Service fault tolerance

Service throttling

C. Service center

D Service degradation

The Docke image contains the packaged application and the environment it depends on

B. You can package the image through the docker save command

C. You can build container images through the docker build command

D. Container images are a series of hierarchical read-only files managed by storage-driven technology when container images run as containers

A writable layer is added to the top layer of the image

DN returns the execution result to CN after executing the data query task

CN is responsible for decomposing tasks and scheduling task shards to execute in parallel on each DN

DN is responsible for storing the wrist and only supports row storage

CN, as the coordinator node, is responsible for receiving access requests from the application and returning the execution result answer to the client

B. Enterprise host security HSS

ACL firewall

Anti-DDoS Pro and Anti-DDoS Pro

B. Users can use controllers to create pods

In terms of life cycle, Pod should be used for a long time

Pods provide a convenient answer for data sharing, communication and management between their components

Opened VPN Tunnel service, which is used by administrators during operation and maintenance VPN Encrypted communication

VRF isolation: Assign different tenant permissions to different IMS tenants for Layer 2 isolation

VS isolation: Divide different VS logical switches ± core switches for logical isolation for different tenants

C. Firewall isolation: assign different virtual systems (V S YS) for different tenants; Different users access the private network server and use the corresponding VSYS for access control and security identification

VLAN isolation: Assign no VLAN for Layer 2 isolation for different tenants Answer: A

APM demonstrates the call relationship and dependency between applications through topology visualization. The topology uses the Application Performance Index (Apdex) to quantify application performance satisfaction and use different colors to identify the values of Apdex in different intervals for your convenience Quickly identify and locate application performance issues

Through real-time analysis of server-side service flows, APM displays key indicators such as transaction throughput, problem rate, and latency, and uses the health indicator Apdex to score applications to intuitively reflect user satisfaction with applications

APM application performance indicators^ collection, including call chain, SLA, SQL call, JVW and other performance index collection, application The reliability of the performance index acquisition capability will continue to improve with the increase in the number of probes deployed on a single node

Before you activate CTS, you must activate the Object Storage service, and you must have full access to the OBS bucket you want to use

When the user uses anI-AM user (sub-account) to configure dumping in CTS, the operation of the OBS bucket must also be I Am user

After the user activates the cloud audit service, CTS will record some specific key operations, and send notifications to relevant subscribers in real time through the message notification service SMN with these specific key operations, which is triggered by CTS, SMN Complete notification and forwarding
