One of the common misconceptions about Continuent is that because Tungsten does not have an open source license, we do not support open source. In fact, quite the opposite, in everything we do. The whole purpose of Tungsten Clustering is to empower and enable teams that build business-critical applications on open source databases.
This leads us to the subject of this blog: how Tungsten is designed for openness.
There are many options for databases, and many organizations use multiple different types for their various use cases. In this blog we explore the use case of a business-critical or mission-critical application that requires a performant, robust and reliable OLTP RDBMS, and a few reasons to stick with a native open source database for this use case.
Hop on-board and sail the San Francisco Bay with the Founder and CEO of Continuent, Eero Teerikorpi, as he zeros in on one of the reasons customers love Continuent’s 24/7/365 customer service: speed. Of course, speed isn’t everything - but when combined with highly experienced and available DBAs, SysAdmins and Architects - it’s hard to find better peace of mind about your business-critical databases.
This is the third post in a short series about Tungsten Clustering topologies. In this post we will highlight the key differences between Composite Active/Passive, Composite Active/Active (CAA), and the newly available Dynamic Active/Active topology. In short, DAA blends the simplicity of CAP with the automated continuous operations of CAA.
You’ve seen the recent news about AWS outages; enterprises have to think about where their physical AWS data centers are and treat them as a single point of failure. As such, enterprises running business-critical and mission-critical applications are accounting for geography of public cloud resources in their business-continuity plans. Learn about a solution for continuous operations for your MySQL database that’s a step above traditional MySQL Disaster Recovery (DR).
In this short post we will highlight the key differences between Multi-Site Active/Active (MSAA) and Composite Active/Active (CAA) topologies. The core principle behind an active/active topology is that you have more than one writable cluster. So why do we have more than one type of Active/Active topology?
So we’ve established how important backups are, RTO, RPO, and how you can be a hero by having backups that align with business objectives. We just need to pick a good backup tool(s) to take backups of your MySQL database. Databases evolve, grow, and business needs change. That’s why it is important to constantly reevaluate your backup strategy, because what worked last year may not be appropriate this year in terms of RPO/RTO, retention, or costs.
As system administrators, we are called upon to be responsible for a vast quantity of discrete subsystems, each with its own set of operating rules. When starting and stopping any subsystem, it is the best practice to do so gracefully whenever possible to ensure data integrity. In this blog post, we detail the best practices for stopping and starting a Tungsten Cluster.
Remember what 2001 looked like from a technology point of view? In this vlog, the Founder and CEO of Continuent, industry veteran Eero Teerikorpi, tells the story of the beginning of Continuent, and the bold vision that got us here. Since 2001, Continuent has pioneered the need for cloud-savvy business-critical MySQL databases that are platform-agnostic, highly-available, and globally-scaling.
We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA versions 6.1.16 are now available. Tungsten allows enterprises running business-critical MySQL database applications to cost-effectively achieve continuous global operations with commercial-grade high availability (HA), geographically redundant disaster recovery (DR) and geographically distributed active/active.
Recently, a Continuent customer asked: “What is your approach for scaling up MySQL clusters for a higher number of queries per second and larger data sets?” Scaling, like availability, is a multifaceted question. In this blog post we will detail and discuss the best practices for scaling Tungsten Clusters.
In this blog post we examine in depth how to best provision one MySQL database cluster node from another using rsync. Since there are many possible ways to handle provisioning by rsync, we will do multiple posts on the topic, starting with the most basic - both the source and target database nodes are fully offline for the duration of the rsync. While this is not an ideal scenario because two nodes are down at once, it does allow one replica to be provisioned from another replica when all else fails.
