Solutions put up on the cloud have proven the sky’s the limit in IT sphere.
Everyone in IT community has been thrilled with cloud computing ever since it emerged. The benefits it brings are many: scalability, flexibility, accessibility, cost-saving, load-balancing and more.
If you take a closer look on its two models, you can see that both public and private clouds have their pros and cons one have to weigh up before adopting any of those.
Public cloud is a kind of cloud computing, in which a third-party provider owns and operates hardware and applications, which one can get access to via the Internet. This is a free of charge or pay-as-you-go service that offers numerous advantages. First of all, businesses don’t have to bear any installation or maintenance costs. You pay only for what you use. Other significant perks it offers are scalability, elasticity, and multitenancy.
All these attributes make public cloud a future proof, cost-effective service, perfect for small or medium-sized companies and startups.
On the reverse side, public cloud model isn’t compatible with all kinds of businesses.
The key downside of using it is a security concern for sensitive data.
Private cloud follows the same main principles as a public cloud but there is one big difference. It is a proprietary service, built in-house, with only one client having access to it. As a result, benefits of private cloud are enhanced security, improved reliability, and closer control gained over a server, which really matters to government organizations, financial institutions, and some large corporations which need their data to be kept safe and sound.
The downsides of private cloud are covering costs for set-up, maintenance, patching. However, this investment can prove even more cost-effective than public cloud in the long-term perspective. Another drawback is that it’s quite complicated to obtain remote access to the data sitting up on a private cloud due preventive security measures.
Hybrid cloud is a perfect combination of the two options. Going hybrid helps you to strike the right balance, bridging public and private computing environments and filling the gap between those. In fact, hybrid cloud offers the same advantages as the public cloud, including cost- efficiency, scalability and more, but it provides you as well with more flexible workload deployment options. Thus you can leverage a mix of those services, making the best use of them. For instance, a business can put its sensitive data up on a private cloud, but use a public cloud to host less critical information. Cloud bursting is one of application deployment models you can employ whilst using Hybrid cloud. When you run your application on your private cloud but you need more computing resources, you can burst your additional workload into a public cloud. Thus it helps you to orchestrate and balance data and solutions sitting up on both your public and private clouds.
Hybrid cloud comes with some disadvantages too, the main one being security compliance, which means making sure that both public and private clouds you use comply with the company’s security regulations.
Despite some complexities, so far, hybrid cloud has been a happy medium for many enterprises willing to take maximum advantage of cloud adoption, and with minimum risks.
