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.

In the ever-evolving landscape of modern software development, where speed, quality, and collaboration are paramount, the concept of preview environments has gained significant traction. These virtual sandboxes serve as vital tools that empower developers to thoroughly test their code changes in isolated environments before integrating them into the main codebase. The advantages are multifaceted, ranging from reduced bugs to enhanced collaboration and accelerated software delivery.

In the realm of software development and testing, end-to-end (E2E) testing plays a pivotal role in ensuring the robustness and reliability of web applications. Unlike unit or integration testing, which focuses on specific components or integrations between them, end-to-end testing evaluates the entire system as a whole. This includes testing the flow from the user's perspective, from start to finish, and often involves multiple systems and components working in unison.

In today’s world, with Large tech giants and businesses looking forward to moving toward serverless architecture, there has been a significant demand for scaling the applications. It’s therefore no surprise that millions of companies worldwide have adopted, or are planning on migrating to a Kubernetes and AWS Lambda solution to take their serverless applications to the next level.
