EC2 instance 101 : Launch your first Amazon EC2 instance Today

It's no surprise that AWS services over 190 countries, since it controls over 32% of the global public cloud market and offers highly scalable, dependable, and cost-effective infrastructure. Amazon EC2 is one of the company's most powerful and widely utilized services.

As a service accessible via the AWS cloud, Amazon EC2 offers a scalable pool of computer resources. When used, businesses may save money on hardware costs and speed up the creation and rollout of new software.

From a single location, users can start up virtual servers, set up networking and security, and even manage their cookies.

Connecting the service to AWS cloud storage through a web-based user interface. It gives users the tools they need to manage their own computing resources and work in the most efficient way possible by giving them safe and scalable computing tools. 

It is a cloud computing service that can be scaled up or down on demand, and Amazon is the main company that offers it. Without any due, let’s discuss what Amazon EC2 Instance is, its uses, types, and much more. 

What is an Amazon EC2 Instance and What Does the EC2 Stand For?

Amazon EC2 stands for Amazon Elastic Compute Cloud. Amazon EC2 is the core service for computing in a web service that belongs to the compute domain of AWS.

An EC2 instance is effectively a virtual server that you "rent,” meaning you only pay for what you use. It gives secure computing capacity that can be measured or graded according to a scale.

EC2 consumers can use it to launch as many or as few virtual servers to manage storage and networking. An Amazon web service customer can help scale up or down the instance capacity using the EC2 web interface. Along with computing, it has all the services and allows the users to configure as per requirements.

The user can even exterminate the virtual device once it is no longer needed.  EC2 can be easily integrated with other services like S3 & RDS.

What are the Main Uses of the EC2 Instances?

EC2 services work amazingly without any problem with these things, and you can just focus on the development work, hence the cost here to manage the development and growth of the app. 

A section has been added. Amazon EC2 users can use it to launch as many or as few virtual servers, manage storage and configure the networking.

Organizations spend a lot of money buying hardware components, and managing them is more difficult than buying them, so EC2 Amazon eliminates the upfront investment in hardware so you can deploy applications faster. 

What are Amazon EC2 Instance Types and What Do They Offer?

Amazon EC2 Instance has different types that offer different perks. The following are the types of Amazon EC2 Instances: 

  1. 1

    Accelerate Computing Instance

    A hardware coprocessor/accelerator is a computing component that can speed up data processing. Normally coprocessors can be used for specific operations more efficiently than all other software running on CPUs, e.g., data pattern matching, number computation, graphics processing, etc.

    Whether the application uses floating-point calculations or graphics processing, accelerated computing instances will be best. Furthermore, using this instance-type data, pattern matching can be done more effectively.

  2. 2

    Compute-Optimized Instance

    Compute-optimized instances are suitable for applications requiring much computation and support from CPUs with the best performance. Compute-optimized instances are mostly used for workloads including application, web, and gaming servers in the same way as general-purpose instances.

    The applications that require high server performance for efficient work will be more beneficial from compute-optimized instances.

  3. 3

    Memory-Optimized Instances

    Memory-optimized instances are designed for workloads that require large data sets to proceed in the memory. Memory defines RAM, which allows us to do multiple tasks at once.

    It helps with storing instructions and data, which is important for the central processing unit to perform a test. Before a computer program or application can be run, it must be loaded from the storage into memory.

    This preloading process is very useful for providing direct access to a computer program. Suppose you have a workload that needs to preload a significant amount of data before performing an application.

  4. 4

    General Purpose Instances

    General purpose instances have balanced computing, networking resources & memory. You can use it for small databases and personal projects etc.

    Suppose you have an application with similar memory, computing, and networking requirements. Since the program doesn't require optimization in a specific resources area, you can use this type of EC2 to execute it.

    All the applications that require storage, networking performance, or want a bit of everything can use them for general purposes. If your applications don't require high-performance CPUs, you can go for general purpose ones.

  5. 5

    Storage Optimized Instances

    Storage-optimized instances are designed for workloads that require high, sequential read and write access to very large data sets on local storage. They are optimized to deliver tens of thousands of low-latency, random I/O operations per second (IOPS) to applications.

    Applications that prefer high database processing may use storage-optimized instances. Data warehousing applications or distributed file systems can use it.

How to Choose the Best Amazon EC2 Instance Type for Your Needs?

You can easily choose the appropriate type of instance for your needs by considering the number of CPU cores, storage systems, amount of system memory (RAM), and operating system.

According to the storage and workloads, the type of instance storage optimized would be the best Amazon type. It provides optimal storage capabilities for Amazon instances.

  • Select Instance Type 

    One of the most important decisions is choosing between compute-optimized, general-purpose, storage-optimized, and memory-optimized. Every subsequent decision will be made by him.

    Here, the decision you're making is primarily one of cost. The most important to your workload is you are trying to optimize the lowest dollar memory-optimized of the matrix.

    If your workload is compute-intensive, choose a compute-optimized instance type. If your workload is general, such as a web server, go with the general-purpose instance. If your workload is storage memory intensive the same logic applies.

  • Select Instance Family 

    For choosing the right instance it is important to look at the technical documentation for the application you plan to run. Remember that the number after the instance documentation is just the generation of the instance and the newest is usually the largest. 

  • Choose an Example with Special Features

     Do this only if necessary. You will pay extra for this.

  • Select an Instance Size 

    It is usually an iterative process and specified to your workload. You can perform this when you monitor the memory usage and CPU to see if the size of your choice is appropriate.

    You may need to. Choose a larger instance, if the workload is consuming an average of 90% of memory and CPU. You need to provide some headroom to prevent any performance issues from arising during periods of high demand. 

Tips for Optimizing Your Use of Amazon EC2 Instances for Your Business?

The following are some tips to follow for optimizing your use of Amazon EC2 Instance:

  • Buy a savings plan for effective capacity.

  • Identify and remove unused instances.

  • Verify that the instance types still reflect the current workload.

  • Verify that the maximum I/O performance of the instance matches the EBS volume.

  • Use Spot Instances for stateless and non-productive workloads.

Amazon web services provide us with a huge number of automation tools and analytics to help out Amazon streamline analysis. Identifying, curtailing, and deleting underutilized or unused instances can help save a lot of storage and, of course, cost. 

You can use the data provided by various management tools to identify used instances and downgrade them to a more common instance or, better yet, delete them if they are essentially useless. This will provide nice cost savings for your AWS EC2 Instance.


Elastic compute cloud is an Amazon web service that is popular among all users because of its quick installation. It provides the facility for users to infrastructure computing at very low costs.

EC2 Instance lets users easily scale up and down capacity over long periods and has many tools to protect data privacy. It provides resizable computing capacity in the cloud. It gives you full control of your computing resources and lets you run on Amazon's proven computing environment.


What are the instance, families?

There are four main families for the computing instances type that is accelerated computing p, G, F, and infl1. Accelerated computing is the type of instance that provides the best storage, high-performance, CPU, and networking options. 

What are the EC2 instance sizes?

There are many sizes of ec2 instance: Micro, Small, Medium, Large, Xlarge and 2Xlarge.
