Overview
Kubernetes Engine for Serverless is an Alto Kubernetes Engine (AKE) service mode that allows you to deploy workloads without purchasing nodes. Kubernetes Engine for Serverless is compatible with native Kubernetes, allowing you to purchase and manage resources natively. It is ready-to-use and supports Cloud products for storage, networking, and more. Kubernetes Engine for Serverless is billed based on the actual amount of resources used by containers, and Cloud ensures secure container isolation.
Benefits
Native Support for Kubernetes
Kubernetes Engine for Serverless is community-driven and supports the latest Kubernetes version as well as native Kubernetes cluster management. It is ready to use in the form of a plugin to support Cloud products for storage, networking, load balancing, and more.
Serverless
Kubernetes Engine for Serverless is a fully managed Kubernetes service, eliminating the need for you to manage any compute nodes. It delivers computing resources using pods. You can purchase, return, and manage cloud resources in native Kubernetes mode.
High Security and Reliability
Kubernetes Engine for Serverless is built on Cloud’s well-developed virtualization technology and network architecture, providing 99.95% service availability. Cloud ensures the virtual and network isolation of Kubernetes Engine for Serverless clusters between users. You can configure network policies for specific products using security groups, network ACLs, etc.
Scaling Within Seconds
Kubernetes Engine for Serverless leverages the lightweight virtualization technology independently developed by Cloud to improve efficiency, allowing you to create or delete a TKE instance within seconds. Kubernetes Engine for Serverless supports automatic scaling of services based on actual loads by configuring the native HPA of Kubernetes.
Cost Reduction
The serverless framework of Kubernetes Engine for Serverless ensures higher resource utilization and lower OPS costs. Flexible and efficient auto-scaling ensures that Kubernetes Engine for Serverless only consumes the amount of resources required by the current load.
Service Integration
Kubernetes Engine for Serverless provides solutions that meet different business needs and can be integrated with most Cloud services, such as CBS, CFS, COS, CloudDB products, VPC, and more.
Features
Multi-Cluster Management
- Kubernetes Engine for Serverless supports cluster management
- Kubernetes Engine for Serverless supports multiple Kubernetes versions
- Clusters are fully managed and you do not need to manage any nodes
- Clusters support native management
- Workloads in a cluster can be deployed across availability zones, and containers can be scheduled across availability zones
Simplified OPS
- Kubernetes Engine for Serverless provides the cloud service model of workload as a service. The lifecycle of cloud resources is the same as that of application workloads. The resources are requested when a workload is created and released when a workload is terminated
- Resources are requested based on workloads
- Container-level auto-scaling ensures high resource utilization
Increased Application Deployment Efficiency
- Kubernetes Engine for Serverless allows you to quickly deploy or update applications using images, YAML files, or templates
- Kubernetes Engine for Serverless supports microservices to reduce code maintenance costs and meet changing business needs
Higher Application Availability and Scalability
- Containers with exceptions can be automatically restored
- Containers can be scaled out horizontally within seconds to cope with unexpected situations during application workload operations
- Application workloads can be scheduled across availability zones to improve the disaster recovery capability
- Kubernetes Engine for Serverless supports rolling updates with no business interruption
Convenient Services
- Kubernetes Engine for Serverless is compatible with the native Kubernetes service mode, which facilitates access between containers within a cluster or access by workloads outside the cluster
- Kubernetes Engine for Serverless supports service discovery using the load balancer domain name or service name plus the port. This eliminates the impact of IP changes caused by the service backend
Convenient Configuration Management
- Kubernetes Engine for Serverless supports different deployment environments for the same application to facilitate update and rollback
- Kubernetes Engine for Serverless supports multiple application versions. However, you can only add versions, not modify them
- Kubernetes Engine for Serverless allows you to import the configuration into containers as a file
