A.3. Instances are virtual environments provided by EC2 also known as EC2 Instances that can be used to host applications by cloud users. Following are the types of Instances available in Amazon EC2:
  • General Purpose: These instances equalize compute, memory, and networking resources and are ideal for applications that use these resources proportionately, such as web servers and code repositories.
  • Compute Optimized: These instances benefit from high-performance processors and are suitable for compute-bound applications like gaming servers, ad server engines, and compute-intensive applications.
  • Memory-Optimized: These instances are ideal for workloads that require the processing of large data sets in memory.
  • Accelerated Computing: These instances use hardware accelerators, or co-processors, to perform functions, such as calculations, graphics processing, data pattern matching, and others.
  • Storage Optimized: These instances are widely used to process workloads that require high, sequential read and write access to large data sets on local storage.

Q.4. What are the security best practices of Amazon EC2?

A.4. Following are the security best practices offered by Amazon EC2:

  • Amazon EC2 offers an IAM web service that helps regulate access to AWS resources.
  • With Amazon EC2, access to resources can be restricted by allowing trusted hosts the authority to access ports.
  • Amazon EC2 gives you the user authority to open only the required permissions.
