IaaS, PaaS and SaaS are cloud computing service models. Examples: Amazon EC2, Windows Azure, Rackspace, Google Compute Engine. Examples: AWS Elastic Beanstalk, Windows Azure, Heroku, Force.com, Google App Engine, Apache Stratos. While in SaaS (Software as a Service) model you are provided with access to application software often referred to as ...
4. VM's are IAAS (Infrastructure as a service) because on a VM you can manage what operation system runs and what software is installed. On a PAAS you only manage the software or application that runs in the cloud. (Like app services) answered Oct 5, 2020 at 15:16. Enrico.
5. Kubernetes is neither IaaS nor PaaS. It's a container orchestration engine which makes it more like a Container As A Service or CaaS. You need a IaaS layer below kubernetes to provide it VMs like for example AWS EC2 or bare metal servers. Kubernetes can be used as a platform for building Platform As a Service on top of it and CloudFoundry on ...
For example AppEngine managed VMS give you more freedom in choosing your underlying OS while still in a PaaS environment. And Google Autoscaler or Kubernetes brings managing your infrastructure to a more declarative level. Finally SaaS products are oriented towards non-technical end users.
A layer on top of IAAS (I nfrastructure A s A S ervice) Examples: Runtimes (like java runtimes), Databases (like mySql, Oracle), Web Servers (tomcat etc) SAAS (S oftware A s A S ervice) : A layer on top on PAAS. Examples: Applications like email (Gmail, Yahoo mail etc), Social Networking sites (Facebook etc) source.
3. Azure DevOps is SaaS for end users (Developers,PM,QA and other stakeholder). In the backend, all the services offer by "Azure DevOps" may run on VMs or Physical server. That mean Microsoft point of view, they may use combination of IaaS & PaaS solution for this platform. Ultimately all services running on VM or physical server.
2. In my mind Azure Storage is a PaaS solution (since you do not have to manage os updates, load balancing, performance allocation etc). You are provided with a rest api, and you act against that rest api. IaaS storage would be a storage inside virtual machine (s). Since you have to manage the VMs in order for that storage to work.
It is pretty clear that Amazon EC2 is IaaS. By contrast then Amazon Lighsail looks more PaaS. From the docs. Amazon Lightsail is the easiest way to get started with Amazon Web Services (AWS) for developers who need to build websites or web applications. It includes everything you need to launch your project quickly - instances (virtual private ...
Not a SaaS or an IaaS. A PaaS is a platform which allows you do build solutions on top of it. For example, service hosting, app hosting, storage, analytics etc. If you want to host services or apps, I can suggest the WSO2 Cloud. Not only hosting, it provides you a development platform as well. You can develops services and apps from scratch.
You can't build PaaS and SaaS without IaaS. So IaaS is must. A good example is Heroku which is a PaaS built on top of AWS IaaS. Whether a provider choose to expose underlying infrastructure as a service is a different matter all together. And this is what initially Microsoft did with Azure. Only after 2012, they formally got into IaaS. –
