Your organization has grown significantly, and the JIRA instance is struggling to handle the increased load. What solution should you consider to improve performance and scalability?

Implementing JIRA Data Center allows for horizontal scaling, distributing the load across multiple nodes. This enhances performance and scalability, accommodating the increased load efficiently. Upgrading hardware resources might provide temporary relief but won't address long-term scalability needs. Optimizing database performance and utilizing caching mechanisms can complement but aren't as comprehensive for scalability.
