Your organization is experiencing rapid growth and expects a significant increase in online transaction volume over the next year. As a security professional assessing the infrastructure to accommodate future demands, which of the following would be the BEST measure to ensure the infrastructure can scale securely and effectively?
Consolidate all data storage into a single geographic region to reduce complexity and ensure all users access the same resources.
Invest in a more powerful server to replace the current one, ensuring that the new hardware can handle the anticipated load for the next year.
Vertically scale the existing infrastructure by upgrading the current server to a model with more processing power and memory.
Plan for horizontal scaling by adding additional servers or utilizing cloud-based resources to distribute the load evenly across multiple hardware platforms.
Implementing scalability in the infrastructure planning ensures that the system can handle growth in user demand without performance degradation or security compromise. Vertical scaling might offer an immediate increase in resources but often leads to downtime during upgrades and has limitations on how much can be scaled up. On the other hand, selecting a more powerful server might provide temporary relief but doesn't provide a long-term scalable solution. Using a single geographic region for data storage may reduce complexity but doesn't consider the increased load that comes with growth. Horizontal scaling, which involves adding more servers or using cloud resources, offers flexibility, improved fault tolerance, and seamless scalability, making it the most effective option for sustained growth.
