CaaS, also known as container as a service, is a cloud service model that allows users to manage and deploy containers, applications and clusters through container based virtualization. Through CaaS, cloud factories will provide a framework or orchestration platform on which to deploy and manage containers. Through this orchestration, key IT functions are automated.
In general, the CaaS platform is responsible for all network, load balancing, monitoring, logging, authentication, security, automatic scaling, and continuous integration/continuous delivery (CI/CD) functions. This enables enterprises to take full advantage of cloud infrastructure, while helping to avoid the typical platform as a service (PaaS). The basic resource of CaaS is container, which is a common deployment mechanism for cloud native applications and microservices. What are the advantages of CaaS? Today, Micronet will take you to learn more about it. The main points are as follows:
1. Fast deployment and convenient use
Applications developed with containers have everything they need to run and can be deployed in a variety of environments, including private and public clouds. The main advantages of CaaS are fast deployment and easy use, as well as the simplicity of pay as you go cloud model and the above freedom from locking suppliers. By handing over the container infrastructure to the cloud provider, you can start and run without investing in your own hardware or building and running your own Kubernetes cluster (or other container coordination systems).
2. Powerful scalability and flexibility
Contained applications make it easier to migrate applications to different environments or vendor ecosystems, providing greater flexibility and scalability options.
Containers have the function of horizontal expansion, which means that users can multiply the number of the same containers in the same cluster, so as to expand as needed. Therefore, only use and run the required content when needed, which can greatly reduce costs.
3. Faster
In addition, containers are much lighter than virtual machines, which means that they are less resource intensive, which often leads to speed improvement and cost reduction.
4. Higher security
Because isolating a single service in the container can achieve more effective log aggregation and centralized monitoring through the popular zai sidecar deployment model. Containers are isolated from each other, which means that if one container is damaged, other containers will not be affected.
