A hybrid cloud is a computing environment that combines two or more types of clouds. In most cases, private and public clouds create hybrid environments. For a cloud to be truly considered hybrid, all these different environments should be interconnected and function as one coherent infrastructure.
Hybrid cloud computing has become common because it’s very flexible. You can use a private cloud for some services and a public cloud for others. You can also use the public cloud to back up your private cloud. Keep reading to learn about how a hybrid cloud works, as well as the pros and cons of using one.
How Does a Hybrid Cloud Work?
A hybrid cloud works by combining resources and services from two or more computing environments. It could combine infrastructure from the following:
- A public cloud with on-premise
- A private cloud with a public cloud
- On-premise, multiple private clouds, and private clouds
Regardless of the combination or setup used, all hybrid architectures have the same characteristics:
- Data integration: Your data should be synchronized and remain consistent across the different cloud environments. This can sometimes be challenging, forcing users to use additional technical solutions to keep their data consistent.
- Network connections: The public and private clouds are usually connected to each other through a private network or public internet. These connections are important since they allow you to transfer data between different environments easily.
- Unified management: All the clouds in a hybrid environment are managed by one tool. This allows you to easily monitor performance and manage resources across both public and private clouds.
Is Hybrid Cloud the Same as Multicloud?
Hybrid cloud and multi-cloud are often used interchangeably, but they are not the same. Unlike hybrid cloud, multi-cloud uses multiple public cloud services, most often from different service providers. A good example is using Dropbox and Google Drive to store and transfer documents.
Since all cloud providers are not the same, you can use a multi-cloud strategy to choose providers for specific services. This saves you from relying on a single cloud provider, meaning you can always look for better deals. Note that many organizations adopt a multi-cloud strategy by accident. It mostly happens when different departments use different public cloud providers for given functions.
Hybrid cloud differs from multi-cloud computing in one way: it uses private cloud infrastructure, along with one or more public cloud services. A good example of a hybrid cloud strategy is using a private cloud to keep sensitive customer data and a public cloud to store more general content.
What Are the Advantages of Using a Hybrid Cloud?
Many organizations prefer using hybrid cloud environments for the following reasons:
Scalability
A hybrid cloud environment allows you to scale resources up or down based on demand. For instance, you can add more computational power and run more complex applications as your business expands. This means you don’t have to wait until you can afford more servers. You can simply use the resources provided by the cloud.
Security
A hybrid cloud environment allows you to have better control over your data. You can choose where to house different datasets based on your security requirements. Most organizations store their sensitive data on-premises or in a private cloud environment and less-sensitive data in public cloud environments.
Cost
Cost is an important consideration for organizations looking to migrate to the cloud. A hybrid cloud environment is a cost-effective option since it lets you tailor your budget based on the importance and sensitivity of your data. For instance, since private cloud environments are more costly to run, you can use them to house only business-critical and sensitive data while storing less sensitive data in the public cloud. The public cloud also lets you pay only for what you use, which is a good thing, especially for companies with fluctuating demand for resources.
Speed
A hybrid cloud environment is not in itself quicker than a multi-cloud environment, but IT teams can always optimize the network to simplify the process of data transfer. You can also use the power of edge computing to make your entire infrastructure faster.
Business Continuity and Reliability
A hybrid cloud environment allows businesses to back up important data in both private and public cloud resources. This prevents data loss if one of the backups is compromised. It also speeds up disaster recovery since data is continuously replicated and refreshed to ensure data accuracy, integrity, and consistency.
What Are the Disadvantages of Using a Hybrid Cloud?
While a hybrid cloud environment has many advantages, it also has some disadvantages, meaning you should weigh your options before making your decision. Some of these disadvantages include the following factors:
Implementation
Implementing a hybrid cloud strategy can be difficult from a design and start-up capital perspective. Therefore, before starting your hybrid cloud journey, you should thoroughly evaluate your business’s needs and work with a service provider who can give you the best implementation approach.
Visibility
Cloud environments are complex. They get even more complicated when you divide your computing environments across two or more clouds. This can make it difficult for you to get a clear picture of your overall cloud environment. Without a clear understanding of your cloud architecture, you can miss out on crucial issues and opportunities, potentially failing to meet compliance regulations.
Hardware Expenses
A hybrid cloud infrastructure sometimes includes on-premises hardware for handling the computing needs of the private cloud. Setting up and maintaining the hardware can be quite costly. Although the public cloud operations can offset the hardware expenses, this is not always the case, especially for organizations with more computing requirements.
Is Hybrid Cloud Right For You?
A hybrid cloud environment has many benefits, such as scalability, enhanced security, and speed. It also has disadvantages, such as a lack of visibility, huge hardware expenses, and implementation problems. Therefore, you should weigh your options and plan well before implementing a hybrid strategy. Most importantly, you should choose your service providers well to avoid frequent downtimes.
