GitOps is an operational framework for declarative-driven systems such as Kubernetes. More specifically, it provides a set of best practices that converge the runtime state of the services with the declarative state defined in Git. On the other hand, Argo CD is a declarative, continuous delivery tool for Kubernetes. Argo…

Developer onboarding and experience gets simplified every day. But while developers use many modern software development techniques-including 12-factor, cloud-native, and continuous integration-developer onboarding remains a challenge. Therefore, what developers need is an integrated, self-contained platform that helps them get started with ease. Gitpod is one such way we can steer…

Java is the quintessential language runtime for enterprise applications built on monoliths, microservices, and modular architecture patterns. But when it comes to “Enterprise Java,” Spring is the de facto framework of choice. The Spring ecosystem-with the simplicity of Spring Boot has grown to provide integration touchpoints to a majority of…

The evolution of “build once, run anywhere” containers and Kubernetes -a cloud-agnostic, declarative-driven orchestration API-have made a scalable, self-service platform layer a reality. Even though it is not a one size fits all solution, a majority of business and technical challenges are being addressed. Kubernetes as the common denominator gives…

K8s backup & restore using Velero — Velero is an open-source backup tool to save and restore the Kubernetes cluster state. The K8s cluster state, including the mounted data, is persisted in an external object store used to restore it either in the same cluster if lost/deleted by accident or in a new cluster elsewhere in a…

Git-based Dev workflow in the Cloud — Developer experience and onboarding is a space that is getting simplified every day in different forms and shapes. Though we practice vcs driven development, 12-factor, cloud-native, etc. dev onboarding is still a challenging affair. We still have to install tools, sometimes might have to run some services locally, etc as…

Spring Boot Native via Cloud Native Buildpacks — The GraalVM native image is gaining a lot of popularity for serverless style scale to zero, on-demand scale-out/in architectures where the container boot time and runtime memory footprint play a massive part in both technical and commercial sense. Traditionally java apps are just in time compiled by the runtime, and…

Buildpacks Re-Imagined — In this blog, let’s look at Cloud Native Buildpacks(CNB) specs and the recently announced open-source implementation of the CNB — paketo-buildpacks. Need for a Spec The art of creating a self-contained runnable artifact from the source code isn’t new. It started with Heroku and then the Cloud Foundry community adopted it and took it…

JHipster ♥ Spring Boot ♥ K8s — JHipster is a developer-friendly platform to bootstrap, iterate, build and deploy cloud-native Spring Boot-based services. It also generates scaffolding code for front-end services based on widely used frameworks/libraries like Angular, React, etc. It does provide integration touchpoints with various data, logging, and monitoring services as well. Over the years scaffolding…
