- Speed and Agility – Cloud computing services can quickly give businesses the resources they require. This faster deployment means that you get the resources you need right now, reducing the time it takes to make those resources available to your developers from weeks to just minutes.
- Productivity – Cloud computing removes the need for many of the tedious manual tasks. It allows IT teams to spend more time on achieving more important business goals.
- Performance – The biggest cloud computing services run on a worldwide network of secure data centers, which are upgraded to the latest generation of fast and efficient computing hardware. This offers several benefits over a single corporate datacenter, including reduced network latency for applications and greater economies of scale.
Understanding the Three Core Cloud Computing Services
Cloud computing offers three core services to meet various user demands:
- Software as a Service (SaaS): This model delivers cloud-based applications to users on-demand. A single instance of the service on the cloud caters to multiple end users.
- Platform as a Service (PaaS): Prominent among developers, PaaS provides the components necessary for app development, including tools, database management, and business intelligence services.
- Infrastructure as a Service (IaaS): IaaS offers the complete cloud computing infrastructure — servers, network, operating systems, and storage, accessible via a dashboard or an API. Users have direct access to their servers and storage as if they were in their own datacenter.
These services, often termed as the cloud computing stack, are versatile and build on each other. Their adaptability, along with the familiarity of traditional office applications, makes them an appealing choice for businesses.
