10 Questions
What is vertical scaling, and what does it involve?
Vertical scaling, also known as 'scaling up', is a method for boosting a system's capacity by adding more resources to the existing machine, which can involve upgrading components like the CPU, memory, storage, or network card.
What are some scenarios where vertical scaling might be a good choice?
Vertical scaling is suitable for simple workloads, starting out, internal systems, and limited downtime.
What are the limitations of vertical scaling?
The limitations of vertical scaling are cost, single point of failure, and limited scalability.
Why is horizontal scaling often preferred for large-scale applications?
Horizontal scaling is often preferred for large-scale applications because it can distribute the workload across multiple machines, making it more scalable and less prone to downtime.
What is the main difference between vertical scaling and horizontal scaling?
Vertical scaling involves adding more resources to the existing machine, while horizontal scaling involves adding more machines to distribute the workload.
What is horizontal scaling, and how does it differ from vertical scaling?
Horizontal scaling, also known as 'scaling out', involves adding more machines (nodes) to distribute the workload, whereas vertical scaling involves upgrading a single machine.
How does load balancing contribute to the effectiveness of horizontal scaling?
Load balancing ensures that incoming requests are distributed across multiple machines, preventing any single machine from getting overloaded.
What are some advantages of horizontal scaling?
Horizontal scaling offers high availability, elasticity, and cost-effectiveness, making it ideal for cloud-based applications.
What is the main benefit of using multiple machines in horizontal scaling?
The main benefit is increased processing power, storage capacity, and throughput, which can be scaled up or down as needed.
What are some challenges associated with horizontal scaling?
Horizontal scaling can introduce complexity in managing a cluster of machines, and network overhead due to communication between machines.
Learn about vertical scaling, a method to increase system capacity by adding more resources to existing machines. Understand scenarios where it's a good choice, such as simple workloads and starting out. Discover how to boost system capacity effectively.
