Part 2 | Your FORTE CLOUD Journey: Cloud Computing Types and How to Choose?

In the first article of our cloud journey series, we talked about what cloud computing is and the different deployment models, also their advantages. In the second part, we will talk about several types of cloud computing and their uses and advantages.

Each type of cloud computing offers you various levels of control, flexibility, a1nd management. As such, you must understand each type and its uses before migrating to the cloud. With this knowledge, you can choose the type that is best suited to your business needs.

There are three types of cloud computing:

    • Infrastructure as a service (IaaS)
    • Platform as a service (PaaS)
    • Software as a service (SaaS)

Infrastructure as a Service (IaaS)

Infrastructure as a service or IaaS is the most common first step for businesses migrating to the cloud. It is the basic building block for cloud IT. As it allows businesses to purchase computer hardware, storage devices, and networking services from a third party and deploy virtual machines (VMs) which they can then manage. IaaS is the most like on-premises, however without the hassle of owning or managing the physical environment.

Examples:

    • AWS (Amazon Web Services) EC2 Instance
    • Google Cloud VM Instance
    • Azure Virtual Machine

Advantages:

    • Their pay-as-you-go model makes it cost-effective as you only pay for what you use
    • Complete control over the infrastructure
    • Easy to scale down or up
    • No physical hardware to maintain or manage

Disadvantages:

    • Ensuring that everything is working properly and providing the utmost security
    • The data is your responsibility, if it’s lost, it’s your job to get it back
    • Of the three types, it is the most hands-on type. IaaS providers only provide the servers and their API, anything else is your responsibility

Platform as a Service (PaaS)

Platform as a service (PaaS) enables you to create environments on-demand to build custom applications for developing, testing, delivering, and managing software and services. And with PaaS, you no longer have to worry about dealing with data serving, storage, and management. It removes the need for organizations to manage the underlying infrastructure (usually hardware and operating systems). This will allow you to focus on the deployment and management of your applications.

Examples:

    • AWS Elastic Beanstalk
    • Google App Engine
    • Microsoft Azure Web Apps
    • Google Cloud SQL

Advantages:

    • Easy to use
    • Collaboration between developers is easy
    • Easy to customize and update apps without worrying about software upkeep on the backend
    • Flexibility and scalability as the application continues to grow

Disadvantages:

    • Limited control as you can only manage the code of the app and not the infrastructure behind it
    • Data is stored by the PaaS organization, depending on the provider you’re using, it could be a security risk
    • Platform customization on your end is limited by the PaaS organization’s terms of service

Software as a Service (SaaS)

Software as a Service or SaaS provides businesses with access to ready-to-use software like email, word processing, design software, and a whole host of other applications. It’s accessible through a web browser, removing the need for your team to install applications entirely. With it, you do not have to maintain the services or manage the underlying infrastructure, as all of it is the provider’s responsibility. You just have to focus all your time and energy on getting the best use out of this software.

Examples:

    • Microsoft Office365
    • Google Guite
    • Salesforce
    • Slack
    • DocuSign
    • MailChimp
    • Dropbox

Advantages:

    • No need to worry about the software’s upkeep or management and upgrades
    • Doesn’t consume any of your local resources
    • Easy to find and set up

Disadvantages:

    • No control over the infrastructure, if there’s an outage from the provider’s side, it will affect you too
    • May cause issues with other tools and hardware you’re already using
    • You can’t patch an integration from your end, it must be offered by the provider
    • If the SaaS’s security is compromised, your data’s security is also compromised
