Kubernetes challenges

According to CNCF’s Cloud Native Landscape, there are more than 109 tools to manage containers, but 89% are using different forms of Kubernetes. This is an increase from 83% using different forms of Kubernetes in 2018. The top 10 tools are:

What are the main challenges in using/deploying containers?

Cultural challenges with the development team remain the top challenge in using/deploying containers (43%). Security (40%) and complexity (38%) remained high on the list. Lack of training, which was at 40% last year, saw a drop of 15% this year as more training options became available. Monitoring again closed out the top five (32%). Service mesh was added this year as a new response and was selected by 26% of respondents.

Security was cited by 46 percent of Kubernetes users,twenty-three percent said scaling deployments based on load is a challenge. This likely means that many requirements have been met, with Kubernetes actually helping with scaling as it is supposed to do. At the bottom of the list, 10 percent mentioned problems getting vendor support. 

Going live with Kubernetes is one thing; managing it is another. Kubernetes management is a largely manual exercise because all you get with Kubernetes is Kubernetes. The platform doesn't come with anything to run it, so you need to figure out how to deliver resources to Kubernetes itself—no easy feat.

When it comes to serving the needs of the enterprise, you'll need to security harden Kubernetes and integrate it with your existing infrastructure. Besides handling upgrades, patches, and other infrastructure-specific management tasks, you'll need the right knowledge, expertise, processes, and tools to operate and scale Kubernetes effectively.

As the organization size grows there are more challenges. 55 percent of organizations with 1,000 or more employees said security is a challenge, while only 39 percent of organizations with fewer than 100 employees said the same.For organizations only using containers on a public cloud, monitoring and logging were more often cited as a challenge

Conclusion:

Look at the above challenges as areas of opportunities where you can invest your time and efforts to solve some of these challenges to build your brand as a developer,architect or freelancer in container technologies.
