What is Hybrid Cloud Architecture Explained with Diagrams

What is Hybrid Cloud Architecture Explained with Diagrams. The abundance of the terminology used to describe cloud installations, such as hybrid cloud, multi-cloud, distributed cloud, and hyper-converged infrastructure is so vast. 

Compared to virtually any other contemporary data management phrase, hybrid cloud has been used to describe a more extensive and diverse range of IT solutions. As a result, uncertainty over the idea is understandable. 

This guide introduces the concept of hybrid cloud architecture, accompanied by diagrams for easy digestion. Then, we examine its features, benefits and challenges, types, and how it works.

Shall we start with What is Hybrid Cloud Architecture Explained with Diagrams?

What is Hybrid Cloud Architecture?

Well, through a vast area network or broadband connection, hybrid cloud architecture integrates public and private clouds, so that data and applications are shared and controlled as one IT architecture. 

All in all, it is most adapted to fluctuations in demand for computing resources because hybrid cloud infrastructure enables enterprises to scale from public cloud to on premises (private cloud) to meet decreased demand.

Whether for financial, legal, or technological reasons, many businesses process some workloads in the public cloud using infrastructure as a service (IaaS) while keeping others in their private cloud. Both,  Google Cloud Platform, Microsoft Azure, and Amazon Web Services (AWS) are the most popular public IaaS providers.

Businesses, especially mid to large companies, that frequently rely on their private cloud for legacy infrastructure and mission critical applications, are increasingly interested in hybrid cloud architecture. 

The term “hybrid” does not relate to a traditional IT architecture with cloud connectivity added. Instead, it involves the utilization of two cloud infrastructures. Furthermore, portability is crucial since task and data flexibility are essential for realizing the full advantage. This means that for a single workflow, you must be able to use both environments effortlessly.

The above requirements arose from the early days of cloud computing when location and ownership were the critical distinguishing elements between private and public clouds. However, today’s clouds are increasingly complicated, with location and ownership reduced to abstract issues.

Therefore, public cloud providers, for example, now operate cloud services on a client’s on premises data centers. On the other hand, private clouds are built on rented, vendor owned data centers that are frequently located off site.

Features of Hybrid Cloud Architecture

  • Unified Management: one overarching tool could ideally handle hybrid cloud architecture, removing the requirement for separate cloud administration. Running clouds apart is tough since each requires different APIs (Application Programming Interfaces) and SLAs (Service-Level Agreements) and has unique features and capabilities. For example, an API enables applications to “call” an element or operation from another program, such as a cloud service. A service level agreement (SLA) specifies the benefits that cloud companies supply.
  • Data Integration: synchronize your organization’s data across public and private networks. However, syncing your data across these numerous infrastructures might be difficult. As a result, you need to employ different technical solutions to keep your data consistent automatically.
  • Network Connections: A private network or the public Internet connects public clouds, private clouds, and legacy infrastructure. As a result, network connectivity is critical for hybrid cloud architecture deployment.
  • Disaster Recovery: The hybrid model helps organizations replicate their on premises workloads and back up data to the cloud. Then, in the event of a data center failure, workloads failover to the cloud environment and function, typically using on-demand cloud resources

Benefits of Hybrid Cloud Architecture

  • Flexibility: Companies work with various data types in disparate environments and adjust their infrastructure. A hybrid cloud solution combines older systems and the latest cloud technology without committing fully to a provider. Organizations move workloads between their aging infrastructure and a vendor’s public cloud when necessary.
  • Scalability and Agility: Compared to a physical data center, a hybrid cloud provides additional resource possibilities via a public cloud provider. This makes provisioning, deploying, and scaling resources to meet demand spikes easy. When demand surpasses the local data center’s capacity, a business burst the application to the public cloud to have access to other sizes and capabilities.
  • Cost management: Organizations own and handle the data center infrastructure with a private cloud, which requires significant capital expenditures and fixed costs. Alternatively, public cloud resources and services are variable and operational expenses. Hybrid cloud users run workloads in whichever environment is more cost effective.
  • Compliance: With a hybrid cloud, organizations keep data in a private environment. In contrast, managing workloads in the cloud enables the efficient transfer of data to and from the public cloud and the management of workloads in a private data center. This allows businesses to comply with legal standards while enjoying the cloud’s elasticity.
  • Reliability: A business runs workloads redundantly in private and public environments with hybrid cloud architecture. In addition, components of one workload also run in both environments and interoperate.

Hybrid Cloud Drawbacks


A hybrid cloud strategy combines on premises and public cloud environments. However, they are only partially interoperable and easily synced. For example, a hybrid cloud application’s back end data center component cannot respond as quickly as the front end public cloud component. This causes latency problems and other complexities.

Complex Access Management

Authentication and authorization are two of the leading security issues with hybrid clouds. Organizations must use centralized protocols to gain access to data in both private and public cloud environments. Focus on hybrid cloud access control by using identity and access management and single sign on tools and assign permissions only when required.

Private Cloud Maintenance

A hybrid cloud on premises or private cloud component requires substantial investment, maintenance, and expertise. Additionally, a private cloud might get more complicated by adding extra applications like databases, helpdesk systems, and other tools. However, these factors make adequate data planning, public cloud security technologies, investment in employee training and certifications, and adoption of hybrid clouds easier.

Data Handling

An improper data location and mobility in a hybrid cloud leads to cost and security issues. You encrypt all traffic for data security in transit. Also, to prevent moving data across cloud environments and triggering cloud networks, populate data in the appropriate setting. To avoid needless transfers and charge spikes, ensure that all relevant workloads are stored in public cloud storage.


Another significant challenge for hybrid cloud deployments is maintaining compliance with regulatory requirements and industry standards. Even if you use a secure cloud provider, you must ensure your organization complies with laws and regulations like GDPR, HIPAA, and PCI DSS. In addition, hybrid cloud implementations add a layer of complexity, requiring you to adopt more security measures.

Up next with What is Hybrid Cloud Architecture Explained with Diagrams we discover the types of Hybrid Cloud. 

Types of Hybrid Cloud Architecture

There are no universal hybrid solutions due to the unique nature of private clouds and the variety of services each public cloud provider offers. The traditional and modern hybrid cloud architectures, however, are the two main kinds to which every hybrid cloud belongs:

Traditional Hybrid Cloud Architecture

Traditional hybrid clouds were created by linking private cloud environments to public clouds via complicated, significant middleware iterations. Either develop your private cloud or use pre built cloud infrastructure. Of course, a public cloud provider is also required.

You must connect the two clouds, so moving resources between different settings necessitates reliable middleware. Many cloud service providers include pre configured Virtual Private Networks (VPNs) in their subscription packages.

Modern Hybrid Cloud Architecture

Organizations now create hybrid clouds in a variety of ways. For example, modern IT architects emphasize connecting the environments more than the portability of the applications that run within them. As a result, they create and implement applications as a set of separate, compact, and loosely connected services.

By managing everything using a unified platform and running the same operating system (OS) in every IT environment, the architects extend the applications’ universality to the underlying environments.

Orchestration abstracts all the application requirements while using the same OS abstracts all the hardware requirements. As a result, you create an interconnected and consistent computing environment that allows the movement of applications between environments without using APIs that change whenever you update or change cloud providers.

How Hybrid Cloud Works

We know that hybrid clouds combine in house, private, and public clouds so that data moves between different cloud environments. But how exactly does the hybrid cloud architecture operate? 

Connective tools and protocols facilitate hybrid cloud connectivity, that is, Application Programming Interfaces (APIs), Virtual Private Networks (VPNs), and Wide Area Networks (WANs). These tools connect multiple computers. 

Workloads are distributed using this foundation of interconnection. This is what enables distinct clouds to combine to form hybrid clouds. Resources are abstracted by virtual computers and software designed storage, which is gathered into data lakes. The resources are then distributed by management software to the proper environments so that they are then authenticated and deployed as needed.

Ultimately, a hybrid cloud enables on demand flexibility and offers new capabilities to legacy systems and applications. Additionally, it acts as a catalyst for digital transformation, if an organization tackles it with proper forethought and a disciplined strategy. 

The result is a flexible and responsive infrastructure that easily changes to meet shifting company needs. We anticipate that as more experts in data management become aware of the benefits of the hybrid cloud, they will use it as a critical component of their IT strategy.

What is Hybrid Cloud Architecture Explained with Diagrams Conclusion

In the end, the decision is yours: should you or your business adopt a hybrid cloud infrastructure? The 2021 State of the Cloud report from Flexera estimates that 82% of companies use a hybrid cloud strategy. This suggests that various enterprises are drawn to the advantages of the hybrid cloud.

Lastly, a hybrid cloud solution has benefits that vary depending on the demands of a company. In the early days of the cloud, it might have been acceptable to write off the hybrid cloud as little more than a trendy term, but that’s no longer the case. Instead, the hybrid cloud has advanced beyond the marketing gimmick to provide practical answers for an IT environment that is becoming more hard and complex.
