You simply pay for the use of the software and then input your credentials to access the application. However, a concern is that you're entrusting a third party with your organization's data and have no control over security measures. If the vendor fails to provide adequate security then your organization's data could be compromised. Our next option is the platform as a service that provides developers with software and hardware components that can be used to build and deploy applications. According to Cloud Helix (2019), “you will not have to maintain, upgrade, or replace systems and software, and will get the best of the best when it comes to updating technology for your business to use". What this does is allows your business to focus on other areas of operation and work on improvements for future growth. Unfortunately, an issue that can arise is sometimes your current infrastructure is not necessarily built for the cloud. You may have to move some pieces around or upgrade to properly integrate. The last option we will discuss is infrastructure as a service which is where the vendor provides hardware resources that users can install and manage. So you are paying to use their equipment but can choose your operating system to run
CLOUD MIGRATION 4 and manage the environment. Now infrastructure as a service makes the user responsible for things such as backups and virtual machine management. So IaaS can be more expensive as you require more IT staff to maintain and manage systems which can be an area of concern.
