Cloud computing has become the best security service in IT infrastructure services. When computing and processing demand increases beyond an on-premises data center’s capabilities, businesses can use the hybrid cloud to scale up capacity instantly or down to handle excess capacity. Hybrid cloud plays a vital role and allows them to avoid the time and cost of purchasing, installing, and maintaining new servers they may not always need. The hybrid cloud has boosted the flexibility of private firms and is well known for its quality services.
It combines public cloud services, private cloud services, and on-premises infrastructure and provides orchestration, management, and application portability across all three. Hybrid cloud management results in a unified, flexible, distributed computing environment where an organization can run and scale its traditional or cloud-native workloads on the most appropriate computing model.
A hybrid multi-cloud is a cloud that includes public cloud services from more than one cloud service provider. It enables a company to
- Integrate best-of-breed cloud services and functionality from multiple cloud computing vendors
- Choose the optimal cloud computing environment for each workload, and
- Remove tension and move workloads freely between public and private clouds as circumstances change.
Hybrid cloud, particularly hybrid multi-cloud, helps a company achieve its technical and business objectives more effectively and cost-efficiently than public or private clouds alone. In fact, according to one recent study, companies derive up to 2.5x the value from a hybrid cloud than from a single-cloud or single-vendor approach.
How Does Hybrid Cloud Work?
There are mainly two types of architecture that the hybrid cloud follows for its working, which are known as Traditional Hybrid Cloud Architecture and Modern Hybrid Cloud Architecture:
Traditional Hybrid Cloud Architecture
Initially, hybrid cloud management architecture focuses on transforming portions of a company’s on-premises data center into private cloud infrastructure and then connecting that infrastructure to public cloud environments hosted off-premises by a public cloud provider.
This is accomplished using a prepackaged hybrid cloud solution or enterprise middleware to integrate cloud resources across the environments, and unified management tools for monitoring, allocating and managing those resources from a central console or ‘single pane of glass.

The result of traditional hybrid architecture was a unified IT infrastructure well-suited to several use cases:
- Security & Regulatory Compliance: Reserve behind-the-firewall private cloud resources for sensitive data and use more economical public cloud resources for less-sensitive workloads and data.
- Scalability & Resilience: Cloud bursting is used for public cloud computing and cloud storage resources to scale up quickly, automatically, and inexpensively in response to unplanned spikes in traffic without impacting private cloud workloads.
- The Rapid Adoption of New Technology: Adopt or switch to the latest software-as-a-service (SaaS) solution, and even integrate those solutions into existing applications without equipping new on-premises infrastructure.
- Enhancing Legacy Applications: Use public cloud services to enhance existing apps’ user experience or extend them to new devices.
- VMware Migration: ‘Lift and shift’ existing on-premises workloads to virtualized public cloud services to reduce the on-premises data center footprint and scale as needed without additional capital equipment investment.
- Resource Optimization & Cost Saving: Running workloads with predictable capacity on the private cloud and migrating more variable workloads to the public cloud; using public cloud infrastructure to quickly ‘spin up’ development and test resources as needed.
Modern Hybrid Cloud Architecture
Modern hybrid cloud architecture focuses less on physical connectivity and more on supporting the portability of workloads across all cloud environments and on automating the deployment of those workloads to the best cloud environment for an allocated business purpose.
As part of the next critical step in digital transformations, organizations are building new applications and modernizing legacy applications to leverage cloud-native technologies – technologies that enable consistent and reliable development, deployment, and performance across cloud environments and vendors.
Specifically, the primary focus is on building or transforming applications to use microservices architecture, which breaks applications into smaller, loosely coupled, reusable components focused on specific business functions. And the Modern Hybrid Architecture is deploying these applications in containers – lightweight executable units that contain only the application code and the virtualized operating system dependencies required to run it.
At a higher level, public and private clouds are no longer in urge for physical ‘locations’ to connect. Many cloud vendors now offer public cloud services that run in their customer’s on-premises data centers; private clouds, once run exclusively on-premises, are often hosted in off-premises data centers, on virtual private networks (VPNs) or dedicated infrastructure rented from third-party providers.
What’s more, IT infrastructure services virtualization, also called infrastructure as code, lets developers create these environments on demand using any compute resources or cloud resources located behind or beyond the firewall. This adds importance with the advent of edge computing, which offers opportunities to improve global application performance by moving workloads and data closer to where the actual computing gets done.
As an outcome of these and other factors, modern hybrid cloud infrastructure is starting to coalesce around a unified hybrid multi-cloud platform that includes:
- Supporting cloud-native application development and deployment across all cloud types (public and private) and cloud providers
- Setting a single operating system across all environments.
Cloud-native development and management let developers transform monolithic applications into units of business-focused functionality that can be run anywhere and reused within various applications. A standard operating system lets developers build any hardware dependency into any container.
Organizations that use a hybrid cloud platform can use many of the same security measures in their existing on-premises infrastructure—including security information and event management (SIEM) capabilities. Some IT infrastructure services find hybrid cloud security superior to their on-premises data center because of always-up-to-date, automated data redundancy, high availability, disaster recovery, and cybersecurity features.
