Persistent Cloud Services (PCS) @ HP NONSTOP

An implementation of techniques and software which extends the inherent linear scalability of NonStop systems to a multi-platform environment consisting of NonStop servers as well as commodity Linux/Unix/Windows (LUW) servers.

§NonStop in the Cloud

§NonStop as the Cloud

§Cloud In The Box

§Converged Infrastructure

§Peak Capacity versus Elastic Metering

The primary software components of PCS are: TS/MP 2.4 (aka PATHWAY/PATHMON) TS/MP (Transaction Services / Massively Parallel), aka PATHWAY, is a middleware product for the HP NonStop and provides transaction services, monitoring and management.

1. Application Clustering Services (ACS) ACS works in conjunction with PATHWAY-TS/MP to control communications between requestor and server processes
2. Gateway Server C program provided by HP Consulting Services which runs under PATHWAY to enable PCS functionality
3. Persistent Cloud Services (PCS) library routines Java jar (and C/C++ and COBOL library files) provided by HP Consulting used by applications to interface with the Gateway server.
4. Java application program User written application code to process requests/transactions. 

Persistent Cloud Services (PCS) is an architecture designed to enable the NonStop to be a controller of, and a participant with, a group of commodity servers or Cloud deployments. As such, it allows NonStop to be an important component of a Converged Infrastructure environment.

In general terms, PCS enables the extension of Pathway functionality to commodity servers or virtual servers running in public or private clouds.
