A network engineer is responsible for tracking the vulnerability information of firewalls and routers. After a patch is dete

1. Keep in mind the basics Don't forget every basic step in the migration process. Although the migration process has to stop, but when the original server is still in, to do as much as possible, as frequently as possible load test. Also, remember to modify domain DNS and, in general, set the TTL as low as possible. It is a good practice to do a test that 3~4 times the new DNS run plan before migrating. 2. Know your App Based on past experience, you need to understand the architecture of your

Openstack compute (NOVA) Function Analysis Openstack compute provides a cloud tool for an organization. Its functions include running Virtual Machine instances,Manage networks and control cloud access through users and projects. The most basic open-source project of openstack is named Nova. It provides software that can control the infrastructure as a service (IAAS) cloud computing platform, and AmazonEC2 and rackspace ECs are similar

Openstack Object Storage (SWIFT) is one of the sub-projects of openstack's open-source cloud computing project. Swift uses common servers to build reliable and Scalable Distributed Object Storage clusters with a storage capacity of hundreds of petabytes or even exabytes. Swift, formerly known as the

The former is the virtual server deployment and business computing module developed by NASA, and the latter is the distributed cloud storage module developed by Rackspack, which can be used together, it can also be used separately.

What does IaaS mean?Iaas:infrastructure-as-a-service (infrastructure as a service)The first layer is called IaaS, sometimes called Hardware-as-a-service.A few years ago if you want to run some business applications in your office or on your company's website, you need to buy servers or other high-level hardware to control your local applications and get your business up and running.But now with IaaS, you can outsource your hardware to other places. IaaS will provide off-site

To get a better understanding, let's start with the type of cloud computing. Depending on the type of service provided, cloud computing has the following three landing methods:1. Iaas (infrastructure as a service) from which users can request hardware or virtual hardware, including bare metal or virtual machines, and then install the operating system or other applications on top.2, PaaS (Platform-as-a-service), the user can apply to a installation of the operating system and support the applicat
