Created in 2014 and developed by Google, [Kubernetes](https://kubernetes.io/) is widely regarded as the go-to standard for deploying containerized applications at scale across all cloud environments. Managed by the [Cloud Native Computing Foundation (CNCF)](https://www.cncf.io/) – of which comforte AG is [a participating member](https://www.cncf.io/announcements/2020/08/18/cloud-native-computing-foundation-welcomes-new-members-during-kubecon-cloudnativecon-eu-virtual/) - Kubernetes was initially developed to be seamlessly implemented with any cloud-hosting service provider, and is already being embraced by many of the largest public cloud vendors. Additionally, organizations of all sizes are beginning to harness this technology due to its ability to deploy and manage application workloads and services at scale while ensuring applications are seamlessly running within their dedicated containers. ## The world before cloud native In the past, applications ran on physical servers which led to performance and cost issues. For instance, if a server had multiple applications running, one application could operate using more power causing other applications to underperform. To avoid this, multiple servers were created for each individual application. However, the maintenance of these servers proved extremely expensive and was not cost efficient for organizations in the long run. An alternative solution to this was virtualized deployments as these enabled organizations to run many virtual machines (VMs) on a single physical server’s CPU. They could also isolate applications to ensure one application did not interact with another – a feature that provided better security, utilization of resources and application scalability while reducing hardware costs. However, VMs run in a hypervisor environment where each virtual machine must include its own internal guest operating system, along with relevant binaries, libraries, and application files. This consumes a large amount of system resources and overhead, especially when multiple VMs are running on the same physical server, each with its own guest OS. Then came the evolution to containers, a more streamlined way to build, test, deploy and redeploy applications across multiple environments bringing greater efficiency. These provide less overhead, more portability and DevOps teams have the confidence that applications in containers will perform the same no matter where they are deployed. Moreover, containers provide improved support with the maintenance of applications throughout their entire development lifecycle. ## So where does Kubernetes come into the equation? With Kubernetes, organizations are provided with a platform that can fully manage, automate, deploy and scale applications and workloads across live environments. It can be used to support data center outsourcing, cloud/web-hosting and high-performance computing. If one container were to collapse, another would be controlled to immediately take its place. By adopting Kubernetes as the de facto standard for container orchestration, DevOps teams can accelerate all data-center orchestration and modernization efforts. Such are the benefits; many have adopted Kubernetes as a way to develop differentiated products built on cloud native foundations. ## Data security considerations for DevOps With that said, data protection and management must not be forgotten. More and more organizations are moving to the cloud with hybrid and multi-cloud strategies, which underscores the need for cloud-native applications. DevOps teams need to be as agile as possible to innovate, however traditional security architectures are often incompatible with cloud-native operational requirements, automation, languages, and orchestration frameworks such as Kubernetes. Therefore, organizations require a data security solution that is both hybrid IT and cloud-native, with full integration into auto-scaling, self-healing, metrics, logging, operation, and control via APIs in modern stacks and CI/CD pipelines. Data-centric security is the way forward for cloud security, and with more organizations adopting this approach, we will see more leverage cloud technology while keeping sensitive data safe. --- | Share this:  | [![LinkedIn](https://insights.comforte.com/hubfs/Social%20Icons/linkedin%20icon.png)](https://www.linkedin.com/shareArticle?mini=true&url=https://insights.comforte.com/why-we-use-containers-and-kubernetes-an-overview&utm_medium=social&utm_source=linkedin) | [![Bluesky](https://insights.comforte.com/hubfs/Social%20Icons/bluesky_logo.png)](https://bsky.app/intent/compose?url=https://insights.comforte.com/why-we-use-containers-and-kubernetes-an-overview&utm_medium=social&utm_source=Bluesky) | ![Twitter](https://insights.comforte.com/hubfs/Social%20Icons/twitter_x_logo-1.png) | [![XING](https://insights.comforte.com/hubfs/Social%20Icons/xing-color2.png)](https://www.xing.com/spi/shares/new?url=https://insights.comforte.com/why-we-use-containers-and-kubernetes-an-overview&utm_medium=social&utm_source=xing) | [![Email](https://insights.comforte.com/hubfs/Social%20Icons/email%20icon.png)](mailto:?subject=Check%20out%20https://insights.comforte.com/why-we-use-containers-and-kubernetes-an-overview&utm_medium=social&utm_source=email%20&body=Check%20out%20https://insights.comforte.com/why-we-use-containers-and-kubernetes-an-overview&utm_medium=social&utm_source=email) | | --- | --- | --- | --- | --- | --- | ## Secure data before it hits your cloud applications Check out the solution brief below to learn how to secure all your sensitive data intended for cloud destinations, without disrupting your business processes.
