Benefits of container technology:

Extremely lightweight: only the necessary Bin/Lib is packaged

Second deployment: depending on the image, the container is deployed between milliseconds and seconds

Easy to migrate: build once, deploy anywhere, because it is a self-contained image

Auto scaling: container management platforms such as Docker, Kubernetes and Mesos have inherent flexible management capabilities.

Serverless-Lambda is an event-driven flexible computing platform. The user can write a piece of code and AWS creates a Lambda resource for it, so that when the specified event comes, the runtime of AWS will create the corresponding runtime environment, execute the code, and reclaim the corresponding resources after execution (or timeout).

AWS Lambda is implemented based on container technology. It packages core functions and services into containers, and it also packages user code. At the same time, it highly optimizes the management and scheduling of containers to achieve fast, almost real-time large-scale scale out and scale down. In other words, container technology makes AWS Lambda and IFTTT have completely different effects in the same business scenario. Similarly, it is the easy deployment and orchestration of containers that allows users to focus on the application itself rather than the management of computing resources, which gives rise to the concept of Serverless.

The example of Lacalytics illustrates that container technology is application / service centric (application centric), while traditional virtualization-based cloud platforms are machine-centric (virtual or real physical resources), which is bound to make us think about a lot of so-called DevOps work, which obviously requires continuous improvement but never-ending effort.

Immutable Infrastructure (immutable infrastructure)-the so-called immutable infrastructure means that once the system is deployed, it will not be changed or upgraded. When a service / application needs to be upgraded, just deploy a new version of the system and destroy the old version. In this process, the external service of the system is almost continuous.

Automate the setup and deployment for every part and every layer of your infrastructure.

Never change any part of your system once it is deployed. If you need to change it, deploy a new system.

Immutable Infrastructure vs. Artisanal Infrastructure (handicraft architecture)

Microservice architecture

Several main features of microservices:

Modular services (encapsulation)

Organize around business competency

It's an independent product, not a project.

Simplified communication and connection

Go to the center to manage

Go to the center for data management

Infrastructure automation

Fault tolerant design

Progressive design

From these characteristics, container technology and its related orchestration management framework make it the most natural carrier to implement Microservice architecture. For example, usually a Container image is an independent and complete encapsulation of an application / service, and the general requirement is Stateless, and from a management point of view, Container platforms provide automated lifecycle, scale out and scale down management.
