In simple terms, remote debugging is debugging an application that runs in a place other than your local environment. Let’s look at the problem with the old way of troubleshooting the code for modern software architecture

The Product Requirements Document is essential for any Product Organization. PRDs enable Product Managers to document the problem, requirements, and use cases associated with the question “Why should I build this product or feature?” This blog post will share everything you need to know about PRDs.

It’s important to identify who you are trying to solve the problem for and their current pains with your product and the potential gains from delivering the new feature or product. This post describes the process of defining the “who” through personas.

Clearly, it’s not a bug, it’s a feature. One of my favorite lines in software development, I need to say this once in a while to poke fun at bugs I come across.

Testing can generically follow one of two buckets. The first bucket is testing what you made e.g feature testing. The second bucket is testing what impact you made e.g integration/system testing.

Monitoring and logging are two forms of usage metrics collection. Use monitoring on Kubernetes resources (such as Pods, Services, and nodes) to understand your resource consumption trends and to make decisions for scaling given an application. 

You may have a few applications that need to migrate to Kubernetes. Let’s discuss the three methods of onboarding existing services into Kubernetes. A traditional lift and ship, a monolith application into microservices transformation, and a containerization plan.

Troubleshooting in Kubernetes includes techniques to debug and resolve issues pertaining to containerized applications. Let’s go over how to use port forwarding, container logs, and cluster events to troubleshoot issues within Kubernetes. 

Chaos Engineering is the science behind intentionally injecting failure into systems to gage its resiliency. An informative creed, the Principles of Chaos Engineering, emphasizes the need for a method of comparing a baseline to a hypothesis on what will happen as chaos is injected.

The goal of Creating Containerized Services on Kubernetes is to build, test, and deploy containers. Kubernetes objects support the functions needed to scale and run your applications properly. Let's discuss how to deploy a container image to Kubernetes.

Use the Kubernetes installation options to find a Kubernetes solution that fits your use case. Whether you are just starting, learning, experimenting, or delivering with Kubernetes, there are solutions and content to support your journey. This post describes the Kubernetes installation options.

Lots of organizations are headed down the journey of the container revolution; a revolution where applications and application infrastructure are being containerized.

As our systems become more complex and the operational load from decades gone by with engineer to system burden ratios of one to tens physical machines to one to thousands and beyond today with containerization, help is certainly needed.

Serverless technology represents a seemingly monumental shift in computing. The big allure of serverless is that as software engineers we do not have to worry about infrastructure.

DevOps came from the idea that by working together, Developers and Operations teams could drive the delivery of business value through software. Here are three ways to start adopting DevOps practices and cultures.

Here’s a quick 4-1-1 on what developers need to know to deploy your applications to Kubernetes. This blog post addresses Kubernetes terminology and concepts for developing and deploying your applications to a container environment as a developer.

Application Performance Management (APM) solutions solve the challenges of observability through metrics, logs, and tracing. Learn more about APM solutions here.

One of the first items you learn as a professional engineer is about the presence [and over presence] of logs. On your personal laptop, you might have come across logs in a crash report your operating system vendor collects.

IT audits are intended to make sure our controls are effective. Depending on when we come into a project, the ever in the horizon IT audit would be going through technology and control decisions made before our time on the project.

Now that we have an understanding of what a container can be used for and the important parts that make up the ever-popular container orchestrator, Kubernetes, time for us to spin up a small cluster. Kubernetes as a project moves very quickly and only recently has the cadence slowed on the releases.

The Strangler Pattern made famous by Martin Fowler describes how software evolves in our enterprise -- though this observation can also be made with reference to the platforms and pipelines that support our applications. 

Eclipse Vert.x implements a multi-reactor pattern supported by eventloops. In a reactor pattern, there exists a stream of events delegated to handlers by a thread called an eventloop.

CI is the process of taking a developer’s code throughout the various steps necessary for it to be ready to be deployed as an application. This deployable application is called an artifact. 

Continuous Deployment results in many production deployments every day since every change in the pipeline automatically gets delivered to a user. A prerequisite to Continuous Deployment is Continuous Delivery.
