The present invention relates generally to the field of data processing, and more particularly to reducing resource utilization in cloud-based data services.
In computing, data transformation is the process of converting data from one format or structure into another format or structure and is a fundamental aspect of most data integration and data management tasks. Data transformation can be simple or complex based on the required changes to the data between the source (initial) data and the target (final) data. Data transformation can be performed via a mixture of manual and automated steps. Tools and technologies used for data transformation can vary widely based on the format, structure, complexity, and volume of the data being transformed. Data transformation can be divided into various steps, each applicable as needed based on the complexity of the transformation required, for example, data discovery, data mapping, code generation, code execution, and data review. The steps are often the focus of developers or technical data analysts who may use multiple specialized tools to perform the tasks.
A machine learning pipeline is used to help automate machine learning workflows. The machine learning pipeline operates by enabling a sequence of data to be transformed and correlated together in a model that can be tested and evaluated to achieve an outcome, whether positive or negative. As the word ‘pipeline’ suggests, a machine learning pipeline is a series of steps chained together in the machine learning cycle that may involve obtaining the data, processing the data, training and testing on various machine learning algorithms, and, finally, obtaining some output, for example, a prediction.
Embodiments of the present invention disclose a method, a computer program product, and a system for reducing resource utilization in cloud-based data services. The method may include one or more computer processors selecting a dataset for upload to a server. One or more computer processors determine a data transformation scheduled to be applied to the dataset by the server. One or more computer processors perform a dataset read on the dataset. One or more computer processors perform the data transformation on the dataset. One or more computer processors upload the transformed dataset to the server.
Many cloud-based services, for example, machine learning cloud-based services, rely on uploaded data files, i.e., datasets, in various formats, such as a comma-separated values (CSV) file format. Often, upon uploading a dataset, the cloud-based service applies one or more data transformation steps. For example, machine learning pipelines contain transformation steps applied to each new data file as the file is uploaded. If a dataset is large, then the upload can take a significant amount of time and resources. In addition, a user may be charged for storage utilization, which can be more costly than necessary if the cloud-based service does not use the entire dataset. Embodiments of the present invention recognize that efficiency of cloud-based service resource utilization may be gained by performing one or more data transformations on the client side prior to uploading the dataset to the cloud-based service. By performing data transformations on the client side, upload time, network usage, and storage usage on the server side are reduced. In addition, if storage usage is reduced, the charges to the user may also be reduced. Implementation of embodiments of the invention may take a variety of forms, and exemplary implementation details are discussed subsequently with reference to the Figures.

For example, client computing device 104 may be a heads-up display in the windshield of the vehicle. In general, client computing device 104 represents one or more programmable electronic devices or combination of programmable electronic devices capable of executing machine readable program instructions and communicating with server computer 108 and other computing devices (not shown) within distributed data processing environment 100 via a network, such as network 102. Client computing device 104 includes data transformation program 106. Client computing device 104 may include internal and external hardware components, as depicted and described in further detail with respect to
Data transformation program 106 performs data transformations on datasets on the client side of distributed data processing environment 100 such that the transformations are not performed on the server side, which can reduce upload time, network usage, and storage usage. Data transformation program 106 selects a dataset file to upload to cloud-based service 110. Data transformation program 106 determines what data transformations are planned to be applied to the selected dataset by cloud-based service 110. Data transformation program 106 performs a dataset read on the selected dataset. Data transformation program 106 determines metadata of the selected dataset. Data transformation program 106 performs one or more data transformations on the selected dataset. Data transformation program 106 uploads the transformed dataset to cloud-based service 110. In an embodiment, data transformation program 106 represents JavaScript® code executed directly on a web browser (not shown). (Java and all Java-based trademarks and logos are trademarks or registered trademarks of Oracle and/or its affiliates.) Data transformation program 106 is depicted and described in further detail with respect to
Server computer 108 can be a standalone computing device, a management server, a web server, a mobile computing device, or any other electronic device or computing system capable of receiving, sending, and processing data. In other embodiments, server computer 108 can represent a server computing system utilizing multiple computers as a server system, such as in a cloud computing environment. In another embodiment, server computer 108 can be a laptop computer, a tablet computer, a netbook computer, a personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, or any programmable electronic device capable of communicating with client computing device 104 and other computing devices (not shown) within distributed data processing environment 100 via network 102. In another embodiment, server computer 108 represents a computing system utilizing clustered computers and components (e.g., database server computers, application server computers, etc.) that act as a single pool of seamless resources when accessed within distributed data processing environment 100. Server computer 108 includes cloud-based service 110 and server database 112.
Cloud-based service 110 is one or more of a plurality of software entities that uses data to provide a service to one or more users over a network, such as network 102. A cloud service is any service made available to users on demand via the Internet from a cloud computing provider's server as opposed to being provided from a company's own on-premises servers. Cloud-based services are designed to provide easy, scalable access to applications, resources and services, and are fully managed by a cloud services provider. In an embodiment, cloud-based service 110 is a machine learning service. In other embodiments, cloud-based service 110 may be a storage service (e.g., a database), a computation service (e.g., a virtual machine or a docker container), a message queue service, etc.
Server database 112 is a repository for data used and transformed by data transformation program 106. Server database 112 can represent one or more databases. In the depicted embodiment, server database 112 resides on server computer 108. In another embodiment, server database 112 may reside elsewhere within distributed data processing environment 100, provided data transformation program 106 has access to server database 112. A database is an organized collection of data. Server database 112 can be implemented with any type of storage device capable of storing data and configuration files that can be accessed and utilized by data transformation program 106, such as a database server, a hard disk drive, or a flash memory. Server database 112 stores data uploaded by data transformation program 106 as well as any additional data used by cloud-based service 110. Server database 112 may also store one or more lists of dataset transformations required for one or more datasets.
The present invention may contain various accessible data sources, such as server database 112, that may include personal data, content, or information the user wishes not to be processed. Personal data includes personally identifying information or sensitive personal information as well as user information, such as tracking or geolocation information. Processing refers to any operating, automated or unautomated, or set of operations such as collecting, recording, organizing, structuring, storing, adapting, altering, retrieving, consulting, using, disclosing by transmission, dissemination, or otherwise making available, combining, restricting, erasing, or destroying personal data. In an embodiment, data transformation program 106 enables the authorized and secure processing of personal data. Data transformation program 106 provides informed consent, with notice of the collection of personal data, allowing the user to opt in or opt out of processing personal data. Consent can take several forms. Opt-in consent can impose on the user to take an affirmative action before personal data is processed. Alternatively, opt-out consent can impose on the user to take an affirmative action to prevent the processing of personal data before personal data is processed. Data transformation program 106 provides information regarding personal data and the nature (e.g., type, scope, purpose, duration, etc.) of the processing. Data transformation program 106 provides the user with copies of stored personal data. Data transformation program 106 allows the correction or completion of incorrect or incomplete personal data. Data transformation program 106 allows the immediate deletion of personal data.
Data transformation program 106 selects a dataset file for upload (step 202). In one embodiment, data transformation program 106 receives a selection of a dataset file from a user of client computing device 104. In another embodiment, data transformation program 106 may receive a list of one or more dataset files to select from a user of client computing device 104 via a user interface (not shown). In an embodiment, data transformation program 106 can select, or propose to a user of client computing device 104, a dataset file or format based on previous user selections. In another embodiment, data transformation program 106 selects a dataset file for upload based on a pre-defined list of files for upload. In the embodiment, the pre-defined list of files may be stored on server database 112. In an embodiment where cloud-based service 110 is a machine learning pipeline, data transformation program 106 selects a new data file to input to cloud-based service 110.
Data transformation program 106 determines transformations to be applied to the selected dataset (step 204). In an embodiment, data transformation program 106 communicates with cloud-based service 110 to determine which transformations cloud-based service 110 plans to perform on, i.e., are scheduled to be performed on or applied to, the selected dataset file. In another embodiment, data transformation program 106 may receive a list of one or more data transformations, or a set of data transformations, from a user of client computing device 104 via a user interface (not shown). Data transformations may include, but are not limited to, removal of columns, removal of rows, filtering of columns, filtering of rows, deidentification, deduplication, compression, transcoding, encryption, logarithmic transformation, square root, multiplicative inverse transformation, ranked transformation, Fischer transformation, Laplace transformation, and Box-cox transformation.
Data transformation program 106 performs a dataset read (step 206). In an embodiment, data transformation program 106 performs a memory non-intensive dataset read on the selected dataset file. By performing a memory non-intensive dataset read, data transformation program 106 does not load the full dataset into memory but reads and processes the data in chunk and/or stream form, thereby not impacting memory utilization of client computing device 104. In an embodiment, data transformation program 106 performs the memory non-intensive dataset read with a web browser (not shown) using JavaScript® code. In another embodiment, data transformation program 106 may perform the dataset read using a browser plugin or special software installed on client computing device 104 (not shown), which may be written in any programming language. In an embodiment, data transformation program 106 performs a data pass while performing the dataset read, i.e., reading all rows of data for at least one column in the dataset. For example, if data transformation program 106 determines a data transformation of filtering rows will be applied to the dataset, such as keeping rows with a value greater than 1980 in a year column, then data transformation program 106 performs a data pass to ready the values in the year column.
Data transformation program 106 determines metadata of the selected dataset (step 208). In an embodiment, data transformation program 106 determines metadata associated with the selected dataset based on the one or more transformations determined in step 204. Metadata may include, but is not limited to, a number of rows in the dataset, a number of columns in the dataset, and column types. For example, if data transformation program 106 determines a data transformation of removing a particular column from the dataset, then data transformation program 106 uses the metadata to determine whether that column is present in the dataset.
Data transformation program 106 performs a dataset transformation (step 210). In an embodiment, data transformation program 106 performs one or more simple data transformations on the selected dataset file. A simple data transformation is one that does not impact performance of client computing device 104. For example, data transformation program 106 may perform a data transformation such as removing one or more columns from the dataset file that will not be used by cloud-based service 110. Other examples of simple data transformations include, but are not limited to, removal of rows, filtering of columns, filtering of rows, replacing values in columns and/or rows, and renaming columns and/or rows. In another embodiment, data transformation program 106 may perform more complex data transformations in order to limit the use of resources on server computer 108, i.e., upload time, network usage, storage usage, etc. In an embodiment, data transformation program 106 determines which of the one or more data transformations scheduled to be performed by cloud-based service 110 are simple transformations, such that data transformation program 106 can determine which data transformations to perform. In an embodiment, data transformation program 106 performs the data transformation “on the fly,” during an upload process. In the embodiment, a user of client computing device 104 does not have to wait for data transformation program 106 to complete the data transformation before the upload step. In an embodiment, data transformation program 106 may perform the data transformation on the full dataset file, or on a chunk or stream of the dataset file, as would be recognized by one of skill in the art.
Data transformation program 106 uploads the transformed dataset (step 212). In an embodiment, data transformation program 106 uploads the transformed dataset directly to cloud-based service 110. In another embodiment, data transformation program 106 uploads the transformed dataset to server database 112 such that cloud-based service 110 can retrieve the transformed dataset file from server database 112 when needed. For example, if cloud-based service 110 is a machine learning pipeline, then cloud-based service 110 can retrieve the transformed dataset at a particular step in a sequence of steps. In the example, data transformation program 106 may perform one or more data transformations and upload the transformed dataset to cloud-based service 110. Then cloud-based service 110 performs actions such as calculations and/or creation of new data, after which additional data transformations, such as removal of one or more rows, are needed. A user can modify cloud-based service 110 such that communication is made to data transformation program 106 to perform the additional data transformations, e.g., the removal of rows, prior to the upload, thereby reducing additional resource usage by cloud-based service 110. In an embodiment where cloud-based service 110 is a machine learning pipeline, after data transformation program 106 uploads the transformed dataset, cloud-based service 110 performs checks and data transformations, where one or more required transformations were already performed by data transformation program 106. In the embodiment, cloud-based service 110 performs those data transformations anyway, but no changes in the dataset result. In the embodiment, no modifications to cloud-based service 110 are needed. In another embodiment, where cloud-based service 110 is a machine learning pipeline, data transformation program 106 provides information to cloud-based service 110 regarding the data transformations already performed by data transformation program 106, and cloud-based service 110 skips those data transformation steps.
Client computing device 104 can include processor(s) 304, cache 314, memory 306, persistent storage 308, communications unit 310, input/output (I/O) interface(s) 312 and communications fabric 302. Communications fabric 302 provides communications between cache 314, memory 306, persistent storage 308, communications unit 310, and input/output (I/O) interface(s) 312. Communications fabric 302 can be implemented with any architecture designed for passing data and/or control information between processors (such as microprocessors, communications and network processors, etc.), system memory, peripheral devices, and any other hardware components within a system. For example, communications fabric 302 can be implemented with one or more buses.

In general, memory 306 can include any suitable volatile or non-volatile computer readable storage media. Cache 314 is a fast memory that enhances the performance of processor(s) 304 by holding recently accessed data, and data near recently accessed data, from memory 306.
Program instructions and data used to practice embodiments of the present invention, e.g., data transformation program 106 are stored in persistent storage 308 for execution and/or access by one or more of the respective processor(s) 304 of client computing device 104 via cache 314. In this embodiment, persistent storage 308 includes a magnetic hard disk drive. Alternatively, or in addition to a magnetic hard disk drive, persistent storage 308 can include a solid-state hard drive, a semiconductor storage device, a read-only memory (ROM), an erasable programmable read-only memory (EPROM), a flash memory, or any other computer readable storage media that is capable of storing program instructions or digital information.
The media used by persistent storage 308 may also be removable. For example, a removable hard drive may be used for persistent storage 308. Other examples include optical and magnetic disks, thumb drives, and smart cards that are inserted into a drive for transfer onto another computer readable storage medium that is also part of persistent storage 308.
Communications unit 310, in these examples, provides for communications with other data processing systems or devices, including resources of server computer 108. In these examples, communications unit 310 includes one or more network interface cards. Communications unit 310 may provide communications through the use of either or both physical and wireless communications links.

I/O interface(s) 312 allows for input and output of data with other devices that may be connected to client computing device 104. For example, I/O interface(s) 312 may provide a connection to external device(s) 316 such as a keyboard, a keypad, a touch screen, a microphone, a digital camera, and/or some other suitable input device. External device(s) 316 can also include portable computer readable storage media such as, for example, thumb drives, portable optical or magnetic disks, and memory cards. Software and data used to practice embodiments of the present invention, e.g., data transformation program 106, can be stored on such portable computer readable storage media and can be loaded onto persistent storage 308 via I/O interface(s) 312. I/O interface(s) 312 also connect to a display 318.
Display 318 provides a mechanism to display data to a user and may be, for example, a computer monitor. Display 318 can also function as a touch screen, such as a display of a tablet computer.
It is to be understood that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported, providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure that includes a network of interconnected nodes.
