The distributed cloud is a brand-new strategy that allows businesses to manage all disparate components as one coherent cloud, including edge apps, apps that span several clouds, old datacenter initiatives, and the infrastructure to support them all.

Having able to manage, run, and protect all of these compute regions as a single, distributed cloud is the Ultimate Aim. This entails installing apps with a standard set of policies and a centralized view of all locations and infrastructure.

Distributed cloud is defined as the distribution of public cloud to various physical locations,  whilst original cloud service is responsible for the governance, updates, operation, and evolution of services.

Organizations may minimize latency, the risk of data loss, and network congestion,  by using a distributed cloud architecture. Furthermore, since data may be stored in the nation where it was produced, businesses can better guarantee compliance with data sovereignty laws.

On the surface, the market’s public clouds already meet the concept of a distributed cloud. The majority of big cloud service providers, such as  Google Cloud Platform, Microsoft Azure, Amazon Web Services (AWS) and Oracle Gen2 Cloud, have a worldwide presence with data centers and points of presence spread throughout the globe (PoPs).

They all have edge devices or what are known as PoPs edge locations. Because these big cloud providers operate their services mainly in centralized data centers rather than network edge devices.

What is the functionality of a distributed cloud?

To minimize latency, services in a distributed cloud are placed or “distributed” to particular locations, and these services have a single, uniform control point across public and private cloud environments. According to Gartner, organizations can see significant performance progress by lowering latency and reducing the overall risk of outage or control plane inefficiencies

A distributed cloud transmits not just an app, but the whole computing stack to the places where it is required, either on-premises, in a third-party colocation facility, or in a public cloud provider. The cloud provider controls all of the components of the distributed cloud as a whole from a single control plane, as well as the consuming cloud client perceives this distributed infrastructure as a single cloud entity.

Security, availability, upgrades, and governance of the whole distributed infrastructure remain the responsibility of the public cloud provider. Distributed cloud, according to Gartner, “fixes” what hybrid cloud and multi-cloud fail to do.

Distributed Cloud Infrastructure vs. Current Cloud Infrastructure

According to  “Top 10 Strategic Technology Trends for 2020,  by Gartner’s new cloud model, a distributed cloud is distinct from the cloud infrastructures that are presently in use. A distributed cloud, focuses on extending cloud services to edge devices and client data centers. All of the services accessible at a central cloud data center at the edge are available in the new architecture.

The report does admit, however, that certain edge devices may not yet be capable of this.

Another edge element influencing the spread of public cloud services will be the capabilities of edge, near-edge, and far-edge platforms that may not require or cannot operate a like-for-like service that replicates what is available in the centralized cloud,” it adds.

It is noteworthy that the statement discusses many types of edge. Fog computing refers to the spectrum of near- to far-edge computing. Fog computing devices are located outside of the core network but not yet at the network’s furthest edge. These devices run cloud services in the same way as dispersed clouds do.

The second distinguishing feature of a distributed cloud is what the cloud provider must accomplish in order for their cloud to be classified as a distributed cloud.

According to the study, “at a minimum, the cloud provider must develop, construct, distribute, maintain, and upgrade these services if they are to be regarded as part of the dispersed cloud spectrum.”

How to Run a Distributed Cloud

The cloud provider takes responsibility for the distributed cloud’s operation, governance, maintenance, and upgrades. Despite this, the study admits that this is unfeasible.

As this kind of cloud becomes more widely used, the business models are comparable to the presently prevalent software, infrastructure, and platform-as-a-service approaches.

A client buys and owns a hardware platform and software layer with a subset of the providers’ cloud services in a software business model. The client is then in control of the software and hardware’s operations, maintenance, and upgrades. A managed service provider may help a client with their obligations.

The client is responsible for the hardware platform, while the service provider is liable for the software overlay, under a portability layer business model.

A provider providing a version of cloud services in a hardware and software combination is referred to as a distributed service business model. The hardware and software would be managed and updated by the supplier. The distributed service method is essentially the same as a software-as-a-service (SaaS) alternative.

Fog and Edge Computing’s Role

Fog computing and edge computing are used in the infrastructure of a distributed cloud. Despite the fact that the titles of these two technologies indicate that they concentrate on computing resources, their deployments nevertheless include storage and networking resources.

Fog computing may help decentralized data centers improve latency and decrease network congestion. Edge computing is similar in that most of the storage and workloads required by an end user are performed as close to the user as feasible. However, traffic that the two technologies can’t manage will be sent to a cloud data center — dispersed or centralized — with greater power or space.

On the Horizon

As edge computing and decentralization become more prevalent, distributed cloud usage will certainly continue to rise. Edge computing will become more important as new use cases emerge, such as the Internet of Things (IoT) , in which a device’s demanding tasks are sent to the cloud. Cloud services will decentralize as edge computing becomes increasingly prevalent.

SD-branch and Secure Access Service Edge (SASE) networking methods are also decentralizing network management and equipment to distant areas inside companies. Cloud networking is a term used to describe this procedure.

What to Look Forward to in the Future

As edge computing and decentralization get more prevalent, distributed cloud will continue to gain traction. Edge computing will become more important as new use cases emerge, like the Internet of Things (IoT), in which a device’s demanding tasks are sent to the cloud.

Takeaways from the Distributed Cloud

Major cloud providers already have dispersed cloud architecture in place.

What today’s cloud providers lack is the ability to operate services at the network edge utilizing edge devices.

Cloud services may now be run anywhere between the central data center and the extreme network edge thanks to fog computing.
