What is application modernisation and why is it necessary?

Updated: Sep 30

The systems that we work on are constantly evolving. As technology progresses, every application will eventually reach a point where it is unable to function as it once did. These outdated ‘legacy’ systems need to be brought into the future to be able to work properly — the process of doing so is called application modernisation.


As businesses increasingly turn towards the cloud, keeping up to a modern, adaptable standard is incredibly important. Making sure your applications are up to date means that they will be compatible with newer modern features and conventions, whilst also minimising security flaws and vulnerabilities. 


We believe that application modernisation should be as simple as possible. Microsoft Azure makes it easier than ever to make sure that your systems are up-to-date, and there’s never been a better time for moving your systems onto the cloud.


So, let’s take a closer look at what application modernisation is, why you might need it, and how we can help you use it to bring your company into the future!


What Is Application Modernisation?


Application modernisation is essentially the way to make sure that your applications and systems are up-to-date with modern technology. By updating legacy apps and making sure that they can operate functionally well in modern systems, you can easily bring a host of modern features and security improvements to your organisation!


The modernisation process often involves updating ‘monolithic’ systems — systems where key functions are all in one central unit — to ‘microservices’. Microservices essentially break the system down into separate units, to make administering each unit easier.


Monolithic systems work on putting everything into a central server, and so to edit anything inside that server will mean working into the whole system, rather than an isolated unit. 


Why Do Businesses Modernise Legacy Applications? While this type of unification may seem good on paper — after all, keeping your system within one directory is much easier to handle — there are many flaws with this system:

  • Difficulty to scale effectively: Legacy monolith applications lack the flexibility to scale effectively. Businesses can’t adjust features to suit their ever-changing needs — and can’t independently scale resources as they could in a cloud deployment.

  • Complexity: In monolithic systems, back-end and front-end code are tightly integrated. That makes updating and maintaining applications difficult - as services cannot be separated and deployed independently.

  • Compatibility: To be able to receive new updates and be compatible with newer technologies, a system needs to be updated to the current standard. Monolithic systems are much harder to keep updated due to having to rewrite the whole program each time you want to upgrade any part of it, whereas microservices can be updated independently.

How Are Businesses Utilising Application Modernisation Today?

In today’s digital landscape, many businesses prefer to migrate their enterprise applications to a cloud-based solution. There are many benefits to this that make the transition appealing, a few of them being: 

  • The ability to work remotely

  • Better security features

  • Being constantly updated 

And, companies are making it super easy to do so. Especially with the assistance of Managed Service Providers (MSPs) to handle the technical stuff, Microsoft Azure makes application modernisation simple and incredibly appealing to businesses wanting to make a move into the future of technology. 

So, for most companies, there’s no real reason not to make the move over. The monolithic infrastructure isn’t really beneficial, as — especially with the support of a knowledgeable MSP  — most experts won’t find navigating and updating microservices any more difficult.

Plus, application modernisation means that investing in microservices now is a form of futureproofing your business as the world becomes more and more integrated.

How Can We Help You Get Started With Application Modernisation Right Now?


Legacy applications hold back modern businesses. Monoliths that are difficult to break up make it near impossible to add new features and scale your enterprise applications effectively. 


That’s why we recommend transitioning your system architecture to the microservices approach. With our help, we make sure to make every step of bringing your organisation to the next level as easy as possible. 


We offer expert support with application modernisation, to help make the move to a Microsoft Azure cloud-based system as effortless as possible.


We strive to make every part of the transition smooth and effortless for you.  From before, with a detailed and structured roadmap to make sure the transition is perfect — to after, with the ability to segue into post-migration management. 


That way you can focus on your organisation without having to worry about the technical stuff, while we make sure everything is taken care of for you.


Make The Move to The Future With an MSP


Application modernisation is incredibly important and beneficial to any company that wants to keep up to date in the virtual age. The reign of the large monolithic program is over, as more companies opt for microservices.


There’s never been a better time to make a move over to a modern, cloud-based system. With an MSP, you can make sure that the transition over to Azure is smooth and easy.
