Amazon Elastic Compute Cloud: AWS EC2 is a web service having a feature of resizable compute in the cloud. It makes the process of web-scale computing easy for developers. This provides an interface, with which they can get configure capacity by minimum resistance.
Developers will be able to hold the entire control on their computing resources, and also it offers them to run on Amazon’s established computing environment. It helps in cutting down the time needed to boot advanced server instances to minimal and permits the capability to scale both up and down quickly as the computing necessities vary. Another remarkable significance is that it provides tools with the aid of which administrators and developers can be out of the fear of failure in case of tough applications and devoid themselves from other common failure scenarios.

Benefits AWS Compute
- Elastic Web-scale Computing: It is capable to make variations in capacity within minutes, by either enhancing or reducing it. We might use one or thousands of server instances concurrently since they are all controlled with web service APIs; the application belonging to us may automatically level itself up or down according to the requirements.
- Completely Controlled: Being a client, we have an intact control over all the instances of Amazon EC2. If we wish to retain data on our boot partition, then it allows us to stop the instance. Later, the instance can be restarted using the web service APIs, along with the access for the console output will be provided.
- Flexible Cloud Hosting Services: It will permit us to choose instance storage space, memory configuration, CPU, and boot partition sizes that are best for the applications and the system we have selected. For example, our selected OS contains several Linux distributions and Microsoft Windows Server 10. Moreover, Amazon provides resolution for query processing, computing, and storage among huge applications by adopting the components given below:
- Amazon S3 (Amazon Simple Storage Service)
- Amazon RDS (Amazon Relational Database)
- Amazon DynamoDB
- Amazon SQS (Amazon Simple Queue Service)
Let’s now check out the other major benefits of Amazon EC2.
- Reliable: Amazon is known for its reliability, especially when it comes to the replacement of instances. The service will be available within data centers and the network infrastructure. Further, AWS SLAs (service-level agreements) have promised that they will provide 99.95 percent availability for every region.
- Secure: It will facilitate security and robust networking operations for our computer property by adopting the component known as Amazon Virtual Private Cloud (VPC). The compute instances are placed within VPC by an IP address that we indicate. ACLs (access-control lists) permit to manage inbound and outbound network access. The present IT infrastructure can be connected to the resources within our VPC with the help of the industry-customary encrypted IPsec VPN connections.
- Inexpensive: Services provided by Amazon EC2 are inexpensive. The rate of the consumption of the compute power is more than the amount we pay for it.

The payment for the computing service can be done on an hourly basis with no long-term assurance. Thus, it helps us come out from the issues of purchasing, maintaining, and planning of hardware and replaces the usual huge preset costs with lesser erratic costs. With the aid of this, we can avoid the requirement for buying the ‘safety net’ capability to manage intermittent traffic spikes.
With the aid of reserved instances, it is possible to reserve the computing capacity for 1–3 years. The reserved instance marketplace can be used to sell reserved instances if our requirements get changed. For example, if we wish to shift to an innovative AWS region, then we switch to using a new instance form.
This is an instance that permits to tender on idle EC2 capacity and executes those instances until the bid beats the current spot cost. The spot value/cost varies sometimes depending on the supply and demand and on the clients whose tender reach or go beyond its gain access to the available spot instances. If we are aware when our applications are required to run, spot instances can be considerably lesser.
