This accessibility promotes productivity, enables seamless remote work, and simplifies sharing and real-time collaboration on projects.
- Reliability and data security – Cloud providers invest heavily in robust infrastructure and security measures to ensure high levels of reliability and data protection. They offer features such as data encryption, regular backups, disaster recovery options, and compliance certifications, providing businesses with peace of mind and reducing the risk of data loss or security breaches.
- Simplified IT management – Cloud migration reduces the burden of maintaining and managing on-premises infrastructure. The cloud provider handles tasks such as system updates, maintenance, and security patches, allowing businesses to focus more on core competencies and strategic initiatives rather than routine IT management.
So if you are up for greater flexibility, cost efficiency, scalability, and fresh innovation opportunities, you know what to turn to now. Cloud migration empowers organizations to leverage the power of cloud computing to drive digital transformation, improve agility, and stay ahead in today’s rapidly evolving business landscape.
Cloud Migration Strategies
There are different ways how businesses can move to the cloud, and each strategy is intended for different companies and cases. The below tactics provide different approaches to migrating applications, data, and infrastructure to the cloud. And we recommend that you check them all before deciding what option works best for you.
#1 – Lift and Shift (Rehosting)
This strategy involves migrating applications and data from on-premises infrastructure to the cloud with minimal modifications. It focuses on replicating the existing environment in the cloud, typically using infrastructure-as-a-service (IaaS) offerings. It offers a faster migration process but may not fully leverage cloud-native capabilities.
#2 – Replatforming (Lift, Tinker, and Shift)
With this strategy, applications are migrated to the cloud while making some optimizations to take advantage of cloud-native services. It involves making changes to the application architecture or code to adapt it to the cloud platform. Replatforming allows organizations to benefit from certain cloud capabilities but with moderate effort.
#3 – Refactoring (Re-architecting)
This strategy involves making great changes to the application architecture and code to fully leverage cloud-native features. It often involves using platform-as-a-service (PaaS) offerings and microservices architecture. Refactoring allows organizations to achieve greater scalability, flexibility, and efficiency, but it requires more time and effort compared to other strategies.
#4 – Rearchitecting for the Cloud
According to this strategy, organizations completely redesign their applications and systems to take full advantage of cloud capabilities. It involves rebuilding applications using cloud-native services and adopting modern architectural patterns, such as serverless computing or containers. Rearchitecting provides maximum scalability, resilience, and efficiency but requires a significant investment of time and resources.
#5 – Hybrid Approach
This strategy combines elements of on-premises infrastructure with cloud services. Organizations retain certain systems or applications on-premises while migrating others to the cloud. This approach allows for gradual migration, flexibility, and integration between cloud and on-premises environments.
Choosing the Right Strategy
The choice of migration strategy depends on multiple factors. Application complexity, desired cloud benefits, timeline, budget, and level of transformation required – these are just some of the things that you need to consider:
- Understand your organization’s specific needs and goals for cloud migration;
- Evaluate factors such as scalability, flexibility, cost optimization, security, and compliance;
- Assess the complexity of your applications and their dependencies on underlying infrastructure or specific software versions;
- Consider the trade-offs between effort, time, and potential benefits for each approach;
- Evaluate the amount and size of data to be migrated;
- Consider the available network bandwidth, potential bottlenecks, and the time required for data transfer;
- Choose a strategy that optimizes data transfer, minimizes downtime, and maximizes efficiency based on your data volume and transfer requirements;
