When deciding to use cloud computing for your business, there are usually three models of cloud service to consider: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Reyna ITS has expertise in each of these three cloud models and can help you decide which would be most beneficial for your business.
SaaS (Software as a Service) allows people to access and use software applications over the Internet. Email, calendar applications, and productivity tools, such as Office 365, are typical examples of a Saas cloud service model. Instead of purchasing software outright, users rent access to the application.
This model eliminates the need for companies to install and run applications on their own computers, reducing the expenses that come with hardware acquisition and maintenance, as well as software licensing, installation, and support. Other benefits of the SaaS model include flexible payments, scalable usage, automatic updates, and access to a wide range of applications to suit organizations of any size.
PaaS (Platform as a Service) is a complete application development and deployment environment in the cloud which offers many advantages to premise-based development environments. In a PaaS cloud service model, the PaaS provider hosts the hardware and software used for application development on its own infrastructure and delivers it to its users as a service.
Through this model, users are able to develop or run a new application without having to install in-house hardware and software. Middleware, database management systems, business intelligence systems, development tools and other powerful resources are provided in the PaaS model, which help developers stay up to date with frequent changes and upgrading operating systems, and allows teams to easily collaborate on projects.
Other benefits of the PaaS model include flexibility to scale as needed, the cost savings of a pay-as-you-go model, ease of maintenance, and reduced time to market for development projects.
IaaS (Infrastructure as a Service) is a cloud computing service model that provides virtualized computing resources of any size over the Internet. The IaaS provider hosts the hardware, software, servers, storage, and other infrastructure components on behalf of its users.
IaaS is often used for high performance computing, big data analysis, development and testing environments, storage, backup and recovery, and website hosting that requires considerable resources.
IaaS offers highly scalable capacity that can be adjusted on-demand. You pay only for what you consume, reducing capital expenditure and ongoing maintenance costs. IaaS allows you to focus on your core competencies, innovate rapidly, improve security and continuity, and respond instantly to the varying demands in your business.
