Hybrid cloud is getting a lot of attention, but the majority of efforts are converged on only few use cases. To wrap a definition around hybrid cloud, it represents interdependent environments hosted across private data centers and public clouds such as AWS, Microsoft Azure and GCP. This cloud model came into existence due to the dynamic needs of enterprises; which includes keeping certain workloads on premises while enjoying the benefits cloud has to offer.
Here are the most common use cases of hybrid cloud and seasoned information on the requirements and advantages on each use case:
1. High Availability and Disaster Recovery (DR)
This might not be the most exciting use case but surely the most common. In this case, IT teams just need to mirror their on-prem infrastructure implementations in the cloud. If the operations in on-prem data center are disrupted, then applications could failover to the cloud and continue to run without noticeable glitches to users.
The hybrid cloud can also be architected for high availability. To do this, enterprises need to use load balancers which distributes traffic between on-premises and cloud environments as needed.
Running mirror environments might be too high-end in terms of cost. This is why this particular use case has its own limitations. Hybrid clouds might limit you to fully utilize cloud-based services because the workloads also require environment parity.
2. Migrating workloads to and from the cloud
The enterprises concerned over the migration issues can leverage hybrid cloud model, although, temporarily. Migration is not a one-day task or that could be done overnight. It can take from days to weeks to months to complete with several phases of migration and validation. Enterprises with heavy workloads needs the flexibility to be able to quickly roll back a change.
In this use case, you can leverage hybrid cloud to start the move without even changing everything at once. Hybrid cloud could perfectly lay the groundwork with the ability to check the optimal services and resources for workloads by migrating applications to and from the cloud.
3. Development and Testing Ground
Several organizations have various dev and test projects in hands. Dev Teams need to do test, development tweaks without giving hefty bills to the finance teams. Hybrid cloud’s one of the most common use case it to provide such environment where testing can be done as often as necessary to develop a flawless product.
Dev and test environments in cloud are quite popular due to two factors. First, obviously it is cost effective and cloud allows you to pay-as-you-go that too for only what you have used. Secondly, teams can quickly provision resources whereas, to run such environments on-prem requires procurement process for necessary hardware and software; which can take months.
4. Cloud as data center extension
In this use case, cloud can act as an additional support while on-prem handles the primary workloads. This use case is widely used in healthcare sector. How? Well, a simple scenario involves the patient monitoring handled on-prem to prevent latency issues. Here, cloud can act as a back end, where the information collected from monitoring patients can be combined with other large data sets to support advanced diagnostics.
Another factor which led this use case into play is the privacy constraints. There might be internal policies or government mandates involving the movement of data across regions. To tackle the end-user latency issues, organizations deploy necessary workloads in cloud, particularly regions near the end-user.
Hybrid cloud can help you embrace cloud computing
It is never easy to come out of already set-up legacy infrastructure on which organizations are running applications for past several years. But it is all about updating the tech stack to get the competitive advantage. There have been several scenarios where new businesses have outcasted already set-up organizations just with an advanced stack of technologies. Such advanced technology is cloud computing which proliferates entirely new ways to do business.
Well, hybrid cloud can help you get in the shoes of a company that leverages cloud without letting go on-prem data centers. So, assess, analyze and plan to get a grip of your cloud fear only for the bright future of your business.
