The Hype vs. The Reality of Containers
Enterprises love the idea of containers. Faster deployments, better resource utilization, and seamless portability make them an attractive alternative to traditional application hosting models. However, despite widespread enthusiasm, full-scale adoption remains slower than expected. Many organizations experiment with Kubernetes, only to struggle when it comes to integrating it into their existing landscapes.
The biggest misconception is that container adoption is just a technical upgrade. In reality, it requires a fundamental shift in how applications are built, deployed, and operated. Traditional IT environments were built around static infrastructure, with applications running on dedicated VMs or physical servers. Containers introduce a highly dynamic environment where workloads can be scheduled, moved, and scaled automatically. This shift is not just technological but cultural. Not only that, but you cannot just take “any old” application and run it inside a container. An application has to be specifically packaged as such, and if the application comes from a 3rd party, for supportability reasons, its that provider who needs to do the repackaging and distribution. Even for in-house built applications, the migration of the application to a container form-factor requires careful consideration and technical planning.
Key Adoption Trends
The rise of Kubernetes has driven several major shifts in enterprise IT. One of the biggest trends is the move toward cloud-native application development. Instead of simply lifting and shifting legacy applications into containers, enterprises are increasingly refactoring applications to take full advantage of containerization.
Another major shift is the expansion of Kubernetes beyond the datacenter. While early adoption focused on cloud and on-prem environments, Kubernetes is now running in factories, retail stores, and IoT deployments. The ability to manage workloads at the edge is becoming a key driver of adoption.
At the same time, standardization on Kubernetes is becoming the norm. More enterprises are adopting Kubernetes as their primary container orchestration system, moving away from proprietary solutions. This standardization is reducing fragmentation in the container ecosystem and making it easier to integrate Kubernetes across different environments.
The biggest trend however is the “rollup” of a Kubernetes adoption to also include an operational transformation to DevOps, IaC/GitOps, and in many cases, the establishment of a new Platform Engineering function.
What’s Slowing Adoption?
Despite these trends, many organizations face significant challenges in adopting containers. The skills gap is one of the biggest barriers. Kubernetes is complex, and many enterprises lack the in-house expertise needed to deploy and manage it effectively.
Operational complexity is another major hurdle. Running Kubernetes at scale requires proper governance, monitoring, and security controls. Many organizations, due to a lack of staff with experience in successful Kubernetes projects, underestimate the effort required to manage Kubernetes beyond initial deployment.
Additionally, due to the roll-up of Kubernetes adoption with a transition to DevOps, IaC/GitOps and Platform engineering, the overall scope of any “Kubernetes project” becomes a significantly larger undertaking. This makes the ROI of any proposed project more of a longer term payback vs quick gains.
Finally, legacy infrastructure remains a challenge. Most enterprises do not start with a blank slate. They have existing systems that were not designed for containerization, making migration difficult. Successful container adoption requires more than just new technology. It requires a strategy that accounts for people, processes, and integration with existing enterprise systems.
The Path Forward
Enterprises that succeed with container adoption do not just focus on technology. They invest in training, create well-defined processes, and ensure that their teams have the right tools to manage Kubernetes effectively. The organizations that treat container adoption as a long-term transformation, taking gradual steps forward rather than one giant leap, will be the ones that see the greatest benefits.
Additionally, investing in tools like Portainer that alleviate as much of the up-front complexity as possible, significantly helps to lower the barrier to entry for staff, and dramatically lowers the risk of project failures/cost over-runs.
Attempting to construct your own “perfect” Kubernetes platform, instrument a new operational paradigm, retrain all staff, and migrate all applications, as a single project, lead by a very small team, that is a recipe for disaster.
