Kubernetes and container-based environments make running microservice-based applications at scale feasible. The ability to add additional capacity, and replace problematic containers quickly, can improve overall system resilience. On the flip side, the benefits of containers also mean they can be challenging when it comes to setting up and managing a networking solution. This article will

The secret to the success of any DevOps initiative is a stable CI/CD pipeline. CI – or Continuous Integration – involves automatically taking newly-merged code and then building, testing, and depositing that code in an artifact repository. CD – Continuous Deployment – involves taking that freshly-deposited artifact and deploying it into a production environment. In

Apache Kafka is a leading open-source distributed streaming platform first developed at LinkedIn. It consists of several APIs such as the Producer, the Consumer, the Connector and the Streams. Together, those systems act as high-throughput, low-latency platforms for handling real-time data. This is why Kafka is preferred by many top-tier tech companies including Uber, Zalando

Kubernetes contains an internal DNS module that automatically discovers and assigns DNS names to individual containers when instructed. In practice, this works very well and there is room for customization. However, when the time comes, we frequently need to expose some or all parts of the Kubernetes cluster to the public. For instance, if a

The journey to business agility must travel the road of agile execution. It may be tempting to look at existing software infrastructure and declare it “good enough” for needed business results – but staying the course (i.e. doing nothing) often only compounds existing business problems. Trying a “do it yourself” approach to implement new open-source
· September 4, 2020 · 7 min readPeople often talk about Kubernetes as if it’s just one tool that is always deployed in a single way. If only! The reality of Kubernetes is that it is much more complicated. Kubernetes is actually more than a half-dozen different tools, which are combined with various third-party services to build out a complete application hosting

In business, stagnation is harmful to the health of a company. Without change, a successful company slowly loses relevance while more daring competitors evolve to provide additional value to their customers. In software development, this is especially true. Development organizations that don’t prioritize innovation soon find that their applications and services are technologically stale and

For the past several years, businesses have been inundated with buzzword-laden rhetoric urging them to embrace “digital transformation,” adopt “agile,” “cloud-native” infrastructures and so on. It’s one thing to talk about the value of these sorts of changes in theory. It’s another to build a digital strategy that puts them into practice – especially given

But leveraging those benefits is not as simple as deploying Kubernetes and then sitting back while your culture is automagically transformed. Instead, organizations seeking to improve their cultures with the help of Kubernetes must take deliberate steps

Much has been written about the technical features and benefits of Kubernetes. Technical advantages, however, are only part of the reason to migrate to Kubernetes. Cultural change is an equally important selling point for Kubernetes. In several key ways, Kubernetes can help to optimize the culture around which IT teams and developers are organized, regardless
