Diff SAAS vs PAAS vs IAAS vs FAAS

  1. 1. SaaS: Software as a Service Software as a Service, also known as cloud application services, represents utilized option for businesses in the cloud market. SaaS utilizes the which are managed by a third-party vendor, to its users. A majority of through your web browser, which means they do not require any client side. SaaS is : •Managed from a central location •Hosted on a remote server •Accessible over the internet •Users not responsible for hardware or software updates
  2. 2. PaaS: Platform as a Service Cloud platform services, also known as Platform as a Service (PaaS), certain software while being used mainly for applications. PaaS delivers a that they can build upon and use to create customized applications. All networking can be managed by the enterprise or a third-party provider maintain management of the applications. •Simple, cost-effective development and deployment of apps •Scalable •Highly available •Developers can customize apps without the headache of maintaining the •Significant reduction in the amount of coding needed •Automation of business policy
  3. 3. IaaS: Infrastructure as a Service Cloud infrastructure services, known as Infrastructure as a Service (IaaS), scalable and automated compute resources. IaaS is fully self-service for computers, networking, storage, and other services. IaaS allows on-demand and as-needed instead of having to buy hardware outright. •The most flexible cloud computing model •Easy to automate deployment of storage, networking, servers, and •Hardware purchases can be based on consumption •Clients retain complete control of their infrastructure •Resources can be purchased as-needed •Highly scalable
  4. 4. FaaS: Function as a Service Function as a Service model facilitates a platform that allows customers to develop, run, and manage application functionalities without building and maintaining the infrastructure. AWS Lambda and Google Cloud Function are examples of the Function as a Service model. FaaS is an on-demand, pay-per-use service. Functions are triggered by a specific action or event taken on an application. Once that action is complete, it stops, so no background activity is being run. Examples are IBM Cloud Functions, AWS Lambda, and Google Cloud Functions. One downside is that the functions need to be stateless, which does not nature of the application deployed.
  5. 5. IaaS vs PaaS vs FaaS The type of cloud service largely depends on the levels of responsibility and control that you want to have over your IT infrastructure. If you want the benefits of the cloud, such as scalability, cost model, and disaster recovery, while maintaining a large degree of control, you should opt for the IaaS model. If you want your developers to enjoy the convenience of container orchestration as well, then CaaS is good for such IaaS situations. In case you do not want to deal with the complexity and nuance of setting up servers, networks, and databases, but you do have the time, budget, and resources to build your own software applications, including a skilled team of developers, then PaaS is the best choice. FaaS is suitable for very high-volume transactions, especially software with spikes in workload that need to be rapidly scaled as well as applications that are run on a dynamic basis or regularly scheduled.
  6. 6. Platform Type Common Examples SaaS Google Workspace, Dropbox, Salesforce, Cisco WebEx, Concur, GoToMeeting PaaS AWS Elastic Beanstalk, Windows Azure, Heroku, Force.com, Google App Engine, Apache Stratos, OpenShift IaaS DigitalOcean, Linode, Rackspace, Amazon Web Services (AWS), Cisco Metapod, Microsoft Azure, Google Compute Engine (GCE)
