Application modernization: how Creditas advances in its Cloud Native journey

Reducing operational costs, increasing agility in deploying new projects, and improving customer experience are some of the advantages that justify the modernization of applications by companies seeking to stand out in the digital environment.

However, the transition to cloud computing does not happen overnight. It is a journey that involves a series of considerations, such as the level of criticality of applications, company culture, business goals, agreement between the company's departments, financial availability, and workforce qualification to operate in the new environment.

Kubernetes, the key to application modernization

Once these issues are settled, Kubernetes, an open-source technology for orchestrating containerized applications, is a strategic cornerstone for companies to achieve high standards of efficiency through application modernization.

The benefits of the platform—such as standardizing infrastructure usage to support multi-cloud strategies, a high level of automation for unparalleled operational efficiency, a self-service infrastructure format that allows more agility and autonomy for development teams, more efficient consumption of infrastructure leading to cost savings, and the easy ability to scale to match service user growth or seasonal peaks—make it the right choice.

To understand how Creditas, a unicorn secured-lending fintech and client of Getup, works on its modernization journey, we spoke with André Luiz Bernardino, Engineering VP of the company. The leader commented that u201c95% of Creditas' applications are in containers and 80% of them run on Kubernetesu201d. Despite almost all of them being in cloud computing, due to criticality, the fintech keeps 5% running on virtual instances in AWS. However, these are in the process of migrating to containers as well. Application modernization is a reality at Creditas, but Andru00e9 understands that getting corporate buy-in is still a major challenge for most companies. Even though the gains with Kubernetesu2014such as lower mean time to recover systems, agility in deploys, increased autonomy and productivity for development teams, and fewer incidentsu2014justify its adoption, there is difficulty in making them tangible in business revenue in the short term. Once modern technologies are adopted, the leader believes they are attractive for retaining and hiring new talent. This is the case for Creditas, which has more than 600 professionals in the Technology area, 20 of whom work as SREs with deep knowledge of Kubernetes. With a highly qualified team to manage the complexity required by modern applications, Creditas relies on Getup's support to remotely run and monitor its Kubernetes clusters hosted in GCP 24 hours a day, 7 days a week. u201cOur team is very experienced, but we have few professionals with GCP experience. Having Getup's support makes it easier to scale the team to meet our sustainability needs without having to hire new professionals internally,u201d concludes Andru00e9.
