Case studies from global leaders on how Cirata resolved their Subversion challenges.

Remote developers latency problem
Problem
  • Remote developers experience significant latency and slowdowns when accessing the single Subversion repository located at their headquarters, hindering productivity and collaboration.
Solution
  • Deploy Subversion MultiSite Plus at locations geographically close to development teams to establish multiple active-active replicas of the repository across different locations.
Results
  • Remote developers experience dramatically faster response times, leading to increased productivity and improved collaboration.
  • The risk of downtime and data loss is minimized, providing peace of mind for the organization.
Disaster recovery solution with a large number of developers at a single site
Problem
  • A company with a large development team concentrated in a single location relies on a centralized Subversion server.
Solution
  • Implement Subversion MultiSite Plus to create offsite or cloud-based replicas of the repository data.
  • This offsite replica acts as a disaster recovery site, providing a readily available backup of the repository data.
Results
  • The risk of data loss is significantly reduced, protecting valuable intellectual property.
  • Developers can continue working with minimal interruption, even if the primary site becomes inaccessible.
3rd party in another geographical location to be able to access a subset of their data for collaboration
Problem
  • An organization needs to share a specific portion of their Subversion data with a third-party partner located in a different region.
Solution
  • Utilize the selective replication feature of Subversion MultiSite Plus to replicate only the required subset of data to a new site accessible to the third-party partner.
Results
  • The company achieves secure and efficient collaboration with its third-party partner.
  • Data synchronization issues are eliminated, ensuring everyone works with the latest information.
  • The main repository remains protected, with access limited to authorized personnel.

Features and benefits of Subversion MultiSite Plus

1. Automatic catch-up after offline events:

The Automatic catch-up feature of Subversion MultiSite Plus seamlessly syncs write operations during outages, eliminating manual repair efforts and maintaining business continuity to prevent lost productivity and data inconsistencies.

2. Fast local checkouts:

Fast local checkouts in Subversion ensure reduced wait times and enhanced performance, potentially boosting productivity by 3-5% per developer for geographically dispersed teams.

3. Disaster recovery:

Configuring a remote disaster recovery site with continuous synchronization minimizes data loss risk, ensures swift recovery, reduces downtime, and potentially saves significant costs by maintaining an up-to-date replica ready for immediate restoration after disasters.

4. Selective replication:

Selective replication optimizes storage utilization and reduces costs by replicating only necessary repositories, while ensuring regulatory compliance through precise control of data location.

5. Seamless scalability:

Seamless scalability allows for effortless addition of new nodes, offering flexibility to expand infrastructure with minimal downtime and enhanced operational efficiency, ensuring continued developer productivity.
