- Improved Security: Popular cloud services employ adequate security features such as firewalls and encryption and adhere to industry standards, leading to enhanced security levels compared to conventional solutions offered in the market.
- Scalability: Cloud services offer on-demand scalability, which makes it easier for organizations to scale up depending on current circumstances. This flexibility helps organizations adapt to workload fluctuations without investing in extra capacity.
- Enhanced Accessibility: A cloud-based system provides access to data and applications anywhere with an internet connection. This increased access has helped facilitate remote working, enhanced collaboration, and ensured business continuity.
- Increased Agility: Cloud migration helps organizations quickly roll out new applications and services. It assists organizations in responding to new changes, integrating new approaches, and enhancing their pace of digital transformation.
Types of Cloud Migration

There are several types of cloud migration, each catering to different needs and strategies depending on an organization’s goals, current IT landscape, and future requirements.
1. Rehosting (Lift and Shift)
Rehosting involves transferring data and applications to the cloud with limited or no changes. It is also referred to as ‘lift and shift,’ and it is the fastest approach as it simply involves making a clone of the existing infrastructure in the cloud.
This is ideal for organizations that need a quick migration solution without much complication. However, it does not fully exploit the optimal advantages of cloud computing, such as performance optimization and scalability.
2. Refactoring (Rearchitecting)
The refactoring approach entails many changes to the applications to enable them to run in the cloud environment.
This might include decomposing a monolithic application into microservices or refactoring portions of the application to incorporate various cloud-native services such as serverless computing or managed databases.
Although refactoring requires more time and effort, it maximizes all the advantages of cloud computing, including business continuity and costs.
3. Replatforming
Known also as “lift, tinker, and shift,” this approach is between rehosting and refactoring. It requires slight modifications to a cloud application without significantly changing it.
Replatforming is a middle ground between rehosting, which is easier, and refactoring, which offers improved performance.
4. Repurchasing
Organizations might decide to replace their current applications with cloud-based SaaS (software-as-a-service) solutions in this scenario. This type of migration is often used when legacy systems no longer meet business requirements, and it can be more cost-effective to adopt new SaaS applications rather than migrate existing ones.
5. Retiring
Some applications may be considered unnecessary or redundant during the migration process. Retiring involves decommissioning these applications, freeing up resources, and reducing the complexity of the overall migration effort.
6. Retaining (Hybrid Migration)
Some organizations keep some essential applications on-premises for regulatory, security, or performance reasons while migrating others to the cloud. This hybrid approach allows businesses to benefit from the cloud while controlling specific on-premises systems.
8 Key Components of Cloud Migration Checklist
Ensuring a smooth transition to the cloud requires careful planning and attention to detail. Here are the 8 critical components of a cloud migration checklist that can help guide your organization through the process.
1. Define Your Migration Goals
It is crucial to clearly determine your goals before you begin a cloud migration process. The reasons your organization is adopting the cloud will dictate the whole process of migration.
An optimized application migration checklist helps in making sure that every aspect is thoroughly handled.
Common goals include:
- Cost Reduction: Reducing the expense of Information Technology by using a cloud platform.
- Scalability: Improving the flexibility of resources in terms of scaling up or down on the basis of demand.
- Performance: Enhancing the system functionality and interacting with the end users.
- Disaster Recovery: Investing in improved data backup and disaster recovery solutions.
- Innovation: Enabling the faster deployment of new applications and services.
2. Assess Current Infrastructure

The first step is to make a careful and detailed evaluation of the existing IT environment. This involves:
- Inventory: Listing of all applications, databases, servers, and network entities.
- Dependencies: Determining interdependencies between applications and services.
- Performance Metrics: Collection of performance data to understand current workloads.
- Security: Reviewing security arrangements and legal standards.
3. Choose the Right Cloud Model
Choosing the suitable cloud model is a strategic decision that determines the whole migration process. The main cloud models include:
- Public Cloud: Resources are owned and are provisioned by third-party cloud service providers.
- Private Cloud: Resources are used exclusively by a single organization, either on-premises or hosted by a service provider.
- Hybrid Cloud: Connects public and private clouds so users can transfer data and applications between these clouds.
- Multi-Cloud: Implements solutions and services of more than one cloud computing supplier to prevent dependency on a sole supplier.
4. Develop a Migration Plan
A migration plan for each application is helpful because it lays down a map of the process. Critical elements of a migration plan include:
- Timeline: The expectations for each phase of the migration have to be reasonable and realistic.
- Resources: It involves identifying and mobilizing the available human and financial resources.
- Prioritization: Deciding which application and services are to be migrated according to the sequence.
- Testing: Considering pre-migration, migration, and post-migration testing strategies.
5. Select a Cloud Service Provider
