SNA's connection based architecture invoked huge state machine logic to keep track of everything. APPN added a new dimension to state logic with its concept of differing node types. While it was solid when everything was running correctly, there was still a need for manual intervention.
A deployment diagram [1] "specifies constructs that can be used to define the execution architecture of systems and the assignment of software artifacts to system elements." [1] To describe a web site, for example, a deployment diagram would show what hardware components ("nodes") exist (e.g., a web server, an application server, and a database server), what software components ("artifacts ...
LVS-based solutions already have been deployed in many real applications throughout the world, including Wikipedia. The LVS components depend upon the Linux Netfilter framework, and its source code is available in the net/netfilter/ipvs subdirectory within the Linux kernel source. LVS is able to handle UDP, TCP layer-4 protocols as well as FTP ...
Sysrepo is a YANG-based configuration and operational datastore for Unix/Linux applications. yangbuilder is a builder for YANG, implemented in Apache Groovy (generate yang data models with Apache Groovy , maintain similar models with one source code base)
It is not related to the Linux Virtual Server project, which implements network load balancing. Linux-VServer is a jail mechanism in that it can be used to securely partition resources on a computer system (such as the file system, CPU time, network addresses and memory) in such a way that processes cannot mount a denial-of-service attack on ...
Node management LIF interface can migrate with associated IP address across Ethernet ports of a single node and available only while ONTAP running on the node, usually located on e0M port of the node; Node management IP sometimes used by cluster admin to communicate with a node to cluster shell in rare cases where commands have to be issued ...
The Linux kernel provides the cgroups functionality that allows limitation and prioritization of resources (CPU, memory, block I/O, network, etc.) without the need for starting any virtual machines, and also the namespace isolation functionality that allows complete isolation of an application's view of the operating environment, including ...
A Node is a compute instance (a blade, hypervisor, or VM) where service instances (workload) are deployed. The set of nodes belonging to the same communication subnet (no routing) comprise the logical Cluster. Every node in the cluster must run an execution environment for services, as well as OpenSAF services listed below:
