Alongside a number of advantages in application lifecycle management such that Kubernetes is an environment used on a large scale, it is also important to cometo terms with one of the technology’s major limitations,security.
While we are certainly talking about a cross-cutting topic, to be considered within any new application or intervention on the IT infrastructure, it is still to be considered how in this case the responsibility, as well as the freedom of action, sis completely in the hands of the user.
The underlying principle of Kubernetes, however, is also another. In practice, it can be regarded as a kind of infrastructure within another infrastructure. Where, as a result, the level of complexity and the rate of customization are, on average, quite high. Difficult, and probably not even that useful, to hink of security settings that can meet every need. Moreover, we are still talking about a tool within the reach of figures with a good background in IT, who are aware that they have to worry about security every time new technology is introduced or changed.
In reality then, the lack of security as standard should be seen more as the freedom to optimize a platformo one’s liking. The doubt, if anything, is figuring out how to go about it and which solution to move toward to get the desired results.
To Know before you chooing
As always, excellent practice in such circumstances is to start with an assessment. That is, know in detail, needs, goals and resources. Counting on a detailed picture of one’s reality will make it easier to move through the next steps. Better still, if also relying on the outside view of a consultant specializing in the topic, possibly vendor independent.
A first item to evaluate are any existing ties where Kubernetes deployment or cloud providers are mentioned. Often, the most practical, but not necessarily the cheapest, choice is to stick tothe line nd stay in the same realm when it comes to security as well. A particularly valid consideration when it comes to OpenShift. In addition to all the relevant guarantees, Advanced Cluster Security certainly allows the service to be enabled in a Red Hat environment, reducing integration problems. Always to be evaluated with due care, however, it is one more step in the direction of an environment.
A similar argument can be made with Tanzu. VMware also developed Carbon Black with compatibility with its environment in mind first. In this case, however, the view is still broader. Indeed, the solution isalso easier to fit into different Kubernetes contexts. . Including OpenShift itself. The main limitation is the ability to operate only in the cloud and not in an on-premise context.
However, if you want the most flexibility, and in some ways the highest possible level of security, Suse NeuVector is the best solution at the moment. Again, the point of being designed to fit very seamlessly with Suse environments still applies. The level of flexibility is definitely higher.
In addition to being a module designed specifically for security in Kubernetes, it can also be considered the most comprehensive and the most mature at the moment. Important to emphasize once more, regardless of the distribution used and the cloud provider of reference. A flexibility ready to prove useful especially in case of migration
For those finally seeking maximum independence, there is one final aspect to consider. Transversal with respect to both deployment and infrastructure model, Suse NeuVector has the advantage ofbeing able to keep the entire IT infrastructure under control from a single console, regardless of complexity and deployment. It is probably not yet among the best-known alternatives in Italy, but to its advantage it should be noted that it is already widely used in the U.S. and even closer in France, Germany, and the UK.
Yet another example of how important it is to guide one’s choice without limiting oneself to one’s own knowledge. The value of an independent software systems integrator is also in the ability to analyze the market in search of innovative solutionshat meet each organization’s unique combination of technological, practical and economic requirements. Sorint.lab’s approach is to go beyond consulting, selling, and installing a solution, staying by the customer’s side even in the later stages, through training, support, and on-site interventions, combined to the customer’s measure.
