Top Security Features in AWS Elastic Computing (Ec2)

You can call EC2 as Amazon Elastic Computing Cloud is EC2. This is a good interview question. The computing capacity has an elastic property. Based on your requirement you can increase or decrease computing power. I am giving in this AWS EC2 real story for your quick reference.

While you enable the Autoscaling feature, you need to know its impacts. Since it is the responsibility of the Administrator.

Amazon AWS EC2.

Making your existing hardware to the requirement always is not so easy. So the EC2 feature in AWS helps you to allocate computing power according to your needs. AWS EC2 instance acts as your physical server. It has a memory. 

You can increase the instance size in terms of CPU, Memory, Storage, and GPU. EC2 auto scaling is a property, where it automatically increase your computing power. 

AWS EC2 also called elastic computing cloud. In this post added the list of Security features present in EC2 cloud.

1. Security Features in EC2 

  • Virtual Private CloudThe responsibility of Virtual Private Cloud is to safeguard each instance separately. That means, you cannot access other instances, which are already created by other organizations.
  • Network Access Control List. It acts as a firewall to both incoming and outgoing requests.
  • Access Management. Control level of access granted to each user.
  • Security Groups. Each instance can have 5 security groups. It acts as a firewall. It is something more detailed over the Network Access Control List.
  • Hardware Security DeviceA security device, to control security between on-premise network hardware and AWS cloud hardware.

2. AWS EC2 or Elastic Computing Instance

  • The instance is one server virtual in nature created on behalf of an organization on the AWS cloud. You can find different AWS instances. Those are A1, T3, T2, M5, M5a, M4, etc.
  • Instance type means it has different combinations of computing power.

  2. CLI
  3. AWS SDKs

4. AWS Security Group

Each Security group associated with an instance. You can create a security group and define rules for that depending on the requirement.

How to learn about AWS EC2 is a big question for many developers. Some people read AWS EC2 tutorials, and some people learn from good AWS books. The best option is to first create one AWS free account and use your tutorials and books to elaborate more and to get more hands-on.

5. AWS Top Instance Types According to the wiki

  1. General Purpose: M5, M4, T2
  2. Compute Optimized: C5, C4
  3. Memory-Optimized: X1e, X1, R4
  4. Accelerated Computing: P3, P2, G3, F1
  5. Storage Optimized: H1, I3, D2

AWS EC2: Frequently Asked Questions  

1) When does EC2 introduce?

A) 2006

2) Does EC2 has a graphical user interface?

A) Yes, it has.

3). What are the real applications of EC2?

A) It is scalable and faster Docker container management features.

4). What is an instance?

A). The virtual computing power you can say as an instance.

5). What is an AMI?

A) This is a pre-configured template to use in an instance. 

6). What is AWS Lambda?

A). This is a compute service that runs code without the need to provision or manage servers.

7). What is AWS Elastic beanstalk?

A). This is a service that enables you to quickly deploy and manage applications on the AWS Cloud without worrying about the infrastructure that runs those applications

8). What is Amazon Light Sail?

A). This service is for developers who need virtual private servers. Amazon Lightsail includes everything you need to launch your project quickly—a virtual machine, SSD-based storage, data transfer, Domain Name System (DNS) management, and a static IP address—for a low, predictable price.

9). What is AWS Batch?

A). This service enables you to run batch computing workloads on the AWS Cloud. Batch computing is a common way for developers, scientists, and engineers to access large amounts of computing resources

10). What is Amazon EBS volume?

A). The persistent storage volumes for your data using Amazon Elastic Block Store (Amazon EBS), known as Amazon EBS volumes

aws Iaas leader in the market

11). What is an Elastic IP address?

A). The IP Address, which is assigned to an instance is called Elastic IP Address.

12). What is Amazon Virtual Private Networks?

A). Virtual networks that you can create that are logically isolated from the rest of the AWS Cloud and that you can optionally connect to your own network.

13). What is Amazon AMI?

A). An AMI provides the information required to launch an instance.

14). How many ways you will get AMI? and what are those methods?

A). You will get by 4 methods.
Those are:
  1. Provided by AWS
  2. AWS Marketplace
  3. You can create and manage your own AMIs.
  4. A shared AMI
 15). What is Shared AMI?

A). A shared AMI is an AMI that a developer created and made available for other developers to use.

**Note: The Amazon ECS. You can call it Amazon Container Service. You can manage Docker containers on Amazon ECS
