Different Cloud Computing Service Models
Cloud computing is a relatively young industry, yet it made $272 billion in 2018. MarketsandMarkets estimated that it will grow even bigger at $623.3 billion by 2023. And all the thanks should be given to the different types of cloud computing service models.
Cloud computing deployment models helped the industry of cloud computing diversify. Cloud computing is now involved in a lot of other industries including smartphones, application development, online video streaming, social media, and more.
How, could cloud computing serve such a large number of industries? Read on to know the different functions of cloud computing service models.
Cloud Computing Service Models 1: Infrastructure as a Service
Infrastructure as a Service or IaaS is one of the main types of cloud computing service models. It is essentially a replacement for on-premise computing resources. These computing resources include data centers, networks, and servers.
Thus, it does everything that an on-premise platform could do. The main difference is that computing resources are offered through cloud in IaaS.
IaaS is preferred more nowadays than on-premise platforms. This is primarily due to its low cost and system flexibility. In IaaS, it is easier to upgrade computing resources.
In on-premise platforms, though, upgrades could be expensive and hard to put in. This is because all responsibility for on-premise platforms falls to the business itself. Responsibility includes hiring the manpower, hardware, and maintenance. Whereas, cloud computing service models such as IaaS are maintained by third-party providers.
Cloud Computing Service Models 2: Platform as a Service
Also, one of the major cloud computing service models is the Platform as a Service or PaaS.
In PaaS, a service provider delivers program development tools to businesses through cloud. These program development tools are used to design applications or any computer program.
Examples of platforms with a PaaS model are Windows Azure and Apache Stratos.
PaaS reduces cost of developing apps and software by availing resources from providers. It is also scalable as the service can downsize or upsize itself based on the size or budget of your business.
Developing tools in providers with a PaaS model are also usually more user-friendly. So, developing apps or software will be easier with cloud computing service models.
Cloud Computing Service Models 3: Software as a Service
Software as a Service is also among the three main types of cloud computing service models. This is always abbreviated as SaaS.
Among cloud computing service models, SaaS has one of the most developed markets. In fact, the global SaaS market is expected to get a market size of $185 billion by 2024 according to KBV Research.
Software as a Service platforms simply provides software through the Internet. Examples of platforms that use SaaS are Google Apps, MailChimp, DocuSign, and Hubspot.
These platforms cuts down the need to install apps in devices. This is because Software as a Service apps can be accessed using a browser.
Cloud Computing Service Models 4: Backend as a Service
The mobile industry has grown exponentially. It is now so large that another type was added among cloud computing service models.
Backend as a Service is an addition to the types of cloud computing service models. It is also abbreviated as BaaS. It is sometimes called Mobile Backend as a Service. This is because it mostly serve mobile device developers. This is also a relatively newer frontier among cloud computing service models.
BaaS platforms provide backend aspects for web or mobile programs. These backend aspects include database management, remote updating, push notifications, and user authentication.
Once BaaS is availed, all the developer has to do make now is the frontend. This frontend made up by the user interface and the client-side logic.
Cloud Computing Service Models 5: Serverless Computing
Another addition to the types of cloud computing models is the serverless computing. In this service model, the server itself is run by the service provider.
An essential aspect of this service model is the pricing. Users are only paying for what they actually used. So, uses are not required to pay for downtime since they haven’t used any service during such period.
Serverless computing does not completely cuts down the need for servers. It merely eliminates the need for the user to consider the the resources needed to execute tasks. This is because the servers are now maintained by the service provider.
Function as a Service also uses serverless computing. It is also abbreviated as FaaS. It is another minor addition to cloud computing service models.
FaaS allows users to develop apps and execute functions without maintaining infrastructure. This allows for a more efficient processing. This is one of the most radical cloud computing service models.
Other cloud computing service models are dependent on at least one server. In the FaaS platform, though, the server only runs when some functions failed. This cuts the time needed for handling server logistics.
Cloud computing is known for its malleable nature. This malleability also the reason behind the diversity of cloud computing deployment models.
