Deciding which workloads to move to the cloud first is a sequencing question, not a vote for moving everything. A critical application may matter greatly to the business but still be a poor first migration if it is tightly connected to other systems, difficult to recover, or dependent on reliable local connectivity.
For a small business, a useful starting point is to compare each workload’s business impact, dependencies, cloud readiness, recovery needs, connectivity, data constraints, and ongoing operating cost. The goal is to make a deliberate choice: move a workload, keep it on-premises for now, or use a hybrid arrangement.
Separate business importance from migration readiness
Start by listing the applications and services your organization depends on. Include the less visible pieces, such as databases, identity services, file shares, integrations, backup systems, and connections to physical equipment. A workload is more than the application employees see on their screens.
Then consider two separate questions: How important is this workload to business operations? And how ready is it to move without creating avoidable disruption? A system can be highly important and still be a later migration candidate if it has many dependencies or needs careful recovery testing.
This distinction helps prevent a common planning mistake: putting the most important system first simply because it deserves attention. Importance should determine the care and planning it receives. Readiness, dependencies, and risk should help determine its place in the migration sequence.
Use a workload scorecard
For each workload, record a short assessment. You do not need a complicated scoring model to make the comparison useful. Use consistent notes and describe what you know, what is uncertain, and what needs to be tested.
- Business impact: What work depends on the workload? What would employees, customers, or business processes be unable to do if it were unavailable?
- Dependencies: Which databases, identity tools, integrations, network paths, devices, or other applications does it rely on? What relies on it?
- Cloud readiness: Can it run in a cloud environment as it is, or does it depend on an older operating system, specialized hardware, or a configuration that needs review?
- Recovery needs: How quickly must the workload be restored, and how much recent data could the business afford to recreate? Document the recovery time objective (RTO) and recovery point objective (RPO) that the business requires.
- Connectivity: Does it need a dependable internet connection to function? Must it continue operating if that connection is interrupted? Does it need to communicate quickly with a local device or system?
- Data and controls: What information does it handle, who should access it, and what security, privacy, or compliance requirements apply? Identify the specific requirements and controls rather than assuming a category of data automatically dictates where it must run.
- Operating cost and effort: Compare the expected ongoing cloud costs and management work with the costs and effort of keeping the workload local. Include backup, monitoring, connectivity, licensing, and support considerations.
Microsoft’s workload assessment guidance and AWS’s migration prioritization guidance offer additional ways to assess workloads and plan migration order.
Choose an appropriate first workload
A suitable early candidate is often useful but not deeply entangled with other systems. It should have clear ownership, known data and access requirements, and a recovery approach that can be tested. A nonproduction workload or a standalone service may be a reasonable pilot if it reflects the kinds of technology and operating processes your team will need to manage.
A pilot should test more than whether the application starts in its new environment. Check how users connect, whether integrations work, how backups and restores behave, whether security controls are in place, and who responds when something goes wrong. Use what you learn to improve the plan before moving workloads with greater business impact.
After an initial migration, group suitable workloads into later waves based on shared dependencies and operational needs. Keep a record of the reasons for the order so the plan remains understandable to both technical staff and business owners.
Map dependencies before moving connected systems
If an application depends on a database, identity service, file share, or another application, assess the connection between them before deciding on a migration date. Moving only one part can introduce latency, connectivity problems, or a failure path that was not obvious when the systems were running together.
That does not mean every connected component must always move at the same time. It means the team should know how each component will communicate during and after the transition, whether a temporary split arrangement is workable, and how to reverse or recover the change if testing fails.
Draw a simple dependency map and confirm it with the people who use and maintain the systems. Include vendors or service providers when they own parts of the application or its connections. If the map has unanswered questions, resolve them before treating the workload as ready.
Let recovery requirements influence placement
RTO describes how quickly a service needs to be restored after an interruption. RPO describes how much recent data the business can tolerate losing or needing to recreate. These are business requirements to document and test, not just settings to select during migration.
Compare the workload’s required recovery outcomes with the proposed cloud, on-premises, or hybrid design. Check that backups cover the necessary data, that restore steps are understood, and that recovery does not depend on an unavailable system or person. If a workload has demanding recovery needs, plan and test its recovery approach before moving it, even if the cloud destination seems suitable.

When on-premises or hybrid may fit better
Keeping a workload on-premises can make sense when it relies on specialized local equipment, needs very responsive communication with nearby systems, or must continue operating during an internet outage. It may also be the practical choice when the application is not supported in a cloud environment or the work to change it is not justified yet.
Hybrid placement can be useful when part of a process benefits from cloud resources but another part needs to stay close to local users, devices, or data. The tradeoff is that hybrid environments require clear ownership of connectivity, identity, monitoring, security, and recovery across both locations.
For every workload that stays local, document why it remains there, what risks or dependencies affect that decision, and what would prompt a review. On-premises should be an intentional placement, not a destination chosen simply because nobody has assessed the alternatives.
Make compliance and modernization workload-specific
Compliance considerations depend on the data, the service, applicable obligations, and the controls in place. Do not assume that regulated information must automatically stay on-premises, or that moving it to a cloud provider settles the organization’s responsibilities. Identify the requirements that apply, then verify how the proposed design addresses access, protection, retention, monitoring, and recovery.
For healthcare organizations, a cloud decision should account for the systems handling sensitive information and the safeguards around them. This healthcare cloud migration checklist can help frame those considerations.
Whether to migrate a workload as-is or modernize it first depends on its condition and the reason for moving it. A move as-is may be a way to change hosting without redesigning the application, but it does not automatically resolve technical limitations or operational problems. Modernization may improve fit, but it adds work that should be planned and tested. Decide based on the workload’s dependencies, supportability, risk, and business goals rather than treating either path as the default.
Frequently asked questions
Can healthcare data be stored or processed in the cloud?
It may be possible, but the decision depends on the specific data, requirements, provider arrangements, and safeguards. Identify applicable obligations and verify the proposed controls before selecting a destination.
What should stay local if a workload needs low latency or must work without internet access?
Assess whether the workload can continue operating locally during a connection outage and how quickly it must communicate with nearby equipment. A local or hybrid design may fit better when those needs cannot be met reliably in the cloud.
Is it better to migrate a workload as-is or modernize it first?
Choose based on the workload’s condition and migration goals. Moving it as-is may limit the scope of change, while modernization can address fit or supportability concerns but requires additional planning and testing.
Build the sequence around evidence
The most sensible cloud migration sequence is the one that reflects business impact, dependencies, recovery needs, connectivity, data requirements, and ongoing operating effort. Start with a manageable pilot, learn from it, and move more complex workloads only when their dependencies and recovery plans are understood.
