Different Type of EC2 And Their Requirement

Hi Guys, I am overwhelmed with joy by the way the first blog was received and it motived me to continue blogging. Today’s topics will be Different types of EC2 and their requirement. There is 2 thing one is different way to launch ec2 instances and second is different type of ec2 instances. So, Lets get started.

DIFFERENT WAY TO LAUNCH EC2 INSTANCES-Amazon provides different ways to pay for the EC2 instances

• On-Demand Instances
• Reserved Instances
• Spot Instances
• Dedicated Hosts
• Dedicated Instances

On-Demand Instances- With On-Demand Instances, you pay for compute capacity by the second with no long-term commitments. You have full control over its lifecycle — you decide when to launch, stop, hibernate, start, reboot, or terminate it. There is no long-term commitment required when you purchase On-Demand Instances.

Reserved Instances-Reserved instances is a discount billing concept in which business can obtain significant discounts compared to standard “On Demand” cloud computing prices in return for committing to a specified level of usage. However, the terms under which a Reserved Instances discount is offered vary from provider to provider

Spot Instances-A Spot Instance is an unused EC2 instance that is available for less than the On-Demand price. Because Spot Instances enable you to request unused EC2 instances at steep discounts, you can lower your Amazon EC2 costs significantly. The hourly price for a Spot Instance is called a Spot price.

Dedicated Hosts-An Amazon EC2 Dedicated Host is a physical server fully dedicated for your use, so you can help address corporate compliance requirements. … Use AWS License Manager to start managing your Dedicated Hosts.

Dedicated Instances-Dedicated Instances are Amazon EC2 instances that run in a VPC on hardware that’s dedicated to a single customer. Your Dedicated instances are physically isolated at the host hardware level from instances that belong to other AWS accounts.

DIFFERENT TYPE OF EC2 instances come in the following categories:

• General Purpose: The most popular; used for web servers, development environments, etc.
• Compute Optimized: Good for compute-intensive applications such as some scientific modelling or high-performance web servers.
• Memory Optimized: Used for anything that needs memory-intensive applications, such as real-time big data analytics, or running Hadoop or Spark.
• Accelerated Computing: Include additional hardware (GPUs, FPGAs) to provide massive amounts of parallel processing for tasks such as graphics processing.
• Storage Optimized: Ideal for tasks that require huge amounts of storage, specifically with sequential read-writes, such as log processing.

Details by EC2 Instance Type

Type: General Purpose

General Purpose instances are the most widely used and are a good first step if you’re new to AWS or cloud computing in general. They offer a great mix of cost and functionality, with their typical use being geared towards web servers, running development environments for your mobile or gaming apps, and running enterprise applications such as CRMs and ERPs. You’ll find that one of the main distinctions within this class is between instances with Fixed vs. Burstable performance. With Burstable performance EC2s, you’ll have the ability to quickly scale up your compute power — at a price.

General Purpose: A1

A1 instances are general use but differentiate themselves by being an ARM-based offering, as opposed to Intel or AMD. As such, this platform will appeal more to the ARM development community and to applications that already run open source software such as Java and Python and the multiple architectures these tend to support.

General Purpose: M5

M5 instances run on Intel Xeon processors and are thus suited to developing on the x86 architecture. They offer higher compute, memory, and network performance when compared to the A1.

M5 instances are great for development and test environments as well as web servers. They also offer support for Intel AVX-512, a set of CPU instructions that benefits the processing of encryption algorithms, so these instances are a great choice when security is important while not affecting performance.

General Purpose: T3 and T3a

T3 and T3a are respectively the Intel and AMD offerings of Burstable performance instances. Burstable performance instances are great if you want a cheaper and slightly less powerful offering than a fixed performance instance (like an M5), but you still want the option to be able to scale up your compute quickly to handle workloads, hence the “bursts” in power.

These bursts of power don’t come for free — they’re handled by CPU credits. In general, when you are not running at maximum processing power, you earn CPU credits. The amount you earn depends on the time at a low threshold and the size of your instance. When you need to burst up, these credits are spent.

Type: Compute Optimized

Compute Optimized: C5

C5 instances are ideal for applications where you prioritize raw compute power, such as gaming servers, scientific modeling, high-performance web servers, and media transcoding. C5 instances run on Intel Xeon Platinum processors and are benchmarked at 25% faster than previous-generation C4 instances — a clear example of the benefits of generational improvement in cloud resources.

Type: Memory Optimized

Memory Optimized: R5 & R5a

R5 and R5a are respectively the Intel and AMD offerings of “regular” memory optimized instances. These instances are ideal for memory intensive applications such as real-time big data analytics, large in-memory caches, and high-performance databases. The R5 and R5a instances benefit from the AWS Nitro System, which gives you access to almost all of the compute and memory resources of a server (i.e. allocating as little as possible to the OS). This optimization allows for lower cost when compared on a per-GiB basis to competitors.

Memory Optimized: X1 & X1e

X1 and X1e instances are optimized to provide a high ratio of memory to compute with the X1e family delivering the highest memory to compute ratio among EC2 offerings. These instances are used for the highest need memory-intensive applications such as SAP HANA, providing a strong foundation for real-time applications.

Memory Optimized: High Memory instances

High Memory instances have the greatest amount of available RAM, providing 6 TB, 9 TB, or 12 TB of memory in a single instance. Like X1/X1e, these are suited to production deployments of hugely memory intensive, real-time databases such as SAP HANA.

An important caveat with High Memory instances is that they are only available on Dedicated Hosts on a 3-year Reservation. This means that you will need to commit to a 3-year purchase, but you will get the security benefit of being on a host that is dedicated, i.e. you’ll have your own server to yourself and will not share resources as AWS does with other offerings.

Type: Accelerated Computing

Accelerated Computing: P3, G3, F1

Accelerated Computing instances use separate Graphical Processing Units (GPUs) or Field Programmable Gate Arrays (FPGAs) to optimize for specialized tasks such as graphics processing or floating-point number calculations. The instance offerings are:

• P3: These are the general GPU offerings, good for machine learning and offering robust parallel processing abilities.
• G3: These are the GPU offerings that are specialized for graphics-intensive tasks such as rendering, encoding, and streaming.
• F1: These are instances that offer FPGAs for accelerated processing. You can leverage the FPGAs multiple ways over time for different enhancements, and all this is aided by custom FPGA-specific AMIs (called AFIs) that offer quicker deployment and development options compared to conventional FPGAs.

Type: Storage Optimized

Storage Optimized: H1 & D2

H1 and D2 instances are part of the Dense storage offerings that provide high sequential read-writes for large data sets, such as in distributed Hadoop deployments. H1 and D2 instances provide immense storage on HDD, with H1 providing a maximum of 16 TB and D2 providing a maximum of 48 TB.

Storage Optimized: I3

I3 instances offer storage on SSD with a maximum of just under 16 GiB. However, these instances provide lower latency than HDD-based storage and also offer AWS Nitro System for optimized access to memory and computer resources (also called “Bare Metal” access).
