The best MySQL multi-master solution gets even better

The best (and truly the only) MySQL multi-master, multi-site solution on the market gets even better! Continuent is happy to announce immediate availability of Continuent Tungsten 1.5.

New Continuent Tungsten 1.5 allows you to build multi-site, disaster recovery (DR) and multi-master solutions with ease:

  • Multi-Master Operations - Tungsten can support your multi-master operations today by linking together highly-available, scalable Tungsten clusters with bi-directional, cross-site replication.
  • Multi-Site-Aware Connectivity - Tungsten is now aware of all the database servers in the multi-site-configuration and intelligently routes the requests to the right database server.
  • Easy Multi-site, Disaster Recovery Deployment - One-step command to deploy multiple Tungsten clusters in two or more data centers or cloud regions in a matter of minutes, with automatic checking of all pre-requisites, and links them together, seamlessly, with cross-site replication.
  • Isolate and Handle Local Failures Automatically - Tungsten automatically fails over within each local cluster, and transparently reconfigures resources at remote sites to maintain the cross-site replication.
  • Site-Level Failover - Fail over to a DR site with a single 'failover' command.
Continuent Tungsten does not require any application changes, and runs on all flavors (MySQL Community, MySQL Enterprise, MariaDB and Percona Server) and all versions of MySQL (5.0, 5.1, 5.5). When you review your HA options, please note that this 'no-changes' promise is really not true with many other MySQL HA solutions currently available. 

If you are currently using MySQL replication (no automatic master failover), MMM, MHA or DRBD (50% performance penalty), you should consider Continuent Tungsten instead. Ask us about our special promotion for replacing your current HA solution with Continuent Tungsten!

Webinar 5/31: Building a multi-master, multi-region MySQL solution in the Cloud

Click here to register!
Growth is good, right? Yes, unless you are the one building and managing a MySQL database tier to handle all this growth! Your company has built a great new app and launched it in the cloud. And now you are seeing what many wish for: an exponential adoption of your app. 


But is your database tier really up to the job? 
  • What happens if your MySQL server fails?
  • Can you fail over to a replica quickly?
  • Do you even have a replica to fail over to?
  • Can you keep your app available even as you upgrade your database schema or add additional or more powerful database servers?
  • Can you easily scale read operations by load balancing them across a set of replicas?
  • Do you have a way to maintain a set of data that is globally accessible, across Amazon EC2 regions in the USA, Europe, APAC, Japan etc., and that allows app users to get to and update their data with minimal latency, no matter where they are located?
  • How do you make sure that an update made in a database in Japan gets propagated to databases in Europe, USA, APAC etc. with minimal latency? 
That's a lot of questions... and this webinar will answer them. Join us to learn how Continuent Tungsten can help you solve these issues by combining local MySQL clusters, for high-availability and scalability, with cross-region, multi-master replication to maintain a globally distributed database.

Webinar 5/17: MySQL High Availability Realized


High availability is about more than just making sure that applications can get to your data, even if there is a failure:
  • How about when you are upgrading your database schema
  • What if you need to add memory to a database server or reconfigure/restart MySQL
  • If your apps want to read data from a MySQL slave, how can you be sure they are not reading stale data without re-coding your apps
  • What if your main data center takes a hit
  • And what if you want better MySQL stability, performance, and simplified administration, but you cannot or do not want to re-write your apps or convert your current data to run with a proprietary MySQL re-write or a promised new version of MySQL?
In this live webcast, Robert Hodges (CEO) and Edward Archibald (CTO) will go through a detailed case study to show you how you can start with the MySQL version/build, along with the data and apps that you already have, and iteratively build up a highly-available, scalable, multi-site database infrastructure where you can perform complex data management tasks with single commands.

Robert & Ed will run live demos of the following:
  • Transition from MySQL 'native' replication to a Tungsten Enterprise cluster with zero app downtime
  • Reading consistent data from slaves without application changes (SmartScale)
  • Schema upgrade on the master database server with no app downtime (switch operation)
  • Automated fail over when a MySQL database server crashes
  • Recovery of a failed master to a fully operational slave with a single command
  • Switch of database operations to a remote site with no app down time (geo-clustering, cross-site 'switch' operation).
