Use Cases and Deployment Scope

Amazon EC2 auto scaling is used to make it possible for an application to remain available at least 99.99% of the time. This is made possible through ec2 auto scaling service, which automatically provisions new EC2 instances within seconds when existing instances crash or become unhealthy. The process is seamless and transparent to end users, who remain unaware of any background activity or disruptions.

Pros

Automated provisioning of EC2 instances in seconds.
End User activity not disrupted.
Limited to no notable downtime.

Cons

Enable cross region auto-scaling. It currently limited to a single region.
Support custom health check scripts, deeper integration with application-level metrics. At present, health checks are basic.
Adding cost-aware scaling scripts that factor in instance pricing and recommend optimal configurations based on budget constraints.

Return on Investment

Has helped increase service availability, which has contributed to a positive NPS from customers, leading to businesses maintaining current customers and enrolling more customers.
Has enabled businesses to deploy applications quickly that contribute to improved customer service.
Engineers can now focus more on product development rather than infrastructure issues.

Use Cases and Deployment Scope

In our organization, we use Amazon EC2 Auto Scaling to automatically adjust compute capacity based on workload demand for our product, scaling out during peak usage and scaling in during off-hours to save costs is the main purpose. Our use case primarily covers backend application servers, data processing workloads, and batch jobs that have fluctuating demand. It also integrates seamlessly with our Elastic Load Balancer.

Pros

Intelligently adds or removes instances based on traffic or workload metrics.
Eg: During business hours, our customer portal experiences high traffic.

Cons

Complex Initial Setup and Configuration
CloudWatch alarms require several interconnected steps. A more guided, visual setup workflow or better default templates could make onboarding easier.

Return on Investment

One of the biggest advantages we’ve seen is the reduction in infrastructure costs.
The setup phase required a significant time investment.

Use Cases and Deployment Scope

Sometimes, you start by configuring a server with the smallest configuration, but I think it is good to be able to find the one that suits your needs in the AWS market and simplify the server configuration procedure. There are so many virtual appliances that you can't choose. Because the infrastructure is handled by AWS, services may be put on the network without the need for networking skills. The greatest advantage is that users may concentrate just on programs.

Pros

Recovery time is surprisingly fast.
It is always used as a preference in conversations with other engineers.
Compared to other IaaS, the scale is different.

Cons

For newcomers, it might be a little confusing.
The setup procedure's content still needs a knowledge of AWS.
Self-learning can be beneficial, however, I found it really beneficial to share my expertise and common processes with my colleagues.

Most Important Features

Many on-premises server setups were successfully migrated to AWS.
They reacted strongly to the sensation of direction to travel to the cloud in the absence of equipment.
Cloud computing on an in-house system.

Return on Investment

There is no need to maintain infrastructural equipment.
There is no need to switch the electricity off or on in the case of a legitimate power outage.
The system frequently had issues when turned on, and labor frequently continued on all night, but by transferring to the cloud, that effort might be spared.
