The 3 Main Cloud Computing Service Models
- Infrastructure as a Service (IaaS):
Companies use IaaS, which helps them to gain access to virtual machines, storage, and networks through the Internet. Each company will get these resources and be able to scale them as desired, eliminating the need to buy hardware. Common IaaS providers are Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP).
- Platform as a Service (PaaS):
PaaS provides developers with the needed infrastructure to develop, launch, and maintain applications without worrying about the hardware or servers. It also takes care of the infrastructure, making it easier to write the application. Thus, the team can focus on coding. Some popular PaaS solutions are Heroku and Microsoft Azure App Service.
- Software as a Service (SaaS):
For almost a decade, services as software services have provided software over the Internet based on subscriptions. Applications run in the browser, meaning they don't need to be installed and updated. It is easy to use and manage. Some familiar SaaS systems include communications systems (e.g., Salesforce), storage systems (e.g., Microsoft Office 365), and management tools (e.g., Dropbox).

Cloud services are also cost-reducing because they eliminate the need for expensive hardware and massive data centers. Businesses pay only for what they utilize, making budgeting easier.

Cloud tools permit work from any location with the help of internet access. You can share files, update projects in real time, and discuss instantly, which makes it perfect for organizations that have global workforces and keeps everybody in the same workspace, which leads to higher productivity.

Cloud provider implements all types of tough security measures to safeguard your data. They use all from encryption to user controls to restrict breach attempts. They also work with values for multiple industries, like finance and healthcare, which helps organizations maintain IT compliance and guarantee personal data is secured.
- Disaster Recovery
If you use the cloud, it can replicate your backups in multiple locations, meaning something can take over if something goes wrong. In a worst-case scenario, you have things somewhat protected; you are never going to lose it all due to a crash.
- Automatic Updates and Maintenance
With cloud computing, vendors will deal with the bug fixes, patches, and maintenance of systems. So, instead of having your IT team focused on maintaining the daily workload, they can focus on bigger issues. You will always use the latest version, with bugs and security holes reduced and never have to do an update yourself.
