Presenter: Ray Fucillo
Task: Provide high availability (HA) and disaster recovery (DR) in diverse architectures that demand high performance, including replication over long distances
Approach: Give examples of mirror architectures in disparate environments, including geographically separated systems. Discuss performance considerations and advances in InterSystems’ mirroring technology
 

In this session you will learn about deploying Mirroring to provide HA and DR in diverse architectures that demand high performance and throughput. Challenges and solutions to achieving high throughput will be covered along with mirror architectures that involve long distances and disparate environments.

Presenter: Mark Bolinsky
Task: Decide whether a converged infrastructure is ideal for your enterprise applications
Approach: Discuss best practices and provide guidance on the right questions to ask
 

The traditional use of “SAN storage” is no longer the only choice for deploying enterprise application. Software defined data centers are making inroads into enterprise data centers, and there is good reason for it. There is the potential for significant infrastructure cost savings, architecture simplification, reduced administration costs, and depending on the configuration - even better performance. This session will discuss some best practices and outline decision guidance to help you ask the right questions when considering hyper-converged architectures.

Presenter: Murray Oldfield
Task: Deploy applications based on InterSystems’ technology using VMware.
Approach: Provide a checklist of factors to consider, particularly when deploying a production database application that requires high availability
 

Are you ready to deploy your applications on a virtualized architecture? This talk will highlight what you need to plan and do when deploying applications built on ISC data platforms using VMware. Special focus on what you need to know when planning for highly available (HA) production database applications.

++ Update: August 1, 2018

The use of the InterSystems Virtual IP (VIP) address built-in to Caché database mirroring has certain limitations. In particular, it can only be used when mirror members reside the same network subnet. When multiple data centers are used, network subnets are not often “stretched” beyond the physical data center due to added network complexity (more detailed discussion here). For similar reasons, Virtual IP is often not usable when the database is hosted in the cloud.

Network traffic management appliances such as load balancers (physical or virtual) can be used to achieve the same level of transparency, presenting a single address to the client applications or devices. The network traffic manager automatically redirects clients to the current mirror primary’s real IP address. The automation is intended to meet the needs of both HA failover and DR promotion following a disaster.

Introduction

This document is intended to provide a survey of various High Availability (HA) strategies that can be used in conjunction with InterSystems Caché, Ensemble, and HealthShare Foundation. This document also provides an overview of the various types of system outages that can occur, as well as how each strategy would handle a given outage, with the goal of helping you choose the right strategy for your specific deployment.

The strategies surveyed in this document are based on three different HA technologies:
