Leumi Group Accelerates and Simplifies Migration to the Cloud Using HAQM EKS Anywhere

Leumi is Israel’s oldest banking corporation, delivering digital products and banking services to individuals, small-to-medium enterprises, and large corporations. To fulfill its strategic objective to create a technological environment that increases business performance and customer service, Leumi also runs a technology company called FinTeka. FinTeka provides financial technology (fintech) startups with access to Leumi’s open banking operations, infrastructure, and capabilities, which they can use to develop financial solutions that Leumi can, later on, deploy to its customers.

Leumi’s cloud-first strategy aims to accommodate startups by meeting them in their chosen cloud environment—which, for most, is AWS. Leumi dictates that every new project be examined as a candidate for cloud deployment. “On the cloud, we can move fast, just like startups,” says Moti Levi, manager of the Cloud Center of Excellence (CCoE) team at Leumi. “These fintech companies integrate with Leumi—which has a huge amount of data, experience, and knowledge that can drive them forward—while using their preferred cloud technologies.” However, Leumi’s hybrid environment meant that it also needed the technologies and capabilities for cloud-native workloads within its on-premises infrastructure. The bank is planning to migrate fully to the cloud in the future; because HAQM EKS and HAQM EKS Anywhere are supported by the same technology, it can transition from on-premises to the cloud with reduced risk. It will need to maintain a hybrid environment over several years as it migrates data to the cloud.

In 2017, Leumi started developing workloads based on the microservices paradigm and deployed them on virtual machines, and then on another Kubernetes solution that eventually reached its end of life. At that point, Leumi chose to migrate to the cloud and searched for a Kubernetes-conformant option that was consistent with HAQM EKS. It found that solution in HAQM EKS Anywhere. Despite having used other cloud providers, Leumi chose to go all in on AWS. “If we took more than one cloud provider, we would never be as professional or as detail-oriented or make the best of the cloud,” says Levi. “AWS was a better fit and had experience serving our industry.”

In just 5 months, Leumi migrated 16 on-premises applications from its former Kubernetes solution to HAQM EKS Anywhere with no service interruptions. The transition and management of Leumi’s products and services are transparent and simpler than running two Kubernetes clusters on the cloud. Because it hosts both its cloud and on-premises clusters on AWS, Leumi can also access the same level of support from the AWS team, further simplifying Kubernetes management across its environments. “HAQM EKS Anywhere made what could have been a complex migration very simple,” says Levi. Most of the bank’s Kubernetes workflows are already running on HAQM EKS Anywhere; its next step will be to migrate the applicable services to HAQM EKS in the appropriate AWS Region, a physical location around the world where AWS clusters data centers. “Because HAQM EKS Anywhere offers a Kubernetes distribution that is consistent with and as reliable as HAQM EKS, we can first migrate our products and services to an on-premises solution and use it as a stepping stone to migrate to the cloud,” says Levi. “We don’t lose anything. We only gain big value resulting from efficiencies of scale.”

Using HAQM EKS Anywhere, Leumi doesn’t have to modify its products to migrate them to the cloud. “Because we use HAQM EKS, not a lot has changed for our developers,” says Levi. “The code is the same code, and the containers are the same containers.” Now, developers have access to a control plane that supports them in migrating to HAQM EKS Anywhere in just 1 week. On AWS, Leumi has the agility to improve collaboration with fintech companies. In 1 hour, the CCoE team can deploy a new environment for a proof of concept with a third party, which previously would have taken weeks, and they can use management tools included in HAQM EKS Anywhere. The option to purchase one-stop support from AWS for its HAQM EKS Anywhere clusters also simplified the support process, providing a unified experience across Leumi’s cloud and hybrid Kubernetes environments, which are fully powered by AWS.

Because HAQM EKS is a managed service, Leumi’s developers can focus on business logic rather than infrastructure maintenance, which accelerates time to market and helps maintain high security. Implementing and operating HAQM EKS Anywhere was native to the bank’s operations teams, therefore reducing the risk of operating new technology. Applications can run agnostically either on HAQM EKS on the cloud or HAQM EKS Anywhere on premises, improving developer agility. Developers can get to work faster and take advantage of cluster pricing on HAQM EKS Anywhere, which has unlocked key benefits for Leumi. “Using HAQM EKS and HAQM EKS Anywhere, we save time and money and maintain the stability of the production environment,” says Levi. Leumi has used its new infrastructure for about 6 months without downtime, even when working from a secondary site.

In the future, Leumi plans to run thousands of workloads and microservices on HAQM EKS Anywhere and will introduce self-service tools so that its developers can more efficiently manage its cloud environment. The bank is also holding informal presentations for internal staff about AWS services so that they can better acclimate to the cloud.

“We appreciate the support and close engagement and assistance from AWS,” says Levi. On AWS and by using HAQM EKS Anywhere in particular, Leumi is meeting its mission of conducting proactive, innovative banking for customers.
