The ability of customers of data processing services, including cloud and edge services, to switch from one data processing service to another while maintaining a minimum functionality of service and without downtime of services, or to use the services of several providers simultaneously without undue obstacles and data transfer costs, is a key condition for a more competitive market with lower entry barriers for new providers of data processing services, and for ensuring further resilience for the users of those services. Customers benefiting from free-tier offerings should also benefit from the provisions for switching that are laid down in this Regulation, so that those offerings do not result in a lock-in situation for customers.

Regulation (EU) 2018/1807 of the European Parliament and of the Council encourages providers of data processing services to develop and effectively implement self-regulatory codes of conduct covering best practices for, inter alia, facilitating the switching of providers of data processing services and the porting of data. Given the limited uptake of the self-regulatory frameworks developed in response, and the general unavailability of open standards and interfaces, it is necessary to adopt a set of minimum regulatory obligations for providers of data processing services to eliminate pre-commercial, commercial, technical, contractual and organisational obstacles, which are not limited to reduced speed of data transfer at the customer’s exit, which hamper effective switching between data processing services.

Digital assets refer to elements in digital form for which the customer has the right of use, including applications and metadata related to the configuration of settings, security, and access and control rights management, and other elements such as manifestations of virtualisation technologies, including virtual machines and containers. Digital assets can be transferred where the customer has the right of use independent of the contractual relationship with the data processing service it intends to switch from. Those other elements are essential for the effective use of the customer’s data and applications in the environment of the destination provider of data processing services.

This Regulation aims to facilitate switching between data processing services, which encompasses conditions and actions that are necessary for a customer to terminate a contract for a data processing service, to conclude one or more new contracts with different providers of data processing services, to port its exportable data and digital assets, and where applicable, benefit from functional equivalence.

Switching is a customer-driven operation consisting of several steps, including data extraction, which refers to the downloading of data from the ecosystem of the source provider of data processing services; transformation, where the data is structured in a way that does not match the schema of the target location; and the uploading of the data in a new destination location. In a specific situation outlined in this Regulation, unbundling of a particular service from the contract and moving it to a different provider should also be considered to be switching. The switching process is sometimes managed on behalf of the customer by a third-party entity. Accordingly, all rights and obligations of the customer established by this Regulation, including the obligation to cooperate in good faith, should be understood to apply to such a third-party entity in those circumstances. Providers of data processing services and customers have different levels of responsibilities, depending on the steps of the process referred to. For instance, the source provider of data processing services is responsible for extracting the data to a machine-readable format, but it is the customer and the destination provider of data processing services who are to upload the data to the new environment, unless a specific professional transition service has been obtained. A customer who intends to exercise rights related to switching, which are provided for in this Regulation, should inform the source provider of data processing services of the decision to either switch to a different provider of data processing services, switch to an on-premises ICT infrastructure or to delete that customer’s assets and erase its exportable data.

Functional equivalence means re-establishing, on the basis of the customer’s exportable data and digital assets, a minimum level of functionality in the environment of a new data processing service of the same service type after switching, where the destination data processing service delivers a materially comparable outcome in response to the same input for shared features supplied to the customer under the contract. Providers of data processing services can only be expected to facilitate functional equivalence for the features that both the source and destination data processing services offer independently. This Regulation does not constitute an obligation to facilitate functional equivalence for providers of data processing services other than those offering services of the IaaS delivery model.

Providers of data processing services should also be required to remove existing obstacles and not impose new ones, including for customers wishing to switch to an on-premises ICT infrastructure. Obstacles can, inter alia, be of a pre-commercial, commercial, technical, contractual or organisational nature. Providers of data processing services should also be required to remove obstacles to unbundling a specific individual service from other data processing services provided under a contract and make the relevant service available for switching, in the absence of major and demonstrated technical obstacles that prevent such unbundling.

To facilitate interoperability and switching between data processing services, users and providers of data processing services should consider the use of implementation and compliance tools, in particular those published by the Commission in the form of an EU Cloud Rulebook and a Guidance on public procurement of data processing services. In particular, standard contractual clauses are beneficial because they increase confidence in data processing services, create a more balanced relationship between users and providers of data processing services and improve legal certainty with regard to the conditions that apply for switching to other data processing services. In that context, users and providers of data processing services should consider the use of standard contractual clauses or other self-regulatory compliance tools provided that they fully comply with this Regulation, developed by relevant bodies or expert groups established under Union law.

Data processing services should cover services that allow ubiquitous and on-demand network access to a configurable, scalable and elastic shared pool of distributed computing resources. Those computing resources include resources such as networks, servers or other virtual or physical infrastructure, software, including software development tools, storage, applications and services. The capability of the customer of the data processing service to unilaterally self-provision computing capabilities, such as server time or network storage, without any human interaction by the provider of data processing services could be described as requiring minimal management effort and as entailing minimal interaction between provider and customer. The term ‘ubiquitous’ is used to describe the computing capabilities provided over the network and accessed through mechanisms promoting the use of heterogeneous thin or thick client platforms (from web browsers to mobile devices and workstations). The term ‘scalable’ refers to computing resources that are flexibly allocated by the provider of data processing services, irrespective of the geographical location of the resources, in order to handle fluctuations in demand. The term ‘elastic’ is used to describe those computing resources that are provisioned and released according to demand in order to rapidly increase or decrease resources available depending on workload. The term ‘shared pool’ is used to describe those computing resources that are provided to multiple users who share a common access to the service, but where the processing is carried out separately for each user, although the service is provided from the same electronic equipment. The term ‘distributed’ is used to describe those computing resources that are located on different networked computers or devices and which communicate and coordinate among themselves by message passing. The term ‘highly distributed’ is used to describe data processing services that involve data processing closer to where data are being generated or collected, for instance in a connected data processing device. Edge computing, which is a form of such highly distributed data processing, is expected to generate new business models and cloud service delivery models, which should be open and interoperable from the outset.

The generic concept ‘data processing services’ covers a substantial number of services with a very broad range of different purposes, functionalities and technical set-ups. As commonly understood by providers and users and in line with broadly used standards, data processing services fall into one or more of the following three data processing service delivery models, namely Infrastructure as a Service (IaaS), Platform as a service (PaaS) and Software as a Service (SaaS). Those service delivery models represent a specific, pre-packaged combination of ICT resources offered by a provider of data processing service. Those three fundamental data processing delivery models are further complemented by emerging variations, each comprised of a distinct combination of ICT resources, such as Storage as a Service and Database as a Service. Data processing services can be categorised in a more granular way and divided into a non-exhaustive list of sets of data processing services that share the same primary objective and main functionalities as well as the same type of data processing models, that are not related to the service’s operational characteristics (same service type). Services falling under the same service type may share the same data processing service model, however, two databases might appear to share the same primary objective, but after considering their data processing model, distribution model and the use cases that they are targeted at, such databases could fall into a more granular subcategory of similar services. Services of the same service type may have different and competing characteristics such as performance, security, resilience, and quality of service.

Providers of data processing services should be required to offer all the assistance and support within their capacity, proportionate to their respective obligations, that is required to make the switching process to a service of a different provider of data processing services successful, effective and secure. This Regulation does not require providers of data processing services to develop new categories of data processing services, including within, or on the basis of, the ICT infrastructure of different providers of data processing services in order to guarantee functional equivalence in an environment other than their own systems. A source provider of data processing services does not have access to or insights into the environment of the destination provider of data processing services. Functional equivalence should not be understood to oblige the source provider of data processing services to rebuild the service in question within the infrastructure of the destination provider of data processing services. Instead, the source provider of data processing services should take all reasonable measures within its power to facilitate the process of achieving functional equivalence through the provision of capabilities, adequate information, documentation, technical support and, where appropriate, the necessary tools.

Undermining the extraction of the exportable data that belongs to the customer from the source provider of data processing services can impede the restoration of the service functionalities in the infrastructure of the destination provider of data processing services. In order to facilitate the customer’s exit strategy, avoid unnecessary and burdensome tasks and to ensure that the customer does not lose any of their data as a consequence of the switching process, the source provider of data processing services should inform the customer in advance of the scope of the data that can be exported once that customer decides to switch to a different service provided by a different provider of data processing services or to move to an on-premises ICT infrastructure. The scope of exportable data should include, at a minimum, input and output data, including metadata, directly or indirectly generated, or cogenerated, by the customer’s use of the data processing service, excluding any assets or data of the provider of data processing services or a third party. The exportable data should exclude any assets or data of the provider of data processing services or of the third party that are protected by intellectual property rights or constituting trade secrets of that provider or of that third party, or data related to the integrity and security of the service, the export of which will expose the providers of data processing services to cybersecurity vulnerabilities. Those exemptions should not impede or delay the switching process.

Data processing services are used across sectors and vary in complexity and service type. This is an important consideration with regard to the porting process and timeframes. Nonetheless, an extension of the transitional period on the grounds of technical unfeasibility to allow the finalisation of the switching process in the given timeframe should be invoked only in duly justified cases. The burden of proof in that regard should fall fully on the provider of the data processing service concerned. This is without prejudice to the exclusive right of the customer to extend the transitional period once for a period that the customer considers to be more appropriate for its own purposes. The customer may evoke that right to an extension prior to or during the transitional period, taking into account that the contract remains applicable during the transitional period.

Switching charges are charges imposed by providers of data processing services on the customers for the switching process. Typically, those charges are intended to pass on costs which the source provider of data processing services may incur because of the switching process to the customer who wishes to switch. Common examples of switching charges are costs related to the transit of data from one provider of data processing services to another or to an on-premises ICT infrastructure (data egress charges) or the costs incurred for specific support actions during the switching process. Unnecessarily high data egress charges and other unjustified charges unrelated to actual switching costs inhibit customers from switching, restrict the free flow of data, have the potential to limit competition and cause lock-in effects for the customers by reducing incentives to choose a different or additional service provider. Switching charges should therefore be abolished after three years from the date of entry into force of this Regulation. Providers of data processing services should be able to impose reduced switching charges up to that date.

A source provider of data processing services should be able to outsource certain tasks and compensate third-party entities in order to comply with the obligations provided for in this Regulation. A customer should not bear the costs arising from the outsourcing of services concluded by the source provider of data processing services during the switching process and such costs should be considered to be unjustified unless they cover work undertaken by the provider of data processing services at the customer’s request for additional support in the switching process which goes beyond the switching obligations of the provider as expressly provided for in this Regulation. Nothing in this Regulation prevents a customer from compensating third-party entities for support in the migration process or parties from agreeing on contracts for data processing services of a fixed duration, including proportionate early termination penalties to cover the early termination of such contracts, in accordance with Union or national law. In order to foster competition, the gradual withdrawal of the charges associated with switching between different providers of data processing services should specifically include data egress charges imposed by a provider of data processing services on a customer. Standard service fees for the provision of the data processing services themselves are not switching charges. Those standard service fees are not subject to withdrawal and remain applicable until the contract for the provision of the relevant services ceases to apply. This Regulation allows the customer to request the provision of additional services that go beyond the provider’s switching obligations under this Regulation. Those additional services, can be performed and charged for by the provider when they are performed at the customer’s request and the customer agrees to the price of those services in advance.

Throughout the switching process, a high level of security should be maintained. This means that the source provider of data processing services should extend the level of security to which it committed for the service to all technical arrangements for which such provider is responsible during the switching process, such as network connections or physical devices. Existing rights relating to the termination of contracts, including those introduced by Regulation (EU) 2016/679 and Directive (EU) 2019/770 of the European Parliament and of the Council should not be affected. This Regulation should not be understood to prevent a provider of data processing services from providing to customers new and improved services, features and functionalities or from competing with other providers of data processing services on that basis.

To facilitate interoperability and switching between data processing services, users and providers of data processing services should consider the use of implementation and compliance tools, in particular those published by the Commission in the form of an EU Cloud Rulebook and a Guidance on public procurement of data processing services. In particular, standard contractual clauses are beneficial because they increase confidence in data processing services, create a more balanced relationship between users and providers of data processing services and improve legal certainty with regard to the conditions that apply for switching to other data processing services. In that context, users and providers of data processing services should consider the use of standard contractual clauses or other self-regulatory compliance tools provided that they fully comply with this Regulation, developed by relevant bodies or expert groups established under Union law.

Undermining the extraction of the exportable data that belongs to the customer from the source provider of data processing services can impede the restoration of the service functionalities in the infrastructure of the destination provider of data processing services. In order to facilitate the customer’s exit strategy, avoid unnecessary and burdensome tasks and to ensure that the customer does not lose any of their data as a consequence of the switching process, the source provider of data processing services should inform the customer in advance of the scope of the data that can be exported once that customer decides to switch to a different service provided by a different provider of data processing services or to move to an on-premises ICT infrastructure. The scope of exportable data should include, at a minimum, input and output data, including metadata, directly or indirectly generated, or cogenerated, by the customer’s use of the data processing service, excluding any assets or data of the provider of data processing services or a third party. The exportable data should exclude any assets or data of the provider of data processing services or of the third party that are protected by intellectual property rights or constituting trade secrets of that provider or of that third party, or data related to the integrity and security of the service, the export of which will expose the providers of data processing services to cybersecurity vulnerabilities. Those exemptions should not impede or delay the switching process.

The information to be provided by providers of data processing services to the customer could support the customer’s exit strategy. That information should include procedures for initiating switching from the data processing service; the machine-readable data formats to which the user’s data can be exported; the tools intended to export data, including open interfaces as well as information on compatibility with harmonised standards or common specifications based on open interoperability specifications; information on known technical restrictions and limitations that could have an impact on the switching process; and the estimated time necessary to complete the switching process.

In order to facilitate switching between data processing services, all parties involved, including both source and destination providers of data processing services, should cooperate in good faith to make the switching process effective, enable the secure and timely transfer of necessary data in a commonly used, machine-readable format, and by means of open interfaces, while avoiding service disruptions and maintaining continuity of the service.

Standardisation and semantic interoperability should play a key role to provide technical solutions to ensure interoperability within and among common European data spaces which are purpose or sector specific or cross-sectoral interoperable frameworks for common standards and practices to share or jointly process data for, inter alia, the development of new products and services, scientific research or civil society initiatives. This Regulation lays down certain essential requirements for interoperability. Participants in data spaces that offer data or data services to other participants, which are entities facilitating or engaging in data sharing within common European data spaces, including data holders, should comply with those requirements insofar as elements under their control are concerned. Compliance with those rules can be ensured by adhering to the essential requirements laid down in this Regulation, or presumed by complying with harmonised standards or common specifications via a presumption of conformity. In order to facilitate conformity with the requirements for interoperability, it is necessary to provide for a presumption of conformity of interoperability solutions that meet harmonised standards or parts thereof in accordance with Regulation (EU) No 1025/2012, which represents the framework by default to elaborate standards that provide for such presumptions. The Commission should assess barriers to interoperability and prioritise standardisation needs, on the basis of which it may request one or more European standardisation organisations, pursuant to Regulation (EU) No 1025/2012, to draft harmonised standards which satisfy the essential requirements laid down in this Regulation. Where such requests do not result in harmonised standards or such harmonised standards are insufficient to ensure conformity with the essential requirements of this Regulation, the Commission should be able to adopt common specifications in those areas provided that in so doing it duly respects the role and functions of standardisation organisations. Common specification should be adopted only as an exceptional fall-back solution to facilitate compliance with the essential requirements of this Regulation, or when the standardisation process is blocked, or when there are delays in the establishment of appropriate harmonised standards. Where a delay is due to the technical complexity of the standard in question, this should be considered by the Commission before contemplating the establishment of common specifications. Common specifications should be developed in an open and inclusive manner and take into account, where relevant, the advice of the European Data Innovation Board (EDIB) established by Regulation (EU) 2022/868. Additionally, common specifications in different sectors could be adopted, in accordance with Union or national law, on the basis of specific needs of those sectors. Furthermore, the Commission should be enabled to mandate the development of harmonised standards for the interoperability of data processing services.

Switching charges are charges imposed by providers of data processing services on the customers for the switching process. Typically, those charges are intended to pass on costs which the source provider of data processing services may incur because of the switching process to the customer who wishes to switch. Common examples of switching charges are costs related to the transit of data from one provider of data processing services to another or to an on-premises ICT infrastructure (data egress charges) or the costs incurred for specific support actions during the switching process. Unnecessarily high data egress charges and other unjustified charges unrelated to actual switching costs inhibit customers from switching, restrict the free flow of data, have the potential to limit competition and cause lock-in effects for the customers by reducing incentives to choose a different or additional service provider.

Digital assets refer to elements in digital form for which the customer has the right of use, including applications and metadata related to the configuration of settings, security, and access and control rights management, and other elements such as manifestations of virtualisation technologies, including virtual machines and containers. Digital assets can be transferred where the customer has the right of use independent of the contractual relationship with the data processing service it intends to switch from. Those other elements are essential for the effective use of the customer’s data and applications in the environment of the destination provider of data processing services.

This Regulation aims to facilitate switching between data processing services, which encompasses conditions and actions that are necessary for a customer to terminate a contract for a data processing service, to conclude one or more new contracts with different providers of data processing services, to port its exportable data and digital assets, and where applicable, benefit from functional equivalence.

Functional equivalence means re-establishing, on the basis of the customer’s exportable data and digital assets, a minimum level of functionality in the environment of a new data processing service of the same service type after switching, where the destination data processing service delivers a materially comparable outcome in response to the same input for shared features supplied to the customer under the contract. Providers of data processing services can only be expected to facilitate functional equivalence for the features that both the source and destination data processing services offer independently. This Regulation does not constitute an obligation to facilitate functional equivalence for providers of data processing services other than those offering services of the IaaS delivery model.

An ambitious and innovation-inspiring regulatory approach to interoperability is needed to overcome vendor lock-in, which undermines competition and the development of new services. Interoperability between data processing services involves multiple interfaces and layers of infrastructure and software and is rarely confined to a binary test of being achievable or not. Instead, the building of such interoperability is subject to a cost-benefit analysis which is necessary to establish whether it is worthwhile to pursue reasonably predictable results. The ISO/IEC 19941:2017 is an important international standard constituting a reference for the achievement of the objectives of this Regulation, as it contains technical considerations clarifying the complexity of such a process.

Where providers of data processing services are in turn customers of data processing services provided by a third-party provider, they will benefit from more effective switching themselves while simultaneously remaining bound by this Regulation’s obligations regarding their own service offerings.

Providers of data processing services should be required to offer all the assistance and support within their capacity, proportionate to their respective obligations, that is required to make the switching process to a service of a different provider of data processing services successful, effective and secure. This Regulation does not require providers of data processing services to develop new categories of data processing services, including within, or on the basis of, the ICT infrastructure of different providers of data processing services in order to guarantee functional equivalence in an environment other than their own systems. A source provider of data processing services does not have access to or insights into the environment of the destination provider of data processing services.

Instead, the source provider of data processing services should take all reasonable measures within its power to facilitate the process of achieving functional equivalence through the provision of capabilities, adequate information, documentation, technical support and, where appropriate, the necessary tools.

Data processing services which concern services of which the majority of main features has been custom-built to respond to the specific demands of an individual customer or where all components have been developed for the purposes of an individual customer should be exempted from some of the obligations applicable to data processing service switching. This should not include services which the provider of data processing services offers at a broad commercial scale via its service catalogue. It is among the obligations of the provider of data processing services to duly inform prospective customers of such services, prior to the conclusion of a contract, of the obligations laid down in this Regulation that do not apply to the relevant services. Nothing prevents the provider of data processing services from eventually deploying such services at scale, in which case that provider would have to comply with all obligations for switching laid down in this Regulation.
