technology trend Why containers are transforming IT

Containers and microservices are on the rise. Sarah Mok, Director of SVA, knows the different aspects of the topic: from technical implementation and consequences for IT engineering in companies to a shortage of skilled workers.

Projects involving container technology in the SVA system house are diverse. They range from workshops with customers who have heard something about containers and want to know if it is a thing for them, to complex problems in which system engineers use problem solving in an existing OpenShift environment to find performance issues with a Fix of unknown origin.

Sarah Mok, Head of Business Line Agile IT & Software Development at SVA, looks back: “Container technology has been around for a long time; It has become popular since Docker made the topic as big as managing containers. “

Microservices and portability

In this sense, coordination must be understood in an automated way and that intelligence regulates the interaction of microservices. The scale is also defined, i.e. the question of when a container should be available in the number of versions. “For example, given a typical use case, when SMS service starts up on New Year’s Eve, identical containers eventually multiply,” Mück explains. The central point of container technology, which was crucial to its breakthrough, is also the issue of portability. “If a cargo ship goes down, the container can simply be loaded onto another vessel. And to maintain that metaphor: It works with everything from small fishing boats to steamers,” explains the software development expert. One of the basic ideas of containers is that you can turn them on and off at any time and no data is lost here.

Dev + Ops = DevOps

Ultimately, containers also bring together Dev themes and Ops meaning DevOps, says Mück, because projects often involve breaking monolith code into small services so that each microservice gets its own container. “The container platform, in turn, must be managed and operated by the infrastructure department.”

Skilled labor shortage in the sector

As the president, Mück knows that it is currently very difficult to find employees in this environment. “First of all, it is important to get a lot of applications and then filter them from a professional and personal point of view until we find someone who really fits the team. I think out of the 300 applicants, about ten will eventually be hired.” However, there are also many applications. Which doesn’t really fit the job, because the terminology in these niche areas often varies widely.” To give an extreme example, there were actually shipping container guards advertising our work in the Container Safety Zone,” Mück says with a smile.
