Description

Service configuration design apparatus and service configuration design method

The present invention relates to a service configuration design apparatus and a service configuration design method for designing the configuration of a system that provides an ICT service.

A system that provides an ICT (Information and Communication Technology) service (for example, Web site, video distribution, business system) provided via a communication network such as the Internet is composed of a plurality of components. For example, a Web system is configured by a plurality of components such as a Web server, an application server, and a database server (see, for example, Patent Document 1).

Patent Document 1 describes a system configuration plan generation device that generates a system configuration plan that provides an ICT service in consideration of component requirements desired by a user.

Patent Document 2 introduces a service chain composed of a plurality of functions for realizing one service.

Japanese Patent Laying-Open No. 2015-219795 International Publication No. 2015/194182

An example is a system that provides an ICT service provided to a terminal such as a mobile phone or a personal computer via a communication network. FIG. 14 is a system configuration diagram showing a general service providing system 500 that provides an ICT service via the Internet 600.

As shown in FIG. 14, the service providing system 500 includes servers such as Web servers 510a and 510b, an application server 520, and a database (DB) server 530. In addition, the service providing system 500 includes a firewall (FW) 540 that eliminates unnecessary traffic, and a load balancer (LB) 550 that converts an IP (Internet Protocol) address. Further, the service providing system 500 may incorporate a function of a proxy (Proxy) that stores a cache or a function of NAT (Network Address Translation) that performs address conversion. Hereinafter, modules that provide various server functions and network functions are collectively referred to as nodes.

In order to improve the processing at the node, resources such as CPU (Central Processing Unit), memory, and network I / O (Input / Output) may be added. In addition, an accelerator that supports AES-NI (Advanced Encryption Standard Standard New Instructions) may be used, or parallel processing by scale-out may be executed.

For example, in a certain FW node, if there are 10 types of resource allocation patterns, 3 types of accelerators (including non-use of accelerators), and the maximum number of scales is 20, the instance configuration (pattern) candidate for that node is There are 10 × 3 × 20 = 600 patterns. Further, when a providing system composed of various types of nodes is configured by connecting NAT nodes, proxy nodes, etc., there are 600 ⁵ = 777,600,000,000,000 instance configuration candidates. To verify which pattern is optimal, a test for each pattern is required. Therefore, the verification time becomes enormous.

Also, even if the type is the same, the resources consumed by the internal processing are different between nodes that execute different processing, so the optimal resource allocation pattern is also different. For example, in the case of FW, a CPU resource with high performance is required when performing a virus check on mail. When performing filtering of moving image distribution, network I / O resources with high performance are required. When both processes are performed simultaneously, the optimal resource allocation pattern is different, for example, more resources are required than the sum of the CPU resources and network I / O resources required by each single function.

Therefore, it is necessary to verify an enormous number of instance configuration candidates and resource allocation patterns before the optimal instance configuration and optimal resource allocation pattern can be derived. That is, there is a problem that it takes a long time to design an optimal system that provides an ICT service.

In this specification, the function of each node constituting the service chain corresponds to a service. Therefore, the “service configuration” is a concept representing how a plurality of nodes are combined. Further, the “service configuration” includes the concept of resource allocation in each node. “Service configuration design” is to determine a combination of a plurality of nodes in order to satisfy a required service level and to determine the amount of resources allocated to each node.

An object of the present invention is to reduce the time required for designing the configuration of a system that provides a service.

The service configuration design apparatus according to the present invention formulates a relationship between a business pattern defining means for analyzing a traffic of each node for providing an ICT service and defining a business, and a business and a resource consumption amount in each node. Service configuration derivation means for generating a business / resource relational expression and service configuration derivation means for generating a service configuration based on a design derivation tree representing a combination of resources that can be included in a node. The means generates a service configuration after narrowing down resources in the design derivation tree based on the business / resource relational expression.

The service configuration design method according to the present invention analyzes the traffic of each node for providing an ICT service, defines a business, formulates the relationship between the business and the resource consumption in each node, and creates a business / resource relationship. An expression is generated, and after narrowing down resources in a design derivation tree that represents a combination of resources that can be included in a node based on a business / resource relational expression, a service configuration is generated based on the design derivation tree.

The recording medium according to the present invention is a computer-readable recording medium storing a service configuration design program, and the service configuration design program, when executed by a processor, traffic of each node for providing an ICT service. Included in the node based on the business / resource relational expression, the process that defines the business by analyzing the process, the process that formulates the relation between the business and the resource consumption at each node, and the business / resource relational expression After narrowing down resources in a design derivation tree that represents a possible resource combination, processing for generating a service configuration based on the design derivation tree is executed.

According to the present invention, the time required for the configuration design of a system that provides a service is shortened.

The service requirements include at least information indicating connection of nodes as service configuration requirements, information indicating a service level (for example, data transfer rate), and information indicating a node type (node type).

FIG. 4 is an explanatory diagram showing an example of service requirements stored in the service requirement storage unit 110. In the example illustrated in FIG. 4, as illustrated in FIG. 4A, the service requirement storage unit 110 stores service configuration requirements, service level requirements, and business pattern IDs (pattern IDs) as service requirements. Further, as shown in (B), the service requirement storage unit 110 also stores information indicating the node type included in the service configuration requirements. In the example shown in FIG. 4, the service specified by the service ID “service1” includes a plurality of ICT services (the moving image distribution service specified by patternA and the predetermined application service specified by patternB).

For example, using Juniper (registered trademark) FW, LVS (Linux (registered trademark) Virtual Server) load balancer, Apache (registered trademark) Web server, Tomcat server, MySQL (registered trademark) DB, When a service capable of processing 100 Mbps is required, the service requirements are specified as shown in the first line in FIG.

FIG. 5 is a flowchart showing the processing executed by the business pattern definition unit 103.

The business pattern definition unit 103 reads the traffic information corresponding to the node in the new service from the measurement information storage device 204 (step S11). Then, the business pattern definition unit 103 executes the process of step S13 for each node type stored in the service requirement storage unit 110 (steps S12 and S14).

In step S13, the business pattern definition unit 103 defines a business pattern based on protocol information and content information in traffic information.

For example, when traffic information as shown in the traffic information table illustrated in FIG. 2 is used, the business pattern definition unit 103 uses “HTTP” as protocol information and “Content-Type: video / flv” as content information. And define a business pattern of “video traffic”.

The business pattern definition unit 103 stores business pattern information related to the defined business pattern in the business pattern storage unit 113 (step S15).

In the example illustrated in FIG. 6, name data representing a business pattern and data representing an identification pattern (protocol information, content information, etc.) are registered corresponding to the pattern ID.

Next, the process of generating business / resource relational expressions will be described.

FIG. 7 is a flowchart showing processing executed by the business / resource relational expression generation unit 102.

The business / resource relational expression generation unit 102 reads the log and the resource consumption rate included in the traffic information from the measurement information storage device 204 (step S21). The traffic volume can be known from the log. Further, the business / resource relational expression generating unit 102 reads business pattern information from the business pattern storage unit 113 (step S22).

Then, the business / resource relational expression generation unit 102 classifies the traffic information for each business pattern (step S23). Further, the business / resource relational expression generating unit 102 executes the process of step S25 for each node type (steps S24 and S26).

In step S25, the business / resource relational expression generation unit 102 generates a business / resource relational expression by performing mathematical analysis such as regression analysis using the traffic amount of the business pattern as an objective variable and the consumption rate for each resource as an explanatory variable. To do. At this time, the business / resource relational expression generation unit 102 sets a threshold value of the precision of the relational expression, and deletes an explanatory variable having a low correlation with the objective variable. That is, the business / resource relational expression generation unit 102 generates a business / resource relational expression narrowed down to a resource type effective for the performance of the node type.

The business / resource relational expression generation unit 102 stores the generated business / resource relational expression in the business / resource relational expression storage unit 112 (step S27).

FIG. 8 is an explanatory diagram showing an example of a business / resource relational expression stored in the business / resource relational expression storage unit 112. In the example shown in FIG. 8, the resources are CPU, RAM, NWIO, and IOPS.

The business / resource relational expression generating unit 102 calculates the significance probability (p value) of the coefficient of the explanatory variable and stores it in the business / resource relational expression storage unit 112 together with “significant F” indicating the significance of the relation. .

As an example, when the business / resource relational expression generation unit 102 sets “significant F ≦ 0.05” as a threshold of accuracy of the relational expression, the correlation with the objective variable is low so as to satisfy this threshold Sharpen variables.

For example, in the relational expression “node ID = fw1” and “business pattern = patternA (video traffic)”, the explanatory variables of the RAM are deleted, and the explanatory variables are effective for the performance of the node type fw1. O and disk IOPS.

Next, the service configuration optimization process will be described. In the present embodiment, a design guide tree and a business / resource relational expression are used in the service configuration optimization process.

FIG. 9 is an explanatory diagram illustrating an example of a design derivation tree (hereinafter, also referred to as a derivation tree) stored in the design derivation tree storage unit 111.

The design derivation tree storage unit 111 stores derivation trees in which all combinations of resources are set in a tree shape for each of a plurality of types of nodes for providing one or a plurality of ICT services. Yes. A derivation tree indicated as ID: derivation tree 1 in FIG. 9 is stored in the design derivation tree storage unit 111 in advance. The derivation tree shown as ID: derivation tree 2 is an example of a derivation tree in a state after the pruning process is performed by the service configuration derivation unit 101.

FIG. 10 exemplifies resource amounts of resources in each combination (resource type) of resources that can be included in each node. The resource amount illustrated in FIG. 10 is stored in the design derivation tree storage unit 111. For example, CPU [Large] indicates that the amount of CPU resources in the combination of resources (CPU, RAM, NWIO, and IOPS) is large.

FIG. 11 is a flowchart showing processing executed by the service configuration deriving unit 101. Here, the requirement of the service specified by service1 shown in the first line in FIG.

The service configuration deriving unit 101 reads out service requirements from the service requirement storage unit 110. That is, the service requirement shown in the first line in FIG. 4A stored in the service requirement storage unit 110 is read.

Next, the service configuration deriving unit 101 sets a business pattern and traffic volume as an ICT service (step S31). In this example, “video traffic” (pattern A) and “application service” (pattern B) are set as business patterns. Then, the service configuration deriving unit 101 reads data representing the derived tree from the design derived tree storage unit 111, and reads the node type business / resource relational expression included in the service from the business / resource relational expression storage unit 112 (step S32). ).

The service configuration deriving unit 101 summarizes business / resource relational expressions, business patterns, and traffic volume information for each node type. Then, the service configuration deriving unit 101 executes the processes of steps S34 to S37 for each node type (steps S33 and S38).

In step S34, the service configuration deriving unit 101 determines whether or not the number of business patterns is 1 (step S34). When the number of business patterns is 1, the service configuration deriving unit 101 determines the amount of resources based on the magnitude of significance (significance probability (p value)) of the explanatory variables in the business / resource relational expression of the business pattern. Is changed (step S36). That is, the service configuration deriving unit 101 performs pruning processing of the derived tree. Note that the service configuration deriving unit 101 allocates a minimum amount to a resource that does not have a corresponding variable. Further, the resource amount is defined as illustrated in FIG.

For example, the service configuration deriving unit 101 changes the allocation amount of the resource amount based on the significance probability (p value) of the explanatory variable of the business / resource relational expression of the business pattern. Specifically, as an example, a derived tree according to a determination rule such as “the resource amount Large if p value ≦ 0.01”, Medium if 0.01 <p value ≦ 0.05, and Small if 0.05 ≦ p value ”. Pruning. As a result, a derivation tree indicated as ID: derivation tree 2 is generated from the derivation tree indicated as ID: derivation tree 1 in FIG.

In the example illustrated in FIG. 9, in the ID: derivation tree 1, the node “fw1” が あ る has three branches of CPU [Small], CPU [Medium], and CPU [Large]. It is narrowed down to CPU [Large].

When the number of business patterns is 2 or more, the service configuration deriving unit 101 uses a plurality of business / resource relational expressions, but generates a pruning pattern from the plurality of business / resource relational expressions. As an example of the pruning pattern, an average value of significance probabilities (p values) of explanatory variables of a plurality of business / resource relational expressions is used.

For example, the significance (p value) of explanatory variables for video distribution (video traffic: patternA) is (cpu, RAM, NWIO, IOPS) = (0.001,-, 0.04,0.03) and application service (application traffic: patternB) When the significance probability (p value) of the explanatory variable is (cpu, RAM, NWIO, IOPS) = (0.042,0.008, −, 0.04) (see FIG. 8), the service configuration deriving unit 101 calculates the average value. , (Cpu, RAM, NWIO, IOPS) = (0.021,0.008,0.04,0.03) is used. In this case, the service configuration deriving unit 101 collectively generates a service configuration for a plurality of tasks (ICT service).

Then, the service configuration deriving unit 101 executes the process of step S36.

The service configuration deriving unit 101 generates instance candidates for the service configuration by combining the candidate components for each node (step S39).

As described above, in the present embodiment, when selecting system component candidates for providing a service based on log information collected during operation of an ICT service or the like, the system is configured by pruning a derived tree. Since the candidate elements are narrowed down, the candidate elements are derived in a short time.

Note that the service configuration deriving unit 101 selects a best service configuration by performing a test on the candidate components. Then, the service configuration deriving unit 101 stores the selected service configuration in the service configuration storage device 203.

FIG. 12 is an explanatory diagram showing an example of a service configuration stored in the service configuration storage device 203. As shown in FIG. 12, the service configuration storage device 203 stores data that can specify how to link each service (each node) for realizing the ICT service and the amount of resources in each service.

Note that the example illustrated in FIG. 12 is an example that satisfies the service requirements illustrated in FIG.

Also, the configuration change device 202 reads the service configuration newly stored in the service configuration storage device 203 and constructs a service chain on the service execution device 200 based on the service configuration.

In the present embodiment, for example, a service configuration suitable for a new ICT service is designed, or the service configuration (service chain configuration) is automatically improved based on log information measured during the operation of the ICT service. It is used for applications that improve service quality.
