Description: Burst instances are a type of cloud computing resource designed to handle temporary spikes in traffic and workload. These instances allow users to take advantage of additional performance during periods of high demand without needing to maintain a constant level of resources that could be costly. Their operation is based on a credit model, where instances accumulate CPU credits when idle and use them when higher performance is required. This makes them an ideal option for applications with variable workloads, such as websites, mobile applications, and online services that experience traffic fluctuations. Burst instances are especially relevant in cloud environments, where scalability and cost efficiency are paramount. By allowing users to dynamically adjust their resources, these instances contribute to more effective cost management and a better user experience, ensuring that applications remain fast and responsive even during activity spikes.
Uses: Burst instances are primarily used in applications that experience variations in workload, such as e-commerce websites, streaming platforms, and mobile applications. They are ideal for environments where traffic spikes are unpredictable, allowing businesses to scale their resources efficiently and cost-effectively. They are also used in testing and development, where developers may need additional resources temporarily to conduct load testing or implement new features.
Examples: A practical example of burst instances is the use of cloud services such as Amazon EC2 T2 or T3, which allow users to automatically scale their CPU resources based on demand. Another application is in online gaming platforms, where the number of players can suddenly increase during special events, requiring a temporary boost in processing capacity.
