Software as a Service, also known as SAAS or SaaS, is a cloud-based service where you access an application via an internet browser, instead of downloading it on your desktop PC. This unique delivery model for applications offers unique advantages.
SAAS applications are more accessible, convenient, and easy to use. They also offer lower upfront costs than the traditional software download and installation, making them more available to a wider range of businesses. Instead of buying the license, users “rent” the software by paying a subscription fee.
Existuje mnoho different kinds of SAAS applications out there. And they make it easier to access different types of services without having to worry about installation, maintenance, data security, etc. It is all handled by the SAAS provider. You don’t need to keep the app updated because that is done for you as well.
SAAS is not a plug-in to other applications, nor is it a way to build apps: it is a full application that can be used for a wide variety of purposes. Here we will talk about whether SAAS is a public cloud or a private cloud. But first, let’s discuss what public and private clouds are.
What is a Public Cloud?
Public clouds are cloud services offered to multiple customers by a cloud provider. Public clouds are managed by third-party providers and are shared among multiple customers, unlike private clouds.
Like all cloud services, a public cloud service runs on a remote server that is managed by the provider. Customers can access these services over the Internet. Even though multiple customers are using the service, each customer’s data and applications running in the cloud are still hidden from other cloud customers.
With a public cloud, you are not responsible for the management of a public cloud hosting solution. Your data is stored in the provider’s data center. They are also responsible for the management and maintenance of the data center.
Many companies choose this type of cloud environment. That is because it reduces lead times in testing and deploying new products. However, some companies may feel that their security is lacking in a public cloud. This is why some of them opt for a private cloud instead. Most cloud service providers ensure data security through a number of means.
Large companies may go for a private cloud for extra security, while smaller businesses tend to gravitate towards a public cloud because it is cheaper and more accessible.
What is a Private Cloud?
A private cloud is a cloud service that is not shared with any other organization. With a private cloud, you have the cloud all to yourself. It is a private cloud hosting solution that resides in the company’s intranet where all of your data is protected behind a firewall.
If your company already has an expensive data center, you may want to use your current infrastructure, so you should go for a private cloud instead. The main drawback here is that your company has to take charge of the management, maintenance, and updating of data centers.
Over time, your servers will have to be replaced, and that can get very expensive. But private clouds offer an increased level of security because it shares very few, if any, resources with other organizations.
Is SAAS Public or Private Cloud?
Most SAAS are public cloud. But by definition, any service that is not in your premises is considered SAAS, so services run in a private cloud may also fall in this category. Where a SAAS is hosted does not matter: it could be public, private, or even hybrid.
This means it is not necessary for the system to be hosted only on the provider’s servers. Keep in mind that the cloud itself is not a product, but a way to deliver digital resources. The public and private alternatives are only referring to who has access to these resources. Consider what will work best for your company in terms of security, functionality, and maintenance.
