicloud operations
Best practices encourage customers to create a single centralized cloud adoption strategy by using the Cloud Adoption Framework for Azure Strategy methodology. If you haven't already, use the strategy and plan template to record your cloud adoption strategy. This article introduces some technical considerations about hybrid and multicloud operations that might affect your strategy.
Common motivations for a hybrid and multicloud scenario
A hybrid and multicloud scenario isn't a strategy. It's a technical approach with dependencies on specific architectures and tools that can accelerate business and technology strategies. The following common strategic motivations can be affected by using a hybrid and multicloud scenario:
Critical business events: Responding to critical business events is a common driver for hybrid and multicloud adoption. The ability to connect multiple environments with hybrid networks and move workloads between platforms allows technology staff to respond rapidly and more effectively to:
- Business changes from a datacenter exit.
- Merger/acquisition events.
- Changes to regulatory compliance.
Migration motivations: Looking beyond immediate and critical events, migration and modernization motivations strive for midterm optimization of technology costs, operational complexity, and business agility. Connectivity between the current environment and the cloud provider allows for one-way migration capabilities. Use of abstraction layers, like containers, Kubernetes, or Azure Kubernetes Service (AKS), streamlines the migration process.
Innovation motivations: When you build solutions to drive long-term innovation, a hybrid and multicloud scenario might accelerate development efforts. Containers, Kubernetes, and AKS allow developers to build solutions with fewer dependencies on the features of any one cloud platform. Azure Stack HCI, Azure Stack Hub, and Azure Stack Edge allow developers to continue innovating with cloud native solutions, even in the local, on-premises datacenter. Conversely, connectivity across multiple clouds allows developers to maximize the use of cloud native services on their chosen platform while they integrate across those clouds for holistic enterprise environments.
Review a detailed list of common motivations to see which of the preceding motivations most closely maps to your organization's strategy.
Hybrid and multicloud outcomes
Before you execute on any cloud strategy, the cloud strategy team should establish a clear set of measurable business outcomes to track progress. A hybrid and multicloud scenario alone is unlikely to deliver any of the common business outcomes. But enabling a hybrid and multicloud approach is often a required milestone and is often tracked as a key result required to unlock business outcomes.
A hybrid and multicloud scenario is also commonly used as a tactic to accelerate the following business outcomes:
- Agility, global reach, and customer outcomes: The ability to move between cloud providers allows businesses to more easily deploy to the cloud platform that can best address these business outcomes.
- Application innovation, data innovation, and data democratization outcomes: Each outcome is accelerated by allowing development and analytics teams to manage and work with applications and data, regardless of the chosen cloud platform.
Impact of cloud mix on your strategy
Your hybrid and multicloud strategy for applications and data will drive the answers to the following questions. Clearly identify what intended cloud mix is required, then consider the best configuration for your environments:
- What mixture of hybrid, edge, and multicloud environments do you support today?
- What mixture best aligns with your strategy for the future?
- Do you want to operate each platform independently or through a unified operations approach?
Consider the best configuration for your environments, with a clear understanding of your intended cloud mix.
Review the range of decisions in the following chart, with examples of cloud mixes, and confirm what Azure landing zone option you have chosen. Before you configure any cloud environment, identify how it will support your specific mix of cloud hosting decisions.
Each dark blue dot represents a workload, and each light blue circle a business process, supported by a distinct environment. Each cloud mix requires a different Azure environment configuration for each customer.
Hybrid-first customer: Most workloads stay on-premises, often in a mixture of traditional, hybrid, and portable asset-hosting models. A few specific workloads are deployed to the edge, Azure, or to other cloud providers.
Azure-first customer: Most workloads have been moved to Azure. A few workloads stay on-premises. Strategic decisions have led to a few workloads living on the edge or in multicloud environments.
Multicloud-first customer: Most workloads are currently hosted on a different public cloud, like GCP or AWS. Strategic decisions have led to a few workloads living in Azure or on the edge. You may be moving from a hybrid-first mix to an Azure-first mix as your cloud strategy matures. We also support customers making strategic decisions to prioritize hybrid or multicloud mixes, and Azure plays a role in each mix.
Unified operations key considerations
There might be diverse strategic impacts as a result of various hybrid and multicloud decisions. But there's one constant consideration in any strategy that involves a hybrid and multicloud scenario. Investments in unified operations and a single cloud control plane will reduce roadblocks to your hybrid and multicloud projects. The following key considerations are important for unified operations:
- Improved visibility and control over the IT estate: Organizations might need the ability to see all their resources in a single location and be able to query through them to gain insights.
- Cloud-based management: Organizations might want the ability to modernize operations across platforms with the same cloud management services on resources in locations that are outside of Azure.
- Governance: Organizations might want to ensure consistent configurations across all resources from one central location.
- DevOps and flexible, cloud-native application deployments: Organizations gain the agility to deploy application infrastructure through templates and application configurations through GitOps.
- Increased flexibility with platform as a service (PaaS): Organizations also benefit from the ability to run PaaS services on their infrastructures of choice.
Deploying a single enterprise control plane can accelerate hybrid and multicloud adoption. Organizations can develop cloud readiness with cloud skill-building efforts and process improvements that assume unified operations. Bring innovative cloud practices and technologies to on-premises environments, while you prepare other workloads for migration to the cloud. A single cloud operations management dashboard can help you to manage and govern your operations consistently across on-premises, multicloud, and edge environments. You gain greater visibility into assets scattered across environments, cross-team accountability, and faster, consistent, and at-scale deployments for developers.
Accelerate hybrid and multicloud adoption with unified operations
Starting comprehensive cloud readiness and skill-building initiatives can accelerate cloud adoption and migration efforts across your organization. Assess and advance cloud readiness, implement innovative cloud practices in your workloads that will remain on-premises, and adopt cloud technologies to prepare other workloads that you might move to the cloud. Work with your cloud strategy team to build the necessary cloud skills and processes to prepare for your migration effort to a hybrid and multicloud environment.

A combination of hybrid and multicloud environments is the most common scenario found across today's enterprise IT landscape. For most customers, moving to a hybrid and multicloud scenario embraces market reality and is motivated by a sound business strategy. The next decision for your organization is to commit to a distributed cloud computing model that can increase the speed of your cloud adoption and migration efforts.
Initiating a cross-team effort to increase your cloud readiness with innovative cloud practices and technologies is the first step toward implementing a single enterprise control plane. You can consistently protect and monitor resources, standardize governance and security, and manage your operational processes in on-premises, multicloud, and edge environments. Consider a hybrid and multicloud environment to manage your overall digital estate if you're planning a hybrid strategy by design for the next 12 months or longer.
Work with your cloud strategy team to build the necessary skill levels and processes to prepare the move to an enterprise control plane across a hybrid, multicloud, and edge environment that encourages greater accountability within IT teams, empowers developer teams, and extends Azure services to any infrastructure, anywhere.
Unified operations motivations
Various motivations might steer customers to adopt a hybrid and multicloud approach. Adopting the right cloud strategy depends on documenting what classification most these motivations are associated with. Are they related to critical business events, migration, or innovation?
Customers might have a digital estate that's bound by specific regulatory requirements and data localization laws that constrain in which geographic location it must reside. A particular industry might require low latency and high connectivity for efficient operational capacity, such as financial services. Low-latency and high-connectivity are common requirements for other industries like media, healthcare, education, and government.
A multinational organization, for example, might have globally distributed, legacy datacenters, with an aging infrastructure that's not compatible with a company-wide migration effort. Or, there might be corporations with even larger cloud estates that are sprawled across several cloud environments, where visibility and control of IT operations is challenging.
