Multi-Cloud SaaS Applications: Speed + Availability = Success!

In this blog post, we talk about how to run applications across multiple clouds (i.e. AWS, Google Cloud, Microsoft Azure) using Continuent Clustering. You want your business-critical applications to withstand node, datacenter, availability-zone or regional failures. For SaaS apps, you also want to bring data close to your application users for faster response times and a better user experience. With cross-cloud capability, Continuent also helps avoid lock-in to any particular cloud provider.

The key to success for the database layer is to be available and respond rapidly.

From both a business and operational perspective, spreading the application across cloud environments from different vendors provides significant protection against vendor-specific outages and vendor lock-in. Running on multiple platforms provides greater …

Mastering Continuent Clustering Series: Converting a standalone cluster to a Composite Primary/DR topology using INI configuration

In this blog post, we demonstrate how to convert a single standalone cluster into a Composite Primary/DR topology running in two data centers.

Our example starting cluster has 5 nodes (1 master and 4 slaves) and uses service name alpha. Our target cluster will have 6 nodes (3 per cluster) in 2 member clusters alpha_east and alpha_west in composite service alpha.

This means that we will reuse the existing service name alpha as the name of the new composite service, and create two new service names, one for each cluster (alpha_east and alpha_west).

Below is an INI file extract example for our starting standalone cluster with 5 nodes:

[defaults]
...

[alpha]
connectors=db1,db2,db3,db4,db5
master=db1
members=db1,db2,db3,db4,db5
topology=clustered

To convert the above configuration to a Composite Primary/DR:

  1. First you must stop all services on all existing nodes:
    shell> stopall …

Recommended fix for MySQL Checker Query Script for Tungsten Clustering

We have identified an issue in a script that is executed as part of the Tungsten Clustering solution. The script itself executes a small query against the internal tables used by the replicator in order to help identify the current status and latency of the replication process. We believe this script may occasionally fail under some very specific conditions, which would not normally be an issue, but the knock on effect is to create Out of Memory errors and instability in the way identifying the current replication state is handled.

The issue has been fixed in the upcoming 6.0.1 and 5.3.2 releases, but we have identified that customers on versions of the Tungsten Clustering solution from v4.0 upwards would benefit from using an updated version of the script.

If you are using Tungsten Clustering 4.x or higher, it is recommended that you apply this patch to improve the stability of your clustering …
