Four Different Types of Cloud Computing Services

Cloud Computing

All public cloud computing services are developed on the same conceptual structure of remote infrastructure controlled by servers saved in a data center. Since there are several similarities between them, it is beneficial to consider cloud computing as a hierarchy made up of three layers.

Each layer handles a specific target than the other beneath it though it is created on the same fundamental structure. The lower layers are wider which is a representation of their versatility is, personalization, and wide range of applications whereas the top layers are smaller because they are created for a specific task. Dark horse systems provide the best cloud computing services and here are the four types.

Infrastructure as a Service (IaaS)

As the base of the cloud computing pyramid offered by dark horse systems, IaaS is the easiest to understand and versatile type of cloud service available. Essentially, it offers a complete virtualized computing infrastructure that is created and controlled over the internet. An IaaS provider controls the physical end of the infrastructure which includes; servers, data storage space amongst others in a data center, but let customers completely personalize those virtualized resources to fit one’s specific needs.

With the service, the customer can buy, install, configure, and control any software they require including kinds of stuff like; operating systems, middleware, applications, business analytics, and development tools. Examples of IaaS include Microsoft Azure, Amazon Web Services (AWS), Cisco Metacloud, and Google Compute Engine (GCE).

Platform as a Service (PaaS)

Located a little bit higher than the cloud computing pyramid is PaaS. IaaS provides all the tools needed via the cloud and lets customers build whatever meets their needs while PaaS offers the structure required to create, test, organize, control, and update software products.

It uses the same fundamental structures as IaaS, but it equally consists of the operating systems, middleware, development tools, and database management systems required to develop software applications.

PaaS is exceptionally useful for any company that builds software and web-based applications. Many of the tools needed to create for multiple platforms like computers, devices, browsers, just to name a few can be pretty costly.

By using PaaS, customers can have access to the development tools they require, when they require them, without having to buy them instead. Examples of PaaS are AWS Elastic Beanstalk, Apache Stratos, Google App Engine, Microsoft Azure.

Software as a Service (SaaS)

SaaS is a popular cloud computing system located at the top of the pyramid. It contains a complete-developed software solution that is ready for sale and uses over the internet on a subscription basis.

The SaaS provider controls the structure, operating systems, middleware, and data needed to run the program, making sure that the software is available at anytime and anywhere customers need it.

Many SaaS applications run directly via web browsers, removing the need for downloads or installations. This cuts software management issues for internal IT teams and entry for companies to modernize their operations with mix and multi-cloud deployments. SaaS applications let companies set up and run fast while scaling their operations fast too. It is of no use buying or deploying the hardware and software utilized to deliver their business services. Examples of SaaS are Microsoft Office 365, Salesforce, Cisco WebEx, Google Apps.

Function-as-a-Service (FaaS)

Popularly known as serverless computing, FaaS lets customers carry out code reactively without having to distribute resources before time. The majority of FaaS applications are quite easy and can be deployed fast. Most FaaS services are available through significant cloud providers like AWS and Azure, which can end in vendor lock-in. Examples of FaaS: AWS Lambdas, Azure Functions.
