High Availability and Disaster Recovery Models in PAM360

In today’s complex IT environments, maintaining continuous access to privileged information is essential for business continuity and security. PAM360 provides a comprehensive suite of High Availability (HA) and Disaster Recovery (DR) models, specifically crafted for both PostgreSQL and Microsoft SQL (MS SQL) databases, to safeguard privileged data and protect critical enterprise systems from disruptions. These models are designed to enable seamless access to data, minimize downtime, and ensure rapid recovery, supporting organizations in mitigating risks associated with data interruptions.

PAM360’s HA and DR offerings extend beyond basic failover setups, including features such as Application Scaling, and Read-Only servers. This suite of distinct models provides organizations with flexible and scalable options that support both performance and resilience needs, ultimately enabling businesses to thrive in unpredictable circumstances.

This document offers an in-depth exploration of each HA and DR model available within PAM360, detailing how each framework operates, how databases behave across various HA setups, and how PAM360 minimizes downtime to maintain operational continuity. Below are the core HA models supported by PAM360, which are discussed further in the documentation links provided.

1. High Availability Models in PAM360

  1. Failover Service Model - PAM360 enables the setup of failover services using MS-SQL clusters, which automatically transition operations to standby servers in the event of a primary server failure. This model ensures that services remain active without manual intervention, reducing downtime and maintaining access to privileged information.
  2. Read-Only Server Model - The Read-Only Server functionality enhances PAM360’s high availability strategy by adding a critical layer of resilience. Configurable across multiple locations, Read-Only servers are dedicated to executing read operations, thereby preserving data integrity by preventing modifications. These servers operate in synchronization with the primary server, effectively functioning as mirror servers.
    In the event of a primary server failure or catastrophic incident, any Read-Only server can seamlessly transition to assume the role of the primary server, ensuring uninterrupted operational continuity. Unlike other high-availability configurations, which allow for only one secondary server, organizations can configure multiple Read-Only servers in various locations, offering greater flexibility.
  3. Application Scaling Model - PAM360’s Application Scaling feature allows organizations to distribute database loads across clusters, enhancing both performance and accessibility. This model not only supports high availability but also offers resilience through load balancing, preventing service interruptions during heavy usage periods.
  4. Secondary Server Architecture Model - In this model, PAM360 leverages a network of secondary servers that are configured to replicate the primary server’s state, providing additional layers of redundancy. Secondary servers act as standbys, ensuring operational continuity and preventing data loss even in severe disruptions.

2. Operational Continuity with Database Backup and Recovery

In addition to high availability models, PAM360 offers flexible database backup and restore options, tailored for both PostgreSQL and MS-SQL, ensuring swift data recovery in case of a catastrophic event. These options allow you to schedule backups regularly, store backup files securely, and restore data efficiently, so your organization can recover quickly from data loss or corruption.
