Solutions for Subversion

Absolutely! Cirata's MultiSite solutions are designed to operate seamlessly in both public and private cloud environments. This gives you the freedom to choose the deployment model that best aligns with your infrastructure strategy, security requirements, and budget.

No matter where you choose to deploy, you'll enjoy the same benefits of enhanced global collaboration, low-latency performance, and robust fault tolerance.

Latency can severely hinder engineering productivity, especially when dealing with large codebases and distributed teams. The TCP protocol, which underpins most internet communication, is inherently limited by latency. Higher latency directly translates to lower effective bandwidth, regardless of your theoretical connection speed.

Imagine a common scenario: a developer in the US needs to check out a 500MB repository located in India. With a typical latency of 330ms, this seemingly simple operation could take around 30 minutes! That's half an hour of unproductive waiting. In contrast, the same checkout on a local network with minimal latency would be completed in seconds.

This disparity highlights the hidden cost of latency: countless hours wasted waiting for operations to complete, instead of engineers actively contributing to projects.

By strategically replicating your repositories closer to your development teams, Cirata drastically reduces latency. This translates to faster checkouts, updates, and overall improved responsiveness, empowering your engineers to focus on what they do best: building great software. The resulting boost in productivity can lead to a significant return on investment, making Cirata a compelling solution for globally distributed teams.

Alternative methods often involve "read-only" repositories that forward all write operations to a central site. This central site becomes a single point of failure; if it’s inaccessible, remote sites cannot update, and if it fails, there’s no guarantee which copy has the latest data.

Cirata’s DConE implementation offers a superior solution through true multi-primary replication. Here’s how it works and its benefits:

Unlike traditional methods, Cirata’s DConE ensures that updates are coordinated across multiple primary servers. This eliminates the single point of failure and ensures data consistency across all sites.

Before an update is made, the Content Delivery Policy is satisfied to ensure data integrity. DConE then coordinates a vote among the replicas and schedules the update in a globally unique order.

Each replica executes updates in the same globally unique order, ensuring all sites have the latest data. The Git MultiSite UI provides visibility into the update state, so you always know which replicas have the complete set of updates.

By distributing write operations and coordinating updates across multiple sites, DConE enhances system reliability and availability, even in the event of site failures.

End-users benefit from faster access to data without the latency and downtime risks associated with a single central repository.

These features make Cirata’s DConE implementation a robust and reliable choice for distributed development environments.

Our experienced Professional Services Team will guide you through a seamless deployment process:

• Testing and validation: We'll conduct thorough testing to ensure everything is functioning optimally before going live.
• Knowledge transfer: We'll provide documentation and guidance to upskill your team on product administration, ensuring you have the expertise to manage and maintain your MultiSite environment effectively.
• Ongoing support: We'll provide continued support and assistance as you transition to your new MultiSite environment.

MSP (especially when combined with ACP) provides several ways to protect data both at rest and in flight. Data is protected by the standard SVN authentication and authorization methods to ensure that it cannot be accessed by anyone who has not been granted access. Data in flight can be protected by configuring SSL, after which all communication between sites will be fully encrypted. MSP also provides the flexibility to replicate only a subset of repositories to any given node, thus ensuring that sites do not contain data that is not required by teams operating out of that site.

Organizations use Subversion (SVN) to version control various types of files, particularly those that are crucial for collaborative development and tracking changes over time. These file types generally include:

• Source Code Files:
  • Programming languages: Files like .java, .py, .cpp, .js, .html, .css, etc., are commonly tracked in software development.
  • Scripts: Shell scripts (.sh), batch files (.bat), or other automation scripts can be version-controlled.
• Configuration Files: Files that configure software environments or applications, such as .xml, .json, .ini, .yml, or .properties files, are commonly versioned.
• Documentation:
  • Text and Markdown files: Files like .txt or .md are often versioned to document software projects or other internal processes.
  • User manuals and guides: These could be in formats like .pdf or .docx, although binary files are less ideal for version control compared to text files.
• Project Management Files: Files like build scripts (makefile, pom.xml, build.gradle), task lists, or project plans are versioned to track changes in the project setup.
• Binary Files: Some organizations version-control files such as:
  • Design assets: Images (.png, .jpg), videos (.mp4), or audio (.wav) files.
  • Compiled binaries: .jar, .dll, or .exe files are sometimes versioned, although it's more common to version the source code.
• Database Scripts: SQL files (.sql) or database migration files that define database schemas or data transformations.
• Test Files: Test data, scripts, or automation code used for testing software, such as unit test code (.test, .spec), or test input data in .json, .csv, .elf or .xml.
• Web Assets: Organizations involved in web development or with a heavy web presence may version-control HTML, CSS, JavaScript, and static assets like fonts or icons.

Overall, files under version control are files that are modified and need to be tracked for historical changes, collaboration, or rollbacks. Subversion is effective for keeping track of changes in both text-based and binary files.
