Know the Difference of ‘As-a-Service’ Cloud Solutions: IaaS vs. PaaS vs. SaaS vs. DMaaS

Know the Difference of ‘As-a-Service’ Cloud Solutions: IaaS vs. PaaS vs. SaaS vs. DMaaS

‘As-a-Service’ refers to cloud computing service that is provided by a third party so clients can focus on what’s more important to them, like coding or building relationships with customers. Each type of cloud computing leaves less and less on-premise infrastructure to manage. 

What is cloud computing? 

Before we further discuss the ‘As-a-Service’ cloud computing, you should know what cloud computing really means. 

Cloud computing is the delivery pile of computing resources over the Internet, including storage, processing power, databases, networking, analytics, artificial intelligence, and software applications. By outsourcing these resources, organisations can access computational assets they need, when they need them, without needing to purchase and maintain a physical, on-premise IT infrastructure. Therefore, cloud computing offers cost savings, scalability, high performance, economies of scale, and more. For many companies, cloud migration is directly related to data and IT modernisation. 

As-a-service business model 

IT computing has always involved a price tag for bigger, better, newer, faster, hardware and software to stay current for their data processing requirements. But initiated in 2021, the trend in IT spend has been moving in the direction of As-a-Service offerings. With As-a-Service models, the need for costly, protracted implementations shifted to subscription-based technology designed to reduce upfront IT spend. 

Over the years, the offerings become popular as the availability of an increasing inventory of As-a-Service offerings ensures that there is bound to be a service offering well matched to most client needs going forward. Cloud computing, on this matter, helps create the foundation for As-a-Service models. The IoT and edge computing gaining around the emergence of more service-based models is inevitable. 

As-a-Service models include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and Data Management as a Service (DMaaS) which provides health visibility and insight across hybrid environments. 


Infrastructure as a Service (IaaS) 

IaaS is a pay-as-you-go service where a third party provides infrastructure services, such as storage and virtualisation via the cloud through the Internet. As a user, you are responsible for the operating system and any data, applications, middleware, and runtimes. A provider will give you access to and management of the network, servers, virtualisation, and storage you need. 

Likewise, users do not need to maintain or update their on-site data centre because the provider does it. Instead, users access and control the infrastructure via an application programming interface (API) or dashboard. IaaS is a very affordable option for small-to-medium businesses as there is no maintenance cost and flexibility to purchase only components users need. Users can use only the infrastructure they need to create their development environment and scale it up or down. Then, they can stop when they are finished, paying only for what they use. 

Although IaaS is affordable and flexible, there are possibilities of provider security issues, multi-tenant systems where the provider must share infrastructure resources with multiple clients. Service reliability is also in question. These drawbacks can, however, be avoided by choosing a reliable and trustworthy provider with a solid history and reputation. 

Platform as a Service (PaaS) 

PaaS is where the provider hosts hardware and software on its own infrastructure and delivers a platform to users as an integrated solution, solution stack, or service through an Internet connection. PaaS is primarily useful for developers and programmers as it allows users to develop, run, and manage their own apps without having to build and maintain the infrastructure or platform associated with a process required to complete PaaS 

Developers can create a framework to build and customise their web-based applications with PaaS. They can also use built-in software components to create their applications which cuts down on the amount of code they have to write themselves. When developers write code, build, and manage their apps, they do not need to think about software updates or hardware maintenance as commonly, the environment to build and deploy is provided for developers by service providers. 

Software as a Service (SaaS) 

SaaS is also known as cloud application services, categorised as one of the most comprehensive forms of cloud computing services. SaaS helps deliver an entire application that is managed by a provider via a web browser. Software updates, bug fixes, and general software maintenance are handled by the provider just like in PaaS. Users only need to connect to the app via a dashboard or API. 

Compared to other cloud-based services, SaaS is a great option for small businesses that do not have staff or bandwidth to handle software installation and updates. SaaS is also suitable for businesses that do not require much customisation or will only be used periodically. Although SaaS is handy in its maintenance and time, the app could cost you control, security, and performance. Hence, it is important to find a SaaS provider you can trust. 

Data Management as a Service (DMaaS) 


GM of Intel Data Center Management Solutions Jeff Klaus wrote that DMaaS might become the future of integrated service of cloud computing choice. 

Comprising an integrated portfolio from software and hardware solutions, DMaaS enables optimisation of the Internet of Things layer by simplifying, monitoring, and servicing the data centre physical infrastructure of small to large enterprises. Klaus mentioned that DMaaS is a future solution as it promises real-time operational visibility, alarming and shortened resolution times without all the costs associated with deploying an on-premise data centre infrastructure management (DCIM) system.
