Instance Types

(A, C, D, H, I, R, T, Z) refer to different families of instance types, each optimized for specific use cases

  1. A (General Purpose): - These instances provide a balance of compute, memory, and networking resources. They are suitable for a variety of workloads, including small and mid-sized databases, data processing tasks, and web servers.

  2. C (Compute Optimized):

    • These instances are designed for compute-intensive applications. They provide high-performance processors and are ideal for tasks such as high-performance web servers, batch processing, and scientific modeling.

  3. D (Dense Storage):

    • These instances are optimized for workloads that require high disk throughput and large amounts of storage. They are suitable for data warehousing, Hadoop distributed computing, and other data-intensive applications.

  4. H (High Memory):

    • These instances are optimized for memory-intensive applications. They provide a high ratio of memory to vCPUs and are ideal for in-memory databases, big data analytics, and high-performance computing (HPC) applications.

  5. I (I/O Optimized):

    • These instances are designed for applications that require high input/output operations per second (IOPS). They are suitable for NoSQL databases, data warehousing, and other applications that require fast access to large datasets.

  6. R (Memory Optimized):

    • These instances are optimized for memory-intensive applications, providing a high amount of RAM relative to vCPUs. They are ideal for applications such as in-memory databases, real-time big data analytics, and high-performance computing.

  7. T2/T3 (Burstable Performance):

    • These instances provide a baseline level of CPU performance with the ability to burst to higher levels when needed.
    • If the machine bursts, it uses burst credits -They are suitable for applications with variable workloads, such as web servers and development environments. If CPU credits are exhausted beyond the burst level, then the CPU performance will slow down to the baseline level. Cpu spike grahp

  8. U can setup the unilited but be cerfull

    • U pay extra money when over the credit balance
    • U pay for additional vCPU/h if the avarge cpu usage over 24h exceeds the baseline

  9. Z (High Performance Computing):

    • These instances are designed for high-performance computing applications that require significant computational power. They are suitable for workloads such as simulations, financial modeling, and scientific computing. — bash Ec2instance
