How Does a Hybrid Cloud Work? Unpacking Its Power

It’s always difficult to get the best of both worlds. When I get dressed in the morning, I often have to lean more toward comfort, or more toward style. I find it almost impossible to achieve a happy medium.

I’ve discovered the same applies to cloud computing. A public cloud architecture is affordable and flexible, while a private cloud offers security and control. But what if I want the best of both worlds? That’s when I’d turn to a hybrid cloud infrastructure.

A hybrid cloud is the combination of two cloud computing environments: public cloud and private cloud. It’s not just about having both, however. A true hybrid cloud integrates the public and private infrastructures, so each can communicate with the other. The goal of a hybrid cloud is to maintain affordability, efficiency, flexibility, security, and control while still keeping everything unified.

Think of a hybrid cloud as a Swiss Army Knife for your IT infrastructure. You may need one tool for a specific job, while another tool makes more sense for a different job. The hybrid cloud packages all those tools into one solution.

I’ll show you how it all works — like how hybrid cloud compares to other cloud options, the core features of a hybrid cloud, and even use cases for the hybrid cloud.

A hybrid cloud brings together the benefits of public and private clouds. Your organization may need to protect sensitive data in a private cloud but also require scalability for highly sensitive data during high-traffic periods (public cloud). That’s where the hybrid cloud comes into play.

To help you understand further, I’d like to showcase how a hybrid cloud solution differs from a standalone public cloud, a standalone private cloud, and a multicloud solution.

Similar to transportation, cloud technology has evolved and improved to suit growing demands. Some people drive their own cars (let’s call that the private cloud). Others prefer to ride the bus or take Uber (the public cloud).

Now we have more advanced hybrid and electric cars that provide benefits from everything that came before. That’s exactly how I view the hybrid cloud. It’s not going to be the least expensive, or the easiest to implement, but it helps get you close to the “best of both worlds.”

My first encounter with a hybrid cloud system was a bad one. It was years ago when the most modern version of a hybrid cloud simply meant using both public and private clouds side by side, without any integration.

Luckily, things have improved since then. In fact, the whole point of a modern hybrid system is to offer fluidity of data movement and a unified, centralized control center. I’ll explore that, along with the other characteristics of the hybrid cloud, below.

Integration of Public and Private Clouds

A solid hybrid cloud integrates public and private cloud systems so they both work together in communicating back and forth. They’re still most likely different systems, but the goal is to make a unified system with benefits from both private and public clouds.

Here’s what I expect from a high-quality private/public cloud integration:

• Options to pick the best cloud environment for each dataset or workload
• Performance consistency across every platform used
• Centralized control over both private and public clouds
• Seamless movement of data from public to private clouds and vice versa
• Unified security policies

A strong integration between public and private clouds works similarly to a rock band. All the instruments and artists must complete their own unique roles, but it’s just as important that their individual parts combine into a fluid piece of music. If one piece doesn’t integrate well, you’re left with a poorly configured hybrid cloud.

Data and Application Portability

That integration I discussed above facilitates the seamless movement of data between public and private clouds. And that’s a key feature of any good hybrid cloud. It must transfer data and applications between both environments without a hitch.

I see several advantages in such seamless portability:

• You can migrate workloads easily
• It’s easier to scale resources
• It improves disaster recovery capabilities
• You can decrease costs by moving data and workloads to the cheaper environment

You should never get stuck with an application or piece of data on one cloud system. A hybrid cloud is meant to provide portability. So, if there’s a sensitive piece of data that ended up on your public cloud, you’ll want a streamlined solution for bringing it back to the private cloud as soon as possible.

Centralized Management

It’s a recipe for disaster when you try to have two separate public and private clouds. Without a centralized management system, it’s difficult to move data, make backups, and maintain security practices across both infrastructures. Luckily, modern hybrid cloud tools offer centralized management.

Some centralized management features to look for:

• Continual monitoring and statistics
• Unified security and policy management
• Snapshot views of your entire infrastructure from one place
• Automation for things like optimization and resource allocation

Many hybrid systems already come with centralized management dashboards. But every so often you need to combine entirely different public and private cloud interfaces to make your own hybrid infrastructure.

In that case, consider tools like Flexera, AWS, Microsoft Azure, Google Cloud Console, and Cloudify to manage hybrid environments cohesively.

My first experience with a hybrid cloud introduced me to cost optimization and scalability. I was able to forgo the exclusive use of a private cloud for a more affordable public cloud, while also having the option to scale up with a third-party cloud service. The hybrid cloud offers a wide range of benefits, all of which I’ll explore below.

Scalability and Flexibility

Within a hybrid environment, I can scale up or down depending on traffic changes. It’s also possible for me to remain flexible with my resources thanks to the public side of the cloud and its smooth integration with the private side.

Here’s how the hybrid cloud makes your operation more flexible and scalable:

• It offers support for quick testing and prototyping
• You’re able to expand into new markets and regions with ease
• The hybrid model supports sudden traffic spikes
• You can allocate resources on demand

Think about the advantages for so many businesses. With the flexibility and scalability of the hybrid cloud, eCommerce businesses can expand into new markets. Developers can prototype without any trouble, and any application can withstand spikes in traffic.

Cost Optimization

I like to think I’m a savvy shopper. Black Friday deals, coupons, and discounts on yearlong agreements — they’re all part of my strategy to save money.

When it comes to the cloud, however, you’re often stuck between a cheap, less secure option that takes control away from the user (public cloud) and an expensive solution without much flexibility (private cloud).

That’s why I love the hybrid cloud. I can save by buying private cloud solutions in bulk and only paying for the public cloud when needed.

As a result:

• There’s only a continual bill for the public cloud resources used
• You cut down on capital expenses needed for private cloud hardware
• You put your data and workloads in the most cost-effective environment

It’s a balancing act, but one that saves you money in the short and long run. The key is to implement a strategy that uses the private cloud for your everyday, in-house needs, while renting whatever public cloud infrastructure you need.

Enhanced Security and Compliance

Besides cost optimization, using a combination of private and public cloud systems allows for the protection of sensitive data.

At the same time, you can open up the freedoms (and cost efficiencies) of the public cloud for less sensitive data and tasks. The private cloud also helps with compliance.

Here are the key security and compliance benefits of a hybrid cloud:

• Enhanced threat detection
• Improved compliance capabilities for regulated markets
• Unified security policies, along with customizable security options based on the cloud system
• Data segregation for sensitive information

I like to picture the security of a hybrid cloud as a safe within a safe. You have your public cloud infrastructure for regular tasks and data — items that don’t need extreme protection. But then you’re able to lock the more important stuff — legal documents, payment information, and proprietary plans — inside the private cloud.

Business Continuity

The continuity of your business means making it available at all times.

I never want my application to struggle with accessing user data. I never want to see my eCommerce website go offline. No business wants to experience downtime, and that’s why the continuity of the hybrid cloud is so helpful.

The hybrid cloud creates continuity with:

• Environments to develop and test without having to impact live sites or applications
• Geo-redundant storage for data
• Failover mechanisms that respond rapidly
• Multiple recovery tools

You’re bound to encounter challenges with your business. The key, however, is to take those challenges head-on and ensure your systems remain accessible while you recover from disasters. The hybrid cloud gives you the best opportunity to do that.

If I’m being honest, my first-ever attempt at implementing a hybrid cloud was an absolute nightmare. I underestimated the complexity of the integration, struggled with cost management, and had a tough time enforcing consistent security policies.

With all mistakes, however, come learning opportunities. To avoid my errors, I’ll explain the challenges you can expect to encounter, along with tips on how to stray away from similar issues.

Complexity in Implementation

Every cloud environment is unique in its own way. Vendors try to make it difficult to integrate with other cloud systems, and I’ve found that connecting any type of cloud platform to another requires significant planning.

Here are some challenges you may encounter:

• Having to train staff on new cloud tools and processes
• Maintaining consistency in security policies across cloud systems
• Staying connected on your network and minimizing latency
• Making sure your cloud system can integrate in some way

And it’s not just about integrating your tools. The goal is to make a cohesive environment, so every cloud platform works in tandem and in harmony. Do your best to identify cloud systems that already work well together.

Data Security and Governance

If there’s one thing you should be worried about with a hybrid cloud, it’s maintaining a consistent security and governance policy. There are so many challenges to consider:

• Maintaining a high level of data integrity as you move data between your cloud systems
• Creating and enforcing access controls that remain consistent across cloud systems
• Maintaining consistent authentication tools
• Keeping data private and compliant for all cloud environments

Here’s the thing: You need to establish uniformity when it comes to data security and governance. Otherwise, you’re bound to have troubles with compliance, data integrity, and security.

Begin with a public cloud provider that integrates seamlessly into private solutions, or consider (even at the risk of vendor lock-in), picking both private and public clouds from the same company.

Cost Management

Here are the main cost management challenges I’ve encountered with hybrid cloud systems:

• Complex pricing models from some cloud providers that don’t align with other providers
• Allocating resources to the right cloud systems to ensure I’ve minimized costs and not wasted money with the wrong placements
• Avoiding over-optimization or provisioning in both public and private clouds
• Keeping data transfer costs low

If you fail to take on these challenges, you’ll end up spending far more money on a hybrid cloud solution than you ever spent on a private or public cloud.

Luckily, I’ve found that system monitoring works best for keeping my budget under control, particularly when it comes to allocating the right resources to the less expensive public cloud instead of the private cloud.

Vendor Interoperability

Unfortunately, vendor lock-in is a reality you must deal with. Cloud vendors are no different. They make proprietary APIs, unique tools, and protocols that don’t play well with other cloud systems. And it’s all to force the user to remain loyal.

Even worse, businesses tend to get stuck in vendor lock-in more frequently, thanks to the risk of downtime and lost revenue. In short, cloud products may not work well together.

Here are the challenges that come with that:

• You need to deal with vendor lock-in and portability problems, even when using cloud vendors that claim they won’t lock you in
• You have to manage multiple SLAs
• Each vendor has their own customer support processes
• You need to ensure data compatibility across platforms and management interfaces

If you overcome these challenges of interoperability, you’re a big step closer to building a cloud system that’s truly hybrid. As you may remember me mentioning a few times before, it’s not just about integrating your cloud tools. It’s about making those tools seamless, allowing them to work together as smoothly as possible.

The seamless nature of a high-quality hybrid cloud doesn’t happen by accident. It’s all thanks to cutting-edge tools that come together for a cloud environment that’s both efficient and unified.

Here are my favorite technologies involved in the hybrid cloud infrastructure:

All these technologies make cloud infrastructures smarter, especially in the realm of hybrid cloud platforms. From containers to AI, I want you to remember all the components that go into such an intricate system. This way, you’re able to better understand it all and avoid mistakes like I’ve made in the past.

All of this information about the hybrid cloud may get you wondering, “how does it apply to the real world?”

In this section, I’ll talk about the most common instances of the hybrid cloud and how you might use it for your own organization.

Data-Intensive Applications

The hybrid cloud just makes sense for big data processing and analytics. I’d argue it’s one of the most compelling cases to use a hybrid cloud. It’s similar to having a supercomputer that makes calculations and moves large batches of data on demand.

You can also scale with the capabilities of the public cloud while still maintaining control over your sensitive data.

Here are my favorite use cases of the hybrid cloud in the big data world:

• Media processing and rendering for streaming and entertainment apps
• Risk analysis and financial modeling
• Computations for research and simulations for science
• Real-time eCommerce analytics for predicting sales and growth

The hybrid model provides several advantages to big data companies and industries. It allows you to protect sensitive data, and you can scale with large amounts of data, all while maintaining control over the entire unified system.

Regulatory Compliance

If your business needs to comply with regulations like HIPAA, GDPR, or PCI DSS, it’s wise to store your most sensitive data on private clouds. In fact, you may be required to do so by law.

That’s particularly true if we’re talking about a regulation like PCI DSS, where eCommerce stores, and any business collecting payment information, must abide by rigorous storage requirements.

The hybrid cloud model can help you achieve HIPAA, GDPR, and PCI compliance if you configure it properly.

At the end of the day, you still have the opportunity to use public clouds if you need to scale faster with your non-sensitive data. Otherwise, a hybrid cloud comes with many benefits for complying with regulations.

It’s easier to meet regional regulations, maintain flexible encryption options, and adapt to changing regulations.

Development and Testing

I’ve seen it countless times: a developer uses a sandbox environment to test new features before going live with a project. That’s how a hybrid cloud environment helps with development and testing.

Here are some real-world situations:

• Load testing that’s cost-effective
• Simple staging and production
• Immediate replication of sandbox conditions
• Fast provisioning for test environments

In short, you can innovate quickly with a hybrid cloud. There’s no need to break anything important, since your production environments remain in the private cloud and all testing gets messed with on the public clouds.

Disaster Recovery

With the continuity of a hybrid cloud, I’m able to recover from a disaster much quicker. Here’s how:

• Automated mechanisms for failovers
• Consistent disaster recovery testing without causing harm to the production environment
• Easy scaling for recovery resources
• Quick data replication across multiple cloud environments

Any cloud environment I’ve worked with keeps the most important stuff in a private cloud. You also can test things in a public environment. Those help you avoid disasters. But when it’s all said and done, you can also recover data so much easier with a hybrid cloud.

I can’t predict the future, but with the hybrid cloud, it’s easier to see what trends to expect, especially considering some of them are already in their infancy. I encourage you to take a hard look at these trends, since they’re bound to shape how we understand hybrid cloud and computing in general.

Hybrid AI Workloads

Whenever I use a hybrid cloud, I can’t help but think about the possibilities for artificial intelligence. You could train a language learning model on all your public cloud data but also keep everything in the private cloud as untouched as ever.

Here are some ways I see AI merging with the hybrid cloud:

• Governance and compliance
• Automated security across clouds
• Edge computing
• AI training across hybrid clouds

I see the use of AI in the hybrid cloud as a pivotal tool in finance, healthcare, and many other industries. It’s also definitely going to make a difference in the big data world.

Edge Computing Integration

Edge computing allows for real-time processing. That’s particularly important for high levels of data in the IoT and hybrid cloud worlds. I expect to see more integrations with hybrid clouds and edge computing, particularly for:

• Rapid decision-making
• Improved security for all edge data
• Superior data flow between cloud, private, and edge clouds

The objective is not to simply integrate the hybrid cloud with edge computing, but to extend its functionality to include edge computing in a seamless manner. You might even see this combination in smart cities and self-driving vehicles, thanks to its fast data processing.

Hybrid Cloud and Sustainability

I try my best to care about the planet but, as many of us know, large data centers and faster computing models make it rather difficult.

I’m in the tech space, which is notoriously bad for the environment. But that’s all the more reason to get excited about how the hybrid cloud can help with sustainability.

From intelligent workload placement to carbon-aware computing, I expect brands to adopt more energy-efficient hardware and renewable energy sources across the board.

I’ve established that a well-implemented hybrid cloud is good for business. It’s cost-efficient, high speed, and well-balanced for things like security and scalability.

If you’re in the market for a hybrid cloud solution, I recommend you start by looking at your current systems. Would it be possible to just go with a private or public cloud system first? If not, what tools will you use to make your hybrid cloud as seamless as possible?

After all, that’s the point of a hybrid cloud: seamlessness.

I’ve shown you all I know, from how a hybrid cloud helps big data and rapid task management. Now, it’s time for you to take the next steps of finding the perfect hybrid cloud solution for your business.
