What is cloud native?
Cloud native is a software development and deployment method based on containers, microservices and automated operation and maintenance. It can make applications more efficient, reliable and scalable for a variety of different cloud platforms.
If you want to explain the above concept more directly and popularly.
To be more precise, cloud native is a kind of culture and a trend. It is an inevitable direction of the cloud computing era. The more important significance is to make the cloud the cornerstone of the success of the cloud strategy, rather than an obstacle.
Cloud native is suitable for cloud applications and easy-to-use cloud architecture. From the figure below, you can see that cloud native integrates the previous three layers of cloud (IaaS, PaaS, and SaaS), allowing them to implement applications more flexibly and efficiently.
cloud native architecture
1. Microservices
It is an architectural design that splits a huge app into several independent small independent services, and then strings the services together. Stronger cohesion, more agile
2. Containerization
A lightweight virtualization technology that can provide multiple isolated operating system environments on a single host, and process isolation through a series of namespaces. Each container has a unique writable file system and resource quota. Resource scheduling and microservices are easier
3、DevOps
Not a tool or technique, but a collective term for a set of processes, methods, and systems that facilitate communication, writing, and integration between development, technical operations, and quality assurance departments. Start with the end in mind, integrate operation and maintenance.
4. Continuous Delivery
Narrow down the developer's cognition and flexibly develop the direction.
The value of cloud native
Cloud-native applications have many advantages, which is why more and more people are starting to promote the use of cloud-native.
1. Deploy and scale faster
Since containerized applications can be easily ported across different cloud platforms, they can be deployed to the cloud faster. Also, since each microservice is self-contained, it can be independently scaled as needed without affecting the entire application.
2. Make better use of cloud resources
Containerized applications make better use of cloud platform resources because they can dynamically allocate and release resources when needed. In addition, because the microservice architecture splits the application into small service units, resources can be better utilized, thereby increasing the efficiency of the application.
3. Better maintainability and reliability
Since automated operation and maintenance tools can automate the deployment, monitoring and management of applications, human intervention and errors can be reduced, thereby improving the reliability and maintainability of applications.
Cloud-native applications have advantages such as faster deployment and expansion, better resource utilization, and better maintainability and reliability, which makes more and more people start to promote cloud-native.
How to achieve cloud native
1. Containerized applications
Containerization is one of the core concepts of cloud native. By packaging applications into containers, it becomes easier to deploy and run applications in different environments. Docker is one of the most popular containerization tools out there that helps containerize applications.
In addition, a small program container like FinClip is also recommended here , which can decouple the original complex app and split it into multiple independent small programs to run. In the case of running complementary effects, it can also string services together.
2. Use container orchestration tools
Once applications are containerized, they need to be managed using container orchestration tools. Container orchestration tools, such as Kubernetes and Docker Swarm, can help deploy and manage containers in a cluster.
3. Leverage cloud-native services
Most cloud providers offer some cloud-native services to simplify the development and deployment of cloud-native applications. For example, Elastic Kubernetes Service (EKS), Kubernetes Engine, etc.
4. Practice DevOps
DevOps practices are an essential part of cloud-native development. By practicing DevOps, you can achieve continuous integration and continuous delivery, and improve the quality and reliability of applications through automated testing and deployment.
5. Follow cloud-native best practices
Finally, cloud-native best practices should be followed to ensure that applications perform well in cloud environments. This includes using a microservices architecture to improve scalability and reliability, using container images to ensure application consistency, and reducing application dependencies.
