This is what the engineers say about the stack, the IaaS, PaaS, SaaS three tiers we hear. The IaaS layer is like a PC's base hardware plus driver, and the
Problem one: On the basis of virtualization construction, the choice of three private cloud construction direction is discussed.
As we all know, virtualization and cloud computing are different, when the scale and day of virtualization increase, to the urgency of automation, standardization, process and service quality requirements to a certain extent, we will choose to carry out enterprise private cloud construction.
But private cloud construction currently has a roughly three-way direction:

Although Google App Engine has won the leading position in the cloud computing PAAs field in the last one or two years, after a long time of learning and practicing Google App Engine, it is found that there are many shortcomings in its existing implementation, and these flaws may become its "Achilles Heel". Next we will analyze in detail what problems the App Engine has.App Engine Deficiency

Advantages and disadvantages of microservice ArchitectureAbstract: This article is from the official Nginx blog and is the first article in The microservice series. It mainly discusses the shortcomings of traditional monolithic applications and the advantages and challenges of the microservice architecture. As the author said, microservice architecture is more suitable for building complex applications, although it also has its own shortcomings.

Python pseudo-Developer's assessment of Sohu Cloud ViewI am a fan of Gae and OpenShift and have played various foreign PAAs. A Python web program that wants to get a little more complicated, needs a better network transfer speed, and tries to find the pre-PM (Project Manager) to play a domestic VPS. The former PM said that recently engaged in a Sohu Cloud view Beta activation code, let me try first, so I have my first strange python application in SCE
If you're an OPS engineer, you know that Docker is valued at more than $1 billion, and Docker is one of the most popular technology brands. Docker containers are known as the de facto standard for container runtimes, but Google's kubernetes is winning the choreography framework market. When using container technology, we often encounter the question, "will using Kubernetes hurt Docker?" ”Many people believe that the value of container technology is at the orchestration level, which is a direct t

Of course, this product is only available in PAAs for use in azure. Documentdb started previewing last fall, this

The system will automatically select the appropriate working node to perform the specific container cluster scheduling processing work. The core concept is the container Pod (container compartment).
