Amazon EC2 Auto Scaling

AWS EC2 Auto Scaling is well suited for you if you are using AWS EC2 instances for your deployment requirements and you want to build an auto-scaling solution. If you do not want to break down your deployment in between, you should set up the auto-scaling along with the load balancers.

EC2 Auto Scaling is a foundational component of high availability architectures in AWS. It allows one to dynamically scale in response to key metrics - such as CPU utilization on the web nodes - or schedule scaling based on anticipated events - such as a flash sale for an e-commerce site. By scaling horizontally, one saves money by not having to scale up to peak traffic. By maintaining manageable traffic loads on each of the nodes in the autoscaling group, one minimizes the incidence of nodes in the autoscaling group failing, which translates to higher availability of the application served by the instances. This is not to mention the possibility of hardware failure on the AWS side, a low likelihood but totally possible event. High availability is not purely a frontend or backend concern. Anything you can do with EC2s that benefits from high availability benefits from autoscaling.

If you need to establish a system right away, in the past it took weeks or months to request a quote from the vendor and receive the equipment. Now, with Amazon EC2 in less than tens of minutes or hours, you can create a test environment and test it without any inconvenience.

We were concerned about improving our billing by the method which helps us save charges for the resources. We were concerned to improve our billing by the method which helps us save charges for the resources that are not in use. Because it is a waste of resources as well as money so we use auto scaling which allows us not to sacrifice the performance by using fewer resources and saving bills

Amazon EC2's auto-scaling feature is straightforward to configure. It's also a reasonably simple process to follow. Scaling up or down has not been an issue. It is a perk of using AWS. Users should incorporate this feature into their work systems to get the most out of the cloud EC2 instance. Our apps and services won't have to guess resources. The tool does an excellent job of scaling up or down.

It is very useful option when we want to make our application or product more reliable and always try to maintain instance available. Some time feel delay in system after creating the instance other than that it has seamless experience

It is well suited for hosting files, websites, and applications on the internet rather than using multiple third parties.

Best suitable cases would be, the capacity the spin up and spin down the EC2 instances and the way it works with AWS resources is way to good. And the best part is the interconnection between these resources are totally taken care by AWS internally.

The place where AWS can improve is the timing it takes to spin up the instances in short span of time.

[Amazon EC2 Auto Scaling] is simple to set up and pretty self-explanatory. Never had issues around scaling up or down. [Now] we won't need to guess the capacity for our apps or services. The both scaling, up and down is simply perfect, you can actually stop checking every time for resources because this tool takes care of everything

When you have a simple auto scaling use case and it does not require complex rules.

I cannot think of any reason to NOT use EC2 auto-scaling except if you're just quickly testing something on a single instance and plan to terminate it after.

Its a beneficial feature provided by AWS. Users should make use of this feature in the work systems to have full benefit of the cloud EC2 instance.

It is great if you want something less sophisticated than Kubernetes. There is less complexity in scalling and there is freedom in configuring how you want to scale. Downside is that you can scale one particular micro service, maybe its not the best fit for a micro service based application.

Well suited when you really meet their requirement to handle increase/decrease resources based on demand. Without it, the process should be done manually and can be error-prone due to human intervention on repetitive tasks. Automation is the key word here. The problem would be the complexity or technicality it might add but with clear dev-ops team or documentation or a manual of how to use it might be fine.

Despite the problems with the lack of information (and help) on the new user interface, Amazon EC2 Auto Scaling is a terrific tool that show[s] us easily the power of "the cloud". Only a few years ago, increasing server capacity involved weeks or months of planning, and a hefty budget in some cases. Now, with the Auto Scaling capacity, you can increase and decrease capacity with a rule, and without a long commitment and investment on hardware.
