Many companies are struggling to keep up with the demands of providing fast, reliable, and secure services to their users. Indeed, growing pains are associated with increased power and storage capabilities for one’s IT infrastructure. There is, however, an option: instead of building out or expanding your infrastructure, your company can turn to cloud computing. Cloud computing providers offer solutions at affordable costs. Your company can save up to 30% by moving to the cloud.
Cloud computing comes in three main service models that address different business requirements. These are Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Platform as a Service (PaaS). They refer to the three ways to describe how you can utilize the cloud for your enterprise.
Software as a service
With this service model, the cloud provider offers and manages applications over the internet; your organization is relieved of the duty of managing its software, infrastructure, data availability, and security. Simply put, you don’t have to install and run applications on your workstations. The applications are web-based and can be accessed by logging into an account online via any device, as long as there is an internet connection. All your employees are provided personalized logins assigned with their privileges.
SaaS services are typically billed based on factors like the number of users, usage, storage capacity, and processed transactions. Usually, SaaS platforms charge users based on a subscription model, with a fixed recurring monthly fee. You know what to expect as to how much to pay, and there are no hidden charges.
Infrastructure as a service
Infrastructure as a service (IaaS) refers to resources such as networks, storage facilities, virtual private servers, and processing power acquired on-demand over the internet. Users are charged on a pay-as-you-go model, billed based on their consumption over a time period.
IaaS provides businesses with cloud-based alternatives, keeping them from shelling out money on costly onsite resources. The maintenance of on-premise IT infrastructure could dent a company’s budget, apart from being labor-intensive. That’s because on-premise IT infrastructure requires a massive investment in physical hardware. In addition to this, a company would need to tap external IT contractors to keep the hardware in tip-top shape.
When it comes to IaaS, you no longer have to invest in expensive hardware. You only need to purchase what you need when you need it and scale your resources as your business expands. Besides, you have control over your infrastructure and have the choice to oversee your IaaS platforms. IaaS platform providers offer ongoing support as well.
Platform as a service
A Platform as a Service (PaaS) vendor offers infrastructure and software services over the internet. Often, the target users take advantage of PaaS services to build applications. The market for this service usually comprises developers.
By using PaaS, developers don’t need to start from scratch when building applications, saving time and money. Businesses often opt for this type of service as they don’t have to invest much money and effort in creating unique applications.
PaaS platforms are accessible to several users; are customizable; utilize virtualization capabilities, and run seamlessly. Examples of PaaS include AWS Elastic Beanstalk, Google App Engine, OpenShift, Windows Azure, and Heroku.
