In Kubernetes, the task of scheduling pods to specific nodes in the cluster is handled by the kube-scheduler. The default behavior of this component is to filter nodes based on the resource requests and limits of each container in the created pod. Feasible nodes are then scored to find the best candidate for the pod placement.

Service mesh technology emerged with the popularization of microservice architectures. Because service mesh facilitates the separation of networking from the business logic, it enables you to focus on your application’s core competency.Microservice applications are distributed over multiple servers, data centers, or continents, making them highly network dependent. Service mesh manages network traffic between services by controlling traffic with routing rules and the dynamic direction of packages between services.

K8s has a built-in object (sort of) for managing network security (NetworkPolicy). While it allows the user to define the relationship between pods with ingress and egress policies, it’s still quite basic and requires very precise IP mapping - for a solution that’s constantly changing, so most users I’ve talked to are not using it. Users need a simplified solution that protects their K8s networks to the max - a solution that makes network security in K8s a do-able task with the highest security level possible: mutual TLS between microservices and real zero trust deployment. And no, this is not a sidecar solution….

In many ways, software malware and biological viruses are similar, therefore it made sense for us to take a look at what happens in the world with the impact of the Coronavirus, compare it with how cloud environments are being protected, and see what we can learn from the comparison.

Two vulnerabilities found in Microsoft’s Azure cloud services have been recently published by researchers. These vulnerabilities prove once again that un-trusted workloads can come from many places in the cloud environment, including the out-of-your-control cloud infrastructure. Zero-trust environments can be created as a generic solution for such potential attacks.

A few fundamental security problems exist in the traditional microservices identity authentication Methods. These problems result in identity establishment, which is not always trustworthy, and enables potential attackers to pose as legitimate workloads. Adoption of multi-factor authentication for microservices can solve many of these challenges.

Migrating our data to the cloud has never been easier in terms of technology. So why are so many companies still concerned with moving their data to the cloud? The answer lies in the fact that technology is a small part of moving to the cloud. Data cloud migration requires architectural changes and in many times - a mindshift.

While the move to microservices-based architecture is relatively new, it is already mainstream. A majority of companies are choosing it as their default architecture for new development,and you are not cool if you are not using microservices. With regards to migrating legacy apps and breaking them down to microservices, companies are showing more conservatism, and rightly so. The move creates a lot of value, mainly around new features, time to market, and scalability, but it also has its complexities and trade offs.

Confidential Computing technology is an important step toward a safer digital space. Building the right tools and the right architectures around this technology to help companies utilize it is key. These technologies should provide strong confidential computing protection without requiring changing existing software components.
