The emergence of cloud computing in recent years certainly revolutionized the way enterprises manage large-scale applications and derive value from data. It is rather a big shift from the traditional way businesses think of IT resources and enable users to use multiple apps, helping them solve workload challenges quickly and precisely from anywhere through any device, naturally reducing computing costs. In fact, the tech enthusiasts are now exploiting cloud computing for cybersecurity protocols as well, such as we now have cloud VPN for Windows 10 and other latest machines.
Types Of Cloud Computing
Cloud computing can generally be broken down into three most common and widely adopted branches, each with its own advantages:
Infrastructure as a service (IaaS):
It is the most vital category of cloud computing services allowing the enterprises to use the unlimited storage potential of the cloud infrastructure. Users can expand and shrink their storage space as needed, scales up and down with demand making you pay only for what you use. It helps you avoid the expense and complexity of buying and managing your own physical servers without having to worry about dedicated servers on site and other datacentre infrastructure.
Some of the key players offering IaaS are Microsoft Azure, Rackspace, DigitalOcean, Google Cloud Platform, Amazon EC2, GoGrid, among others.
Benefits of IaaS:
- Reduce cost
- Website hosting
- Internal networking
- Better security
- Bring new apps to users faster
- Increased reliability, stability, and compatibility
- Improves business continuity
Platform as a service (PaaS):
PaaS service refers to supply an on-demand environment for establishing, testing, delivering, and managing software applications. It lets you avoid the investment and intricacy of buying and managing software licenses, the hidden application framework, and middleware or the development tools and other resources. Businesses using PaaS can expand their applications onto different platforms and use them seamlessly.
Some of the key players offering PaaS are Salesforce.com, AWS, Microsoft Azure, Google App Engine, Bluemix, CloudBees, Heroku, OpenShift, Oracle Cloud, OpenShift and SAP.
Benefits of PaaS:
- Improve speed, flexibility, and agility
- Reduced coding time
- Use sophisticated gadgets affordably
- Effectively manage the application lifecycle
- More development capabilities with less staff
Software as a Service (SaaS):
SaaS enables users to connect to and use cloud-based apps over the Internet. It is a complete software solution one can purchase on a pay-as-you-go basis from a cloud service provider. It is relatively mature as it incorporates both IaaS and PaaS.
With the assistance of SaaS, cloud providers manage and host the software application and hidden infrastructure, and tackle maintenance, like software upgrades and security damage. The software is easily accessible via the Internet from any device, at any time, from any location, even though the application is hosted at a central location. Payment for the use of these apps is made by subscription or according to the level of use.
Some examples of SaaS are Google G Suite, Microsoft Office 360, AppDynamics, Adobe Creative Cloud, Zoho, Salesforce, Marketo, Oracle CRM, SAP Business ByDesign, and Pardot Marketing Automation.
Benefits of PaaS:
- Gain access to sophisticated enterprise applications
- Only pay for what you use
- Global access to the app data
- Mobilize workforce easily
- Free client software is used
