Autoscaling is an important component of most cloud deployments these days. The core objective behind cloud computing is to allow users to only pay for the services they use. One way to achieve this is with elastic resources such as providing applications and infrastructure on demand. Autoscaling is part of this and here is an essential overview of the topic.
What is Autoscaling?
Autoscaling is a scaling method that gives users an automated approach to increase or decrease computing resources such as networking, storage, etc. according to traffic spikes other factors. In an infrastructure without autoscaling, resources are locked into configurations and are not flexible according to changing demands. Autoscaling allows cloud workloads and services to provide optimal performance under varying conditions. The technology is also vital in helping ensure service availability.
How Does It Work?
Autoscaling works in multiple ways depending on the type of resources and the platform used. But again, there are several common attributes across most autoscaling approaches enabling automatic scaling.
For resources such as compute, memory, and network, users define virtual instance types with specified capacities and predefined launch configurations or baseline deployment. With autoscaling technology-enabled, users define desired capacity constraints so that resources can be added as per fluctuations in traffic. However, the delivery of resources can also vary. In certain cases, the cloud service automatically provides more resource capacity whereas in others,. the set policies launch new resources adding to the total pool of virtual instances that the user deploys to meet demands.
Types and Benefits
There are three types of autoscaling. The first one is 'reactive' where resources scale up and down according to traffic and can be closely tied to real-time monitoring of the resources.
The second variety is called 'predictive' where tools such as machine learning and AI are used to determine traffic patterns and set scaling resources accordingly. The third type is called 'scheduled', where users can define resources according to predetermined time periods.
The major benefits of autoscaling cloud resources include:
- Improved performance
- Reduced costs
- Better fault tolerance
- Improved availability
