Right Cloud Service Model For Your Business
Sooner or later, every business computing will be through cloud platforms. Cloud computing offers ready-to-deploy on-demand highly powerful virtual tools, ranging from pure computational power to application functionalities. The plug-n-play nature of the cloud services brings agility and flexible choice to scale-up or scale-down your computational capabilities, storage, and network resources depending on the requirement without any hassles. The same in a traditional set-up would require you to invest and install physical servers, network equipment, and real estate. Cloud computing takes out the rigidity involved with infrastructural computing.
Global cloud service adoption has grown staggeringly over the years. The rising number of cloud service providers such as Amazon Web Services (AWS), Salesforce’s CRM system, Microsoft Azure, and Google Cloud is proof that every major tech-giant company wants a piece of cloud computing trend.
Both the public and private enterprises are switching to cloud computing due to the benefits of cost and on-demand scaling and scale-down capabilities. For example, application development in cloud computing provides a comprehensive, agile, and cost-effective way to implement cloud service models. Cloud computing takes out the hassles involved in enterprise business computing.
Companies do not have to worry about the infrastructural investment and maintenance required for their application and services to run. They can now focus better on the quality of their services and solutions, which is the core of their business.
Benefits of Cloud Computing
The reduced time to market and the ability to dynamically scale is of the main reasons businesses are choosing cloud computing. More often, developers are choosing cloud service for application development due to an immense number of advanced tools and new services that they can incorporate as part of the functionalities of their applications.
Following are some of the main advantages of cloud computing:
Dynamic Scaling - You can quickly scale down or scale up your computing resources based on your changing load and needs.
Low cost - Cloud computing eliminates the need for expensive servers and data centers, and you only a margin of the lifetime cost of infrastructural investments.
Secure - Your business data is more secure in a cloud server than it is in your local server. Cloud services use industrial-grade security protocols, so when you sign up for a cloud service, you are making your data more safe and secure.
What are the Different Cloud Service Models?
There are four types of cloud models, with each offering a set of benefits over the other:
SaaS (software as a service)
SaaS model delivers applications over the internet that you can access through your browser. Google's Gsuite and Microsoft Office 365 are two of the most popular SaaS business applications. Almost every enterprise application has migrated to the SaaS model. SaaS applications provide a great deal of customization and configuration options that enables businesses to code and modify the functionalities more suited for their business.
IaaS (infrastructure as a service)
IaaS or infrastructure as a service is a per-per-use model. It offers highly sophisticated large scale enterprise application services that range from machine learning, application monitoring, VPNs, big data analytics, developer tools, and many more. AWS (Amazon Web Services) is the top IaaS service provider with IBM Cloud, Microsoft Azure, and Google cloud closely following.
PaaS (Platform as a service)
PaaS is a developer-oriented cloud model where developers can access tools, processes, APIs for software development, testing, and deployment workflows. To a great extent, PaaS simplifies the challenges of enterprise software development. Google App Engine, Salesforce's Heroku are two of the highly sought after PaaS cloud providers.
FaaS (function as a service)
FaaS model is another layer of abstraction over PaaS, this creates an impermeable layer between the developers' code and the underlying stack. Almost all cloud service providers offer FaaS over IaaS, the main advantage of FaaS is that it does not consume an IaaS resource until a certain event such as submission of a form or a file upload, etc. reducing the pay-per fees.
Why Choose SaaS?
In the SaaS model, the user has no control over the hardware and can only make changes to the software service they use. SaaS is ideal for small businesses that do not have the budget for an in-house server and data center. For example, Shopify is an example of an affordable eCommerce platform for small-business who can not afford their eCommerce platform running on in-house servers and data centers.
Why Choose IaaS?
IaaS is the perfect choice for enterprise applications where you require to scale up and scale down hardware as well based on your organizational needs. IaaS is an optimal choice for startups as well as big enterprises where they can have access to hardware infrastructure without investing in them separately. IaaS cloud model is more expensive than SaaS and PaaS.
Why Choose PaaS?
Paas is an ideal choice if there are multiple stakeholders and developers involved in your project. PaaS aims to simplify software development by improving the development speed and speed to market. Businesses can create customized applications without investing separately in computational and networking tools and resources.
Why choose FaaS?
Faas is preferable if you need you to need event requests to be automatically detected and handled instantly. In the case of no event requests, the entire application can be shut down. FaaS helps you save cost as you only pay for what you use and if no usage, then no cost.
Cloud service providers are continuously improving cloud computing capabilities and services. Businesses have more reasons than ever to switch to cloud platforms for their business applications and operation.
