The editor will share with you the types of services mentioned in the AWS certification exam. I hope you will gain something after reading this article. Let's discuss it together.

Several types of services may be examined in the AWS certification exam.

The distinction according to the level of management of the service is as follows:

On-Premises-IaaS-PaaS-SaaS

On-Premises

Is the traditional software server architecture.

You will manage all types of services, including the Internet.

IaaS

As opposed to On-Premises, let other service providers manage the network and infrastructure. This type is usually similar to what we call server hosting.

You can host your server in some IDC centers, and IDC will manage many basic services such as network, server, virtualization and so on. You need to install the operating system and middleware on the basis of the above.

This middleware is the same concept as what we call an application server, or a front-end server.

PaaS

Compared with IaaS, the degree of management is higher.

You only need to manage your application services and data, and other services, including the operating system, will be managed and deployed by other companies such as AWS.

You are only responsible for your data and applications. Relatively speaking, this approach allows users to focus more on the application process without having to care too much about the server and services.

SaaS

All services are hosted by third-party platforms.

In this development model, users usually only need to pay attention to their own business process development, all the relevant data are not in the company's internal, are on the third-party platform.

Knowledge point

For the above hosting platform and way, in fact, it is based on the number of third-party hosting platform to distinguish.

In the current architecture, many companies may use a service called a hybrid architecture.

Hybrid architecture means that the company still retains some of the servers, but puts some services on the cloud platform.

For example, if you are now running a community forum, your users also like your forum very much, uploading hundreds of MB attachments and pictures every day.

Before there is no cloud service and hybrid architecture design, all your images will be deleted on your server and backed up when necessary, and as there is more and more data, the size of the backup files will become larger and longer. At this time, you can consider adopting a hybrid architecture design, because the pictures uploaded in the community are open, of course, you can choose not to open up. So you can upload images to AWS's S3 storage and use CloudFront as a CDN network to increase image loading speed and reduce the load on your server.

In many design structures, this kind of similar design is now used more and more.
