If necessary, the user should isolate the worm or virus from the network segment and then start the repair process. Mr. Engates, CTO of Rackspace, believes that vrouters and firewalls are very similar to the version of the upgraded software. A network engineer is responsible for tracking the vulnerability information of firewalls and routers. After a patch is dete

Recently, when looking for a job, I was asked some principles of Swift's bottom, so I decided to take notes in order to be able to impress.

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
