Hybrid Cloud – Everything you need to Know

Cloud Computing is popular because of its various Models. So today, we will discuss the Hybrid Cloud Model, one of the most popular and industry favorite Cloud models. So, let us begin the Journey.

What is a Hybrid cloud?

A hybrid cloud is a popular cloud model which connects a minimum of one public cloud and one private cloud. It has orchestration, management, and application portability features to make one flexible, optimal cloud environment for running a company’s computing workloads.

Hybrid multi-cloud may be a hybrid cloud infrastructure with quite one public cloud from one cloud service provider.

Hybrid cloud helps combine best-of-breed cloud services and functionality from multiple cloud computing vendors available in the market.

It helps the organization in selecting the optimal cloud computing environment for every workload. Organizations have an ease to transfer their workloads freely between public and personal cloud as circumstances change.

Hybrid cloud, also known as hybrid multi-cloud, helps a corporation achieve its technical and business objectives more effectively and cost-efficiently than public or private cloud alone.

What is a Hybrid Cloud model?

Hybrid Cloud is a combination of two popular cloud models known as Public Cloud and Private Cloud.

In IT infrastructure, Hybrid Cloud connects a minimum of one public cloud and at least one private Cloud. It provides a greater flexibility rate to businesses by transporting workloads between cloud solutions as per the requirements and depending on that, the billing fluctuates.

The hybrid cloud model is powerful as it assures and provides businesses with substantial control over their private data. The main aim of Hybrid Cloud is to combine Public and Private Cloud to create a link-up, automated, and well-managed computing environment.

In Hybrid Cloud, the Public Cloud plays the role of performing non-critical activities. On the other side, the Private Cloud plays a part in performing critical activities.

For example, a company can store sensitive data like contact details on the private Cloud and grip the massive computing resources on the Public Cloud.

A hybrid Cloud depends upon a single management pane, not like a multi-cloud strategy where it is the admin’s responsibility to manage each cloud environment individually.

Hybrid Cloud is mainly used by industries like healthcare, finance, and universities. The leading hybrid cloud providers in today’s market are Amazon, Microsoft, Google, Cisco, and NetApp.

Hybrid Cloud Architecture

Hybrid Cloud Architecture

Consistent management of Public and Private cloud resources is ideally preferred to companies to manage Cloud environments. It helps in reducing the process of redundancies.

But separately managed cloud environments increase the possibility of security fault if every solution is not entirely optimized to efficiently work with other users.

Hybrid Cloud Architecture practice helps users reduce security risks by reducing the exposure of personal or private data on the public Cloud. Hybrid Cloud includes Public Infrastructure as a Service (IaaS) platform and a private cloud for accessing the data in a secure network.

Many Hybrid cloud models use Local Area Networks (LANs) and Wide Area Networks (WANs).

The initial step of adopting cloud technology is the IaaS solution and expanding the Private Cloud functionalities. For deploying Hybrid Cloud effectively, the public Cloud and private Cloud must be agreeable or compatible with each other for communicating.

In many scenarios, the private Cloud is built to be compatible with Public Cloud.

IaaS providers like Amazon, Google, and Microsoft made business more accessible for companies to connect with their local services to public cloud solutions. Application Programming Interface (API) helps users to improve the interaction between services. Hybrid Architects launch a hypervisor layer for generating virtual machines that connect the public Cloud with another additional software layer.
This software layer is responsible for balancing among cloud environments.

How do hybrid clouds work?

A hybrid cloud model allows enterprises to deploy workloads privately in IT environments or public clouds and move between them as computing needs and costs change. It offers a wide range of flexibility and more data deployment options. A hybrid cloud workload also includes the following.

  • Network
  • Hosting
  • Web service features of an application.

How is Hybrid Cloud managed?

Management of Hybrid Cloud is a difficult task, but every cloud provider has its own API, storage, management rules, network capabilities, and many more solutions. By winning over these solution challenges are possible, but it is not suitable.

Thus, the professional cloud employees are completely responsible for managing hybrid Cloud and constructing a single interface to smoothly manage all cloud services.

Developing such an interface requires an expertise team familiar with cloud solutions handlings. And acquiring different networks for smooth and effective communication.

Luckily enterprise-grade management tools are available in the market to help IT managers get their systems up and running.

Hybrid Cloud Providers

Below is the list of renowned Hybrid Cloud Providers, and they are as follows:

  • Amazon Web Services (AWS)
  • Google Cloud Platform (GCP)
  • Microsoft Azure

What are the types of environments found in hybrid clouds?

1. Public cloud

A public cloud might be a cloud service traveled by an external vendor, including servers in one or multiple data centers. Various organizations share public clouds. With virtual machines, individual servers could also be shared by different companies, a situation called “multitenancy” because multiple companies are renting server space within an equivalent physical server.

2. On-premises private cloud

It is a personal cloud or a data center wholly owned by a single organization. The servers during a private cloud are not shared by any second party software, files, or data. On-premises private clouds are maintained and secured by the organizations and not by any external vendor.

3. Hosted private cloud

This is often a bit like an on-premises private cloud where the servers are dedicated wholly to at least one organization. However, the cloud servers during a hosted private cloud do not reside in an organization’s offices. Instead, a third-party provider takes responsibility for hosting and maintaining the cloud servers in one or more remote data centers. Therefore, the organization accesses the cloud over the web rather than an indoor network. But unlike a public cloud, there’s no multitenancy; the cloud servers aren’t shared with other organizations.

4. On-premises (legacy)

On-premises or legacy deployments do not adopt cloud technology in the least. Instead, organizations using the following model follow the traditional practice method of purchasing software licenses, installing and maintaining hardware on their premises, and installing software locally on employee computers.

How do the different environments communicate with each other in a hybrid cloud?

In a hybrid cloud also, the connection between the different clouds is vital. Public clouds, private clouds, and on-premises infrastructure can hook up with one another during a sort of ways which includes the following:

  • APIs (Application Programming Interfaces)
  • VPNs (Virtual Private Networks)
  • WANs (Wide Area Networks)

Without working connections between clouds, the organization is not running a hybrid cloud. They are simply running two or more separate cloud environments in parallel, and that they will not experience the advantages of hybrid cloud deployments.

Is Hybrid Cloud the Right Choice?

Everything is not available in Public Cloud, and it is a vital reason companies are looking forward to adopting a hybrid mixture of cloud services. Thus, Hybrid Cloud helps companies gain benefits of both Public and Private Clouds and benefit an existing architecture.

The Hybrid approach permits applications and components to communicate between cloud instances and architectures, like traditional Vs. Modern architecture.

For Data equivalent amount of distribution and access flexibility is also required. Whether in handling workloads or datasets, planning is very essential to perform all operations. The characteristic of Hybrid cloud Architecture are as follows:

Users on-premises data centers, public and private cloud resources, and workloads are grouped together under one standard roof to manage data while staying recognizable.

Users can connect their existing and running systems available on Traditional architecture, which helps run business-critical applications. Or it holds sensitive and critical data that might not be suitable for the public Cloud.

The infrastructure of Hybrid Cloud is connected with Data Fabric. It uses a software-defined approach for providing a standard set of data services across the combination of IT resources.

Hybrid Cloud Scenarios

Hybrid Cloud Scenarios

Many users or enterprises use Hybrid Cloud in the following scenarios:

1. Dynamic or Frequent workloads changings

It uses an accessible scalable public cloud for active and frequent workloads. Except for low volatile or sensitive workloads in a Private Cloud or in the on-premises cloud data center.

2. Separating or distinguishing critical workloads from less sensitive workloads

Users might store sensitive information related to the health, finance sector on the Private Cloud. And users can use Public Cloud for running and deploying other enterprise applications.

3. Big Data Processing

It is doubtful to process extensive data operations continuously at a continuous volume set. Instead, users can perform some big data analytics by using highly scalable resources of the public Cloud. Also, the user can use the Private Cloud to ensure data security and keep sensitive and crucial data behind the firewall.

4. Moving to the Cloud is additional at users’ own space

Users can place some of their workloads on public Cloud or a small amount in a private cloud. It depends on the enterprise to continue the expansion of cloud existence as per requirements. It can be either Public Cloud, Private Cloud, or Hybrid Cloud.

5. Short Term Processing Capacity Requirements

A Hybrid Cloud authorized users to assign the public Cloud resources for small projects at a lower cost than using their own data center. By following this method, users will not invest a heavy amount in the equipment as it is only temporarily required.

6. Flexibility for Future

No matter how well the user or a company runs an infrastructure to fulfill today’s requirements. But there will be changes in the future requirements. Adopting hybrid cloud companies will complement or match the data management requirements inside the public or private Cloud. It depends upon the best scenario to manage.

7. Best of Both Worlds

By opting for Hybrid Cloud, users can get advantages of both Cloud models.

Hybrid Cloud Use Cases

Hybrid Cloud Use Cases

1. Digital transformation

Organizations are openly working on modernizing their traditional IT infrastructure by adopting the Public Cloud model. Some legacy issues and compliance factors might prevent the organizations from shutting down their running data centers completely.

The hybrid cloud model permits organizations to migrate their IT infrastructure on cloud premises with a combination of data set and application sets. Some of their on-premises applications reside in their owned data center.

2. Disaster recovery

By moving to a hybrid cloud, organizations are relaxed on securing their disaster recovery strategy. They create copies of their on-premises workloads and backup their data on the cloud. If they face any challenge, the data center workloads fail in the cloud environment and can operate precisely with on-demand cloud resources. But the implementations must be managed decently to avoid hybrid cloud backup challenges.

3. Development and testing.

The development and testing cost in the public cloud is cheaper, and the team can develop it faster. The key reason is that the organization does not require buying and managing the on-premises physical hardware resources.

4. Data processing.

Hybrid Cloud helps organizations utilize the complete services of the public cloud for analytical queries for locally stored data.

5. Highly changeable workloads.

Hybrid Cloud is famous for its dynamic workloads. Let us consider the transactional order-entry system, which faces rotational demand hikes, and it is an excellent hybrid cloud applicant.

6. Exploration of the cloud provider

Organizations make use of a hybrid cloud to evaluate a possible public cloud migration. IT teams of the organization can experiment and play with the cloud skills on a small scale, and they can learn to work with the Cloud vendor before moving on to complete adoption of the Public Cloud.

Benefits of Hybrid Cloud

Benefits of Hybrid Cloud

1. Flexible and secure

As there is the availability of Public Cloud, Hybrid Cloud provides flexibility to users. And the resources are secure with the help of the Private Cloud.

2. Cost-Effective

A hybrid cloud is less expensive compared to a private Cloud. It helps organizations to reduce costs for infrastructure and applications. Users enjoy both the features of the Public and Private Cloud. It is capable of adapting demands as per the user or company’s requirements.

3. Security

Users get security in Hybrid Cloud as all the critical activities are performed inside the Private Cloud.

4. Risk Management

Enterprises can manage the task operations easily and fantastically with the help of Hybrid Cloud.

5. Agility and Scalability

Hybrid Cloud offers more resources and services with the help of Public and Private Cloud than traditional on-premises architecture. And this factor makes it easier for users to deploy and scale resources according to the requirements.

When the demand rises with a spike, the users can trust Public Cloud for accessing additional scalability and capacity.

6. Resiliency and Interoperability

To run the business smoothly, users can run their services constantly on both the Public and Private Cloud. Also components of one workload or service are capable of running in both environments.

7. Compliance

In Hybrid Cloud, organizations can reside their data in a private location. And can operate workloads in the Cloud. Secondly, users can manage their workloads in a private on-premise data center and play with data to and from the Public Cloud as per the requirements.

This factor helps users to meet their everyday needs along with the elasticity feature from Cloud.

Risks of Hybrid Cloud

Risks of Hybrid Cloud

1. Network Issues

Networking is a complex issue in Hybrid Cloud. Because it is a combination of both Public and Private clouds.

2. Infrastructure Compatibility

Users face Compatibility problems in Hybrid Cloud. The Private Cloud is responsible for company controls as there are dual infrastructure levels, whereas the Public Cloud is not. So there is a possibility that they are running individual stacks.

3. Reliability

Users entirely depend on the Cloud Service Provider on the Reliability factor.

4. Data handling

Organizations can face some issues while transferring and moving the data to the Hybrid cloud. Also, sometimes it might create security issues and price challenges. So they should ensure that the workload resides publicly in the cloud storage to avoid unnecessary transfers and high bills.

5. Complex access management

In Hybrid Cloud, Authentication and authorization are the critical security issues. Organizations move towards centralized protocols for accessing the data in public and private cloud environments. Using tools like IAM and SSO tools can assign permissions only to the users who are authorized to utilize Hybrid Cloud.

6. Skills gap

If the organizations adopt a Hybrid Cloud, they should ensure that their staff has the skill set. An expert team is required to figure out the difference between public cloud and personal cloud.

7. Private cloud maintenance.

Every Cloud Model located on-premises or remotely requires enormous investment, maintenance, and expert team. Implementing extra software such as helpdesk systems, databases, chatbots, etc., can confuse a private cloud. Correct data planning, public security tools, and investing in employee training and cloud certifications help resolve multiple challenges while adopting Hybrid Cloud.

Who uses Hybrid Cloud?

Businesses across industries have moved toward hybrid solutions to scale back costs and strain on local resources. If we begin the discussion from the financial sector to the health care industry, hybrid cloud environments have proved their effectiveness at improving computing and storage power, also successfully optimizing the scarce resource of physical space. Many organizations do not have the space available to deploy servers on-site.

Data privacy is the crucial element in the healthcare industry, and privately held computation resources are somewhere lacking. So in this scenario, the hybrid cloud model is a perfect solution because it allows medical field organizations to get the patient’s data because of having a safe and private server. Also Hybrid Cloud model helps in leveraging the advanced computational power of a public IaaS model.

What is the difference between hybrid cloud and multi-cloud?

A multi-cloud deployment combines multiple public clouds, while a hybrid cloud combines a public cloud with another sort of environment.

A multi-cloud also can be a hybrid cloud if it mixes multiple cloud environments and uses various public clouds, even as a rectangle is often a square, but not all rectangles are squares. Conversely, a hybrid cloud deployment also can be multi-cloud if it uses several public clouds.

Public Cloud vs Private Cloud vs Hybrid Cloud

Cloud Deployment Models Public Cloud Private Cloud Hybrid Cloud
Cloud Environment In Public Cloud there is a Multi-Tenancy shared environment for the users. In Private Cloud there is Single Tenancy. It is only for the single purpose of an organization. In Hybrid Cloud the users have both Cloud Environments available (Single tenancy and multi tenancy.) When the data is kept in the public cloud it will offer a multi-tenant environment. It means the data from various organizations are stored in a shared environment. Alternatively, in Private cloud the data is stored privately which can be used by a single organization.
Data Center Location The data center can be located at any location where the services of cloud vendors are available. The data center is available inside the infrastructure of an organization. For Private cloud users the data center is available inside the organization’s infrastructure. And in Public Cloud it is at any location where the cloud provider services are available.
Resource Sharing Hardware, network and storage resources are shared by many users in the cloud. In a private cloud there is no sharing of resources. It is always dedicated to a single organization. In Hybrid Cloud Resource sharing is very secure and with integration solutions there is an additional level of security.
Storage Public Cloud offers storage as a service. The billing is generated on a pay-as-you-go model. It is the best solution for backup for disaster recovery planning. Private Cloud offers internal cloud storage which runs on a specific infrastructure in the data center of an organization. Hybrid Cloud manages the storage which uses both local and off side resources as a gateway between the on-premises cloud storage and public cloud storage.
Scalability In Public Cloud the scalability is immediate and unlimited. There is an issue on scalability but private cloud offers considerable control and security. In Hybrid Cloud the scalability is on demand at unlimited resources.
Pricing or Billing The billing is generated depending on the usage. In Private cloud the pricing is very expensive. The pricing is high but it offers many advantages.
Cloud Security The security feature in Public cloud is decent but it depends on the security measures offered by the cloud vendor. Private Cloud is most secure compared to Public and Hybrid cloud models. Hybrid Cloud is secure.
Performance The performance in Public Cloud ranges from Low to Medium. In Private Cloud the performance rate is very high. The performance rate of Hybrid Cloud is very high.
