Rehosting Vs. Replatforming: Which Is Right for You?

When migrating to the cloud, you face a critical decision: take the fast lane with rehosting, which quickly gets your legacy systems up and running, or undertake a transformative journey with replatforming, which rebuilds your applications from the ground up, releasing unprecedented agility and scalability. Rehosting is quick and cost-effective, but it might not fully leverage cloud-native features. Replatforming requires significant investment, but it can revolutionise your business. Assess your organisation’s readiness, weigh costs, and ponder long-term strategy before making a move. There’s more to ponder – and discover – on this journey to the cloud.

Key Takeaways

• Rehosting is ideal for quick migration to the cloud with minimal changes, maintaining legacy system familiarity.• Replatforming transforms legacy systems, leveraging cutting-edge cloud-native features for unprecedented agility and scalability.• Assess your organisation’s IT maturity, change management capabilities, and readiness for transformation before replatforming.• Weigh the costs and resource allocation for replatforming against its long-term benefits, such as increased agility and scalability.• Consider your business goals and prioritise a long-term strategy for scalability, flexibility, and innovation when choosing between rehosting and replatforming.

Understanding Rehosting Benefits and Drawbacks

When you’re considering rehosting, you’re basically lifting and shifting your application to a new cloud provider, which can be a great way to breathe new life into your legacy system without fully rebuilding it.

This approach allows you to take advantage of cloud agility, which means you can quickly scale up or down to meet changing business demands. Rehosting also enables you to modernise your legacy system, giving it a fresh new look and feel without having to rip and replace the entire system.

One of the biggest benefits of rehosting is that it’s relatively fast and easy to do. You’re not rewriting code or making significant changes to your application, so you can get up and running in the cloud quickly.

This approach also tends to be less expensive than replatforming, which can be a major cost savings. Additionally, rehosting allows you to maintain the familiarity of your legacy system, which can be a big plus for your users.

However, rehosting isn’t without its drawbacks. Because you’re not making significant changes to your application, you may not be taking full advantage of cloud-native features and functionality.

You may also be limited by the constraints of your legacy system, which can hold you back from achieving true cloud agility. Despite these limitations, rehosting can be a great option for organisations looking to dip their toes into the cloud without fully committing to a full-scale replatforming effort.

Replatforming: a Deeper Dive Into Complexity

Replatforming takes your legacy system on a transformative journey, where you’re not just shifting to the cloud, but rebuilding your application from the ground up, leveraging cutting-edge cloud-native features and functionality to harness unprecedented agility and scalability.

This journey isn’t for the faint of heart, as it requires a significant investment of time, resources, and effort. But the payoff can be substantial, allowing you to shed technical debt and tap into new levels of innovation and competitiveness.

As you replatform, you’ll need to tackle the technical complexities of rebuilding your application, which can be intimidating. You’ll need to reassess your architecture, re-architect your database, and re-engineer your codebase.

But it’s not just about the tech – replatforming also requires a cultural shift within your organisation. You’ll need to adopt a cloud-native mindset, embracing DevOps principles, agile methodologies, and continuous integration and delivery.

This shift can be challenging, but achieving success is critical to harnessing the full potential of the cloud. By replatforming, you’re not just modernising your application – you’re modernising your organisation.

You’re creating a culture that’s agile, adaptable, and innovative, with the ability to respond quickly to changing market conditions. So, if you’re ready to take the leap and transform your organisation, replatforming might be the right choice for you.

Assessing Your Organisation’s Readiness

As you prepare to take the leap into replatforming, you’ll need to take a hard look at your organisation’s ability to adapt and evolve.

This introspection is vital, as replatforming is a complex process that requires significant changes to your IT infrastructure and operations. To succeed, you’ll need to assess your organisation’s readiness for this transformation.

Start by evaluating your organisation’s IT maturity.

Are your IT systems and processes well-documented, standardised, and optimised? Or are they fragmented, inefficient, and prone to errors? A high level of IT maturity is essential for replatforming, as it enables you to adapt quickly to changing requirements and minimise disruptions.

Next, consider your organisation’s change management capabilities.

Do you have a structured approach to managing change, or do changes often get pushed through without proper planning and communication? Effective change management is vital for replatforming, as it confirms that stakeholders are informed, trained, and alined with the new platform.

Weighing Costs and Resource Allocation

By committing to replatforming, you’re about to undertake a costly and resource-intensive journey, so venture wisely against the potential benefits and allocate resources judiciously to maximise ROI.

It’s essential to weigh the costs and resource allocation carefully, as replatforming can be a significant undertaking.

You’ll need to set clear budget priorities, identifying areas where you can optimise resource utilisation and minimise waste.

This might involve reassigning personnel, renegotiating contracts, or even bringing in external expertise to supplement your team.

Resource optimisation is key to ensuring that your replatforming efforts remain on track and within budget.

This means streamlining processes, automating where possible, and leveraging tools that can help you manage your resources more efficiently.

As you weigh the costs and allocate resources, consider the long-term benefits of replatforming.

Will the increased agility and scalability ultimately lead to higher revenue and growth?

Will the improved customer experience result in increased loyalty and retention?

Long-Term Strategy and Scalability

Crafting a long-term strategy that alines with your business goals is essential, since you’ll want to make certain your new platform can scale seamlessly to accommodate your growing customer base and evolving product offerings. You don’t want to find yourself stuck with a platform that can’t keep up with your business’s rapid growth.

When it comes to long-term strategy, you’ll need to evaluate cloud flexibility. You want a platform that can adapt to changing business needs, and cloud flexibility allows you to scale up or down as needed. This facilitates that your platform remains agile and responsive to shifting market conditions. In other words, cloud flexibility gives you the freedom to pivot quickly in response to new opportunities or challenges.

Business agility is also pivotal in your long-term strategy. You need to be able to respond quickly to changing customer needs, and a platform that’s overly rigid or inflexible will hold you back. By choosing a platform that’s designed for business agility, you’ll be able to innovate faster, experiment with new ideas, and stay ahead of the competition. Remember, your platform should be a catalyst for growth, not a hindrance. By prioritising long-term strategy and scalability, you’ll be well on your way to building a platform that drives business success.

Conclusion

You’ve navigated the rehosting vs. replatforming maze, and now it’s time to make a move.

Think of your decision like choosing the right gear for a bike ride – rehosting is like shifting into a higher gear, while replatforming is like swapping out the entire bike.

Which one is right for you? The answer depends on your organisation’s unique landscape.

Take a deep breath, assess your needs, and pedal forward with confidence.
