In a bid to match ever-changing business requirements, most organizations now use some combination of the public cloud, on-premise computing, and private clouds in a data centre. This combination is called a hybrid cloud. As per a study, the global hybrid cloud market size is expected to reach $171,926 million by 2025 with a CAGR of 21.7% from 2018.
What is a Hybrid Cloud and why is it gaining popularity?
A hybrid cloud is an integrated cloud service. It combines private and public clouds and provides versatility, large storage spaces and reduces capital expenditure. Data can be connected on public and non-public cloud either via the public internet or over a private network with VPN, WAN or APIs. These systems are managed by an overarching tool that eliminates the need to manage each cloud separately.

You can build a hybrid cloud for your organisation with the same operating system by developing and deploying apps as collections of small, independent and loosely coupled services that would be managed via a unified platform.
Enterprises globally need to adapt and change direction quickly. You do not need to redesign or modify applications and can easily lift and shift them from private to public cloud or vice-versa. Most technology management organizations have two agendas: the IT agenda and the business transformation agenda. Hybrid clouds can save money, provide agility and propagate both the IT and business transformation agendas.
Transforming Businesses With Hybrid Cloud
A hybrid cloud can offer organisations the freedom to use a private cloud in an on-premise setup to host sensitive or critical workload. It allows for a smooth transition of workloads between public and private cloud environments with minimal computing resources.
Hybrid cloud lets an enterprise share the responsibility of delivering and managing applications with its service provider. The consistency of the application services and standardized security norms throughout a hybrid environment ensure that the application resources are available throughout enterprise platforms and networks. This is beneficial for companies deploying Software as a service (SaaS) applications.
A hybrid cloud strategy:
- Allows businesses to decide the specifications of dedicated servers as well as network devices.
- Provides a higher level of control over big data analytics and lets you serve your customers better. For example, your retail-order entry application can be run on the private cloud during normal sales and on the public cloud when demand spikes.
- Streamlines computing requirements and helps in scaling and storing data on one cloud while running analytics on the other.
You can partition an application and separate workloads by running the application on the public and private cloud sides of the hybrid cloud simultaneously. For example, the transaction layer can be run on a public cloud and data and user-interface can be run on private cloud.
Reliability is king in the IT industry, and a hybrid cloud offer this crucial without any downtime. Enterprises can also ensure 24*7 data retrieval, organisation, analysis and archival with monitored defences in the hybrid cloud. You also get data security by deciding where workloads are stored and performed, thus, limiting data exposure.
Costs of Hybrid Cloud
A hybrid cloud setup is likely to come with higher initial charges, owing to initial equipment purchase costs for businesses. It is therefore not suitable for latency-sensitive applications. Shifting data between private and public clouds can create untenable latency. Moreover, server costs for small applications are higher. However, adopting a hybrid cloud allows businesses to match their actual data management requirements to the public cloud, private cloud or on-premise resources that are best able to handle them.
Should You Adopt Hybrid Cloud?
The opportunities here lie in optimizing services such as Internet-as-a-Service, Platform-as-a-Service and Software-as-a-Service along with your apps, data and infrastructure. A hybrid cloud can potentially transform the digital landscape of your organisation. The most important step in realising its benefits are analyzing the applications in terms of function, architecture, technology and its configuration.
