Geo-Distributed Galera Clusters
Galera Cluster provides high availability and scalability for MySQL. While this provides high availability in a local region or site, it does not provide any provisions for disaster recovery (DR) or any multi-site deployment in general, so let’s explore how we could extend the functionality of Galera Cluster to deploy at geo-scale.
Geo-Distributed Oracle MySQL InnoDB Clusters
Oracle MySQL InnoDB Cluster provides high availability and scalability for MySQL. An InnoDB Cluster consists of 3 or more MySQL instances in a local network with group replication enabled, MySQL Shell which is used for management of the cluster, and optionally MySQL Router to provide basic routing from applications to the cluster. While this provides high availability in a local region or site, it does not provide any provisions for disaster recovery (DR) or any multi-site deployment in general, so let’s explore how we could extend the functionality of InnoDB Cluster to deploy at geo-scale.
Migrate from Galera to Tungsten Clustering without Downtime
Migrating from Galera to Tungsten Clustering is easy with the tools provided by Tungsten Clustering. Because replication happens in the background, applications can stay online with a quick cutover to Tungsten Clustering when ready.
Do-it-Yourself (DIY) vs. Tungsten Clustering for MySQL High Availability (HA), Disaster Recovery (DR) and Geographic Distribution
For the sixth in the Competitor Comparison series in which we look at the main solutions for MySQL high availability, disaster recovery and geographic distribution, I got a chance to interview Matt Lang, Customer Success Director, Americas at Continuent. We focused on highly available, geo-scale, multi-region MySQL for mission-critical sites and apps with Do-it-Yourself (DIY) solutions as compared to MySQL clustering with Continuent Tungsten, the only complete, fully-integrated clustering solution for MySQL - on-premises, in the cloud, hybrid-cloud or multi-cloud.
Oracle’s InnoDB Cluster - High Noon with Tungsten Clustering for MySQL High Availability (HA), Disaster Recovery (DR) and Geographic Distribution
This is the fifth blog in our ‘High Noon’ comparison series in which we look at the main solutions for MySQL high availability, disaster recovery and geographic distribution. Here we focus on highly available, geo-scale, multi-region MySQL for mission-critical sites and apps with Oracle’s InnoDB Cluster as compared to MySQL clusters with Continuent Tungsten, the only complete, fully-integrated clustering solution for MySQL - on-premises, in the cloud, hybrid-cloud or multi-cloud.
MS Azure MySQL - High Noon with Tungsten Clustering MySQL High Availability (HA), Disaster Recovery (DR) and Geographic Distribution
This is the next in our ‘High Noon’ comparison series in which we look at the main solutions for MySQL high availability, disaster recovery and geographic distribution. Here we focus on highly available, geo-scale, multi-region MySQL for mission-critical sites and apps with Microsoft Azure Database for MySQL as compared to native MySQL, MariaDB clusters with Continuent Tungsten in the cloud, hybrid-cloud, multi-cloud or on-premises.
Alternative MySQL and MariaDB Clustering Solutions: 'High Noon' Competitor Comparisons
Why do Continuent customers say year after year that Tungsten Clustering is a better MySQL HA/DR/Geo-Scale clustering and replication technology - in the cloud, on-prem, hybrid-cloud, multi-cloud - compared to alternatives such as Amazon Aurora for MySQL, Galera Cluster and host of others? We have put together a comprehensive comparison so you can learn about the pros and cons of various MySQL solutions for business-critical and mission-critical apps - and make an informed decision about what’s best for your needs and environment!
Oracle's MySQL InnoDB Cluster versus Tungsten Clustering for MySQL
We’ve been receiving requests recently from MySQL users wanting to understand how InnoDB Cluster compares to Tungsten Clustering, our MySQL HA, disaster recovery, and geo-clustering solution. In response we have come up with this comparative outline, looking at some of the key features of each.
How free is your Open Source software...really?
When it comes to that little piece of software with a $0 price tag, just take a moment and ask yourself if it really is going to be free. Yes, there are many perfectly valid use cases for using OSS software, but ensure you fully understand the risks and potential business imapact from an outage first.
Watch the Replay: Is “Free” Good Enough for Your MySQL Environment?
Watch the replay of a webinar with our colleagues from Datavail and hosted by DBTA during which we discuss whether “free” is really good enough for business-critical MySQL database environments.
