No question about it, cloud computing is here to stay. Considering migrating to the cloud is just the beginning, however. Three models to consider–IaaS, PaaS and SaaS–offer varying levels of shared responsibility between provider and customer. Read on to learn more about the three models, and to get an idea which is the best for your business.

Cloud Service Models–Benefits and Responsibilities

Infrastructure as a Service, or IaaS, requires the cloud service provider to establish the network and its connections. With this model, a company can have their provider maintain and operate the infrastructure; the client will still need to keep their operating system current, configure their platform to meet requirements, and control how information is handled and stored. A company using IaaS will have more flexibility, but will need more technical and security expertise and assistance. Moreover, the company needs to take on administrative roles for system level security.

The Platform as a Service (PaaS) model provides hosting and tools on which applications can be developed, and the provider is responsible for furnishing a user interface. The client is responsible for controlling administrative access to certain portions of computing resources, and also oversight of applications built on the platform. Also, the client needs to keep the platform current with operating system patches, and implement a cloud security strategy to protect their applications.

If a company chooses Software as a Service (SaaS), they will have more responsibility for maintaining user security and may take on some administrative roles for the application. While the provider handles the infrastructure, keeps the software applications up to date and provides hardware and software tools over the Internet, many security considerations remain with the customer. Your company will need to train employees in awareness about keeping the network secure, implementing a strong password policy and possibly a zero-trust environment where each log-in to the network is verified.

Whichever model your company chooses will depend on your budget, level of staffing and ability to take on certain responsibilities for maintaining a strong, healthy network. For more guidance in choosing the most appropriate model, contact us today.
