True

False

The development of a single application becomes a centralized, including all dependencies on bare metal.

Developing a single application while keeping data consistency with transaction control (like row locking then commit, will rollback when failed)

Developing a single application as a suite of small and independent services that are running in their own processes, can develop and deploy independently.

About developing a single application become modular in the level of method/function, but keep only in 1 object app because we need to manage it easily.

Pods can be scaled out to Alibaba Serverless Kubernetes (ASK)

Source Code management, Jenkins, Docker, Ansible, Teraform

Cloud Disk includes SSD, ESSD, and Efficiency: the minimum size is 25 GB

OSS is ideal for archival storage (i.e. lots of writing, less frequent reads)

ACK provides 5 StorageClass types by default, for Cloud Disk

You should create a NAS subdirectory first, and then attach it to ACK

When creating an Alibaba Cloud Container Service for Kubernetes (ACK) cluster, an ingress

dashboard can be installed at creation time.

LogStore can be installed via app catalog.

The Logtail-ds component can be installed by using

Microservice amount * Instance type (e.g. 2C/4G)

Microservice amount * Average instance amount * Instance type (e.g. 2C/4G)

Microservice amount * Average instance amount * Instance type (e.g. 2C/4G) * Redundancy

Microservice amount * Average instance amount * Instance type (e.g. 2C/4G) * Redundancy +

Autoscale nodes instance type

Cluster autoscaler provides "standard mode" and "swift mode" for scale out

Cluster autoscaler will add worker nodes, such as ECS, via AutoScaling when scaling out

Swift mode is quicker than standard mode when scaling out

One cluster only supports one scaling group

Scaling group can be defined or created via a special namespace
