What Is A Cloud Migration Strategy?
An organization's plan for moving its current workloads and data from on-premises or co-located environments onto public clouds such as Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure is known as its cloud migration strategy.
Most application landscape workloads can benefit from cloud migrations; however, not all. To implement an effective cloud migration strategy, it's essential to prioritize workloads, determine an ideal migration process for each workload, conduct a test pilot and adjust according to results.
Cloud migration strategies must also be documented so teams can navigate the migration process more easily while supporting rollbacks when necessary.
Why Should You Use A Cloud Migration Strategy?
An organization's plan for moving current workloads and data from on-premise or co-located environments onto public clouds such as Amazon Web Services (AWS), Google Cloud Platform (GCP), or Microsoft Azure is known as its cloud migration strategy.
Most workloads can benefit from migration; however, not all can do business-critical applications. Implementing an effective cloud migration strategy involves prioritizing workloads, developing an ideal migration tools plan for each workload and conducting a test pilot with adjusted results based on results.
Cloud migration strategies plans must also be documented so teams can easily navigate their migration processes while facilitating rollbacks when necessary.
What Are The Advantages Of Cloud Migration?
- Careful preparation can save both time and money when planning a cloud move. Migration could take several months to years, depending on which platforms exist at both ends, but with reliable infrastructure in place, migrations may be automated and executed massively without disrupting business activities.
- Many businesses turn to cloud providers for their IT modernization projects, employing microservices and APIs with contemporary containerized apps to implement cloud native strategies. Cloud providers utilize the most up-to-date servers and storage facilities, freeing companies from upgrading OS or RAM and focusing on addressing business problems instead.
- Migrating to cloud services enables businesses to instantly scale up or down depending on seasonal fluctuations, growth projections, or any unexpected spikes in demand. Furthermore, only those resources used will incur costs.
- Moving to the cloud can enhance security. Although most cloud providers use a shared responsibility model, cloud infrastructure is typically much larger than an organization's on-premises. Cloud providers frequently offer security analytics and can block unwanted traffic and automatically update OS and security upgrades - meaning end users have access to their cloud-based data at any time without worrying about having the latest hardware.
- Migrations to the cloud increase accessibility. Workers can access essential company apps and data while working from home or traveling, so employee productivity increases significantly. With everything already hosted on the cloud, access is unaffected by machine outages allowing operations to continue nearly uninterruptedly.
Migration to the cloud can also greatly enhance access to applications. Cloud-native apps feature APIs that promote sharing information between services and apps regardless of their locations, providing a standard communication method among apps and more accessible access to information that was once limited to single apps - this way, data can now be easily and predictably shared between services.
How Does A Cloud Migration Strategy Work?
Before selecting migration techniques for their apps, companies should carefully consider their architecture, requirements and budget before cloud vendors select migration approaches.
Furthermore, time, resources available and abilities required must also be factored into their decisions. First, the team should assess the available resources before ascertaining their maturity level for each assignment; each app may need a comprehensive discovery study.
Design your migration with clear milestones and goals in mind. Each task should have an appropriate time frame. A pilot project should also be included, starting with the relocation or rehosting of one task - this can help identify gaps and adjust as necessary.
To effectively execute large-scale migrations, organizations must focus on optimizing three points:
- Customize applications and examples for maximum performance.
- Focus on governance and operations.
- Create the Managed Services Team to oversee Migration and Operations.
What Types Of Cloud Migration Strategies Are There?
When considering the migration of workload, there are many options.
- Relocating: Moving This is the easiest form of migration, involving moving virtual machines from hardware on-premises to VMC and can be accomplished either through reprovisioning cold migration or live migration.
- Reprovision: Although not strictly a migration option, reprovision may be suitable for certain cow workloads. Instead of moving existing workloads over, creating new workloads on Cloud in AWS might make more sense; you could bring these up in the cloud as new workloads and shut down older ones on-premises.
- Cold Migrating: This migration strategy involves moving a stopped workload directly to Cloud in AWS for restart. It may be ideal for non-production workloads that can easily be switched off without disrupting business (e.g. development and test workloads). This option also can help save on costs associated with production migrations.
- Live Migration: between your on-premises environment and Cloud SDDC on AWS must be an essential feature of a hybrid cloud deployment strategy, which vMotion makes possible.
- Replatforming: In this model, certain components are modified or replaced to take advantage of cloud providers' features more effectively, for instance, by switching to managed service or replacing commercial off-the-shelf software with open-source solutions.
- Repurchasing: involves replacing an existing cloud-based application with one available from a cloud provider's market, effectively exchanging license fees for another product or service. This approach is often taken for old on-premises applications that provide similar functionality but cannot easily virtualize-need help to grate, such as ERP, Finance, CRM or HR software. Repurchasing also makes sense for older applications that are public cloud providers difficult or impossible to virtualize or migrate; such applications could use this route instead.
- Refactoring: The approach entails completely revamping an application to leverage the unique features of cloud providers, taking full advantage of cloud native capabilities or microservice-based applications' agility requirements. If cloud native capabilities or microservice-based application agility necessitate it, these applications will be broken into smaller services or pieces before being deployed on one or multiple public clouds. This approach may be costly, but it offers substantial returns that outweigh its risks. As cloud native applications become more prevalent, applications migrated using other migration strategies will need refactoring or a complete redesign to take full advantage of cloud native capabilities. This strategy may need re-re-factoring over time.
- Retaining: This option does not involve migration but rather keeping an on-premises application running, such as on mainframes or minicomputers that still have significant investments. As a result, hybrid migration strategies include workloads from both public and private cloud providers.
- Security Concerns: Cloud services enact a shared responsibility model, so workloads must be protected using zero-trust transactions whenever possible to maintain statelessness.
- Compliance and Governance: Regulations may vary by geography and industry. Cloud service providers provide physical storage space for an organization's information; however, whether or not their customers comply with regulatory requirements regarding data retention and privacy remains entirely up to them.
- Cost Control: Each organization has to ensure that new workloads and accounts are deleted and applications don't unnecessarily duplicate themselves, leading to virtual machine sprawl and container sprawl.
- Retiring: Discontinuing All applications become obsolete over time due to outdated features or superior cloud-based alternatives.

What Are Some Of The Challenges Associated With A Cloud-Based Migration Strategy?
Migrations from public clouds can often result in unsuccessful or delayed migrations. Organizations should devise a comprehensive migration plan and understand which workloads must be relocated and why.
They should wait to attempt to move every workload to the cloud; teams from operations, application cloud migration strategy infrastructure and development must participate in numerous cloud migration process efforts.
At first, it is crucial to determine your desired goal and then realistically assess how long it will take you to attain it.
Also essential is identifying the optimal solutions for legacy applications and servers, some of which may be suitable for cloud migration projects while others still need to be moved there. Finally, consideration must be given to connectivity for apps application performance disposing of old hardware or real estate located within data centers.

Cloud Migration Strategy: The Six R's
Rehost
Rehosting is the ideal solution to migrate an Oracle database quickly hosted on-premises to AWS at an economical cost, cost savings, increasing performance and speed simultaneously.
Rehosting can be automated using tools such as CloudEndure Migration or AWS VM import/export, or manual implementation is also possible for reaching cloud maturity. Using functions such as ephemeral computing or autoscaling could be limited; legacy and resource-intensive programs could suffer latency issues from being incompatible.
Rehost The Page If:
- Migrating large-scale enterprise
- Cloud computing is a new phenomenon.
- Migrating applications from the shelf
- Migrating to a new location with a set deadline
Lift and Tinker' is an alternative form of rehosting that involves adapting program settings for cloud services without major design modifications.
Developers commonly employ this strategy when adapting databases like Google CloudSQL, Amazon RDS or Microsoft Azure into usable formats with little risk to overall project integrity. Regular reviews must occur to minimize risks involved with full refactoring projects, as this reduces any unneeded modifications that might crop up later on.
Replatform your if you wish to:
- Migration in a hurry
- Benefits of cloud computing without having to refactor the application
- Migrate a complex app on premises with minor changes for cloud advantages
Refactor/Re-architect
Refactoring or Re-Architecting your application completely to make it cloud-native will allow for optimal utilization of cloud technologies like load balancers, containers, serverless computing, service-oriented architecture, microservices architecture and serverless computing.
For example, switching from an on-premises monolith to a serverless cloud architecture can reorganize your assets. Refactored apps are agile, scalable and effective; even in competitive markets, they provide substantial ROI over time.
This strategy will prove costly, time-consuming, and resource-intensive in the end. Lack of expertise with cloud technologies, difficulties associated with project or program delivery, and possible business interruption may pose additional obstacles.
Prioritize creating potential issues with microservices from your monolithic app's smaller components before beginning to refactor them - while you create the cloud-based version, allow existing apps to continue functioning normally on-premises to avoid disruptions to normal operation.
Use Refactor If
- Cloud computing will benefit your application in the most significant way
- Scalability, speed and performance are important business goals.
- Cloud compatibility is impossible for an on-premises app.
Purchase
"Drop-and-shop" or "repurchase" refers to an approach in which cloud native software from one vendor is replaced with on-premise applications, typically via SaaS programmes that offer similar consistent infrastructure functionality.
You then switch over your licensing model from on-premises licenses to cloud provider licenses for easier use and greater savings on maintenance and storage expenses.
Your options for migrating from on-premise CRM systems to access to enterprise apps Salesforce, Hubspot or Workday HRM could include Salesforce CRM or Hubspot CRM as an on-demand option, Drupal as a built-in CMS or purchasing software through SaaS platforms can be limited in costs across clouds customization options and control; losing one might prove disastrous.
Airbnb switched from MySQL to Amazon RDS as part of their move to AWS to better address scalability and replication - two complex processes that MySQL could not accommodate.
Amazon RDS took care of many time-consuming administrative chores related to databases so engineers had more time for new ideas; all data was successfully transferred over in under 15 minutes!
Repurchase HTML0 if you:
- Replace software that performs standard functions like finance, accounting and CRM.
- Cloud compatibility isn't possible with legacy apps.
Retire
The "retirement" plan is an approach for eliminating applications from your IT infrastructure that are no longer productive or valuable, such as applications that no longer serve their intended function or cloud with enterprise security dependencies within the company.
You may delete or scale back an application if moving it to the cloud is no longer worthwhile while considering usage, dependencies and costs to the business of any program in your portfolio.
Decommissioning applications is no simple task, so it's wise to be a multi-cloud environment mindful of their complexity when selecting which apps or services to decommission.
Planning early allows for the efficient migration of critical applications and services while decreasing migration needs overall, thus saving resources.
Use Retire if:
- Archives that have useful information.
- Save money by retiring applications that have duplicate functionality.
- Remove apps that microservices can replace.
Autodesk's migration to AWS, aimed at increasing productivity, automation and resilience through extensive migration, has telco clouds discontinued various programs as part of an ambitious migration effort.
Retain
Revisiting some key digital assets/applications that require extensive reworking before cloud migration is known as retaining, also known as revisit.
Some apps are better suited for an on-premise setup or were recently updated and should remain. Other apps may still be usable due to delay, regulatory restrictions or costs; others might even provide the functionality they once did to access applications.
Hybrid cloud deployment often involves retention strategies to ensure business continuity during long migration processes that may take years.
Retain is Used if:
- You choose a hybrid cloud during your migration.
- Your on-premise application investment is substantial
- The legacy application is compatible on-premises but not in the cloud
- If you decide to return later, it is possible.

- Workload Requirements
Application needs and maturity may affect migration tactics. Applications that demand high availability, low latencies or high performance often need cloud service providers that meet these criteria without incurring downtime.
To understand how mature each application is, an extensive discovery phase must occur for all native cloud services instances. The migration strategy must align with goals and milestones and provide reasonable time frames per task.
- Reduction of Costs
Capital and upfront investments are necessary when migrating a built-in distributed service business into the cloud, including costs related to transitioning to SaaS services, new purchasing resources, training employees in cloud administration and usage, and running both legacy and cloud systems concurrently until the migration is complete.
Your enterprise may hold back some workloads until the migration has concluded to be as cautious as possible during its migration journey.
- Security and Compliance
Organizations moving to cloud services must consider security issues, legal and regulatory constraints, privacy considerations and privacy regulations when planning their migration strategy.
AWS Key Management Service and AWS Identity Access Management are integral in providing safe encryption and access, closing security holes and meeting legal requirements. Businesses may keep certain critical data onsite while moving the rest to the cloud for improved data protection.
- Training and Development For Staff
Knowledge and expertise within an IT department of a company can have a tremendous effect on migration strategies.
An enterprise may need to train its staff or hire new members with expertise in certain cloud technologies or providers for effective migration strategies.
- Staying Up To Date With The Future
Technology advances rapidly. Refactoring is an ideal solution if keeping pace with rapidly shifting tech is integral to a company's future or certain workloads.
Ten Best Practices To Ensure A Successful Migration Strategy
There are many parties involved in creating a successful cloud migration plan, including business units, executives, developers, engineers, and IT administrators.Furthermore, tailoring this strategy to an organization's business goals and requirements should also be paramount in its design.
Below are a few recommended practices you can use to design a successful migration strategy plan:
Define Goals
Your organization's business goals are important, and cloud migration should help achieve them. A roadmap stipulating your migration strategy with timelines, goals and milestones should ensure a smooth migration into the cloud and identify potential problems.
Furthermore, all parties involved in its implementation should be fully aware and aligned with desired results of migration - formalizing objectives with baseline measurements, key performance indicators, and progress tracking are vital to its success.
Prioritize Migration
According to your business requirements, level of complexity and risk, select which apps and services should be migrated first.
Low-impact workloads, such as those not needing significant reworking, should be moved first to reduce costs associated with costly rework projects. It is wise to create a staged plan focusing on one application or sector at a time to minimize risk and interruption.
Analyze the current IT systems and infrastructure. Use cloud native technologies when possible for app deployment in the cloud and include decommissioning plans when assets that will be transferred are complete.
Use Pricing Calculators
Cloud suppliers typically provide price estimators for their services to assist businesses in avoiding unexpected expenses related to cloud migrations.
Calculators, such as Amazon AWS' pricing calculator, may help businesses avoid unexpected expenses concerning cloud migrations by providing accurate cost estimates and recommendations regarding optimal cloud configurations. In turn, cloud migration teams can use these calculators for precise cost estimation and forecast how expenses might change as their businesses expand to help avoid unexpected expenses.
A Disaster Recovery Plan (DRP)
As part of any migration, it is imperative to have an effective disaster recovery strategy in place. Installing data backup solutions will ensure company continuity.
Your plan should include a resource allocation strategy and procedures for resuming service in case of interruption; then, update and test regularly to guarantee your DRP is free from errors and unanticipated downtimes.
All employees should Be Trained
IT personnel and employees must receive proper cloud management training. Migration strategies must account for the time and money needed for ongoing cloud training to adopt it successfully; training must include specific cloud providers and updates.
Avoid Vendor Lock-In
To prevent being locked into one vendor, your business must select the cloud provider that best meets its needs and budget.
Consider pricing, scalability, reliability and security before settling on one provider - multi-cloud can help avoid these pitfalls by offering different features from various vendors.
Measure Migration Success With A Test
Include a test plan in your cloud migration strategy for optimal transition results and minimizing risks. A trial migration will help assess whether or not you are ready for production transfer, with all applications and services functioning smoothly on the cloud as planned, KPIs being set up to determine the short and longer-term success of cloud migration technical indicators or business, with costs determined through regular evaluation of KPIs.
Regular reviews must replace these KPIs to monitor migration progress and the need for ongoing investments.
Monitoring Performance And Security
Performance and security in cloud systems should be continuously assessed. Conduct regular evaluations of application functionality while giving security measures a priority.
AWS CloudTrail and AWS CloudWatch can help to audit compliance auditors. Throughout your journey, document plans for training and testing; goals; resources; workload migration tactics; and cost analyses with stakeholders or auditors as a resource.
Automation Is The Focus
Automation is key for streamlining cloud migrations, minimizing errors, improving workflows, decreasing downtime, and cutting expenses.
Middleware such as Continuous Integration or Continuous Delivery procedures may help automate tasks to help adjust to changing cloud environments easily; AWS CloudFormation offers one such technology, which offers infrastructure as code with automated resource provisioning capabilities.
Keep Up With The Latest Updates
Stay abreast of the newest features and improvements cloud service providers provide to ensure your business can take full advantage of virtualization sandbox cloud computing.
Include an upgrade cycle in your migration strategy to ensure future-proofing and taking full advantage of any new features as they emerge; using best practices will help create a cloud migration checklist with minimal risk, disruption, and expense.
