Cloud Computing Service Models

Cloud computing is a relatively new industry that still made $272 million in 2018. MarketsandMarkets estimates that the industry will reach $623.3 billion in 2023. Cloud computing services models are all to be commended.

Cloud computing deployment models have helped cloud computing diversify. Cloud computing is used in many other industries, including smartphone development, online streaming video, social media, and application development.

How can cloud computing help so many industries? Continue reading to learn more about cloud computing service models and their various functions.

Cloud Computing Service Models 1 – Infrastructure as a Service
Infrastructure as a Service, or IaaS, is one of the most popular cloud computing service models. It replaces on-premise computing resources. These computing resources are data centers, servers, networks, or network devices.

It does all that an on-premise platform can do. The difference is that IaaS clouds offer computing resources.

IaaS is more popular than traditional on-premise platforms. This is due to the low cost and system flexibility. It is much easier to upgrade computing resources in IaaS.

Upgrades in on-premise platforms can be costly and difficult to install. All responsibility for the on-premise platform falls to the business. This includes the hiring of manpower, maintenance, and hardware. However, third-party providers manage cloud computing models like IaaS.

Cloud Computing Service Models 2, Platform as a Service

The Platform as a Service (or PaaS) is another major cloud computing model.

PaaS is a cloud-based service that provides program development tools to businesses. These program design tools can be used for any type of computer program or application.

Windows Azure and Apache Stratos are two examples of PaaS-based platforms.

PaaS allows you to reduce the cost of developing apps or software by using resources provided by other providers. You can also scale it, since the service can either downsize or increase its size depending on your company’s budget.

A PaaS model is more user-friendly for developers. Cloud computing service models make it much easier to create apps or software.

Cloud Computing Service Models 3 – Software as a Service
Software as a Service (SaaS) is another type of cloud computing service model. This is also known as Software-as-a Service.

SaaS is the most well-known cloud computing service model. KBV Research predicts that the global SaaS industry will grow to $185 billion by 2024.

Software as a Service platforms offer software over the Internet. SaaS platforms include Google Apps, MailChimp and DocuSign.

These platforms make it easier to install apps on your devices. Software as a Service can be accessed via a browser.

Cloud Computing Service Models 4, Backend as A Service
Mobile has seen an exponential growth. It has grown to such an extent that another type of cloud computing service model was added.

The Backend as a service is an additional type of cloud computing service model. It’s also known as BaaS. Sometimes it is referred to as Mobile Backend as Service. Because it serves mobile device developers, this is a common name. This is also a relatively recent frontier in cloud computing service models.

BaaS platforms offer backend capabilities for mobile and web programs. These backend features include remote updating, push notifications and user authentication.

BaaS has been enabled, and the only thing the developer needs to do now is to create the frontend. This frontend consists of the user interface and client-side logic.

Cloud Computing Service Models 5 – Serverless Computing
The serverless computing model is another option to cloud computing. The service provider runs the server in this model.

Pricing is an essential part of this service model. Users only pay for the actual use of their service. So, uses are not required to pay for downtime since they haven’t used any service during such period.

It does not eliminate the need for servers. Serverless computing does not eliminate the need for users to think about the resources required to complete tasks. The service provider now maintains the servers.

Function as a Services also uses serverless computing. FaaS is another abbreviation. It is an additional addition to cloud computing model models.

FaaS allows users develop apps and to execute functions without the need for infrastructure. This allows for faster processing. This is one the most revolutionary cloud computing service models.

All cloud computing models depend on at least one server. FaaS platforms, however, only run the server when certain functions fail. This greatly reduces the time it takes to manage server logistics.

Cloud computing is well-known for its flexibility. This flexibility is also why cloud computing deployments are so diverse.
