The Art of Cloud Migration: Fission Labs’ Big Three Cloud Migration Strategies

Introduction

In today's ever-evolving technological landscape, cloud migration has become a critical aspect of business transformation. For organizations looking to harness the power of the cloud, it's essential to choose the right migration strategy. We at Fission Labs, a leader in offshore software development services, understands the intricacies of cloud migration and offers three key strategies tailored to your needs: Rehost (Lift-and-Shift), Replatforming, and Refactoring. In this blog, we'll delve into Fission Labs’ Big Three Cloud Migration Strategies, each tailored to address different aspects of application optimization, complexity, and project timelines.

Fission Labs’ Cloud Migration Strategies

Rehost (Lift-and-Shift)

Pros: Accelerated migration to the cloud. 

Cons: Uses Cloud as a Hosting platform. Does not leverage any other benefits of Cloud.

In the Rehost strategy, applications are migrated to the cloud without making any changes to the core components, including the application code and database. Sometimes this approach is also referred to as“Lift and Shift” migration. However, it's critical to note that for a successful Rehost, your application code should have a certain degree of cloud alignment.

The primary advantage of Rehosting is its speed. It allows for a quick migration to the cloud, minimizing downtime. However, it merely uses the cloud as a hosting platform and may not fully exploit the cloud's capabilities.

Replatforming

Pros: Accelerated migration to the cloud with a certain level of app optimization.

Cons: Limited app performance, dependency on a single cloud provider.

Replatforming is a variation of Lift-and-Shift. In this approach, you implement cloud optimizations, primarily by utilizing managed cloud service offerings, without altering the core architecture of your application. For example, if your application uses streaming services, instead of hosting Apache Kafka on your own during redeployment, you might want to host it using Amazon Managed Streaming for Apache Kafka (AWS MSK).

This strategy offers the benefit of a relatively swift migration while achieving some level of application optimization. This approach may impact your application performance (positively or negatively) based on the configurations and availability of the service variant with the vendor, and your application strategy is prone to vendor lock-in issues.

Refactoring

Pros: Fully cloud-native, improved scalability and performance. Lesser dependency on a single cloud provider.

Cons: More complex and time-consuming.

Refactoring represents the most transformative approach. In this strategy, your application is re-architected and rebuilt with a new codebase to harness cloud-native features fully. This approach offers the potential for improved scalability, performance, and reduced dependency on a single cloud provider.

However, it's worth noting that refactoring is a more complex and time-consuming process compared to the other strategies. It requires a deep commitment to reap the full benefits of cloud-native architecture.

Fission Labs’ Cloud Migration Approach

At Fission Labs, we understand that choosing the right migration strategy is crucial for your business. Our approach to cloud migration comprises the following phases:

Assessment

Performing Application Analysis

During this phase, we delve deep into your application landscape, considering factors such as:

• Application portfolio analysis to assess cloud suitability.
• Gathering current requirements.
• Evaluation of current data architecture.
• Understanding user profiles and usage patterns.
• Ensuring compliance with security standards and regulatory requirements.
• Analyzing the current Total Cost of Ownership (TCO).

Creating Transformation Roadmap

We create a migration roadmap, a checklist, and outline success factors while identifying and mitigating risks.

Identifying Key Outputs 

Our assessment phase delivers critical outputs, including:

• Definition of the target architecture.
• Strategies for data migration and validation.
• Security and regulatory compliance measures.
• Application monitoring strategy.
• 24x7 operations processes (Op-mechs).
• TCO estimates.

Identifying Key Drivers 

Our approach is driven by key objectives:

• Reduction of TCO.
• Simplification of application architecture.
• Scalability and extensibility.
• Modernization.
• Business alignment of the technology roadmap.
• Minimizing disruption to business units.

Performing Migration Readiness Planning

We create a migration portfolio and recommend a pilot phase, typically starting with one application. This helps us refine our migration path and landing strategy.

Strategize/Redesign 

With input from your team, we design the migration platform, providing a clear project schedule and estimated timelines. This phase involves defining:

• Target architecture.
• Data migration strategy and validation plan.
• Security and regulatory compliance measures.
• Application monitoring strategy.
• 24x7 operations processes (Op-mechs).
• TCO estimates.

Implementation

Our team of architects, developers, and DevOps experts collaboratively build a robust cloud platform based on the defined strategy and architecture. 

Test & Deploy

We conduct comprehensive testing to ensure the quality of the migrated application. Once the testing phase is complete, we plan a smooth rollout to minimize disruptions.

Manage & Support

We provide ongoing support by monitoring the cloud application, ensuring its availability, responding to reported issues, and addressing your evolving requirements.
