technologies (such as virtualization) with clever methods to provide IT services on the pipeline, resulting in economies of scale. Next we will discuss in more detail what are the core technologies and what are the key features of these technologies in cloud computing applications.Core cloud computing technologyCloud

to external)? A:1. Container, container 2. External service->nginx-> container 3. Container->nginx-> container 4. External services, containers. This is the case, mainly looking at the business scenario. Q: What CI tools are used to build a service cluster, or do you develop it yourself? What is the role of ETCD? A: Self-developed, ETCD equivalent to Message Queuing, the control layer received a build request, ETCD in the current cluster under which the build machine, when t

through the network and supports various standard access methods, including various thin or fat client platforms such as mobile phones, laptops, and PDAs ), it also includes other traditional or cloud-based services.? Virtualized resource "pool": the provider's computing resources are pooled into the resource pool. The multi-tenant model is used to meet user needs, dynamically allocate or distribute differ

platform to run your software is provided by me to ensure that your software runs. Popular SAE What kind of, you take (the world's best programming language) PHP to write a website, upload to me, I will give you the site to run up. You concentrate on writing (copying) your software and giving it to me.IaaS sells virtual machines. I will give you a virtual machine, to ensure that they run normally, can connect the net. Virtual machines How do you use whatever you want. Representative of AWS, Azu

, but also a political issue. Service heterogeneity. Due to the heterogeneous nature, it is difficult for applications and data to be migrated between cloud providers. suppliers may be locked, which brings great risks to cloud computing users. In addition, the three layers of cloud

3. Cloud computing hierarchy We start with the lowest level of service, that is, infrastructure (Infrastructure-as-a-ServiceOr IaaS ). IaaS is leasing infrastructure (computing resources and storage) as a service. This means that the virtual computer not only has a guaranteed processing capability, but alsoBandwidth is reserved for Internet access. In fact, IaaS

flexibility to solve multiple small problems. In this way, grid computing provides a multi-user environment. Its second goal is to make better use of available computing power to cater to the intermittent needs of large-scale computing exercises. With grid computing technology, you can combine servers, storage syst

be turned off. Cloud computing goes further, providing computing resources as needed. In this way, we can avoid excessive supply when using public pricing. This eliminates the need for over-supply when meeting the needs of millions of users. Infrastructure as a service Consumers can obtain services from a complete computer infrastructure through the Internet.

For cloud computing, 2016 was a connecting year, the 10 anniversary of the launch of the AWS Amazon Cloud and the 10 anniversary of Google's first mention of cloud computing. Over the past 10 years, cloud

directly manipulate underlying resources. However, the advantage is that you can purchase the required resources as needed without spending any unnecessary money. In addition, when the business grows to require more resources, you can spend money to purchase it, and the application itself does not need to be deprecated, and the user does not need to maintain it. The third is that IAAs is both infrastructure as a service. Amazon ec2. It provides a complete virtual machine environment, including
