This article is part of an A to Z series by Cloud and SaaS Awards, continuing with H for Hybrid Cloud 

Cloud computing, a novel computing paradigm that offers adaptable and on-demand infrastructures, platforms, and applications as services, has drawn a lot of interest in recent years. As the name implies, cloud computing is a technology that allows for the virtualization of software administration and information sharing. Virtual technology is utilized, just as in other programming languages, to reduce storage space and speed up operations. Users can use computer technology without installing it on their machines thanks to cloud computing.

Cloud computing boosts computing efficiency by centralizing data processing, bandwidth, and storage. The virtualization of the host server, or the primary controlling computer, is the main emphasis of this technology. This server works as a communication network where data can be exchanged. Through an extensive worldwide platform, the data can be saved, accessed, and shared as needed.

The hybrid cloud is understood as a mixed environment of storage, computing and services made up of on-premises infrastructure, private cloud services and a public cloud, such as Amazon Web Services (AWS) or Microsoft Azure, with orchestration between the various platforms.

The evolution of cloud computing

The Information Technology (IT) sector has deep and extensive roots, and these roots are where the evolution of cloud computing began in the 1980s.

Users can link their PCs to other computers and servers to share information and documents and to use remote applications thanks to the development of network and internet technologies in the 1990s. However, a standard server or key was still not developing for information sharing on a global scale.

In the early 2000s, users could access a number of external and shared computer resources through an electronic grid, through an Ethernet or the Internet cable, thanks to new technologies like Web 2.0 and distributed computing. The term “cloud computing” refers to an IT service paradigm that enables the self-service delivery of a variety of practical, on-demand, and customisable computing services and resources to clients over a network, regardless of device or location.

The hybrid cloud computing

Both private and public clouds are effective and adequate in their respective domains, but larger-scale development processes and sharing agendas call for more focused and widely accessible information and data exchange. A hybrid cloud computing model focuses on combining or hybridizing private and public clouds to make clouds more noticeable and effective.

The hybrid approach is essentially a private cloud that enables an enterprise to use a public cloud as and when needed for information sharing. This architecture offers a more effective way to safeguard data and applications.

Nonetheless, a hybrid cloud architecture can offer a higher level of security for sensitive data and situations where businesses are subject to industry and financial rules. In the business-oriented sectors, this technique and model are the most utilitarian. Based on their unique fluctuations in actual consumption, businesses can modify the amount of processing power they utilize thanks to the cloud model.

Therefore, a hybrid architecture helps businesses with a wide range of computing needs, considerably more efficient by accessing a public cloud when more processing power is required. In general, expanding a company’s private cloud to accommodate growing demand is a far more difficult prospect than adding public space to its cloud architecture.

As a result, a hybrid is more cost-effective than a private cloud at offering top-tier computing capacity that is accessible whenever and wherever it is needed. The hybrid cloud can be fixed in a number of ways. This includes choosing the necessary cloud-connected applications and other services, as well as information exchange and redistribution.

Security issues with hybrid cloud

The amount of data kept in the cloud is growing along with its use, making information security, privacy, and authentication crucial. Data storage and transfer to many platforms and users is a delicate and time-consuming process. In the event that data leaks, the consequences could be disastrous.
Consequently, a few approaches or tactics for stopping data loss and leaks are provided below with data security as the primary goal.

  • Data Handling Mechanism: classified information is private; the data’s geographic location is identified; procedures for data erasure are established.
  • Data Security Migration: encrypted personal information; avoiding sensitive data in the cloud.
  • Standardization: norms should be upheld while handling and tracking data.
  • Accountability: data loss or privacy violations in the workplace could be dangerous.; every stage needs to be audited in order to increase trust.

The future of the hybrid cloud

A corporation may use a multicloud in addition to the pure private, pure public, and hybrid situations. This means employing multiple clouds for different services, such as running applications in both AWS and Azure. Some people limit the definition of “multicloud” to include only public cloud providers, while others only include hybrid clouds. Cloud service providers may eventually use the Intercloud, which means they will rely on one another for resources and services in a similar fashion to how airlines code-share, federate into alliances like the Star Alliance, or rebook passengers from canceled or overbooked flights.

A multicloud or single public cloud environment is most likely for small organizations, including startups, whereas a hybrid cloud future seems more likely for large enterprises. The relative unit costs of resources, performance variances, consumption trends, and utilization uncertainty all play a major role in a quantitative total cost analysis.

Even when the unit cost of public cloud services and resources is higher than that of private dedicated resources, as some decently sized, well-run IT firms can and have done, hybrid clouds can still provide economic benefits. These advantages materialize, in other words, for many, if not most, real-world computing workloads, when there is fluctuating demand. However, other costs that must be taken into account include those for managing hybrid clouds, data transfer, and development complexity.

Instead of just being a disorganized collection of disparate clouds and uses, a real hybrid cloud should be a seamless combination of private and public clouds. Private and public clouds might be better referred to as fixed cost and usage-based-cost clouds, respectively, for economic analysis. Cloud computing and storage are often referred to as private, public, and hybrid clouds. They are found in a wide range of industrial sectors, including capital, real estate, and transportation.

Workloads must be able to move from private to public, public to private, or run in both environments simultaneously to be considered a true, seamless hybrid cloud.
