What is an AccuWeb.Cloud PostgreSQL Cluster?

A managed HA PostgreSQL setup with automated replication, failover, and optional Pgpool‑II load balancing.

What are the core components of a PostgreSQL Cluster?

It includes data directory, PostgreSQL engine, (optional) Pgpool‑II, and a Cluster Admin Panel.

How do I manage my PostgreSQL Cluster?

Use the AccuWeb.Cloud dashboard or Cluster Admin Panel to monitor, scale, backup, and configure.

Can I customize the PostgreSQL Cluster?

Yes—select version, region, Pgpool‑II, isolation, scaling rules, and resource size.

How do I get started with a PostgreSQL Cluster?

Go to Marketplace → choose PostgreSQL Cluster → configure → install—deployment completes in minutes.

Can I scale my PostgreSQL Cluster on demand?

Yes, you can add replicas, scale CPU/RAM, or use auto‑scaling based on traffic.

What if a node fails in the cluster?

Pgpool‑II promotes a secondary to primary and auto‑provisions a new node without downtime.

Does the cluster ensure ACID‑compliant transactions?

Yes, PostgreSQL’s engine provides full ACID compliance across the cluster.

Is Pgpool‑II included?

Pgpool‑II is optional, available for load balancing and automated failover.

Can I isolate network environments?

Yes, enable network isolation for secure multi‑tenant or private setups.

Next-Gen PostgreSQL Cluster Hosting

Globally Synced PostgreSQL Cluster

Deployed using Primary–Secondary–Secondary architecture for superior redundancy.
Integrated with Pgpool-II Load Balancer, enabling real-time read/write request distribution.
Disaster Recovery ready even if a full region fails, your DB remains accessible.
Choose separate regions for Load Balancer to reduce latency across global user bases.
Fully containerized, with auto-scaling infrastructure to support fluctuating demand.
Compatible with modern stacks (Node.js, Python, Django, Laravel, etc.) and CI/CD integrations.
Ideal for eCommerce, SaaS platforms, multi-tenant apps, and analytics platforms.

Network Isolation - Multi-Tenant PostgreSQL Security

Account-based isolation: Environments across different users can't communicate unless explicitly authorized.
Create internal groups within the same account that stay logically and securely separated.
Granular control over node-level access only approved services can establish connections.
Ideal for fintech, healthcare, government, or high-compliance apps.
Reduces lateral attack surface, supports zero-trust architecture, and aligns with best cloud security frameworks.
Fully visible and configurable via AccuWeb.Cloud’s modern dashboard UI.

Key Features of PostgreSQL Cluster

Automatic Failover Protection

AccuWeb.Cloud ensures that your PostgreSQL Cluster is equipped with Automatic Failover Protection through the use of Pgpool-II Load Balancer. This critical feature guarantees that:

If the main database server goes down, the Pgpool-II Load Balancer automatically detects the failure and promotes one of the backup databases to become the new primary.
Once the failed server comes back online, it is seamlessly re-integrated into the cluster as a backup. Any data lost during its downtime is restored using the pgrewind tool, ensuring the cluster remains consistent.

High Availability

High Availability (HA) is a cornerstone of the PostgreSQL Cluster. AccuWeb.Cloud provides a highly resilient setup that ensures:

Data is replicated across multiple servers in real time, which minimizes the risk of data loss in case of failure.
The main server is backed up by one or more secondary nodes, ensuring that if one node goes down, others can continue to serve requests with minimal impact on performance.

Asynchronous Replication

PostgreSQL on AccuWeb.Cloud uses Write-Ahead Logging (WAL), the fastest and most efficient method for asynchronous data replication. In this setup:

The main database server operates in archiving mode, writing WAL files (logs of changes to the database) to storage.
These logs are then sent to the backup server, which operates in recovery mode.

SSL/TLS Encrypted Connections

For added security and data protection, AccuWeb.Cloud allows users to enable SSL/TLS encrypted connections for their PostgreSQL Cluster. This ensures:

All data transferred between the client and server is securely encrypted, safeguarding sensitive information from eavesdropping or tampering.
SSL/TLS encryption can be enabled from the add-on options in the AccuWeb.Cloud dashboard.

FAQs on PostgreSQL Cluster Hosting

An AccuWeb.Cloud PostgreSQL Cluster is a fully managed, high-availability hosting solution that deploys multiple PostgreSQL nodes with automated replication and failover. It ensures seamless uptime, handles large datasets efficiently, and provides fault tolerance via primary-secondary architecture and optional Pgpool-II load balancing.

Data Directory: Stores PostgreSQL-managed files including databases, tables, indexes, and logs.
PostgreSQL Engine: The server-side program that handles queries, transactions, and client connections.
Pgpool-II Load Balancer (optional): Manages traffic between primary and secondary nodes for better performance and availability.
Cluster Admin Panel: A visual interface within AccuWeb.Cloud for easy monitoring, scaling, and configuration.

You can manage it via:

AccuWeb.Cloud Dashboard – for real-time monitoring, configuration, scaling, and traffic routing.
Cluster Admin Panel – to control PostgreSQL settings, manage backups, set replication rules, and monitor performance metrics.

Absolutely! AccuWeb.Cloud offers full customization at deployment:

Choose your PostgreSQL version (e.g., v15, v16).
Enable or disable Pgpool-II for automatic traffic management.
Select your preferred deployment region for reduced latency.
Configure auto-scaling policies based on traffic and compute demand.
Isolate environments using Network Isolation for secure multi-tenant setups.

Getting started is quick and no DevOps expertise is needed:

Log into your AccuWeb.Cloud account.
Go to the Marketplace → Choose Clusters.
Select PostgreSQL Primary-Secondary Cluster.
Configure your preferences (version, region, Pgpool-II, isolation, etc.).
Click “Install” and your cluster will be ready in minutes.

A single instance has no replication or failover protection. A clustered setup ensures high availability with redundant nodes and data replication, improving fault tolerance, load handling, and system resilience for production-grade environments.

Yes. With horizontal and vertical scaling, you can:

Add more nodes (read replicas) to improve performance.
Scale up resources (CPU/RAM) on existing nodes.
Automatically scales up/ down as per your traffic flow

Pgpool-II acts as a middleware that:

Distributes queries across nodes based on load.
Manages connection pooling for better concurrency.
Provides failover and automatic re-routing in case of node failure.
Offers query caching and read-write splitting (optional advanced configuration).

Yes. It's ideal for:

Real-time analytics using tools like Metabase, Superset, or Redash
Storing large datasets for ML/AI pipelines
Powering BI dashboards with low-latency read performance
Serving as the backend for time-series data (PostgreSQL) with TimescaleDB supported.

If the primary node fails:

Pgpool-II automatically promotes a secondary node.
Your data remains safe due to asynchronous replication.
A new node can be auto-provisioned with consistent data from backups or replicas.
