SaaS, IaaS, and PaaS- Cloud Computing Architecture Explained

For the non-technical professionals, cloud, cloud compute concepts, and their working something cryptic, which is also why executing cloud operations becomes a tough nut to crack for specific organizations. Also, the other reason why organizations skip cloud computing is the utilization of digital services and apps by the cloud by the consumers. But, once the IT professionals are aware of the cloud architectures and the benefits, they provide in having the upper hand in the industry, implementing cloud services becomes necessary.

SaaS or Software as a Service

The SaaS architecture of the cloud is responsible for handling server uptime, technical processes, and security. This type of solution delivers the client with suites for launching and using the projects and apps on the go. The involvement of the technical department is almost zero as the entire SaaS infrastructure is taken care of by the public cloud service provider.

Because it is based on the web delivery model, the need to run or install applications on the device does not exist. It becomes a facile task to handle support and maintenance because the provider takes care of the data, runtime, applications, servers, networking, and storage.

Key pointers of SaaS

Do not have to worry about installation or upgrade of the software

Failure of equipment does affect the data

Use of resources that are scalable as per the needs of the business

SaaS cloud architecture is ideal for startups and organizations looking to deploy their applications or websites swiftly. The most sought-after services of SaaS are customer relationship management and email and collaboration.

Examples of SaaS

Mailchimp

Microsoft Office 365

Google G Suite

Benefits of SaaS

SaaS provides a wide range of services that can be used to deploy web-based software applications.

This architecture can be accessed easily through a browser.

PaaS or Platform as a Service

PaaS as an architecture provides flexibility and client-server space along with the services and tools which can be customized and help the clients to develop the required applications efficiently and quickly. The service providers of PaaS offer you additional benefits like operating system, middleware, runtime, and storage, irrespective of whether the client can manage the existing data.

Platform as a Service combines software and infrastructure required for software applications. Some of the benefits of PaaS are inclusive reduction in coding, migration of applications, and automation of the policies.

Key Pointers of PaaS

You get the tools for hosting and application development on the same platform.

The service provider handles the operating system, security, and server backup.

Automation of business policies and reduction in the amount of coding

PaaS architecture is the best fit for developers looking for flexibility in the development of applications from the start without having to worry about runtime or traffic load management.

Examples of PaaS

Out Systems

Heroku

Google App Engine

Benefits of PaaS

The programmers do not have to worry about the specific language or database in which the application has been programmed.

This architecture allows the developers to build applications without adding an underlying infrastructure or operating system.

IaaS or Infrastructure as a Service

Infrastructure as a Service is all about the managed services or the cloud services that use specified network infrastructure or cloud-based servers. The organizations rent or buy the server space and build their operations without the vendor's intervention.

With IaaS, you have complete control of infrastructure management in the public cloud, but it requires expertise and resources for configuration and management. In the case of IaaS, the service provider handles the hardware and OS of the infrastructure, and one of the critical advantages of this service is a scalable environment.

Key pointers of IaaS

Accommodation of operational and business needs with a scalable environment

Complete control over the infrastructure

You can get IaaS on-demand, and instead of hardware, you can purchase this

This type of infrastructure is well-suited for companies with skilled developers with the expertise to build applications and digital solutions from scratch. And, if the technical department can manage the traffic loads, IaaS provides complete infrastructure control.

Examples of IaaS

Google Cloud Compute Engine

Microsoft Azure

Amazon Web Services

Benefits of IaaS

The deployment of resources is possible at any given time from the service provider to the customers’ environment.

It offers the ability to the clients to scale their businesses as per the requirements.

Wrapping Up
