Description

TECHNICAL FIELD:

The exemplary embodiments of this invention relate generally to data processing systems, methods and computer software, and relate more specifically to determining a user-optimized application solution on a cloud platform.

BACKGROUND:

A cloud platform can be considered to be a collection of data processing hardware and software that is configured to address the needs of a user. The data processing hardware and software can be considered from the user's perspective as a virtual assemblage of data processing hardware and software that is hosted by a provider of the cloud platform, i.e., the actual physical hardware and software components such as computers, servers, storage devices, operating systems, middleware, databases, network interfaces and the like are not hosted by the user but instead by the cloud platform provider.

In a market place associated with a cloud platform provider a user searches for a solution (e.g., bundling certain catalog items or composing services) to serve the user's needs. A number of issues can arise from the user's perspective when searching for an optimum cloud platform solution. These issues can include one or more of the following (as examples).

(a) How does the user ensure that a given solution is technically sound?

(b) How does the user find a highest performing solution within the budgetary constraints of the user?

(c) How does the user find a lowest priced solution that will still fulfill the needs of the user?

The exemplary embodiments of this invention address and solve these and other issues that can arise when configuring a solution on a cloud platform.

SUMMARY:

An aspect of the exemplary embodiments of this invention provides a system that includes at least one computer connected with at least one memory that stores computer program code executable by the at least one computer. The system further includes a user interface connected with the at least one computer. In the system execution of the computer program code results in performance of operations that comprise, in response to input from a user received via said user interface, accessing a database to select at least one predetermined template comprised of a hardware and software instance of a data processing system that is implementable as an application solution on a cloud platform; comparing the at least one selected template against a set of constraints; establishing an instance of a cloud based solution for the user based on the selected template if the set of constraints is compatible with requirements of the selected template; and validating the established cloud based solution against user-uploaded software and workloads to ensure that the cloud based solution satisfies requirements of the user.

DETAILED DESCRIPTION:

The various embodiments of this invention provide tools, methodologies, systems and software to enable the user to arrive at an optimum cloud application solution that meets the operational constraints of the user's workload characteristics, such as throughput, availability and storage capacity, within budgetary constraints imposed on the user. The various embodiments merge technical and business aspects and suggest to the user a solution based on the user's workload characteristics and budget.

The use of the embodiments of this invention creates a number of technical solutions along with required supporting components. The embodiments create the technical solutions based at least on user input and technical feasibility, and operate to ensure that a composition of the resources in the solution is technically sound.

The embodiments of this invention can vary the metal (hardware, such as CPU, memory and storage) and supporting image (e.g., software such as middleware that operates beneath a user's application software) to support the suggested solutions. For each technical solution the embodiments compute a correct combination of metal and the supporting image to host the solution. The computation can consider a license model which could limit the number possible combinations and also affect a pricing computation. For example, a particular database could have enhanced performance when executed on a server with four CPUs rather than on a server with two CPUs, but it may require a more expensive license from the database vendor in order to be deployed on the higher performance capacity server.

The embodiments of this invention also create associations between each solution and different combinations of metal and supporting image.

An aspect of the embodiments of this invention is a computation of the cost of these different associations. This can be a multi-step process that involves computing the cost of a particular technical solution and computing the correct charge for the different associations.

Computing the cost of a technical solution can involve, for example, a generally per resource cost of management (possibly by type), a consideration of a base computer resource consumption (computer, required physical storage, etc.), as well as any software licensing fees by license metric. These license metrics can include, for example, a number of CPUs, expected numbers of system users (e.g., customers or clients of the user), the number of connections, etc.) In the case of using a public cloud some of these computations can be simplified by basic pricing information being available that masks from the user some or all of the detailed breakout.

Note that while a public cloud is mainly considered herein the embodiments of this invention can be applied equally to a ‘private’ cloud environment, such as a cloud maintained by an organization such as an agency or a corporate enterprise for use by its employees and contractors. In such a case, and by example, a particular user can still be bound by departmental budgetary and other constraints when configuring a cloud platform solution to perform a certain task.

The embodiments of this invention compute the cost of the different combinations of the metal and the supporting image, compute the total cost of the different associations between the technical solutions and the combinations, and compute a correct amount to be charged to the user for the different associations.

An aspect of the embodiments of this invention is an ability to iterate a set of the different associations between the technical solution and the combinations if there is a shortfall between the various solution prices and the budget of the user. The iteration can involve varying the resources of the solutions to possibly arrive at better technical solutions, and then computing the prices of the better technical solutions with different combinations of metal and supporting images to ensure that the computed prices are still within the user's budget.

With regard to recommending optimal solutions, another aspect of the embodiments of this invention is selecting a subset of the combinations whose charge (price) does not exceed the user's budget. This subset includes those solutions which provide the best performance within the budgetary limit and those solutions which satisfy the technical requirements, but with the lowest prices.

With regard to computing the technical performance of selected combinations, another aspect of the embodiments of this invention is accommodating the fact that certain combinations of metal and supporting image can host the created solutions, but may not have the best technical performance in terms of, for example, throughput, overhead and reliability.

With regard to recommending the combinations with the best performance margin, another aspect of the embodiments of this invention involves recognizing that the derived set of solutions includes both cost effective solutions and higher capacity solutions having prices that can be near to the budgetary limit of the client.

Before continuing with the detailed description of the embodiments of this invention reference can be made to FIG. 1 for showing a block diagram of one suitable embodiment of a system 10 that is capable of implementing the embodiments of this invention. System 10 can be assumed to be associated with a cloud platform provider/vendor/source and includes at least one data processor (DP) 12 containing at least one CPU that is connected with at least one memory 14, such as one or more of semiconductor-based memory and disk-based memory, that stores computer program code or software (SW) 16. The SW 16, when executed by the at least one data processor 12, results in performance of operations that implement the methods of this invention. Also connected to the data processor 12 is at least one interface (IF) 18 through which a user, also referred to herein as a client, can interact with the system 10 via a suitable user terminal 18A. The interface 18 can be a network interface such as one or both of a local area network (LAN), including a wireless LAN (WLAN), or a wide area network (WAN), including the internet, and preferably implements a user interface (UI) via the SW 16 with the client such as by the use of drop-down menus (e.g., boxes) and/or any suitable UI screens, etc. Also connected with the data processor 12 can be at least one database 20 that stores at least a catalog 22 of available Cloud platform hardware and software that is capable of being configured based on the user's needs and budgetary constraints as will be detailed in FIG. 2. The database 20 can also store what will be referred to as templates 24 or bundled topologies (e.g., ‘best practice topology templates’). In general the SW 16 operates with catalog 22 and other information, including the templates 24 which can be stored in the database 20, to implement the embodiments of this invention.

It should be noted that the actual cloud platform hardware and software (e.g., CPUs, storage devices, database managers, operating systems, etc.) could be co-located with the system 10, or it could be physically present at some other location, or it could in actuality be widely distributed over a number of locations. The actual implementation and location or locations of the instantiations of the underlying cloud platfoim hardware and software is not particularly germane to the description of the embodiments of this invention.

FIG. 2 is a logic flow diagram that shows the operation of a method of this invention. Briefly, the method implements a multi-step solution composition and benchmarking process that can be characterized as follows.

2A. Solution deployment model input is comprised of inputting from the client mainly functional requirements: e.g., a functional specification (e.g., response time), number of persons (e.g., customers) to be simultaneously supported.

2B. Non-functional requirements are also input from the client, which can include: constraints: e.g., price constraints, license capacity; and any high availability (HA) requirements: e.g., avoidance of single point of failure, percentage of time the solution must be operational (e.g., 24/7, normal business hours only, etc.) Such high availability requirements can also be referred to as “resiliency requirements” of the client/user.

The system 10 generates a customized topology based on the client's specific requirements. This can involve the following:

• • (2C) based on the client's specific requirements, choosing best-practice topologies (from the templates 24 in database 20) as working templates, for example, cloud specific resource sizes can be applied to the model to identify potential deployment topologies that satisfy the capacity targets, and each tier of resources has each compute size applied thereto;
  • (2D) technically validating the template topologies against the client's requirements; and
  • (2E) generating customized topologies by varying the combinations of software and underlying infrastructure support in the template topologies and expanding the topology design to meet any HA requirements. For example, combinations of tiers are estimated and resource counts are identified when possible in this step.

2H. If a valid topology has been identified at this point the client uploads software and workloads. The software can be considered as the client's own application code, i.e., a client application to be deployed on the eventually configured cloud platform. This type of software is sometimes referred to as “ear files”.

2I. The system 10 benchmarks (e.g., the system 10 validates, assesses and/or tests) the capacity of the customized topology or topologies. This can involve:

• • (1) using a workload generator (e.g., such as a conventional workload generator application), generating different workloads for measuring the different bundling in the topologies;
  • (2) deploying the client uploaded software and workloads on top of the topologies and testing the topologies with the deployed software and workloads; and
  • (3) testing both the horizontal/vertical scaling capabilities and HA requirements. Horizontal scaling involves adding more nodes to a system, for example, scaling out from one Web server system to three, while vertical scaling means adding resources to a single node in a system.

Describing FIG. 2 now in more detail, at block 2A: a solution deployment model is input into a planner that forms a part of the software 16. At block 2B the client requirements, including price, capacity and HA targets are input into the planner via the interface 18 shown in FIG. 1. The client can be prompted via the UI to enter, for example, the client's budgetary and technical requirements as well as the workloads and software. At block 2C, based on client's specific requirements, the method chooses at least one of the best-practice topologies as a template (a working template). At block 2D the method technically validates the template topologies against the client's requirements. At block 2E the method generates customized topologies. At block 2F a determination is made if there are there any valid cloud topologies that are available to meet the client's requirements. If the result of the determination is negative at block 2G a determination is made if the failure to arrive at a valid topology was due to user input or internal target data. In the case of user input data control passes to block 2G1 to request the client to enter a new capacity target, while if the failure to arrive at a valid topology was due to internal target data control passes to block 2G2 to create a new capacity target to attempt a best fit to the client's budget. Note that if one or more of the iterations through this loop are unsuccessful the client may be informed that the client's performance goals are not compatible with, for example, the client's budgetary constraints and/or high availability (HA) requirements/expectations, or with the capabilities of the particular cloud platform provider to prove the requested service within the client's budgetary and other requirements. In either the case of block 2G1 or 2G2 control passes back to block 2B.

Assuming now that the determination at block 2F is positive (i.e., there is at least one valid cloud platform topology) control passes to block 2H to prompt the client via the UI to upload via the network interface 18 the client software and workloads and to receive same. At block 2I capacity benchmarking (evaluation, assessment and testing) is performed. Next, both pricing and license constraints are taken into account. This entails, for example, at block 2J applying pricing (cost) metrics to the Cloud platform resources for each potential topology. At block 2K there is a step of identifying a base compute cost, for example, per resource support costs, an operating system (OS) cost and more generally computing charges. At block 2L the system 10 identifies any software license charges per resource by CPU count, user count (additional input solicited), or other configurations. At block 2M the system 10 totals the resource and software charges across the topology for the estimated price. At block 2N there is a determination as to whether there are any valid topologies thus evaluated whose prices (cost to the client) are within the budget of the client. If the determination is negative, control passes to block 2O to request from the client a new capacity, price or HA target due to lack of a viable cloud based solution. If the determination at block 2N is affirmative control passes to block to 2P to identify a most cost effective topology. At block 2Q a determination is made if the price (cost to the client) computed thus far is more than some policy set percentage less than the goal (identified maximum cost). If yes, control passes back to block 2G2 to create the new capacity target via interaction with the client, otherwise control passes to block 2R to present what is the currently most cost effective topology and, when available, a higher capacity option that is also within the client's budgetary constraints. At this point the client has the opportunity to select a cloud based solution from one or more potential cloud based solutions, as it can be assumed that at least one offered topology satisfies the requirements of the client.

One non-limiting specific embodiment of an aspect of this invention is shown in FIG. 3. The embodiment provides at least for optimized resolutions in maintenance services. The Item 1 represents a process of collecting offline from one or more subject matter experts (Domain Experts) the following items: Item 2, rules concerning best practices bundled topologies and templates (e.g., stored in database 20); Item 3, costs related to the hardware and software products supported in the best practices templates; Item 4, constraints that reflect the best practices configuration templates supported by a specific service provider.

Item 2 can be implemented or represented as the database entry, such as a collection of files, or a file resource that stores rules about best practices bundle topology templates. Non-limiting examples of bundles topology rules are, for example:

• • IF an application requires more disk space than available on the selected VM (virtual machine), THEN add more disk space to the existing VM, or replace with a VM having a larger disk space, and/or add a storage area network (SAN) to the VM, and/or
  • IF CPU requirement reaches 80%, THEN add more CPU to the existing VM, or add a new VM, or migrate the application to another VM with more CPU capacity.

Those skilled in the art should appreciate, however, that these are only examples of action rules and that any rule(s) may be used without departing from the embodiments of the present invention.

Item 3 represents a database (e.g., database 20), a collection of files, or a file resource that stores costs related to the products involved in the best practices topologies determined in Item 4. Examples of such costs are product cost, installation cost, cost of the necessary configuration to work with required products, cost of generated downtime, etc.

Item 4 represents a database (e.g., database 20), a collection of files, or a file resource that stores constraints and dependencies that reflect the best practices bundle templates supported by a specific service provider (e.g., the provider of the cloud platform). Examples of constraints that reflect best practices configurations include, for example: “Web application server M version a.b.c works with database server N version x.y.z”; “Web application server M version a.b.c works on version 9.1 of OS of SW Provider N”.

A special type of configuration constraints are classes of equivalence rules that indicate which products provide similar functionality. Examples of classes of equivalence rules are: “Web application servers are: Web application server-1, Web application server-2, . . . , Web application server-n, “; and database application servers are: Database application server-1, Database application server-2, . . . , Database application server-n.

Software conflicts are another potential type of constraint. Examples of software conflicts constraints are: “Intrusion Protection Software A is unstable on Operating System B”; “Application server A on Operating System B conflicts with Web services manager C”.

Those skilled in the art will appreciate, however, that these are only non-limiting examples of constraints and that any IT constraints and dependencies may be used without departing from the embodiments of the present invention.

It should also be appreciated that the “Expert” shown in Item 1 could be one or more human experts (e.g., one or more IT professionals), or that the “Expert” shown in Item 1 could be one or more “software” experts, such as one or more computer programs, such as an ‘expert system’, designed to incorporate the knowledge, expertise and decision-making rationale of one or more of such human experts.

Item 5 represents the customer, client or any personnel selecting for the customer the products and products bundles expressed as the set of requirements (Item 6). In a certain non-limiting embodiment the selected bundle is a multi-tiered e-commerce system that the client wishes in order to implement a particular business model. Such an exemplary e-commerce system can include the following subsystems connected by local and wide area networks: web based presentation systems, access systems, application business logic, messaging systems, database systems and storage subsystems—running on top of operating system(s) and specific hardware. In this example the client needs to determine what are the possible service options that accommodate the performance, the over-all service availability, and the SLAs (service level agreements) expressed in the business and IT requirements (item 6) and that are also cost effective for the client in the context of the cloud platform.

Item 6 represents a set of requirements that is input by the client to express a desired service/bundle. In a particular embodiment these can be expressed as drop-down lists of available options or as free text (depending on the specifics of the implemented user interface of the system 10) followed by the search in the bundled topologies database (Item 1).

Item 7 represents a process of generating the optimal bundle topology(ies) (see Item 8) for the client customer. Examples of steps to accomplish this process of Item 7 are detailed in the process diagram of FIG. 2. In general the technical evaluation of each potential topology is paired with the total cost of the solution including the installation cost and the operational cost. The costs can be computed using data stored in Item 3. The benefit of each potential bundle topology can then be calculated and the performance versus cost comparison can be provided to the client via the interface 18 for comparison and selection.

Item 8 represents a list of possible bundle options that accommodate the requirements (Item 6). Item 8 shows a process to allow the client to send feedback (Item 8′) to the cloud platform provider with additional requirements when the bundle options in Item 9 do not lead to a final selection by the client. The additional requirements can be additional non-functional requirements (NFR) or new functional requirements. Upon receipt of the additional requirements the Domain Expert (Item 1) may enhance the topology repository to reflect the customer's requirements. This action can trigger a new search against the updated set of client requirements resulting in a new list of possible bundles options.

Item 9 represents a final cloud platform resource (hardware/software) bundle selection of the client.

The use of the exemplary embodiments of this invention provides a balance between cost and performance in selecting an instantiation of resources from a cloud platform. The exemplary embodiments enable a determination to be made if a cloud platform tool requests information related to a budget of a user (client) and technical requirements for a cloud platform solution needed by the client, as well as workloads and software from the client.
