In this blog post we will explore the procedure for getting an email notification every time a file is uploaded to an AWS S3 bucket. Instead of having to poll the AWS S3 bucket manually for new uploads, we wanted a way to be notified by email every time a file landed. The solution was a combination of an SNS Topic used by an SNS Subscription, and called by an S3 bucket Event notification.

This blog takes a look at three stacks: networking, LAMP, and the modern MySQL database clustering stack. The networking stack is a foundational element of geo-distributed MySQL database services. LAMP is a common software solution stack used by web and other client-server applications. The modern database clustering stack enables multi-site, multi-region and globally distributed MySQL database systems for continuous operations, which Tungsten Clustering provides in a complete, fully-integrated and tested package.

“How can I simulate a failure of the Active half of an Active/Passive Cluster to test the Failover to the Passive half?”

In this blog post we explore the best practices for simulating a failure of the Active cluster in an Active/Passive Composite Cluster.

A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them using private IP addresses. Instances in either VPC can communicate with each other as if they are within the same network. This blog provides step-by-step instructions on how to set up VPC networking between regions (also known as inter-region VPC peering connections).

As we are all being pushed to the limit to meet unprecedented demands online, the pandemic shined a light on many new frontiers and achievements in technology. This blog is about continuous MySQL database operations when you have a global user base, particularly the VMworld 2021 Global Multi-Cloud conference.

MySQL High Availability (HA) is typically what architects and technologists look for in building business-critical and mission-critical applications, and they aspire to measure MySQL uptime in 4 or preferably more “nines.” This blog explores the modern world of continuous MySQL operations - cross-region, global, hybrid-cloud, and multi-cloud - and why you might need a different approach.

A short contemplation about the current state of the programming languages. What language to choose for a new project? What are the differences between them? Is there a best language for everything?

Oracle MySQL InnoDB Cluster provides high availability and scalability for MySQL. An InnoDB Cluster consists of 3 or more MySQL instances in a local network with group replication enabled, MySQL Shell which is used for management of the cluster, and optionally MySQL Router to provide basic routing from applications to the cluster. While this provides high availability in a local region or site, it does not provide any provisions for disaster recovery (DR) or any multi-site deployment in general, so let’s explore how we could extend the functionality of InnoDB Cluster to deploy at geo-scale.

This blog is about testing time and test suites management. “Battle-tested” is the Continuent Tungsten QA (Quality Assurance) guarantee. Continuent Tungsten is a clustering and replication solution for MySQL and MariaDB used by some of the largest MySQL estates to achieve continuous MySQL operations, locally and globally (HA, DR and Geo Distribution). Besides the stellar support team, and fully-integrated components, customers say: “Stability,” and, “Tungsten just works.”

Prometheus is one of the more popular ways to monitor your resources, and starting with version 7.0.0, Continuent has embedded the Prometheus exporter functionality into our core MySQL and MariaDB clustering products. This blog post covers how to enable the exporters, getting metrics and what metrics are available, along with cli tools, customizing the config, documentation references and a little bit about Grafana Dashboard for Tungsten Clusters.

If Continuent Support was depicted as a cartoon character, who would you choose? I know who I would choose...I’ll give you a clue...Very Fast...Beep Beep…

In this blog we will explore Continuent Support...What we do, how we do it and the tools available to the customer that make all that happen at lightning speed.

On August 20th, 2020 we released v6.1.6 of our Tungsten Clustering and Tungsten Replicator products. On August 17th, 2021, we released v6.1.14. In this blog we take a look back over the last 12 months and highlight some of our key updates and fixes.
