You can follow the tutorials in Quick Start to create an Elastic Computing Service (ECS) instance in the ECS console, and learn how to use the ECS instance by configuring security groups, connecting to the instance, installing third-party services, and resolving domain names. You can also release the instance and view the bills to learn about the fees of the instance during its entire lifecycle.
Background information
An ECS instance comprises the following basic components: instance type, image, block
storage, snapshot, security group, and ENI. These components work together to provide
services.
- Instance type: defines the vCPU and memory specifications of ECS instances and represents the computing capabilities.
- Image: provides all the information such as the operating system and pre-installed software that is required to start ECS instances.
- Block storage: includes system disks and data disks to provide storage capabilities. A variety of disks including cloud disks and local disks can be used. As with hard disks, you can partition, format, create file systems on, and persistently store data on disks that are attached to ECS instances.
- Network: Virtual Private Cloud (VPC) is used. A VPC functions like a data center network that has its own router, switch, and access policies.
- Security group: allows or denies public and internal network requests to protect instances. In most cases, you must add security group rules to a new security group before you add an instance to the group and use the instance to provide services. A security group works similar to a firewall.
