Instance Types Amazon – An AWS EC2 instance needs to support workloads from web server to FPGA and even HPC.
You have 350 different AWS EC2 instances in 2021. Choosing the right AWS EC2 instance from these large stacks is difficult.
In this article, you’ll learn how to choose the right AWS EC2 instance without breaking your budget. You will also learn about the different types of AWS EC2 instances.
If you are working for an AWS certificate. You will also learn about AWS EC2 instance naming conventions. What AWS decides about the instance size. It will also help you understand the different types of examples and create that house in your mind. This is by far the best way to remember different AWS EC2 instance names.
Is the current generation. The latest (current) generation of an AWS EC2 instance is always better than the previous generation.
The m5.large EC2 Savings Plan costs $0.06 per year, no upfront cost in the US East (OH) region. 1-year, no upfront EC2 Instance Savings Plan fee of $0.062 for m4.large in the US East (OH) region
To use older generation AWS EC2. With this in mind, always choose the latest generation equipment.
Each instance size (xLarge) has twice the CPU, memory and storage resources of the previous size (Large). Hurry to find out how.
The picture below will help you understand this concept. Each instance size (xlarge) has twice the CPU and memory of the previous size (large).
Don’t believe the image above, you can talk about data, use the AWS EC2 pricing calculator. This helped create the following table.
Service load is not linear, it is a curve. This is not taken into account in the multiplication above.
If you remember the Bresenham line drawing algorithm. Describes how to draw a line with square pixels.
The line can be smooth only if you have lots of dense pixels. If you have a very detailed AWS EC2 instance size, an AWS EC2 instance may experience uneven load.
It is always better to use a smaller sample size. Use a larger sample size if you have a specific need.
The figure below shows the relationships between different types of AWS instances. The alphabet is written on a green background. Declares the instance family value in AWS EC2 naming conventions.
You focus only on the name of the classification and subclassing. Details of these classifications will be given later.
The body of the task instance provides the root of the above classification. The web server may use a general purpose instance. These examples are suitable for everyday work.
The most common and versatile AWS EC2 instances are general purpose instances. They provide an ideal balance between computing resources, memory and network resources. The picture below shows the highlights of both subclasses of the general purpose example.
T3/T4g has a base CPU performance of 2.5 GHz. These instances can achieve higher performance in less time. So T3/T4g is an example for extrusion.
This explosion pays off with CPU points. When an instance is idle, it causes CPU credits to accumulate.
For t3.large in the US East (OH) region, the 1-year no-upfront EC2 Instance Savings Plan fee is $0.0522.
For t4g.large in the US East (OH) region, the no-upfront 1-year EC2 Instance Savings Plan fee is $0.0421.
This is a more stable sample compared to the T2/T4a sample. They use an Intel 3.1 GHz processor. Should be the first choice for anyone starting AWS. These cases offer better entry-level performance.
For m5.large in the US East (OH) region, the 1-year no-charge EC2 Instance Savings Plan fee is $0.06.
AWS EC2 now offers macOS as a development option. These are based on the Apple Mac Mini computer. It uses an Intel Core I7 processor with 3.2 GHz (4.6 GHz Turbo) performance. just there
For a1.large in the US East (OH) region, the fee for a 1-year EC2 Sample Savings Plan without prepayment is $0.0321.
Other ARM and Mac instances are very specific. In these cases, you should use it until you have a special need.
The server you want to use to increase computing power. They support processing power from 3.6 GHz to 3.9 GHz.
For c5.large in the US East (OH) region, the 1-year no upfront EC2 Sample Savings Plan rate is $0.054.
RAM directly affects all computing operations. If you need more RAM you should use these examples. They support the 4.0 GHz computing frequency. The base instance has 16 GiB of RAM. It is more than a computing and universal example.
This is an example of a regularly higher RAM. They provide more RAM per vCPU. 768 GiB is the maximum available RAM.
For r5.large in the US East (OH) region, the fee for the 1-year non-prepaid EC2 Instance Savings Plan is $0.079.
US East (OH) EC2 x1.16xlarge instance savings plan costs $4.11, 1-year no upfront
These are examples that support high computing power and large memory. The computing power is 4.0 GHz. It also supports NVMe SSDs for lower I/O latency and more RAM from 16 GiB to 384 GiB.
For z1d.large in the US East (OH) region, the fee for a 1-year non-prepaid EC2 Instance Savings Plan is $0.117.
No upfront 1-year EC2 instance savings plan rate for d3.xlarge in the US East (OH) region is $0.315.
High IO requires the power of an NVMe SSD. Because these enclosures support NVMe SSDs. You can get very low latency.
For i3.large in the US East (OH) region, the no-upfront 1-year EC2 Savings plan rate is $0.107.
These instances support 16TB of local hard disk storage. Because the storage is local, latency is very low.
In the US East (OH) region, the h1.2xlarge rate of the 1-year EC2 Sample Savings Plan with no prepayment is $0.318.
Until now, all sample types used similar equipment. No special equipment was used to increase efficiency. The Accelerated Computing example changes that. It uses special equipment for certain tasks. As a GPU for GPU-intensive and parallel processing.
P samples are also called parallel samples. These situations are best suited for machine learning and HPC. There are many NICs in these cases.
For p4d.24xlarge in the US East (OH) region, the fee for the 1-year non-prepaid EC2 Instance Savings Plan is $20.1754983.
For g3s.xlarge in the US East (OH) region, the no-upfront 1-year EC2 Instance Savings Plan fee is $0.551.
For inf1.xlarge in the US East (OH) region, the 1-year no upfront EC2 Instance Savings Plan rate is $0.232.
AWS provides a very good tool called AWS Instance Type Explorer. This will help you choose the type of sample you want.
When you submit a request using these four options. This tool will suggest some sample types to use. As for the above combination, the proposal came as follows.
But he did not suggest a size. If you get an instance type class like now. It is always better to start with the smallest size. Run tests with on-demand instances and then size.
AWS EC2 has a great naming convention. It’s not a very good documentary though. The naming convention above comes from a rethinking of video and common sense. The more you look at the title, the more confusing it seems at first. If you can weed out the noise, you might notice a hidden pattern called AWS EC2 instance.
The most important thing is to understand the four main classifications. How is the server used differently?
The five causes listed above form the classification by type of manifestation. Whether optimized for memory or optimized for operation. As I said, you need to remove the noise to find the pattern.
When you understand the basic classification. Subclassing can be natural. As with memory optimization,
AWS instances are divided into categories and subcategories for a reason. Try your own understanding to find a pattern. This will help you remember the details.
Finally, when you decide on the subject. You should always choose a smaller sample to try. Determine actual sample size based on experiment. As a general rule always go for the smaller size, it will save you money.
I hope you understand the concept of AMI. If you want to start an EC2 instance. Checkout, EC2 free tier release article. See step-by-step instructions for creating an EC2 instance. Amazon Elastic Compute Cloud (Amazon EC2) is a web service
