Ready: Prepare your environment for a hybrid and multicloud scenario
The Ready methodology of the Cloud Adoption Framework for Azure guides customers through environment readiness to prepare for cloud adoption. The readiness section includes technical accelerators (Azure landing zones), which are the basic building block in any cloud adoption environment. Review your choice of what landing zone to deploy. If you need help choosing the right one to deploy, this guide can help you get started. If you are considering what landing zone would best fit your organization's operating model, this article can help you get started with this alignment.
Hybrid and multicloud landing zones
Landing zones automate the configuration of your Azure environment, and align with best practices guidance in the Cloud Adoption Framework. When you prepare for a hybrid and multicloud deployment, environment configurations might be slightly different.
These are the key changes necessary to prepare a consistent environment for any hybrid and multicloud deployment (hybrid and multicloud landing zone):
- Hybrid and multicloud network connectivity
- Common identity management
- Integrated management and security
- Unified operational process controls for operations, governance, and compliance
- Unified and consistent development and DevOps across heterogeneous environments
This article guides you through the considerations required for these environment configurations.
Configure your initial Azure environment
For each cloud mix above, you'll need an Azure environment to support, govern, and manage your cloud resources. The Ready methodology of the Cloud Adoption Framework helps prepare your environment by using a few steps:
- Consider each of the Azure landing zone design areas to properly evaluate your technical requirements.
- Compare your requirements to the Azure landing zone implementation options to find and implement the most suitable template to start your configuration.
- Do you have an existing Azure environment to transition into enterprise-scale?
Evaluate your cloud mix
Choosing a hybrid and multicloud environment isn't a binary decision. It's closer to a range of decisions, as seen in the following chart. Confirm what Azure landing zone option you have chosen.
Before you configure your Azure environment or any other cloud environment, it's important to identify how your cloud environment will support your specific mix of cloud hosting decisions. Here are some examples of common cloud mixes.
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, as seen with our three reference customers:
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.
Harry's Harvesters is a hybrid-first customer, with a heavy investment in aging datacenters. Cost and governance are its highest priorities. Legacy IT priorities and aging technology infrastructure hindered innovation, which drove some early cloud adoption.
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.
Angie's Applications is an Azure-first customer. Like Harry's Harvesters, it completed its first wave of digital transformation, acquired a few companies, and added customers in regulated industries. Innovation is still its priority. But with its multicloud environment, it's focused on operations management, and efficient, scalable operations required to continue its acquisition strategy.
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. Each month, we see a steady flow of customers moving from a hybrid-first mix to an Azure-first mix as their cloud strategy matures. But, we also support customers who have made strategic decisions to prioritize hybrid or multicloud mixes. Azure plays a role in each mix.
Mary's Markets is a multicloud-first customer. Like Angie's Applications, it moved to the cloud, but didn't choose Azure. It also has some local datacenter assets and edge devices. Mary's Markets is an early adopter of other clouds in an early startup phase, and growth is its big priority. Driving growth in hybrid and multicloud are the retail requirements of its customers, and the need to improve operations in order to scale efficiently.
The following considerations are most important when preparing any of your cloud environments for hybrid and multicloud. 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?
Modify your environment to reflect your cloud mix
All three customers will have to deliver on slightly different strategic requirements to succeed in their digital transformation.
- Harry's Harvesters will need to focus on a migration and governance strategy to achieve cost controls, while ensure continued compliance.
- Angie's Applications will continue to invest in innovation but also needs to focus on a strategy to optimize operations, as they innovate.
- Mary's Markets will need to focus on migration and scaling operations to continue to grow their market share.
These customer all have different strategic, operational, governance, and environmental requirements. There is no one-size-fits-all solution to prepare them for their unique journeys to hybrid and multicloud. But they do all have one common need before they make impactful decisions: visibility.
Starting on different paths, each customer's first step in its cloud journey is the same: to onboard hybrid and multicloud assets into Azure Arc at no costs, and gain visibility across workloads and cloud providers. While their strategic focus will differ, the starting point remains the Cloud Adoption Framework, each accomplishing its strategic objective by following guidance in different methodologies.
- Harry's Harvesters needs visibility into inventory and costs. Following guidance in the Strategy and Govern methodologies, it will focus on governance and cloud migration to reduce cost and shift to OPEX cost models.
- Angie's Applications needs connectivity between clouds and new operational innovations. It will follow guidance in the Innovate and Manage methodologies, with a focus on cloud-native innovation and Azure landing zones for cross-cloud connectivity.
- Mary's Markets needs to scale workloads, and support demand from retail customers. It will follow guidance in the Migrate and Manage methodologies, focusing first on the operations baseline to prepare for scale, then a limited migration to Azure.
Each customer now needs to address network, identity, governance, and operations management to ensure proper environmental configuration. With their slightly different requirements for operations and environmental configuration, they'll use different implementation options with Azure landing zones:
- Harry's Harvesters' operational requirement is to modernize existing operations into new environments, and quickly build a compliant environment for its entire datacenter in Azure. It's ambitious plan is to migrate out of its organization's local datacenters, requiring compliance from day 1. The fastest path to its objectives is via enterprise-scale landing zones.
- Angie's Applications' operational requirement is to ensure consistent environmental configuration and control, adding hybrid and multicloud configuration to existing environments. It started with a smaller landing zone footprint and grew over time, and it's now in the expand phase of the start small and expand approach to Azure landing zones. The company will use the operations baseline in the Manage methodology and the decision trees in the Ready methodology to move forward.
- Mary's Markets has an operational goal to configure Azure and a hybrid environment to work with existing cloud configurations, using third-party options to extend its multicloud expertise to Azure and a hybrid environment configuration. The organization has invested heavily in Terraform to build their multicloud environments. It will start with the CAF Terraform modules to start small and expand into the hybrid environment, integrating with their existing cloud solutions.
Support the most appropriate cloud mix
After establishing your Azure environment, consider modifications to:
- Identity: Which cloud will host your primary identity provider? If that provider is outside of Azure, you might need to integrate your identity provider with Azure Active Directory. For more information, see Identity providers for external identities.
- Public network connectivity: Best practices suggest that all ingress and egress traffic should route through one cloud platform when possible. But your requirements or cloud mix might require more of a peer model. This arrangement is especially common if your cloud mix is used to satisfy redundancy and reliability requirements. How will you configure connectivity between each cloud platform and the public internet?
- Backup and recovery: It's common for customers to centralize their backup and recovery strategy around the most reliable provider in their cloud mix. Often the result is that one of the cloud providers serves as a shared recovery center. Azure Backup and Azure Site Recovery can help in each case.
- Cloud platform connectivity: If your cloud platforms will share common recovery, operations, or governance resources, you might require connectivity between each cloud platform. How will you configure connectivity between each cloud platform?
The most important consideration
Will you operate each cloud independently or through a unified central operations approach?
Independent operations can double or triple your total cost of ownership (TCO). For some customers, TCO cost increases can be multiplied by over 10 times. To minimize costs and demands on your staff, a unified operations approach is best for all cloud mixes for your hybrid and multicloud strategy.
