Edge computing and 5G is a new model of computing that will inevitably become the modus operandi for all organizations that rely on the cloud today. This is especially true of Telcos who will build and operate the new 5G networks of tomorrow. What’s characteristic of edge applications is the low latency and high bandwidth

You need not be too far into your Kubernetes journey to realize that networking in Kubernetes is, in a word, complicated. Not only is the Kubernetes networking architecture complex, but there is a range of configuration options to sort through for the key components that make up that architecture, such as your CNI implementation. To

As applications are being broken down from monoliths into microservices, the number of services making up an application increases exponentially. And as anyone in IT knows, managing a very large number of entities is no trivial task. A K8s Service Mesh, such as Istio, solves challenges caused by container and service sprawl in a microservices architecture

There are many tools in the cloud-native and microservices tool chest. Kubernetes is the go-to for container management, giving organizations superpowers for running container applications at scale. However, running an enterprise-grade, production-level Kubernetes deployment is more than running just Kubernetes by itself. Kubernetes can simplify the management of your containerized applications and services across different

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
· September 16, 2020 · 4 min readIt’s one thing to launch a Kubernetes cluster and deploy a Hello World app on it. It’s quite another to evolve that cluster into a production-ready state, and ensure that it is ready to meet complex needs surrounding storage, networking, monitoring and more. Yet making that transition from testing to production has become the focus

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
