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 expensive hardware to control your local apps

OpenStack is a cloud computing software developed by NASA and Rackspace, which is licensed by Apache License and is a free software and open source project. OpenStack is the IaaS (infrastructure, service) software that allows anyone to build and provide cloud computing services on their own. In addition, OpenStack is also used to create a "private cloud" within a firewall (private Cloud) that provides the resources shared by organizations or departmen

It restricts work at the puppet Lab's business development department, where he studies technology and thinks about how to deliver value through integrated puppet. The Puppet Lab's IT automation software enables system administrators to achieve cloud computing enterprise-level agility and efficiency, from hundreds of nodes to tens of thousands of nodes. Puppet is being used in thousands of companies includi

-DDoS attack solution used in this test was Cisco's acquisition and integration of products called Riverhead, which made a very important innovation in dealing with DDoS, and presented the concept of "guidance" and the two key defenses against DDoS attacks: anti-deception defense lines and statistical analysis lines. The system is composed of intelligent DDoS protection system detector detector and protective device guard. In foreign telecom operators, portals, online gaming companies and onlin

amounts of memory and CPU resources. Docker is very lightweight compared to it. It works just like a regular program. This container is not only running fast, it is also very quick to create a mirror and make a file system snapshot. It can be run in a virtual environment like EC2, RackSpace VMs. In fact, a better way to use Docker on MAC and Windows systems is to use vagrant. Docker's original intention was to play a VM-like role, but it started fast

server. You only need to install Ansible on one server, and after the Ansible is installed, you can manage to control other servers. You do not need to configure the database for it, Ansible does not start or remain running in daemons manner. Ansible's objectives are as follows: Automating deployment of applications Automated Management configuration Continuous delivery of automation Automated (AWS) cloud service management. According to Ansible's official informatio

Label:NoSQL(NoSQL = Not Only SQL )，意即"不仅仅是SQL"。 On modern computing systems, a huge amount of data is generated every day on the network. A significant portion of this data is handled by the relational database management system (RDMBSS). The 1970 E.f.codd's paper "A Relational model of data for large shared data banks", which makes data modeling and application programming easier.The application proves that the relational model is well suited to client server programming, far exceeding the exp

this setting keeps bothering you, then there is a problem with your design pattern, or you can use a file with no size limit Gridfs. The usual recommendation in this case is to avoid storing too large files, and occasionally updating various objects stored in the database. Services such as Amazon S3 or Rackspace CloudFiles can often be a better choice, and it's better not to overload the infrastructure without the need. Summary: Keep each file below

management tasks and reconfigure the machine through foreman. Foreman can manage large-scale (and of course small-scale), enterprise-class networks, possibly with many domains, subnets, and many puppet master nodes. Foreman can also implement the backtracking of the configuration version. foreman can run on almost all popular Linux systems, such as: rhel/centos/fedora/oracle Enterprise linux/scientific linux/der Linux operating system suse/opensuse debian/ubuntu
