Business challenge

DTWISE needed to re-architect its software to make it easier to update, add new features and deploy. It needed a Kubernetes platform that could help it meet a tight deadline for an important customer.


DTWISE chose the IBM Cloud Kubernetes Service on IBM Cloud to transform its existing application into microservices, simplifying deployments and improving application uptime.

Business challenge story

Monolithic application poses challenges

DTWISE delivers software that helps organizations become more energy efficient. “What we do is data-driven energy efficiency,” says Spyros Tzovairis, the Chief Operating Officer and Chief Technology Officer at DTWISE. “So essentially we’re turning data into insights. And we help our customers save energy and money.” The business was growing, and it had committed to delivering a new version of its software to Elpedison, one of the three largest utility companies in Greece. DTWISE had just four months to meet this deadline.

The existing software architecture at DTWISE was causing pain points that the business needed to resolve to meet its deadline with Elpedison. “It was difficult to create new features and to expand the capabilities of our software,” says Tzovairis. “It was apparent that we had to split up the services within our monolithic software.”

DTWISE had determined that it needed to adopt a microservices-based approach to make it easier to deploy new features and support future growth more quickly. The business decided on Kubernetes so it could leverage the power of microservices while simplifying the management of services and the underlying infrastructure. But with just four months until its deadline, DTWISE needed a managed Kubernetes service that it could get up and running quickly without having to set up and maintain it themselves.

We felt confident that IBM Cloud’s scale and reputation would help us meet the contracted SLAs for our major new customer.

Transformation story

Cloud-based solution supports transformation

DTWISE chose the IBM Cloud Kubernetes Service on IBM Cloud. “We felt confident that IBM Cloud’s scale and reputation would help us meet the contracted SLAs [service level agreements] for our major new customer,” says Tzovairis.

The company worked with the IBM Cloud Services team to begin using the Kubernetes service, but then was able to quickly deploy its new containerized application to the Kubernetes service on its own. Using the Kubernetes service simplifies the management of dependencies. “You just select the right configuration once and then you don’t have to deal with it again,” says Tzovairis. “You can just rely on Kubernetes to make sure that the service that you are looking for will point to the right container. It’s very easy.”

DTWISE created a separate Kubernetes “pod,” or group of application containers, for each of its approximately 20 microservices. Because each service is deployed in its own pod, the business can update an individual service without taking down the entire application, which makes it much easier to add new features and updates. The IBM Cloud Kubernetes Service solution provides scaling functionality, so pods are automatically scaled as needed. The IBM Cloud Kubernetes Service also includes a built-in vulnerability advisor that helps the company stay on top of potential security issues. DTWISE is also using IBM Cloud Object Storage to store its application data. The business is also looking forward to using IBM Watson® for its recommendation engine, which essentially acts as an AI energy efficiency advisor.

Results story

Significant improvements to uptime

Since implementing the solution, DTWISE has improved its uptime. In fact, the business has had continuous uptime for one year. “A microservices architecture has helped us make significant improvements to uptime, which is a critical consideration for our customers,” says Tzovairis. “Since everything is in different pods, a single outage does not impact the service as a whole.” The initial deployment of the new infrastructure was very fast. “We deployed our infrastructure in a single day,” says Tzovairis. “In the past, it would have taken a week.” As it makes updates and changes to its application, the business estimates that it has reduced the amount of time needed for these types of deployments by 20 percent.

Another benefit to the solution is that it has simplified onboarding of new staff. As DTWISE continues to grow, it has been hiring new team members. “With the managed IBM Kubernetes solution, we have a much easier learning curve for our new team members, says Tzovairis. “It’s easier to understand our architecture. It’s clear to the new people what each service does and how the services work together.”
