Hybrid cloud is a mixture of two or more types of cloud architecture. Hybrid cloud architecture combine public cloud and private clouds. And they can even include on premises legacy infrastructure. For a cloud to truly be hybrid, these different cloud architecture must be tightly interconnected with each other, essentially functioning as one combined infrastructure. In most of cases, all hybrid clouds include at least one public cloud.
A hybrid cloud is somewhat like a hybrid car. Hybrid cars combine two totally different technologies: an engine that consumes gasoline and electric power. Each technology features in a totally different way, and each one has its own advantages and disadvantages. However, when the two are combined properly. The result is a car that is more efficient than most gasoline only cars and yet more powerful than most of electric cars. Similarly, hybrid clouds combine the benefits of multiple types of cloud environments for greater efficiency and functionality.
Hybrid clouds have a number of benefits. A company may use their private cloud for some services and their public cloud for others. Or they may use the public cloud as backup for their private cloud. They can also use the public cloud to handle periods of high demand, while keeping most operations within their private cloud.
How do hybrid clouds work?
The way public clouds and private clouds work in hybrid cloud are same way how they work in standalone public clouds or private clouds work:
➟ A local area network (LAN), wide area network (WAN), virtual private network (VPN), and/or application programming interfaces (APIs) connect multiple devices together.
➠ Virtualization, containers, or software-defined storage abstract resources. This pools data lakes.
➟ Management software allocates those resources into environments where applications can run. Which are then provisioned on demand. With help from an authentication service.
A cloud become hybrid when those environments are connected as seamlessly as possible. That interconnectivity is the only way hybrid clouds work. It is why hybrid clouds are the foundation of edge computing. This interconnectivity is how workloads are moved, management is unified, and processes are orchestrated. How well-developed those connections are has a direct impact on how well your hybrid cloud going to works.
What is the difference between hybridcloud and multicloud?
A multi-cloud can also be a hybrid cloud, and a hybrid cloud can also be a multi-cloud. But these terms represent two different concepts. A multicloud deployment combines multiple public clouds. While a hybrid cloud is mixture of a public cloud with another type of environment. Hybrid clouds combine apples and oranges, a multicloud deployment is more like combining many types of apples. In addition to using multiple public clouds, just as a rectangle can be a square, but not all rectangles are squares. Conversely, a hybrid cloud infrastructure can also be multicloud if it uses several public clouds.
Who uses hybrid cloud?
Companies across the spectrum of industries have moved toward hybridcloud solutions to reduce costs and strain on local resources. From the financial sector to the health care sector, hybridcloud infrastructure have proven to be effective at not only improving computing and storage power. But also optimizing the scarce resource of physical space. Many companies simply do not have the room available to deploy servers on-site.
In the health care sector, data privacy is paramount, and privately held computation resources are even lacking. A hybridcloud architecture is a perfect solution because it allows medical compay to retain patient data in a secure, private server while simultaneously leveraging the advanced computational power of a public IaaS model. Simply put, any sector that benefits from public cloud applications can also benefit from the hybrid model.
Benefits of Hybrid cloud
Hybridcloud architecture enables a company to deploy its most sensitive workloads in an on-premises cloud and to host less-critical resources on a third-party public cloud service provider. This approach allows business to get the best of both private and public cloud architecture. The main features of hybrid cloud is:
Users work with various types of data in disparate environments and adjust their organization. A company can use a hybrid cloud that works for it’s needs, using traditional systems as well as the latest cloud technology, without a full commitment to a vendor. Organizations savvy with a hybrid cloud setup can migrate workloads to and from their traditional infrastructure and a vendor’s public cloud whenever necessary.
Agility and scalability
Hybridcloud offers more resource features via a public cloud provider vs. an company’s physical data center. This makes it easier to provision, deploy and scale resources to meet demand spikes. When demand out come capacity of the local data center, a company can burst the application to the public cloud to access extra scale and capacity.
To increase resiliency, a organization can run workloads repetitiously in both private and public cloud services. Components of one workload can even run in both cloud and interoperate.
Potential cost savings
With a private cloud, company own and operate the data center infrastructure, which requires significant capital expense and fixed costs. However, the public cloud offers resources and services. Which are accounted as variable and operational expenses. Hybrid cloud users have option of running workloads in whichever environment is more cost effective.
Compliance restrictions on where data can reside mean companies in highly regulated industries can’t move all workloads to the public environment. With hybridcloud, organizations can keep data in a private cloud. While operating workloads in the cloud, or they can operate workloads in a private data center and move data to and from the public cloud as per need. This allows companies to meet regulatory requirements and still benefit from the elasticity of the cloud.
How is hybrid cloud managed?
Managing hybrid cloud is not that easy task as each cloud solution has its own API, storage management protocols, networking capabilities, etc. Mastering each solution’s complexities is possible. But perhaps not sustainable. Because of this, professionals responsible for hybridcloud management often construct a single interface to manage all cloud services seamlessly.
Building such an interface needs a team that is familiar with handling cloud solutions and getting disparate networks to communicate effectively. Fortunately, enterprise-grade management tools are available to help IT managers get their system up and running.
Why are hybrid clouds so popular?
Because user can use the best of every cloud in hybridclouds. Command Line Heroes host Saron Yitbarek investigates how open source can connect multiple environments into a hybrid cloud.
