Cloud computing is one of the most emerging technologies. It can make our lives much easier. But, there are a number of security concerns about cloud computing. And if they are not taken care of properly, they can cause serious concerns. Let’s discuss some of the most common security concerns of cloud computing in this article.

Types Of Cloud

There can be the following types of clouds.

As per services offered :

In the IaaS cloud service model, the cloud service provider provides infrastructure or hardware as a service. The infrastructure can be managed over the Internet. By availing IaaS, a company can avoid the cost of purchasing or managing physical servers. Examples of IaaS include Amazon AWS, Microsoft Azure, Rackspace, Google Compute Engine, etc.

If the cloud service provider offers a development platform that includes an Operating System, a programming language execution environment, a database, a web server, etc,. it is called Platform as a Service or PaaS. In other words, PaaS provides a computing platform where developers can run, test, and manage software applications. Examples of PaaS include Google App Engine, Salesforce, Apache Stratos, Magento Commerce Cloud, etc.

If the cloud service provider offers access to software applications on a per-user basis, it is called Software as a Service or SaaS. The software can be accessed and managed from anywhere over the Internet. Examples include Microsoft Office 365, Slack, Cisco WebEx, Google GSuite, etc.

SECaaS is inspired by the SaaS cloud service model. In the SECaaS cloud service model, the cloud service provider provides security as a service. For example, the cloud service provider can provide Data Loss Prevention (DLP), Identity and Access Management (IAM), vulnerability scanning, email security, SIEM, or business continuity and disaster recovery as a service. Examples of SECaaS service providers include Cloudflare, Incapsula, etc.

In XaaS, the cloud service provider can provide anything as a service. For example, the cloud service provider can provide database as a service, communication as a service, network as a service, storage as a service, desktop as a service, etc.

As per deployment models : 

On the other hand, as per deployment models, there are four main types of clouds.

Private clouds operate solely for a single organization. They can be managed internally or by a third party, hosted internally or externally.

In a Public Cloud, services are rendered over a network that is open to the public.

Community Cloud shares infrastructure among several organizations from a specific community with similar concerns like security, compliance, jurisdiction, etc. They can be managed internally or by a third party, hosted internally or externally.

A hybrid cloud is a composition of two or more clouds, like private, public or community. It offers the …
