What is application modernisation?
Application modernisation is the practice of updating older software for newer computing approaches, including newer languages, frameworks and infrastructure platforms. It is the software development equivalent of renovating an older home to take advantage of improvements in efficiency, safety and structural integrity. Rather than retiring an existing system or replacing it wholesale, legacy modernisation extends the lifespan of an organisation’s applications while also taking advantage of technical innovations.
Why should businesses modernise legacy applications?
It makes smart business sense for organisations to modernise legacy applications because it (1) extends the life of current applications; (2) takes advantage of innovations in computing technology; and (3) extends the value of legacy applications.
It makes sound financial sense to modernise applications because companies often have significant financial resources invested in their current technology framework and a bottom-to-top rebuild of their core services and infrastructure may be cost-prohibitive. Application modernisation allows a business to renew, restore and revitalise computing technology, similar to the way you might remodel a home, keeping the “bones” of the home while updating those aspects that can be modernised.
It makes sound workflow sense because modern application computing architecture is faster, more efficient and more powerful. Organisations may see productivity improvements through shortened compute and process times. Businesses may also see more efficient employee workflows from the switch to cloud-based computing, which can shorten the time and distance between prompt and response.
How do businesses modernise legacy applications?
Businesses can modernise legacy applications in multiple ways:
This is the most time-consuming, risky and expensive option. It involves taking all monolithic applications and computing architecture, and replacing them with modern technology. Not only is this expensive, but at scale this would almost guarantee downtime during the transition process. Critical infrastructure would be non-existent and many internal and consumer-facing processes would be at a standstill.
Another option is to replace monolithic services with modernised microservices that can adopt computing responsibilities. This could be a simpler, more cost-effective option, since application components are decoupled and no longer bundled together.
An organisation may also move in part or whole from physical on-prem servers to cloud-based compute solutions. Even if they are not ready to commit to a full-cloud architecture, some of the computing workload can be handled cloud-side, removing the burden from physical, potentially outdated local hardware.
Lift and shift
Lift and shift, also known as rehosting, involves taking an application “as is” and moving it completely from a legacy environment to a new infrastructure, such as a public cloud platform. This is the least intensive approach, but it might not be the best one depending on the application.
Refactoring involves taking a legacy application and rewriting significant amounts of the underlying code to better run in a new environment, such as a cloud infrastructure. This approach is typically used when an application is broken up into decoupled pieces, called microservices.
Replatforming does not require major code changes but utilises complementary updates, such as modifying a back-end database, to allow the application to take advantage of a modern cloud platform.
Why do enterprises need application modernisation?
Application modernisation is important for small to medium-sized businesses, but it’s critical for enterprise organisations. Generally speaking, application modernisation is a means of future-proofing an enterprise, readying it for both market and technology disruptions that will inevitably change the course of computing. This adaptability is vital to long-term viability.
More specifically, enterprises need application modernisation for the following reasons.
Transition to cloud architecture
Enterprises can use application modernisation as the catalyst for transitioning to the cloud. Such a transition provides the many benefits of cloud-based computing, such as on-demand resource allocation, self-service provisioning, a global presence and usage-based pricing.
As the speed of business increases, enterprises must be nimble and agile as they deliver products and solutions to a customer base accustomed to on-demand timelines.
Preserve and maximise investment in legacy/monolithic computing
Rather than replace legacy applications, enterprises can preserve and maximise their initial investment by modernisation, protecting the bottom line and communicating soundness to shareholders.
Security and compliance
As the value of data increases, so does the value of securing that data and ensuring full compliance with data protection and storage requirements. Enterprises that modernise their applications are in a better position to mitigate risk and avoid breaches that could jeopardise their standing with shareholders and customers globally.
HPE and application modernisation
Enterprise IT organisations are adopting and integrating containers based on the needs of their business. Yet they are also making implementation decisions based on their familiarity with container technology. Regardless of where a business is on its containerisation journey, HPE can help.
HPE Ezmeral Runtime Enterprise is the industry’s first enterprise-grade container orchestration platform designed to run modern applications (both cloud-native and non-cloud-native) with persistent data. HPE Ezmeral Runtime Enterprise deploys 100% open-source Kubernetes for orchestration, provides a state-of-the-art file system and data fabric for persistent container storage and provides enterprises with the ability to deploy non-cloud-native AI and analytics workloads in containers.
HPE and data-first modernisation shift the focus from infrastructure-centric transformation to data-centric value creation and elevate data as the pre-eminent organising principal of a company.
The approach behind data-first modernisation is to get every department in your organisation (IT and beyond) to ensure the accessibility of data regardless of where it resides and to eliminate data silos proactively. This way of thinking unleashes data as a lifeforce for your company to create rich experiences, accelerate decision velocity and deliver continuous innovation to move your business forward.
The HPE GreenLake edge-to-cloud platform powers data-first modernisation to fast-forward your digital transformation, from edge to data centre to cloud. HPE brings a unified cloud experience to apps and data everywhere, eliminating data silos across multi-gen IT, ensuring data accessibility – wherever the data resides – and unleashing data as a lifeforce for your company to create rich experiences, accelerate decision velocity and deliver continuous innovation to move your business forward, faster.
