New Euro Partnership offers safe-haven from US Patriot Act
Severalnines and City Network launch first fully European ‘Database as a Service’

STOCKHOLM and LONDON, 23^rd November -Severalnines, provider of automation and management software for cloud database platforms, and City Network, the ‘data center in a browser’ company have announced the first fully European Database as a Service (DBaaS) solution - in beta form. The City Cloud Database Service is based and operated by companies in the European Union - offering European customers full compliance with EU Directive on Data Protection 95/46/EC and a safe haven from the reaches of the US Patriot Act.

EU customers can now benefit from the savings and flexibility enabled by cloud-based database services safe in the knowledge that they will not fall under the jurisdiction of the Patriot Act. Under the Patriot Act, data from EU users of US-owned cloud-based services can currently be shared with US law enforcement agencies without the need to tell the user.

“Small start-ups and large corporations are turning to the cloud in a bid to deploy and manage databases with as little overhead as possible - but they need to know their data is secure and that they retain the right and ability to control who accesses it,” says Vinay Joosery, chief executive officer at Severalnines.

“A fully managed database service will enable our customers to further reap the benefits of the cloud,” says Johan Christenson, Chairman at City Network. “We believe that a service owned and operated locally in the EU, and fully compliant with EU data protection laws, will be very particularly attractive for European companies. US companies with European operations will also benefit from the lower latency of a locally hosted solution.”

The MySQL based City Cloud Database Service enables companies to outsource the configuration and management of their databases and only pay for what they use. Specific benefits include:

• Web interface for easy provisioning

• Zero maintenance or administration – backups, patch management and replication handling are fully automated

• Performance Management – users have visibility of top queries and can drill-down into performance

• High Availability – failures are handled automatically to minimise downtime

• Scalability – users can add more instances at the click of a mouse

• Comprehensive user interface for administering databases; and

• Data import and export functionality to help move MySQL databases within the cloud.

The service relies on the Severalnines DataCloud platform, a database automation and management platform that helps companies run flexible databases anywhere, whether on their premises or in the cloud. It is based on City Network’s City Cloud computing platform which allows unlimited growth with a focus on stability, security and redundancy.

City Cloud Database Service is available in beta. Companies can apply for the trial by emailing dbaas@citycloud.eu. The service is available free of charge for the duration of the beta period, which will run until early 2012. More information is available on http://www.citycloud.eu/

Severalnines releases ClusterControl™ for MySQL Galera in cooperation with Codership

Tweet

Stockholm – October 25^th 2011

Severalnines, provider of automation and management software for easily usable, highly available and auto-scalable cloud database platforms, today announces the release of ClusterControl™ for MySQL Galera in cooperation with Codership, the replication experts organisation that leverages the latest developments in computer science to produce fast and scalable synchronous replication solutions that "just work" for databases and similar applications.

Introducing ClusterControl™ for MySQL Galera

ClusterControl™ for MySQL Galera enables customers to Deploy, Manage, Monitor and Scale a clustered MySQL database platform based on Galera Replication.

Developers and DBAs now have access to all of the features of Severalnines' flagship product ClusterControl™ specifically adapted to MySQL Galera.

Designed to address issues and needs of MySQL users relying on MySQL Replication, ClusterControl™ for MySQL Galera offers a complete set of tools to assist developers and administrators of all skill levels to deploy, manage, monitor and scale their replicated MySQL databases.

What is MySQL Galera?

MySQL Galera is a synchronous multi-master cluster for MySQL/InnoDB or, in similar words, a synchronous multi-master replication plug-in for InnoDB. It is very different from the regular MySQL Replication and addresses a number of issues including write conflicts when writing on multiple masters, replication lag and slaves being out of sync with the master. Users do not have to know which server they can write to (the master) and which servers they can read from (the slaves). With MySQL Galera you can simply write and read from any MySQL Server.

Galera Cluster Use Cases

Galera replication works for a wide variety of use cases for high availability and scalability where you tolerate no lost of transactions or no slave lag or you look for write/read scalability Here are some common use cases where Galera can be used.

· Read Master

o Traditional MySQL master-slave topology, but with Galera all "slave" nodes are capable masters at all times, it is just the application who treats them as slaves. Galera replication can guarantee 0 slave lag for such installations and due to parallel slave applying, much better throughput for the cluster.

· Write Scalability

o Distributing writes across the cluster will harness the CPU power in slave nodes for better use to process client write transactions. Due to the row based replication method, only changes made during a client transaction will be replicated and applying such a transaction in slave applier is much faster than the processing of the original transaction. Therefore the cluster can distribute the heavy client transaction processing across many master nodes and this yields in better write transaction throughput overall.

· WAN Clustering

o Synchronous replication works fine over the WAN network. There will be a delay, which is proportional to the network round trip time (RTT), but it only affects the commit operation.

· Disaster Recovery

o Disaster recovery is a sub-class of WAN replication. Here one data center is passive and only receives replication events, but does not process any client transactions. Such a remote data center will be up to date at all times and no data loss can happen. During recovery, the spare site is just nominated as primary and application can continue as normal with a minimal fail over delay.

· Latency Eraser

o With WAN replication topology, cluster nodes can be located close to clients. Therefore all read & write operations will be super fast with the local node connection. The RTT related delay will be experienced only at commit time, and even then it can be generally accepted by end user, usually the kill-joy for end user experiences is the slow browsing response time, and read operations are as fast as they possibly can be.

Multi-master and read slaves using Severalnines

Tweet This blog post shows how you can use the Severalnines Configurator for MySQL Replication to deploy a Multi-master replication setup, and install ClusterControl.
You can also watch videos showing what is described below or read an even more detailed tutorial.

When the deployment is finished you have a set of tools to manage and monitor replication, as well as to add new slaves, and to perform failover.
You can choose:

• The number of slaves you wish to connect to the master->relay master.
  
• whether you want to use MySQL 5.5.x or Percona 5.5.x
  
• Semi-sync replication or not (semi sync really recommended)
  
• cloud provider (on premise/EC2/Rackspace

Please note that your hosts must resolve to a valid ip. If 'hostname -i' resolves to nothing or to 127.0.0.1 it will not work.

We recommend also that you don't use bi-directional replication. It may sound like a good idea, but in practice it is challenging to get it working well.

When deployed you can easily perform tasks as:

• Add new slaves
• Failover
• View replication health information
• Stop/start replication links
• Stage slaves
  

The Configurator for MySQL Replication is a wizard-like application and you have to enter details about the setup you want to have. When this is done you will get a tar.gz that contains the deployment and management scripts.

ClusterControl

The deployment process will also install ClusterControl which is a set of monitoring agents and functionality to manage the database installation. The agents are deployed on each server and collects host information and information from the local MySQL server a particular agent is monitoring (such as replication statistics and status information).

One server (dedicated) is denoted the ClusterControl server. It is holding a database, CMON DB, that contains data about the monitored hosts, and the reporting data from the local agents is stored in this database. On this server a Controller is running and faciliates failover etc.

Moreover, the ClusterControl server exposes a web interface that can be used to graphically see the health of the replication cluster (after the deployment is done, take a web browser and point it to http://clustercontrolserver/cmon :

From ClusterControl you can then upload a schema, and start loading in data into a database. As well as doing GRANTs etc. In the Enterprise version you an also define performance probes (to make sure you system is not degrading over time), tune queries, try out new queries before putting them in production. You also have a Query Monitor and explains at your hands.

Failover is automatic (if the master fails, the relay will become the new master). When the master comes up again, it will connect to the new master and sync up, become the relay, and the slaves will failover to the relay. We also make use of the replication features of MySQL 5.5 (such as relay recovery) and a bunch of other techniques.

You can also add slaves or remove slaves with the click of a button, as well as scheduling backups.

Installation
When you have finished the wizard you get a package that you should deploy on the ClusterControl server:

tar xvfz s9s-mysql-55.tar.gz
cd s9s-mysql-55/mysql/scripts/install
./deploy.sh

The 'deploy.sh' script will create data directories, install initd scripts, create mysql users, apply database GRANTs (those you defined in the Configurator), and install ClusterControl.

A while in 'deploy.sh' replication will be started, and it can look like this:

*******************************************************************************
*                   Starting replication                                      *

After this, ClusterControl will be installed. If you are using RPM based installation there can be rpm dependency problems (we install libmysqlclient.so.16), but it can conflict with what comes with your distribution. Please let us know if this happens, contact us on community@severalnines.com.

Starting/stopping Replication and basic examples

After having executed deploy.sh, you can view the status of the mysql servers:

cd s9s-mysql-55/mysql/scripts/
./status.sh  -a
Master hosts
------------
10.30.30.31: up
10.30.30.32: up
Slave hosts
------------
10.30.30.33: up
10.30.30.34: up

To view the replication status:

cd s9s-mysql-55/mysql/scripts/
./repl-status.sh -a
master_host -->slave_host status  master_status  slave_status [binlog|m_pos|exec_pos|lag]
10.30.30.31 10.30.30.32 ok         binlog.000003:250 binlog.000003| 250| 250| 0
--- slaves follows ---
10.30.30.32 10.30.30.33 ok         binlog.000001:107 binlog.000001| 107| 107| 0
10.30.30.32 10.30.30.34 ok         binlog.000001:107 binlog.000001| 107| 107| 0

To stop replication between 10.30.30.32 (relay master) to 10.0.30.33 you can do:

cd s9s-mysql-55/mysql/scripts/
./stop-repl.sh -m 10.30.30.32 -s 10.30.30.33
stopping replication between 10.30.30.32 --> 10.30.30.33
replication [stopped] 10.30.30.32 --> 10.30.30.33

To start replication again you can do:

cd s9s-mysql-55/mysql/scripts/
./start-repl.sh -m 10.30.30.32 -s 10.30.30.33
starting replication between 10.30.30.32 --> 10.30.30.33 (change master=0, reset master=0)
replication [started] 10.30.30.32 --> 10.30.30.33

Other options for 'start-repl.sh' is -r (for reset master, dangerous), -c (change master). Normally these options are not needed but you can use them in conjuction with -l (logpos) and -f (binlog file) if you want to start replication from a particular position.

And we can check the replication status:

ubuntu@ip-10-49-122-115:~/s9s-mysql-55/mysql/scripts$ ./repl-status.sh -a
serverid master_host -->slave_host status  master_status  slave_status [binlog|m_pos|exec_pos|lag]
1      10.48.207.130 10.48.139.24 ok         binlog.000005:494 binlog.000005| 494| 494| 0
2     replication not activated - you must start replication on this link.
--- slaves follows ---
3      10.48.139.24 10.49.122.56 ok         binlog.000005:485 binlog.000005| 485| 485| 0
4      10.48.139.24 10.49.110.183 ok         binlog.000005:485 binlog.000005| 485| 485| 0

Severalnines releases ClusterControl™ for MySQL Replication v. 1.1.9

Tweet Stockholm - October 4th 2011

Severalnines, provider of automation and management software for easily usable, highly available and auto-scalable cloud database platforms, today announces the latest release of its flagship product ClusterControl™ for MySQL Replication.

Introducing ClusterControl™ for MySQL Replication v.1.1.9

ClusterControl™ for MySQL Replication enables customers to Deploy, Manage, Monitor and Scale a clustered database platform based on the standard MySQL Replication.

Developers and DBAs now have access to all of the features of Severalnines' flagship product ClusterControl™ specifically adapted to MySQL Replication.

Automated fail-over with ClusterControl™

Standard MySQL Replication is easy to set up, and is probably the most widely used mechanism to provide high availability for MySQL. Unfortunately, it is somewhat fragile. There is no support for fail-over. Slaves can easily end up with different data from the master. Diverging datasets can cause replication to stop. Crashing masters can corrupt binary logs, which means replication is not possible any more.

ClusterControl™ addresses the problems associated with master fail-over and resynchronizations, and avoids data loss by taking advantage of semi-sync replication in MySQL 5.5.

ClusterControl™ automates fail-over and reconfiguration of the replication setup to keep the Replication cluster stable and running. This online tutorial explains the MySQL Replication architecture, and how different types of failures are handled.

Users can try it now by generating their deployment package.

MySQL Clusters on Amazon EC2 - verified AMIs

Tweet We regularly receive questions from our user community with regards to which AMIs to use when deploying database clusters on Amazon EC2.

As part of our ongoing development work on the Severalnines Configurator and ClusterControl, we have recently done some testing on deploying MySQL Cluster on EC2 using Severalnines on three different AMIs. We thought we should share the results of these tests, hence the reason for this week's blog!

If you would like to test such a deployment yourself, feel free to use the parameters and guidelines below to do so. You can also check out these new videos to see Severalnines technology in action prior to getting started with your testing.

These are the three AMIs that we have tested the deployment on so as to have a good representative mix:

* RightImage_CentOS_5.4_x64_v5.5.9
* Amazon QuickStart AMI: amzn-ami-2011.02.1.x86_64-ebs
* Canonical AMI: ubuntu-maverick-5g-64bit

Of course, it would be great to hear from you on how your testing went and on what AMIs you are currently using yourself. Feel free to share your feedback with us on Facebook, Twitter, LinkedIn or leave a comment on this blog.

Here are the parameters that you can use to test your MySQL Cluster deployment using the Severalnines Configurator.

In all cases, the Internal IP was used as the Hostname in the Configurator and the following was used for all tests:

* Instance type: m1.larg
* Number of instances: 5 (1 for ClusterControl), 2 for data nodes, 2 for MySQL servers and management servers.

RightImage_CentOS_5.4_x64_v5.5.9 (ami-0f42a966)

* Cloud Provider [Configurator]: Amazon EC2
* OS user [Configurator]: root
* Operating System [Configurator]: Redhat/Fedora/Centos/Oracle
* Data directories [Configurator]: /mnt/data/mysqlcluster for data nodes and management servers and /mnt/data/mysql (for the mysql servers) both RPM and tar.gz installation was tested using 'deploy.sh'

Canonical AMI: ubuntu-maverick-5g-64bit (ami-ac41b7c5)

* Cloud Provider [Configurator]: Amazon EC2
* OS user [Configurator]: ubuntu
* Operating System [Configurator]: Ubuntu/Debian
* DataMemory [Configurator]: 512MB
Set it down in the Configurator - yes, it is tiny, but the default disk in this AMI is tiny, so you should add a 20GB EBS Volume if you want to test with the default suggested DataMemory
* Data directories [Configurator]: default suggested ones.
* Installation was tested using 'deploy.sh'

Amazon QuickStart AMI: amzn-ami-2011.02.1.x86_64-ebs (ami-8e1fece7)

* Cloud Provider [Configurator]: Amazon EC2
* OS user [Configurator]: ec2-user
* Operating System [Configurator]: Redhat/Fedora/Centos/Oracle
* DataMemory [Configurator]: 512MB
Set it down in the Confgurator. Yes, it is tiny, but the default disk in this AMI is tiny, so you should add a 20GB EBS Volume if you want to test with the default suggested DataMemory.
* Data directories [Configurator]: default suggested ones.
* .tar.gz installation using 'deploy.sh' no problems.
* RPM installation - dependency problems with libmysqlclient.so.16 vs libmysqlclient.so.14.
This can be fixed by editing the mysqlcluster-71-rpm/cluster/scripts/install/install-rpm.sh before running 'deploy.sh':
Change this, in the function named install_rpm_cmonmysql() :
MySQL-Cluster-gpl-shared-compat-${version}-1.${rhel}.${arch}.rpm
to
MySQL-Cluster-gpl-shared-${version}-1.${rhel}.${arch}.rpm
Now you can run ./deploy.sh

Finally, do not forget to set the EC2 Keypair in the Configurator and upload it to the ClusterControl server before running deploy.sh.

You should now be up and running with your MySQL Cluster on EC2; if you have any questions or comments, please do let us know. We welcome your feedback on Facebook, Twitter, LinkedIn or directly on this blog.

MySQL Clusters in the Cloud with Severalnines on OpenShift

Tweet A blog post on how to deploy a sample JBoss application on OpenShift Flex - using a highly available, scalable backend that leverages MySQL Cluster

The Severalnines team has been busy during the summer months and as result, we have included OpenShift Flex support to our Severalnines Configurator (amongst other things). OpenShift, a Platform-as-a-Service operated by Red Hat, allows developers to develop and manage applications in the cloud. It is now possible to configure a clustered MySQL database for cloud services running on OpenShift. This brings high-availability and scalability at both the application and database layers.

As a guest contributor on Red Hat's OpenShift Community Blog, we provide a comprehensive, step-by-step walkthrough for this type of deployment. For those of you who would also like to view the process “in action”, feel free to view the video that complements this blog entry.
