Choosing an App Modernisation Strategy: The Benefits of Rearchitecting

TTD IMAGE 44 (1)

Many people believe that app modernisation simply involves migrating applications to the cloud, perhaps adding a few features or reworking the user experience on the way. If you’re looking for a quick fix or just interested in making the first step to the cloud, then this might be the right app modernisation strategy for you. But a simple approach like this could cause you to miss out on significant efficiency and productivity gains, as well as mobile working and digital innovation possibilities.

When planning your cloud migration, there are three levels of app modernisation strategy to choose from: rehosting, refactoring and rearchitecting. In this post, we explain why rearchitecting your core business apps will allow you to achieve real business value from your cloud migration. If you want to maximise your investment in cloud technology, keep reading.

Choosing the right app modernisation strategy

There are many ways to approach an app modernisation strategy, and each has benefits and downsides. The options available tend to be grouped into three: rehosting, refactoring or rearchitecting. Let’s take a look.

  • Rehosting – Also known as ‘lift and shift’, this involves taking your on-premises applications and migrating them without any structural changes.
  • Refactoring – Going further than ‘lift and shift’, refactoring involves the modification of your applications as they are migrated to the cloud, usually to take advantage of some of the native cloud services offered by the vendor. For instance, you might replace the use of a physical SQL Server with Azure SQL.
  • Rearchitecting – The only true app modernisation option; rearchitecting involves renovating or rebuilding your apps in the cloud. This method allows you to enjoy the full benefits of cloud computing.

Choosing the right method for you will depend on a variety of factors. There’s a lot to be considered, but we can break it down this way:

  • If you just want a quick fix with minimal disruption, then rehosting might be for you.
  • If you want to take advantage of some native cloud hosted services, e.g. Azure services, then you may want to refactor.
  • If you are looking to completely modernise not just your core apps but your processes too, in order to facilitate modern ways of working, then rearchitecting is for you.

Rearchitect your core apps for cloud success

First, let’s tackle the limitations of the first two methods: rehosting and refactoring.

The problem here is that you only ever get so much back from your investment. For some organisations, this can be the right solution in the short term. But if you are looking for long term benefits of a modern workplace, you need to go further.

The cloud brings with it a whole host of benefits:

  • Control over costs
  • Robust security
  • Improved mobility
  • Flexibility and agility
  • Scalability costs

The goal of a cloud migration should be to unlock these benefits for your business and a quick lift and shift migration won’t allow you to fully do so. You might see security benefits, for instance, greater mobility and some control over costs. But you won’t be able to on the scale required to be truly competitive in the modern world. To fully future-proof your business and set up for future growth, you need to invest in architecture.

There’s another incentive too: keeping up with the competition. Your competitors are likely to be moving to the cloud, if they haven’t already. What’s more, businesses everywhere are racing to take advantage of emerging technologies, such as machine learning. To set your business up to be able to do the same, you need to be in the cloud. If you don’t make the same investment in app modernisation today, you risk falling behind in the long term.
