3 COMMON CHALLENGES IN MIGRATING APPLICATIONS TO CLOUD
Moving applications to the cloud and fully digitising infrastructure is a top priority for businesses today. This comes as no surprise – cloud delivers unsurpassed speed and scalability, helping businesses to innovate fast, realise significant cost savings, and enjoy productivity gains.
What does come as a surprise to many is the degree of difficulty in migrating applications and creating, storing and managing an ever-growing array of digital solutions. A simple swan dive suddenly becomes a double somersault with a full twist
As Gartner describes, you’ve generally got five options for migrating apps to cloud. The “5 Rs” are rehosting, refactoring, revising, rebuilding, or replacing. Herein lies the first headache. The seemingly simple task of ‘moving apps to the cloud’ becomes bewildering – which option to choose for each app?
Once you’ve worked through that problem, you face two new issues: ensuring the integrity and security of your data during and after the move. According to one survey, data management is an afterthought – 54% of companies have no visibility into how data management policies are enforced, and they risk losing their data. Interestingly, in a similar survey on cloud migration, the top security concern for 57% of companies is keeping data secure.
Let’s look at each of these issues in more detail. You can dive deeper into cloud migration and how a managed, cloud-based container environment could differentiate your business in our eBook, Re-thinking digital transformation.
Issue 1. Storage – where will all the applications live?
With digital applications placing considerable demand on traditional, on-premise environments, many businesses are moving applications to cloud. Yet the lift-and-shift approach – a simplistic way of rehosting or refactoring an app– can end up costing more and taking longer. In fact, as this article states, lifting and shifting legacy apps to the cloud without expert guidance could drive up your expected cloud costs by 300%.
Containers can offer a great solution, enabling fast and consistent development and deployment of applications. Yet containers come with their own challenges – many organisations lack the skills and staff to manage a container environment internally.
Issue 2. The complexity of data integration
If you move your apps to the cloud without connecting them to compatible data sources, you can end up with fragmented silos of data across the enterprise. Think about it. If a you move mission-critical legacy ERP application to the cloud but it can’t communicate with other cloud-native apps for sales automation, human resources, or marketing – then you could end up with slower performance and a poorer user experience than if you’d left that legacy app where it was.
Often, data integration issues don’t surface until it’s too late – that is, it’s too hard to fix and you have to start again.
Issue 3. Compliance and security
As mentioned above, security is a top concern for organisations moving to cloud. Despite it being top-of-mind, many enterprises overlook the systemic changes needed for applications and
databases in the cloud to be compliant and secure. They may have manually enforced policies that are inconsistent across environments, which can carry significant risk.
Organisations need to integrate security into every aspect of planning, building and running applications – whether they are net new or modernised versions of legacy apps.
You don’t have to go it alone
While these three issues are certainly valid, don’t let them get in the way of your cloud ambitions. Moving to cloud can and will pay off if you have a solid migration strategy in place.
