Blog > AWS Auto-Scaling and Benefits
For enterprises, a business organization has to spend a lot of money purchasing the infrastructure to set up some solution that requires a one-time cost. However, it is a burden for a business organization to procure server hardware software and then have a team of experts to manage all those infrastructures.
Every business needs a cost-efficient solution for their projects; AWS Auto-Scaling magically maintains the application performance based on the user requirements. At the lowest possible price, AWS, Auto-Scaling also manages the scalability with optimized cost.
AWS Cloud Scaling
Aws Auto-Scaling is a service that helps the user to monitor their applications and automatically adjusts the capacity to maintain steady, predictable performance at the lowest possible cost.
Benefits of Aws Auto-Scaling
Better Fault Tolerance: It gave better fault tolerance applications. Users can get the servers created and can have a blown copy of the servers. It also saves time and effort to deploy the applications again and again.
Better Cost Management: Aws Auto-Scaling provides better cost management because Aws’ scalability is automatically pre-scheduled on some threshold parameters.
Reliable Service: It is a reliable service, and whenever the scaling creates or initiate, users can get the notifications onto their mail IDs or their cell phones.
Scalability: Scalability is a core feature of Auto-Scaling; it can be scaled up or scaled down.
Flexibility: It has flexibility in terms of whenever users want to schedule this service, stop this service, or keep the size of the servers at a fixed number.
Availability: Auto Scaling service also provides better availability.
Snapshots Vs. AMI
Moreover, With Auto-Scaling, users can install multiple virtual machines in lesser time by using AWS Snapshots or AMI services.
| Snapshots | AMI |
| It is useful as a backup of a single EBS volume, just like a virtual hard drive attached to the EC2 instance. | AMI is useful as a backup of an EC2 instance. |
| The snapshots opt for this when the instance contains multiple static EBS volumes. | AMI allows users to replace a field EC2 instance. |
| Pay only for the storage of the modified data | Pay only for the storage that you use |
| It is a non-bootable image on EBS volume | It is a bootable image of the EC2 instance |
How Does Aws Auto-Scaling Work?
To further, the Aws Auto-Scaling, users have to configure a single unified scaling policy application resource. With that scaling policy, the user can explore the applications and select the service for scaling. Auto-scaling also provides two types of optimization: cost optimization and performance optimization to choose any optimization according to their needs. They can also keep track of scaling by monitoring or getting notifications.
Different Scaling Plans
- A scaling plan helps a user to configure a set of instructions for scaling based on software requirements.
- Scaling strategy guides the service of Aws Auto-Scaling on how to optimize resources in an application.
- With the scaling strategy, users can create their strategy based on the required metrics and thresholds.
Types of Scaling
Scaling consists of 2 types:
Dynamic Scaling: It guides the service of Aws Auto-Scaling on how to optimize resources. It is also helpful in optimizing resources for availability and price. With this scaling strategy, users can create their plans based on the required metrics and thresholds.
Predictive Scaling: Its objective is to predict future workload based on daily and weekly trends and regularly forecast future network traffic. It uses machine learning to analyze network traffic. This scaling is like how weather forecast work. Moreover, it also provides scheduled scaling actions to ensure that the resource capacity is available for application requirements.
