Cloud Interoperability And Portability – A Simple Overview(2021)

Ajay Ohri


Numerous businesses are presently utilizing at least 4 particular IT conditions, including the cloud. Yet, the cloud is certainly not a solitary, independent item; it’s a mind-boggling arrangement of administrations worked in-house or conveyed by various, frequently contending suppliers. Cloud purchasers that need to keep away from seller lock-in search for include rich administrations joined with a vigorous climate that underpins multi-merchant alliance, completely incorporated security and solidified administration. 

As cloud services become more critical to organizations today, Cloud Interoperability and Portability become something beyond multisyllabic IT terms.

1) Definition

Similarly, as with most IT ideas, alternate points of view lead to various definitions, particularly when solidification around a specific definition may offer a serious edge. The accompanying definitions, in light of ISO/IEC19941, are the result of long discussions among industry specialists.

Interoperability: Interoperability is the capacity of at least two applications or systems to trade data and to utilize the data that has been traded commonly. Cloud interoperability is the capacity of a client’s framework to interface with a cloud service or the capacity for one cloud service to connect with other cloud benefits by trading data as per an endorsed strategy to get unsurprising outcomes. 

The two important elements of Cloud interoperability are usability and connectivity and have been separated into 5 layers:

  1. Behaviour
  2. Policy
  3. Semantic
  4. Syntactic
  5. Transport

Portability: Portability, then again, is moving the applications or data starting with one framework then onto the next and having it stay executable or useable. Portability can be broken into two kinds: Cloud data portability and Cloud application portability.

  1. Cloud data portability: It is the capacity to effectively move information starting with one cloud service then onto the next without expecting to re-emerge the information.
  2. Cloud application portability: It is the capacity to move an application starting with one cloud service then onto the next or between a client’s current circumstance and a cloud service.

2) Cloud portability and interoperability categories to consider are:

  1. Publication and Acquisition Interoperability
  2. Management Interoperability
  3. Platform Interoperability
  4. Application Interoperability
  5. Platform Portability
  6. Application Portability
  7. Data Portability

3) Problems & Solutions

The principle challenge organizations going for cloud interoperability issues is the sheer assortment of cloud APIs and interfaces, as per the Cloud Standards Customer Council paper. They aren’t normalized, and cloud service organizations utilize various ones.

Cloud infrastructure administrations have a more elevated level of cloud interoperability because their administrations are practically identical, and there are some standard interfaces. 

Developer driven stage as administration contributions is less interoperable because a couple of interface guidelines exist. SaaS application, with significantly less standard APIs, “presents the best interoperability challenge today,” the Cloud Standards Customer Council paper proceeded.

As a solution/answer to these issues, organizations can assemble a “Mapping Layer” between their own frameworks’ cloud services’ Application Programming Interface and Application Programming Interface utilizing an enterprise service bus or on the other hand, they can utilize a cloud service dealer, “which does that mapping for you.” 

The greatest difficulties disrupting the general flow of utilization movability are for Platform-as-a-Service built applications. That is because Platform-as-a-Service stages generally fluctuate; for instance, how one stage oversees information may not be upheld at all in another. The cloud interoperability challenges in every one of the cloud services classes SaaS, PaaS and IaaS will be unique.

Organizations attempting to move data starting with one cloud infrastructure then onto the next are in an ideal situation since guidelines that take into account moving applications do exist. Standard OS, for example, Linux, can help to move data. An open-source stage, for example, Cloud Foundry, can help to migrate data among Platform-as-a-Service frameworks and container innovation; for example, Docker can help move bits of applications.

A few standards organizations have been striving to explain, qualify and define the elements of cloud interoperability and standards & cloud portability and standards. The objective is a more open cloud computing that limits the risk of merchant hindrances and maintains a strategic distance from the shortcomings of contradictory administrations.

Several Standards Organizations are:

  1. The European Telecommunications Standards Institute.
  2. The National Institute of Standards and Technology.
  3. The Institute of Electrical and Electronics Engineers.
  4. The International Organization for Standardization.
  5. International Telecommunications Union – Telecommunications Sector.
  6. Cloud Standards Customer Council.


Cloud computing interoperability diminishes specialized intricacy by dispensing with custom interfaces, converters and gateways. Cloud computing portability is regularly referred to as being required generally to relieve merchant lock-in. Be that as it may, moving to start with one framework then onto the next with at least exertion, as might be conceivable with container services, can likewise improve scalability and resilience.

Eventually, greater adaptability to change service providers, having fewer hindrances to the influence of best of breed arrangements, and more prominent capacity to arrange lower costs, and better assistance quality are clear advantages for the cloud client. Quick advancement in industry guidelines will energize the improvement of cloud interoperability.
