Great SaaS - starts with great software. But not enough is said about the people and values behind great software; so that’s what I want to talk about here.
This blog explains data replication and clustering in a way that anybody can understand.
Enterprises require high availability for their business-critical applications. Even the smallest unplanned outage or even a planned maintenance operation can cause lost sales, productivity, and erode customer confidence. Additionally, updating and retrieving data needs to be robust to keep up with user demand.
Tungsten Clustering offers a graphical administration tool called the Tungsten Dashboard™ to help with your management burden. The GUI makes the deployment much easier to visualize and administer.
Think about it - your global, cloud-based application needs to be online and available for the business to run. Downtime is to be avoided like the plague. Perhaps you even have multiple cloud providers to span.
How do we create a database service layer that handles all kinds of failures?
Think about it - your application needs to be online and available for the business to run. Downtime is to be avoided like the plague. The buzz is all about five nines of uptime.
How do we as systems architects, DBAs and sysadmins create an environment where routine maintenance is not a thing to be feared and put off, but embraced to allow for proper and needed updates and upgrades to take place?
In this blog post, we talk about how to run applications across multiple clouds (i.e. AWS, Google Cloud, Microsoft Azure) using Tungsten 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, Tungsten also helps avoid lock-in to any particular cloud provider.
This distributed topology, perfect for multi-region SaaS models, allows you to have all the benefits of high availability with centralized writes and local reads for all regions. Latency is limited only by the WAN link and the speed of the target node.
This blog post covers global MySQL / MariaDB / Percona Server clustering with Active/Active meshed replication, the architecture commonly used for globally-distributed SaaS companies.
