The term ‘Cloud Computing’ is one of the most reverberated buzzwords in the present times’ technological growth. Either knowingly or inadvertently, you might have been using cloud storage and cloud computing services in your day to day life.
Cloud computing is a model that facilitates the user with global accessibility, expediency, on-demand network access to a cohesive pool of scalable computing resources (for e.g., networks, servers, storage, and critical applications) that can instantly be provisioned and released with nominal management endeavor or service provider involvement. It is basically comprises of five crucial attributes, three service models, and four deployment models.
Let’s try to connect the dots and dig deeper to know about the different types of delivery models of cloud computing
Software as a Service (SaaS)- The capability offered to the user is to utilize the service provider’s applications running on a cloud infrastructure. The critical applications are easily and quickly accessible from different types of devices through either a client-based interface (e.g., web-based email), or a program interface. The user don’t at all have to manage or control the intrinsic cloud infrastructure including network, servers, OS, storage provision, or even specific application capabilities, with the probable exemption of restricted user-specific application configuration settings.
Platform as a Service (PaaS)- Through this model of cloud, the capability with which user is facilitated is to deploy user developed or acquired applications (using programming languages, libraries, services, and tools) onto the cloud infrastructure are actually supported by the provider. In fact, the user doesn’t have to either manage or control the underlying cloud infrastructure, but has to enjoy complete control over deployed applications and perhaps configure settings for the application-hosting environment according to their requirement.
Infrastructure as a Service (IaaS)- This is the basic model of the cloud and the capability delivered to the user is the provisioning of storage, networks, and other underlying computing resources. In it, the user is empowered to deploy and run random software applications, which can include OS and other critical applications. Moreover, in this model user doesn’t have to manage or control the fundamental cloud infrastructure, but do given comprehensive control over OS, storage, and other deployed applications; and perhaps restricted control over selected networking modules (for instance host firewall applications).
Hence, navigate your business to new heights by integrating the right cloud delivery model into your existing IT infrastructure.
