Application modernization: soon the end of “legacy”?

Application modernization: soon the end of “legacy”? Cybersecurity

Companies have massively embraced cloud computing. Cloud services have proven themselves and demonstrated their ability to deliver digital resources in an extremely fast and agile manner. But while cloud solutions have taken up residence in information systems in recent years, the opposite is happening today.

The legacy has not given up and now intends to settle in the cloud. According to an IDC study published in August 2019, modernizing the existing has become the number 1 priority for CIOs in European companies. “The gradual transfer of applications and data to the cloud has become a recurring subject,” confirms George Anadiotis on ZDNet. And this trend will continue for at least the next ten years. “Does it signify the end of legacy in what we know?

If adopting the cloud was an obligation not to be left behind by the competition, this time “clouding” its existing is an opportunity to take a step ahead. The cloud has not negated the value of pre-cloud IT. Businesses had business and data applications long before him that already constituted a rich digital heritage. It is this heritage that must now be modernized. Objective: get the best of both worlds with internally designed applications that precisely meet business needs and a cloud foundation that guarantees agility and resilience.

Rebuild or not rebuild

Should we re-architect its application to modernize it? This is one of the first questions that will arise and one of the major obstacles to application modernization. “Depending on performance, integration, scalability or cost constraints, different strategies are open to decision-makers, from the simple change of infrastructure to the transformation of the very architecture of the application,” says the firm. IDC. However, organizations do not wish to embark on an expensive and time-consuming project whose benefits would not be felt for months, even years. If there is modernization, it must be done with the speed and agility of the cloud. In this context, companies can count on two allies: multicloud and containers.

Cloud silos have indeed started to fall in recent months, and solutions exist today to migrate virtual machines from an on-premise infrastructure to a cloud platform, and from this cloud platform to that of another supplier, without having to modify its application. The other big trend is that of containerization and microservices.

If the adoption of these recent technologies sometimes encounters a lack of skills internally, there are cloud services which allow for example to automate the creation of a Kubernetes cluster in order to offload the underlying complexity. “Our Cloud Application Platform provides the tools to deploy existing applications in different cloud environments using microservices, integrated DevOps methods, containers and the Kubernetes orchestrator,” said Franck Besnard of IBM France, who will speak on June 25 in a conference dedicated to this issue.

Security: provide safeguards

The other major challenge of modernization is obviously application security. This type of project very often concerns critical systems for the business, those whose importance for the activity justifies the resources which will be devoted to it. The priority when you want to migrate your legacy to the cloud is therefore to prepare for any eventuality.

“In a modernization process which is by definition experimental, you should be able to go back at any time,” recommends IDC. Again, the flexibility of hybrid approaches, DevSecOps methods and microservices will allow for continuous improvement processes that will ensure the success of the project, step by step.
