Watch the webinar replay: How Bluefin ensures 24/7 operation and application availability with Continuent Clustering

Watch the relay of this webinar and learn how Bluefin Payment Systems provides 24/7/365 operation and application availability for their PayConex payment gateway and Decryptx decryption-as-a-service, essential to point-of-sale (POS) solutions in retail, mobile, call centers and kiosks.

We discuss why Bluefin uses Continuent Clustering, and how Bluefin runs two co-located data centers with multimaster replication between each cluster in each data center, with full failover within the cluster and between clusters, handling 350 million records each month.

Global Read-Scaling using Continuent Clustering

Did you know that Continuent Clustering supports having clusters at multiple sites world-wide with either active-active or active-passive replication meshing them together?

Not only that, but we support a flexible hybrid model that allows for a blended architecture using any combination of node types. So mix-and-match your highly available database layer on bare metal, Amazon Web Services (AWS), Azure, Google Cloud, VMware, etc.

In this article we will discuss using the Active/Passive model to scale reads worldwide.

The model is simple: select one site as the Primary where all writes will happen. The rest of the sites will pull events as quickly as possible over the WAN and make the data available to all local clients. This means your application gets the best of both worlds:

  • Simple deployment with no application changes needed. All writes …

Mastering Continuent Clustering Series: Global Clustering with Active/Active Meshed Replication

Did you know that Continuent Clustering supports having clusters at multiple sites world-wide with active-active replication meshing them together?

Not only that, but we support a flexible hybrid model that allows for a blended architecture using any combination of node types. So mix-and-match your highly available database layer on bare metal, Amazon Web Services (AWS), Azure, Google Cloud, VMware, etc.

The possibilities are endless, as is the business value. This strong topology allows you to have all the benefits of high availability with local reads and writes, while spreading that data globally to be accessible in all regions. Latency is limited only by the WAN link and the speed of the target node.

This aligns perfectly with the distributed Software-as-a-Service (SaaS) model where customers and data span the globe. Applications have access to ALL the …

Mastering Continuent Clustering Series: Tuning for High-Latency Links

What if I want the cluster to be less sensitive to network, especially WAN latency?

Continuent Clustering supports having clusters at multiple sites with active-active replication meshing them together.

This is extraordinarily powerful, yet at times high network latency can make it harder for messaging between the sites to arrive in a timely manner.

This is evidenced by seeing the following in the Manager log files named tmsvc.log:

2018/07/08 16:51:05 | db3 |  INFO [Rule_0604$u58$_DETECT_UNREACHABLE_REMOTE_SERVICE1555959201] - CONSEQUENCE: [Sun Jul 08 16:51:04 UTC 2018] CLUSTER global/omega(state=UNREACHABLE)

The delta is 37 seconds in the above example between state=UNREACHABLE and UNREACHABLE => ONLINE
