In this article, we looked at new ways to use SQL to easily build applications for engineers with little experience.

If Kubernetes is the pilot that steers the ship, then Helm Charts are the navigational maps that guide the journey correctly. We have seen this happening over the years in the world of software development, one tool comes with an idea, serves the purpose, and becomes obsolete in some years, and then one more tool gets introduced that replaces the old approach, and this journey continues. Similarly, today is the era where Kubernetes is looked upon as the king of container orchestration. Backed by Google, Kubernetes has grown leaps and bounds by increasing its reach and community to every part of the world.

In an ideal world, Docker containers should be ephemeral without any reliance on external storage. In the microservice world, this is achievable when services are connecting to external databases, queues, and other services.

A Brief Overview](https://hackernoon.com/cloud-and-devops-market-in-china-a-brief-overview-wcu30p8)

China is a massive internet and mobile-based internet market. China's cloud needs are growing at high speed. Still, the government’s long-standing protectionist policies, foreign cloud service providers face significant challenges competing with Chinese tech giants such as Alibaba Cloud and others. China acts differently when it comes to cloud and DevOps practices. While the whole world embraces AWS, Microsoft, Google for their cloud-related needs, that is not the case when it comes to China, Alibaba seems a clear winner of the most market share followed by Tencent Cloud, Baidu Cloud, and others. Today we will see a brief about China’s cloud and DevOps market.

Sure, there may be a few Docker Swarm holdouts still around, but for the most part, K8s has cemented itself as the industry standard for container orchestration solutions. As Kubernetes matures, the tools that embody its landscape begin to mature along with it. One of the areas we have seen some optimization, in particular, is in cloud-native storage solutions.

Introduction

Microservices is an architectural style used for creating applications made of individual fine-grained services, which encourages functional decoupling, re-usability, and scalability. This is becoming increasingly popular compared to the monolithic applications we generally build. Monoliths generally lack the flexibility given by microservices in separating out functional components to have their own independent development teams, lifecycles, and deployment.

In this article, we've explored the world of microservices and native applications as well as how Docker can be used to build, run, and deploy them

Intro

Earlier, developers simply wrote their program, built it and ran it. Today, developers need to also think of the various ways of running it whether it be as a binary on a machine (virtual most likely), by packaging it into a container, by making that container a part of a bigger deployment (K8s) or by deploying it into a serverless environment or a service mesh. However, these deployment options are not part of the programming experience for a developer. The developer has to write code in a certain way to work well in a given execution environment, and removing this from the programming problem isn’t good.
