The Pros and Cons of Public vs. Private vs. Hybrid Cloud

Cloud computing is the latest way of storing information using a network of remote servers hosted online not only to store but also manage and process data. Organizations are relying on cloud computing today as it allows them to focus on their core business instead of spending so many resources on their IT infrastructure. The cloud is enabling companies to decrease maintenance resources and save on many upfront costs. When it comes to cloud computing, there are three types that you can choose from–public, private, and hybrid cloud. It is essential to understand their pros and cons so that you can decide which one will best fit your needs.

Public Cloud

Public cloud offers off-site solutions when it comes to hosting service models such as PaaS, IaaS, and SaaS. Examples of public cloud providers include Microsoft Azure and Amazon Web Services. These companies operate their massive data centers that are easily accessible via internet almost anywhere in the world.

The advantage of the public cloud is that there is no need to invest in computer hardware. All of the equipment needed is owned as well as maintained by the provider of the public cloud. Moreover, the scalability is also increased depending on your needs without having to raise costs dramatically. Lastly, the public cloud is pay-per-use, so you can save money by paying only for the resources that you are currently using.

On the other hand, public cloud has higher security risks because the resources are shared by multiple users at one time. With millions of people accessing the server, the network performance is also weaker. Public clouds also restrict many forms of customizations.

Unlike the public cloud, the private cloud is dedicated to a single organization.  The server is stored either offsite or within the premises. Cisco is an excellent example of a private cloud provider. Because the infrastructure is dedicated to one organization, it offers higher security and customization. It is also more reliable and efficient in delivering different service models.

There are disadvantages to using the private cloud. One of the drawbacks is that the initial cost to build the cloud is higher because of the hardware equipment needed. Infrastructures have to be built, so the operating expenses are typically higher due to the upgrade and maintenance of the machine. Lastly, remotely accessing the private cloud can create security issues, especially for the mobile users.

Hybrid Cloud

The hybrid cloud is made up of both private and public clouds. It can maintain independence while also providing coordination across different platforms. The hybrid cloud offers more flexibility because it allows you to choose where to put the IT applications and data depending on your needs. It also improves the agility of organizations, especially during outages. Both remote and mobile users can enjoy easy access to this particular cloud.

Using both public and private clouds requires complex IT management that equates to higher overall costs, and since the data can be shared by multiple users through the public cloud, it shares risks and vulnerabilities that are similar with the public clouds.
