Source is allocated.
Example two：
As shown in figure 5, this example may be based on the dynamic adaptation side of the PAAS resources of the mixing shown in Fig. 4
Method, specifically includes：
Accounts at different levels apply for PAAS resources in the case where user indicates；The application of PAAS resources is sent to PAAS
Resource control device.PAAS resource control devices, after receiving application, carry out the PAAS in public cloud domain first
Resource allocation.It was found that the PAAS resources in public cloud domain cannot meet the resource requirement of application, to private clound domain
Application PAAS resources.If private clound domain can provide unappropriated PAAS resources, by former private clound
The PAAS resource allocations in domain are in public cloud domain.Allotment is finally based on, by the PAAS resources in private clound domain
In moving to public cloud domain.
Example three：
The specific allotment flow to can be applied to cloud resource of the invention shown in Fig. 6, including：
Step S1：Resource control device receives the n task of resource bid；The n is not less than 1
Integer；
Step S2：Calculate the priority parameters of each task.
Step S3：N task parameters are ranked up to n task according to priority parameters；
Step S4：Based on the process task one by one that sorts；Priority parameters priority treatment high.
Step S5：Return to result.
Based on step S1 to step S5, it is introduced in detailed below.
When user in public cloud domain initiates new application or PAAS resource bids, born by resource control device
Duty resource allocation.Resource control device is using a kind of weighting sequential based on SLA (service-level agreement) point
With strategy.The allocation strategy is described as follows：
1. it is raising allotment efficiency, lifting system utilization of resources quality, resource control device Timing Processing resource
The request of application, i.e., carry out a PAAS resource allocation every T time, between intervals interior receiving
PAAS resource bids are asked, and are not processed.According to production experience, T can be set to 24h.The T
It can be the first specified time in previous embodiment.
2. user's mixing cloud system when PAAS resource bids are initiated is set according to factors such as account levels first
SLA (SLA is the natural number more than or equal to 1), SLA is bigger, represents its grade of service higher；
3. when each user initiates PAAS resource bids, resource control device is equivalent to receiving a task
Task, SLA, application time time of the task comprising this PAAS resource bid, application weights weight.
For example：Application to database resource can be according to it to memory space, internal memory, RPO, RTO, backup etc.
Factor calculates its weights；Application to middleware resource can be calculated according to it to factors such as number of concurrent, thread pools
Its weights.Weight is bigger, and the PAAS resource bid requirements for representing the user are high；
4. assume that resource control device receives 1.....n task in predetermined distance time T, is named as
Task1, task2.....taskn, for each task, will be according to its service-level agreement SLA, application time
The factors such as time, resource bid weight w eight calculate its priority priority.Its computational methods is as follows：
For the n application time time1 of task, time2....timen is ranked up from back to front,
By time1, time2....timen corresponds respectively to a natural number N (1=<N<=n) as its sequential
Value, application time more early task, the corresponding N values of its time are bigger；
Priorityn=XSLAn*timen*weightn
X is the natural number more than or equal to 1, is the regulatory factor that priority parameters calculate Priority, same
When criticizing task priority calculating, X palpus values are consistent.The general values of X can be for 2) in current system.
5. according to the result of calculation of Priority, to task1, task2.....taskn according to Priority from big to small
Order carry out rearrangement TASK1, TASK2 ... TASKm (1=<m<=n)；
6. to TASK1, TASK2 ... TASKm carry out sequential processes to resource control device, its processing method
It is as follows：
Can be to carry out one of handling process of task one by one in the step S4 shown in Fig. 7.
PAAS resources are applied for from public cloud domain based on TASK.TASK represent according to priority parameters
Task after sorting from high to low.For example for the resource bid of TASK1, resource control device is looked into first
Whether ask in its public cloud domain has enough resources to be available for distribution, if public cloud domain resource meets demand directly from
PAAS resources are distributed in public cloud；Transfer treatment if public cloud domain resource is unsatisfactory for the demand of TASK1
TASK2, by that analogy until task is disposed or all tasks finish public cloud domain resource poll；
Judge whether to apply successfully, if applying successfully directly returning to result, if not applying successfully, sentencing
Whether all tasks of breaking applied for PAAS resources to public cloud domain；It is to enter subsequent operation that judged result is,
If judged result is no, next task is obtained according to priority parameters.
Apply for PAAS to private clound domain from for the remaining task order of PAAS resources applied removes task
Resource, and record application result.
Judge all tasks whether to private clound with applied for PAAS resources, if judged result is no, return
Previous action institute is gone back to, result is if the determination result is YES returned.
In above-mentioned processing procedure, task has been disposed, resource control device then directly return all into
Work(treatment mark；If task is also untreated complete, illustrate that public cloud domain resource can not meet the resource of all tasks
Demand.Resource control device is descending one by one to private according to the sequence of priority parameters for remaining task
There is cloud domain to propose PAAS resource bids.After private clound domain is connected to the resource bid request of resource control device,
Available minimum PAAS units are calculated by its resource analysis module first, then by resource control device
By in unit addition public cloud domain PAAS domains.After private clound domain receives total domain PAAS applies,
Resource analysis module calculates PAAS units (such as database, the centre of minimum according to private clound domain resource situation
The virtual machine or physical machine of part platform), resource control device is divided into public affairs by changing the IP of the resource
There is the VLAN in cloud domain, or modification ACL controlling networks are accessed, and realize public cloud domain network up to the PAAS
Resource.PAAS resource adaptations module in the resource control device can be by the new resource dynamic adaptation for adding
To in the PAAS resources of public cloud domain, database, middleware, caching, the integration environment of various patterns are supported
Deng service.
Example four：
(1), when PAAS public clouds domain receives the database (Date Base, DB) transferred in private clound domain
After resource, intelligent management and control module will determine that the DB types at demand end, be started according to different type corresponding suitable
With algorithm, the DB to there is dilatation demand implements dynamic capacity-expanding.
(2), as shown in figure 8, be deployed with the host P1 in public cloud domain three sets of data storehouses (DB1, DB2,
DB3), DB3 requires dilatation CPU, data buffer storage, backup space and changes parameter, but P1 hosts
Without additional hardware resources, modification parameter will influence DB1 and DB2, now using the resource to private clound domain
Draw the dilatation for implementing DB3 by host P2 hosts.
(3) when, implementing dilatation and parameter modification to the DB3 under P1 using P2, intelligent adaptation algorithm is by root
The disturbance degree Y1 of resettlement DB3 is calculated according to the operation factor in three sets of data storehouses, and moves DB1, DB2
Disturbance degree Y2.
When computationally stating disturbance degree, it will use the parameter in table 1 to table 2.
| Data capacity | Operation factor F1 |
| 0-100G | 1 |
| 100G-500G | 2 |
| 500G-1T | 3 |
| 1T-5T | 4 |
| More than 5t | 5 |
Table 1
| Concurrent connection number | Operation factor F2 |
| 0-10 | 1 |
| 10-100 | 2 |
| 100-300 | 3 |
| More than 300 | 4 |
Table 2
| Business continuance | Operation factor F3 |
| Backup and Restore | 1 |
| It is emergent | 2 |
| Dual-active | 3 |
Table 3
| Assurance level | Operation factor F4 |
| 5*8 | 1 |
| 7*24 | 2 |
DB migrates disturbance degree Y1=F1+F2+F3+F4 ..., moves the disturbance degree Y2=of DB1, DB2
F1 '+F2 '+F3 '+F4 ' ..., work as Y1<=Y2, illustrates that resettlement DB3 influences are small, using DB3 is moved, instead
As the same
(4), before DB3 is moved, needed for P2 host's DB main frame machines have reserved DB3 dilatations
Data buffer storage, cpu resource, and parameter modification is completed, 1 grade and 0 DBMS are passed through by resource control device
Backup and Restore, real time data synchronization etc. realize the Data Migration of DB3, and application program is reconnected can be completed
The dilatation of DB3
(5) Y1, is worked as>Y2, implements DB1, DB2 and moves to host P2, the same step (4) of migration scheme,
Remaining resource will supply DB3 after migration, and implement parameter modification, and application program is reconnected can be completed
The dilatation of DB3.
The dilatation of the DB3 specifically can as shown in figure 9, including：
Judge that P2 is by there are available resources, if into next step, the resource in private clound domain is applied for if not；Here
Resource can be database resource etc. in PAAS resources.
Calculate disturbance degree Y1 and disturbance degree Y2.
Judge Y1 whether less than or equal to Y2.
Y1 is less than or equal to Y2, and that implements DB3 moves to P2.
Y1 is more than Y2, implements DB1 and moves to P2.
