Core Metrics for WordPress and MongoDB on OVH Effective server monitoring hinges on tracking the right metrics. For a WordPress application backed by MongoDB on OVH, this means a dual focus: the health of the web server stack (PHP-FPM, Nginx) and the performance of the MongoDB cluster. WordPress Stack Monitoring The WordPress application itself, typically […]
Terraform Provider Configuration for Linode To begin provisioning infrastructure on Linode using Terraform, we first need to configure the Linode provider. This involves specifying your Linode API token and potentially a default region. The API token grants Terraform the necessary permissions to interact with your Linode account. It’s crucial to manage this token securely, ideally […]
Establishing a Robust Monitoring Baseline for Magento 2 on AWS Maintaining a high-availability Magento 2 deployment on AWS necessitates a multi-layered monitoring strategy. This isn’t just about uptime; it’s about performance, resource utilization, and proactive issue detection. We’ll focus on key AWS services and custom instrumentation to achieve this. Core AWS Metrics for EC2 Instances […]
Proactive MySQL Replication Lag Monitoring MySQL replication lag is a silent killer of data consistency and application availability. On DigitalOcean, managing a cluster of MySQL instances, especially for a Ruby application, demands vigilant monitoring of replication status. We’ll focus on a practical, script-driven approach using standard MySQL tools and a simple shell script, deployable via […]
Establishing a Highly Available PostgreSQL Cluster with Patroni For critical PostgreSQL deployments, a robust disaster recovery strategy is paramount. This involves not just backups, but an automated failover mechanism that minimizes downtime. We’ll architect this using Patroni, a template for PostgreSQL HA, which leverages etcd or Consul for distributed configuration and leader election. This example […]
Establishing a Multi-Region Disaster Recovery Strategy for Shopify on OVHcloud This document outlines a robust, automated multi-region disaster recovery (DR) strategy for Shopify architectures hosted on OVHcloud infrastructure. The primary objective is to minimize Recovery Time Objective (RTO) and Recovery Point Objective (RPO) in the event of a regional outage, ensuring business continuity for critical […]
Proactive PostgreSQL Cluster Health Checks with `pg_stat_activity` and `pg_stat_replication` Maintaining the health of a PostgreSQL cluster, especially in a distributed environment on DigitalOcean, requires more than just basic CPU and memory monitoring. We need to dive deep into the database’s internal state. Key views like pg_stat_activity and pg_stat_replication provide invaluable real-time insights into query performance, […]
Designing for Resilience: Multi-Region DynamoDB and PHP Auto-Failover Achieving true high availability in a cloud-native environment necessitates a robust disaster recovery (DR) strategy. For applications built on AWS, particularly those leveraging DynamoDB and PHP, this often translates to architecting for automated failover across multiple AWS regions. This isn’t merely about backups; it’s about maintaining application […]
Terraform Project Structure and Provider Configuration We’ll begin by establishing a robust Terraform project structure. This organization is crucial for managing complexity, especially as your infrastructure grows. Our core configuration will reside in main.tf, variables in variables.tf, and outputs in outputs.tf. For this example, we’ll focus on provisioning a secure Ruby cluster on Google Cloud […]
Establishing a High-Availability MySQL Cluster with Orchestrator For robust disaster recovery and automated failover, a multi-node MySQL cluster is paramount. We’ll leverage Orchestrator, a popular MySQL replication topology manager, to achieve this. Orchestrator simplifies the management of complex replication topologies and provides automated failover capabilities. Our setup will involve at least two MySQL instances, ideally […]
