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 …

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 …

Amazon RDS Multi-AZ Deployments and Read Replicas

Amazon RDS is a managed relational database service that makes it easier to set up, operate, and scale a relational database in the cloud. One of the common questions that we get is “What is Multi-AZ and how it’s different from Read Replica, do I need both?”.  I have tried to answer this question in this blog post and it depends on your application needs. Are you looking for High Availability (HA), read scalability … or both?

Before we go to into detail, let me explain two common terms used with Amazon AWS.

Region – an AWS region is a separate geographical area like US East (N. Virginia), Asia Pacific (Mumbai), EU (London) etc. Each AWS Region has multiple, isolated locations known as Availability Zones.

Availability Zone (AZ) – AZ is simply one or more data …

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 …
