Most development projects involve a wide range of environments. There is production, development, QA, staging, and then every developer's local environments. Keeping these environments in sync so your project runs the same (or runs at all) in each environment can be quite a challenge. There are many reasons for incompatibility, but using Docker will help you remove most of them.

From its humble beginnings, Kubernetes’ growth story continues to be a testament to the power of open-source collaboration, and its current 1.28 second release is certainly no exception. It’s not just a product of ingenious coding but also the sweat and night oil of a global community – from seasoned industry stalwarts to students just making their debut in the open-source world.

Docker is designed for Linux. It works most efficiently on Linux systems due to its close integration with the Linux kernel. When handling large filesystems, like the ones built with PHP and Node, Docker desktop (MacOS Environment) experiences significant lag. The main reason is how file synchronization is implemented in Docker for Mac. Plus, disk space consuming behavior of such big PHP Projects.

We are excited to announce the publication of our 2023 State of Calico Open Source, Usage & Adoption report! The report compiles survey results from more than 1,200 Calico Open Source users from around the world, who are actively using Calico in their container and Kubernetes environments. It sheds light on how they are using Calico across various environments, while also highlighting different aspects of Calico’s adoption in terms of platforms, data planes, and policies.

I’ve worked on on-premised and managed Kubernetes clusters for more than seven years. What I can say is that containers have drastically changed the hosting landscape! It has brought a lot of facilities where complex setups were required. Having several instances, with rolling restart, zero downtime, health check, etc. It was such a pain and time effort before (implementing VRRP solution, application monitoring restart with monit like, load balancing haproxy like)!

Microservices architecture is a software development approach where an application is built as a collection of small, loosely coupled, independently deployable services. Each service focuses on a specific business capability and operates as an autonomous unit, communicating with other services through well-defined APIs. This architectural style is often used in the context of DevOps to create more efficient, scalable, and manageable systems.
