Using SFS as the base, each employee mounts SFS to the local area

Use EVS as the base to build your own network disk service

The service builds a unified synoptic platform, and the backend uses the unified interface to connect and use SFS/OBS storage

Using OBS as the base, each employee mounts the object storage to the local server through obsfs

the ports opened by the offline service system, according to the guidance on the cloud set the appropriate ports required by the service module when the security module is opened

After the service is migrated to the cloud O&M personnel open each host for maintenance 22 and 3389 port, so that it works Operate O&M anywhere, without geographical restrictions, higher work efficiency, use diverse cloud services, and flexible resources Features, choose the right specifications, put web. The end and application are deployed using the same virtual host, middleware and database Deploy with cloud services provided by a cloud

From the perspective of architecture and maintenance convenience, directly copy the offline model to purchase 5 bare metal servers on the cloud to deploy services

CCE cloud container engine supports the creation of CA policies, scales capacity according to CPU/memory allocation ratio, and periodically scales nodes according to time

HPA expands according to the monitoring standard. and when the cluster resources are insufficient, the newly created pod will be in the Running state, CA All Running states are checked for POD According to the user-configured scaling policy, select the most suitable node pool to scale

Under normal circumstances, the two need to be used together, because HPA requires sufficient resources in the cluster to successfully expand. and when the cluster resources are not enough, the CA needs to expand the nodes so that the cluster has sufficient resources

When the cluster has a large amount of spare resources after HPA scale-in, the CA scale-in node needs to release resources so as not to cause waste

Configure VPN interconnection

Jiuji cloud connection to achieve interconnection

Configure a peering connection for the two VPCs (the VPC subnets do not conflict), and access each other through the peering connection

Configure EIP for the cloud hosts that need mutual access, and

Use the cycle scaling strategy of Auto Scaling service to expand capacity in advance before service peaks, scale down after business peaks, and cope with cycle and service pressure

Use the alarm policy of AutoScaling to expand capacity when high service CPU usage is detected to cope with sudden service peaks

The network front-end uses ELB load-balancing products to ensure that the automatically scaled ECS can distribute service pressure

Before the peak of periodic services, manually expand the vertical capacity by changing the ECS specifications to achieve the of upgrade without shutdown

Use paginated query to avoid throughput of full data at one time, and can use 15 data network traffic

B-Tree index reduces the operation of the hard disk by 10 according to the query conditions to improve the query efficiency

Reduce large-scale transaction operations in the business, avoid processing too much data in one transaction, remove unnecessary queries, try to ensure that all read operations are necessary in transactions, and reduce the amount of locked data

Appropriately increase the cache capacity, increase the cache hit ratio, and reduce the load of the hard disk 10
