New Euro Partnership offers safe-haven from US Patriot Act

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, 23rd 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

Stockholm – October 25th 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.
