This article introduces the knowledge of "what is the laaS, PaaS and SaaS of cloud computing". Many people will encounter this dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!
Looking at IaaS, PaaS and SaaS with examples
Take dumplings as an example, at this time you need to prepare the flour, chop the stuffing, mix the ingredients you need, and wait for the flour to be fermented and mixed. At the same time, we should also prepare kitchen utensils such as gas, steamer and chopping board, as well as our own table and cutlery. Put the dumplings in the steamer and steam them before you can enjoy them.
Everything is prepared by yourself, so this is called On-Premises.
Of course, if you find it troublesome, you can go directly to the supermarket to buy frozen dumplings made by others, and cook them directly at home. At this time, you only need to prepare pots and gas stoves, as well as tables and kitchen utensils.
Instead of doing it in your own home, you need a dumpling supplier, which is Infrastructure as a Service (IaaS).
But if you still feel a little troublesome, you can call a dumpling restaurant and ask a restaurant to deliver the hot dumplings directly. You just need to prepare the table. This is called platform as a Service (PaaS).
If you don't want to prepare anything, or even don't even bother to tidy up the table, go straight to the dumpling shop. Everything is ready there. This is Software and Services (SaaS).
To sum up, there are four ways to eat dumplings, either get all the ingredients ready and cook them at home, buy ready-made ones and cook them, order takeout, or go to the restaurant.
Three Service modes of Cloud Computing
Suppose there is such a top-notch company that does not need others to provide services at all. It has its own infrastructure, applications, and so on. They can be divided into three layers: infrastructure, platform and software.
The infrastructure mainly includes network system (networking), storage device (storage), server (servers) and virtualization technology (virtualization). The platform is on top of the infrastructure, including the operating system (OS), middleware (middleware) and runtime (runtime). Then the software adds data (date) and application (application) on the basis of the platform.
These are actually the three layers of cloud computing, with the basic handout at the absolute end, the platform in the middle, and the software at the top, namely Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS), while some other "layers" can continue to be added on top of them.
The company now has everything, so it is in a state of On-Premises. If you want to run enterprise applications on the company's website, you need to buy servers, which have other expensive devices to control local applications to ensure that the business works.
If one day, the boss of this company thinks that he is just eating dumplings and that it is necessary to buy both a stove and a steamer, why should he make it himself? So at this time, you are ready to look for a cloud service provider, so what services does this provider need?
The main cloud services are the three tiers of cloud computing, IaaS, PaaS and SaaS, just like the three services offered by dumpling shops: packing, takeout and eating inside.
Generally speaking, IaaS, PaaS and SaaS are the three levels of cloud service provision. the basic one is IaaS, the middle one is PaaS, and the last one is SaaS.
That's all for "what are the laaS, PaaS and SaaS of Cloud Computing?" Thank you for reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
