Q & A

What are the different types of instance types available when launching an instance?

There are 559 different instance types available, which are constantly increasing. The key instance types include general purpose, compute-optimized, memory-optimized, accelerated computing, and storage-optimized.

What does 'T2 Micro' represent in the instance types?

'T' represents the class of the instance, '2' represents the generation, and 'Micro' refers to the size of the instance. As new generations are released, the number will increase, such as T3, T4, etc.

How do the instance sizes vary, and what are some examples?

Instance sizes vary from smallest to largest, starting with Nano, followed by Micro, Small, Medium, Large, X-Large, and 2X-Large. These sizes depend on the resources like CPU and memory.

How should you choose the right instance type for your application?

Choosing the right instance type depends on your application’s requirements. For example, general-purpose instances are suitable when the workload has a balance between memory, CPU, and networking. Compute-optimized instances are ideal for tasks requiring high CPU performance, like media processing or machine learning.

What is the significance of memory-optimized instances?

Memory-optimized instances are used when an application requires a large amount of memory, such as in-memory databases, caching, or high-memory operations. They are ideal for workloads that involve heavy memory usage.

When should you use compute-optimized instances?

Compute-optimized instances should be used when you need high CPU performance, such as for running media processing tasks, generating a large number of PDFs, or operating high-performance web servers.

What are accelerated computing instances used for?

Accelerated computing instances are primarily used for graphics-intensive applications or tasks requiring GPU processing, such as machine learning, 3D rendering, or simulations.

When should storage-optimized instances be used?

Storage-optimized instances should be used when an application requires high disk throughput and fast data retrieval or storage, such as in distributed file systems, databases, or data warehousing applications.

What is the importance of load testing after selecting an instance type?

It is crucial to perform load testing after selecting an instance type to ensure that the server can handle the expected number of concurrent users. Various tools are available in the market to carry out load testing.

What is a general-purpose instance, and when should it be used?

A general-purpose instance balances CPU, memory, and networking resources. It should be used when the application’s resource requirements are balanced and do not heavily focus on any single resource like CPU or memory.
