What is IaaS, PaaS, SaaS?
Look at the following icon:
We can understand this as:
Iaas:infrastructure-as-a-service (infrastructure as service)
Paas:platform-as-a-service (Platform as service)
Saas:software-as-a-service (software as a service)
The first layer is called IaaS, sometimes called Hardware-as-a-service, and a few years ago if you wanted to run some enterprise apps on your office or company web site, you needed to buy a server, or other e
Previously, the MySQL PAAs database was created in Azure, and now you want to stop the azure MySQL PAAs database because the test system is offline. But the long time found on the Azure portal did not find that the stop option could be like those of a virtual machine, only deleted. learned that MySQL database once created is not able to stop. You can export the database locally through mysqldump and then de

Two weeks ago, after CentOS announced its participation in RedHat, OpenShift, A PaaS product of RedHat, officially announced its support for CentOS. OpenShift indicates that running OpenShift in CentOS is slightly different: First, we provide some new packages for avahi-based MDNS multicast support; secondly, ensure that all packages compiled under EL6 are not dependent on CentOS, and perform a complete test. OpenSh

Let's take a look at the last picture.Cloud computing has SPI, the three service models of SaaS, PAAs and IaaS. PAAs and IaaS originate from SaaSSaasSoftware as a services software as a service, the service provided to the customer is the applicationPaasPlatform as a services platform as a service, providing customers with services is the software development platform, that is, customers can deploy their ow
The biggest difference is one is paas, another is IAAs,
For example: You can specify the instance number of load balance just by simploy setting the number in the configuration of VM role.
So, that is the PAAs adventages. but I thought it is part of paas, because as MS announced, user shocould be reponsable for the system updating of VM image. I think it shosho
patches, resulting in increasing technical debt. If the software version used does not provide maintenance, it can only be implemented by a specific person or team or the whole application rewrite method. This is very common in actual application development, large companies such as Microsoft cannot avoid this problem, which will lead to related risks.
In the above section, we analyze the advantages and problems of the monolithic architecture based on the problems encountered in actual applic

In the previous chapter, I described how we can use the web role and worker role of Azure PAAs to handle complex business logic-web role can quickly respond to front-end business requests and save input to the Azure Storage queue-worker role reads data from the queue and can handle complex business logic on the backend-As you can

Without cloud services, you need to invest in a server, install Server software, and write Web programs.Now you're following the trend, using popular cloud computing,If you're using IaaS services, it means you don't have to buy your own servers and buy virtual machines anywhere, but you still need to install your own server software.And if you use PAAs services, it means that you do not need to buy a se

Recently done several projects, the platform is becoming more and more serious, even the end of the direct and platform interaction, may be the front end is only the skin and layout is their own, even the skin is unification.
Then we associate it with the concept of SaaS.
Server-side call platform is actually a SaaS, but it's not thorough enough.
Bicycle unified cashier, in order to avoid brand exposure, the interface to do their own, but also a kind of SaaS, as long as the request sign signa
