In an era where agility, scalability, and efficiency define business success, legacy systems often stand as barriers to innovation. The migration of legacy applications to the cloud represents a strategic move to overcome these barriers, offering businesses the opportunity to modernize their IT infrastructure, enhance performance, and reduce costs.

In this comprehensive guide, we will walk you through the essentials of legacy application migration to the cloud, highlighting the critical role of managed IT services in navigating this complex process.

Understanding the Legacy Application Migration to Cloud Process

Legacy application migration to the cloud involves transferring applications, data, and workloads from older, on-premises computing platforms to modern, cloud-based infrastructure.

This process is not merely about moving to a new hosting environment; it’s a strategic transformation backed with careful planning aimed at leveraging cloud computing’s scalability, flexibility, and cost-efficiency to enhance application performance, security, and reliability.

Assessment and Planning

The first step involves a thorough assessment of the existing legacy applications to determine their suitability for cloud migration. This phase identifies dependencies, potential challenges, and the best cloud service providers for each application.

Choosing the Migration Strategy

Businesses can choose from several cloud migration strategies, such as rehosting (lift-and-shift), refactoring, rearchitecting, or rebuilding. The choice depends on the application’s complexity, the desired cloud benefits, and the available resources.

Migration Execution

This phase involves the actual moving of applications, data, and operations from the on-premises servers to the cloud environment. It requires meticulous planning to minimize downtime and ensure data integrity.

Optimization and Management

Post-migration, applications may need to be optimized for the cloud environment to fully leverage cloud resources. Ongoing management is crucial for maintaining security, performance, and cost-effectiveness for your business operations.

Why Inland Empire Businesses Are Migrating Legacy Applications to the Cloud

  • Enhanced Scalability: Cloud platforms allow businesses to scale their applications and data storage up or down based on demand, without the need for upfront investments in physical hardware.
  • Cost Reduction: Migrating to the cloud can significantly lower the total cost of ownership by reducing the need for physical data centers, lowering energy consumption, and minimizing the maintenance costs associated with legacy systems.
  • Improved Performance and Availability: Unlike outdated technology, cloud providers offer robust, distributed architecture that enhances application performance and ensures higher availability compared to traditional on-premises setups.
  • Advanced Security Features: Cloud providers provide sophisticated security features that are continually updated to protect against the latest security risks and cybersecurity threats, offering better protection for applications and data.
  • Agility and Innovation: The cloud enables businesses to deploy and test new applications quickly, providing a competitive edge by accelerating innovation and responsiveness to market changes.
  • Regulatory Compliance: Many cloud providers offer compliance solutions that help businesses meet regulatory requirements more efficiently, reducing the complexity and cost of compliance efforts.

Options for Application Cloud Migration

When considering legacy application migration to the cloud, businesses have several strategies at their disposal. Each approach offers different advantages and involves varying degrees of change to the application architecture, complexity, and cloud integration level. Here are the primary options for legacy application migration to the cloud:

1. Rehosting (Lift-and-Shift)

Rehosting involves moving an application from its current on-premises environment directly to the cloud without making significant changes to the application’s code, architecture, or features.

This approach is often the fastest and least disruptive way to migrate to the cloud, making it a popular choice for businesses looking to quickly capitalize on the cloud’s benefits without the need for extensive redevelopment.

2. Refactoring (Repackaging)

Refactoring involves making some modifications to the application’s code or configuration to fit better into a cloud environment, often to take advantage of cloud-native features and scalability.

However, the core architecture of the application remains largely unchanged. This strategy strikes a balance between leveraging cloud capabilities and minimizing the changes needed.

3. Rearchitecting

Rearchitecting means significantly altering the application’s architecture to fully embrace cloud-native technologies and practices. This approach is chosen when businesses want to add new features, scale more efficiently, or improve performance that would not be possible in the application’s existing environment. It usually involves more substantial investment but offers the most significant benefits in terms of agility, scalability, and performance in the cloud.

4. Rebuilding

Rebuilding involves completely redesigning and rewriting the application from scratch using cloud-native technologies. This option allows businesses to fully leverage the advanced capabilities of the cloud, such as serverless computing, microservices architecture, and dynamic scaling.

While rebuilding provides the most flexibility and optimization for the cloud, it also requires the most resources and time to execute.

5. Replacing

Replacing involves discarding the legacy application and replacing it with a cloud-native solution, which could be a commercially available Software as a Service (SaaS) product or a custom-built application. This approach is suitable when the existing application cannot meet the business’s evolving needs or when maintaining and migrating the legacy system is more costly than adopting a new solution.
