Consol: DevOps and containers – the perfect pair

The IT service provider Consol cites four reasons why containers and DevOps together form the perfect pair. […]

Where in the past development and operation were strictly separated, today they work closely together. And although DevOps is above all a matter of corporate culture, practical implementation today is typically accompanied by the use of container technology.

Containers make it possible to isolate the application processes of a computer as if each were on its own, dedicated system. Containerization facilitates robust software operation by decoupling from the actual platform. But why is this so important, especially in the DevOps context? IT service provider Consol has four answers to this question.

1. Containers facilitate cooperation

DevOps is above all a matter of the right corporate culture and attitude in the team. However, how well the cooperation goes in day-to-day business still depends on technical details. Where in the past developer setups for testing a software, for example, had little in common with the actual production environment, containers can provide a common runtime environment setup for both. Containers are at home in both worlds, so to speak, and therefore a suitable common denominator for the quite different areas of work.

2. Containers break up silos

DevOps means that development and operation share a complex process, i.e. the creation and operation of a software artifact. Both parties must understand this life cycle holistically, because they also bear equal responsibility for it. The software artifact can represent the container or the container image on which the running containers are based. Since containers are known as tools for both development and operation, Dev and Ops gain a deeper understanding of all the workflows of a process based on this technology. This is how containers help in the dismantling of knowledge silos.

3. Containers boost automation

The improved collaboration between Dev and Ops combined with the breaking of knowledge silos opens the door for practices such as continuous delivery. This collection of techniques, processes and tools improves the delivery of software and enables a high degree of automation. Containers are unrivalled, especially for automated tests: for example, in the build-up and pull-down of complex architectures for integration and end-to-end tests.

Continuous deployment goes one step further, in which the team not only automatically delivers “deployable” software, but actually brings the software into production automatically.

4. Containers provide more security

The fewer manual steps the teams have to perform in the development process and the operation of a software, the lower the susceptibility to errors. Since containers ensure a much higher level of automation in the software life cycle, they also indirectly improve security. Thanks to automated tests that DevOps teams can integrate into the deployment and release process of applications, errors can often be found more quickly. This gives developers the opportunity to react to security vulnerabilities and bugs at very short notice – often before they get into production.

“DevOps is above all a matter of corporate culture,” emphasizes Oliver Weise, Principal Software Engineer at Consol in Munich. “Collaboration between Dev and Ops cannot be accelerated by tools alone. Nevertheless, the use of technical tools such as containers supports the transformation of the company and the practical implementation of a DevOps strategy.“Further information can be found here.
